The bottle is27 , and the label says “pure water”, but maybe what’s inside is not so28 . 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 recently30 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 21 degrees 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 Hurrican e 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. Thevideo 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 agen cy’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 in frastructure 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 MikeSwigart told me, “because we’re in literally every community in this country … We’re obligated to d eliver 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 $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebu ild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving, prosperous,” he said.[K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ 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 G oel 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 enga ging, 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 researc hers’ 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 rece nt 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.

China showed off its Mars spacecraft during a landing test last week in the northern province of Hebei. China is planning to send a lander and rover to Mars next year to explore parts of the red planet. The United States and European space agency are also sending rovers to the planet in 2020, and the United Arab Emirates plans to launch an orbiter. Officials say the Mars lander successfully passed a hovering-and-obstacle avoidance test. The landing area had small piles of rocks on the ground, similar to what the uneven surface on Mars is like. The lander will have to move around on this kind of surface when it gets to the planet. In 2016, China officially began the Mars exploration mission work, and currently all of the different development work is progressing smoothly. China has developed a powerful rocket, the Long March 5, to send the spacecraft to Mars in 2020. The trip to the plant will last about seven months. But landing on it will take only about seven minutes. The landing will be the most difficult part of the space flight. Many spacecrafts sent to Mars have been lost or destroyed over the years. Only the U.S. space agency NASA has been successful, with eight landings. China's space program plans to use a Long March 5 rocket to send a spacecraft to the Moon by the end of this year, or early next year. The Chang'e-5 spacecraft will bring back pieces of rock from the moon's surface. Last January a Chang'e-4 probe successfully touched down on the far side of the moon. While NASA sent humans to the moon, this was the first time for a probe to touch down on the lesser-known far side. The landing was a major success for China's space program. China first landed a spacecraft on the moon in 2013.
