Without chemistry our lives would be unrecognisable, for chemistry is at work all around us. Think what life would be like without chemistry - there would be no plastics, no electricity and no protective paints for our homes. There would be no synthetic fibres to clothe us and no fertilisers to help us produce enough food. We wouldn’t be able to travel because there would be no metal, rubber or fuel for cars, ships and aeroplane. Our lives would be changed considerably without telephones, radio, television or computers, all of which depend on chemistry for the manufacture of their parts. Life expectancy would be much lower, too, as there would be no drugs to fight disease.没有化学反应我们的生活将会大变样,化学就在我们周围;没有化学生活会是什么样子——没有塑料,,家里没有电,也没有防护漆;不会给我们合成纤维,没有化肥帮助我们生产足够的食物;我们不能旅行,因为不会有金属、橡胶或燃料汽车、船只和飞机;我们的生活将会大大改变了没有电话、收音机、电视或电脑,所有这些依赖化学生产的部分;没有药物来抵抗疾病,预期寿命将低得多;2． The first and second laws of thermodynamics and the meaning of entropy will be discussed. and expanded upon in this lesson. It will be shown that energy transformations on a macroscopic scale — that is, between large aggregates of atoms and/or molecules —can be understood in terms of a set of logical principles. Thus thermodynamics provides a model of the behavior of matter in bulk. The power of such a model is that it does not depend on atomic or molecular structure. Furthermore, conclusions about a given process .based on this model, do not require details of how the process is carried out.探讨热力学第一和第二定律和熵的意义.和扩展在这个知识;也就是说它将表明能源在宏观上的转换,根据一组逻辑原则可以理解能量在大量的原子或分子内的转换;因此热力学定理提供了一个物质体积变化的模型;这样一个模型的能力在于它不依赖于原子或分子结构;此外,给定进程的结论依托于这种模式,不需要的详细说明过程是如何进行的3．Preparation of Cuen2cdaH2O: H2cda 4-羟基-2,6 吡啶二酸 g, mmol was dissolvedin water 10 mL and the pH value of the solution was adjusted to 7~8 with aqueous NaOH solution molL-1, then adding it dropwise to a methanol solution 10mL ofCuClO42·6H2O , and ethylenediamine mmol under stirring at room temperature.After the resulting small quantity of precipitates was filtered off, dark blue crystals suitable for X-ray structure analysis were obtained by slow evaporation of the filtrate at room temperature.制备CUen2cdaH2O:使克,的4 -羟基2、6吡啶二酸溶解在10ml水中加入氢氧化钠水溶液调整到pH值7 ~ 8,然后将它一滴一滴地添加到CuClO42·6H2O,的乙醇溶液和乙二胺,在室温下搅拌;在室温下,缓慢蒸发滤液,得到深蓝色晶体,用x射线分析它的结构4. Measure 50 ml of vinegar with a pipette and pour into a 250-ml beaker. Add 2 drops of phenolphthalein indicator. Fill a burette with a 1 N solution of sodium hydroxide NaOH and draw out the excess as described above. From the burette add NaOH to the beaker of vinegar until 1 drop of NaOH produces a pale pink color in the solution. Maintain constant stirring. The appearance of pink tells you that the acid has been neutralized by the base and there is now 1 drop of excess base which has turned the indicator. Read the burette and record this reading as the volume of base used to neutralize the acid. One molecule of NaOH neutralizes one molecule of acetic acid, or one gram-molecular weight of NaOH neutralizes one gram-molecular weight of acetic acid. Calculate the amount of acetic acid present in the vinegar. Report this amount as the percentage of acetic acid. 用移液管吸取50ml醋加入到250毫升烧杯,加2滴酚酞指示剂;在滴定管中加入1M的氢氧化钠溶液,去除刻度线以上的溶液,将氢氧化钠溶液加入到醋中,并不断震荡,至到加入一滴氢氧化钠溶液变成粉红色;出现粉红色的颜色,表示酸中和了碱,而且多余的一滴碱使指示剂变色;阅读并纪律中和酸消耗碱的体积;一个分子的氢氧化钠中和一个分子的醋酸,或一个分子重量的氢氧化钠中和一个分子重量的醋酸反应;计算醋酸在醋的量;报告醋酸的百分比;。

2019-2020学年华南理工大学附属中学高三英语期末试卷及答案

2019-2020学年华南理工大学附属中学高三英语期末试卷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AYou might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows canbe reduced by adding a little seaweed to their food.Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.Now, scientists from the University of California, Davis have answered several of these questions.The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's notadequateseaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world is going to avoid the worst effects of the climate crisis.Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.1. Why did the scientists do the experiment on the farm?A. To control the amount of seaweed.B. To record the weight cows gained.C. To confirm the effect of seaweed in real life.D. To measure the amount of seaweed cows ale.2. The underlined word “adequate” means ________ .A. commonB. specialC. lackingD. enough3. The passage is written to ________ .A. appeal to people not to raise the cowsB. encourage people to plant the seaweedC. remind people of controlling cows' weightD. call on people to take actions to reduce the pollutionBThe year 2020 will mark the beginning of the decade of the yold, or the “young old”, as the Japanese call people aged between 65 and 75. The traditional retirement age is 65. One might therefore expect peak retirement. By continuing to work, and staying socially engaged, the yold will change the world, as they have done several times before at different stages of their lives.The yold are more numerous, healthier and wealthier than previous generations of seniors. The yold are busier, too. In short, the yold are not just any group of old people. They are challenging the traditional expectations of the retired as people who wear slippers and look after the grandchildren. That will influence consumer, service and financial markets.The over-60s are one of the fastest-growing groups of customers of the airline business. The yold are vital to the tourism industry because they spend much more, when taking a foreign holiday, than younger adults.But for all this to happen,three big things will have to change, under pressure from the yold themselves. The most important is public attitudes towards older people, and in particular the expectation that the old ought to be putting their feet up and quietly retiring into the background. Then, government policies will have to change, too. The retirement age in many rich countries is still below the age to which many people want to work. The effective retirement age (the age at which people actually leave the workforce) is usually even lower. Third, higher numbers of healthy yold people will require drastic changes in health spending. Most diseases of ageing are bestmetwith prevention and lifestyle changes. But only about 2%~3% of most countries’ health-care spending goes on prevention. That will have to rise, because although the yold will constitute a bulge of comparative health andactivity over the next decade, by 2030 they will hit 75 and enter a long period of decline for which few rich countries are ready.4. What kind of people are the yold exactly?A. They are workaholics.B. They are full of energy.C. They enjoy being focused on.D. They like staying socially engaged.5. Why do the yold contribute to tourist industry?A. They like traveling more.B. They have more money.C. They consume more on travel.D. They have much free time.6. What’s the author’s attitude toward health-care spending on prevention?A. Unsatisfied.B. Subjective.C. Neutral.D. Active.7. What does the underlined word “met” in the fourth paragraph mean?A. dealt withB. come acrossC. satisfiedD. experienced.CAn unmanned Chinese spacecraft left the earth on a trip to the planet Mars on Thursday. The launch（发射）marks the start of one of China's most important space explorations. China's national space agency launched the spacecraft called Tianwen-1 fromthe Wenchang Spacecraft Launch Center on Hainan Island.The name Tianwen means “Questions to Heaven” in Chinese. The spacecraft took off on China's largest carrier rocket, the Long March 5, and about 36 minutes later, the spacecraft, including an orbiter（轨道飞行器）and a rover（漫游车），was sent into the Earth-Mars orbit. It is expected to reach the orbit of the red planet next February. Tianwen-1 will finish three scientific goals—orbiting the red planet, landing on the Mars and sending a rover to the landing site.Tianwen-1 carries several scientific instruments to observe the planet's atmosphere and surface. It will do a series of scientific researches on the planet's soil, geological structure, environment, atmosphere and water. Besides its daily work of exploring the surface of Mars for 90 days, it will also report back to the earth about its experiences on the red planet, which is millions of miles away. According to experts, discovering signs of life will be its first and most important scientific goal.Tianwen-1's successful landing will make China the second nation to place a spacecraft on Mars. The United States has landed eight vehicles on Mars since 1976. China will be the first to successfully orbit, land and place a vehicle in the same mission. This is China's first independent mission to Mars. The task in 2011 failed when a Russian rocket carrying a Chinese orbiter had problems after launch, and was unable to escape the Earth orbit.Last year, China's Chang e-4 spacecraft became the first to make a landing on the far side of the moon.8. When will Tianwen-1 enter the orbit of Mars?A. 36 minutes later.B. Next Thursday.C. In 90 days.D. Next February.9. What is the main task of Tianwen-1 according to experts?A. Orbiting the Mars.B. Landing on the Mars.C. Discovering signs of life.D. Sending a rover to the landing site.10. Which of the following statements is mentioned in the text?A. Tianwen-1 is the second vehicle landed on the Mars.B. The United States is the first to land vehicles on the Mars.C. Russia helped China place Tianwen-1 on the Mars.D. Chang，e-4 was the first to make a landing on the moon.11. Where can you find this article?A. In a newspaper.B. In a diary.C. In a sci-fi novel.D. In a guide book.DHi, Momis a hit inChina. Since its release in early February the movie has earned more than 5 billion yuan at the box office. It is currently the second-highest-grossing film ever released in the country, and may yet overtakeWolf Worrior2, an action film from 2017.Written and directed by Jia Ling, the film is adapted from her comedy routine from 2016 which explored her relationship with her mother, who died in an accident when Ms. Jia was 19. At a time when many people have been separated from their families, the themes of grief and filial piety (孝道) inHi, Mombring agreement.The film’s impressive box office income is also a reminder of the health of the industry inChinacompared withHollywood. In the West cinemas remain closed due to lockdown or operate at limited capacity; inChina, where many restrictions have been lifted, between 50% and 75% of seats are available to book. During the Spring Festival, Chinese cinemas made an estimated $1.5 billion in ticket sales – 71% of takings at the American box office in all of 2020.With cinemas shut, film-sales agent stopped bringingHollywoodmovies to market. That has given locally made films a chance to excel. Since 2013, domestic films have taken around 60% of total box office earnings. In 2021, that number may get closer to 100%.12. What can be inferred from the first paragraph aboutHi, Mom?A. It will be a success.B.Wolf Worrior2 will be released after it.C. It is better than Wolf Worrior 2.D. It may be the first-highest-grossing film inChina.13. Which statement is NOT true according to the text?A. The film industry inChinais developing better than that inHollywood.B. The film is based on a real story.C. You can’t go to cinema because there are many restrictions.D. Many people can’t see their families often nowadays.14. What is the author’s attitude towards local films?A. NegativeB. PositiveC. IndifferentD. Skeptical15. What can be a suitable title for the text?A. Local Movies Arise.B. China Film Industry.C.

Recent research shows that the best way so far is being clever at how you ask questions and listen to the answers.Much of this research is based on the idea that telling a lie is simply harder mental work than telling the truth. Making up a story takes more effort than simply recording something that happened. And like a writer, a liar has to keep all the unreal details in his memory and sound believable when he explains them.One method that seems to work is asking them to tell their story in reverse order. This is harder when the story isn't true and makes it easier for you to tell they are lying. An even more basic way that helps is to just ask more questions, especially unexpected ones. Truth-tellers can easily find more to say, but it's a challenge for a liar to come up with something that's not in his prepared story.Researchers suggest that you shouldn't lay all your cards on the table at the start, but only gradually present what proof you have. The liars' stories may not agree with that proof, making it clear that they're lying.So it looks like there are ways to increase the chances of catching a liar; we've just been basing our methods on the wrong stories. Low-tech ways of causing people to make mistakes in conversation seem to work better than any science about eye movement or machines used to recognize a liar. To find a liar, watch less and listen more.4. Why does the author mention the writer?A. To show it's hard to make up lies.B. To show it's hard to recognise a liar.C. To show writers know liars best.D. To show writers are very clever.5. What do we know about liars?A. They often have much to say.B. They often ask many questions.C. They usually prepare a made-up story.D. They usually feel good about themselves.6. What advice is given to help people catch liars?A. Asking them to set their stories down.B. Presenting your proof one by one.C. Telling different stories to them.D. Letting them ask questions.7. Which can be the best title for the text?A. Why People LieB. How to Stop People LyingC. Low-tech Ways to Find a LiarD. LiarsAre Smarter than ThoughtCIs renting clothes greener than buying them? Sustainable (可持续的) fashion expert Elizabeth Cline isn’t sure. Clothing renting is a hot new industry and businessmen are trying to attract shoppers who care about the environment. Last summer alone,Urban Outfitters, Macy’s, Bloomingdale’s American EagleandBanana Republicall announced renting services – a sure sign of changing times.But is renting fashion actually more environmentally-friendly than buying it? And if so, how much more? Journalist and author Elizabeth Cline researched this question in a feature article for Elle, and she concluded that it’s not as sustainable as it seems.Take shipping for example, which has to go two ways if an item is rented – receiving and returning. Cline writes that consumer transportation has the second largest carbon footprint of our collective fashion habit after manufacturing.Then there’s the burden of washing, which has to happen for every item when it’s returned, regardless of whether or not it was worn. For most renting services, this usually means dry-cleaning, which is a polluting process. All the renting services that Cline looked into have replaced perchloroethylene, a carcinogenic (致癌的) air pollutants that’s still used by 70 percent of US dry cleaners, with hydrocarbon (碳氢化合物) alternatives, although these aren’t great either. They can produce harmful waste and air pollution if not handled correctly.Lastly, Cline fears that renting services will increase our appetite for fast fashion, simply because it’s so easily accessible. There’s something called “share-washing” that makes people have more wasteful behaviors because a product or service is shared and thus is considered more eco-friendly. Uber is one example of this: advertised as a way to share rides and reduce car ownership, and yet it has been proven to discourage walking, bicycling and public transportation use.Renting clothes is still preferable to buying them cheap and throwing them into the bin after wearing them a few times, but we shouldn’t let the availability of these services make us self-satisfied. There’s an even better step – and that’s wearing what we already have.8. What do we know about Elizabeth Cline from the passage?A. She is trying to attract shoppers.B. She is an expert and journalist.C. She has created “share-washing”.D. She never rents clothes.9. Why does renting services increase people’s appetite for fast fashion?A. Because it is handled correctly.B. Because it is transported easily.C. Because it is fairly eco-friendly.D. Because it is easily accessible.10. What can we infer from the passage?A. Clothing renting became popular ten years ago.B. Consumer transportation has the largest carbon footprint.C. Renting clothes deserves further consideration.D. Uber is a good example of sharing rides.11. Which section of a newspaper does the text probably come from?A. Environment.B. Technology.C. Travel.D. Medicine.DBill Gates on how to fight future pandemicsWHEN HISTORIANS write the book on the covid-19 pandemic, what we've lived through so far will probably take up only the first third or so.The bulk of the story will be what happens next.I believe that humanity will beat this pandemic, but only when most of the population is vaccinated(接种疫苗）.Until then, life will not return to normal.As the pandemic slows in developed nations,itwill accelerate in developing ones.Their experience,however,will be worse.In poorer countries,where fewer jobs can be done remotely,distancing measures won't work as well.The virus will spread quickly,and health systems won't be able to care for the infected.Wealthy nations can help.But people in rich and poor places alike will be safe only once we have an effective medical solution for this virus,which means a vaccine.My hope is that,by the second half of 2021,facilities around the world will be manufacturing a vaccine.If that's the case,it will be a history-making achievement: the fastest humankind has ever gone from recognizing a new disease to immunizing（免疫）against it.Apart from this progress in vaccines,two other big medical breakthroughs will emerge from the pandemic.One will be in the field of diagnostics.The next time a novel virus crops up,people will probably be ableto test for it at home.Researchers could have such a test ready within a few months of identifying a new disease.The third breakthrough will be in antiviral drugs.We haven't been as effective at developing drugs to fight viruses as we have those to fight bacteria.But that will Researchers will develop large diverse libraries of antivirals,which they'll be able to scan trough and quickly find effective treatments for novel viruses.All three technologies will prepare us for the next pandemic by allowing us to intervene(干预）early when the number of cases is still very low.Our progress won't be in science alone.It will also be in our ability to make sure everyone benefits from that science.In the years after 2021,I think we'll learn from the years after 1945. With the end of the Second World War, leaders built international institutions like the UN to prevent more conflicts.After covid-19, leaders will prepare institutions to prevent the next pandemic.These will be a mix of national,regional and global organizations.I expect they will participate in regular"germ games”in the same way as armed forces take part in War games.These will keep us ready for the next time a novel virus jumps from bats or birds to humans.I hope wealthy nations include poorer ones in these preparations,especially by devoting more foreign aid to building up their primary health-care systems.This pandemic has shown us that viruses don't obey border laws and that we are all connected biologically by a network of microscopic germs,whether we like it or not.The best analogy(类比）for today might be November 10th 1942.Britainhad just won its first land victory of the war,and Winston Churchill declared in a speech: “This is not the end.It is not even the beginning of the end.But it is,perhaps,the end of the beginning.”12. What are the three technologies that will prepare us for the next pandemic?①manufacturing a vaccine fast②diagnosing a virus at home③developing antiviral drugs④allowing us to intervene earlyA. ①②③B. ①②④C. ①③④D. ②③④13. As far as poorer countries areconcerned,which of the following is TRUE according to this passage?A. pandemic disease is more likely to begin in poorer countriesB. Working from home can work well in poorer countries.C. Health systems are sufficient to care for the infected in poorer countries.D. Virus will cross borders if poorer countries fail to contain it.14. Why is the Second World War mentioned in Para.8?A. The fight against the COVID-19 is similar to the Second World War.B. People are suffering just as they were in the Second World War.C. We should cooperate globally just as we did after the Second World War.D. Countries are fighting each other like in the Second World War.15. What is the tone of this passage?A. pessimisticB. optimisticC. neutralD. indifferent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。

Your superpowers are activated by a special suit. The suit communicates with your brain. It allows you to do amazing things with only a thought. By concentrating on strength, for example, you can kick a soccer ball across a field. By focusing on swift actions, you can jump to the top of a tree.Such a connection between mind and machine may sound like a fantasy. To scientists, though, it is a very real goal. They are creating machines that let disabled monkeys walk. These machines may soon help disabled humans do the same. Unlike other bionic devices, these robotic “super suits” do not communicate with muscles and nerves. Instead, they have a direct line to the brain.In 2005, doctors drilled a hole in the skull of Hutchinson, who had lost her right arm in an accident. Then they inserted a sensor onto her motor cortex (大脑皮层运动区). Wires connected the sensor to a receiver on her head. After she recovered, researchers pluggedHutchinson’s receiver into a cable that relayed signals from her brain to computers. Then they connected a robotic arm to the computers. The computerscould interpretHutchinson’s brain signals to move the arm.Soon,Hutchinson, the computer, and the robotic arm became a team.Hutchinsonwas even able to lift her hand and drink from a cup. “She smiled when she put down that drink—that’s everything.” says Donoghue, a brain scientist.Today other scientists are building on that success. One of those scientists is Dr. Miguel Nicolelis, who designed a whole-body bionic equipment. In 2014, a disabled former athlete kicked the first ball of the World Cup Games wearing one of Miguel’s full-body exoskeletons.The exoskeleton was connected to brain signal sensors in the man’s cap. By thinking about kicking, he sent signals to a computer on his back. The computer then translated the signal into an exoskeleton-aided kick. Such designs may become common as scientists keep merging mind and machine.4.Which can best describe the tone of paragraph 1?A. Narrative and serious.B. Persuasive and critical.C. Informative and objective.D. Descriptive and imaginative.5. What is paragraph 3 mainly about?A. Reason of the experiment.B. Results of the experiment.C. Process of the experiment.D. Significance of the experiment.6. Why is Dr. Miguel’s exoskeleton special?A. It can be used on animals.B. It can move the whole body.C. It was supported by computers.D. It was connected directly to the brain.7. What can be inferred from the last paragraph?A. Robotic suits may be widely used to help disabled people.B. Exoskeleton is more common thanHutchinson’s bionic arm.C.Scientific experiments are commonly carried out in football fields.D. Disabled athletes can now play football again with the help of computer.CThe climate change is already eating into the output of the world's agricultural systems, with productivity much lower than it would have been if humans hadn't rapidly heated the planet, new research has found.Advances in technology, fertilizer (化肥)use and global trade have allowed food production to keep pace with an increasing global population since the 1960s. But rising temperatures in this time have acted as a handbrake (手刹) to farming productivity of crops, according to the new research, published in Nature Climate Change. Productivity has actuallyslumpedby 21% since 1961, compared to if the world hadn't been affected by global heating.With the global population set to rise to more than 9 billion by 205, the UN'S Food and Agriculture Organization has estimated that food production will have to increase by about 70%,with annual crop production increasing by almost 1 billion tons and meat production by more than200mtons a year by this point. Meanwhile, global temperatures are rising at a rate that scientists warn is extremely dangerous for human civilization.“The impact already is larger than I thought it would be,” said Ariel Ortiz-Bobea, an economist atCornellUniversitywho led the research. “It was a big surprise to me. The worry I have is that research and development in agriculture takes decades to translate into higher productivity. The projected temperature increase is so fast that I don't know if we are going to keep pace with that.”Weston Anderson, a researcher of food security (安全) and climate at Columbia University who didn't take part in the study, said the new research provides fresh insight into the importance of the impact upon agriculture.“The regions that this paper highlights as experiencing the largest reductions in agricultural productivity-CentralAmericaand theSahel- contain some of the least food secure countries in the world, which is a real concern,” he said.8. What does the underlined word “slumped” in paragraph 2 mean?A. Fallen.B. Gathered.C. Approached.D. Benefited.9. What is Ariel Ortiz-Bobea worried about?A. Fertilizer is used in food production.B. Population will rise to over 9 billion.C. Global temperatures are rising too fast.D. Agricultural research needs many years.10. What can we learn about Weston Anderson?A. He puts forward a different solution.B. He proposes carrying on with the research.C. He pays more attention to food insecure regions.D. He supports improving agricultural productivity.11. What is the best title for the text?A. The Impact of Growth in Farm ProductivityB. Productivity in Agriculture is GrowingC. Causes and Effects of Global HeatingD. Rapid Global Heating is Hurting Farm ProductivityDNowadays organic food hasbecome a fashion. Organic food sales reached a record of $ 45.2 billion in 2017, making it one of the fastest-growing parts of American agriculture. Some people may buy organic food for these reasons like resource cycling and biodiversity, but most people may choose organic food because they think it's healthier. While a small number of studies have shown relationships between eating organic food and reducing risks of being ill, no studies, up to now, have answered the question whether eating organic food can improve health.According to the United States Department of Agriculture(USDA), organic food does not suggest anything about health. In 20155 Miles McEvoy, then chief of the National Organic Program for the USDA, refused to admit any health benefits of organic food, saying the question has nothing to do with the National Organic Program. Instead, the USDA thinks that organic refers to a production method that increases cycling of resources keeps ecological balance, and protects biodiversity.I'm an environmental health scientist who has spent over 20 years studying pesticides that do harm to human beings. Several years ago, I was part of the study on whether an organic diet can reduce pesticide exposure. This study focused on a group of pesticides which have always been harmful to children's brain development. We found that children who ate traditional diets had nine times higher exposure to these pesticides than children who ate organic diets.Last month, I published a small study that suggested a path forward to answering the question whether eating organic food actually improves health. My study got a lot of attention. While the results were novel, they didn't answer the big question. As I toldThe New York Timesin 2003, “What does this really mean for the safety of my kids? But we don't know. Nobody does. It was true then, and it's still true now.”12. Why do most people prefer to buy organic food?A. For its health benefits.B. For biodiversity.C. For its delicious taste.D. For resource cycling.13. What does the USDA suggest about organic food?A. It can improve people's health.B. It is produced in an environment-friendly way.C. It can reduce risks of being ill.D. It has nothing to do with the National Organic Program.14. What can be concluded from the author's study?A. Pesticides don't harm children's brain.B. Traditional diets benefit people's health.C. Organic diets can reduce pesticide exposure.D. The results are meaningful to children's safety.15. What is the best title for the text?A.What Is Organic Food?B. Is Organic Food Healthier?C. How Should We Avoid Pesticides?D. What Are the Benefits of Organic Food?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。

2020届华南理工大学附属中学高三英语上学期期末试卷及参考答案

2020届华南理工大学附属中学高三英语上学期期末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AWhile Jennifer was at home taking an online exam for her business law class, a monitor（监控器）a few hundred miles away was watching her every move.Using a web camera equipped in Jennifer'sLos Angelesapartment, the monitor inPhoenixtracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked remotely to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past？Or was she slowing down？In the battle against cheating, this is thecutting edgeand a key to encourage honesty in the booming field of online education. This technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't searched the Internet to get the right answers.Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses". Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students’ identities using personal information, such as the telephone numbers they once used.Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.1. Why was Jennifer watched in an online exam?A. To correct her typing mistakes.B. To find her secrets in the room.C. To keep her from dishonest deeds.D. To prevent her from slowing down.2. What does the underlined expression "cutting edge" in Paragraph 3 probably mean?A. sharpening toolB. advanced techniqueC. effective ruleD. dividing line3. How can some programs find out possiblecheaters?A. By scanning the Internet test questions.B. By checking the question answering speed.C. By producing a large number of questions.D. By giving difficult test questions.BI was in the second year of my Ph. D. program when a colleague asked what I would do if I had an extra hour every day. Without much consideration, I said I would use it to help others. The question kept coming to my mind. Like many graduate students, I was overwhelmed (难以承受的) with research, teaching, coursework, and some attempt at a personal life. Still, I asked myself, "Do I really need a 25th hour to help other people-or do I need to make better use of the 24 hours I have?"I needed something to help me return to my old self. After that conversation with my colleague, I googled (谷歌搜索) “volunteer opportunities near me”. A local organization that drives people to stores or appointments was looking for volunteers. Having grown up in a rural village where everyone knew oneanother and my grandparents were always close by, I thought serving senior citizens in my new hometown might be just what I needed.A short time later, I started to volunteer for an organization that provides transportation for senior citizens and people with disabilities. To my surprise, adding this activity to my busy life was just what I needed to calm the confusion I was feeling as a first-generation international graduate student.I started to volunteer about 3 hours every weekend, the time I otherwise would have wasted oversleeping or scrolling (滚屏) through social media. Sharing stories with my riders was much more rewarding. What they told me about their lives helped me realize that in every corner of the world, humans are connected with the languageof emotions. And seeing how eager my riders were to spend time out and about inspired me to think about how to spend my time, which used to slip away. My previously overwhelming schedule began to feel manageable.I'm proud of who I have become, and I continue to reflect on how I'm using the most valuable thing in life: my time.4. Why did the author ask himself the question in Paragraph 1?A. He wanted to return to normal life.B. He was busy but wanted to help others.C. He couldn't bear too much school work.D. He couldn't answer his colleague's question.5. How did the author find the volunteer job?A. A colleague recommended it.B. A local organization offered it.C. He got it from his grandparents.D. He got it by surfing on the Internet.6. What made the author feel his volunteer job was worth doing?A. Communicating with his riders.B. Improving his language learning.C.

He found a good way to live a free and quiet life.C. He realized he had wasted too much time pursuing his Ph.D.D. It inspired him to spare more time to accompany his grandparents.CWhen I was trying to find a place where to spend my December holidays, I met by chance some cheap flights to Iceland. After checking just a few winter pictures of Iceland, I realized that the country, known as the land of fire and ice, during the cold months of the year could offer me experiences I had never had before.For sure you can’t miss the chance to go to Iceland in winter if your traveling wish list includes at least one of the crazy experiences Iceland can offer. Iceland in the North Atlantic Ocean is a paradise (乐园) for all those who want to see the northern lights, experience cold weather conditions and put themselves in geothermal (地热的) baths while the snow is falling on their head.The best way to move around Iceland is with a rental car. Distances are huge and public transport in winter is not really common out of the major towns. As we wanted to be even more convenient we decided to rent a small camper (野营车). Sleeping and cooking in a camper saved us a lot of driving, money and gave us the chance tobe always in the right place at the right time.There were also no locals and in many cases no tourist facilities (设备). For us, as we slept in a camper, it was easier. But for tourists traveling by normal cars it is necessary to check the opening times ofhotels and restaurantsas many of them run just from June to September.It is amazing to experience how the weather is changing in Iceland. However, Icelanders prefer to stay inside their houses. They have even no time to complain about the weather in December. All they care about is Christmas. They love to decorate their houses, sing Christmas songs and eat typical Christmas food.8. Why is Iceland famous as the land of fire and ice?A. Because tourists would like to play with fire on the ice.B. Because it is too dry to easily cause fire to happen.C. Because it is hot inside a house and cold outside.D. Because there exist hot springs and freezing ice.9. What did the author think of the rented camper?A. It was not only practical but also economical.B. It was convenient but cost them more money.C. It provided the best chance to see the new country.D. It was much faster than other public transport.10. What does the last paragraph imply?A. The Icelanders prefer to live with their family.B. The joy of Christmas drives the freezing weather away.C. December is the coldest month of the year.D. The Icelanders are always positive and stay outside.11. What does this passage most probably come from?A. A textbookB. A scientific reportC. A travel magazineD. A news reportDImust have always known reading was very important because the first memories I have as a child deal with books. There was not one night that I don’t remember mom reading me a storybook by my bedside. I was extremely inspired by the wonderful way the words sounded.I always wanted to know what my mom was reading. Hearing mom say, “I can’t believe what’s printed in the newspaper this morning,” made me want to grab it out of her hands and read it myself. I wanted to be like my mom and know all of the things she knew. So I carried around a book, and each night, just to be like her, I would pretend to be reading.This is how everyone learned to read. We would start off with sentences, then paragraphs, and then stories. It seemed an unending journey, but even as a six-year-old girl I realized that knowing how to read could open many doors. When mom said, “The C-A-N-D-Y is hidden on the top shelf,” I knew where the candy was. My progress in reading raised my curiosity, and I wanted to know everything. I often found myself telling my mom to drive more slowly, so that I could read all of the road signs we passed.Most of my reading through primary, middle and high school was factual reading. I read for knowledge, and to make A’s on my tests. Sometimes, I would read a novel that was assigned, but I didn’t enjoy this type of reading.I liked facts, things that are concrete. I thought anything abstract left too much room for argument.Now that I’m growing and the world I once knew as being so simple is becoming more complex, I find myself needing a way to escape. By opening a novel, I can leave behind my burdens and enter into a wonderful and mysterious world where I am now a new character. In these worlds I can become anyone. I don’t have to write down what happened or what technique the author was using when he or she wrote this. I just read to relax.We’re taught to read because it’s necessary for much of human understanding. Reading is an important part of my life. Reading satisfies my desire to keep learning. And I’ve found that the possibilities that lie within books are limitless.12. Why did the author want to grab the newspaper out of mom’s hands？A. She wanted mom to read the news to her.B. She couldn’t wait to tear the newspaper apart.C. She couldn’t help but stopmom from reading.D. She was eager to know what had happened.13. According to Paragraph 3, the author’s reading of road signs shows___________.A. her own way to find herselfB. her eagerness to develop her reading abilityC. her growing desire to know the world around herD. her effort to remind mom to obey traffic rules14. The author takes novel reading as a way to___________.A. explore a mysterious landB. develop an interest in learningC. get away from a confusing worldD. learn about the adult world15. What could be the best title for the passage？A The Pleasure of Reading B. Growing Up with ReadingC. The Magic of ReadingD. Reading Makes a Full Man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。

To follow the rules of the airport.BUK physicist Isaac Newton once said, ''Nature is pleased with simplicity and nature is no dummy (傻子). '' Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we break the rules, she is likely to be cruel andlash out at us.The outbreak of the novel coronavirus pneumonia (新型冠状病毒肺炎, NCP) in China and some other countries at the beginning of this year is an example. According to Xinhua News Agency, the new coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host (中间宿主). It's believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei province, where live wild animals were sold.The Wall Street Journal reported that Dr Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, ''This outbreak is a lesson for us. On a global scale, human population density, wildlife diversity, and land use change are what drive new pandemics (流行病). ''In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans. Chinese ancients always pursued the harmony between nature and human beings.However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify (改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.Although we don't know for sure what first caused the NCP outbreak, Brian Lamacraft at Medium said it's time for people to ''reflect on our relationship with our planet'' and ''reconnect with this world and everything that we've been given''. After all, according to US poet Gary Snyder, ''Nature is not the place to visit. It's our home. ''4. What does the phrase ''lash out at'' in Paragraph 1 probably mean?A. punishB. controlC. testD. challenge5. What lesson did Daszak think human beings should learn from the NCP outbreak?A. Bats are one of the most dangerous wild animals.B. It's impossible to prevent new pandemics globally.C. We should stop the wildlife trade around the world.D. Humans should live peacefully with nature.6. What is the main idea of Paragraph 5?A. How human beings become their own masters.B. How human activities cause global warming.C. How human beings break the balance of nature.D. How humans use technology to improve their lives.7. What is the author's purpose in writing this article?A. To reflect on the NCP outbreak.B. To explain what led to the NCP outbreak.C. To describe experts' predictions on new pandemics.D. To compare ancient and modern attitudes toward nature.CJack was 11 months old in the spring of 2015 when his parents, Erika and Christopher, recognized his development was not progressing as it should. The feeling was familiar to the couple. Just a few months earlier, Jack’s brother Chase, who is 16 months older, had been diagnosed with autism(自闭症) after he did not reach motion and language standards as expected.Jack’s behaviors were similarly delayed, and his parents moved quickly to seek help. Today, Jack is 5 — he celebrated his birthday on May 13 — and he can speak in full sentences and read. After two years at a preschool that specializes in services for children with developmental disabilities, he will start kindergarten in theSmithtownschool district in September. “Our family’s experience is a good example of the power and effectiveness of early intervention. The services our boys have received made all the difference,” the parents said.According to scientists, autism can be detected at 18 months or younger, and by age 2 a diagnosis can be considered “very reliable.” The parents said they were happy with Chase’s success at the learning center, but stillhad concerns for Jack because he was not speaking. Developing social and communication skills can be among the greatest challenge for individuals with autism, even if they are able to say a few words early on. “We didn’t know if he was ever going to talk,” Erika said. “That was my biggest fear. We just didn’t know.”Looking ahead, the parents are cautiously optimistic about Jack’s next educational move. He doesn’t handle change well, they said, and he likes to know his routine. Still, they expressed confidence that his time at the learning center has given him the skills he needs to be successful.8. How did Jack’s parents know he suffered from autism?A. They found the baby clever.B. They judged by their experience.C. They found he didn’t develop.D. They checked on him in the hospital.9. What did the parents think of the early intervention?A. It made no difference to the babies.B. It benefitted the babies greatly.C. It got their babies more disabled.D. It helped their babies speak fluently.10. What can we learn from the third paragraph?A. Autism can be confirmed at 18 months old.B. Jack’s parents were confident about his motor skills.C. Chase’s parents were doubtful about his developmentD. Jack’s parents worried about his language skills most.11. What is the text mainly talking about?A. Autism can be curedif parents take actions early.B. Parents should be confident about their children’s future.C. Early intervention in autism could improve children’s life.D. Communication skills should be developed as early as possible.DChancellor of the Exchequer George Osborne said yesterday he would use the autumn spending review to increase Britain’s￡12bn-a-year aid budget towards humanitarian(人道主义的) causes in the wake of the European refugee(难民) crisis.Britainpromised to spend 0.7 percent of state general product on aid, meaning the budget could rise sharply by the end of the decade as the economy grows.Mr Osborne also said more of the aid budget could be given to help local government with housing costs for incomers, without breaking international guidelines.“We will use the foreign aid budget to help with the costs of these refugees. People ask about the pressure on public services; we’ll have extra money to help with that.”The government was unable to give a figure for how much aid money could be handed to local authorities: it would depend on how many refugees are accepted.David Cameron, Prime Minister, will set out his position on aid for refugees today. It is reported thatBritainwill accept at least 10,000 extra people from camps on theSyriaborder. He will use a statement in the House of Commons to flesh out plans — announced inMadridon Friday — to take more people.A report inThe Sunday Timesthat the UK would take 15,000 Syrians, not far from the 18,000 figure demanded by the EU, was described by “Downing Street” as a “guess”.TheUKwill offer to resettle Syrians directly from refugee camps inJordan,LebanonandTurkey— but not those who have already reached the EU.12. What is the main idea of the passage?A. Britain tried to help refugees.B. People doubtBritain’s kindness.C. Britain tried to explain its behavior.D. Refugees like to live inBritain.13. What can we infer from the first two paragraphs?A. Britain’s economy grows rapidly.B. Britain will use little of its money to help refugees.C.

House of Commons declare a general plan.D.Britaincan hold 15,000 refugees at most.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。

Once you’ve finished learning about the wildlife in the animal nursery, reptile (爬行动物) side rooms, horse barn and other areas of the attraction, make sure to mark your schedule for fun seasonal happenings, such as the Easter Egg Games and the scary, crazy Halloween Shows.Entry on Wednesdays is by suggested donation; children aged two and under free.Children’s Museum of the ArtsThe Children’s Museum of the Arts welcomes 135,000 little visitors each year through its doors.

Children’s Museum of the Arts.BThere are three of us in the laboratory: Jules, me and Dr. Leonards. Leonards asks me to sit in front of Jules. As I do, he looks me in the eye and starts to move his face through a series of emotions-happy, confused, surprised, glaring. I'm attracted by his display, feeling delight when hegrinsand feeling serious when his eyes narrow angrily. None of this would be a surprise, of course, if Jules were a human. But he's a robot head on a table.The most special thing is that, consciously(有意识地), there's no mistaking Jules for a real person. Although he has surprisingly realistic skin, his eyes don't fit firmly against his lids, and he has a terrible hairpiece. Yet, as I walk into the room, I experience a complex worry of feeling in his direction. It's not at all like entering an empty space. It's a bit awkward for Jules’ shining false hair. Some unconscious part of me is responding to him as if he's real. This matters, because if we're to one day live comfortably along with robots , an understanding of how we instinctively(本能地) react to them is significant. The study of these issues is the frontier of a new scientific research; human-robot interaction.Jules was built as part of an attempt to understand the emotions that can be communicated by a human. “All the robots we'vebuilt so far don't have that rich emotions. We wanted to build a robotic face, with small motors that mimic(模仿) all the muscles you have, so we could discover what it could express. "Such research is becomingincreasingly important, says Dr. Leonards, partly because our rapidly ageing population will soon need the help of robots with which they can effortlessly interact.4. What does the author think of Jules?A. He ignored him in his place.B. He didn't treat him as only a robot.C. He was afraid of his being there.D. He mistook him for a real person.5. What is the purpose to build such a robot?A. To help humans of old ages.B. To carry out a scientific research.C. To take the place of human labour.D. To make an interaction with human.6. What doesthe underlined word “grins” mean in Paragraph1?A. Smiles.B. Shakes.C. Worries.D. Cries.7. What may be the best title for the text?A. Human And RobotB. Success Of Making A RobotC. Robot Will Replace ManD. Difference Between Man And RobotCEach year, the women of Olney and Liberal compete in an unusual footrace. Dressed in aprons (围裙) and headscarves, they wait at both towns’starting lines. Each woman holds a frying pan with one pancake inside. At the signal, the women flip (轻抛) pancakes and they’re off!This “pancake racing” tradition is said to have started on Shrove Tuesday, 1445, in Olney. Shrove Tuesday is the day beforethe Christian season of Lent (大斋戒) begins. During Lent, many people decide to give up sugary or fatty foods.Legend says that in 1445, an Olney woman was making pancakes to use up some of her sugar and cooking fats before Lent. She lost track of time and suddenly heard the church bells ring, signaling the beginning of the Shrove Tuesday service. Realizing that she was going to be late for church, she raced out the door still wearing her apron and headscarf and holding her frying pan with a pancake in it. In the following years, the woman’s neighbors imitated her dash to church, and pancake racing was born.The rules are simple. Racers must wear the traditional headscarf and apron. They must flip their pancakes twice - once before starting and once after crossing the finish line. After the race, there are Shrove Tuesday church services. Then Liberal and Olney connect through a video call to compare race times and declare a winner.In both towns, the races have grown into larger festivals. Olney’s festival is an all-day event starting with a bigpancake breakfast. Liberal’s festival lasts four days and includes a parade, a talent show, and contests that feature eating and flipping pancakes. Although the women’s race is still the main event, both towns now hold additional races for boys and girls of all ages.8. How did pancake racing start?A. A woman in Olney created it.B. Women made pancakes before Lent.C. A woman dashed to church with a pancake.D. People followed the suit of an interesting incident.9. What should racers obey during the race?A. They can wear fashionable headscarves and aprons.B. They must flip their pancakes once in the race.C. They must flip their pancakes at the beginning of the race.D. They can flip their pancakes in the middle of the race.10. What can we learn about the race from the last paragraph?A. People can show their talent in Olney festival.B. People can enjoy a one-day holiday in Liberal.C. The race is not only intended for women now.D. People can have a big pancake breakfast in both towns.11. What is the text mainly about?A. The origin of pancake racing.B. The history of pancake racing.C. The development of pancake racing.D. The introduction to pancake racing.DUntil quarantine (隔离期) ends, we are left picturing what sport we might do: working out at the gym, playing on a competitive sports team, swimming, biking, or rock climbing. However, we don’t often think of martial arts as possible activities; instead, we rule it out because we think it’s dangerous, uncommon, and even, impossible. Martial arts aren’t considered a sport, right?Well, here’s some good news: you’re wrong! Martial arts aren’t much more common than people think, and you can start learning at any age. Practicing martial arts is a great way to keep in shape, both physically andmentally. They’re much less boring and much lessarduoussport than they’re usually described as in movies, so do not worry that they need a lot of effort.Martial arts generally require you to focus on the position and movement of every one of your legs and arms, sometimes even your breathing too. Think about it: when you leave the gym, your mental state has improved and you are much calmer. This is because you’ve only paid attention to one activity. It is a great way to clear your head. Andpracticing it can help you learn to stay more focused, which is the greatest advantage of martial arts training.Martial arts also improve your coordination (协调性), and greatly improve your posture (姿势). I have personally seen students go from slouching (没精打采) to walking tall with their shoulders back in just a couple of months.There are many styles and countless kinds of martial arts. Whichever one you like better, know that all of them are good choices.12. What can we know about martial arts from the first two paragraphs?A. They often have people hurt.B. They are difficult to practice.C. People have a wrong view on it.D. People practice them more often.13. What does the underlined word “arduous” in paragraph 2 mean?A. Interesting.B. Difficult.C. Friendly.D. Exciting.14. What is the biggest benefit of practicing martial arts?A. Adjusting the breath.B. Enjoying one’s free time.C. Correcting the movement.D. Keeping one’s attention.15. What does the writer think of martial arts?A. They are notsports.B. They attracted many teenagers.C. They are beneficial and helpful.D. They were invented to protect others.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.A traveler's journal.C.A news report.D.A trip guide.BPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CA 25-year-old American with a university degree can expect to livea decade longer than a peer who dropped out of high school. Although researchers have long known that the rich live longer than the poor, this education gap is less well documented. And although the average American’s expected span(预期寿命) has been smooth in recent year—and, shockingly, even fell between 2015 and 2017—that of the one-third with a bachelor’s degree has continued to lengthen.This gap in life expectancy is growing, according to new research published in the report of the National Academy of Sciences. Anne Case and Angus Deation ofPrincetonUniversityfound that the lifespans of those with and without a bachelor’s degree started to become different in the 1990s and 2000s. This gap grew even wider in the 2010s.What is the link between schooling and longevity(长寿)? Some argue that better-educated people develop healthier lifestyles: each additional year of study reduces the chances of being a smoker and of being overweight. The better-educated earn more, which in turn is associated with greaterhealth.Ms Case and Mr Deaton argue that changes in labor markets, including the rise of automation and increased demand for highly-educated workers, coupled with the rising costs of employer-provided health care, have decreased the supply of well-paid jobs for those without a degree. This may be contributing to higher rates ofalcohol and drug use, suicide and other “deaths of despair”.The authors argued that the educational gap in mortality(致死率) will widenin the wake ofthe covid-19 pandemic. ForAmerica’s overall life expectancy to start climbing again, improvements will be needed across all social groups, not just among the privileged few.8. When did the lifespans of people with and without a degree vary greatly?A. In the 1990s.B. In the 2020sC. In the 2000sD. In the 2010s9. According to the article, changes in labor markets reduce jobs for those without a degree. Which change is NOT included?A. The rising spending of employer-provided health care.B. The gap in life expectancy.C. Raised request for better-educated workers.D. The development of automation.10. What does the underlined phrase “in the wake of” probably mean ?A. afterB. untilC. beforeD. while11. What is the best title for the text?A. Changes in labor market.B. Quit bad habits by Further studyC. Educated Americans live longer.D. Highly-educated people develop healthier lifestyles.DWhen you say the word donkey, whatthings come to your mind? A few people might say they’re cute, but the majority think they’re stubborn, dumb and all-round less capable than their horse s.However, this wasn’t the case for a recently unearthed ancient Chinese noblewoman who was unexpectedly found buried with her donkeys. Published in the journal Antiquity in March, Chinese archaeologists (考古学家) first discovered the tomb in Xi’an, Shaanxi, in 2012. The team examined the remains and identified the body as Cui Shi, a Tang Dynasty high-born lady who died in 878 AD.Speaking to Science Magazine in 2012, the study’s co-author, Fiona Marshall, said the finding caused confusion as “donkeys … are not associated with high-status people”.However, following years of further research, the team discovered artworks and artifacts that showed a sportknown as “Lvju”. This was similar to modern-day polo (马球)and was popular among noble (高贵的) women at the time. They preferred to use donkeys instead of full-sized horses for safety reasons, due to their smaller size and slower speed.Speaking to CNN, Marshall later said, “Historical documents also showed that ladies of the late Tang court loved to play donkey polo.”At that time in Chinese history, animals were often placed in tombs so that they could be used for a specific purpose in the afterlife. The study determined that Cui Shi likely requested that her beloved donkeys be buried with her, so that she could continue her favorite sport after death. In total, three donkeys were found inside her tomb with riding gear (装备), including stirrups (马镫). “This context provides evidence that the donkeys in her tomb were for polo, not transport,” lead author Hu Songmei of the Shaanxi Academy of Archaeology told Science Magazine.Before the study, it was believed that donkeys were only used to carry loads, but now it may be time to see them as a sign of achieving high social status(地位), well, in ancient times.12. What do most people think of donkeys, according to the text?A. They are as adorable(可爱的) as horses.B. They are stubborn and not so capable.C. They were necessary in ancient sports.D. They were a sign of high social status.13. Why did Fiona Marshall feel confused when she discovered the donkeys?A. She didn’t connect donkeys with nobles.B. She hadn’t seen donkeys in ancient tombs before.C. She didn’t expect to find donkeys in a woman’s tomb.D. She didn’t understand why animals were in human tombs.14. What do we know about the sport “Lvju” from the text?A. Horses were preferred in Lvju.B Lvju was similar to modern-day soccer.C. Lvju was popular among common people.D. Donkeys were preferred in the sport for safety.15. The donkeys were found in the tomb of Cui Shi probably because _______.A. she intended to use them for transport after deathB. her family didn’t want her to be lonely after deathC. she wanted to continue to play Lvju after deathD. noble women needed donkeys to maintain their dignity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。

2020年华南理工大学附属中学高三英语上学期期末试题及答案解析

2020年华南理工大学附属中学高三英语上学期期末试题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ADuring ancient times, children didn’t have smartphones, iPad or computers to entertain themselves. Instead, they came up with interesting games to play.★Stone ballsDuring the Qing Dynasty, kicking a stone ball around was a popular sport in the northern part of China, and it was often played in the winter to protect kids from the cold. Stones were carved into small balls and kicked along with feet. In 1999, the sport was included in the 6th National Ethnic Group Traditional Sports Meeting held in Beijing.★Flying kitesKites have quite a long history. The earliest kites were made of wood, instead of paper. Nowadays, the four most famous kites are the Beijing kite, Tianjin kite , Weifang kite and Nantong kite, of which each has distinctive features. The kite which resembles a swallow is a well-known Beijing style.★Hide-and-seekHide-and-seek is a traditional game for children, popular around the nation. There are two ways to play: covering a child’s eyes while other kids run around to tease(戏弄) him or, more commonly, participants hide and one child must try to find them.★Playing diabolosA diabolo is always made of wood or bamboo and has empty space in the center. By juggling(边抛边接) the diabolo on the rope, the high-speed spinning diabolos will make a sound like a whistle. Playing diabolos is an interesting folk game, especially popular in North China. Playing diabolos was also included in the first group of national intangible cultural heritage(非物质文化遗产).1.Why did ancient children often play stone balls in the winter?A.To practice their feet.B.To warm themselves.C.To train their skills.D.To relax themselves.2.Which kites are swallow-shaped?A.Weifang kites.B.Tianjin kites.C.Beijing kites.D.Nantong kites.3.Why does playing diabolos make a sound?A.Because the diabolo’s center is empty.B.Because the high-speed spinning diabolo is light.C.Because the diabolo is equipped with a whistle.D.Because ropes’ surface moves against the diabolo’s.BIn the Pacific Northwest during winter, 5:15 am might as well be the dead of night. The alarm goes off and the onlylight is the red glow from my clock. My body says, “Go back to bed.” But I don’t. I know my running partner will be waiting in the street and I’m not going to stand her up. Then I walk onto the road, complaining about the cold and wishing I were back under my warm covers.If you’d have asked me a year ago if I could see myself running at 5:15 on a winter morning, I’d have laughed. Morning just wasn’t my thing and running in the morning was something I didn’t even consider. “I prefer to work out in the middle of the morning or in the afternoon,” I’d say to my friends who go to the gym before work.Then, last fall I reconnected with an old neighborhood friend. She’d been running in the morning and taken off forty pounds that year. When I looked in the mirror, I knew I could benefit from the same kind of weight loss. I asked if I could join her. I knew I needed to change something if I was going to get back in shape.The first two months were especially hard, because we ran twice a week at 5:15 am and I slept till 7:00 the other mornings. But as I’ve adjusted to the routine of running, I’ve discovered great joys that make it even more worthwhile than a little weight loss.While I haven’t lost forty pounds yet, it’s amazing how much more energy I have and how much stronger I feel. Because of the morning run, the rest of my day is more productive. I wouldn’t say I’ve become a morning person, but I would say morning running is now my thing.4. What can we know about the author from paragraph 1?A. 5:15 is the ideal time for her to exercise.B. She prefers to run without any company.C. She takes the run with warm clothes on.D. She goes for a run in spite of the cold and early rise.5. What was the author’s attitude to morning running a year ago?A. Scared.B. Unfavorable.C. Supportive.D. Confused.6. What made the author begin to run in the morning?A. Her partner’s encouragement.B. Her friend’s suggestion.C. Realizing the benefits of running.D. Realizing the harm of being fat.7. What effect does morning runninghave on the author?A. She has become slim again.B. She has become more confident.C. She has become more energetic.D. She has become more exhausted.CI don’t want to talk about being a woman scientistagain. There was a time in my life when people asked constantly for stories about what it’s like to work in a field dominated (controlled) by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space, time and the nature of black holes.At 19, when I began studying astrophysics (天体物理学), it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as a post-doctor doing space research, the issue started to bother me. My every achievement — jobs, research papers, awards — was viewed through the lens (镜片) of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.Then one day a few years ago, out of my mouth came a sentence that would eventually become my reply to any and all provocations (挑衅): I don’t talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn’t want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don’t study sociology or political theory.Today I research and teach at Barnard, a women’s college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer, 45.I know some of my students worry how they will manage their scientific research and a desire for children. And I don’t dismiss those concerns. Still, I don’t tell them “war” stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that’s a sight worth talking about.8. Why doesn’t the author want to talk about being a woman scientist again?A. She is fed up with the issue of gender discrimination (歧视).B. She feels unhappy working in male-dominated fields.C. She is not good at telling stories of the kind.D. She finds space research more important.9. From Paragraph 2, we can infer that people would attribute (把……归因于) the author’s failures to ________.A. the burden she bears in a male-dominated societyB. her involvement in gender politicsC. her over-confidence as a female astrophysicistD. the very fact that she is a woman10. What did the author constantly fight against while doing her Ph.D. and post-doctoral research?A. Lack of confidence in succeeding in space science.B. Unfair accusations from both inside and outside her circle.C. People’s fixed attitude toward female scientists.D. Widespread misconceptions about nature and nurtured.11. What does the image the author presents to her students suggest?A. Women students needn’t have the concerns of her generation.B. Women can balance a career in science and having a family.C. Women have more barriers on their way to academic success.D. Women now have fewer problems pursuing a science career.DShanghairesidents passing through the city’s eastern Huangpu district in Octobermight have astonished at an unusual sight: a “walking” building. An 85-year-old primary school has been lifted off the ground in its entirety and relocated using new technology named the “walking” machine.In the city’s latest effort to preserve historic structures, engineers used nearly 200 mobile supports under the five-story building. The supports act like robotic legs. They’re split into two groups which in turns rise up and down, imitating the human step. Attached sensors help control how the building moves forward.TheLagenaPrimary School, which weighs 7,600 tons, faced a new challenge — it’s T-shaped, while previously relocated structures were square or rectangular. Experts and technicians met to discuss possibilities and test a number of different technologies before deciding on the “walking machine”.Over the course of 18 days, the building was rotated 21degrees and moved 62 meters away to its new location. The old school building is set to become a center for heritage protection and cultural protection. The project marks the first time this “walking machine” method has been used inShanghaito relocate a historical building.In recent years,China’s rapid modernization has seen many historic buildingsrazedto clear land for skyscrapersand office buildings. But there has been growing concern about the architectural heritage loss as a result of destruction across the country.Shanghaihas beenChina’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings in the famous Bund district and 19th-century “Shikumen” houses in the repaired Xintiandi neighborhood has offered examples of how to give old buildings new life. The city also has a track record of relocating old buildings. In 2018, the city relocated a 90-year-old building in Hongkou district, which was then considered to beShanghai’s most complex relocation project to date.12. How did the primary school get moved?A. By reducing the weight of it.B. By using movable supports.C. By dividing it into several parts.D. By using robotic legs.13. What does the underlined word “razed” probably mean in Paragraph 5?A. Replaced.B. Burnt.C. Protected.D. Destroyed.14. What can we infer about the heritage preservation inChina?A. The use of advanced technology leads to growing concern.B. Shanghai is the pioneer in preserving architectural heritage.C.A number of old buildings have been given new life.D. Many historic buildings will be relocated.15. What is the passage mainly about?A. New preservation campaigns are launched inChina.B. New technology gives new life to historic buildings.C. A building inShanghai“walks” to a new location.D. “Walking machine” makes heritage protection simpler.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。

Knightscope says the goal is to reduce crime by half in areas the robots guard.William Santana Li is the chief executive officer of Knightscope. He says，"These robot security guards will change the world. Our planet has more than seven billion people on it. It's going to quickly get to nine billion people. The security equipmentthat we have globally is just not going to develop that fast. The company's Autonomous Data Machines can become the eyes and ears of law enforcement（执法）.""You want them to be machines plus humans. Let. the machines do the heavy and sometimes dangerous work and let the humans do the strategic decision-making work，so it's always working all together."The machines do not carry weapons but they have day and night video cameras which are able to turn 360 degrees and can also sense chemical and biological weapons.Some people may become concerned about their privacy, especially in connection with the video recordings. Some people may worry that such recordings will appear on the Internet. Eugene Volokh, a law professor at the UCLA School of Law, says the machines have to be used in the right way and it will be interesting to see how state laws deal with this kind of video.William Santana Li says there is a long waiting list for the robots in theUS. Workers in the company are working overtime to meet the demands of the market. At least 25 other countries are also interested in these robot security guards.1. What can this new tool do for humans?A. Make strategic decisions.B. Keep watching day and night.C. Carry heavy weapons.D. Stop crime autonomously.2. Why are some people worried about the new robots?A. Their privacy may be let out.B. The robots are very expensive.C. Robots will replace humans.D. They will be out of work soon.3. Which of the following can be the best title of the text?A. Robots Are Becoming More PopularB. Robots Contribute aLotto the WorldC. Robots Are in Great Demand NowD. Security Robots Could Help Cut CrimeBHow much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions（排放物）data?Does it matter at which stage in the lifecycle of a product the carbon is emitted? Research published in the International Journal of Environmental Policy and Decision Making offers a way to find out．Study participants view a carbon footprint label as similar to labels that have appeared on some existing products．The label shows the carbon dioxide emissions connected with their production, transportation, usage and disposal（清理）, thus showing the buyer the likely effect on climate change of buying a particular product．In the first group of studies, the research team proved that carbon emissions and a carbon emissions label would indeed play a role in consumer product decisions, although not as great a role as price．In a second set of studies, the team found that emissions connected with usage were most important to consumers followed by the transportation and disposal stages．The carbon footprint of the producing process was considered less important to consumers than the other stages in the product's lifecycle because it is outside the consumer's control．That is, the participants felt they were less responsible for carbon emitted during producing process．Consumers value recycling a product, but the researchers found that, overall, the consumers would preferproducers to offset（补偿）carbon emissions rather than having toaddressthe problem directly themselves．Consumers are increasingly concerned with climate change problems, and already carbon labeling is appearing on some products．"We find that participantsnot only take the carbon label into account when making product decisions, but they want detailed information on the label," the researchers explain．They suggest that companies should prepare for how carbon emissions labels might affect future consumer choice．4. Which of the following most affects consumer's choice?A. Labels．B. Price．C Packaging． D. Carbon footprint．5. About the carbon dioxide emissions in the product's lifecycle, which stage do consumers care most?A. Usage stage．B. Transportation stage．C. Disposal stage．D. Producing stage．6. Which of the following can best replace the underlined word "address"?A. Look into．B. Point out．C. Deal with．D. Run into．7. What can be inferred from the last paragraph?A. Companies should take carbonemissions more seriously．B. All products have been labeled with carbon emissions data．C. Producers will attach less importance to carbon emissions labels．D. Products labeled with carbon emissions data will have poor sales．CSonja Redding and her family were on their way home to Omaha, Nebraska, after a weeklong visit to Washington, D. C. with her two sons, one of whom, 5-year-old Xayvior, has autism(自闭症).Although all of the other flights had gone fine, Xayvior became angry during one of the flights, and Redding couldn’t calm him.“It felt like everyone on the plane was looking at us and got angry with my son, ” she wrote in a Facebook post after she got home. “I don’t know what to do when others just don’t understand that he is not just a kid with no discipline(自制力)，but a child with special needs who doesn’t know how to control himself.”The day was saved by Delta flight attendant(空乘人员)Amanda Amburgy. She tried to help Xayvior watch a movie, but when that failed, she offered to take him on a tour of the airplane.That worked, and soon the child was not only calm, but having a good time.“When they came back, Xayvior was much calmer and happier,” wrote Redding in the post，which now has 2,700 likes and over 500 shares. “I want to thank this Delta attendant. She didn’t judge, and she just showed love. We need more people like this in the world. ”It wasn’t long before Amburgy was told about the post.“ We’re there to help, and that’s what we want to do,” she said in an interview. “So, we always want to make anything easier for the family as well as other passengers.”She also shared what she felt when she read Redding’s story. “When I read it, it touched my heart. It’ssomething I would do for anyone on the plane, because that’s what I’m here for. It really made a difference in her life.”8. How did Redding feel on the plane?A. Tired.B. Uncomfortable.C. Very angry.D. Deeply afraid.9. What did Amburgy do to help the family?A. She asked the family to stay beside her.B. She asked the other passengers for help.C. She tried her best to calm the boy.D. She helped look after the other boy.10. Why did Redding post the story?A. To show her thanks.B. To help kids with autism.C. To get in touch with Amburgy.D. To share her travel experience.11. Which of the following words can best describe Amburgy?A. Proud.B. Honest.C. Hard-working.D. Warm-hearted.DWhen my friend suggested going to the op shop (二手商店)，instantly I thought “I hope no one I know sees me”. It was the same when my cousin commented on my new furniture and Japanese, fine-bone-china bowls and asked where I got them. They were from the local op shop but instead I said “from the antique shop”.Many people in my Greek-Cypriot community would look down on me if I said I shopped at the op shop. They may pity me, consider me poor, a failure. Immigrants sacrificed their families and homes for a better life. Buying a house and having enough money to live comfortably, to educate your children and see them also live comfortably, are a big part of the immigrant dream, But has this dream made us materialistic at the cost of our own planet?Our love for purchasing the latest trendy clothes or furniture, then donating them when we are tired of them has become normal. I was once like this. But after watching the documentaryThe True CostI learned donated clothes that don’t get sold are sent to developing nations, many of them ending up in landfills (垃圾填埋地). In addition, your new dress requires electricity and materials to make. But if you buy a second-hand dress, that’s oneless dress in a landfill and one less new dress to be made.A friend introduced me to op shopping only a few years ago. My firstitem was a dress she gifted me. It was lovely and I loved it. Nobody could tell it was second-hand. This opened me up to purchasing more second-hand high quality branded clothes. Once I visited a friend and was impressed by how she decorated her apartment. “It’s all second-hand,” she said. I couldn’t believe it. The truth is a lot of things sold at the op shop are in new or almost new condition. That’s when I made the decision to only buy second-hand things.Selling second-hand things isn’t anything new butwhat the planet needs is more buyers. There is so much excess (过量) production in the world. So stop feeling ashamed, and let’s get shopping.12. What kind of feeling is expressed in Paragraph 1?A. Pride.B. Embarrassment.C. Delight.D. Sympathy.13. Whatare many people in the author’s community like?A. They are probably materialistic.B. They care about the environment.C. They think highly of op shopping.D. They look down upon immigrants.14. What was the author encouraged to do after visiting her friend’s apartment?A. Watch the documentaryThe True Cost.B. Donate more to local charities.C. Avoid shopping too much.D. Stop buying new things.15. What’s the purpose of the text?A. To entertain.B. To advertise.C. To persuade.D. To describe.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。

2020届华南理工大学附属中学高三英语上学期期末考试试题及答案解析

2020届华南理工大学附属中学高三英语上学期期末考试试题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AThank you. It’s my great honor to be given this award.You cannot imagine that I have always been a late starter. Years ago, when I was 16, I took an important exam — GCE(General Certificate of Education), which turned out to be a failure. My dad was reading my report card and saw that my position in class was 29th, but the number in class was 29. It meant that I had achieved the distinction of being bottom of my class.I wasn’t lazy, and I was really trying. You can picture how I felt. Dad put his hand on my shoulder and said, “You can only do the best you can, but whatever you decide to do, make sure you love it.” He was a really sweet guy and a great man. I knew his attempt to hide his disappointment with some of his encouraging words. I was depressed for a week, but his advice was a wake-up call.Fortunately I love working with my hands, and I was good at two things: woodwork and art, and I really loved to draw and paint. I was quite talented. Dad strongly encouraged me to go to art school, which in those days wasn’t the obvious place that a father would suggest.So I got into Hartlepool College of Art. The college was a revelation (出乎意料), the passionate teachers there, who were extremely interested in the students, not just tolerating them but actually engaging with them. It was a world apart from my schooling until then. It’s extraordinary what an enthusiastic teacher can do, drawing the student out, lighting independence, and encouraging a design of your own future, rather than waiting for something to happen. I’m honored to have become one of these passionate teachers years later.My teachers inspired me, and thanks to my dad, here I am tonight. I think I should mention all the talents I have worked with over time, and to my kids and my wife Giannina, thank you.Thank you for this great award. I shall find a very special place for it.1. How did the author feel after taking GCE?A. Happy.B. Upset.C. Tired.D. Relieved.2. What didHartlepoolCollege of Art impress the author most?A. The teachers were strict with students.B. The students set good examples for each other.C. The teachers inspired students’ passion for learning.D. The students got prepared for their lessons independently.3. The author gave this speech to ________.A. share his career choiceB. explain his teaching methodsC. describe his life experienceD. show his appreciationBPlanned missions to the moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever research on solar storm timing.Scientists at theUniversityofReadingstudied 150 years of space weather data to look into patterns in the timing of the most extreme events,which can be extremely dangerous to astronauts and satellites. This new research on space weather timing allows predictions to be made for extreme space weather. Therefore, it could be used to plan the timing of activities, which could be affected by extreme space weather, for example, major space missions.The researchers found for the first time that extreme space weather events are more likely to occur early in or late solar cycles-such as the one just starting. The findings may have influences on the NASA-led Artemis mission. It plans to make humans return to the moon in 2024, but can be put off to the late 2020s.Professor Mathew Owens, a space physicist at theUniversityofReading, said, “Until now, the most extreme space weather events were thought to berandomin their timing. Though there is no set pattern of the events, this research suggests they are more predictable.”In the new study, the scientists used a new method applying statistical modelling to storm timing for the first time. Previous research generally focused on how big extreme space weather events can be, based on observations of previous events. Predicting their timing is far more difficult because extreme events are rare, so there is ly little historic data to identify patterns. The findings suggest that any major planned space missions , which is beyond the next five years, will have to consider the higher probability of extreme space weather late in the present solar cycle between 2026 and 2030.4. What can we learn about the study from the first two paragraphs?A. It has lasted just 150 years.B. It doesn't refer to space weather data.C. It shows space weather has no effect on astronauts.D. It makes it possible to predict extreme space weather.5. Why might the NASA-led Artemis mission be put off?A. To research solar cycles.B. To avoid effects of space weather.C. To meet the needs of the astronauts.D. To make humans return to Earth in 2024.6. What does the underlined word “random“ in paragraph 4 probably mean?A. Irregular.B. Easy.C. Limited.D. Changeless.7. What can we infer from the last paragraph?A. The study is useful for future space missions.B. The planned space missions should be put off.C. Extreme space weather will happen before 2026.D. Previous observations make no difference to the study.CAvi 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.

Since last year, Natalie, 15, hasbeen taking lost or thrown — away fishing nets and rope and transforming them into bracelets, rope art, mats, baskets and necklaces.Last year, Natalie was working on an assignment for her science, technology, engineering and mathematics (STEM) class. As part of the assignment, she learned about “ghost nets”, which are fishing nets that have been left or lost in the ocean by people who fish.“They have huge effects on our environment. They can kill coral reefs and many animals,” said Natalie. “46 percent of the Pacific garbage is ghost gear.” The Great Pacific Garbage is a huge collection of trash floating in the Pacific Ocean betweenHawaiiandCalifornia.Natalie told her mom she wanted to do something to help. She got in touch with a handful of charities, including the Sea Protection Society and Coastal Action.After getting some shipments of ghost nets and rope from those organizations, Natalie, with the help of her family, started turning thediscardedgear into new artworks. “We've made bracelets, rope art, mats, baskets, and we've made necklaces, which also use beach glass in them,” she said. Natalie then started selling the artworks online, the crafty buying and selling website.She donated all her profits-minus a small sum of change to cover supplies — to the charities that donatedfishing supplies to her. She's also been donating all the income from her non-profit business, called Nautical Waters, to charity. Natalie said she hoped to continue her passion for ocean life, with plans to study marine biology in university.12. How did Natalie help with ghost nets?A. By turning them into artworks.B.

Here’s what Janet told us:“Five years ago I used to live in a small town called Lemon Falls. I grew up and went to high school there. After I graduated I worked in a supermarket. Lemon Falls had a population of about 800 people, and I knew every single one of them. They all knew everything about me, too. You couldn’t do anything without everyone in town knowing about it. The first chance I got I moved to St. Louis and I love it. I don’t know as many people now as I used to, but that’s OK. I have a few good friends, and I see them when I want to. I kind of like beinganonymous. I’d never go back to Lemon Falls.”Troy Henson had the opposite experience. He and his wife, Darla, and their two children moved from St. Louis to Bloomfield three years ago. Here’s what Troy told us:“The best thing we ever did was get out of St. Louis. Don’t get me wrong; St. Louis is as good a place as any other city, I suppose — if you like cities, that is. We don’t. Both Darla and I grew up in St. Louis. We met at college and got married. Then the kids came along and life got difficult. We didn’t know any of our neighbors. We both had good jobs, but it always seemed like there was never enough money.

I'd waited my entire life to see this great French architecture, and experienced it in its full glory on a bright sunny day. Last night, I again cried for the centuries-old church while watching it burn.I hadn't expected to spend my evening that way. My friend and I were having dinner at a cafe a block or so away from the Notre Dame, choosing to skip going inside with the intention to go back the next day.However, we heard that it caught fire, so we left the cafe and ran towards the church, following heavy smoke from it, and soon we joined a nearly silent crowd. Some were praying, some were crying, but most were staring in disbelief at the disaster happening before us. The fire continued to get worse. About 400 firefighters were working to control the fire. We could see their flashlights shining as they inspected the front from a balcony.The Notre Dame is part of the heartbeat ofParis, I reflected on the experiences I've had there, from attending a bread market out front to admiring the beautiful windows and architecture inside. It is a spot that helps makeParismagical. And here we were, watching it burn down. It was too much to handle, but it was impossible to look away.About 9：30 pm, the gathered crowd spontaneously（自发地）began to sing Hymns（圣歌）to the church. We sang along with the group, feeling at once less like tourists and more like members of them. I hadn't imagined all that before.For hundreds of years, the Notre Dame hasseen the most joyous and the most terrible moments in the lives of both France and her people. And when everyone was able to become one emotional force, it showed that even in her darkest hour, the Notre Dame was still there to bring us all together.8. Why did the author cry for the Notre Dame for the first time?A. She was touched by its greatness.B. She was sorrowful to watch it burn.C. She was regretful for missing its glory.D. She was excited about French cultures.9. What was the author doing when the Notre Dame caught fire?A. Heading for a faraway cafe.B. Visiting a church with a friend.C. Eating nearby with a friend.D. Wandering along the street alone.10. What can we know about the fire scene?A. People expressed their sadness in different ways.B. People were nervously rushing in different directions.C. Hundreds of volunteers joined in putting out the fire.D. Firefighters kept people away with shining flashlights.11. What impressed the author most?A. The church allowed visitors to gaingreat experiences.B. Many foreign tourists became members of the church.C. The church survived disasters for hundreds of years.D. People were brought together to sing to the church.DHave you ever done something for someone else—knowing that your actions would solely benefit THEM and not YOU? Maybe you opened a door or donated blood or volunteered in a hospital’s ER during the pandemic. This is called a prosocial behavior. Humans engage in these types of behaviors all the time.But a question remains in science: Are we the only species who do this? As one of out closest s, chimpanzees have long been studied for signs of this. So far, research has provided mixed results on the question.Some studies show that chimps cooperatively hunt, share food and comfort each other. But one study came to a very different conclusion. The study used a controlled lab experiment where chimpanzees in enclosures were given two options: push a button to give food to themselves or push the button to give food to themselves AND a partner chimp. If they chose the latter, it was seen as a prosocial behavior. But the result is that chimps showed no special preferences for feeding themselves and a friend over feeding just themselves. Another study conducted by DeTroy, however, discovered a totally different result.Compared to previous controlled lab-based experiments, the setup for DeTroy’s research was very naturalistic. “We installed a button and a fountain into the chimpanzees’ outer enclosures. When an individual pushes the button, it releases juice from the fountain. However, since the button and fountain are approximately five meters apart, the individual pushing cannot directly drink from the fountain. And if any other chimpanzees are at the fountain when the button is pushed, they, and not the pusher, will be able to drink the juice.In this experiment, chimpanzees showed a willingness to act in the interest of others, with individual chimpanzees prepared to push the button without benefiting themselves.“It is really fascinating to see that many of the chimpanzees were willing to prosocially provide valuable resources to the group members even if they couldn’t benefit themselves from their behavior.” said DeTroy.Further research may reveal what lies behind their prosocial motivation. But for now, it’s safe to assume thatchimpanzees are not simply aping human behavior.12. Which of the following belongs to prosocial behaviors?A. Jack participated in voluntary work in the library just to earn credits.B. Mark turned to his classmate for help when feeling stressful in study.C. Tim guided a lost child back home on his way to an important job interview.D. Rose often interrupted the teacher to ask questions actively in the math’s class.13. What is the task of the chimpanzees in the lab-based study?A. Sharing food.B. Making a choice.C. Comforting others.D. Showing sympathy.14. How is DeTroy’s study different from the previous ones?A. It was based on controlled lab experiment.B. It gave juice to the chimpanzees as a reward.C. It offered the tested chimpanzees a natural surrounding.D. It provided a chance for chimpanzees to help their partners.15. What can we learn from DeTroy’s quotes?A. Chimpanzees can develop abilities to help others.B. Chimpanzees have acquired many human behaviors.C. Chimpanzees in the wild is cleverer than those in the lab.D. Chimpanzees displayed prosocial behaviors for certain rewards.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学年华南理工大学附属中学高三英语上学期期末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AMirroring body language is a way to bond and to build understanding, It is a powerful tool that we use without even knowing it.The most obvious forms of mirroring are yawning and smiling. When you seesomeone yawn, you are likely to yawn immediately. Smiling is also prettycontagious—seeing a smiling person makes you want to smile too.Mirroring body language is a nonverbal way to say “I am like you, I feel the same”. Research shows that people who experience the same feelings are likely to trust, understand and accept each other.Women have the natural ability to pick up and understand body signals. Therefore, it is not surprising that a woman is more likely to mirror another woman than a man is to mirror another man. That's why women are regarded as better talkers, even if they might not really have more close friends.It is interesting that when a man tries to mirror a woman's body language while she is talking, he may seem to her as caring, intelligent and attractive.Mirroring body language is an excellent way to build trust and understanding quickly. If you want to set up a connection with a new person, mirror his or her gestures, sitting position, tone of voice and talking pace. This will make them feel that there is something about you that they like.While mirroring body language gains you acceptance, you still need to take into consideration your relationship with the person you arc mirroring. If you are in a lower social position and are mirroring the body language of your boss, he will view you as arrogant. However, if you want to defeat those who are trying to prove superior to you, mirroring their body language will help defeat them and change their position.1. What does the underlined word “contagious” in paragraph 2 mean?A. Powerful to show one's feelings.B. Affecting each other.C. Attractive to the others.D. Being gentle to people around.2. When copying others, body language, one usually can ______.A. send wrong messagesB. hide true feelingsC. avoid misunderstandingD. win others, acceptance3. What might happen if you try to mirror your boss's body language?A. You will appear very attractive.B. It will help to soften his position.C. You will seem unacceptably proud.D. It willbe a good way to build trust.BChinese paleontologists (古生物学家) have determined that, about 47 million years ago, subtropical forests once existed on the high-altitude Qinghai-Tibet Plateau.The conclusion, which appears in a paper published on Tuesday, was drawn based on the large number of fossils found in theBaingoinBasinat an altitude of nearly 5,000 meters during the second comprehensive scientific expedition to the plateau.A joint team from theXishuangbannaTropicalBotanical Gardenconducted the research on the fossils. By combining the findings and models, the team recreated the climate and altitude that existed 47 million years ago, showing that the central plateau had an altitude of just 1,500 meters and an annual average temperature of 19℃, says Su Tao, a researcher from the tropical botanical garden and first author of the paper.“It was covered by thick forest and was rich in water and grass. It is fair tocall it the ‘ShangriLa’ of ancient times,” Su adds.The researchers have also found over 70 plant fossils, the majority of which are most closely related to plant life in today's subtropical or tropical regions.“This is enough to show that the central part of the now high-altitude, freezing Qinghai-Tibet Plateau had flourishing subtropical plants 47 million years ago,” Su says.The findings provide new evidence for the study of the evolutionary history of biodiversity and the evolution of the plateau's landscape, according to Zhou Zhekun, the paper's corresponding author and a researcher at the tropical botanical garden.Chinalaunched the second comprehensive scientific expedition to the Qinghai-Tibet Plateau in June 2017, 40 years after the first. Lasting up to 10 years, the expedition will conduct a series of studies focusing on the plateau's glaciers, its biodiversity and ecological changes, and will also monitor the changes in climate.4. How did the paper come to the conclusion?A. Through the observation of the Baingoin basin.B. Through the fossils found in scientific expedition.C. Through the drawing of a large number of fossils.D. Through the adventure on the Qinghai-Tibetan Plateau.5. What can be inferred according to Su Tao?A. The average altitude of the plateau was 1,500 meters.B. “Shangrila”means a place with abundant water and grass.C. The flourishing subtropical plants have covered the plateau.D. The fossils found by researchers are tropical or subtropical plants now.6. Where might the passage come from?A. The Times.B. The Wall Street Journal.C. Chinese National Geography.D. The Economist.7. What is the purpose of the passage?A. To instruct.B. To educate.C. To persuade.D. To inform.CDear Jack,I remember the moment— it truly hit me that your autism (自闭症) lasted forever. I had already mentally planned our trips up north with the boys. I was going to spend endless hours playing baseball with you— like Grandpa did with me.When we said goodbye to kindergarten I knew it was real. I spent some time being sad. Now you are 8. You still have no words. We have never had one of those father-son moments I pictured when you were a baby. But I'm learning that's OK. I still have unbelievable things to offer as your dad, even if they weren't the things I originally expected.You have taught me to be patient. You have taught me that it's OK to be different and to be sad when life doesn't go as planned. You have taught me that it is OK to talk about those feelings and fight for what is right. Stand up and say this is wrong, and encourage others to stand up for you and say the same.My job on this earth is to create a world for you and other kids like you. Be the voice you don't have, and build the kind of community which I want to see you grow up in. I used to shy away from contacting people with disabilities or just not consider them. Before you were born, I was so caught up in my own world that I probably wouldn't have even noticed. Now, I see things differently. I notice. You did that for me. And hope my example will do that for others.Your mom and I have spent 8 years trying to find your voice. And honestly, we don't know if we ever will. I promise you I will spend my life keeping you safe and making this world better for you.8. To whom is the text written?A. The author's son.B. The author's wife.C. The author's father.D. The author's friend.9. What can be learned about the author?A. He's at a loss what to do to help Jack.B. He's to blame for Jack s present condition.C. He has changed his attitude to the disabled.D. He hasn't accepted the reality up to now.10. How does the author sound in the text?A. Sympathetic.B. Caring.C. Regretful.D. Indifferent.11. In which section of a magazine may this text appear?A. Science.B. Entertainment.C. Sports.D. Relationship.DGrowing up as kids we are told to share our toys and notto be selfish. We also live in an age when discussing our feelings is encouraged. But when does it all become too much? With new crazes trending all the time, such as dance challenges and wearing a carpet as a dress, the question is: when can sharing become oversharing on social media?“Oversharing” has become associated with social media, but it isn'texclusiveto this platform. Imagine you head to a party and meet x k w someone. Within five minutes they have revealed private details about their life. While some of us may try to escape these people, according to marriage advisor Carolyn Cole, this form of oversharing could come from a strong desire to connect with someone. But how does this translate to social media?Dr. Christopher Hand, a lecturer in cyberpsychology (网络心理学），says the more details people disclose, the less sympathy we express when things go wrong. It seems that searching for sympathy by oversharing is generally considered as negative rather than the cry for help it could really be.However, Dr. Hand's research also seems to suggest that the more we post on a platform, the more socially attractive we become-provided that the posts that we bang out are positive. Even back in 2015, Gwendolyn Seidman PhD said that we should avoid complaining and being negative online. We should also avoid showing off,especially about our love lives. It makes sense-if your date is going “that well", would you really have time to share a photo with text?So, how can you know if you are oversharing? Well, why not ask your friends in real life. They would probably be happy to tell you if your posts about your breakfast or your complaints about your lack of money really are too much.12. What does the underlined word “exclusive" in paragraph 2 mean?A. Unique.B. Similar.C. Relevant.D. Fundamental.13. Why do some people prefer oversharing at parties?A. To draw others' attention.B. To satisfy others' curiosity.C. To remove negative feelings.D. To develop good relationships.14. Which of the following may Dr. Hand agree with?A. Sharing more details online can attract more sympathy.B. Oversharing negative experiences is equal to crying for help.C. Sharing negative posts can't help one become socially attractive.D. Oversharing isn't likely to happen online when things go wrong.15. According to the text, what should be avoided for online sharing?A. Reflecting on past bad manners.B. Showing a great many expensive goods.C. Writing a recipe for a balanced breakfast.D. Recording unforgettable moments with friends.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。
