The natural history and cultural scenery of the area provide children with learning opportunities because they can enjoy the many wonders of this area.Fengjie Tiankeng Ground JointTiankeng Diqiao Scenic Area is located in the southern mountainous area of Fengjie County. The Tiankeng pit is 666 meters deep and is currently the deepest tiankeng in the world. The scenic spot is divided into ten areas including Xiaozhai Tiankeng, Tianjingxia Ground, Labyrinth River, and Longqiao River.

Located in the hinterland of Wuling Mountain. The Fuxi Cave in the scenic spot is about 3,000 meters long, with winding corridors, deep underground rivers, and color1 ful stalactites. The landscape is beautiful.Jinyun Mountain National Nature ReserveJinyun Mountain is located in Beibei District of Chongqing City, about 45 kilometers away from the Central District of Chongqing City. The nine peaks of Jinyun Mountain stand upright and rise from the ground. The ancient trees on the mountain are towering, the green bamboos form the forest, the environment is quiet, and the scenery is beautiful, so it is called "Little Emei". Among them, Yujian Peak is the highest, 1050 meters above sea level; Lion Peak is the most precipitous and spectacular, and the other peaks are also unique.Chongqing People's SquareChongqing's Great Hall of the People, one of the landmarks of Chongqing, gives people the deepest impression than its magnificent appearance resembling the Temple of Heaven. It also uses the traditional method of central axis symmetry, with colonnade-style double wings and a tower ending, plus a large green glazed roof, large red pillars, white railings, double-eave bucket arches, and painted carved beams.1.How deep is the Tiankeng Ground Joint?A.666mB.3,000mC.45kmD.1050m2.Which of the following rocks can you see in Youyang Peach Garden?A.LimestoneB.StalactiteC.MarbleD.Quartzite3.Which attraction is closest to downtown Chongqing?A.Fengjie Tiankeng Ground JointB.Jinyun Mountain National Nature ReserveC.Chongqing People's SquareD.Youyang Peach GardenBA wife’s level of education positively influences both her own and her husband’s chances of having a long life, according to a new Swedish study.In the study, researchers from the Swedish Institute for Social Research inStockholmfound that a woman’s level of education had a stronger connection to the likelihood of her husband dying over education. What’s more, they discovered that a husband’s social class, based on his occupation, had a greater influence on his wife’s longevity(长寿) than her own class.“Women traditionally take more responsibility for the home than men do, and, as a result, women’s levels of education might be more important for determining lifestyles－for example, in terms of food choices－than those of men,” say Srs. Robert Erikson and Jenny Torssander of the Swedish Institute for Social Research inStockholm.The results show that a husband’s level of education does not influence his longevity, but that men with partners who had quit studying after school were 25 per cent more likely to die early than men living with women holding university degrees. In turn, those married to women with university degrees were 13 percent more likely to die early than those whose wives had post-graduate qualifications.According to the researchers, a woman with a good education may not marry a man who drinks and smokes too much or who drives carelessly, and men with such habits may not prefer highly educated woman. Drs. Erikson and Torssander also suggest that better-educated women may be more aware of what healthy eating and good health care consist of.The findings suggest that education has a huge impact on how long and how well people live. It also reflects social factors, since educated individuals usually have better jobs, which allow them to afford healthier diets and lifestyles, as well as better health care.4. In this passage the author intends to ________.A. present the results of a studyB. encourage women to get higher educationC. analyze the relationship between education and lifeD. discuss why women usually live longer than men5. A woman with higher education is likely to ________.A. teach her children wellB. earn more money than her husbandC. marry a man without many bad habitsD. choose a husband with a higher degree than hers6. A wife’s education has more effect on a family than a husband’s because ________.A. women make more sacrifices to their families than men doB. most women have higher degrees than their husbandsC. most men marry women with higher degreesD. women have a leading role in the home life of most families7. We learn from the passage that ________.A. a man with a lot of education lives longer than one with littleB. educated wives tend to choose healthy lifestyles for their familiesC. highly-educated women don’t marry uneducated menD. a man’s longevity depends on not only his wife’s level of education but also his ownCWhen almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline（座机）?These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.Still, 55 percent of Australians have a landline phone at home and only just over a quarter（29%）rely only on their smartphones according to a survey（调查）. Of those Australians who still have a landline, a thirdconcedethat it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further13 percent keep it in case of emergencies. I think my home falls into that category.More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor（因素）— only 58 percent of Generation Ys still use landlinesnow and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who iscalling before we pick up the phone（using Caller ID would take the fun out of it）.How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?8. What does paragraph 2 mainly tell us about mobilephones?A. Their target users.B. Their wide popularity.C. Their major functions.D. Their complex design.9. What does the underlined word “concede” in paragraph 3 mean?A. Admit.B. Argue.C. Remember.D. Remark.10. What can we say about Baby Boomers?A. They like smartphone games.B. They enjoy guessing callers’ identity.C. They keep using landline phones.D. They are attached to their family.11. What can be inferred about the landline from the last paragraph?A. It remains a family necessity.B. Itwill fall out of use some day.C. It may increase daily expenses.D. It is as important as the gas light.DI was checking out at the supermarket counter on Wednesday night, ready to pay for my bananas, when all ofa sudden, fear came upon me. My wallet was gone. And I could only have left it one place: the G9 bus, from which I had gotten off minutes earlier and which was now speeding to some stops. The moment of realizing it was gone was followed by mental math. How much time and money would it cost to replace the credit cards, the driver's license, the expensive lipstick ($ 55!).Two hours after I was back at my house, I heard a knock on the door. My husband answered while I sat in thedining room on the phone with a credit card company. "Does Jennifer live here?" I heard someone say. In her hand was my wallet, without a penny missing. She left before I could offer my gratitude to her.After I posted the story, I heard from her boyfriend, who identified the good citizen as Erin Ball, a 26-year-old girl working for a trade organization.Once I figured out her, I called to thank her. She said she spotted my wallet and thought that it's more dangerous to go to a stranger's house than leaving the wallet with the driver, but she still decided to take the chance. "If I were in that situation, I would want someone to try to find me," she said. Ball doesn't find her actions particularly excellent. She added, "It's not hard to do small things for people."After Ball found my wallet, she decided to post a picture of my driver's license online before going to my house, trying to see if anyone knew me. No sooner had she left my doorstep than I got emails from two neighbors who recognized my face, both offering to help me find my missing property.Ball found my house on a bitterly cold night for which I was extremely grateful. Looking back, I'm not surprised someone had wanted to help a stranger. A warm current of honesty and harmony is running through this town.12. What do we know about the author according to paragraph 1?A. She missed the G9 bus.B. She paid for her bananas.C. She replaced the credit cards.D. She found she had left her wallet on the bus.13. Who helped the author find Ball?A. The G9 driver.B. The girl's boyfriend.C. The author's neighbors.D. The author's husband.14. What did Ball do first after finding the wallet?A. Ball called the author.B. Ball went to the author's house.C. Ball gave the wallet to the bus driver.D. Ball posted a photo of the author's driving license.15. Which of the following best describes Erin Ball?A. Humorous and kind.B. Generous and demanding.C. Honest and warm-hearted.D. Caring and outgoing.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。

a low - income area in Sydney's western suburbs - and its goal was to teach the kids how to create businesses and offer value to theneighborhood．At the end of the course，Sarah took the kids to the local area．She asked volunteers to share their business experiences - Kevin immediately put up his hand．His challenge was to trade his hot - dog selling service for free bread at a bakery．Although scared，Kevin was able to share his entrepreneur（创业）story with the shop owner and asked if he could exchange his service for some bread．Unexpectedly，the shop owner told Kevin how moved he was by his story and handed him some bread for free．By the end of theafternoon，his belief in himself and what was possible was at an all- time high．The following week，Kevin sold 70 hot - dogs in two hours and made over﹩200．Soonafter，he delivered public speeches in 20 schools，and was selected as part of his school's leadership team．Now he heads a business group working on how to increase potential customer base．All of his would not have been possible if Kevin had not found his passion andperseverance to improve himself，and those around him．The guidance and trust of his advisor also helped to kindle his enthusiasm to go after his goals and dreams in life．What were the kids expected to achieve in the Ready Set Go course？______A．To improve their test scores．B．To create a hot- dog business．C．To teach in low-income areas．D．To be beneficial to the local area．How did Kevin feel after visiting the local bakery？______A．Scared．B．Confident．C．Touched．D．Grateful．What does the underlined word " kindle" probably mean？______A．Inspire．B．Share．C．Continue．D．Express．Which can be a suitable title for the text？______A．On the Road to RecoveryB．Turning Failure into Success．C．Growing Wealthy through Hard Work．D．From Hopeless Youth Business Leader29. A woman held her phone tightly to her heart the way a church-goer might hold aBible．She was anxious to take a picture of an impressive bunch of flowers that sat not so far away，but first she had to get through a crowd of others pushing their way to do the same．The cause of this was Bouquets to Art，one of the most popular events at the de Young Museum in San Francisco．Flower sellers were asked to create flower arrangements that respond to pieces of art on display，from ancient carvings to contemporary sculptures．It's extremely attractive and also memorable，to the point that it has become a problem．In recent years，the de Young received more than a thousand complaints from people who felt that cell phones had spoiled their experience of the exhibit．institutions of fine art around the world face similar problems as the desire to take photographs becomes a huge attraction for museums，as well as something that upsets some of their patrons （资助人）．So the de Young responded with a kind of compromise：carving out "photo free"hours during the exhibition's six-day run．One common complaint about the effect of social media on museum culture is that people seem to be missing out on experiences because they are so busy collecting evidence of them．A study recently published in the journal Psychological Science suggests there is some truth to this．It finds that people who keep taking photos of an exhibit and posting them on social media rather than simply observing it，have；a hard time remembering what they see．But the issue is complex for the professionals running museums．Linda Butler，the de Young's head of marketing and visitor experience，acknowledges that not everyone wants a museum to be "a photo-taking playland．" Yet a lot of people do‑ and shebelieves that the de Young is in no position to judge one reason for buying a﹩28 ticket to bemore valid than another．"If we removed social media and photography，" she says，"we would risk becoming irrelevant．"What was the woman eager to do according to Paragraph 1？______A．To get her phone．B．To take a photo．C．To escape the crowd．D．To push ahead．How did the de Young respond to the dilemma？______A．By setting periods without photo-taking．B．By making the exhibition free of charge．C．By compromising with the government．D．By extending the free exhibition hours．The recent study finds that the use of social media in museums may ______ ．A．uncover the truthB．play a negative roleC．accumulate evidenceD．cause many complaintsWhich of the following may Linda Butler support？______A．Catering to visitors．B．Reducing admission prices．C．Reserving judgement in public．D．Banning social media and photography．30.Most autonomous vehicles test-driving in cities navigate （导航）by using 3-D mapsmarking every edge of roadside with almost centimeter-level accuracy．But few places have been mapped in such detail，which has left most areas like smaller townsinaccessible to those driverless cars．Researchers at the Massachusetts Institute of Technology （MIT）now have developeda new navigation system that guides autonomous vehicles without such accuratemaps．This technology can help driverless cars travel almost anywhere．The navigation system maps out a course down unfamiliar roads much as a human driver would by continually scanning its surroundings，with a laser sensor （激光感应器），to measure how close it is to the edges of the road．Meanwhile，the car also follows atool like a smart phone map app that provides directions to its destination，as well as information about the rules of the road，such as speed limits and the positions ofstoplights．Teddy Ort，a roboticist at MIT，test-drove a car equipped with thisnavigation system on a one-way road．It slowly traveled one kilometer without any human assistance．This system assumes that a car has a clear path down the road，but it can be paired with other existing computing technology to discover in-road obstacles （障碍），says Ort．The researchers also plan to build a version of this system which can spot markings painted on streets，so that the car can drive on two-way roads．"Self-driving cars with this navigation system may need other sensors to work in different conditions，"Alexander Wyglinski，and electrical engineer at Worcester Polytechnic Institute．"Since laser sensors don't work well in rain or snow，these cars might need additional imaging technologies to drive safely in bad weather．"What may be a problem for most driverless cars？______A．They fail in test-driving．B．Their maps are out-dated．C．They run in limited areas．D．Their guides are unreliable．What can we infer about the MIT navigation system？______A．It includes accurate maps．B．It removes in-road obstacles．C．It works by detecting the road，D．It features a smart phone app．What is the purpose of Paragraph 4？______A．To confirm the test-drive results．B．To indicate further research areas：C．To recognize scientists' achievements．D．To show the creativity of driverless cars．What is the main idea of the text？______A．Autonomous cars beat human drivers on country roads．B．Navigating self-driving cars may work in different conditions．C．Smart mapping technology adds to the functions of self-driving cars．D．A new navigation system helps autonomous cars drive remote roads．五、短文改错（本大题共1小题，共10.0分）31.假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文．文中共有10处语言错误，每句中最多有两处．每处错误仅涉及一个单词的增加、删除或修改．增加：在缺词处加一个漏字符号（八），并在其下面写出该加的词．删除：把多余的词用斜线（\）划掉．修改：在错的词下划一横线，并在该词下面写出修改后的词．注意：1．每处错误及其修改均仅限一词；2．只允许修改10处，多者（从第11处起）不计分．I

This time, he recommends some emotionally powerful books.The Book of Delightsby Ross Gay(2019)Gay's collection of 102 short but emotional stories, begun in mid-2016 and written in the order of time over a year in America, focuses on the careful observation of ordinary delights in daily life.

Paige Lewis.3. Where is the text most likely from?A. A diary.B. A brochure.C. A website.D. A magazine.BAt Aizo Chuo Hospital in Japan, employees greet newcomers, guide patients to and from the surgery area, and print out maps of the hospital for confused visitors. They don’t take lunch breaks or even get paid. Why? They’re robots!Robots have long worked in factories, helping to build cars and electronic appliances. But today’s robots don’t just do the jobs of people－they actually look and act a lot like people.Kansei, arobot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words. Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner”.Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations.The ability to interact is crucial for robots that will one day work closely with humans says robotics professor ChrisAtkeson. “ This will require robots to understand what you say and how you are feeling and respond with appropriate emotions, ” he told WR News.Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “ Right now, it only goes, ̒Ah, ah. ̓But as we develop its learning function, it will start saying more complex sentences and moving on its own, ” Asada says. “ Next-generation robots need to be able to learn and develop by themselves.”Intelligent robot will become more important in the future, as populations age and the number of human workers declines in many countries. “ We’re going to have many more old people and not enough young people to care for them,” says robot researcher Matthew Mason. “ Technology can help the old people live at home longer, instead of going to nursing homes.”4. According to the passage, what jobs have robots already performed?A. Giving advice, answering customer questions and planning events.B. Producing factory goods, building cars and greeting customers.C. Greeting customers, producing factory goods and performing surgery.D. Building cars, driving passengers and providing directions.5.

To predict the future uses of robots.6. How does the Kansei robot react on the word “fire”?A. Use languages to warn nearby humans.B Back up its memory files.C. Activate an automatic fire alarm.D. Produce a worried look on his face.7. In Asada’s opinion, the next step for robots will be to develop_______.A. the ability to learn independentlyB. the ability to understand human commandsC. the capacity to interact with humansD. the willingness to work togetherCI 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.DAge has never been a problem for 16-year-old Thessalonika Arzu-Embry. After all, she’s already got her master’s degree.The North Chicago-area teen started homeschooling at the age of 4. She began having an influence on otherssoon after. When she was 6 years old, she was an inspirational speaker at an organization called Tabitha House Community Service, which is for people who were forced to leave their homes because of earthquake, flood and other natural disasters.At the age of 11, she graduated from high school and then earned her bachelor’s degree in psychology in 2013. She completed those classes online as she was traveling for church events and leadership meetings.She doesn’t stop there, though. The teen plans to focus on aviation psychology (航空心理学) for her further study, a decision inspired by her father who is a pilot. She grew up around airplanes and took fights all the time. Her goal is to use it to help pilots deal with problems that could have deadly results once the plane takes off — a topic that has been in the news lately. For her, it’s a mix of two of her interests.In her free time, Thessalonika enjoys playing tennis, swimming and being active in her youth group at church. She also has three self-published books, which are on her site. Jump the Education Barrier is written to help students finish college, and in the future aims to help business owners with trends. Her third book The Genius Race is designed to help people to be talents in various areas of life.12. Which of the following is TRUE about Thessalonika?A. When she was 6 years old, she started homeschooling.B. She gained her master’s degree at the age of 11.C. She majored in science and technology.D. In 2013 she got her bachelor’s degree through completing courses online.13. What is her next plan according to the passage?A. Major in aviation psychology.B. Deliver inspiring speeches for church events and leadership meetings.C. Be active in her youth group at church.D. Write another book to help people to be talents.14. Why does she write the book Jump the Education Barrier?A. It aims to help people to be geniuses.B. It is intended to give students a hand to complete college.C. It is designed to arouse people’s awareness of psychology.D. The author hope to share her own experience with others.15. Which ofthe following can be the best title for the text?A.

2020年深圳外国语中学高三英语一模试题及答案解析
2020年深圳外国语中学高三英语一模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AA medical capsule robot is a small,often pill-sized device that can do planned movement inside the body after being swallowed or surgically inserted. Most models use wireless electronics or magnets or a combination of the two to control the movement of the capsule. Such devices have been equipped with cameras to allow observation and diagnosis, with sensors that “feel,” and even with mechanical needles that administer drugs.But in practice, Biomechatronics engineer Pietro Valdastri has found that developing capsule models from scratch (从头开始) is costly, time-consuming and requires advanced skills. “The problem was we had to do them from scratch every time,” said Valdastri in an interview. “And other research groups were redeveloping those same modules from scratch, which didn’t make sense.”Since most of the capsules have the same parts of components: a microprocessor, communication submodules, an energy source, sensors, and actuators (致动器), Valdastri and his team made the modular platform in which the pieceswork in concertand can be interchanged with ease. They also developed a flexible board on which the component parts are snapped in like Legos. The board can be folded to fit the body of the capsule, down to about 14 mm. Additionally, they compiled (编译) a library of components that designers could choose from, enabling hundreds of different combinations. They arranged it all in a free online system. Designers can take the available designs or adapt them to their specific needs.“Instead of redeveloping all the modules from scratch, people with limited technological experience can use our modules to build their own capsule robots in clinical use and focus on their innovation,” Valdastri said.Now, the team has designed a capsule equipped with a surgical clip to stop internal bleeding. Researchers at Scotland’s Royal Infirmary of Edinburg have also expressed interest in using the system to make a crawling capsule that takes images of the colon(结肠). One research group, led by professors at the Institute of Digestive Disease of the Chinese University of HongKong, is making a swimming capsule equipped with a camera that pushes itself through the stomach.One limitation of Valdastri’s system is that it’s only for designing models. Researchers can confirm their hypotheses (假设) and do first design using the platform, but will need to move to a custom approach to develop their capsules further and make them practical for clinical use.1. According to the passage, Valdastri and his team created the platform to ________.A. adopt the latest technologiesB. make their robots dream come trueC. help build specialized capsule robotsD. do preciser observation and diagnosis2. What does the underlined phrase “work in concert” mean in Para.3?A. Perform live.B. Run independently.C. Act in a cooperative way.D. Carry on step by step.3. What can be learnt from the passage?A. Valdastri’s system can’t provide a complete capsule creation.B. The modular platform is more useful than a custom approach.C. The capsules can move in human’s body automatically.D. It costs more to module the capsules on the board.BSummer heat can be dangerous, and heat leads to tragedy far toooften. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.For Bishop Curry, a fifth grader from Mckinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch (草图) of a device he called “Oasis.”The device would attach to carseats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the carseat, it would begin to circulate cool air. Curry alsodesigns the device using GPS and Wi-Fi technology, which would alarm the child’s parents and, if there was no response from them, the police.Curry’s father believes that the invention has potential. “The cool thing about Bishop’s thinking is none of this technology is new,” he said. “We feel like the way he’s thinking and combining all these technologies will get to production faster.” His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.In January, Curry’s father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis’potential that they have raised more than twice that — over $46,000.Curry’s father remembers the first time he saw his son’s sketch. “I was so proud of him for thinking of a solution,” he said. “We always just complain about things and rarely offer solutions.”4. What inspired Curry to invent Oasis?A. His narrow escape from death after being locked in a car.B. His knowledge of many children’s death because of car heat.C. The death of his neighbor’s baby after being left in a hot car.D. The injury of 37 children in his school in a car accident.5. What would Oasis do if it was hot in a car with a child?A. It would inform the parents or even the police.B. It would pump out the hot air in the car.C. It would sound the alarm attached to the car.D. It would get the window open to save the child.6. What does Curry’s father think is cool about Curry’s invention?A. It used some of the most advanced technology.B. It simply combined technologies that existed.C. It could accelerate production of new technology.D. It is the most advanced among similar products.7. Why did Curry’s father start a campaign to raise money?A. To conduct experiments to test the invention.B. To get other children devoted to inventions.C. To support a charity of medical aid for children.D. To get the patent and bring it to production.CRemember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be moresalutaryto your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds thatprovide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more effectively than fluoride.Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), andprotects against tooth decay.Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.8. The word “salutary” in paragraph 1 means?A. Beneficial.B. Harmful.C. Familiar.D. Useless.9. What can we know about the compound CBH in chocolate?A. It can help chocolate cure tooth decay.B. It can effectively stop teeth from decaying.C. It may protect teeth better than toothpastes do.D. It may soon replace most household toothpastes.10. How does chocolate fight tooth decay?A. By breaking down acids.B. By building up compounds.C. By fixing up tooth enamel.D. By fighting against bacteria.11. What's the main idea of the text?A. Chocolate plays the role of toothpaste.B. Chocolate protects against tooth decay.C. Chocolate is the best choice for teeth protection.D. Chocolate is healthier to teeth than other sweets.DTyphoons can be deadly — in 2013, Typhoon Haiyan, the strongest ever recorded, was responsible for 6,340 deaths—and cost billions in damages. Current forecast modelscan only predict these storms 10 days in advance, atmost, and they cannot precisely predict how intense the storms will become.An international team of researchers has developed a model that analyzes nearly a quarter of Earth’s surface and atmosphere in order to better predict the conditions that birth typoons.“The target problem of this study is how to foretell the birth of typhoons,” said paper author Mingkui Li, associate professor in the Key Laboratory of Physical Oceanography in the Ocean University of China and the Pilot National Laboratory for Marine Science and Technology (QNLM). “We specifically address three aspects: the beginning time, inner pressure and maximum wind speed.”The researchers also accounted for the influence of one variable(变量) on another, such as wind speed on sea surface temperature. This influence is well understood and accounted for in climate predictions and in weather forecasts, butithas not been fully applied in understanding how long-term climate affects day-to-day weather, according to Li. “We aimed to provide insights on the time scale that can be used to forecast typhoons in advance.”From their study, the researchers determined that a model with the ability to better understand the relationship between warm sea surface temperatures and weak wind movement— conditions that favor typhoon formation—could improve typhoon predictability.“Our goal is to develop a 10 to 30-day prediction system that will lead to seamless(无缝的) weather-climate predictions.” Shaoqing Zhang, paper author and professor in the Key Laboratory of Physical Oceanography, said.12. What is the problem with the present forecast system?A. It cannot foretell storms in advance.B. It is ineffective in accuracy and timeliness.C. It costs too much and causes great damages.D. It can hardly predict the intensity of typhoons.13. What does the underlined word “it” in paragraph 4 refer to?A. The variable.B. The climateC. The temperature.D. The influence.14. What is the purpose of the study?A. To advance the prediction system.B. To figure out the three main aspects.C. To know how climate affects daily weather.D. To understand the influence of the variables.15. Where is this text most likely from?A. Awork diary.B. A travel guidebook.C. A science magazine.D. A fantasy fiction.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。

Just choose one fit for you.• Paulinskill Valley TrailCheck out Paulinskill Valley Trail, filled with forests, wetlands, and small townsalong this 25- mile route. While the trail is mostly flat, you can do a quick ride. You're likely to catch sight of beautiful birds, considering more than 100 species find a home in the land near the path. Check out the trail in the fall - prime time for pretty sights.•AlaHele MakalaeOn theislandofKaui, you'll find a bike path with lots of beachy views that'll leave you feeling accomplished yet calm. The name translates to “The Path that Goes By Coast,” and, as you might guess, the seven-mile path hugs the shoreline. Start early enough and you'll witness an incredible sunrise to make it even more amazing,• TheCheaha RouteThis ride covers up to 126 miles, with steep climbs and extreme downhills along the way. So prepare for a thrilling ride - one that’s not necessarily for the inexperienced or those looking for an easy, casual ride. Along the route, you'll pedal through five towns. The journey is worth it, though, because you get some of the most scenic views in the state.• The Whitefish TrailFamous for its countless route options, whether you’re a new biker looking for smooth tracks or you have more experience and want to play around on rocky, more technical land, this bike path brings in lots of visitors. The 43-mile route offers beautiful green scenery. Around every comer, you’ll see a new jaw-dropping landscape, from glassy lakes to green mountains.1.

Various route options are offered.C. They have beautiful scenery.D. Different species can be found there.BWe asked four people who watched an online talk on technology and communication by Sherry Turkle for their opinions.Fred:The talk certainly gave me plenty of food for thought about how technology is changing our behaviour. People are constantly multitasking, whether it be emailing during meetings or texting in the checkout queue. It’s as if we can’t bear to miss out on what our online friends are up to, so we juggle the real and online world. My greatest concern is that we don’t give our brains a chance to switch off. It’sthese precious momentswhen we actually process information that helps us make important decisions.Jeremy:It was a fascinating talk and the speaker really hit the nail on the head with a couple of things. Take parental influence, for instance. How can we expect teenagers not to text while doing their homework when they witness their parents posting on social media while cooking the evening meal or waiting at a red light?Kath:So much of what the speaker said rang true. I honestly believe there’s a danger that the more connected we are, the more isolated we feel. I don’t think this is such an issue for my generation who’ve lived without technology for so long. We know how to be alone. But the under 20s are another kettle of fish. They’re so busy communicating that they never experience the feeling of solitude and run the risk of not learning how to enjoy their own company.Carl:I’m not sure to what extent I agree that people are more alone, but the way we communicate has certainly evolved. The speaker makes a good point about how we’re getting used to talking with machines like Siri or robots, which are totally lack of experience of human life. But despite such limitations, we seem to be expecting more from technology and less from each other.4. What does the underlined phrase “these precious moments” in paragraph 2 refer to?A. When our brains are free.B. When we emailing during meeting.C. When we texting in the checkout queue.D. When we juggle the real and online world.5. What suggestion may Jeremy give to the parents?A. Accompany their children when they are doing homework.B. Prevent their children using phone while doing homework.C. Set a good example for their children on using phone properly.D. Stop posting on social media in face of their children.6. What does Kath worry about the under 20s generation?A. They communicate more with others.B. They use more technology.C. It’s difficult for them to find companies.D. They don’t know how to be alone.7. What is Carl’s attitude towards the use of technology in communication?A. Favorable.B. Intolerant.C. Doubtful.D. Indifferent.CThe idea of growing food in a desert would make most people laugh but this is quickly becoming a reality. There are currently two desert farms in the world where quality vegetables are being planted cheaply and easily.Sundrop Farms, based in South Australia, uses experimental greenhouses to grow tomatoes, peppers and cucumbers. The biggest challenge of growing food in a desert, obviously, is the lack of available water. The researchers at Sundrop Farms have gotten aroundthis problemby using the sun to desalinate (淡化) sea water. It can also be used to control the temperature of the greenhouses.Without depending on limited resources such as land and fresh water Sundrop Farms has made farming a practice. This can increase the world’s food supplies. Another benefit ofthis kind of farming is that it can be done anywhere, thus reducing the costs of transporting food to distant locations. Yet another benefit is that it reduces the need for pesticides (杀虫剂).Another experimental desert farm is the Sahara Forest Project, which began in Qatar in December 2012. Greenhouses in the farm are cooled by saltwater. Solar power and other technologies are used together to help make vegetation (植被) grow in the desert environment. As deserts have expanded over recent years around the world due to global warming, this project could solve the problem.The result form the Qatar project were better than expected and in June of 2014, Jordan agreed to host another one. This will be much bigger than the Qatar project and the project members will have even more opportunities to test their experiments on a much larger scale. It is not clear yet that desert farming resents the future of farming but these projects have shown some success in the field.8. What does “this problem” in paragraph 2 refer to?A. Sea water is bard to purify.B. The desert is short of water.C. The temperature is high in the desert.D. Desert farms aren’t fit to plant vegetables.9. What is one of the characters of desert farming?A. It needs more pesticides.B. It saves delivery costs.C. It has a location limit.D. It solves food waste problems10. What can we know about the Sabara Forest Project?A. It lives up to expectationsB. It can help produce more foodC. It is started to prevent global warmingD. It uses technology to produce saltwater11. What can be inferred about desert farming from the last paragraph?A. It still has problems to solve.B. It represents the future of farming.C. Its early success has aroused interest in it.D. Its aim is to create more job opportunities.DJules Verne was born on 8 February1828 inthe French city of Nantes. From an early age, he had a fascination with exploration and discovery. When he was six, his teacher, Madame Sambin, told him stories about her husband, who disappeared while traveling the world on a ship 30 years before. She told her class that he was like Robinson Crusoe, a fictional castaway who lived on a desert island. Verne would later write stories about similar characters.In 1847, Verne was sent by his family to study law at a university in Paris, but he preferred to write novels, poems and plays. After graduating, he realized he wanted to write adventure stories based on science and technology.Thishad never been done before, but Verne was sure that it would be a success. His first story, Five Weeks in a Balloon, was published in September 1862. His career lasted for more than 40 years, during which time he wrote more than 60 gripping stories.To begin with, Verne wrote positive and optimistic books. Many of these were to be his most popularcreations. Although some included fantastical elements, they were usually based in scientific fact, making them believable. These happy stories weren’t to last. As he got older, Verne became less confident in the idea that science and technology were always good for the planet. His books started to include more scientists who used technology for their own-sometimes evil - purposes. Verne died on 24 March 1905, but new books continued to be published until 1919. These stories were based on ideas Verne had written about while he was still alive, but featured new characters and plots created by his son, Michel.In the 20th century, his books were translated into more than 140 languages and several successful film versions were released. His creations have been recognized as an inspiration for many scientists and inventors. Many of the futuristic ideas from his most popular books have since come true.12. What is the purpose of Paragraph 1?A To show Verne’s discovery.B. To offer the background information of Verne.C. To tell of the adventure of Sambin’s husband.D. To explain how Verne began his writing career.13. What does the underlined word “This” refer to in Paragraph 2:A. Writing novels, poems and plays.B. Studying law.C. Graduating from university.D. Wring adventure stories.14. What can be learned about Verne’s late works?A. They covered happy elements.B. They were unbelievable stories.C. They revealed Verne’s doubt on science.D. They were partly written by Berne’s son.15. Which of the following best describes Verne?A. Talented and productive.B. Popular and caring.C. Optimistic and generous.D. Friendly and honest.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。

作家批评的兴起，是近几年中国文坛的一个重要现象。
与学院派批评相比，作家批评并无明确的知识谱系，也少有自觉的方法论意识，但致力于文学批评的当代作家却以个性十足的艺术经验和文字表达，深刻改变着人们对文学批评的固有印象。
较之以知识求真为目标的学院派批评，作家批评更像是一场以经典重读为媒介、具有“创作”性质的艺术行为。
蕴含其中的思想活力和审美经验，有效反映出当前文学批评的话语变革。
如果深入思考这一批评话语的观念缘起，就会发现作家批评在冲击既有的批评格局之外，也暗含作家群体对重建文学生活的集体诉求。
文学之于现实社会，从来都不是附庸风雅的点缀。
不论在创作、评论抑或是作品传播与读者接受等方面，文学都能以其特有的力量潜移默化地影响我们的生活，这一点鲜明地体现在20世纪80年代的文学中。
那时的文学轰动效应，反映出文学对社会生活的巨大影响。
90年代后期始，随着互联网时代的到来，文学逐渐以另一种形式反映社会生活。
这种“文学生活”，不再局限于传统的创作、评论和传播模式，它借助文学与影视的联姻、传统媒体和新媒体的互补、文化资本的重新布局等手段，建构起一种新型的文学生活方式。
在这样的“文学生活”中，现实世界和虚拟空间的界限开始变得模糊，语言艺术和视觉艺术也相互交融。
“文学生活”的喧嚣扰攘与勃勃生机，同时成为这个时代最为醒目的文化标记。
2020年深圳外国语学校高中部高三英语一模试卷及参考答案
2020年深圳外国语学校高中部高三英语一模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AMy wife Hilary andI were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we saw a bear. The bear was thin and small, moving aimlessly.Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!" An aggressive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back the sign of an animal that is going in for the kill. And it was a cold April day. Thebear behaved abnormally, probably because of hunger.I held my camera tripod(三脚架)in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew 1 would not be able to hold it for long.Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that my bones were going to break.Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back towards-the forest,before returning for another attack the first time I felt panic.Obviously satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I'm proud that my family remained clear-headed when panic could have led to a very different outcome.1. How did the writer feel when faced with the brown bear?A. Fearful but confident.B. Nervous but brave.C. Upset but determined.D. Awful but hopeful.2. The bear finally went away after itA. got injuredB. felt safeC. found some foodD. took away the camera3. What does the author want to tell us?A. We should keep calm when troubles comeB. We should rise to the challenge when faced with difficulties.C. We should not risk ourselves in some dangerous areas.D. We should learn to take advantage of anything at hand when in trouble.BIf you’re looking for a reason to care about tree loss, this summer’s record-breaking heat waves might be it. Trees can lower summer daytime temperatures by as much as 10 degrees Fahrenheit, according to arecent study. But tree cover in US cities is shrinking (缩减). A study published last year by the US Forest Service found that we lost 36 million trees annually from urban and rural communities over a five-year period. “If we continue on this path, cities will become warmer, more polluted and generally unhealthier for inhabitants,” said David Nowak, a senior US Forest Service scientist and co-author of the study. Nowak says there are many reasons why our tree cover is declining, including hurricanes, tornadoes, fires, insects and disease. But the one reason for tree loss that humans can control is sensible development.Nowak says there is a downside to trees too, such as pollen allergy (花粉过敏) or large tailing branches in storms, and people don’t like sweeping leaves. But, he says, there are ways cities and counties can manage trees to help communities thrive (繁荣). Urban forests especially need our help to replace fallen trees. Unlike rural areas, it is very difficult for trees to repopulate themselves in a city environment with so much pavement and asphalt (沥青). “A lot of our native trees can’t actually find a place to drop a seed so they can regenerate,” explains Greg Levine, co-executivedirector of Trees Atlanta. “That’s why the community has to go in and actually plant a tree because the areas just aren’t natural anymore.”Nowak says the first step is caring for the trees on your own property (财产). “We think we pay for our house, and sowe must maintain it. But because we don’t pay for nature, we don’t need to. And that’s not necessarily true.”4. Why does the author mention “trees can lower summer daytime temperatures”?A. To tell the temperatures in summer are high.B. To explain the reason of tree loss.C. To tell trees are helpful.D. To introduce the topic.5. How can humans control tree loss according to Nowak?A. Develop cities in reasonable ways.B. Prevent fires form damaging trees.C. Improve climate to let trees grow.D. Decrease insects in cities.6. Why do forests in cities need our help?A. Because trees don’t grow in a city environment.B. Because native trees don’t drop seeds any more.C. Because trees in urban areas can’t regenerate naturally.D. Because humans want to plant more trees.7. What is the purpose of this passage?A. Describe the importance of trees in cities.B. Appeal people to protect trees in their surroundings.C. Ask people to plant trees with the author.D. Show the number of trees in theUSis declining.CNarasimha Das is on his way to feed 169,379 hungry children. Das is in charge of a kitchen in Vrindaban. The town is about a three-hour drive fromIndia’s capital,New Delhi. Das gets to work at 3:00 a.m. Thirty workers are already working to make tens of thousands of rounds of bread. It will be brought to 1,516 schools in and around Vrindaban.A Growing ProblemGoing to school is difficult for more than 13 million children inIndia. They must go to work instead, or go hungry. That’s whyIndiabegan the Mid-Day Meal Scheme, the largest school-lunch program in the world. A free lunch encourages children to come to school and gives them the energy they need for learning. The program began in the 1960s.The kitchen in Vrindaban is run by the Akshaya Patra Foundation. It is one of the lunch program’s biggest partners. “Just $11.50 can feed one child for an entire year,” said Madhu Sridhar, president of the Akshaya Patra Foundation.Lunch Is Served!The Akshaya Patra food truck arrives atGopalgarhPrimary School. Since the program started, the number of underweight children has gone down. The children get foods they need — as long as they finish what’s on their plates.8. What does Narasimha Das do？A. A waiter.B. A salesman.C. A cook.D. A shopkeeper.9. The kitchen in Vrindaban supplies food to ________.A. the poorB. school childrenC. college studentsD. the old10. Why is it difficult for children to go to school inIndia?A. Because they have to work to make money.B. Because there are not enough schools.C. Because there are not enough teachers.D. Because their parents refuse to send them to school.11. Which of the following about the Mid-Day Meal Scheme is NOT true?A. It is to encourage children to go to school.B. It has been carried out for about 50 years.C. It is run by Narasimha Das.D. It is the largest school-lunch program in the world.DThe race skywards began inAmerica. In the late1800s, industrialization had driven urban populations and land prices up, making tall buildings increasingly cost-effective, according to Carol Willis, director of theSkyscraperMuseuminNew York, “The very first tall buildings were office buildings that concentrated a work force, piled one on top of the other in order to make business very efficient, ”she says.Like all major changes in architecture, the trend wasunderpinnedby engineering. The development of steel framework, which could be used instead of load-bearing stones, made it easier and cheaper to build tall. The coming of the elevator, meanwhile, made living on higher floors far more convenient.Though similar in shape, today's skyscrapers (摩天大楼) look little like those built in the first half of the 20thcentury. This is mostly thanks to architecture's next major technological shift：the curtain wall.Postwar developments in manufacturing meant that huge panes of glass could be produced quickly and uniformly, and glass windows soon became the front of choice for high-rises. As well as allowing for greater floor space and more natural light, glass exteriors (外部) help. buildings resist greater windloads.There are now 191 completed skyscrapers that are at least 300 meters tall. But that doesn't mean our cities will grow taller indefinitely. While each additional story adds sellable floor space, construction costs also rise. All buildings reach a point where adding an extra floor will cost more money than it brings.“Every city wants to have this landmark that gives that sense of distinct culture, ”but it also needs places for people to live and work in urban settings“without the city sprawling (无序扩张), ”explains Hong Kong architect Simon Chan.The next big challenge facing architects goes beyond height：At a time when buildings and their construction account for more than a third of the world's energy consumption and contribute about 40% of greenhouse gas emissions(排放), there are new costs to consider.Whether it's employing more energy-efficient materials, encouraging natural air or using buildings themselves to generate solar or wind energy, reducing carbon emissions is the new frontier for many skyscraper architects.12. What does the underlined word“underpinned” in paragraph 2 probably mean?A. Created.B. Prepared.C. Suggested.D. Supported.13. What made living on higher floors much more convenient?A. The development of steel framework.B. Load-bearing stones.C. The use of the elevator.D. The curtain wall.14. What can we know from paragraph 5?A. Our cities will grow taller definitely.B. All skyscrapers are at least 300 meters tall.C. Construction cost rises as the stories increase.D. The profit for builders will be greater as the building becomes higher.15. What's the next big challenge facing architects?A. How to build the greenest building.B. How to build the strongest building.C. How to build the tallest building in the world.D. How to build the most comfortable building.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届深圳外国语学校高中部高三语文一模试题及答案一、现代文阅读（36分）(一)现代文阅读I(9分)阅读下列材料，完成下面小题。
哦，香雪铁凝如果不是有人发明了火车，如果不是有人把铁轨铺进深山，你怎么也不会发现台儿沟这个小村。
不久，这条线正式营运了，人们挤在村口，看见那绿色的长龙一路呼啸，挟带着来自山外的陌生、新鲜的清风，擦着台儿沟贫弱的脊背匆匆而过。
可是，记不清从什么时候起，列车时刻表上，还是多了“台儿沟”这一站，每晚七点钟，由首都方向开往山西的这列火车在这里停留一分钟。
这短暂的一分钟搅乱了台儿沟以往的宁静。
香雪总是第一个出门，隔壁的凤娇第二个就跟了出来。
哦，五彩缤纷的一分钟，你饱含着台儿沟的姑娘们多少喜怒哀乐！台儿沟没有学校，香雪每天上学要到十五里以外的公社。
公社中学虽然女同学不少，但她们的言谈举止，一个眼神，一声轻轻的笑，好像都是为了叫香雪意识到，她是小地方来的，穷地方来的。
“你上学怎么不带铅笔盒呀?”她们问。
每到这时，香雪的同桌就把自己那只宽大的泡沫塑料铅笔盒摆弄得哒哒乱响。
香雪的心再也不能平静了，她好像忽然明白了同学们对于她的再三盘问，明白了台儿沟是多么贫穷。
深秋，山风渐渐凛列了，天也黑得越来越早。
但香雪和她的姐妹们对于七点钟的火车，是照等不误的，她们仿照火车上那些城里姑娘的样子把自己武装起来，整齐地排列在铁路旁像是等待欢迎远方的贵宾，又像是准备着接受检阅。
火车停了，它对台儿沟表现了少有的冷漠。
香雪顺着车身一直向前走去，它的出现，使她再也不想往前走了。
她认清了，放在一个女学生面前的真是一只装有吸铁石的自动铅笔盒。
不知怎么的，她就朝车门跑去。
当她在门口站定时，还一把攥住了扶手。
香雪终于站在火车上了，这时车身忽然悸动，接着车门被人关上了。
香雪扑到车门上，看见凤娇的脸在车下一晃。
她拍打着玻璃，冲风娇叫喊着:“风娇！我怎么办呀！”列车无情地载着香雪一路飞奔，下一站叫西山ロ，西山ロ离台儿沟三十里。

Yet gold mining and coca farming have dealt a blow to its ecosystem. To limit additional development in the San Lucas area, the group helps coffee growers by linking them with processors from around the country.Colombia has more different kinds of living things than any other country except neighboring Brazil. In 2016, the Colombian government signed a peace deal with the Revolutionary Armed Forces of Colombia ending years of civil war. As a result, more land became accessible for use, with deforestation(毁林) coming along. Government information shows that in 2017, almost 220,000 hectares of forest were destroyed compared to around 124,000 hectares in 2015.To date, the project includes 10 families who farm 400 hectares of coffee plants, which costs about $77,000 dollars a year. WebConserva hopes that, in time, 200 families will be included. At that level, 20,000 hectares of untouched forest could be protected. In San Lucas, the families promise not to cut down trees to expand their crops or to hunt wild animals from the forests. In return, they receive $ 250 to $ 300 per 125 kilograms of coffee, an enviable amount there. Arcadio Barajas is among those taking part. His new coffee plantation(种植园) makes a barrier between cattle farms and forests where wild animals like the jaguar live and hunt. In this way, he doesn't have to kill wild animals to protect his cattle.Barajas said that pulling down the forest to plant coca and killing wildlife were against his will. Now he feelsthat growing coffee lets him be astewardof the land. "I'm taking care of the environment, the forest and the animals," he said.4. Why does WebConserva set up the project?A. To help local farmers make money.B. To expand areas of coffee growing.C. To link processors with coffee growers.D. To conserve biodiversity in the Mountains.5. What happened after Colombia’s civil war was over?A. Colombia helped many needy families.B. Colombia lost lots of areas of forests.C. Colombia started to save damaged forests.D. Colombia became more peaceful than Brazil.6. Which is probably a function of Barajas's coffee plantation?A. A method of protecting cattle and wildlife.B. A substitute for hunting of wild animals.C. A barrier between man and wild animals.D. A shelter for cattle against human hunters.7. What does the underlined word "steward" mean in the last paragraph?A. Farmer.B. Master.C. Guardian.D. Explorer.CTwo young brothers fromMalden.Massachusettswere in the spotlight Thursday after being named “heroes" by a national organization that recognizes young people doing great things. For the Bennett brothers, the goal of their work is nothing less than helping researchers find a cure for cancer. And their inspiration came from a friend.Thirteen-year-old Hany Bennett and his nine-year-old brother Heath run their business out of their family kitchen. "We're making lip balm（润唇膏），"Harry says. They got the idea two years ago when their friend, Timmy, was diagnosed（诊断）with cancer. brothers wanted to do something. We learned that cancer patients（lips and skin can get really dry because of chemotherapy（化疗），Hany says.A light bulb went off in both of their young heads,and " Bennett Brothers Balm was born. "We make lip balm, which is kind of like our main product/ says Heath. They also make and sell different body balms, all natural, allhandmade, while the profits benefit cancer research. "We've raised S 15,000/ Heath says.And with the great optimism of children, they don't just want to help；they wont to win. We want to find a cure. We want to help doctors find a cure, Harry explains, The brothers are also Gelding a team for the Light the Night Walk, to fight cancer."I think it's great to raise money and help people who have cancer," says Heath. Their parents play a big role as well, but it's the boys who provide the most enthusiasm with a message we can all learn from. "If you want to do something... do it," Harry says. "I just feel very glad that we're helping. It feels very good”，adds Heath.Harn and Heath just received the S 10,000 Gloria Barron Prize for Young Heroes. Hwy intend to save some of il for college, invest some of it in their business and give the rest to charity. And their friend Timmy? "He's doing great. He's all better, Harry says.8.

Two headsare better than one.C. Young kids can make a big difference.D. The longest journey begins with the first step.DWhen Jennifer Doudna was in sixth grade, she came home one day to find that her dad had lefta book titled The Double Helix on her bed. She put it aside, thinking it was one of those detective tales she loved.On a rainy Saturday, she picked up the book. As she sped through the pages, she became fascinated by thedrama, which encouraged her to explore nature's wonders. Even though her high school teacher told her that girls didn't become scientists, she decided she would.She worked with a biologist, Charpentier, to turn a curiosity of nature into an invention—an easy-to-use tool that can edit DNA. Known as Crispr, the tool will transform the human race. James Watson, the author of The Double Helix, later told her it was the most important biological advance: since he and Francis Crick discovered the structure of DNA.For this achievement, Doudna and Charpentier were awarded the Nobel Prize in Chemistry in 2020. Until now, only five women, beginning with Marie Curie in 1911, had won or shared the Nobel for Chemistry out of 184 award winners. When this year's prize was announced, Dr. Charpentier said it would provide a message specifically to young girls who would like to follow the path of science and to show them that women can also be awarded prizes.A few decades from now, if it becomes possible and sate to edit DNA, should we allow parents to improve the IQ and physical strength of their kids? Should we let them decide eye color1 ? Skin color1 ? Height? After helping to discover Crispr, Dr. Doudna has become a leader in considering these moral issues. That's the main message we should take from this Nobel: New technologies can be a huge benefit to the human race, but in order to make sure they are used wisely, it's important for people to understand them.12.

人类命运共同体理念反映了马克思共同体思想的时代精神，汲取了中国优秀传统文化的精华，与和平与发展的时代主题既一脉相承，又与时俱进，具有鲜明的时代内涵。
首先，人类命运共同体理念确立了一种新价值观。
当前，经济全球化与社会信息化程度日益加深，倡导对话协商、共享共建、合作共赢的新型国际关系成为世界各国的现实需要，当今国际社会发展所需的共同价值得到凸显。
“和平、发展、公平、正义、民主、自由，是全人类的共同价值。
”这种共同价值是对不同国家、民族价值观念的融合与升华，体现了当今世界的价值共识。
应当看到，共同的生活条件和共同的价值尺度，是联结共同体的纽带，而共同的价值观念则是共同体的精神存在方式和思想基础。
作为人类命运共同体的精神纽带，这种共同价值观打破了零和博弈、丛林法则等旧观念，明确了一种以和平发展、责任共担、合作共赢为特征的新价值观，成为改进全球治理体系的观念基础。
其次，人类命运共同体理念彰显了一种新时代观。
面对当今世界“百年未有之大变局”，我们应在人类文明的制高点上审视时代问题，对实现各国共同发展的现实需要做出当代的自我阐明。
正如黑格尔所言，“每一哲学都是它的时代的哲学”。
作为我们时代的思想，人类命运共同体理念体现了对时代发展变化的真知灼见，反映了对时代境况和发展取向的准确把握，从而彰显了时代精神的精华。
在当今时代，体现世界文明意识的纽带将各国联系在一起，“你中有我，我中有你”，为此必须增强互信、促进平等和共享，基于满足共同利益的需要，实现更加公平合理、包容互惠的全球治理。
最后，人类命运共同体理念倡导了一种新文明观。
人类历史是由不同国家、不同民族的文化融汇而成的波澜壮阔的画卷，不同文化主体在交流与对话中增进共识，人类未来的命运处于相互构成的境遇中。
人类命运共同体理念旨在消除现实生活中的文明壁垒，打破阻碍人类交往的精神隔阂，汇聚世界各国共同繁荣发展的文化合力，是创造人类文明新形态的中国主张。

China Satellite Navigation OfficeBWhen I was 9, we packed up our home in Los Angeles and arrived atHeathrow, London on a gray January morning. Everyone in the family settled quickly into the city except me. Without my beloved beaches and endless blue—sky days, I felt at a loss and out of place. Until I made a discovery.Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where the continuous crashing of skateboards left your head ringing .I loved it. I soon made friends with the local skaters. We spoke our own language. And my favorite: Safe. Safe meant cool. It meant hello. It meant don't worry about it. Once, when trying a certain trick on the beam（横杆）, I fell onto the stones, damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe. A few minutes later, when I landed the trick, my friends beat their boards loud, shouting: “Safe! Safe! Safe!” And that's what mattered—landing tricks, being a good skater.When I was 15, my family moved to Washington. I tried skateboarding there, but the locals were far less welcoming. Within a couple of years, I'd given it up.When I returned to London in 2004, I found myself wandering down to Southbank, spending hours there. I've traveled back several times since, most recently this past spring. The day was cold but clear: tourists and Londoners stopped to watch theskaters. Weaving（穿梭）among the kids who rushed by on their boards, I found my way to the beam. Then a rail—thin teenager, in a baggy white T—shirt, skidded（滑）up to the beam. He sat next to me. He seemed not to notice the man next to him. But soon I caughta few of his glances. “I was a local here 20 years ago,” I told him. Then, slowly, he began to nod his head. “Safe, man. Safe.”“Yeah,” I said. “Safe.”4. What can we learn about the author soon after he moved to London?A. He felt disappointed.B. He gave up his hobby.C. He liked the weather there.D.

Rutgers engineers have invented a cheap and easy way by transforming headphones into sensors that can be plugged into (插入) smartphones, identify their users monitor their heart rates and perform other services.Their invention, called HeadFi, is based on a small plug-in headphone adapter that turns a regular headphone into a sensing device (装置). Unlike smart headphones, regular headphones lack sensors. HeadFi would allow users to avoid having to buy a new pairof smart headphones with sensors to enjoy sensing features.“HeadFi could turn hundreds of millions of existing, regular headphones worldwide into intelligent ones with a simple upgrade (升级),” said Xiaoran Fan, a HeadFi primary inventor.A Rutgers-led paper on the invention, which results in "earable intelligence", will be formally published in October at MobiCom 2021, the top international conference on mobile computing and mobile and wireless networking. Headphones are among the most popular wearable devices worldwide and they continue to become; more intelligent as new functions appear, such as touch-based gesture control, the paper notes. Such functions usually rely on aiding sensors, such as accelerometers, gyroscopes and microphones that are availableon many smart headphones.HeadFi turns the two drivers already inside all headphones into a versatile (多功能的) sensor, and it works by connecting headphones to a pairing device, such as a smartphone. It doesn't require adding aiding sensors and avoids changes to headphone hardware or the need to customize headphones, both of which may increase theirweight and size. By plugging into HeadFi, a converted headphone can perform sensing tasks and play music at the same time.The engineers conducted experiments with 53 volunteers using 54 pairs of headphones with prices ranging from $2. 99 to $15 ,000. HeadFi can achieve 97. 2 percent to 99. 5 percent accuracy on user identification, 96.8 percent to 99. 2 percent on heart rate monitoring and 97. 7 percent to 99. 3 percent on gesture recognition.8. What does Xiaoran Fan think of HeadFi?A. Secure to operate.B. Simple to use.C. Easy to substitute.D. Convenient to store.9. What can we know about HeadFi according to the text?A. It can't work with headphones alone.B. It actually functions as a versatile sensor.C. It makes headphones larger and heavier than usual.D. It doesn't work when headphones are playing music.10. The figures are listed in the last paragraph mainly to show_________.A. the various functions of HeadFiB. the wide popularity of headphonesC. the great complexity of headphonesD. the excellent performance of HeadFi11. What can be the best title for the text?A. How to Use Headphones AppropriatelyB. Headphones Can Be Upgraded InstantlyC. How to Make Regular Headphones IntelligentD. New Uses Have Been Found in HeadphonesDAs one of the world’smost popular cultural mediums, cinema is at the leading position at the Taihu World Cultural Forum(论坛), an annual event that aims to improve cultural exchanges. So far this year, Chinese box office has already topped 58 billion yuan, the China Film Administration said. This indicates that China, the world’s second-largest movie market, is closing the gap with the United States, the world’s top cinema market.Cao Yin, director of the program center at China Movie Channel, said that China has 67,000 cinema screens. the most of any country, and the number is expected to increase to 80,000 by the end of next year. Saying that China has signed coproduction agreements with 22 countries (including the United States, Canada, Japan. India etc.) ,Cao added it has deepened cinematic exchanges between Chinese filmmakers and their foreign counterparts(同行).With the country’s huge native market, which produced more than 1,000 films in 2019, Hong Kong director Stanley Tong said he believes foreign filmmakers will increasingly seek cooperation with China. “International coproduction will become an important platform to send Chinese stories oversea and give us a broader vision of creation,” Tong said.Recently, over 80 percent of the world’s top 100 highest box-office titles have been action films. Tong said the films, in which plots are basically secondary to shining stunts (特技), is one of the easiest ways to appeal to foreign audiences. But it has been a decades-long struggle for Chinese filmmakers to sell their stories overseas. When asked what kinds of Chinese films would have the most global appeal. Yan Zhaozhu, chairman of the Taihu World Cultural Forum, said stories that address universal issues, such as environmental protection and climate change, are perhaps the best options.12. What is the purpose of the Taihu World Cultural Forum?A. To strengthen cultural exchanges.B. To build more cinemas in China.C. To invite more tourists to Taihu.D. To attract more international investment.13. What can we infer about Cao Yin’s opinion in Paragraph 2?A. Chinese box office has already overtaken the United States so farB. The screens of Chinese cinemas will be world-leading in the futureC. China has signed the most coproduction agreements with other countriesD. There will be more and more cooperations between Chinese filmmakers and other countries.14. How do Chinese filmmakers feel about selling their movies to the world right now?A. Easy.B. Disappointed.C. Challenged.D. Confused.15. What is the best title for the text?A. Box Office: Unclear FutureB. China: Top Second Movie MarketC. Cinema: The Leading Cultural PositionD. Chinese Filmmakers: Severe Competition Situation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。
2020-2021学年深圳外国语学校高中部高三英语一模试题及参考答案
2020-2021学年深圳外国语学校高中部高三英语一模试题及参考答案第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AIn September, something terrible happened on the west coast ofTasmania,Australia. As many as 380 pilot whales became stranded(搁浅) in shallow water there and later died. This might have beenAustralia’s largest stranding event on record, the BBC reported.But this large amount of whale stranding is not uncommon. For centuries, it has happened all over the world and has puzzled scientists. Scientists say the cause is often unknown. But they have offered many different explanations.Some say the whales chase small fish for food and end up in shallow water because they are not paying attention to where they are going.Others think the stranding has something to do with Earth’s geomagnetic field (地磁场). They say that a geomagnetic compass in whales’ brains controls their position. Unusual changes in Earth’s magnetic field can affect the whales’ compasses and send them in the wrong direction.Another explanation suggests that stranding is caused by the close relationships that whales have. Pilot whales travel in large groups. One lead whale might mistakenly lead the whole group to shallow water. “And if one gets into trouble, the others will not leave,” said Sheryl Gibney, a leading biologist fromNew Zealand. “Some will come in and try to help, they get trapped on the beach, then more will come.”The whales are trapped by mistake or out of sympathy(同情). Once they get stranded, they will likely die. According to the National Oceanic and Atmospheric Administration of theUS, less than 10 percent of all stranded whales survive.1. What do we know about the stranding inAustralia?A. It happened on theeast coast ofAustralia.B. It caused the death of over 300 pilot whales.C. It is commonly seen in September each year.D. It was the largest stranding event in the world.2. According to Gibney, the pilot whales are the animals that________.A. are kind to each otherB. are easy to lose directionC. are too huge to float in the seaD.are silly to follow the leading whale3. What is the story mainly about?A. How human activity has affected whales.B. What might cause whale strandings.C. How whales find their direction while traveling.D. What scientists are doing to save stranded whales.BA Bridge Linking Art and the AudienceAccording to a 2018 report, people aged between 16 and 24 make up about 15 percent of the population but only 10 percent of museum-goers. Similarly, people aged over35 go half as much as you would expect from their population size. We have reached the point of recognising the disconnection between art and the audience but haven’t yet determined how to bridge the gap. Two answers to tackling this challenge lie in telling a greater diversity of art histories and communicating these stories in more accessible ways.In 2018, a radio program called Art Matters was started with the aim of discussing art from a pop-culture viewpoint with topics that would engage younger and more diverse audience. It offers an accessible pathway to art history with conversations on different topics. Art history is about storytelling; art content shines when there is an effort to bring audience along for the discussion.More traditional institutions are paying attention. Recently theGettyMuseumissued a social-media challenge for people to recreate paintings using items they had at home. Users displayed incredible creativity, and the museum was flooded with submissions. This reaction proves that there is a potential desire for the audience to engage with art topics if the format is appealing. Since many people feelintimidatedand think that there’s a base level of understanding required to join the conversation, the Getty initiative serves as a reminder that there are many pathways to engaging with it.Another result of the Getty challenge was the exposure given to a diversity of artworks. The famous opera singer Peter Brathwaite, for example, made scores of attractive recreations highlighting centuries of black paintings. His efforts opposed the idea that there were not many historical paintings of black figures. It is extremely important that we do a better job of showing the complex and diverse stories that are represented in art.Social media have offered a platform for people who have not traditionally had a seat at the table. Anyone can recognise a gap in the field and address it. Accounts have gathered tens of thousands of followers. They are the proof that there is hunger to hear these art histories, and these themes work brilliantly for museum programming.But there is only so much that can be done without the museums and galleries changing meaningfully from within. We need to see a better balance of these stories represented in permanent collections. We also need a much wider diversity of people and interests represented on board. Ensuring that art-and writing and talking about art-is able to continue on the rising generation of storytellers, inside and outside of institutions, getting the funding and support they need to paint a brighter picture for the part.4. What challenge is the author trying to tackle?A. People doubt a great diversity of artworks.B. Fewer and fewer young people go to museums.C. Art appears too distant from common audience.D. Adult audience has a different understanding of art.5. What does the underlined word “intimidated” in Paragraph 3 probably mean?A. Tired.B. Worried.C. Annoyed.D. Surprised.6. In the author’s opinion, the museums and galleries should ________.A. make the art history stories accessible in a traditional way.B. change meaningfully for activities like the Getty challenge.C. limit the number of storytellers both in and out of institutions.D. improve the permanent collections by adding famous artworks.7. We can conclude from the passage that common audience ________.A. lacks the channels to understand and talk about art history.B. prefers to view artworks and hear art stories on social media.C. feels satisfied with people and interests represented on board.D. refuses to engage with diverse art topics and art history stories.CThere have been many fine films over the past several years aboutcharacters struggling with Alzheimer’s disease. But few of them have gone as deeply and frighteningly into the corners of adeterioratingmind as The Father,a powerful new drama built around a spellbinding performance from Anthony Hopkins.At this point in his long career,Hopkinswould seem to have exhausted his ability to surprise us, but his work here is nothing short of astonishing. His character, also named Anthony, is 80 years old and has dementia. At the beginning of the movie, his daughter, Anne — played by Olivia Colman — stops by hisLondonapartment to check on him. Her father's condition has taken a turn for the worse, and his temper has become severe enough to send his latest live in nurse packing. Anthony is stubborn and defiant and insists that he can manage on his own. But that's clearly not the case, given his habit of misplacing his things and his inability to remember names and faces, Anne's included.As The Father goes on, the more it becomes clear that it's his own mind that's playing tricks on him. What makes the movie so unsettling is the way it wires us directly into his subjective experience, so that the foundations of the story seem to shift at random from scene to scene. A man suddenly appears in the apartment, claiming to be Anne's husband, which is odd, since just a few moments earlier, Anne seemed to be single. Anne goes out shopping for groceries, but when she returns, she's played not by Olivia Colman but by another actress, Olivia Williams. Even the apartment itself begins to shift. You notice puzzling differences-wasn't there a lamp on that hallway table just a moment ago?The story in The Father may be complicated but it's also heartbreakingly simple: man grows old and loses his memory, and his daughter, after lifetime of love and devotion, must begin the long painful process of saying goodbye.Hopkinsshows us Anthony's struggle to keep his sense about him. It's a striking performance-and an impossible one to forget.8. What does the underlined word “deteriorating” mean in the first paragraph?A. Worsening.B. Narrowing.C. Recovering.D. Improving.9. What do we learn about the character Anthony in the movie?A. He can take care of himselfB. He drives away the nurses.C. He is easy-going and forgetful.D. He lives with his daughter all the time.10. The shift of scenes in the movie is designed to .A. build the dramatic tension in the family.B. show off the well-designed story line.C. frighten the movie-goers with mysterious plot.D. involve the viewers into thedisordered memories.11. What does the author think ofHopkins?A. He has run out of his talent.B. He is not suitable for the roleC. He masterly plays the old man.D. He presents an odd performance.DIt was five years ago that something unforgettable happened. My wife and I celebrated our 40thwedding anniversary that year. It was a lovely event hosted by our sons for us. My wonderful friends from the past surprised us with gifts and congratulations. Our gift to each other was a driving trip out west. We drove fromOntariointoAlberta, then southward intoGlacierNational ParkinMontana, and continued toYellowstoneNational Park.It was a cold spring day, and theBeartooth Highwayhad opened for the season just days before. Alongside the road, there was still a great amount of snow there. The scenery was so impressive that we made lots of stops to record memories with my camera. At the highest point of the highway, I stopped at a lookout to catch the amazing views, with my wife in the centre of my camera lens.There were not many cars on the road. Sometimes, cars with energetic young tourists passed by. And then we heard a motorcycle in the distance. The driver of the motorcycle, who wore dirty clothes, parked behind our cars. As he approached us, his only words were, “Give me your camera and get over there with your wife.” I must admit I felt nervous that we might be robbed where we just created some beautiful memories. Surprisingly, he just took a picture of us, handed back my camera and rode off before we could express our gratitude. The photo he took is one of the most valuable and prized of our trip.I learned my lesson somewhere I least expected it. We should never judge a man by his appearance. If the motorcycle driver reads this story and remembers the situation, we would like to say “Thank you” to him.12. According to the passage, what do we know about the trip?A. It was taken by train to the west.B. It was a suggestion from their friends.C. It was in the late autumn five years ago.D. It was a gift for their wedding anniversary.13. Why was the author nervous when the motorcycle driver offered to take a picture?A. He could have lost the camera.B. His wife might not be satisfied with the view there.C. The motorcycle driver would borrow the camera.D. The motorcycle driver might not be good at the taking pictures.14. Which of the following best describes the driver of the motorcycle?A.

Seeing is believing.C. Don’t judge a book by its cover.D. The longest journey begins with the first step.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。

Our ability to walk upright has allowed humankind to travel great distances and survive changing climates, environments and landscapes.Countless scientific studies have found that walking is really good for us and this simple act can provide a number of healthimplications, which help people live longer. In fact, a walking routine, if done properly, might be the only exercise people need.How much walking should one aim for? You’ve likely heard we need 10,000 steps a day. That’s about 5 miles. But contrary to popular belief, this recommendation doesn’t come from science. Instead, itis from a 1960s advertising campaign to promote a pedometer (计步器) in Japan. Perhaps because it’s a round number and easy to remember, it stuck.Since the 1960s, researchers have studied the 10,000-steps-a-day standard and have turned up mixed results. Although 10,000 steps is certainly a healthy and worthwhile goal, it’s not fit for all.For instance, a recent Harvard University study involving more than 16,000 senior women found that those who got at least 4,400 steps a day greatly reduced their risk of dying early when compared with less active women. The study also noted that these benefits continued up to 7,500 steps. This 7,500 mark isn’t surprising: It’s similar to common public health recommendations, such as the Centers for Disease Control and Prevention’s recommendation of 150 minutes of moderate (适度的) physical activity a week for adults.4. What does the underlined word “implications” in Paragraph 2 refer to?A. BenefitsB. Problems.C. Habits.D. Manners.5. Where does the 10,000-steps-a-day standard come from?A. A Harvard University study.B. Science research on health.C. A pedometer advertisement.D. Public health recommendation.6.

The more you walk a day, the healthier you will be.B. We can benefit from continuous and proper walking.C. Walking upright helps humankind to explore the world.D. Advertisements can always tell us some scientific suggestions .CWater keeps us alive. When it runs out, we have a problem.About one out of four people on the planet are facing a shortage of water. Seventeen countries around the world are dealing with high-water stress. This means they are using almost all the water they have access to. Many are dry countries. Some waste much of their water. Some may currently use too much of their groundwater that they should be saving. Several big cities face acute shortages. These include Sao Paulo, Brazil; Chennai, India; and Cape Town, South Africa. A year ago, Cape Town faced nay Zero-the day when all its dams would he dry.Climate change adds to the risk of water shortages. Rainfall is less steady. The water supply becomes less reliable. The days grow hotter. More water evaporates(蒸发)from lakes and rivers even as demand for water increases. By 2030, the number of cities in the high-stress category may have risen to 45 and include almost 470 million people.All over the world, farmers compete with city residents for water. Rich urban places, such as Los Angeles, use too much water for pools and golf courses. But the worst problem is the growth of cities. Bangalore, India, for example, had a few years with little rain. It built over its many lakes or filled them with city waste. The lakes are no longer the rain water storage tanks they once were. Bangalore now imports water. A lot of the imported water, however, gets lost on the way to Bangalore.To address this issue, what can be done? First, cities can plug leaks in their water distribution system. Wastewater can be recycled. Rain can be harvested and saved for hard times. Lakes and wetlands can be cleaned up and old wells can be restored. And farmers can switch from water-intensive crops like rice to less-thirsty crops like millet(小米).Experts are looking at ways to reduce the number of people on the planet. They are looking at ways to reduce the size of cities. They are looking for ways to encourage people, factories and farmers to use less water.8. What can we know from Paragraph 2?A. A quarter of the world's population is living with water shortages.B. Nearly all countries are facing acute water shortages now.C. Underground water should he used to meet the water demand.D. Measures have been taken to deal with the water shortage in India.9. What is the main idea of the third paragraph?A. Rainfall is not as steady as before.B. Climate change may lead to water shortages.C. The water supply relies more on rainfall.D. Hotter weather changes the water demand.10. What can farmers do to deal with water shortage?A. Plug leaks in the water distribution system.B. Clean up lakes and wetlands and restore wells.C. Reduce the number of people in the cities.D. Grow less-water consumption crops instead.11. What will be discussed if the passage continues?A. How to prevent from climate change.B. How to inspire people to save water.C. How to recycle wastewater in citiesD. How to make people get access to clean water.DWhy can friendships be hard? Because often people aren't as honest and open as they should be. Sometimes, people end up getting hurt.Most problems with friendships come up because people are just too selfish to care about the things that their friends need. They care about their own needs much more, which makes it hard for friendships to work. However, being selfish is part of human nature. A person is put together in order to take care of himself and his own needs, not necessarily those needs of other people. Even though being selfish is something that all humans are born with, it is something that everyone should guard against.The best thing to remember when you are a friend to anyone is that you need to treat your friend the same way as you'd like to be treated. This is wonderful advice for a friendship, because it is really the only way to make sure that you are giving your friend everything you would want to be given in a friendship. Whenever you have a question about how you should treat a friend, it is easy to find an answer simply by asking yourself what you would like your friend to do for you, if he or she is in your shoes.Even if you're always thinking about how you'd like to be treated, and your friends are too, there are issuesthat come up from time to time in each friendship, and it is important to understand how to deal with these issues so that you can build stronger and healthier friendships. Issues like friends getting boyfriends or girlfriends and not spending enough time with their friends, or even friends finding new friends and leaving old friends behind are issues that will probably come up with one or more of your friendships. It is important to know how to deal with these issues so that you can keep your friends and make new ones. No one wants to have a broken friendship.12. Why may problems with friendships appear?A. One is selfish.B. One is alone.C. One is too anxious.D. One is too busy.13. What's the first and most important thing to be other people's friend?A. Not to hurt your friends' feelings.B. To give your friends whatever you have.C. To treat your friends as fairly as possible.D. Not to think of your own needs any more.14. What is the text mainly about?A. The Meaning of FriendshipsB. The Importance of FriendshipsC. The Advantages of FriendshipsD. The Problems with Friendships15. What may follow the last paragraph of the text?A. How to make many friends.B. How to keep friends happy.C. How to treat friends correctly.D. How to solve friendship issues.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。
