You are required to selectone word for each blank from a list of choices given in a word bankfollowing the passage. Read the passage through carefully before makingyour choices. Each choice in the bank is identified by a letter. Please markthe corresponding letter for each item on Answer Sheet 2 with a single linethrough the centre. You may not use any of the words in the bank more thanonce.When travelling overseas, do you buy water in plastic bottles or take your chances with tap water? Imagine you are wandering about on a Thai island or26 the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It's the safe thing to do, right? The bottle is 27_, and the label says "pure water. But maybe what’s inside is not so 28. Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29 microplastics?That’s the conclusion of a recently 30 study, which analysed 259 bottles from 11 brands sold in nine countries, 31 an average of 325 plastic particles per litre of water. These microplastics included a 32 commonly known as PET and widely used in the manufacture of clothing and food and 33 containers. The study was conducted at the State University of New York on behalf of Orb Media, a journalism organisation. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.Confronted with this 34 , several bottled- water manufacturers including Nestle and Coca Cola undertook their own studies using the same methodology. These studies showed that their water did contain microplastics,but far less than the Orb study suggested. Regardless, the World Health Organisation has launched a review into the 35 health risks of drinking water from plastic bottles.Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of theparagraphs. Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is markedwith a letter. Answer the questions by marking the corresponding letter onAnswer Sheet 2.The quiet heroism of mail deliveryA)On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colder than Antarctica (南极洲)，Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights were canceled.B)Even the United States Postal Service (USPS) suspended mail delivery.“Due to this arctic outbreak and concerns for the safety of USPS employees," USPS announced Wednesday morning, "the Postal Service is suspending delivery Jan. 30 in some 3-digit ZIP Code locations." Twelve regions were listed as unsafe on Wednesday; on Thursday, eight remained.C)As global surface temperatures increase, so does the likelihood of extreme weather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague Vann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck a community's infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal.D)Days after the deadly 2017 wildfires in Santa Rosa, California, a drone (无人机) caught footage (连续镜头) of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an effected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to Rae Ann Haight, the program manager for the national-preparedness office at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith,this was just another day on the job.“I followed my route like I normally do," Smith told a reporter.“As I came across a box that was up but with no house, I checked, and there was mail- outgoing mail- in it. And so we picked those up and carried on."E)USPS has sophisticated emergency plans for natural disasters. Across the country, 285 emergency-management teams are devoted to crisis control. These teams are trained annually using a framework known as the three Ps: people, property, product. After mail service stops due to weather, the agency's top priority is ensuring that employees are safe. Then it evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations. If the destruction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be protected from water damage.F)As soon as it's safe enough to be outside, couriers (邮递员) start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change- of-address forms with their new location. After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of locations across the country in the two weeks that USPS was unable to provide street delivery.G)Every day, USPS processes, on average, 493.4 million pieces of mail- -anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of ill are paid online, which means that just under half of payments still rely on delivery services to be completed.H)It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time.I)Mail companies are logistics(物流) companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the agency emphasized its massive infrastructure as a “unique federal asset” to be called upon ina disaster or terrorist attack. " I think we' re unique as a federal agency," USPS official Mike Swigart told me, “because we're in literally every community in this country... We're obligated to deliver to that point on a daily basis.”J)Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California. They also donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebuild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving,” he said.K) Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a normal life can be difficult, but some small routines -mail delivery being one of them may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “hat's the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies.38. Natural disasters can have a long: -lasting impact on community life.39. Mail delivery service is still responsible for the completion of almost half of payments.40. The sight of a mailman on the street is a reassuring sign of life becoming normal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up.42. Postal service in some regions in the U.S. was suspended due to extreme cold weather.43. Private postal companies also support disaster relief efforts by distributing urgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions.45. Postal services work hard to identify items that require priority treatment.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choicesmarked A), B), C) and D). You should decide on the best choice and markthe corresponding letter on Answer Sheet 2 with a single line through thecentre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge-Based Artificial Intelligence. This online course is a core requirement of Georgia Tech's online master's of science in computer science program. Professor Goel already had 8 teaching assistants, but that wasn't enough to deal with the overwhelming number of daily questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn't too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students' questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn't know she was a computer. The students, who were studying artificial intelligence, were interacting with virtual assistant and couldn't tellit apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all questions posed by students on the online forum. The name Jill Watson will, of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of artificial intelligence than, say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46. What do we learn about Knowledge Based Artificial Intelligence?A) It is a robot that can answer students’ questions.B)It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students' questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.49. How did the students feel about Jill Watson?A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill Watson?A) Launch different versions of her online.B) Feed her with new questions and answers.C) Assign her to ans wer more of students’ questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don’t hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional savvy may be more crucial.Crowd funding, raising money for a project through online appeals—has taken off in recent years for everything from making movies to producing water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goal, but others have fallen short of reaching even modest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich examined the content of the webpages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as and only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engagewith potential donors, since projects that answered questions from interested donors fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% receiving less than $ 1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably, the size of a scientist's personal and professional networks, and how much a researcher promotes a project on their own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers efforts to reach the public, and people give because they feel a connection to the person" who is doing the fundraising-not necessarily to the science.51. What do we learn about the scientists trying to raise money online for their projects?A) They did not raise much due to modest targets.B) They made use of mixed fund raising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schäfer's research of recent crowdfunding campaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projectsD) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations.B) Its interaction with prospective donors.C) Its originality in addressing financial issues.D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfunding projects?A) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C）The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre..Passage OneQuestions 46 to 50 are based on the following passage.The fifth largest city in the US passed a significant soda tax proposal that will levy (征税)1.5 cents per liquid ounce on distributors.Philadelphia's new measure was approved by a 13 to 4 city council vote. It sets a new bar for similar initiatives across the county. It is proof that taxes on sugary drinks can win substantial support outside super-liberal areas. Until now, the only city to successfully pass and implement a soda tax was Berkeley, Califomia, in 2014.The tax will apply to regular and diet sodas, as well as other drinks with added sugar, such as Gatorade and iced teas. It's expected to raise $410 million over the next five years, most of which will go toward funding a universal pre-kindergarten program for the city.While the city council vote was met with applause inside the council room, opponents to the measure, including soda lobbyists made sharp criticisms and a promise to challenge the tax in court.“The tax passed today unfairly singles out beverages-including low- and no-calorie choices”, said Lauren Kane, spokeswoman for the America n Beverage Association. “But most importantly, it is against the law. So we will side with the majority of the people of Philadelphia who oppose this tax and take legal action to stop it. “An industry backed anti- tax campaign has spent at least S4 million on advertisements. The ads criticized the measure. characterizing it as a “grocery tax.”Public health groups applauded the approved tax as a step toward fixing certain lasting health issues that plague Americans. “The move to recapture a small part of t he profits from an industry that pushes a product that contributes to diabetes, obesity and heart disease in poorer communities in order to reinvest in those communities will sure be inspirational to many other places”, said Jim Krieger, executive director of Healthy Food America. Indeed, we are already hearing from some of them. “It's not just Berkeley anymore.”Similar measures in California's Albany, Oakland, San Francisco and Colorado's boulder are becoming hot-button issues Health advocacy groups have hinted that even more might be coming46. What does the passage say about the newly-approved soda tax in Philadelphia?A) It will change the lifestyle of many consumersB) It may encourage other US cities to follow suit.C) It will cut soda consumption among low-income communitiesD) It may influence the marketing strategies of the soda business47. What will the opponents probably do to respond to the soda tax proposal?A) Bargain with the city council.B) Refuse to pay additional tax.C) Take legal action against itD) Try to win public support.48. What did the industry-backed anti-tax campaign do about the soda tax proposalA) It tried to arouse hostile feelings among consumersB) It tried to win grocers support against the measureC) It kept sending letters of protest to the mediaD) It criticized the measure through advertising49. What did public health groups think the soda tax would do?A) Alert people to the risk of sugar-induced diseases.B) Help people to fix certain long-time health issues.C) Add to the fund for their research on diseases.D) Benefit low-income people across the country50.What do we learn about similar measures concerning the soda tax in some other cities?A)They are becoming rather sensitive issues.B) They are spreading panic in the soda industry.C)They are reducing the incidence of sugar-induced diseases.D)They are taking away lot of profit from the soda industryPassage TwoPopping food into the microwave for a couple of minutes may seem utterly harmless, but Europe’s stock of these quick-cooking ovens emit as much carbon as nearly 7 million cars, a new study has found. And the problem is growing. With costs falling and kitchen appliances becoming “status" items, owners are throwing away microwaves after an average of eight years. This is pushing sales of new microwaves which are expected to reach 135 million annually in the EU by the end of the decadeA study by the University of Manchester calculated the emissions of co2-the main greenhouse gas responsible for climate change-at every stage of microwaves, from manufacture to waste disposal. “It is electricity consumption by microwaves that has the biggest impact on th e environment," say the authors. The authors also calculate that the emissions from using 19 microwaves over a year are the same as those from using a car. According to the same study, efforts to reduce consumption should focus on improving consumer awareness and behaviour . For example, consumers could use appliances in a more efficient way by adjusting the time of cooking to the type of food.However, David Reay, professor of carbon management, argues that, although microwaves use a great deal of energy, their emissions are minor compared to those from cars. In the UK alone, there are around 30 million cars These cars emit more than all the microwaves in the EU. Backing this up, recent data show that passenger cars in the UK emitted 69 million tons of CO2 in 2015. This is 10 times the amount this new microwave oven study estimates for annual emissions for all the microwave ovens in the EU. Further, the energy used by microwaves is lower than any other form of cooking. Among common kitchen appliances used for cooking,microwaves are the most energy efficient, followed by a stove and finally a standard oven. Thus, rising microwave sales could be seen as a positive thing.51.What is the finding of the new study?A)Quick-cooking microwave ovens have become more popular.B) The frequent use of microwaves may do harm to our health.C) CO2 emissions constitute a major threat to the environmentD）The use of microwaves emits more CO than people think .52.Why are the sales of microwaves expected to rise？A)They are becoming more affordable.B)They have a shorter life cycle than other appliances .C) They are getting much easier to operate.D) They take less time to cook than other appliances.53. What recommendation does the study by the University of Manchester make?A) Cooking food of different varieties.B) Improving microwave user’s habits.C) Eating less to cut energy consumption.D) Using microwave ovens less frequently.54. What does Professor David Reay try to argue?A) There are far more emissions from cars than from microwaves.B) People should be persuaded into using passenger cars less oftenC) The UK produces less CO than many other countries in the EUD) More data are needed to show whether microwaves are harmful.55. What does Professor David Reay think of the use of microwaves?A) It will become less popular in the coming decades.B) It makes everyday cooking much more convenient.C) It plays a positive role in environmental protection.D) It consumes more power than conventional cooking【参考答案】46-50 D C A D C51-55 C B B A DPart Ⅳ Translation( 30 minutes) Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Each paragraph is markedwith a letter: Answer the questions by marking the corresponding letteron Answer Sheet 2.The Quiet Heroism of Mail Delivery'·[A] On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight,Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colderthan Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zeroin Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota,according to the National Weather Service. Schools, restaurants, and businessesclosed, and more than l ,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail deliverytemporarily. "Due to this arctic outbreak and concerns for the safety of USPSemployees," USPS announced Wednesday morning, the Postal Service is suspendingdelivery Jan. 30 in the following 3-digit ZIP Code locations." Twelve regions werelisted as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extremeweather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and othernatural disasters cost at least $49 billion in the United States. As my colleague VannNewkirk reported, Puerto Rico is still confronting economic and structural destructionand resource scarcity from 2017's Hurricane Maria. Natural disasters can wreck acommunity's infrastructure, disrupting systems for months or years. Some services,however, remind us that life will eventually return, in some form, to normal,[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a dronecaught footage of a USPS worker, Trevor Smith, driving through burned homes in thatfamiliar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to RaeAnn Haight, the program manager for the national-preparedness office at USPS,Smith was fulfilling a request made by some of the home owners to pick up any mailthat was left untouched. For Smith, this was just another day on the job. I followedmy route like I normally do," Smith told a reporter. As I'd come across a box thatwas up but with no house, I checked, and there was mail--outgoing mail--in it. Andso we picked those up and carried on.'[E] USPS has sophisticated emergency plans for natural disasters. Across thcountry, 285 emergency-management teams are devoted to crisis control. These teamsare trained annually using a framework known as the three Ps: people, property,product. After mail service stops due to weather, the agency 's top priority is ensuringthat employees are safe. Then it evaluates the health of infrastructure, such as theroads that mail carriers drive on. Finally, it decides when and how tore-openoperations. If the destruction is extreme, mail addressed to the area will get sentelsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming NewOrleans mail to existing mail facilities in Houston. Mail that was already processed inNew Orleans facilities was moved to an upper floor so it would be protected fromwater damage.[F] As soon as it's safe enough to be outside,' couriers start distributingaccumulated mail on the still-accessible routes. USPS urges those without standingaddresses to file change-of- address forms with their new location. After HurricaneKatrina hit in 2005, mail facilities were set up in dozens of other locations across thecountry in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces ofmail -anything from postcards to Social Security checks to medicine. Spokespeoplefrom both USPS and UPS told me all mail is important. But some mail can beextremely sensitive and timely. According to data released in January 2017, 56percent of bills are paid online, which means that just under half of payments still relyon delivery services to be completed.[H] It can be hard to identify which parcels are carrying crucial items such asSocial Security checks, but USPS and UPS try their best to prioritize sensitivematerial. They will coordinate with the Social Security Administration to make surethat Social Security checks reach the right people in a timely fashion. After HurricaneFlorence and Hurricane Michael last fall, USPS worked with state and local electionboards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special positionto help when disaster strikes. In a 2011 USPS case study, the agency emphasized itsmassive infrastructure as a unique federal asset" to be called upon in a disaster orterrorist attack. I think we're unique as a federal agency," USPS official MikeSwigart told me, because we're in literally every community in this countryWe' re obligated to deliver to that point on a daily basis.'[J] Private courier companies, which have more dollars to spend, use theirexpertise in logistics to help revitalize damaged areas after a disaster. For more than adecade, FedEx has supported the American Red Cross in its effort to get emergencysupplies to areas affected by disasters, both domestically and internationally. In 2012,the company distributed more than 1,200 MedPacks to Medical Reserve Corps groupsin California, and donated space for 3.1 million pounds of charitable shipping st October, the company pledged $1 million in cash and transportation support forHurricanes Florence and Michael. UPS's charitable arm, the UPS Foundation, usesthe company 's logistics to help disaster-struck areas rebuild. We realize that as acompany with people, trucks, warehouses, we needed to play a larger role," saidEduardo Martinez, the president of the UPS Foundation. The company employs it:trucks and planes to deliver food, medicine, and water. The day before I spoke toMartinez in November, he had been touring the damage fromHurricane Michael inFlorida with the American Red Cross. We have an obligation to make sure ourcommunities are thriving, prosperous," he said.[K] Rebuilding can take a long time, and even then, impressions of the disastermay still remain. Returning to a sense of normalcy can be difficult, but some smallroutines--mail delivery being one of them--may help residents remember that theircommunities are still their communities. When they see that carrier back out on thestreet," Swigart said, that's the first sign to them that life is starting to return tonormal."36. The United States Postal Service has a system to ensure its employees' safety.37. One official says USPS is unique in that it has more direct reach tccommunities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half ofpayments.40. The sight of a mailman on the street is a reassuring sign of life becomingnormal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail servicepoints were set up.42. Postal service in some regions in the U.S. was suspended due to extreme coldweather.43. Private postal companies also support disaster relief efforts by distributingurgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite ofextreme conditions.45. Postal services work hard to identify items that require priority treatment. Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single line 'through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligentteaching assistant to help handle the enormous number of student questions in theonline class, Knowledge Based Artificial Intelligence. This online course is a corerequirement of Georgia Tech's online Master of Science in Computer Scienceprogram. Professor Goel already had 8 teaching assistants, but that wasn t enough todeal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support.When students feel isolated or confused and reach out with questions that gounanswered, their motivation to continue begins to fade. Professor Goel decided to dosomething to remedy this situation and his solution was to create a virtual assistantnamed Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill W atson before releasing herto the online forums. At first, the virtual assistant wasnt too great. But Goel and histeam sourced the online discussion forum to find all 40,000 questions that had everbeen asked since the class was launched. Then they began to feed Jill the questionsand answers. After some adjustment and sufficient time, Jill was able to answer thestudents questions correctly 97% of the time. The L virtual assistant became soadvanced and realistic that the students didn t know she was a computer. The students,who were studying artificial intelligence, were interacting with artificial intelligenceand couldn't tell it apart from a real human being. Goel didn 't inform them about Jill'strue identity until April 26. The students were actually very positive about theexperience.The goal of Professor Goel's virtual assistant next year is to take over answering40% of all questions posed by students on the online forum. The name, Jill Watson,will of course, change to something else next semester. Professor Goel has a muchrosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gatesor Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students' questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.10/23149. How did the students feel about Jill W atson?A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill W atson?A) Launch different versions of her online.B) Feed her with new questions and answers.c) Assign her to answer more of students questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don' t hurt. Thoseare a few of the traits of successful science crowdfunding efforts that emerge from arecent study that examined nearly 400 campaigns. But having a large network andsome promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken offin recent years for everything from making movies to building water-saving gadgets.Scientists have tried to tap Internet donors, too, with mixed success. Some raisedmore than twice their goal, but others have fallen short of reaching more modesttargets.To determine what separates science crowdfunding triumphs from failures, ateam led by science communications scholar Mike Schäfer of the University of Zurichin Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report inPublic Understanding of Science. For one, they use a crowdfunding platform thatspecializes in raising money for science, and not just any kind of project. Althoughsites like Kickstarter take all comers, platforms such as Experiment.com,, and Petridish. org only present scientific projects. For another, theypresent the project with a funny video because good visuals and a sense of humorimproved success. Most of them engage with potential donors since projects thatanswered questions from interested donors and posted lab notes fared better. And theytarget a small amount of money. The projects included in the study raised $4000 onaverage, with 30% of projects receiving less than $ 1000. The more money a projectsought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project's success, most notably,the size of a scientist's personal and professional networks, and how muchresearcher promotes a project on his or her own. Those two factors are by far morecritical than the content on the page. Crowdfunding can be part of researchers effortsto reach the public, and people give because they feel a connection to the person"who is doing the fundraising--not necessarily to the science.11/3151. What do we learn about the scientists trying to raise money online for theirprojects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schafer's research of recent crowdfundingcampaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations.为B) Its interaction with prospective donors.C) Its originality in addressing financial issues.D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfundingprojects?A) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care.D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part IV Translation (30 minutes) Directions: For this part, you cre allowed 30 minutes to translate a passage from ( 'hinese into English.

After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of other locations across the country in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces of mail—anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed. [H] It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the agency emphasized its massive infrastructure as a “unique federal asset” to be called upon in a disaster or terrorist attack. “I think we’re unique as a federal agency,” USPS official Mike Swigart told me, “because we’re in literally every community in this country … We’re obligated to deliver to that point on a daily basis.”[J] Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California, and donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebuild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving, prosperous,” he said.[K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half of payments.40. The sight of a mailman on the street is a reassuring sign of life becoming normal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up.42. Postal service in some regions in the U.S. was suspended due to extreme cold weather.43. Private postal companies also support disaster relief efforts by distributing urgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions.45. Postal services work hard to identify items that require priority treatment.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor Goel already had 8 teaching assistants, but that wasn’t enough to deal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with artificial intelligence and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all questions posed by students on the online forum. The name, Jill Watson, will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students’ questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students’ questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success.B) She got along pretty well with students.C) She was unwelcome to students at first.D) She was released online as an experiment.49. How did the students feel about Jill Watson?A) They thought she was a bit too artificial.B) They found her not as capable as expected.C) They could not but admire her knowledge.D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill Watson?A) Launch different versions of her online.B) Feed her with new questions and answers.C) Assign her to answer more of students’ questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don’t hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to building water-saving gadgets. Scientists have tried to tap Internet donors,too, with mixed success. Some raised more than twice their goal, but others have fallen short of reaching more modest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich in Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as , , and only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors since projects that answered questions from interested donors and posted lab notes fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% of projects receiving less than $1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project’s success, most notably, the size of a scientist’s personal and professional networks, and how much a researcher promotes a project on his or her own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers’ efforts to reach the public, and people give because “they feel a connection to the person” who is doing the fundraising—not necessarily to the science.51. What do we learn about the scientists trying to raise money online for their projects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schäfer’s research of recent crowdfunding campaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations. B) Its interaction with prospective donors.C) Its originality in addressing financial issues.D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfunding projects?A) They should be small to be successful.B) They should be based on actual needs.C) They should be assessed with great care. D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part Ⅱ Translation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Finally, when thepassage is read for the third time, you should check what you havewritten.“Don’t take many English courses; they won’t help you get a decent job.”“Sign up for management classes, so you’ll be ready to join the family business when you graduate.”Sound 26 ? Many of us have heard suggestions like these 27 by parents or others close to us. Such comments often seem quite reasonable.Why, then, should suggestions like these be taken with 28 ? The reason is they relate to decisions you should make. You are the one who must 29 their consequences.One of the worst reasons to follow a particular path in life is that other people want you to. Decisions that affect your life should be your decisions—decisions you make after you’ve considered various 30 and chosen the path that suits you best.Making your own decisions does not mean that you should 31 the suggestions of others. For instance, your parents do have their own unique experiences that may make their advice helpful, and having 32 in a great deal of your personal history, they may have a clear view of your strengths and weaknesses. Still, their views are not necessarily accurate. They may still see you as a child, 33 care and protection. Or they may see only your strengths.

Ultimately, though, you have to make your own 35 .Part III Reading Comprehension (40 minutes) Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a wordbank following the passage: Read the passage through carefully beforemaking your choices. Each choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet 2with a single line through the centre. You may not use any of the words inthe bank more than once.Questions 36 to 45 are based on the following passage.One principle of taxation, called the benefits principle, states that people should pay taxes based on the benefits they receive from government services. This principle tries to make public goods similar to 36 goods. It seems reasonable that a person who often goes to the movies pays more in 37 for movie tickets than a person who rarely goes. And 38 , a person who gets great benefit from a public good should pay more for it than a person who gets little benefit.The gasoline tax, for instance, is sometimes 39 using the benefits principle. In some states, 40 from the gasoline tax are used to build and maintain roads. Because those who buy gasoline are the same people who use the roads, the gasoline tax might be viewed as a 41 way to pay for this government service.The benefits principle can also be used to argue that wealthy citizens should pay higher taxes than poorer ones, 42 because the wealthy benefit more from public services. Consider, for example, the benefits of police protection from 43 . Citizens with much to protect get greater benefit from police than those with less to protect. Therefore, according to the benefits principle, the wealthy should 44 more than the poor to the cost of 45 the police force. The same argument can be used for many other public services, such as fire protection, national defense, and the court system.Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of theparagraphs. Identify the paragraph from which the information is derived.You may choose a paragraph more than once. Each paragraph is markedwith a letter. Answer the questions by marking the corresponding letteron Answer Sheet 2.Grow up Colored[A] You wouldn’t know Piedmont anymore—my Piedmont, I mean—the town inWest Virginia where I learned to be a colored boy.[B] The 1950s in Piedmont was a time to remember, or at least to me. People werealways proud to be from Piedmont—lying at the foot of a mountain, on the banks of the mighty Potomac. We knew God gave America no more beautiful location.I never knew colored people anywhere who were crazier about mountains andwater, flowers and trees, fishing and hunting. For as long as anyone could remember, we could outhunt, outshoot, and outswim the white boys in the valley.[C] The social structure of Piedmont was something we knew like the back of ourhands. It was an immigrant town; white Piedmont was Italian and Irish, with a handful of wealthy WASPs (盎格鲁撒克逊裔的白人新教徒) on East Hampshire Street, and "ethnic" neighborhoods of working-class people everywhere else, colored and white.[D] For as long as anyone can remember, Piedmont’s character has been completelybound up with the Westvaco paper mill: its prosperous past and doubtful future.At first glance, the town is a typical dying mill center. Many once beautiful buildings stand empty, evidencing a bygone time of spirit and pride. The big houses on East Hampshire Street are no longer proud, as they were when I was a kid.[E] Like the Italians and the Irish, most of the colored people migrated to Piedmont atthe turn of the 20th century to work at the paper mill, which opened in 1888. All the colored men at the paper mill worked on “the platform”—loading paper into trucks until the craft unions were finally integrated in 1968. Loading is what Daddy did every working day of his life. That’s what almost every colored grown-up I knew did.[F] Colored people lived in three neighborhoods that were clearly separated. Welcometo the Colored Zone, a large stretched banner could have said. And it felt good in there, like walking around your house in bare feet and underwear, or snoring (打鼾) right out loud on the couch in front of the TV—enveloped by the comforts of home, the warmth of those you love.[G] Of course, the colored world was not so much a neighborhood as a condition ofexistence. And though our own world was seemingly self-contained, it impacted on the white world of Piedmont in almost every direction. Certainly, the borders of our world seemed to be impacted on when some white man or woman showed up where he or she did not belong, such as at the black Legion Hail. Our space was violated when one of them showed up at a dance or a party. The rhythms would be off. The music would sound not quite right. Everybody would leave early.[H] I Before 1955, most white people were just shadowy presences in our world,vague figures of power like remote bosses at the mill or clerks at the bank. There were exceptions, of course, the white people who would come into our world in routine, everyday ways we all understood. Mr. Mail Man, Mr. Insurance Man, Mr.White-and-Chocolate Milk Man, Mr. Landlord Man, Mr. Police Man: we called white people by their trade, like characters in a mystery play. Mr. Insurance Man would come by every other week to collect payments on college or death policies, sometimes 50 cents or less.[I] “It’s no disgrace to be colored,”the black entertainer Bert Williams famouslyobserved early in the century, “but it is awfully inconvenient.”For most of my childhood, we couldn’t eat in restaurants or sleep in hotels, we couldn’t use certain bathrooms or try on clothes in stores. Mama insisted that we dress up when we went to shop. She was carefully dressed when she went to clothing stores, and wore white pads called shields under her arms so her dress or blouse would show no sweat. “We’d like to try this on,” she’d say carefully, uttering her words precisely and properly. “We don’t buy clothes we can’t try on,” she’d say when they declined, and we’d walk out in Mama’s dignified (有尊严的) manner.She preferred to shop where we had an account and where everyone knew who she was.[J] At the Cut-Rate Drug Store, no one colored was allowed to sit down at the counter or tables, with one exception: my father. I don’t know for certain why Carl Dadisman, the owner, wouldn’t stop Daddy from sitting down. But I believe it was in part because Daddy was so light-colored, and in part because, during his shift at the phone company, he picked up orders for food and coffee for the operators. Colored people were supposed to stand at the counter, get their food to go, and leave. Even when Young Doc Bess would set up the basketball team with free Cokes after one of many victories, the colored players had to stand around and drink out of paper cups while the white players and cheerleaders sat down in comfortable chairs and drank out of glasses.[K] I couldn’t have been much older than five or six as I sat with my father at the Cut-Rate one afternoon, enjoying ice cream. Mr. Wilson, a stony-faced Irishman, walked by. “Hello, Mr. Wilson,” my father said.“Hello, George.”[L] I was genuinely puzzled. Mr. Wilson must have confused my father with somebody else, but who? There weren’t any Georges among the colored people in Piedmont. “Why don’t you tell him your name, Daddy?” I asked loudly. “Your name isn’t George.”“He knows my name, boy,”my father said after a long pause. “He calls all colored people George.”[M] I knew we wouldn’t talk about it again; even at that age, I was given to understand that there were some subjects it didn’t do to worry to death about.Now that I have children, I realize that what distressed my father wasn’t so much the Mr. Wilsons of the world as the painful obligation to explain the racial facts of life to someone who hadn’t quite learned them yet. Maybe Mr. Wilson couldn’t hurt my father by calling him George; but I hurt him by asking to know why.46.The author felt as a boy that his life in a separated neighborhood was casual andcozy.47.There is every sign of decline at the paper mill now.48.One reason the author’s father could sit and eat at the drug store was that he didn’tlook that dark.49.Piedmont was a town of immigrants from different parts of the world.50.In spite of the awful inconveniences caused by racial prejudice, the author’sfamily managed to live a life of dignity.51.The author later realized he had caused great distress to his father by asking whyhe was wrongly addressed.52.The author took pride in being from Piedmont because of its natural beauty.53.Colored people called white people by the business they did.54.Colored people who lived in Piedmont did heavy manual jobs at the paper mill.55.The colored people felt uneasy at the presence of the whites in theirneighborhoods.Section CDirections:There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are fourchoices marked A), B), C) and D). You should decide on the best choiceand mark the corresponding letter on Answer Sheet 2 with a single linethrough the centre.Passage OneQuestions 56 to 60 are based on following passage.Children are a delight. They are our future. But sadly, hiring someone to take care of them while you go to work is getting more expensive by the year.Earlier this month, it was reported that the cost of enrolling an infant or small kid at a childcare center rose 3% in 2012, faster than the overall cost of living. There are now large strips of the country where daycare for an infant costs more than a tenth of the average married couple’s income.This is not necessarily a new trend, but it is a somewhat puzzling one. The price of professional childcare has been rising since the 1980s. Yet during that time, pay for professional childcare workers has stood still. Actually caregivers make less today, in real terms, than they did in 1990. Considering that labor costs are responsible for up to 80% of a daycare center’s expenses, one would expect flat wages to have meant flat prices.So who’s to blame for higher childcare costs?Childcare is a carefully regulated industry. States lay down rules about how many children each employee is allowed to watch over, the space care centers need per child, and other minute details. And the stricter the regulations, the higher the costs. If it has to hire a caregiver for every two children, it can’t really achieve any economies of scale on labor to save money when other expenses go up. In Massachusetts, where childcare centers must hire one teacher for every three infants, the price of care averaged more than $16,000 per year. In Mississippi, where centers must hire one teacher for every five infants, the price of care averaged less than $5,000.Unfortunately, I don’t have all the daycare-center regulations handy. But I wouldn’t be surprised if as the rules have become more elaborate, prices have risen. The tradeoff (交换) might be worth it in some cases; after all, the health and safety of children should probably come before cheap service. But certainly, it doesn’t seem to be an accident that some of the cheapest daycare available is in the least regulated South.56. What problem do parents of small kids have to face?A) The ever-rising childcare prices.B) The budgeting of family expenses.C) The balance between work and family.D) The selection of a good daycare center.57. What does the author feel puzzled about?A) Why the prices of childcare vary greatly from state to state.B) Why increased childcare prices have not led to better service.C) Why childcare workers’ pay has not increased with the rising childcare costs.D) Why there is a severe shortage of childcare professionals in a number ofstates.58. What prevents childcare centers from saving money?A) Steady increase in labor costs.B) Strict government regulations.C) Lack of support from the state.D) High administrative expenses.59. Why is the average cost of childcare in Mississippi much lower than inMassachusetts?A) The overall quality of service is not as good.B) Payments for caregivers there are not as high.C) Living expenses there are comparatively low.D. Each teacher is allowed to care for more kids.60. What is the author’s view on daycare service?A) Caregivers should receive regular professional training.B) Less elaborate rules about childcare might lower costs.C) It is crucial to strike a balance between quality and costs.D) It is better for different states to learn from each other.Passage TwoQuestions 61 to 65 are based on the following passage.Alex Pang’s amusing new book The Distraction Addiction addresses those of us who feel panic without a cellphone or computer. And that, he claims, is pretty much all of us. When we’re not online, where we spend four months annually, we’re engaged in the stressful work of trying to get online.The Distraction Addiction is not framed as a self-help book. It’s a thoughtful examination of the dangers of our computing overdose and a historical overview of how technological advances change consciousness. A “professional futurist”, Pang urges an approach which he calls “contemplative (沉思的) computing.” He asks that you pay full attention to “how your mind and body interact with computers and how your attention and creativity are influenced by technology.”Pang’s first job is to free you from the common misconception that doing two things at once allows you to get more done. What is commonly called multitasking is,in fact, switch-tasking, and its harmful effects on productivity are well documented. Pang doesn’t advocate returning to a pre-Internet world. Instead, he asks you to “take a more ecological (生态的) view of your relationships with technologies and look for ways devices or media may be making specific tasks easier or faster but at the same time making your work and life harder.”The Distraction Addiction is particularly fascinating on how technologies have changed certain fields of labor-often for the worse. For architects, computer-aided design has become essential but in some ways has cheapened the design process. As one architect puts it, “Architecture is first and foremost about thinking.., and drawing is a more productive way of thinking” than computer-aided design.Somewhat less amusing are Pang’s solutions for kicking the Internet habit. He recommends the usual behavior-modification approaches, familiar to anyone who has completed a not smoking program. Keep logs to study your online profile and decide what you can knock out, download a program like Freedom that locks you out of your browser, or take a “digital Sabbath (安息日)”: “Unless you’re a reporter or emergency-department doctor, you’ll discover that your world doesn’t fall apart when you go offline.”61. Alex Pang’s new book is aimed for readers who ______.A) find their work online too stressfulB) go online mainly for entertainmentC) are fearful about using the cellphone or computerD) can hardly tear themselves away from the Internet62. What does Alex Pang try to do in his new book?A) Offer advice on how to use the Internet effectively.B) Warn people of the possible dangers of Internet use.C) Predict the trend of future technological development.D) Examine the influence of technology on the human mind.63.

You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.When travelling overseas, do you buy water in plastic bottles or take your chances with tap water? Imagine you are wandering about on a Thai island or 26 the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It’s the safe, sane thing to do, right? The bottle is 27 , and the label says “pure water”, but maybe what’s inside is not so 28 . Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29 microplastics?That’s the conclusion of a recently 30 study, which analyzed 259 bottles from 11 brands sold in nine countries, 31 an average of 325 plastic particles per liter of water. These microplastics included a 32 commonly known as PET and are widely used in the manufacture of clothing and food and 33 containers. The study was conducted at the State University of New York on behalf of Orb Media, a journalism organization. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.Confronted with this 34 , several bottled-water manufacturers including Nestle and Coco-Cola undertook their own studies using the same methodology. These studies showed that their water did contain microplastics, but far less than the Orb study suggested. Regardless, the World Health Organization has now launched a review into the 35 health risks of drinking water from plastic bottles.Section BDirections: In this section, you are going to read a passage with ten statements attached to each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Quiet Heroism of Mail Delivery[A] On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21degrees Fahrenheit below zero, making it slightly colder than Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail delivery temporarily. “Due to this arctic outbreak and concerns for the safety of USPS employees,” USPS announced Wednesday morning, “the Postal Service is suspending delivery Jan. 30 in the following 3-digit ZIP Code locations.” Twelve regions were listed as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extreme weather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague V ann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017’s Hurricane Maria. Natural disasters can wreck a community’s infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal.[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a drone caught footage of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. The video is striking: The operation is familiar, but the scene looks like the end of the world. According to Rae Ann Haight, the program manager for the national-preparedness office at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith, this was just another day on the job. “I followed my route like I normally do,” Smith told a reporter. “As I’d come across a box that was up but with no house, I checked, and there was mail—outgoing mail—in it. And so we picked those up and carried on.”[E] USPS has sophisticated emergency plans for natural disasters. Across the country, 285 emergency-management teams are devoted to crisis control. These teams are trained annually using a framework known as the three Ps: people, property, product. After mail service stops due to weather, the agency’s top priority is ensuring that employees are safe. Then it evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations. If the destruction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be protected from water damage.[F] As soon as it’s safe enough to be outside, couriers start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change-of-address forms with their new location. After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of other locations across the country in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces of mail—anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed. [H] It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special position to help when disaster strikes.In a 2011 USPS case study, the agency emphasized its massive infrastructure as a “unique federal asset” to be called upon in a disaster or terrorist attack. “I think we’re unique as a federal agency,” USPS official Mike Swigart told me, “because we’re in literally every community in this country … We’re obligated to deliver to that point on a daily basis.”[J] Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California, and donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebuild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,”said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving, prosperous,” he said.[K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half of payments.40. The sight of a mailman on the street is a reassuring sign of life becoming normal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up.42. Postal service in some regions in the U.S. was suspended due to extreme cold weather.43. Private postal companies also support disaster relief efforts by distributing urgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions.45. Postal services work hard to identify items that require priority treatment.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor Goel already had 8 teaching assistants, but that wasn’t enough to deal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support. When students feelisolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students’questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with artificial intelligence and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all questions posed by students on the online forum. The name, Jill Watson, will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students’ questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students’ questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success. B) She got along pretty well with students.C) She was unwelcome to students at first. D) She was released online as an experiment.49. How did the students feel about Jill Watson?A) They thought she was a bit too artificial. B) They found her not as capable as expected.C) They could not but admire her knowledge. D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill Watson?A) Launch different versions of her online.B) Feed her with new questions and answers.C) Assign her to answer more of students’ questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being engaging, and having a sense of humor don’t hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to building water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goal, but others have fallen short of reaching moremodest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich in Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as , , and only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors since projects that answered questions from interested donors and posted lab notes fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% of projects receiving less than $1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project’s success, most notably, the size of a scientist’s personal and professional networks, and how much a researcher promotes a project on his or her own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researchers’efforts to reach the public, and people give because “they feel a connection to the person” who is doing the fundraising—not necessarily to the science.51. What do we learn about the scientists trying to raise money online for their projects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schäfer’s research of recent crowdfunding campaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations. B) Its interaction with prospective donors.C) Its originality in addressing financial issues. D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfunding projects?A) They should be small to be successful. B) They should be based on actual needs.C) They should be assessed with great care. D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part ⅣTranslation (30 minutes)Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

on Answer Sheet2.Is Breakfast Really the Most Important Meal of the Day?[A]Along with old classics like“carrots give you night vision”and“Santa doesn’t bring toys to misbehaving children”,one of the most well-worn phrases of tired parents everywhere is that breakfast is the most important meal of the day.Many of us grow up believing that skipping breakfast is a serious mistake,even if only two thirds of adultsin the UK eat breakfast regularly,according to the British Dietetic Association,and around three-quarters of Americans.[B]“The body uses a lot of energy stores for growth and repair through the night,”explains diet specialist Sarah Elder.“Eating a balanced breakfast helps to up our energy, as well as make up for protein and calcium used throughout the night.”But there’s widespread disagreement over whether breakfast should keep its top spot in the hierarchy(等级)of meals.There have been concerns around the sugar content of cereal and the food industry’s involvement in pro-breakfast research—and even one claim from an academic that breakfast is“dangerous”.[C]What’s the reality?Is breakfast a necessary start to the day or a marketing tactic by cereal companies?The most researched aspect of breakfast(and breakfast-skipping) has been its links to obesity.Scientists have different theories as to why there’s a relationship between the two.In one US study that analysed the health data of50,000 people over seven years,researchers found that those who made breakfast the largest meal of the day were more likely to have a lower body mass index(BMI)than those who ate a large lunch or dinner.The researchers argued that breakfast helps reduce daily calorie intake and improve the quality of our diet—since breakfast foods are often higher in fibre and nutrients.[D]But as with any study of this kind,it was unclear if that was the cause—or if breakfast-skippers were just more likely to be overweight to begin with.To find out, researchers designed a study in which52obese women took part in a12-week weightloss programme.All had the same number of calories over the day,but half had breakfast,while the other half did not.What they found was that it wasn’t breakfast itself that caused the participants to lose weight:it was changing their normal routine.[E]If breakfast alone isn’t a guarantee of weight loss,why is there a link between obesity and breakfast-skipping?Alexandra Johnstone,professor of appetite research at the University of Aberdeen,argues that it may simply be because breakfast-skippers have been found to be less knowledgeable about nutrition and health.“There are a lot of studies on the relationship between breakfast eating and possible health outcomes, but this may be because those who eat breakfast choose to habitually have health-enhancing behaviours such as regular exercise and not smoking,”she says.[F]A2016review of10studies looking into the relationship between breakfast and weight management concluded there is“limited evidence”supporting or refuting(反驳) the argument that breakfast influences weight or food intake,and more evidence is required before breakfast recommendations can be used to help prevent obesity.[G]Researchers from the University of Surrey and University of Aberdeen are halfway through research looking into the mechanisms behind how the time we eat influences body weight.Early findings suggest that a bigger breakfast is beneficial to weight control.Breakfast has been found to affect more than just weight.Skipping breakfast has been associated with a27%increased risk of heart disease,a21%higher risk of type2diabetes in men,and a20%higher risk of type2diabetes in women.One reason may be breakfast’s nutritional value—partly because cereal is fortified(增加营养价值)with vitamins.In one study on the breakfast habits of1,600young people in the UK,researchers found that the fibre and micronutrient intake was better in those who had breakfast regularly.There have been similar findings in Australia,Brazil,Canada and the US.[H]Breakfast is also associated with improved brain function,including concentration and language use.A review of54studies found that eating breakfast can improve memory,though the effects on other brain functions were inconclusive.However,one of the review’s researchers,Mary Beth Spitznagel,says there is“reasonable”evidence breakfast does improve concentration—there just needs to be more research.“Looking at studies that tested concentration,the number of studies showing a benefit was exactly the same as the number that found no benefit,”she says.“And no studies found that eating breakfast was bad for concentration.”[I]What’s most important,some argue,is what we eat for breakfast.High-protein breakfasts have been found particularly effective in reducing the longing for food and consumption later in the day,according to research by the Australian Commonwealth Scientific and Industrial Research Organisation.While cereal remains a firm favourite among breakfast consumers in the UK and US,a recent investigation into the sugar content of“adult”breakfast cereals found that some cereals contain more than three-quarters of the recommended daily amount of free sugars in each portion,and sugar was the second or third highest ingredient in cereals.[J]But some research suggests if we’re going to eat sugary foods,it’s best to do it early.One study recruited200obese adults to take part in a16-week-long diet,where half added dessert to their breakfast,and half didn’t.Those who added dessert lost an average of40pounds more—however,the study was unable to show the long-term effects.A review of54studies found that there is no consensus yet on what type of breakfast is healthier,and concluded that the type of breakfast doesn’t matter as much as simply eating something.[K]While there’s no conclusive evidence on exactly what we should be eating and when,the consensus is that we should listen to our own bodies and eat when we’re hungry.“Breakfast is most important for people who are hungry when they wake up,”Johnstone says.“Each body starts the day differently—and those individual differences need to be researched more closely,”Spitznagel says.“A balanced breakfast is really helpful,but getting regular meals throughout the day is more important to leave blood sugar stable through the day,which helps control weight and hunger levels,”says Elder.“Breakfast isn’t the only meal we should be getting right.”36.According to one professor,obesity is related to a lack of basic awareness of nutrition and health.37.Some scientists claim that people should consume the right kind of food at breakfast.38.Opinions differ as to whether breakfast is the most important meal of the day.39.It has been found that not eating breakfast is related to the incidence of certain diseases in some countries.40.Researchers found it was a change in eating habits rather than breakfast itself thatinduced weight loss.41.To keep oneself healthy,eating breakfast is more important than choosing what to eat.42.It is widely considered wrong not to eat breakfast.43.More research is needed to prove that breakfast is related to weight loss or food intake.44.People who prioritise breakfasts tend to have lower calorie but higher nutritional intake.45.Many studies reveal that eating breakfast helps people memorise and concentrate. Section CDirections:There are2passages in this section.Each passage is followed by some questions or unfinished statements.For each of them there are four choices marked A), B),C)and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet2with a single line through the centre.Passage OneQuestions46to50are based on the following passage.Textbooks represent an11billion dollar industry,up from$8billion in2014. Textbook publisher Pearson is the largest publisher—of any kind—in the world.It costs about$1million to create a new textbook.A freshman textbook will have dozens ofcontributors,from subject-matter experts through graphic and layout artists to expertreviewers and classroom testers.Textbook publishers connect professors,instructors and students in ways that alternatives,such as open e-textbooks and open educational resources,simply do not.This connection happens not only by means of collaborative development,review and testing,but also at conferences where faculty regularly decide on their textbooks and curricula for the coming year.It is true that textbook publishers have recently reported losses,largely due to students renting or buying used print textbooks.But this can be chalked up to the excessively high cost of their books—which has increased over1,000percent since 1977.A restructuring of the textbook industry may well be in order.But this does not mean the end of the textbook itself.While they may not be as dynamic as an iPad,textbooks are not passive or lifeless. For example,over the centuries,they have simulated(模拟)dialogues in a number of ways.From1800to the present day,textbooks have done this by posing questions for students to answer inductively(归纳性地).That means students are asked to use their individual experience to come up with answers to general questions.Today’s psychology texts,for example,ask:“How much of your personality do you think you inherited?”while ones in physics say:“How can you predict where the ball you tossed will land?”Experts observe that“textbooks come in layers,something like an onion.”For an active learner,engaging with a textbook can be an interactive experience.Readers proceed at their own pace.They“customize”their books by engaging with different layers and linkages. Highlighting,Post-It notes,dog-ears and other techniques allow for further customization that students value in print books over digital forms of books.46.What does the passage say about open educational resources?A)They contribute to teaching as much as to learning.B)They don’t profit as much as traditional textbooks do.C)They can’t connect professors and students as textbooks do.D)They compete fiercely for customers with textbook producers.47.What is the main cause of the publishers’losses?A)Failure to meet student need.C)Industry restructuring.B)Emergence of e-books.D)Falling sales.48.What does the textbook industry need to do?A)Reform its structures.B)Cut its retail prices.C)Find replacements for printed textbooks.D)Change its business strategy periodically.49.What are students expected to do in the learning process?A)Think carefully before answering each question.B)Ask questions based on their own understanding.C)Answer questions using their personal experience.D)Give answers showing their respective personality.50.What do experts say about students using textbooks?A)They can digitalize the prints easily.B)They can learn in an interactive way.C)They can purchase customized versions.D)They can adapt the material themselves.Passage TwoQuestions51to55are based on the following passage.When we think of animals and plants,we have a pretty good way of dividing them into two distinct groups:one converts sunlight into energy and the other has to eat food to make its energy.Well,thosedividing lines come crashing down with the discovery of a sea slug(海蛞蝓)that’s truly half animal and half plant.It’s pretty incredible how it has managed to hijack the genes of the algae(藻类)on which it feeds.The slugs can manufacture chlorophyll,the green pigment(色素)in plants that captures energy from sunlight,and hold these genes within their body.The term kleptoplasty is used to describe the practice of using hijacked genes to create nutrients from sunlight.And so far,this green sea slug is the only known animal that can be truly considered solar-powered,although some animals do exhibit some plant-like behaviors. Many scientists have studied the green sea slugs to confirm that they are actually able to create energy from sunlight.In fact,the slugs use the genetic material so well that they pass it on to their future generations.Their babies retain the ability to produce their own chlorophyll,though they can’t generate energy from sunlight until they’ve eaten enough algae to steal the necessary genes,which they can’t yet produce on their own.“There’s no way on earth that genes from an alga should work inside an animal cell,”says Sidney Pierce from the University of South Florida.“And yet here,they do.They allow the animal to rely on sunshine for its nutrition.So if something happens to their food source,they have a way of not starving to death until they find more algae to eat.”The sea slugs are so good at gathering energy from the sun that they can live up to nine months without having to eat any food.They get all their nutritional needs met by the genes that they’ve hijacked from the algae.51.What is the distinctive feature of a sea slug?A)It looks like both a plant and an animal.B)It converts some sea animals into plants.C)It lives half on animals and half on plants.D)It gets energy from both food and sunlight.52.What enables the sea slug to live like a plant?A)The genes it captures from the sea plant algae.B)The mechanism by which it conserves energy.C)The nutrients it hijacks from other species.D)The green pigment inherits from its ancestors.53.What does the author say about baby sea slugs?A)They can live without sunlight for a long time.B)They can absorb sunlight right after their birth.C)They can survive without algae for quite some time.D)They can produce chlorophyll on their own.54.What does Sidney Pierce say about genes from an alga?A)They are stolen from animals like the sea slug.B)They can’t function unless exposed to sunlight.C)They don’t usually function inside animal cells.D)They can readily be converted to sea slug genes.55.What do we learn about sea slugs from the passage?A)They behave the way most plant species do.B)They can survive for months without eating.C)They will turn into plants when they mature.D)They will starve to death without sunlight.Part IV Translation(30minutes)Directions:For this part,you are allowed30minutes to translate a passage from Chinese into English.You should write your answer on Answer Sheet2.中国的家庭观念与其文化传统有关。
