AMany college students choose to study abroad to get life experience and, more importantly, competitive competence for their future career and life. Considering the high tuition rates in universities in the UK and US, many students nowadays are choosing less common destinations to fulfill their overseas study dreams. These countries have their own unique appeal.New ZealandSmall though it may be, New Zealand offers quality higher education opportunities, with about 55 percent of its higher education institutes within the top 500 of QS World University Rankings 2019.The highlight of New Zealand’s universities is their ability to provide a high end and student -tailored education for pupils. Though it attracts mainly wealthy students, higher education in New Zealand is also affordable for many common Chinese families. It is where you get a British -based education with the tuition being some of the lowest in the world.ItalyHeart of the Roman Empire and birthplace of the Renaissance, Italy is attractive to Chinese studentsfor its artistic and historic marvels.Similar to Germany, where publicly funded universities offer free undergraduate education, some publicly funded Italian universities offer tuition -free education for international students depending on the level of degree desired. Italy is the 4th most popular study abroad destination in Europe. Each year, over 4,000 Chinese students further their studies at publicly funded Italian universities.CanadaThough Chinese students form the largest international student group in Canada, the country only ranks 4th on Chinese students’ most desirable overseas destinations list.However, the situation may begin to change as Canada and China agreed on new visa policy in early March. Under the policy travel visas are issued with lengths of up to 10 years, which benefits Chinese parents whose children are studying in Canada. Another advantage of studying in Canada, according to an official in the Canadian Embassy to China, is that students can get a three -year working visa right after graduation.21. What is the best part of New Zealand universities? A. They offer British -based education. B. They are the best universities in the world.C. They provide the highest quality education opportunities.D. They provide education specially designed for students.22. What do we know about Italian universities? A. They are modeled after Germany in funding.B. They sponsor all foreign students throughout the college time.C. They offer free undergraduate education in some publicly funded universities.D. They make Italy the 4th most popular study abroad destinations in the world. 23. What do the universities in the three countries have in common? A. They relatively don’t need high expenses. B. They offer working visa after graduation. C. They have convenient application process. D. They are famous for historical and artistic reasons. 【答案】21-23 DCA【解析】这是一篇说明文。
2021年徐庄镇中心中学高三英语三模试题及答案
2021年徐庄镇中心中学高三英语三模试题及答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项ABritain's brilliant bridges have aided trade and brought communities together and are always the most exciting part of the journey. These must-see bridges are now tourist attractions in their own right.Clifton Suspension Bridge, BristolDescribed byits legendary engineer Isambard Kingdom Brunel as “my first love, my darling”, in was originally designed for horse-drawn traffic. Now, more than four million vehicles a year cross the 1,352ft-Jong toll (收费) bridge over the Avon Gorge. The £ l toll for every journey pays for its repair. The history of the bridge, dating back to 1864, is kept alive through a programme of tours, events and exhibitions.Infinity Bridge, Stockton-On-TeesA pedestrian and cycle footbridge across the River Tees, its working title was the North Shore Footbridge, before it was given its grander name when opened in 2009. It is particularly spectacular (壮观) at night. The arches of the bridge are also lit white and, on calm nights, their reflection in the water appears as an infinity symbol, thereby inspiring the name which was chosen by the public.Tower Bridge, LondonAn engineering wonder built from thousands of tons of Cornish granite, Portland stone and steel, it took construction workers eight years to complete. More than 120 years old, it's a popular tourist attraction, as well as a functional bridge. Visitors can take in the views over the capital and experience seeing London life through the Glass Floor.Iron Bridge, ShropshireOpened in 1781, this is the first arch bridge in the world to be made out of cast iron. Recognised as one of the great symbols of the industrial revolution, it transformed the cart of bridge building and was a crucial factor in the development of the iron trade in Shropshire.1.Which bridge has the longest history?A.Clifton Suspension Bridge.B.Infinity Bridge.C.Tower Bridge.D.Iron Bridge.2.What can we know about Infinity Bridge?A.People can just walk on it.B.The public give it two names.C.It's well worth visiting at night.D.It's arch is the biggest on the earth.3.What do Clifton Suspension Bridge and Tower Bridge have in common?A.They are both over 120 years old.B.Visitors should pay for passing them.C.They have the same original design.D.Visitors can have a good view of London on them.BFor 30 years we have been told how temperatures have been rising rapidly to unheard of levels. This is causing polar ice to melt, sea-levels to rise and has brought about adangerous increase in extreme weather events. These intense climatic changes would likely present challenges to our society and environment.The causes of climate change are mainly anthropogenic (人为的) in nature. Since the industrial revolution, human activities have increased the amount of greenhouse gases in the atmosphere. The increased amount of gases which absorb heat has led to more heat being kept in the atmosphere, causing global warming.The certainty of global warming can be seen through some of the natural phenomena like the effect on crops and extreme weather conditions around the world. The most recent assessment report says that the earth’s average temperature has risen by 0. 74 degrees in the period from 1906 to 2005, and that the average temperature will continue to rise. There have also been more violent downpours, sea levels have risen and the ice at the world’s poles and on its mountains is melting. The rising sea level is flooding the low-lying countries inAsiaand small islands in the Pacific. This may lead to the displacement of millions of people, loss of millions of land and consequently billions of dollars.Troubled by the serious situation, world leaders came together for the 2015 United Nations (UN) Climate Change Conference inParis. The climate talks led to 196 countries reaching a landmark agreement that will, for the first time, commit nearly every country to lowering planet-warming greenhouse gas emissions to address global climate change. That was certainly an encouraging step forward for our earth and mankind!As the world leaders continue to commit themselves to monitor our sick planet, we need to continue to take small steps to heal the world. We are left with not much of a choice. If only we could just pack our bags and migrate to Mars!4. What does paragraph 2 mainly talk about?A. The information of industrial revolution.B. The greenhouse gases in the atmosphere.C. The reasons of climate change.D. The result of extreme weather events.5. What can we infer from the last paragraph?A. We have made great achievements.B. Some measures are still required to take.C. Mars is suitable for people’s living.D. Some countries will receive urgent aid.6. Which can be a suitable title for the text?A. Long Live Planet Earth!B.Environment Changes Rapidly!C. What Serious Global Warming!D. How Important the UN Agreement Is!7. Which of the following shows the structure of the whole text?A. B.C. D.CAbout 12 years ago, Sandy Cambron noticed her mother, Pearl Walker, had become quiet after she moved into a nursing home for patients of Alzheimer's disease inKentucky.“We tried everything — photos, old stories — but nothing worked,” she said. “It was really hard for everyone to see how she had changed.” Then one day whileSandywas in a toy store, she had an idea: Why not givePearla baby doll so she could feel as if she were caring for something again? And why not give one to all the other care center seniors?As soon asSandygavePearlthe doll, her mother's face lit up. “She started talking again and she never went anywhere without that baby,”Sandysaid. “She took 'baby' to the dining room with her and slept with her in her arms every night. When she passed away a year later, we even buried her with that well-loved baby doll.”In the following 10 years, Sandy and her husband, Wayne Cambron, continued to buy dolls and hand them out to the elderly of care centers near their home every New Year. Now Pearl's Memory Babies is anonprofit (非营利) organization that has contributed more than 300 dolls to old people with Alzheimer's disease at nursinghomes since February 2018.Last year,Sandyposted New Year’s photos on Facebook, all of which are about seniors reacting to dolls thatshe and Wayne sent to a local nursing home. The post was shared more than 210,000 times overnight. People gave almost $15,000 online. That helped the group buy many dolls.“The dolls offer treatment and comfort,” said Elise Hinchman, who works at a care center inKentucky, "Some seniors cry when they get a doll. And they always rock and talk to their dolls. People with Alzheimer might lose their memories, but they don't lose their ability to love.”8. How did Pearl change after she moved to a nursing home?A. She hardly talked.B. She lost hope in life.C. She felt bored.D. She forgot everything.9. How didPearlreact after receiving the doll?A. She began to cry.B. She was very delighted.C. She played it with a baby.D. She was unconcerned about it.10. What's paragraph 5 mainly about?A. What Sandy did for her mother.B. People's reaction toSandy's post.C. The rising needs for baby dolls.D. HowSandybecame a celebrity.11. What can be a suitable title for the text?A. Good News for Alzheimer's PatientsB. How to Remove Alzheimer's DiseaseC. Baby Dolls Cheer up Alzheimer's PatientsD. Daughter Helps Mother Recover MemoryDAt 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.”12. 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.13. The second paragraph in this passage is mainly about?A. To explain how a robot works.B. To define what a robot is.C. To describe the functions of modern robots.D. To predict the future uses of robots.14. 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.15. 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 together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。

And climate change may be speeding up its loss. Newresearch reports that ancient rock art in Indonesian caves is degrading over time, as bits of rock slowly break off from the walls. It's a huge loss for human history.Salt crystals(结晶)building up on the walls are a key part of the problem, the study suggests. These salt crystals go into the cave walls, changing sizes as temperatures rise and fall. This process causes the rock to slowly break down.Salt crystals may become larger when exposed to repeated changes between wet conditions and periods of drought. These kinds of changes are expected to become more obvious as the climate continues to warm.In particular, the researchers say, climate change may cause more intense El Nino(厄尔尼诺)events in thefuture. These events can strengthen the kinds of conditions that help salt crystals form Scientists are still debating the exact influence of climate change on El Nino, a natural climate cycle that drives changing patterns of warming and cooling in thePacific Ocean.The new study, led by Jillian Huntley, examined 11 ancient cave art sites in South Sulawesi, Indonesia. The researchers found evidence of salt formation at all 11 sites. It's merely a small part There are more than 300 known eave art sites around the region. The researchers note that salt crystals may indeed be part of the problem, adding that climate change is a growing threat, one that deserves more attention.4. What is the main cause of the rocks breaking off from the wall?A. Weather patterns.B. Salt crystals.C. Wet conditions.D. Drought Periods.5. Which of the following may researchers agree with?A. El Nino events prevent salt crystals forming.B. Climate change makes little difference to El Nino.C.Salt crystals may become much larger in wet conditions.D. Constant warm weather may cause salt crystals to change size.6. Which word best describes Huntley's attitude to climate change?A. Worried.B. Curious.C. Doubtful.D. Positive.7. What can we learn from thelast paragraph?A. The formation and patterns of salt crystals.B. The impact of climate change on ancient rock arts.C. The historical value of ancient rock art in cave sites.D. The threats of human activities to ancient eave art sites.CScientists at the Massachusetts Institute of Technology (麻省理工学院) have turned spider webs into music——creating an strange soundtrack that could help them better understand how the spiders output their complex creations and even how they communicate.The MIT team worked with Berlin-based artist Tomas Saraceno to take 2D (two-dimensional) laser (激光) scans of a spider web, which were linked together and made into a mathematical model that could recreate the web in 3Din VR (virtual reality). They also worked with MIT’s music department to create the virtual instrument.“Even though the web looks really random (随机),there actually are a lot of inside structures and you canvisualize (可视化) them and you can look at them, but it’s really hard to grasp for the human imagination or human brain to understand all these structural details,” said MIT engineering professor Markus Buehler, who presented the work on Monday at a virtual meeting of the American Chemical Society.Listening to the music while moving through the VR spider web lets you see and hear these structural changes and gives a better idea of how spiders see the world, he told CNN. “Spiders use vibrations (振动) as a way to locate themselves, to communicate with other spiders and so the idea of thinking really like a spider would experience the world was something that was very important to us as spider material scientists,” Buehler said.Spiders are able to build their webs without shelves or supports, so having a better idea of how they work could lead to the development of advanced new 3D printing techniques. “The reason why I did that is I wanted to be able to get information really from the spider world, which is very weird and mysterious,” Buehler explained. In addition to the scientific value, Buehler said the webs are musically interesting and that you can hear the sounds the spider creates during construction. “It’s unusual and eerie and scary, but finally beautiful.” he described.8. What have MIT scientists done according to the passage?A. They have translated spider webs into sounds.B. They have made a mathematical model to produce webs.C. They have created a soundtrack to catch spiders.D. They have known how spiders communicate.9. What can we know about spider webs from paragraph 3?A. Their structures are beautiful and clear.B. Professor Markus Buehler knows them well.C. The American Chemical Society presents the result.D. They are complex for people to figure it out.10. In which field will the study be helpful?A. virtual realityB. printingC. paintingD. film-making11. What is the main idea of the passage?A. It tells us that the music created by spiders is scary.B. It shows how the researchers carry out the experiment.C. It presents a new and creative way to study spiders.D. It explains why scientists did the experiment.DSince I was born and brought up in a rural town, I have a great interest in nature. Using the chance of studying abroad in my second year at college, I decided to go toCanadajust because I wanted to see the beautiful phenomena there So after I finished the study program, I went toYellowknifein theNorthwest Territories.I clearly remember the sixth night inYellowknife. Suddenly my host mother came to my room around 8 p.m. and told me to change clothes and go outside quickly carrying her camera.The northern lights were flickering (闪烁) in the sky! I was shocked and just stood there with my mouth open.I forgot to take pictures of the mysterious lights.Since that night, whenever it was sunny, I went outside at night and looked at the sky. It was so cold that I lost all feeling in myhands and feet.As I took pictures of the northern lights, I came to find a characteristic movement of the lights. They first appear in the north part of the sky and then they gradually come down to the south part of the sky. After that, suddenly, they come in the middle of the north and south only for a while, which is the time when the best northern lights can be seen. Since it is only a few seconds for the northern lights to come down to the middle of the sky, it is very hard to get good pictures.The stronger the sun acts, the better and stronger the northern lights flicker in the sky. That’s because they come about from the collisions (碰撞) between atmospheric gases and the solar wind. Much more solar wind comes to the earth when the sun is active, whichleads to the best northern lights. And the color1 s of the northern lights depend on the height of the collisions and the kinds of gases.12. Why did the host mother ask the author to go out?A. She wanted to take a picture of him.B. She wanted to take a walk with him.C. She wanted to tell him something important.D. She wanted him to see the northern lights.13. The author forgot to take pictures after going out because ______.A. the host mother didn’t remind him to take the cameraB. he was shocked by the wonderful sightC. the lights flickering in the sky disappeared too soonD. he lost all feeling in his hands and feet14. When is the best time to see the northern lights?A. When they appear in the north part of the sky.B. When they come down to the south part of the sky.C. When they are between the north and south.D. When they rise in the east part of the sky.15. What does the last paragraph mainly tell us?A. Waysto take good pictures.B. The relationship between the sun and the northern lights.C.The color1 s of the northern lights.D. The time of the best northern lights.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 new program, called Chinese Barbecue, tells the story of this popular food cooked over hot coals on just about every street corner in cities and towns across the country. Barbecued meat is an important part of people’s nightlife.Shown on June 20, the program has had more than 25 million clicks on the video site . To find the most popular barbecue stalls (摊位), the production team travelled to more than 500 locations in 30 cities across the country. Some viewers compare Chinese Barbecue to Midnight Diner, a Japanese TV program telling stories from late night informal Japanese bars.“I’m happy to hear this comparison because Midnight Diner is a good program, and we share the same topic― night food,” Chinese Barbecue’s director Chen Yingjie said. “However, they are quite different.” He said that Midnight Diner focused more on food itself, though there was someconversation while people were eating. However, the night food scene of Chinese people means joy and a more lively atmosphere. People eating these barbecue snacks develop a feeling of connection, which can be a cure for loneliness.The barbecue, regarded as the most ordinary and common night street snack, is different from home-made food by mothers as that is a symbol of family and kinship. The barbecue is where you go to become connected to people in society. And unlike official business lunches, during which people are rather polite, the barbecue lets people relax with old friends and new friends, leaving a lasting impression of friendship.The world, as a whole, holds deep-rooted good feelings toward the barbecue, either for the taste or the warmth produced by fire. “What we should do is to present the Chinese barbecue just the way it is because withits special ingredients(食材),ways of cooking and more importantly, the special environment and people, the world will recognize it and might fall in love with it just as we do.” said Chen.4. What do we know about Chinese Barbecue?A. It has been becoming very popular on the Internet.B. It is thought highly of by most of the foreign tourists.C.

Every day, the chimpanzees at Project Chimps receive morning and evening food-based enrichment devices, but caregivers are always looking for more ways to keep the chimps mentally engaged. With 79 chimpanzees, each with their distinctive personality, care staff often find that different chimps react differently to new enrichment.Last year, we began inviting musicians to perform for chimps to see what they may respond. A violin performance received quite the response. Additional musicians were lined up to visit but the coronavirus has stopped the activities, which we hope toresumein the near future.This past week, we brought an electric piano for the chimps to investigate. Some chimps, like twins Buttercup and Clarisse, were immediately interested and could not wait to tap out a few notes. Others, like Emma, were more interested in trying to take it apart.29- year-old Precious has very little tolerance for the piano. She sat off to the side for a few minutes, but eventually she decided that was enough. She called an end to the enrichment session by throwing a handful of waste at the piano. Receiving her message loud and clear, we removed the piano.We could never have guessed how 33-year-old Luke would react to it. As with many retired lab chimpanzees Luke has some anxiety issues. He seems particularly distrustful of anything new, including people, food, and enrichment. But when we presented the chimps with the piano, Luke was the first to investigate. We could not believe our eyes — this usually anxious chimpanzee bravely chose to explore something new!To us at Project Chimps, this is what it is all about: giving chimpanzees the freedom to choose. We are honored to be part of their journey.8. Why do chimpanzees respond differently to new enrichment?A. They are of different genders.B. They have natural curiosities.C They are as intelligent as humans. D. They have their unique characters.9. What does the underlined word “resume” in Paragraph 2 mean?A. Continue.B. Suspend.C. Monitor.D. Regulate.10. Who showed the least interest in the piano?A. Buttercup and Clarisse.B. Emma.C. Precious.D. Luke.11. What is the text mainly about?A. How caregivers care for the retired chimpanzees.B. What care staff do to enrich chimpanzees' daily life.C. How chimpanzees are trained through various enrichment.D. What Project Chimps does to observe and study wild chimps.DIn order to develop the pandemic-stricken economy, China recovered the street vendors(商贩)in a new nation-wide method known as “street stall economy'', allowing residents to set up open-air shops on the sidewalks or other available public spaces.Street vendors were once an important part ofChina's economy and urban landscape. 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 sales of local produce. In attempts to promote various live streaming platforms, many tech CEOs also made their own live streamed e-commerce debuts(首次亮相)selling goods coming from all over the country.12. What does the underlined part “dish out" in Paragraph 3 mean?A. turn down.B. provide with.C. pay off.D. apply for.13. Compared with and Tencent, what unique measure did Ant Financial take?A. It provides interest-free loans for vendors.B. It offers interest-free credit line to customers.C. It provides quality goods for street vendors.D. It offers marketing support to businessmen.14. What's the purpose of the cooperation between WeChat andGuangzhoucity?A. To volunteer to train street vendors.B. To give away free goods to the poor.C. To promote to develop the local economy.D. To help CEOs make their own streaming platforms.15. What can be the best title for the text?A. Chengdu and Yantai Succeeded in Creating Job OpportunitiesB. "Street Vendor Economy” Greatly Increases People's IncomeC.

Raymond Brown has worked at the school as a guard for the past 15 years. All of the students know and love him, and he's truly a friend to all. He started callingAdrian's son “Famous Amos” on day one. To the mom's surprise, Amos quickly began responding with a cheerful "Hey, Brown” whenever he saw him. "He wasn't even saying 'daddy' at home, so it was really something, "Adriansaid.“Amos is a hard friend to have,"Adrianexplained, "He takes a lot more than he gives and that's tough for children. But those kids saw that he was popular and loved, and they started fighting over who would get to hold Amos' hand on the way to the classroom. It meant so much to me that he was favored by the other children at school, and Mr. Brown had a big hand in that.”About a year ago, school officials nominated Mr. Brown forNorth Carolina's School Hero, a $20,000 prize. When the results came out and he didn't win,Adrianwas heartbroken.

She connected them in rows, and by the end she designed the item into a skirt and wore it.She said that the idea behind her unique clothing item came out of a desire to normalize rejection and take pride in overcoming it. "The whole process of revisiting those old letters and making that skirt sort of reminded me that you have to apply to a lot of things to succeed," she said. "A natural part of the process is to get rejected along the way."Caitlin's adviser, Julie Libarkin, a professor of earth and environmental science atMichiganStateUniversity, also encourages the acceptance of failure in her students. Libarkin believes it's important for students to get into habit of applying for things, and to get used to the feeling of rejection, so she encourages them to chase after any opportunity that comes their way. If a student doesn't get the grant or the spot in the academic journal, that's okay. They'll still have learned something in the process.As for Caitlin? Her rejections over the years have led to great things: Since her doctorate, she's won a scholarship to do further research on urban agriculture inGermany.Currently, she's a post-doctoral researcher at the University of Nebraska-Lincoln. As for what the future holds? "I'm prepared to receive a few more rejection letters along the way," she joked heartily, "Maybe I'll make a longer skirt."4. What can we learn about Caitlin Kirby's rejection letters?A. She received 17 rejections in total.B. 29 of her rejections were from journals.C. The rejections were connected into a fan.D. She made some rejection letters into a skirt.5. What is Julie Libarkin's attitude towards Caitlin's action?A. Favorable.B. Ambiguous.C. Skeptical.D. Opposed.6. Which of the following words can best describe Catlin?A. Creative and considerate.B. Caring and determined.C. Optimistic and humorous.D. Generous and intelligent.7. Which of the following may Caitlin agree with?A. Hard work pays off.B. Education is the entrance to success.C. Self-respect earns more respect.D. One needs to normalize failures.CA male tiger was rescued in Mishan city, Northeast China's Heilongjiang province, on Friday. A tiger was recently seen on the Siner Russian border(边界),but there is no evidence to suggest this is the same tiger or that it had lost its way from Russia.Wherever it may have come from, cross-border protection of endangered species is a problem. According to Ma Jianzhang, a senior wild animal researcher in China, tigers know no borders, which have been built to stop humans from illegally crossing over. However, these borders also stop the free movement of tigers, thus preventing their breeding(繁殖)and exchange of genes.The Sino-Russian border alsocomes in the way ofprotecting tigers in the region. Data show about 500 to 550 Siberian tigers, or over 90 percent of the species, live in the wild in Russia; 27 live in the wild in China, and 50 inthe border region. Sometimes tigers lose their way across the border and that is hindering(妨碍)efforts to stop illegal hunting and protecting them.Fortunately, both China and Russia have realized this problem and are working toward solving it. As early as 2010, the two countries established a cross-border protection network aimed at strengthening communication on protecting tigers in the northeast. The countries have also held anti-poaching(反偷猎)activities together. In 2019,two national parks from the two countries signed a three-year deal to share research data on tigers, greatly improving the living conditions of Siberian tigers in the wild.However, much more needs to be done to protect the species. It is necessary to combine the tiger protection areas in the two countries. That will require greater efforts from both sides and some difficulties might remain even then. Fortunately, both countries have been taking effective measures to provide the endangered species a better home.8. What's the original purpose of setting up the Sino-Russian borders?A. To ban people from illegal crossings.B. To help protect tigers in the region.C. To protect tigers from losing their way.D. To stop tigers' breeding and exchange of genes.9. What does the underlined phrase “comes in the way of” probably mean?A. keeps from.B. is on the way toC. is aimed atD. keeps up10. What is the focus of Paragraph 4 ?A. Recent studies and researches on tigers.B. Joint efforts by China and Russia to protect tigers.C. The possible effects of establishing a networkD. Reasons for improving the living conditions of tigers.11. What's the author's purpose in writing the text?A. To inform the possible dangers of tiger protection.B. To cover the news about a missing tiger on the border.C. To put forward suggestions on finding the missing tiger.D. To report the problems and measures of cross-border tiger protection.DA smiling panda and a walking Chinese lantern will be the mascots of the 2022 Winter Olympics and Paralympics (残奥会)in Beijing .The mascots were known to the public on Sept.17, 2019 at a ceremony inBeijing. Beijing Mayor Chen Jining described them as adorable, unique , and exquisite (精致的)。
2021届北京市154中学高三英语第三次联考试题及答案解析
2021届北京市154中学高三英语第三次联考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AIt's just before l pm and hungry guests are starting to emerge out onto the wooden floor at the back of the Victoria Falls Safari Lodge in Zimbabwe. A few have already settled in for lunch, drinking beer and enjoying their sandwiches and salads in the sunshine. It's a normal setting until you look up. Overhead, the sky is filled with several hundred vultures (秃鹭).They too have arrived for their midday snack. Every day the team at this hotel places last night's leftover meat out for the vultures to eat. They call it the "Vulture Restaurant" and it's a vital part of protecting these birds, who have become some of the most endangered species in Africa.In Zimbabwe, where illegal hunting of elephants and rhinos is a major issue, poisoning poses a significant threat to the birds. "In recent years hunters have realized they can use poison to kill animals. It's effective because it's silent and therefore doesn't attract much attention.when the vultures eat the bodies of the dead animals they die too," says Roger Parry, Wildlife Manager at the Victoria Falls Wildlife Trust.The Vulture Restaurant initiative is part feeding programme, part education programme. By attracting the birds to the Vulture Restaurant every day the team can ensure they're regularly getting a safe meal, and while the birds are there they can educate tourists from all over the world about these creatures.“Lunch” is served by Moses Garira. He has the unenviable task of wandering out into the middle of the clearing with a box full of meat, dropping the contents onto the ground and running for his life as the vultures fly downward suddenly for their food. No one, surely, would volunteer for this role, but Garira rather enjoys it. Back in the safety of the viewing seats, he tells the onlookers about the importance of vultures. "They're hugely important in terms of their role of cleaning up the bodies of dead animals," says Garira. "Notably, they're safely able to digest bacteria like anthrax. Without vultures, there'd be a lot more disease in the world."1. What's the biggest threat vultures facing in Zimbabwe?A. Overhunting.B. Unsafe food.C. Loss of habitat.D. A bird disease.2. What would others think of Garira's job?A. Scary.B. Relaxing.C. Well-paid.D. Time-consuming3. What do Garira's words mean?A. Birds are human's best friends.B. People know little about vultures.C. Vultures are environmentally favorable.D. Vultures are in urgentneed of protection.BWhen my friend suggested going to the op shop (二手商店),instantly I thought “I hope no one I know sees me”. It was the same when my cousin commented on my new furniture and Japanese, fine-bone-china bowls and asked where I got them. They were from the local op shop but instead I said “from the antique shop”.Many people in my Greek-Cypriot community would look down on me if I said I shopped at the op shop. They may pity me, consider me poor, a failure. Immigrants sacrificed their families and homes for a better life. Buying a house and having enough money to live comfortably, to educate your children and see them also live comfortably, are a big part of the immigrant dream, But has this dream made us materialistic at the cost of our own planet?Our love for purchasing the latest trendy clothes or furniture, then donating them when we are tired of them has become normal. I was once like this. But after watching the documentaryThe True CostI learned donated clothes that don’t get sold are sent to developing nations, many of them ending up in landfills (垃圾填埋地). In addition, your new dress requires electricity and materials to make. But if you buy a second-hand dress, that’s one less dress in a landfill and one less new dress to be made.A friend introduced me to op shopping only a few years ago. My firstitem was a dress she gifted me. It was lovely and I loved it. Nobody could tell it was second-hand. This opened me up to purchasing more second-hand high quality branded clothes. Once I visited a friend and was impressed by how she decorated her apartment. “It’s all second-hand,” she said. I couldn’t believe it. The truth is a lot of things sold at the op shop are in new or almost new condition. That’s when I made the decision to only buy second-hand things.Selling second-hand things isn’t anything new butwhat the planet needs is more buyers. There is so much excess (过量) production in the world. So stop feeling ashamed, and let’s get shopping.4. What kind of feeling is expressed in Paragraph 1?A. Pride.B. Embarrassment.C. Delight.D. Sympathy.5. Whatare many people in the author’s community like?A. They are probably materialistic.B. They care about the environment.C. They think highly of op shopping.D. They look down upon immigrants.6. What was the author encouraged to do after visiting her friend’s apartment?A. Watch the documentaryThe True Cost.B. Donate more to local charities.C. Avoid shopping too much.D. Stop buying new things.7. What’s the purpose of the text?A. To entertain.B. To advertise.C. To persuade.D. To describe.CThe English language is changing, and you are responsible! Whether we consider changes in grammar, spelling, pronunciation, or the very vocabulary of the language, you have played your part and continue to do so.When we first learned basic grammar and spelling, perhaps in elementary school, we might have gotten the impression that these things were sacred. The rules that apply to such things might have been presented as unchanging and unchangeable. While this way might be helpful for teaching children, it is far from accurate.The English language, like many others, is a living, growing, ever-evolving thing. Like it or not, you are involved in this change. These changes take many forms. Grammar and spelling have changed greatly over the years and centuries, with the spelling differences in different countries today a reflection of this. While the language of a thousand years ago might be called English, most of us would hardly recognize it today as the same language.The first involves changes in the pronunciation of words. Many are familiar with the differences between the British and American ways of pronouncing certain words. In addition to these differences, the pronunciation of many words has changed over the years because of how you have decided to pronounce them. For example, consider the word "err." The traditional pronunciation of this word rhymes with the word "her." Older dictionaries show this to be the primary or only pronunciation. However, in recent years, more and more people have beenpronouncing it so that it sounds like "air." Another change in the language involves the addition and removal of words. The makers of dictionaries decide which words deserve to be officially adopted as part of the English language. Through the centuries, many words have come from other languages. In fact, English has probably done this more than any other language in the world, which is why spelling and pronunciation rules for English have so many exceptions.Of course, many slang words have been just short-lived fashions that have died out quickly. Others, though, have been adopted by mainstream society and become respectable, as have many technical terms. So then remember, the next time you repeat the newest expression to hit the street, or make up your own words, you may be contributing to the future of the English language.8. When we begin to learn English, we think _________.A. it is interesting to pick up a new languageB. English rules are wrongly presented in factC. grammar and spelling rules are unchangeableD. only adults have the ability to affect a language9. From paragraph 3 we can know that_________.A. we can change the English languageB. many languages are changing over yearsC. English has changed little in the past 1,000 yearsD. there were main changes in grammar and pronunciation10. Why is the pronunciation of words changing?A. people speak in different waysB. people have adopted foreign wordsC. it has been affected by American EnglishD. makers of dictionaries often change them11. Which of the following is the best title for the passage?A. Foreign words involved in English.B. The British speaks differently from Americans.C. English language is changing over years.D. You can change the English language.DAdvertisers tend to think big and perhaps this is why they're always coming in for criticism. Their critics(批评家)seem to hate them because they have so much money to throw around. Why don’t they stop advertising and reduce the price of their goods? After all, it’s the consumer who pays.The poor old consumer! He'd have to pay a great deal more if advertising didn't create mass markets for products. It is precisely because of the heavy advertising that consumer goods are so cheap. But we get the wrong idea if we think the only purpose of advertising is to sell goods. Another equally important function is to inform. Agreat deal of the knowledge we have about household goods is largely from the advertisements we read. Advertisements introduce us to new products or remind us of the existence of ones we already know about. Supposing you wanted to buy a washing machine, it is more than likely you would obtain details regarding performance, price, etc., from an advertisement.Lots of people pretend that they never read advertisements, but this claim may be seriously doubted. It is hardly possible not to read advertisements these days. And what fun they often are, too! Just think what a railway station or a newspaper would be like without advertisements. Would you enjoy gazing at a blank wall or reading railway byelaws while waiting for a train? A cheerful, witty advertisement makes such a difference to a dull wall or a newspaper full of the incidents and disasters.We must not forget, either, that advertising makes a positive contribution to our pockets. The fact that we pay so little for our daily paper, or can enjoy so many broadcast programmers is due entirely to the money spent by advertisers. Just think what a newspaper would cost if we had to pay its full price!Another thing we mustn't forget is the “small ads.” What a tremendously useful service they perform for the community! Just about anything can be accomplished through these columns. For instance, you can find a job, buy or sell a house, announce a birth, marriage or death in what used to be called the “hatch, match and dispatch” column(栏目) but by far the most fascinating section is the personal or “agony” column. No other item in a newspaper provides such entertaining reading or offers such a deep insight into human nature. It's the best advertisement for advertising there is!12. What is the main idea of this passage?A. Advertisements steal money from our pocketsB. The critics get the wrong idea of advertisements.C. Advertisers perform a useful service to communities.D. Advertisements are everywhere.13. What is the attitude of the author toward advertisements?A. He appreciates the role of advertisements.B. He doubts the effect of advertisements.C. He believes what is said in advertisements.D. He complains too many advertisements in daily life.14. Which of the following is Not True?A. The personal or “agony” column makes us know more about human nature.B. The only purpose of advertising is to sell goods.C. A newspaper will cost us more if there is no advertisement on it.D. Advertisement makes our life color1 ful.15. Whicof the following shows the structure of the passage?( ①=" Paragraph" 1, ②=" paragraph" 2, ③=" paragraph" 3, ④=" paragraph" 4 ⑤=" paragraph" 5)A B.C.

2021年北京市154中学高三英语第三次联考试卷及答案解析
2021年北京市154中学高三英语第三次联考试卷及答案解析第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AYou have to praise the smoothness(顺畅)of ants on the move. No matter how many of them are going toward a place, there's never a hold-up. A new research paper shows how ants keep traffic flowing by changing their behavior to meet changing conditions.For their experiments, researchers from the University of Toulouse focused on Argentine ants, animals that often move from colony(群落)to colony depending on where the food is. Making use of Argentine ants' talent for fast travel, the researchers built bridges connecting their colonies. The bridges were different in width from a fifth to three-quarters of an inch. The colonies, too, were of different sizes, ranging from 400 to more than 25,000 ants.Then the researchers sat back andmonitoredthe traffic. To their surprise, even when those narrower bridges were full of ants, there were no "traffic accidents". "When the number of ants on the bridge increased, ants seemed to be able to understand the situation and adjusted(调整)their speed accordingly to avoid making the traffic flow stop. "the authors note. "Moreover, ants avoided entering a busy road and made sure that the bridge was never too packed to cross.”The lesson for humans? The traffic problem may lie in our inability to adjust our driving habits for the good of the whole. Driving is fun when there are few cars on the road. Then the traffic moves very slowly. And yet, some impatient driver still acts like he's alone on the road.The research suggests that projects, like the ever-widening of highways, may never free us from traffic jams. As long as we drive along with our own habits, no matter how many other people are on the road, we'll always end up in a traffic jam. Indeed, less space may actually be a good thing. It leaves less room for individual choice and forces us to take a page from the driving book of ants.1. What is Paragraph 2 mainly about?A. The results of the experiments.B. The purpose of the experimentsC. The preparation of the experiments.D. The requirements of the experiments2. What does the underlined word "monitor" in paragraph 3 probably mean?A. watch and check.B. seek and improveC. design and planD. discuss and practise3. What is the best title for the text?A. Is widening highways a solution?B. Why don't ants need traffic lights?C. Can we learn safe driving from ants?D. What can ants teach us about traffic jams?BThe 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.4. 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.5. 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 problems6. 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 saltwater7. 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.CMost children who have suffered from ADHD still have it as teens. During teen years, especially as the hormonal changes of teenagers are going on and the demands of school and extra-curricular activities are increasing, ADHD may get worse.Because of problems with getting unfocused and poor concentration, many teens with ADHD have problems in school. Grades may fall, especially if the teen is not getting ADHD treatment. It’s not uncommon for teens with ADHD to forget their homework, lose textbooks, and become bored with their daily class work. Teens may become inattentive or extremely attentive, not waiting for their turn before blurting out answers. They may cut in on their teacher and classmates. Teens with ADHD may also befidgetyand find it hard to sit still in class.Often, teens with ADHD are so busy focusing on other things that they forget about the task at hand. This can be seen especially with homework and athletic skills and in relationships with their schoolmates. This lack of attention to what they’re doing often leads to bad grades on tests and being passed over for sports teams, after-school activities, and learning teams. Kids with ADHD can be targets for bullying, too. But, not all children with ADHD have trouble getting along with others. If your child does, you can take measures to help improve their social skills and relationships.ADHD affects all parts of a teenager’s life. As a parent you should discover your teen’s troubles as early as possible. The earlier your child’s troubles are discovered, the more successful the following steps can be.8. What does the author plan to do in paragraph 1?A. To list the types of ADHD.B. To introduce the main topic.C. To show the author’s opinion.D. To explain the causes of ADHD.9. What does the underlined word “fidgety” probably mean in paragraph 2?A. Clever.B. Noisy.C. Restless.D. Lazy.10. What is the text mainly about?A. Ways to deal with ADHD.B. Effects of ADHD on teens.C. Teens’ school performances.D. Demands of school work.11. What may the following paragraph talk about?A. How parents can help a teen with ADHD.B. The importance of healthy peer relationships.C. How many children are suffering from ADHD. D. Different opinions about treating ADHD in teens.DAs 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.

They are expensive but of practical use.D. They are being used by people.BWhy isn’t science better? Look at career incentive(激励).There are oftensubstantial gaps between the idealized and actual versions of those people whose work involves providing a social good. Government officials are supposed to work for their constituents. Journalists are supposed to provide unbiased reporting and penetrating analysis. And scientists are supposed to relentlessly probe the fabric of reality with the most rigorous and skeptical of methods.All too often, however, what should be just isn’t so. In a number of scientific fields, published findings turn out not toreplicate(复制), or to have smaller effects than, what was initially claimed. Plenty of science does replicate — meaning the experiments turn out the same way when you repeat them -but the amount that doesn’t is too much for comfort.But there are also waysin which scientists increase their chances of getting it wrong. Running studies with small samples, mining data for correlations and forming hypotheses to fit an experiment’s results after the fact are just some of the ways to increase the number of false discoveries.It’s not like we don't know how to do better. Scientists who study scientific methods have known about feasible remedies for decades. Unfortunately, their advice often falls ondeaf ears.Why? Why aren't scientific methods better than they are? In a word: incentives. But perhaps not in the way you think.In the 1970s, psychologists and economists began to point out the danger in relying on quantitative measures for social decision-making. For example, when public schools are evaluated by students’ performance on standardized tests, teachers respond by teaching “to the test”. In turn, the test serves largely as of how well the school can prepare students for the test.We can see this principle—often summarized as “when a measure becomes a target, it ceases to be a good measure”—playing out in the realm of research. Science is a competitive enterprise. There are far more credentialed (授以证书的) scholars and researchers than there are university professorships or comparably prestigious research positions. Once someone acquires a research position, there is additional competition fortenure grant funding, and support and placement for graduate students. Due to this competition for resources, scientists must be evaluated and compared. How do you tell if someone is a good scientist?An oft-used metric is the number of publications one has in peer-reviewed journals, as well as the status of those journals. Metrics like these make it straightforward to compare researchers whose work may otherwise be quite different. Unfortunately, this also makes these numbers susceptible to exploitation.If scientists are motivated to publish often and in high-impact journals, we might expect them to actively try to game the system. And certainly, some do—as seen in recent high-profile cases of scientific fraud(欺诈). If malicious fraud is the prime concern, then perhaps the solution is simply heightened alertness.However, most scientists are, I believe, genuinely interested in learning about the world, and honest. The problem with incentives is that they can shape cultural norms without any intention on the part of individuals.4. Which of the following is TRUE about the general trend in scientific field?A. Scientists are persistently devoted to exploration of reality.B. The research findings fail to achieve the expected effect.C. Hypotheses are modified to highlight the experiments' results.D. The amount of science that does replicate is comforting.5. What doesdeaf earsin the fourth paragraph probably refer to?A. The public.B. The incentive initiators.C. The peer researchers.D. The high-impact journal editors.6. Which of the following does the author probably agree with?A. Good scientists excel in seeking resources and securing research positions.B. Competition for resources inspires researchers to work in a more skeptical way.C. All the credentialed scholars and researchers will not take up university professorships.D. The number of publication reveals how scientists are bitterly exploited.7. According to the author, what might be a remedy for the fundamental problem in scientific research?A. High-impact journals are encouraged to reform the incentives for publication.B. The peer-review process is supposed to scale up inspection of scientific fraud.C. Researchers are motivated to get actively involved in gaming the current system.D. Career incentives for scientists are expected to consider their personal intention.CScientists have discovered a new behaviour among bumblebees that tricks plants into flowering early.When lack of pollen, bumblebees will bite little by little on the leaves of flower-less plants. The damage seems to fool the plant into flowering, sometimes up to 30 days earlier than normal.With their hairy appearance and special sounds, bumblebees are hard to miss in gardens all over the world. Their hairy bodies make them excellent pollinators for crops like tomatoes and blueberries. They are among the first bees to appear each year and work a long season.But despite their key role, bumblebees, like many other pollinators have seen their numbers decline suddenly in recent decades. One recent study pointed to climate change, reporting that an increasing number of hot days in Europe andNorth Americawas raising local bumblebees extinction rates.But researchers have now made a discovery about bumblebees that could have something to do with their long term survival. Scientists inSwitzerlandfound that when the bumblebees were out of pollen, they started to bite on the leaves of plants that hadn't yet flowered. They used their mouths to cut clearly-shaped holes in the leaves. But the creatures didn't eat the material or use it in their nests.The damaged plants responded by flowering earlier than normal--in some cases up to 30 days ahead of schedule. Researchers also found that the bee damaged plants flowered 30 days earlier than undamaged plants and 25 days earlier than ones damaged by the scientists.“I think everything that we've found is consistent with the idea that the bumblebees are damaging the plants and that that's an adaptation that brings flowers earlier and that benefits the bees,” said Dr Mark Mescher, one of the authors from ETHZurich.8. How do bumblebees fool plants into flowering earlier?A. By making use of the hot weather.B. By putting the false flowers on the leaves.C. By attacking the leaves of flowerless plants.D. By taking away the pollen from the other flowers.9. What's bumblebees’ key role?A.Making plants flower early.B. Spreading pollen to flowers and plants.C. Sending information about weather change.D. Finding out whether the plant has flowers.10. What has happened to bumblebees in the past the years?A. They are becoming homesick.B. They are not as friendly as before.C. There is a sharp decrease in number.D. They have been busy year by year.11. What's Dr Mark Mescher's attitude towards the behaviour of bumblebees?A. Uncaring.B. Skeptical.C. Tolerant.D. Objective.DKids ages 6 to13 inCape Town,South Africa, really do dig learning at school! With the help of the Earthchild Project, which is offered in schools in two townships, students make worm(蠕虫) farms. The worms break down food waste and make the soil richer. Kids grow seedlings(幼苗) in containers and learn about the importance of good nutrition.The school program also offers yoga(瑜伽). Teachers find that the exercises help students focus better. The students enjoy Earthchild activities. “The children gets so excited”, says teacher Vuyelwa Rola.“The society we are in has a lot of noise. When students are taking part in the Earthchild Project, they feel calm.”Director Janna Kretzmar came up with the idea for the project in 2005. She read about schools inIndiathat involved kids in yoga and learning outside the classroom. She developed the Earthchild Project to offer similar activities inCape Townschools.“We hope the Earthchild Project can help students find solutions to all the challenges they are facing in the world today,” Kretzmar said. “The best place to create change is with the youth, through education.”The Earthchild Project combines schoolwork with hiking, gardening, healthy living, and yoga. “We need more than just math and science to become happy, healthy, inspired, and active citizens of our communities,” says Kretzmar. In some communities inCape Town, children live in poverty. They must walk long distances to get clean drinking water. Life is hard. But according to the Earthchild Project’s Carly Appleby, the project works to give hope to every child. “Students who have hope,” she says, “aim for bigger goals”.12. What do students benefit from yoga?A. It helps them calm down.B. It helps them concentrate.C. They can learn some living skills.D. They can learn about the importance of nutrition.13. What are students’ attitude towards the Earthchild Project?A. Uncaring.B. Doubtful.C. Supportive.D. Negative.14. What do you know about the Earthchild Project?A. It was founded in 2005.B. It only offers outside activities.C. The idea came up by Vuyelwa Rola.D. It is aimed at helping students find solutions to challenges.15. What’s the best title of the passage?A. Hard Life inSouth Africa.B. Students’ school life inCape Town.C. Hope from Earthchild Project inCape Town.D. The differences between traditional lessons and Earthchild Project.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。

Lucy’s remains were uncovered in Ethiopia in the 1970s, with the 3.18 million-year-old skeleton(骨骼)being the most complete of any upright, walking human ancestor. Since she was discovered, researchers have debated whether she spent her life in the trees or spent time walking on the plains as well.The new evidence from scans of her arm bones proves she spent time climbing and used her arms to pull herself up. The scans were compared with cross sections of humans and chimpanzees, which spend a mixture of time in trees and walking on all fours on the ground. They found that the arm bones were more heavily built, similar to those of chimps, while her lower limbs(下肢)would have meant she walked less efficiently than modern humans. Professor John Kappelman, atUniversityofTexas, believes the advantage of his study was that it focused on characteristics that reflect actual behavior during life, suggesting that evenwhen Lucy walked upright, she may have done so less efficiently than modern humans, limiting her ability to walk long distances on the ground.Previous studies suggested that Lucy was just 4 feet tall and weighed just 65 pounds. Combining the new data paints a picture of an ancestor who may have spent a great amount of her time in trees. It also expands on evidence from earlier this year which claimed that Lucy may have died from a fall, most likely from a tree. The evidence suggests Lucy may have spent time on the ground, returning to the safety of the trees for food and to sleep, to avoid her enemies.4. What did the researchers argue about after Lucy was discovered?A. Where she lived.B. How long she lived.C. What she ate.D. How she worked.5. How could people tell Lucy spent time climbing?A. By her walking style.B. By her heavily built arm bones.C. By her strong lower limbs.D. By her large cross sections.6. When Lucy walked, she may________.A. have walked with bigger stepsB. have walked at a faster speedC. have walked more efficiently than usD. have walked a shorter distance than us7. What is the main idea of the last paragraph?A. Guesses about Lucy’s characteristics.B. Some evidence of Lucy’s health.C. The safety of Lucy.D. The ancestor of Lucy.CMove over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don’t sleep through a test, and even calling their kids’ employers.Helicopter parenting the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”8. What do we know about snowplow parenting?A. It appeared before helicopter parenting.B. It costs parents less than helicopter parenting.C. It was a typical phenomenon of the 20th century.D. It provides more than enough services for children.9. What is mainly discussed about snowplow parenting in Paragraph 4?A. Its cost.B. Its benefits.C. Its popularity.D. Its ending.10. Why does the author mention parents’ taking away car keys?A. To show teenagers are no better than babies.B. To advise teenagers not to treat their cars as toys.C. To advise parents not to buy cars for their teenagers.D. To show it’s appropriate to help children when necessary.11. What’s the possible result of snowplow parenting according to the experts?A. Children lacking problem-solving ability in reality.B. Children mastering more key life skills than parents.C. Children gaining great success in every aspect of life.D. Children meeting no problems or frustration after growing up.DPhotographer Rebecca Douglas has always been fascinated by the night sky. Her love for stars has taken theU.K.resident on “star walking” trips toIcelandand into theArctic, where she steps out onto darkened trails to capture twinkling stars and glowing planets in her images.Hiking at night isn’t uncommon. Plenty of people hike after dark to get to campsites or watch the sunrise from a mountaintop. Star walking goes a step further by blending hiking with stargazing. Rather than heading to an observatory or setting up a telescope in your backyard,star walking takes you on a brief journey to look at the stars from different viewpoints.Whether you’re in the mountainside or by the lake with stars reflecting on the water, star walking is often much more dynamic than traditional stargazing.What’s more, star walking is good for you. There are plenty of studies that show the health benefits of being in nature. Spending at least two hours a week outdoors, particularly while engaging in what involves “effortless attention”, can decrease blood pressure, heart rate, and stress levels.So how does an aspiring star walker get started? It doesn’t take much more than a sturdy pair of boots.While telescopes and binoculars obviously have their uses, people are encouraged to start with naked-eye stargazing. Using only the eyes allows one to get lost in the infinite expanse of space and lets the mind go.It is advised that one read up on the night sky before heading out. Free mobile apps, such as Star Walk 2, can help identify celestial bodies(天体)and are easy to use—simply point your phone at the sky to reveal a map. Websites like Sky & Telescope and NASA’s Space Place cover the basics, have in-depth explanations on stars, and offer advice on equipment. Space Place posts monthly skywatching updates, so you can plan outings around events such as meteor showers.In the United States, national parks are great options for inexperienced night hikers. Many offer guided outings that explain the importance of protecting night skies. Those with a good number of walks under their belt may want to try GlacierNational Park in Montana.If national parks and other dark-sky designated areas are out of range, check local astronomy clubs and observatories for guided sessions. Sites like the International Astronomical Union are useful for finding resources by area.At the end of the day, the best advice is to take it slow and enjoy the journey.“With all of the chaos(混乱)that’s happening around us, the one constant has been the night sky,” explains Douglas, who hasbeen exploring popular places nearby, long after the crowds have gone home for the day. “Walking is quite a mindful way of looking up and being reminded that, although everything feels so different, some things are still the same.”12. According to the passage, star walking refers to ________.A. going to an observatoryB. looking at stars in mountainsC. combining hiking and stargazingD. setting up a telescope in the backyard13. One of the reasons why people go on a star walking is that _______.A. it’s easier to identify celestial bodiesB. it is good for physical and mental healthC. they can enjoy the journey without crowdsD. they can raise awareness of protecting night skies14. According to the passage, a star walking beginner is advised to _______.A. prepare a pair of strong bootsB. start by observing with telescopesC. join an astronomy club or an observatoryD. find guided outings with the help of mobile apps15. The main purpose of the passage is to ________.A. excite people’s interest in star walkingB. recommend some places for star walkingC. explain the health benefits of star walkingD. introduce the preparations for star walking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。
