2019-2020学年深圳市红岭中学高中部高三英语一模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AI started working with my hands at a young age. The youngest of five brothers, I took on the role as a “maintenance (维修) man” at an early age for our family’s small grocery store. Often my dad wouldn’t give me a clear idea of how something shouldbe done, so I just had to figure it out by researching or through trial and error.Fast forward to 2016 and those problem-solving skills would become the focus of Tippecanoe High School’s Homebuilding class. I knew I wanted to teach the students skills that went beyond just being able to hammer nails or cut pieces of two-by-fours. The problem was that we didn’t have the resources at the time to do much else. The idea of attracting some type of funding seemed very important. Designing, building and selling a tiny house on wheels seemed like the perfect project to accomplishthe task. I reached out to a number of local businesses and most of them responded with the greatest support for what x k w we were doing.This year we added a new element to the program. Through one of our partners, we were able to connect with the nonprofit Veteran’s Ananda Incorporated. Students in the Homebuilding class are leading the design and production of micro houses to be donated to this organization. The new partnership gives the students another focus to consider when designing and building the houses.There has been no shortage of students since our first year. Three years ago we had 41 students, the next 191, and this year it was limited to just over 160 students so we could have a safe and manageable classroom environment. The number of girls taking the class has risen steadily over the last few years as well. This class offers something for everyone and the skills are universal.1. How can we describe the young author?A. He opened a small grocery store.B. He did a lot of research in the lab.C. He enjoyed doing hands-on activities.D. He learnt about maintenance from his father.2. What do the underlined words “the task” in paragraph 2 refer to?A. Getting some financial support.B. Selling a tiny house on wheels.C. Reaching out to many local businesses.D. Offering the students some problem-solving skills.3. What can be inferred about the Homebuilding class from the last paragraph?A. Its size needs increasing.B. Itis popular with the students.C. It has caused some safety concerns.D. Its classroom environment is hard to manage.BOn September 7, 1930, Yuan Longping was born inBeijing. Fluent in English, his mother often read Friedrich Nietzsche's works to him. Influenced by his mother, Yuan Longping liked English,geography and chemistry at school. After graduating from university, he became a teacher in the countryside ofHunanin 1953.With lots of crop failures, nationwide hunger hitChinain the 1960s, making many people live a bad life. Yuan was sad and felt he must do something. Since the climate inHunanwas not friendly to growing wheat. He decided to devote himself to studying how to increase the production of rice, a basic food for over 60 percent of Chinese people. From then on, he began a lifelong connection with rice.Yuan Longping succeeded in growing the world's first high production hybrid rice (杂交水稻) variety in 1973, which could reach a yield of over 500 kg per more than 200 kg than before. For the next four decades, he continued to work on the research of hybrid rice. In 2020, hybrid rice developed by his team achieved 1,500 kg permuin two growing seasons, a new world record.Nowadays, the hybrid rice is grown in almost half ofChina's rice fields and its production accounts for 60 percent of the total rice production inChina. The hybrid rice production is 20 percent more than the common kinds , the yearly increase of which feeds up to 100 million people.In 2019, Yuan Longping, known as the “Father of hybrid rice”, was awarded with Medal of the Republic,China's highest honor.Yuan Longping's biggest dream in life was to develop more hybrid rice varieties, which could be grown all over the world to help solve the global food problem. So far, the hybrid varieties he developed have been grown in over 40 countries, including theUSA,BrazilandIndia.4. What do we know about Yuan Longping according to the text?A. He began to study hybrid rice in 1973.B. He received the highest honor inChinaat 90.C. He ever taught math in the city after graduation.D. He ever hoped Chinese would be free from hunger.5. How does the author mainly show the achievements of Yuan Longping in hybrid rice?A. By listing figures.B. By quoting reports.C. By imagining results.D. By explaining reasons.6.

What is the text mainly about?A. The life of Yuan Longping.B. The team of Yuan Longping.C. The honor of Yuan Longping.D. The education of Yuan Longping.CThere are 8.8 million blind people in India. In fact, there are 36 million blind people worldwide and a quarter of them are in India; however, many cases of blindness in India are curable. The poor in India have limited access to primary eye healthcare and often do not eat foods rich in micronutrients, like vitamins and minerals, which play an important role in maintaining good eye health.Many people worldwide are not even aware that they may have a vision (视力) problem simply because they do not get their eyes tested every year with a doctor, who tests for the functioning of the eye muscles (肌肉), as well as common diseases like night blindness. This exam is strongly recommended by experts because some changes in vision, which the patient may take longer to notice, can be found easily in this way.Certain simple changes in diet and lifestyle can ensure better eye health for you. These include drinking plenty-of water, not smoking, and eating brightly color1 ed and leafy fruit and vegetables. Wearing sunglasses protects your eyes from the sun, which damages otherwise healthy eyes. Learn about your family's eye disease history, and be on the lookout for any problem about your vision. Make sure that you see a doctor immediately for early intervention(干预) if you see any of these signs of worsening eye health.If you or a loved one needs to cure blindness or other eye diseases, turn to a crowdfunding (众筹) platform. A group of eye health caregivers have fundraised with crowdfunding platform ImpactGuru to raise money to perform operations on the eyes of blind women in south Asia. Running an online fundraiser enables both doctors and patients to find a way out of the dark. If you want eye care to develop, start a fundraiser today.8. Why are there so many blind people in India?A. There is a lack of eye hospitals in India.B. People pay no attention to their eyes at all.C. Poor Indians lack food good for eye health.D. The environment damages their eyes.9. What does the author suggest in Paragraph 2?A. Examining your eyes annually.B. Strengthening muscles every day.C. Raising the awareness of physical health.D. Attaching importance to self-examination.10. Which of the following may do harm to your eyes?A. Smoking a lot.B. Wearing sunglasses.C. Drinking much water.D. Watching brightly-color1 ed pictures.11. What does the author want to show in the last paragraph?A. How to start a fundraiser online.B. The importance of raising money.C. The role of crowdfunding in eye care.D. What should bedone to raise money.DLarry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children of his age were not even allowed to dive.After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limitedto a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them .Fortunately for him, a man offered to take him around the different spots for rry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken.The diving spots afforded such a wide range of fish and sea creatures that Larry saw more than thirty varieties of creatures.Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.12. In what way was this expedition different for Larry?A. His daughter had grown up.B. He had become a famous diver.C. His father would dive with him.D. His daughter would dive with him.13. What can be inferred from Paragraph 2?A. Larry had some special right.B. Larry liked the rented diving suits.C. Divers had to buy diving equipment.D. Ten-year-old children were permitted to dive.14. What can be learned from the underlined sentence?A. Larry didn’t wear a watch.B. Larry was not good at math.C. Larry had a poor memory.D. Larry enjoyed the adventure.15. What did Larry expect his daughter to do?A. Become a successful diver.B. Make a good diving guide.C. Take a lot of photo underwater.D. Have longer hours of training.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。

In some cases,babies,infants (婴儿)and teenagers have been admitted to hospital in north Wales alone.The Children’s Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child’s health as healthy eating and exercise,and children with poor sleep patterns were more likely to be fat.Statistics obtained (获得) under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.Children aged between 0 and 4 made up the highest number of inpatients (住院病人),with some newborns being treated for sleep-related problems from the day of birth.Vicki Dawson,who set up the Children’s Sleep Charity (CSC),said sleepless nights were putting both children and parents in anxiety. “Their weight and growth may also be affected as well as their mental health,”she said.Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn’t concentrate for long periods.Psychologist Amy McClelland,of Sleep Wales,saida common problem was that children were “over excited”before bed and that families should get back to basics. “Think 1950s family home. Dinner as a family,read,chat,a film maybe,lights off and then bed. ”She added.4. What’s the mainreason why children are short of sleep?A. Less exercise.B. Eating habits.C. Technology use.D. Sleep patterns.5. Who are the majority of the inpatients with sleep-related disorders?A. Infants.B. Teenagers.C. Teachers.D. Parents.6. What can we infer from what Amy McClelland said?A. Chatting and films make children sleep more.B. It is difficult for children to read before bed.C. Being too excitedis good for sleep habits.D. Relaxation has a bad effect on children.7. What is the best title forthe text?A. Ways to Treat Sleep ProblemsB. Sleep Problems of Welsh ChildrenC. Sleep Habits of Welsh ChildrenD. The Problems of Welsh ChildrenCThermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, like a free lunch. But the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermae-lectrices that work just as well. The work could pave the way for greener car engines, and other energy-generating devices.“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist. He notes there are still a few more steps before these materials can become high-performing. However, he says, “This will be used in the not too far future.”Thermoelectrics are semiconductor devices placed on a hot surface. That gives them a hot side and a cool side. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.Researchers have produced thermoelectric materials with increasing ZTs. The record came in 2014 when Mercouri Kanatzidis came up with a tin selenide with a ZT of 3.1. Yet the material was too fragile to work with. “For practical applications, it’s a non-star-ter,” Kanatzidis says.Getting through that door will still take some time. The tin selenide the team makes is mixed with Na,creating a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.Zhao’s team is now working on making an n-type version. Once successful, researchers should have a clear path to making a new generation of super-efficient thermoelectric genera-tors. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial smelters toscavengesome of the 65% of fossil fuel energy that winds up as waste heat.8. The first paragraph wants to tell us________.A. The wide use of thermoelectric generatorsB. The devices of current thermoelectric generatorsC. The reason why researchers make cheap thermoelectricsD. The greener car engines that contribute to environmental protection9. How does Li-Dong Zhao feel about cheap thermoelectric generators?A. Indifferent.B. Optimistic.C. Critical.D. Worried.10. What do you know about the research in 2014 from paragraph 4 and 5?A. It was far from a success for practical applications.B. A tin selenide with a ZT of 3.1 can be easy to work with.C. Researchers made an “n-type” version to make working devicesD. A “p-type” material made from the tin selenide conducts negative charges11. What does the underlined word “scavenge” in the last paragraph mean?A. Recycle.B. Produce.C. Clean.D. Increase.DDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock,because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.12. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.13. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.14. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music15. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by Music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 field technician who has worked at archaeological sites all aroundChina. Master Zhou iscredited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics(遗物) that wouldcrumblein other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic(新石器时代的) settlement near the Yellow River in the central province of Henan.It is not beauty that attracts visitors to Shuanghuaishu. At 5,300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims thatChinahas the oldest unbroken civilisation on Earth.Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge betweenChina's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof ofChina's 5,000 years of history.Foreigners complain about a lack of written records, Mr. Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders “can't keep using Western standards to apply to Chinese ruins,” he argues.8. What does the underlined word “crumble” in Paragraph 1 mean?A. Break.B. Start.C. Wait.D. Shine.9. Why does Shuanghuaishu attract visitors?A. It has appealing scenery.B. It has various precious treasures.C. It is of great historical significance.D. It is easily accessible.10. What is Mr. Wang's attitude towards foreigners’ view?A. Unconcern.B. Disapproving.C. Supportive.D. Not mentioned.11. What does the passage mainly talk about?A. Chinese history amazes the world.B. Chinese archaeology catches on.C. China follows its tradition.D.Chinadigs its past.DWe have most friends at the age of 26 afterhaving spent the first quarter of our lives building up our friendship circle, new research has claimed.The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.Forever Friends' relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our bestfriends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference."Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% todrift away fromchildhood friends.With growing pressure being put on friendship these days, it's important to make time for our friendship.12. How many friends can a 20-year-old college student make via Facebook?A. 22.B. 18.C. 12.D. 4.13.

While modem markets are more popular, floating markets still are huge attractions for local tourism. In Bangkok Floating Markets,Thailand, one of the most popular ones, any visitors can buy local foods and traditional hand-made souvenirs.Bregenzer Festspiele(Opera festival)The Bregenz Festival is held every year from July to August inVorarlberg,Austria. It has the world's largest stage on the water. The performances are different every year but they are usually united by one theme. The decorations(装饰)are very impressive and are worth seeing.Viva, ArtificialIslandArtificial islands are not something new. What makes this island special is that . it is floating. Viva is the largest out of three man-made islands along with Vista and Tera, all situated inSeoul,South Korea. The island weighs 2,000-tons and is technically a buoy(浮标).The island unfortunately is not carbon-neutral(碳中和)but it has solar panels which can generate electricity to power the hall, restaurants and shopping malls. MarinaBayFloating Platform StadiumThis stadium was built as a temporary solution while Singapore National Stadium was rebuilt. Now it is usedfor different sporting events, concerts, and festivals. In particular, it was once used for the opening and closing ceremonies during the 2010 Summer Youth Olympics.1. What can visitors do at Bangkok Floating Markets?A. Performing.B.Boating.C. Shopping.D. Swimming.2. What do you know about Viva?A. It is the biggest island inSouth Korea.B. It has the equipment to harness solar energy.C. It is the largest floating stage on the water.D. It is a man-made island only for low-carbon life.3. Which attraction should you choose to watch a basketball match?A. Bangkok Floating Markets.B. Bregenzer Festspiele.C. Viva, ArtificialIsland.D.MarinaBayFloating Platform Stadium.BThe founder of Earth Day was Gaylord Nelson, a U.S. Senator fromWisconsin. During the late 1960s, Americans witnessed the uninvited side effects of high productivity. Factories and power plants were sending out smoke and industrial waste while Americans were using petrol for their massive(大量的) cars, making air pollution almostsynonymous withthe nation’s development.What moved Senator Nelson to action was the 1969 massive oil spill inCalifornia, the largest in theUnited Statesat that time. The spill proved to be an environmental nightmare as it had a significant effect on marine life, killing about 3,500 sea birds, as well as marine animals such as dolphins, elephant seals and sea lions, fueling public anger. Inspired by the student antiwar movement at that period of time, Nelson found it an appropriate time to direct the energy of the students towards a fight for environmental protection. He decided that it was time to educate the Americans on the need to protect the environment. Thus Earth Day was born in 1970, and public environmentalawareness took centre stage.On 22ndApril 1970, millions of Americans took to the street and thousands of students marched to appeal for a healthy, sustainable environment. There was now a new synergy(协同作用) among different groups which had previously been fighting their causes related to the environment. Their fight for environmental conservation became so overwhelming that affected businesses were forced to follow environmental standards if they wanted to continue their operations.As it became more apparent that environmental issues were not just localized ones but a global concern, the year 1990 saw Earth Day reach out to many more around the world. Earth Day 1990 helped pave the way for the 1992 United Nations Earth Summit inRio de Janeiro, bringing together many nations for a united effort towards protecting the environment.4. Which of the following can replace the underlined phrase “synonymous with” in paragraph 1?A. familiar withB. opposite toC. different fromD. equal to5. Why did Nelson found Earth Day?A. To support students’ antiwar movement.B. To draw people’s attention to the seriousness of the oil spill.C. To arouse American’s awareness of environmental conservation.D. To educate Americans to protect marine life threatened by oil spill events.6. What can be inferred from the passage?A. Businesses would like to follow environmental standards.B. Earth Day united people to fight for environmental protection.C. It was the side effects of high productivity that led Nelson to take action.D. The 1992 United Nations Earth Summit made Earth Day known to more countries.7. The passage mainly talks about_______.A. how Earth Day came into beingB. why Earth Day was so significantC. who the founder of Earth Day wasD. what Earth Day meantto the worldCThe 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 and activity over the next decade, by 2030 they will hit 75 and enter a long period of decline for which few rich countries are ready.8. 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.9. 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.10. What’s the author’s attitude toward health-care spending on prevention?A. Unsatisfied.B. Subjective.C. Neutral.D. Active.11. What does the underlined word “met” in the fourth paragraph mean?A. dealt withB. come acrossC. satisfiedD. experienced.DOne-year-old Tallulah turned purple and stopped moving after the sweet became stuck in her throat. Her mum Leigh-Anne said the drama began during a visit to her grandma’s house when her grandparents gave her older kids some sweets.“Then at about 4:45 pm, Tallulah started to choke—we all went into a panic.”“It seemed like it went on for ages. Not one of us knew what to do.”“I rang an ambulance while my grandma and granddad tried to get the sweet to come up.”“Tallulah was panicking at first but then she started to go purple—she almost had no oxygen left in her.”With her daughter limp (无力的) and time running out, Leigh—Anne knew she couldn’t afford to wait for the ambulance to arrive.“The only thing I could think was to go out into the street.” She said.“I rushed out and screamed for someone to help while my grandma rushed out crying with Tallulah.”At exactly the moment, Caitlin, who is studying public services atRedcarCollege, was passing byQueen Street.She said, “I was waiting to go to work when I heard someone screaming for help, so I ran straight over.”The 17-year-old girl added, “Something just clicked and I went into auto mode. The little girl was completely limp, so I checked her airways and tilted (使倾斜) her over and started hitting her back. I turned her round and tapped on her chest, then after what felt like forever she coughed up the sweet and spat it out.As soon as she started crying I felt a huge relief. I was just so pleased I was able to help.”Caitlin was taught her lifesaving skills when she joined the Army Cadets four years ago.12. When did Tallulah get choked?A. While eating sweets.B. While enjoying a drama.C. While having a meal.D. While taking some medicine.13. Why did the family go out into the street?A. To buy some needed tools.B. To search for timely help.C. To get a breath of fresh air.D. To wait for the ambulance to arrive.14. Which of the following can best describe Caitlin?A. Brave and selfless.B. Kind and energetic.C. Determined and generous.D. Quick-thinking and helpful.15. What may be the best title for the text?A. First aid skill sounds important.B. Screaming for help makes sense.C. Eating sweets endangers baby girl.D. Heroic teenager saves baby girl’s life.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。

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 grandparentswere 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.

It is also one of those countries which have many traditions which modern times fortunately have not affected. Thailand is famous for its unique culture. It is well worth noting that Thai culture hasbeen handed down from one generation to the next.Thai Classical DanceThe inspiring culture includes local music and wonderful Thai dances. The dances of course have something to do with its deep-rooted Buddhist religion, fighting arts and beautiful clothing. Thai classical dance performances are generally performed by gracious (高雅的) Thai ladies wearing beautiful Thai local costumes.

However, sinceChina's economy took off in the last decade, street vendors have gradually disappeared from the streets and many of them opened shops of their own.Fast forward to today, street vendors have come into our sight again after cities such asChengduand Yantai succeeded in creating hundreds of thousands of jobs by giving street stalls permission to operate.China's tech industry was quick to jump on the street vendor trend, with tech giants including Alibaba, Tencent, Meituan and flocking todish outcheap loans, offer support and payment solutions to millions of owners of newly established small businesses.Ant Financial, Alibaba's fintech arm, promised its mobile wallet app Alipay will give interest-free loans to 30 million vendors, and 70 billion RMB of interest-free credit line to consumers to make purchases everywhere, including street vendors. provided 50 billion RMB worth of quality goods for street vendors, and provided each one of them with a maximum 100,000 RMB interest-free loan to stock up.Tencent's WeChat announced to offer payment solutions, marketing supports and even training for up to 50 million street vendors, with the end goal of digitally transforming them to increase their income.Guangzhoucity partnered with WeChat this month to hold a live streaming shopping festival to improve salesof local produce.

"Street Vendor Economy” Greatly Increases People's IncomeC. The Whole Nation Are Involved in a New Economy ModelD.China's Major Tech Companies Are Helping With "Street Vendor Economy”CThe secrets of dreaming are always interesting psychologists. It is generally acknowledged in the field that dreams people have during this time betweenchildhood and full adulthood, that’s around 30, are the strongest and most influential. Yet not enough is known about the repeated patterns of dreaming. Researchers are still trying to answer a basic question: How does dreaming relate to the life experiences and developmental challenges?G. William Domhoff and Adam Schneider, at theUniversityofCalifornia, help to answer this question by examining the lengthy dream series of two individuals, “Izzy” and “Jasmine”. Izzy provided a collection of 4, 329 dream reports from between the ages of 12 and 25, while Jasmine provided 664 dreams recorded between the ages of 14 and 25.Large collections of dreams like these pose challenges to researchers. Until recently, the means of studying dream series was to employ a team of recorders who take the time to code each dream for a predetermined(预先确定的)number of content categories, and then compare their results. Nowadays, digital technologies enable the analysis of language usage in dreams with high speed, accuracy, and objectivity. This marks a revolutionary advance in the science of dreaming. However,itcan only lead so far.To gain more specific and detailed insights, Domhoff and Schneider tailored word strings(词串)for each dreamer, mixing elements of traditional research with digital tools for analyzing large data sets. For Izzy these word strings included “family and s”, “celebrities” and “fantasy”, while the word strings they created for Jasmine included “familiar places,” electrical equipment” and “music”. The researchers used these word strings to identify connections between their dreams and real lives. Surprisingly, the results of the analysis revealed a great deal of consistency(一致性)and continuity in both sets of dreams. Izzy pays much attention to pop culture, and has affection for famous actors. Jasmine is an accomplished musician and performer.“The frequencies of dream elements show the intensity(强度)of the dreamer’s personal concern with that element in waking thought,” Domhoff and Schneider conclude. For anyone who still claims dreaming is merely random nonsense from the brain and mental world, these findings are hard to explain away.8. What do psychologists agree with about dreams?A. Dreams are influenced by life experiences.B. Dreaming is never nonsense from the brain.C. Dreams in one’s teens and twenties are strongest.D The patterns of dreaming are usually repeated.9. What does “it” underlined in paragraph 3 refer to?A. The collection of dreams.B. Research into dreaming.C. The digital method.D. The challenge for psychologists.10. How do the researchers conduct their study?A. By analyzing large data sets.B. By developing individualized word strings.C. By identifying the patterns of dreaming.D. By making comparison with traditional research.11. Which can be the best title for the text?A. New tech, new findingB. Dreams: reflections of waking realityC. Lives, languages, dreamsD. Life experiences: elements of mental worldDIn ancient times, Chinese used plant leaves or bird feathers as a fan during the summer time. This was the earliest form of the fan. The first real fan was made back in the era of Yao and Shun period thousands of years ago. Since then,Chinese-made fans have become a vital part of Chinese art and culture. At the beginning, the fan functioned as a tool to generate a current of air in the hot weather. Now electric fans such as ceiling fans and other technological breakthroughs have taken the place.Long ago, fans caught the attention of ancient Chinese artists by chance. Thereafter, a unique fan art gradually took shape in the history of Chinese culture. Fan art usually includes Chinese calligraphy, paintings, or poems on the sectors(扇区). Special skills are needed to write or paint on them.Due to its history and partly because of its unique shape, Chinese would soon develop the tradition of using fans as ornaments(装饰品). Fans are made in different sizes and different color1 s to meet the needs of each request. Other Chinese ornaments, such as the Chinese knot, the green jade, and the Spring Festival picture, are often combined in each design.The value of fans depends mainly on the materials used and the level of craftsmanship that is involved during the process. Feather, paper, jade, bamboo and silk have all been used as ideal materials to make fans. Ancient Chinese even made iron fans to serve as deadly weapons(武器)in Chinese martial arts. Fans made by famous craftsmen are often characterized by pretty designs and detailed workmanship, and thus become favorites of collectors. Fans with masterpiece fine art like calligraphy or paintings are even more valuable.12.What is the first paragraph mainly about?A. The origin of fans.B. The materials of fans.C. The popularity of fans.D. The production of fans.13. Why do Chinese use fans as ornaments?A. They are made of valuable materials.B. They reflect the beauty of Chinese culture.C. They convey literature works on the sectors.D. They are often combined with other ornaments.14. Which of the following makes a fan favored by most collectors?A. Its advanced function.B. Its complex character.C. Its artistic handicraft.D. Its various applications.15. What can we infer about the fan from the text?A. Chinese send fans to their friends as gifts.B. Chinese ornaments can meet different requests.C. Traditional fans have lost their functional value.D. The fan plays different roles with the change of time.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。

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 morningperson, 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 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.CThereare two days that set you on your path in life: the day you’re born, and the day you realize why you were born.Growing up south of Chicago in Harvey, Illinois, most people just had their heads down trying to make it from point A to point B. I was the same way, just going with the flow. I played basketball in high school because I was good at it and because other people thought I should until I discovered my talent.I give up basketball and started doing speeches. It wasn’t a popular decision but my grandfather told me to do what made me happy. I fell in love with comedy and performing. And when I discovered the passion, I realized why I was born.I knew I had something to offer —I knew that not only am I powerful, but I can make a difference.I realized a long time ago that my dream is not to be famous or rich. My talent is to entertain. But it’s more than that. I have the chance to reach people, to brighten days, to bring laughter and positive energy into lives and inspire. And I am grateful forit.Acting putting myself out there and having doors closed on me time and time again has taught me a lot about myself. I have learned to trust what I have to offer the world over momentary doubt. I’ve learned to put my faith over my feelings. And I've grown a tough skin. More importantly, I have learned there is a long way towards our goals and that when we put our talents and passion to work, we determine our value.Like a lot of places across the country, there’s poverty, crime, violence and unemployment in Harvey. Andgrowing up there, a lot of people have tragically low expectations for life. But I know that with the right opportunity and with help along the way, everyone can find their passion and go after it. My life is proof.8. What was the author born to do according to the text?A. Be a basketball player.B. Act and perform.C. Make speeches.D. Teach people.9. What does the underlined word “it” in Paragraph 5 refer to?A. Chance.B. Energy.C. Days.D. Laughter.10.

The Day I Realized What I Was Born to Do.DAs a rider, Anna Kiesenhofe’s Olympics victory might be a surprise. The winner of the road race at the Tokyo Olympics left the sport at the end of 2017 when she found herself out of contract (合同). She came into Tokyo without a professional team and left as an Olympic champion.The 30-year old began her cycling career in 2014 after running injuries that prevented her from continuing her pursuits of triathlon (铁人三项). She later joined a Catalan team and won the Spanish National Cup in 2016.The then-26 year old signedher first professional contract with Lotto Soudal Ladies for the following season. However, she ended her 2017 campaign in April and did not sign a contract for 2018, eventually taking a year off the bike. In 2019, Kiesenhofer came back to the sport as a rider, winning the Austrian national road race. Despite her results, Kiesenhofer sill had no professional contract while going into the Tokyo Olympics.Kiesenhofer was the first rider to attack in the Olympic road race, eventually forming a breakaway along with Carl Oberholzer, Omer Shapira, Vera Looser and Anna Plichta, which went on to reach a gap of 11 minutes. After Looser and Oberholzer were dropped, Kiesnhofer ataced her two remaining breakaway companions.After Shapira and Plichta were caught by the peloton (主车群), the rest of the riders seemed to believe that they were racing among themselves for Gold, not knowing that Remehofere was still in front.

Her story in particular has drawn the public’s attention given her young age. Social media users have been celebrating her brilliance and referring to her as pride of the country.Being the youngest of the team, Zhou Chengyu was born in1996 intheprovinceofGuizhou. She is certainly not “old” enough compared with her colleagues, but she is known at work as "Big Sister” as a sign of respect. Once in a 3-km running contest, she actually beat half of her male counterparts. Although work shifts are not uncommon at the Wenchang Spacecraft Launch Site, each shift requires tremendous courage because of the different background knowledge. However, for Zhou Chengyu, she experienced multiple positions in 5 launching tests and now she is the youngest commander at the site.Despite carefulness and high responsibility at work, she is just like her peers in normal life. Eating snacks and shopping are her favorite free-time activities. Her high school teacher remembers her as tough and determined. “She always had a dream of becoming scientist,” said her physics teacher.According to her colleague, Zhou Chengyu was very surprised when she found out shewent viralonline. She said that she was happy when she saw people online regarding her as the pride of the country, and yet she kept saying that she was “nobody but normal worker at a launch site” and there are a lot more people just like her going unnoticed while doing the hardest job to guarantee a better future for the Chinese space program.

An Ambitious CommanderCItaly's fashion capital is gray — not only because of the blocks of stone buildings,but also due to its often-gray sky, which traps pollution. ButMilannow wants to change it.The city has an ambitious plan to plant 3 million new trees by 2030 - a move that experts say could offer relief from the city's hot weather. Some projects have already contributed to environmental improvements. Architect Stefano Boeri’s Vertical Forest residential (居民的) tower, completed in 2014, aims to improve not only air quality but the quality of life for Milan residents. Boeri created a smallisland of greenery in the heart ofMilan, filling every balcony with plants that absorb carbon dioxide.“I think forestation is one of the best chances that we have today. It is one of the most effective ways we have to fight climate change, because everyone can plant trees, Boeri said.Damiano Di Simine, a member of the environmental group Legambiente , said the greenMilanproject will lower temperatures in a city where the nighttime temperature can be 6 degrees Celsius higher than in the surrounding area. City show thatMilanexperiences 35 hot nights a year. Because the city lies close to theAlps, Milin gets very little wind to lower the city's temperatures. "Planting trees will help this," Di said.TheVerticalForesthas attracted more than 20 species of birds. And the shade provided by the 800 trees and 15,000 plants means that residents rarely have to put on air conditioning, even in hot summers. TheVerticalForest's total greenery- can absorb 30 metric tons of carbon dioxide every year. The presence of green trees has a very important effect on people's health and psychological state, as has already been proved.8. What change doesMilanplan to make?A. Planting more trees.B. Creating a new fashion style.C. Pulling down more gray stone buildings.D. Doing more surveys to study global wanning.9. What's Boeri's opinion on the city's plan?A. It costs a lot.B. It is unpractical.C. It fails to attract people's attention.D. It is helpful to fight against climate change.10. What is Di Simine's attitude toward the city's plan?A. Doubtful.B. Supportive.C. Disappointed.D. Unconcerned.11. What does the last paragraph focus on?A. Specifics of the city's plan.B. Challenges faced by the city.C. The aim of theVerticalForestproject.D. The positive effect of theVerticalForestproject.DThe United Nations Educational, Scientific and Cultural Organization (UNESCO) included on December 17, 2020 China's Tai Chi on the RepresentativeList of the Intangible(无形的)Cultural Heritage of Humanity. The decision was announced during the online meeting of the UNESCO Intergovernmental Committee for the Safeguarding of the Intangible Cultural Heritage held from December 14 to19 inKingston, capital ofJamaica.“Born in the mid-17th century in a small village named Chenjiagou located in Central China's Henan province, Tai Chi is not only a kind of traditional Wushu integrated with slow movements and deep breathing, but is also deeply rooted in many areas of Chinese culture, such as medicine and philosophy,”Zhu Xianghua says, who is the son of the famous Tai Chi master Zhu Tiancai.Although it has spread to more than 150 countries and regions, attracting more than 100 million people to practice, the idea that Tai Chi is for the elderly has stopped many young people practicing the ancient Wushu. They think of it as a slow exercise, which is specially made and better suited for their grandparents. Instead, many young people are turning to the Indian practice of yoga(瑜伽)to relieve stress, which was placed on the UNESCO's List in 2019.In order to promote Tai Chi, joint efforts have been made from individuals and the Chinese government in the last decades. Xi'an Jiaotong University requires students to learn Tai Chi. Wang Yunbing, a professor in the university's sports center, stressed that Tai Chi is not only good physical exercise-researchers from the American College of Rheumatology find that it can help manage several diseases but is also conned ted to ancient Chinese eivilization. Since 2014, the World Tai Chi Championships have been held every two years by the InternationalWushu Federation. It provides a platform for communication and learning between the Tai Chi masters and Tai Chi lovers around the globe. In January 2020, Tai Chi became an official event in the 2026 Dakar Youth Olympic Games.12. What does Zhu Xianghua say about Tai Chi in paragraph 2?A. It originated from fast Kung Fu action.B. It was born around the 1750s in a village.C. It is related to other cultural fields ofChina.D. It integrates Chinese medicine and western philosophy.13. Why do some young people choose to practice yoga instead of Tai Chi?A. They think it easier to practice yoga to keep fit.B. The elderly stop young people practicing Tai Chi.C. They consider Tai Chi is custom-built for old people.D. Yoga was included in the world culture earlier than Tai Chi.14. What is the main purpose of the last paragraph?A. To promote contemporary Chinese civilization.B. To show many efforts made to popularize Tai Chi.C. To stress the importance of Chinese Tai Chi masters.D. To advise people to practise Tai Chi to cure diseases.15.Which of the following is the best title for the passage?A. Tai Chi Steps on the UNESCO's List.B. Tai Chi is Competing against Yoga.C.
