2019-2020学年长沙铁路第一中学高三英语上学期期中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ASevenhugs HugOneDo you want to improve the quality of your sleep? Sevenhugs has created HugOne that tracks different sleep patterns to help families consistently rest better. There are dozens of devices and tools devoted to monitoring the sleep. But, HugOne is the world’s first family smart home sleep system, which integrates a calculation rule for sleep patterns of children and adults.HugOne is a well-designed product, full of a sense of science and technology. It connects to a number of smaller sensors called “minihugs”, which are placed on the edge of each bed. They monitor the sleep patterns and other data coming from the person sleeping in that bed. The data arethen sent to an app on the smartphone.● The benefits of HugOne include:* Having a smart alarm clock on the app as HugOne learns your sleep cycle and automatically sets and sounds to when the best moment in your sleep cycle is identified.* Monitoring temperature and humidity in your bedroom as well as indoor air quality for the main living space.* Linking with smart lamps and thermostats, allowing users to fall asleep with sunset light and preferred nighttime temperatures, and wake up to sunrise light and preferred daytime temperatures.* Ensuring safety from electronic transmissions when you sleep-when the minihug senses a presence in bed, it shuts off its electronic transmissions and starts recording sleep data and sending them to the app.● The following are selected from customers’ comments:I prefer HugOne, since it’s convenient to use. I simply place the minihug in the corner of my bed under the sheet and it goes to work monitoring my sleep cycle. It’s really good.—Robert Compton● HugOne available for purchase includes:I think HugOne is a humanized product. It’s shareable, and I’ve connected eight minihugs to the HugOne base in my house. All my family members think highly of it.—Chris HanawaltHugOne will provide maximum protection for your sleep. If you want to get more detailed information, please call the sellers at 1-800-576-1899 or .Style: Sleep Tracking System＋2 Sleep SensorsColour: Blue＋Rose1. How does HugOne effectively work?A. It controls sleep patterns automatically.B. It creates smart systems for a better sleep.C. It collects sleep data through the minihugs.D. It makes a calculation of the data sensors need.2. According to the passage, HugOne can ______.A. adjust temperature, humidity and air quality in bedroomsB. update the sleep cycles by aid of an alarm clock on the appC. record sleep data when there are electronic transmissions in bedD. help users fall asleep and wake up naturally with preferred temperatures3. The passage is made more believable by ______.A. providing statisticsB. drawing a comparisonC. giving a demonstrationD. using recommendationsBLife in the Internet age is lonely—or is it? That’s what experts in human interaction are debating after a new Stanford University survey has been published.According to the study, the more time people spend online, the less they can spare for real-life relationships with family and friends. The researchers asked 113 people about the Web’s influence on daily activities. 36％of those people are online for more than five hours a week.” As Internet use becomes more widespread, it will have an increasingly isolating (孤立的) effect on society,” says Robert Kraut, one of the researchers.Scholars and Web lovers criticized the study for stretching its data to make the “isolating” point. While 13％of regular Web users admitted the loss of time with loved ones, 60％reported watching less TV. The survey also shows that E-mail is the most popular online activity. If some of webheads (网虫)spend what was once passive TV time keeping company with friends via E-mails, “that’s a move toward greater connectedness,” says Paul Resnick, a professor at the University of Michigan.Thisisn’t the first claim that the Web should be criticized. A 1998 report monitored 73 Pittsburgh-areafamilies’ Net use for a year. People who used the Internet more “talked less to family members and reported being lonelier and more depressed.” says Robert Kraut.“It’s true that there have been big declines in social connectedness over the past decades, but those declines began before the Internet was invented,” says Thomas Putnam.As Amitay Etzioni says, the Internet gives us a different kind of social life—not better or worse than before, but just different.4. Who claimed that the Web had negative influence?A. Paul Resnick.B. Robert Kraut.C. Thomas Putnam.D. Amitay Etzioni.5. The underlined word “This” in Para.4 refers to .A. the opinion expressed in Bowling AloneB. the survey made by the University of MichiganC. the conclusion in a report written in 1998D. the study conducted by Stanford University6. From the passage we learn that .A. watching TV used to take time away from staying onlineB. the Web was blamed more than once for causing an isolating effectC. 36％ofweb users spend more than five hours a week onlineD. the Web has the same influence as telephones and televisions7. The passage mainly discusses .A. how we can make a better use of the InternetB. how declines in social connectedness appearC. whether the Internet causes an isolating effectD. what a different life the Internet brings to usCWolves have a certain undeserved reputation: fierce, dangerous, good forhunting down deer and farmers’ livestock. However, wolves have a softer, more social side, one that has been embraced by a heart-warming new initiative.In a bid to save some of Europe’s last wolves, scientists have explored the willingness of these supposedly fierce creatures to help others of their kind. Female wolves, the scientists have discovered, make excellent fosterparents to wolf cubs that are not their own. The study, published in Zoo Biology, suggests that captive-bred wolfcubs(幼兽)could be placed with wild wolf families, boosting the wild population.The gray wolf was once the world’s most widely distributed mammal, but it became extinct as a result of widespread habitat destruction and the deliberate killing of wolves suspectedof preying on livestock. Fear and hatred of the wolf have since become culturally rooted, fuelled by myths, fables and stories.In Scandinavia, the gray wolf is endangered, the remaining population found by just five animals. As a result, European wolves are severely inbred and have little geneticvariability（变异性）, making them vulnerable to threats, such as outbreaks of disease that they can’t adapt to quickly. So Inger Scharis and Mats Amundin of Linkoping University, in Sweden, started Europe’s first gray wolf-fostering program. They worked with wolves keptat seven zoos across Scandinavia. Eight wolf cubs between four and six days old were removed from their natural parents and placed with other wolf packs in other zoos. The foster mothers accepted the new cubs placed in their midst.The welfare of the foster cubs and the wolves’ natural behavior were monitored using a system of surveillance cameras. The foster cubs had a similar growth rate as their step siblings in the recipient litter, as well as their biological siblings in the source litter. The foster cubs had a better overall survival rate, with 73% surviving until 33 weeks, than their biological siblings left behind, of which 63% survived. That rate of survival is similar to that seen in wild wolf cubs. Scientists believe that wolves can recognize their young, but this study suggests they can only do so once cubs are somewhere between three to seven weeks of age.If captive-bred cubs can be placed with wild-living families, which already have cubs of a similar age, not only will they have a good chance of survival, but they could help dramatically increase the diversity of the wild population, say the researchers. Just like the wild wolves they would join, these foster cubs would need protection from hunting. Their arrival could help preserve the future of one of nature’s most iconic and polarizing animals.8. What’s the theme of the passage?A. Giving wolf cubs a new lifeB. Foster wolf parents and foster cubsC. The fate of wild wolvesD. Changing diversity of wild wolves9. Which of the following flow chart best demonstrates the relationship between the wolves?A. B.C. D.10. Which of the following statements is true?A. Female wolves are willing to raise wolf cubs of 3 to 7 weeks old.B. Foster cubs are accepted by foster parents and are well bred.C. Man’s hostile attitude towards wolves roots in myths, fables and stories.D. Foster cubs and their biological siblings have similar growth rate and survival rate.11. What’s the purpose of the research?A. To help wolves survive various threatsB. To improve wolves’ habitat and stop deliberate killingC. To save endangered wolves by increasing their populationD. To raise man’s awareness of protecting wolvesDNewspapers in Great Britainvarygreatly in their ways of carrying the news. There are serious papers for those who want to know about important happenings everywhere, both at home and abroad. There are popular newspapers for those who prefer entertainment to information.The London newspaper that is best known outside Great Britain is probably the Times. It began in 1785, and has a high reputation for believable news and serious opinions on the news. It calls itself an independent paper, which means that it does not give its support to a particular political party. Its leading articles give the opinions of the editors, not those of the owners of the paper.Letters to the editor are printed in the newspaper. These parts of the Times are always interesting. Most of the letters are serious subjects. But from time to time there will be long letters on the subject which is not at all serious, perhaps on a new fashion of dress, or the bad manners of the young people, compared with manners ofthirty years ago.12. If you want to get pleasure, please buy yourself _________.A. a serious newspaperB. foreign newspaperC. any independent paperD. a popular newspaper13. The Times has been famous to outside Great Britain for ________ years.A. 19B. 85C. 236D. 22914. The Times is an independent paper because ________.A. it supports no political partiesB. it is not controlled by the British GovernmentC. it gives special support to all the political parties.D. the editor’s opinions are not examined by the owners of the paper15.

2019-2020学年长沙铁路第一中学高三英语上学期期中试卷及答案解析第一部分阅读（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AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BByteDance（字节跳动）Group’s TikTok, an overseas version of Chinese short video sharing app Douyin, faces an existential crisis in the United States, as murmurs of a “crackdown”（强制取缔）from the White House forced the Chinese company toengage in talks on selling its US business to Microsoft.TikTok is the fastest-growing registered global mobile internet app, with more than 100 million users, and its rapid growth, especially in the US, is seen as a threat to Facebook. The US government has long viewed globally competitive Chinese high-tech companies including Huawei as a threat and done whatever it could to crack down on（打击）them in the name of “national security”.The US government has not introduced any specific policy against TikTok only threatened it through a number of unclear statements.According to the latest media reports, Microsoft is prepared to press ahead withthe negotiations to take over TikTok’s US operations and complete the negotiations by Sept 15, following talks between Microsoft CEO Satya Nadella and US President Donald Trump.This means that TikTok will have to hand its fate over to some unpredictable power, and even have to sell its assets without the option of setting a price.The US government has failed to find a reasonable legal excuse to deal with TikTok. All private data of TikTok’s US users are stored in the US and are unlikely to be transferred. Considering the US government is trying to deal with TikTok in a political way, TikTok should consider incorporating（合并）the dispute into the US legal process to assert（坚持）its legal rights and interests.TiKTok’s core value lies in its unique algorithms,a product of artificial intelligence that represents the expertise of Chinese engineers and programmers with high-value intellectual property.The US government’s move, which has forced ByteDance to sell TikTok to a US company, is similar to a forcedtechnology transfer and an example of the US’ openseizureof Chinese intellectual property.If ByteDance sells TikTok to a US company for “security reasons", that would set a dangerous precedent, motivating other countries where TikTok operates to follow the US administration's example and cause a chain reaction.ByteDance is a young Chinese private company that cannot deal with a political game played by the US. But as a Chinese company that has gone global, ByteDance has reasons to take up legal means to defend its legal rights. The Chinese government can also consider examining whether the technology transfer in the deal violates China’s law and harms the country’s national interests.4. What is the most valuable as for TikTok?A. Its global popularity.B. Its artificial intelligence.C. Its registered global mobile internet app.D. Its private data of TikTok’s worldwide users.5. Why does the American government force the Chinese company to hand over TikTok’s US operations to a US company?A. Out of so-called political reasons.B. Out of so-called debt reasons.C. Out of so-called technical reasons.D. Out of so-called security reasons.6. What does the underlined word “seizure”probably mean in Para. 8?A. An untrue spoken statement about someone.B. The use of legal authority to take sth from sb.C. The crime of stealing sth from a person or place.D. The act of trying to hurt somebody using physical violence.7. What can be the best title for the news report?A. TikTok must defend its rights legallyB. TikTok is seen as a threat to FacebookC. ByteDance has to sell TikTok to a US companyD. ByteDance agrees to transfer technologyCA growing body of research is revealing associations between birth defects (缺陷) and a father's age, alcohol use and environmental factors, say researchers atGeorgetown University Medical Center. They say these defectsresult from epigenetic changes that can potentially affect multiple generations.The study, published in theAmerican Journal of Stem Cells, suggest both parents contribute to the health status of their offspring — a common sense conclusion which science is only now beginning to demonstrate, says the study's senior investigator, Joanna Kitlinska, PhD, an associate professor in biochemistry, and molecular and cellular biology.“We know the nutritional, hormonal and psychological environment provided by the mother permanently influences organ structure, cellular response and gene expression in her offspring,” she says.“But our study shows the same thing to be true with fathers — his lifestyle, and how old he is, can be reflected in molecules that control gene function,” she says. “In this way, a father can affect not only his immediate offspring, but future generations as well.”For example, a newborn can be diagnosed with fetal (胎儿的) alcohol spectrum disorder (FASD), even though the mother has never consumed alcohol, Kitlinska says. “Up to 75 percent of children with FASD have biological fathers who are alcoholics, suggesting that preconceptual paternal alcohol consumption negatively impacts their offspring.”Advanced age of a father is correlated with elevated rates of certain diseases, and birth defects in his children.A limited diet during a father’s preadolescence has been linked to reduced risk of cardiovascular death in his children and grandchildren. Paternal obesity is linked to enlarged fat cells, changes in metabolic regulation, diabetes, obesity and development of brain cancer. Psychosocial stress on the father is linked to defective behavioral traits in his offspring. And paternal alcohol use leads to decreased newborn birth weight, marked reduction in overall brain size and impaired cognitive function.“This new field of inherited paternal epigenetics needs to be organized into clinically applicable recommendations and lifestyle alternations,” Kitlinska says. “And to really understand the epigenetic influences of a child, we need to study the interplay between maternal and paternal effects, as opposed to considering each in isolation.”8. What’s the message the writer conveys in the passage?A. Both parents contribute to the health status of their offspring.B. Father’s age and lifestyle are tied to birth defects.C. Father plays a more critical role in birth defects.D. Birth defects can potentially affect multiple generations.9. What can we infer from the example in Paragraph 5?A. FASD can only be diagnosed in a newborn whose father is addicted to alcohol.B. A newborn will not contract FASD if his mother has never consumed alcohol.C. A father’s lifestyle can negatively impact his offspring.D. Most children have biological fathers who are alcoholics.10. Which of the following situations is less likely to lead to children’s birth defects?A. Having a father with a limited diet.B. Having a father who is an alcoholic.C. Having an overweight father.D. Having a father with psychosocial stress.11. What will the research probably continue to focus on in the part that follows?A. The maternal epigenetic influences of a child.B. The ways to avoid negative paternal influence on children.C. The clinical application of the research findings.D. The interaction between maternal and paternal effects.DThe herd of elephants moving north after leaving the Xishuangbanna National Nature Reserve in Yunnan province has drawn widespread public attention, with tens of millions of people following its movement on TV programs and social media platforms.But this is not because it’s the first time wild Asian Elephants have wandered away from their habitat and headed northward, but for only this time the herd has traveled more than 400 kilometers as far as Kunming. Photographs, videos and stories of the herd’s movement have sparked widespread discussions even overseas.However, there is a need to go behind the “cute photos” and the seemingly “fantastic” event and identify the reasons why wild elephants are leaving their habitat, and find ways to establish harmonious human-animal relationship within habitats and the surrounding forests and human settlements. It is important to scientifically mark the limits of the habitats for elephants and other animals in Xishuangbanna and elsewhere in the country for ecological reasons as well.Planting trees is a key and fundamental step toward restoration of nature. Yet long-term investment and a more scientific approach are needed to maintain the remaining forests as well as to extend the forest cover and strengthen conservation.Nevertheless, tree cover alone doesn’t mean a suitable habitat for all animals, for different species need different types of vegetation to survive and breed. The elephant herd in Yunnan is a reminder that we have to scientifically conserve the existing forests and turn them into suitable habitats for different species of animals andbirds, which will ultimately benefit humans.More ambitious targets should be set to rebuild or improve the food chain, and measures taken to ensure forest resources help wildlife flourish, in order to establish a harmonious human-animal relationship.Forests around the globe are still shrinking, particularly those in tropical and developing countries. The next decade therefore will be extremely important for the world’s forests and wildlife, and China can play a leading role in saving them by better protecting its forests and expanding its forest cover.12. Why has the herd of elephants caused so much public interest?A. There exist heated discussions in the whole country even overseas.B. TV programs and social media platforms want to benefit from them.C. They are the first wild Asian Elephants to leave their natural habitat.D. The elephants has traveled a long distance and lived in harmony with humans.13. What can we infer from the third paragraph about the “fantastic” event?A. More research on the reasons behind the event is required.B. Scientists need to limit the habitats for elephants and other animals.C. People should find ways to have a good relationship with elephants.D. There’s an urgent demand for detailed information about the elephants.14. Which method is provided in the passage to restore nature?A. Expanding the coverage of forest.B. Getting the government’s policy support.C. Bringing up various ways to protect the forests.D. Offering more kinds of vegetation to all animals.15. What does this event of elephants leaving their habitats remind us to do?A. To set more goals to change the food chain.B. To be aware of the situation of the existing forests.C. To realize harmonious coexistence of human and nature.D. To reduce the destruction of the forests around the globe.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学年长沙铁路第一中学高三英语上学期期中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AThe last thing Caitlin Hipp would have expected as she prepared to turn 28 years old was to be living at homewith her parents. But through working as a part-time skating instructor and restaurant server, she isn't able to earn enough to live anywhere other than home.To some degree, multigenerational households have always been a part of American life. However, the number of young adults who have been moving back in with their parents — or never leaving home in the first place — has been growing steadily.UBS Financial Services released a report that even suggests one reason for the growing number of young adultsstill living at home could be that their family doesn't want them to leave.The report shows that 74 percent of millennials (千禧一代)get some kind of financial support from their parents after college. It finds that millennials have redefined the ties that connect parents and children. Millennials see their parents as peers,friends and instructors. Nearly three quarters talked with their parents more than once a week during college. In return, their parents happily provide financial support well into adulthood, helping fund everything for them.Stuart Hoffman, chief economist for the PNC Financial Services Group in theUS, said the number of young adults striking out on their own fell during the Great Recession. Although job growth for millennials since 2014 has improved, that doesn't necessarily mean that millennials are starting to fly the nest. He said, “They may like living at home and being able to save money.“ There's no doubt it has held back household formation and purchases of things people spend money on related to household formation and perhaps related to child-raising," Hoffman explained. "But they are probably traveling more and eating out more if they don't have a house expense or marriage. I don't know if it represents a change in moral values. But it's much more common for adult children to live in their parents’ homes because it's becoming part of the culture.1. What can we learn from the UBS Financial Services' report?A. Millennials are on good terms with their parents.B. Millennials are financially independent after college.C. Parents are unwilling to give their young adults allowance.D. Parents want their kids to stay with them forever.2. What does Hoffman think of young adults' living at home?A. It increases the consumption of household products.B. It may continue despite job growth.C. It is a sign of shift in moral values.D. It is new in American culture.3. What is the author's purpose of writing this passage?A. To introduce millennials' living habits.B. To stress the importance of financial independence.C. To explain why American young adults still live at home.D. To inform people of a social trend in theUS.BDepression（抑郁症）in young adult males, ages 18 or 19, is linked to a 20% greater risk of having a heart attack in middle age, according to a new Swedish study.The link can be partly explained by poorer stress resilience（抗压能力）and lower physical fitness among teens with mental disorders.Theresearch included 238,013 men born between 1958 and 1962 who were given examinations in adolescence（青春期）and were then followed into middle age（up to the age of 58 years）. A total of 34,503 men were diagnosed（诊断）with a mental disorder.The study found thata mental disorder in young adulthond was linked to a higher risk of having heart attack by middle age. Compared to men without a mental illness in young adulthood，the risk of heart attack was 20%higher among men with a diagnosis.“We already knew that menwho were physically fit in adolescence seem less likely to keep fitness in later years if they have low stress resilience” said study author Dr. Bergh, “Our research has also shown that low stress resilience is also connected with a greater tendency towards bad behavior, such as higher risks of smoking, drinking and other drug use.”“Better fitness in adolescence is likely to help protect against later heart disease, particularly if people stay fit as they age. Physical activities may also reduce some of the bad effects of stress. Those in poor health could benefit from additional support to encourage exercise and develop plans to deal with stress,” said Bergh.4. How does the author develop paragraph 3?A. By giving examples.B. By listing figures.C. By making a comparison.D. By drawing a conclusion.5. What are men with low stress resilience likely to do?A. Smoke more.B. Eat more.C. Sleep less.D. Do less exercise.6. What will Bergh agree with according to the last paragraph?A. Physical activitiesadd to stress.B. Stress may cause heart disease.C. Taking exercise is unnecessary.D. Staying fit is of great importance.7. In which section of a newspaper may this text appear?A. Entertainment.B. Health.C. Education.D. Fashion.CCanadaIs Our NeighbourCanada and the United States are neighbours.They are on the same land.They share the same long boundary(国界).These two nations are similar in many ways.Canada buys many goods from the United States.Cars and clothes are two examples.The United States also buys goods from Canada.Much of the paper used in the United States comes from Canada.Some of the oilweuse comes from Canada,too.Americans travel toCanadaon holiday.And Canadians often visit the United States.It is easy for the people of one country to go to the other country.Canadians read about the United States in newspapers and magazines.Many Americans watch Canadian baseball and hockey (曲棍球)matches on Sundays.However,there are important differences between theUnited Statesand Canada.The United States has more people.Because the population is smaller,there are more open places in Canada.There is much unused land.This is another important difference.8.Canadabuys from theUnited States.A.oil and paperB.nothingC.many thingsD.everything9.In the first paragraph “we” means ________.A.CanadiansB.AmericansC.ChineseD.students10.The people in theUnited Stateslike Canadian ________.A.baseballB.basketballC.newspapersD.oil11.Which of the following statements is WRONG?A.Canada has less people than theUSA.B.Canada has not used all the land.C.Canada is connected withAmerica.D.Canadians don’t like hockey.DA Chinese space mining company has designed a robot that can capture waste material left behind by spacecraft in outer space with a big net.The state-run Xinhua news agency recently reported that the robot launched on the government's Long March 6 rocket along with several satellites. The robot will also investigate deep space to observe small objects in the universe. The 30-kilogram robot, called NEO-01 , was developed by Origin Space. Pounded in 2019 and based in the southern Chinese tech hub(技术中心)Shenzhen, Origin Space has been devoted to exploring and using space resources, according to the company. The company says the robot will lead the way for future technologies capable of mining on asteroids(小行星).The world's first asteroid mining company, Planetary Resources, was established in 2009. Since then, more than 12 businesses around the world have entered the industry, including 3D Systems of the United States and Japan's Astroscale. Astroscale's technology uses magnets (磁铁)to gather up space waste. But a report on the Origin Space website says NEO-01 will use a net to capture waste and then bum it. Thousands of satellites have been launched worldwide. As they are used too long, many end up as waste and put other operating satellites at risk.Su Meng is the founder of Origin Space. He said the company plans to launch many space telescopes and more spacecraft to begin the first for-profit mining of asteroids by 2045. Su added that NEO-01 will serve as a prototype (雏形)of future space mining robots, which can use rich mineral resources on asteroids to support the development of the space industry.The Xinhua news agency reported that China was increasing efforts to land a spacecraft on a near-Earth asteroid to collectmaterials. China is also speeding up a plan to build a defense system against near-Earth asteroids. The country aims to follow Russia and the United States in becoming a major space power by 2030.12. Which of the following can correctly describe NEO-01?A. It weighs 60 kilograms.B. It was created by Planetary Resources.C. It will be burnt after finishing its mission.D. It is mainly used to catch space waste.13. What can be inferred from the text?A. China will be the most powerful in space by 2030.B. Origin Space will open more mines on asteroids.C. It is those useless satellites that make space waste.D. The robot will look into deep space for more waste.14. What does Su Meng think of NEO-01 ?A. It is promising and rewarding.B. It has benefited the space industry.C. It's a long way to produce it.D. It'll help make money for the company.15. What can be the best title for the text?A. NEO-01 , A Smart Robot Used in SpaceB. A Chinese Robot Can Catch Space WasteC. A New Robot Makes China a SpacePowerD. NEO-01 , the Pioneer of Future Space Robots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。

B Have you got the information taught by your teacher in class? Have you understood what you saw on the screen? Maybe everyone has their own learning style. Generally speaking, we gather information with our minds and bodies in different ways, such as seeing, hearing and doing. Then our brains deals with that information, organizing it and connecting it to things we are already aware of. In other words, our brains will deal with the information in different ways. Sometimes we think in pictures or words. Sometimes we remember details or the big pictures. For different people, their learning styles are different too. One person may find it hard to make out the information in written forms but easy to know it immediately in an oral description. However, another person might find difficulties with the picture but the written message. Now scientists say there exist seven basic learning styles. ·Linguistic: These people learn through listening, reading, speaking and writing. ·Logical: These people learn with formula (公式) and principles (原理). ·Visual: These people learn by seeing what they are studying. ·Musical: These people learn well when information is presented through music. ·Kinesthetic: These people learn from movement and physical activities.
