2019-2020学年成都龙泉一中高三英语一模试题及答案
2019-2020学年成都龙泉一中高三英语一模试题及答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AChildren under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority (优先事项) . They should act in a socially responsible way toprovide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-name registration, thus making it impossible to put this policy in effect. Parents ly need to strengthen guidance andsupervision to keep their children from gaming addiction.1. What should kids do according to Andrew?A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2. What does Pink advise the gaming industry to do?A. Pay attention to its profit.B. Focus on kids’ health.C. Be responsible for kids’ surroundings.D. Persuade kids lo play more games.3. What role do parents have according to the passage?A. They keep hold of their phones.B. They set examples for their kids.C. They limit their kids’ time.D. They blame kids for addiction.BAvi Loeb, a scientist, believes that we are not alone in the universe. The belief fits withLoeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.Astronomers inHawaiifound the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinks it's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence thatcontradictshis beliefs, he will immediately give in.Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to the Israeli farming village where he grew up.4. What does Loeb say about “Oumuamua”?A. It is an icy comet.B. It looks like a long photo.C. It is actually some sort of rock.D. It may come from another alien civilization.5. What does the underlined word “contradicts” in paragraph 4 probably mean?A.Goes against.B. Relies on.C. Turns to.D. Searches for.6. What do you think of Loeb?A. He is foolish.B. He is unsatisfied with his titles.C. He is a firm believer in scientific truth.D. He is uncertain about his career future.7. What's the best title for the text?A. Have Aliens Paid a Visit in Spaceships?B. Do We Really Know about Space Theory?C. Scientists Are Working on High TechnologyD. Astronomers Are Encouraging Space TravelCThe Gata used to look annoyed when they received power bills that routinely topped $200. Last September the couple moved into a 1,500-square-foot home in Premier Gardens, an area of 95 “zero-energy homes” (ZEH) just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $75. For the past two months, they haven’t paid a cent.ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions (住宅开发项目) in California where every home cuts power consumption by 50%, mostly by using low power appliances and solar panels.Aside from the panels on the roof, Premier Gardens looks like a community of traditional homes. But inside, special windows cut power bills by blocking solar heat in summer and keeping indoor warmth winter.The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by “net metering”: they pay for the amount of power that they get from the grid, minus the kilowatts(千瓦) they feed into it. If a home generates more power than it uses, the bill is zero.That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. "It helps us lower usage at peak power times," says solar expert Mike Keesee. “That lets us avoid building costly plants or buying expensive power at peak usage time.”What’s not to like? Mostly the costs. The special features can add $25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be extremely expensive. For the consumer, it's a matter of paying now for the hardware to save later on the power bill.8. Why is the Gata eager to see their electricity bills now?A. They want to cut down their utility' expenses.B. They want to know if they are able to pay.C. They want to see how much they have saved.D. They want to avoid being overcharged.9. What is special about the ZEH communities?A. They are built in harmony with the environment.B. They have created cutting edge technologies.C. They are subdivided into half a dozen sections.D. They aim to be independent in power supply.10. What does the "net metering" practice mean to the power company?A. More pressure at peak timeB. Reduced operational costs.C. Increased electricity output.D. Less profits in the short term.11. The author believes that buying a house in a ZEH community __________.A. is a worthy investment in the long runB. is but a dream for average consumersC. gives the owner great tax benefitsD. contributes toenvironmental protectionDA nurse has fulfilled (实现) a promise she made to her patient four years ago to one day attend her daughter's graduation from nursing school.Edina Habibovic, 22, graduated from Chamberlain University's College of Nursing in 2020. Her mother, Sevala Habibovic, 46, died in2017 after a two year fight with breast cancer.“I thought the medical field wasn't for me. Then, my mom got sick and I had all the experience going in and out of the hospital, ” Edina toldGood MorningAmerica. “When my mom passed away, I thought, ‘I want to dothis.’”she said.Sanja Josipovic, who at the time worked as a home health nurse with Northwestern Medicine in Winfield, Illinois, cared for Sevala inside her home. They often chatted and shared the latest news with each other over six months of care.“She was most worried about Edina because she was young and hadn't finished school yet, ” Sanja said. “We are like sisters; we care about and trust each other. She was a powerful and strong minded woman. She wasn't scared to die; she was just worried about her kids and husband.”Edina said her mother lived for being with her family and taking care of people. “When Sanja was working, my mom would still try to make her something to eat, no matter how sick she was, ” Edina added. When Sevala's life was coming to an end, she asked Sanja to take her place at her youngest daughter's nursing school graduation. “That was the only thing she was going to miss. Edina's graduation, ” said Sanja, who is a mother of three herself. She agreed.Due to COVID -19, there was no graduation or pinning ceremony. Edina's manager at Marianjoy Rehabilitation Hospital decided to host a pinning ceremony for her and have Sanja present the pin. “Sanja has fulfilled her promise, ” Edina said.Edina and Sanja are now caring for patients alongside one another as colleagues at Marianjoy.12. What does the underlined word “this” in paragraph 3 refer to?A. Leaving the hospitalB. Working as a nurseC. Facing death positivelyD. Caring for Edina's mother13. What can be learned about Sanja and Sevala?A. They enjoyed volunteeringB. They were cancer survivorsC. They had unhappy marriagesD. They developed a close bond14. What would be Sevala's regret?A.

A reboot (翻拍) of the 1970s TV series, not to mention the two films from 2000 and 2003, the new version is directed by Elizabeth Banks.

Charlie’s Angels.BCycling has long been a sport where a competitive edge is pursued, often at any cost. Cycling shorts, however, were an area that technology had yet to enter. Little was added to them apart from, perhaps, some padding to protect a rider.Now, however, new cycling shorts are being equipped with sensors to help riders defeat opponents easily. A British start-up has created a pair of shorts that uses electric sensors and artificial intelligence to shape and strengthen cyclists' muscles while they are moving. It plans to also adapt this product next year for joggers and people at the gym.The shorts, created by Devon Lewis, a PhD student at theUniversityofSouthampton, are able to send out tiny electric currents into a user's muscles to improve their cycling technique. Mr Lewis, 27, came up with the idea after studying a connection between the brain and muscles that sends chemical signals from motor neurons to muscle fibres to make the muscle contract and strengthen.The shorts, created by Mr Lewis's start-up bypass this connection using electric cur rents to build muscle strength directly, without relying on the brain to send out signals. “We have a limited ability to control our muscles naturally,” Mr Lewis said. “You can control them more exactly, get more from your muscles and contract them more strongly, if you stimulate them directly with electricity.” Electric wires in the shorts send out currents that activate the muscle. “For those worried about getting a shock while cycling,” Mr Lewis said, “It's sort of the same thing as when you have spicy food and you get that little rush. It feels strange when you first start using it but then you adapt to it quite quickly.”His idea has received support from Future Worlds, a start-up accelerator atSouthamptonUniversity. The product is being shown next week at the technology conference CES, held digitally this year.4. What's the strength of the newly invented cycling shorts ?A. They help cyclists perform better.B. They last longer than normal ones.C. They can keep a balanced comfort.D. They have tools to make good figures.5. Why can the cycling shorts help the runners and joggers?A. They are made of quality cotton materials.B. They are created by world-top designers.C. They can make running or jogging less boring.D. They are made intelligently with electric sensors.6. What may be some people's worry about the shorts?A. They may spend more than they can afford.B. They get little help from the new shorts.C. They may get shocked by the electricity.D. The new shorts can't function well enough.7.What's the best title of the text?A. The Special CyclingShortsB. Waysto Be a Good RunnerC. How Shorts Benefit YouD. Some Tips about Running FastCJon Pedley is making a big change. He is giving up his life as a businessman for a life of helping others. He is trading his beautiful farmhouse in England for life in a mud hut in Uganda, East Africa.Pedley admits that he has notalways led a very positive life. At times he drank too much and got in trouble with the law. “I’ve always put the pursuit of money in front of everything else. As long as I was all right, I didn’t care who I was hurting, ” says Pedley.But a visit to Uganda in 2007 gave Pedley a new outlook on life. He was amazed at what he saw and how much the people there appreciated the work he was doing. “I worked there for a few days and these people who have nothing were thanking me by giving me bags of potatoes, which are a fortune for them,” he said.Now Pedley is selling his business, his $1.5 million farmhouse, and his expensive car — and moving into a hut made of mud and boards in a small Ugandan village. There he will help run an organization that hopes to improve the quality of life for people in the village of Kigazi. He will help to build schoolrooms for children and tanks to hold clean water for villagers. Today, people in Kigazi must walk two miles to a hospital, so Pedley will help to build doctors’ offices, too.Pedley’s organization will also work with English teenagers who are in trouble. The teens will be sent to a “camp” in Uganda that Pedley will run. The teens will live in mud huts and help to build water, health, and education facilities for kids in Kigazi, many of whom have lost their parents to poverty or disease. Pedley hopes the teens will see a side of life that might help them turn around their own lives and set them on a new and more positive path.8. Which of the following best describes Pedley’s life in the past?A. Negative.B. Colorful.C. Independent.D. Selfish.9. What will Pedley do in the small Ugandan village?A. Do business with the local people.B. Help farmers increase potato output.C. Assist villagers with construction work.D. Introduce tools to improve English teaching.10. Why will Pedley work with English teenagers in trouble?A. To encourage them to make friends with locals.B. To inspire them to live a more positive life.C. To train them to become doctors in the future.D. To make them learn about different cultures.11. What is the best title for the text?A. From millionaire to mud hutB. A life-changing adventureC. A rich man becoming homelessD. More money, more worriesDIn the northern part ofAustin there once lived an honest family by the name of Smothers. The family had John Smothers, his wife and their five-year-old daughter.One night after supper the little girl was ill with a serious stomachache, and John Smothers hurried downtown to get some medicine. He never came back. The mother was very sad over her husband's disappearance, and it was nearly three months before she married again, and moved to San Antonio. The little girl recovered and in time grew up to womanhood. After a few years had rolled around, the little girl also married in time, and she also had a little girl of five years. She still lived in the same house where theydweltwhen her father had left and never returned.By an unbelievable coincidence her little girl was taken with the same stomachache on the same night of the disappearance of John Smothers, who would now have been her grandfather if he had been alive. “I will go downtown and get some medicine for her,” said John Smith(for it was he whom she had married). “No, no, dear John,” cried his wife. “You, too, might disappear forever, and then forget to come back.” So John Smith did not go, and together they sat by the bedside of little Pansy. After a little while Pansy seemed to grow worse, and John Smith again wanted to go for medicine, but his wife would not let him.Just then, the door suddenly opened and an old man with long white hair entered the room. “Hello, here is grandpa,” said Pansy. She had recognized him before any of the others. The old man drew a bottle of medicine from his pocket and gave Pansy a spoonful. She got well immediately. “I was a little late,” said John Smothers, “as I waited for a street car.”12. What happened after John Smothers disappeared?A. His daughter took some medicine.B. His wife left for San Antonio.C. Pansy immediately had a stomachache.D. John Smith went for medicine.13. What does the underlined word “dwelt” in paragraph 2 probably mean?A. Lived.B. Left.C. Returned.D. Married.14. What is the relationship between John Smothersand Pansy?A. Husband and wife.B. Father and daughter.C. Grandfather and granddaughter.D. Father and son.15. How could Pansy's mother feel when she saw John Smothers?A. Worried.B. Sad.C. Uninterested.D. Surprised.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

He has played in almost every major city. He has won many Grammy awards for his recordings. He has also won Emmy Awards for his work on television.Itzhak Perlman suffered from polio (小儿麻痹症) at the age of four. The disease damaged his legs. He uses a wheelchair or walks with the aid of crutches (拐杖) on his arms. But none of this stopped him from playing the violin. He began as a young child. He took his first lessons at the Music Academy of Tel Aviv. Very quickly, his teachers recognized that he had a special gift.At thirteen he went to the United Sates to appear on television. His playing earned him the financial aid to attend theJuilliardSchoolinNew York. In 1964 Itzhak Perlman won the Leventritt Competition in that city. His international fame had begun.His music is full of power and strength. It can be sad or joyful, loud or soft. But critics (评论家) say it is not the music alone that makes his playing so special. They say he is able to communicate the joy he feels in playing, and the emotions that great music can deliver.Anyone who has attended a performance by Itzhak Perlman will tell you thatit is exciting to watch him play. His face changes as the music from his violin changes. He looks sad when the music seems sad. He smiles and closes his eyes when the music is light and happy. He often looks dark and threatening when the music seems dark and threatening.4. According to the passage, what do we know about Itzhak Perlman?A. He is 75 years old today.B. He was born inNew York City.C. He has some achievements in music.D. He was a rich citizen of the world.5. When Itzhak Perlman first learned music, his teachers ________.A. ignored his talentsB. thought he was fit to learn musicC. had pity on himD. didn't want to accept him6. What makes Itzhak Perlman's playing special according to critics?A. The emotions he communicates in his playing.B. The style in which he plays his music.C. The kind of music he plays.D. The power and strength in his music.7. How do people feel when they hear Itzhak Perlman play?A. Moved.B. Calm.C. Funny.D. Excited.CThe AI research arm of Alibaba created a machine learning model that received a higher score on the Stanford Question Answering Dataset than humans. The database consists of more than 100,000 questions to test reading comprehension.In early January this year the Alibaba AI software machine scored 82.44 on the test while humans scored 82.304. Besides, computers and AI have already defeated humans, for example in games such as chess. However, it seemed that language skills were superior in humans as machines find languages hard to master.A large number of call center employees, often in developing countries, may be out of work soon if the AI robots are cheaper and as effective as human labor. Soon when you phone a company for information the conversation will go like this: “ We are sorry but all our robots are busy right now. We value your call. Please stay on the line until a robot is free to serve you. There are just 12 callers ahead of you.” A robot will serve you some popular tunes while you wait.Si Luo, who is a chief scientist of natural language processing at Alibaba’s AI research group noted that questions such as “What causes rain?” can now be answered with a high degree of accuracy by robots. Si Luo said, “ We believe the foundational technology can be gradually applied to a lot of applications such as customer service, museum tutorials, and online responses to inquiries from patients, freeing human efforts in a new way.”Si Luo’s team is working closely with Ali Xiaomi, a mobile customer service chatbot. Ali Xiaomi can be customized to be used on Alibaba’s platforms such as Taobao and Tmall. The new AI robots could answer consumers’ questions as they did the Stanford questions. The robots would look for the answers from prepared information. However, there are limits to what the system will be able to do. If questions do not have clear-cut answers, or the questions asked are too unclear or ungrammatical, the robot may not be able to deal with them. 8. What can we learn about the Alibaba AI software machine?A. It has been tested in some areas.B. It has become popular since January.C. It has offered a special learning style.D. It has made people interested in reading.9. What does the example in paragraph 3 show about the AI robots?A. They should have better language skills.B. They may replace humans in some fields.C. They need to be customized to serve customers.D. They will be widely used in developing countries.10. How does Si Luo feel about the foundational technology?A. Doubtful.B. Worried.C. Curious.D. Confident.11. What can we infer from the lastparagraph about Ali Xiaomi?A. It needs to improve in some ways.B. It is connected with another system.C. It is a platform to show good service.D. It can answer any questions accordingly.DHardware in general,and smartphones in particular,have become a huge environmental and health problem in the Global South's landfill sites(垃圾填埋场).Electronic waste(e-waste) currently takes up 5 percent of all global waste,and it is set to increase rapidly as more of us own more than one smartphone,laptop and power bank They end up in places like Agbogbloshie on theoutskirts of Ghana's capital,Accra. It is the biggest e-waste dump in the world,where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process.They risk their health searching for the precious metals that are found in abandoned smartphones.But Agbogbloshie should not exist.The Basel Convention,a 1989 treaty,aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries.The e-waste industry,however,circumventsregulations by exporting e-waste labelled as "secondhand goods' to poor countries like Ghana,knowing full well hat it is heading for a landfill site.A recent report found Agbogbloshie contained some of the most dangerous chemicals.This is not surprising: smartphones contain chemicals like mercury（水银）,lead and even arsenic(砷).Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certainchemical which can cause cancer and damage the immune system at a level that's about 220 times greater than a limit set by the European Food Safety Authority(EFSA).Most worryingly,these poisonous chemicals are free to pollute the broader soil and water system.This should concern us all, since some ofGhana's top exports are cocoaand nuts.Some governments have started to take responsibility for their consumers' waste.For example,Germanyhas started a project that includes a sustainable recycling system at Agbogbloshie,along with a health clinic for workers.However,governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware,especially when governments' green policies are focused on issues like climate change.Only the manufacturers can fix this.A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable,or at least cost-neutral12. What can we infer from Paragraph 2?A. Electronic waste requires more landfill sites acrossGhana.B. Electronic waste is too complex to get fully recycleC. Electronic products need to be improved urgentlyD. Electronic pollution is a burning question in Agbogbloshie13. What does the underlined word "circumvents"in Paragraph 3 mean?A. AbolishesB. TightensC. Brings inD. Gets around14. What should be the best concern according to the text?A. The thread of polluted food around the worldB. The damage of chicken’s immune systemC. The lack of diversity inGhana's exportsD. The violation of EFSA's standards15. What does the author think is the best solution to the e-waste problem?A. Manufacturers' developing a sustainable hardware economyB. Governments’ adjusting their green policies about e-waste.C. Reducing customers' demands for electronic productsD. Manufacturers’ urging the government to make effective policies to ensure more profit.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年成都龙泉一中高三英语模拟试卷及参考答案
2019-2020学年成都龙泉一中高三英语模拟试卷及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn theUnited States, the word "holiday" is synonymous with celebration. The following tenholidaysper year are proclaimed by the federal government.Independence DayIndependence Day is annually celebrated on July 4 and is often known as "the Fourthof July”. It is the anniversary of the publication of the declaration of independence fromGreat Britainin 1776. Now it is celebrated in all the states. The army marks the occasion by firing a 13-gun salute every year. Ceremonies may include parades, official speeches, visits to historic monuments and fireworks displays.Memorial DayThis holiday, on the fourth Monday of every May, is a day on which Americans honor the dead. Originally a day on which flags and flowers were placed on graves of soldiers who died in the American Civil War, now it has become a day on which the dead of all wars and all other dead are remembered the same way.Veterans DayVeterans Day was established to honor Americans who had served in World War I. It falls on November 11, the day when that war ended in 1918, but it now honors veterans of all wars in which the United States has fought Veterans' organizations hold parades or other special ceremonies, and the US president customarily places a wreath on the Tomb of the Unknowns at Arlington National.ThanksgivingThanksgiving Day is celebrated on the fourth Thursday in November. It has been an annual tradition in theUnited Statessince 1863. Today, people celebrate Thanksgiving to remember these early days. The most important part of the celebration is a traditional dinner. Thanksgiving dinner almost always includes some of the foods served at the first feast: roast turkey, cranberry sauce potatoes pumpkin pies. Before the meal begins, families often pause to give thanks.1. When isIndependence Day?A. May 14，B. July 13.C. July 14.D. July 4.2. Which holiday honors dead soliders?A. Independence Day.B. Memorial Day.C. Veterans Day.D. Thanksgiving.3. What will Americans do on Thanksgiving Day?A. They say thanks.B. They havefriend gatherings.C. They go on holiday.D. They buy many cards.BIt might have been Jimmy Kimmel, or any other sharp-tongued talk show hosts of late-night TV. In this instance, it was Samantha Bee, stating her opposition to childhood vaccinations humorously. “Who are you going to believe?” she asked. “Leading authorities on medical science, or 800 comments on your cousin’s Facebook page?”Joking about science can have serious effects, according to studies by communication scholars. Accordingly, since 2013, Paul, a psychological professor, has conducted studies of how satire (讥讽) can influence people’s beliefs about science, which have shown that if you want to interest people in science and shape their views on hot-button science issues, satirical humor can work better.Many Americans pay little attention to science. Even people who regularly watch TV news receive only scraps of science information in their media diet, because mainstream media outlets devote so little airtime to the subject. On top of that, some Americans may regard science as inaccessible.Yet satirical humor can reach viewers who would never watch NOVA or read — well, National Geographic. Millions of people watch late-night television programs live, and videos of these shows get millions of views on streaming services. In 2016, a vote conducted by the University of Delaware Center indicated that nearly one in 10 said they learned about science from late-night television shows.Late-night hosts may occasionally poke fun at scientists. More often, however, the hosts promote a positive image of science. By making science entertaining to audience with little knowledge of the topic, late-night television could spark science engagement. Furthermore, the researchers concluded that satirical shows had the biggest impact among the least educated viewers, thus helping to narrow a gap in attention to science. Though late-night satirical humor can boost science interest and awareness, it has its limits. Science is complex, and conveying that complexity in a few minutes while telling jokes can be a challenge.4. What does Paul’s studies of joking about science indicate?A. It may do serious damage to science.B. It can effectively popularize science.C. It totally changes people’s attitude to science.D. It will shift people’s attention from entertainment to science.5. Why do TV watchers receive a little science information?A. Because they enjoy watching entertainments.B. Because science is not easy to come up with.C. Because they find no interest in science issues.D. Because science is scarcely seen on mainstream media.6. What do we know about the late-night shows involving science?A. The hosts get used to playing tricks on scientists.B. The hosts’ aim is to build a positive image of science.C. Education gap can be bridged through late-night shows.D. Science participation can be promoted among their viewers.7. What’s the author’s attitude towards combining science with satire?A. Critical.B. Objective.C. Positive.D. Negative.CMark Twain,the famous American writer,was once traveling in France.He went by trainto Dijon.He was very tired and wanted to sleep.He therefore asked the conductor to wake him up when the train came to Dijon.But first he explained he was a very heavy sleeper,“I may possibly protest(抗议)loudly when you try to wake me up,” he said to the conductor.“But don’t take any notice of what I say.Just put me off the train anyway.”Then Mark Twain went to ter,when he woke up it was night time and the train had reached Paris already.He realized at once that the conductor had forgotten to wake him up at Dijon.He was so angry that he ran to the conductor and began to shout at him.“I have never been so angry in my life,” Mark Twain said.The conductor looked at him calmly(平静地).“You are not half so angry as the American whom I put off the train atDijon,” he said.8. Mark Twain knew that he was a heavy sleeper,so ________.A. he protested loudly to the conductorB. he did not sleep before he arrived inDijonC. he told the conductor to wake him up no matter how loudly he might protestD. he slept lightly that time9. The conductor didn’t wake up Mark Twain atDijonbecause ________.A. he didn’t take Mark Twain’s words seriouslyB. he forgot Mark Twain’s words when the train came toDijonC. he did not want to bear his protestD. he mistook another American traveler for Mark Twain10. The American whom the conductor put off the train ________.A. did not want to get off atDijonB. wanted to get off atParisC. wanted to get off atDijonD. did not want to get off atParis11. Which of the following is TRUE?A. The conductor didn’t take Mark Twain’s words seriously.B. The conductor did take Mark Twain’s words seriously.C. The conductor was a heavy sleeper.D. Mark Twain must get off atParis.DThe world's largest iceberg is floating toward South Georgia in the southernAtlantic Ocean. Scientists fear the iceberg could crash into the island and block major feeding areas for a large population of penguins and seals. If the iceberg hits the island, it could prevent the penguins and seals from reaching food supplies.The huge iceberg is named A68a. It broke away fromAntarctica's Larsen C Ice Shelf in 2017. Satellite images show the iceberg has remained in one piece. It is estimated to be about 150 kilometers long and 48 kilometers wide. It is traveling at one kilometer per hour and is on a path to hitSouth Georgiain around 30 days.This is the time of year when seals and penguins spend a lot of time caring for their young. The distance that parents have to travel to find food is crucial. That means they have to go a lot further or go around the iceberg to find sources of food.Ecologists say an iceberg crash would also disturb materials settled on the seabed, possibly polluting the surrounding seas. As the iceberg melts, it would also release large amounts of fresh water into the ocean. This could affect krill（磷虾）populations that are a major source of food for the island's wildlife. The iceberg could remain for up to 10 years and change the area's whole ecosystem. These are globally significant populations ofthese species. If these species fail in this particular area, then the numbers globally are going to go down quite dramatically.Professor Geraint Tarling, an ecologist at the British Antarctic Survey, said, "The breaking off of icebergs fromAntarcticais a natural process. But the process is changing with climate change. What we're seeing with models and some observations now is that this is happening at an increasing rate. And so, this might become more of a usual thing in the future."12. Why are the scientists worried about the coming iceberg crash?A. It will bring extremely cold weather.B. It will destroy the feeding areas of the animals.C. It will put wildlife on the island at risk of starving.D. It will prevent animals from moving to other places.13. What is paragraph 2 mainly about?A. The characteristic of the iceberg.B. The importance of the iceberg.C. The traveling speed of the iceberg.D. The forming process of the iceberg.14. What damage can an iceberg crash bring according to paragraph 4?A. Using up much fresh water.B. Polluting the surrounding farms.C. Changing the world's ecosystem.D. Affecting the number of certain species.15. How does Tarling think of the breaking off of icebergs fromAntarctica?A. It may slow down in the near future.B. It may become common in the future.C. It has a great influence on the climate.D. It helps scientists conduct a sea study.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。
