第一部分阅读理解(共两节，满分60分)第一节(共15小题；每小题3分，满分45分)AFour of the Oldest Buildings in the WorldKnap of HowarOne of the oldest buildings in the world is the Knap of Howar, which dates back to 3700-3500 BCE. The farmhouse is one of the oldest, still-standing stone houses in Europe. It includes two stone homes linked through a hidden passage and joint walls. Archaeologists say Irish or Scottish monks could be the first builders and residents of the Knap of Howar. Although the house is still standing, these abandoned places around the world are better candidates for restoration.Ggantija TemplesThe Megalithic Temples of Malta, or the Ggantija Temples, date back to 3600 to 3200 BCE. The two temples on the island of Malta are UNESCO World Heritage sites. It’s one of the oldest free-standing monuments in the world. Archaeologists think the temple was used for ritual animal sacrifices.Shunet el-ZebibShunet el-Zebib is partially standing, but mostly in ruins. It’s still, however, one of the oldest buildings in the world. The Egyptian temple built in 2750 BCE is of mud and brick. It has an underground tomb as well as an above-ground complex. Architecturally, it’s a nod to the Egyptian pyramids soon to come.Tomb of CyrusBuilt in 530 BCE, the Tomb of Cyrus is one of Iran’s World Heritage Sites and one of the oldest buildings on the planet. It’s also believed to be one of the first earthquake-protected structures in the world, according to Atlas Obscura. The base isolating used on the tomb protects the main structure from moving apart from the foundation.1. What do the four buildings have in common?A. All of them are located in Europe.B. All of them are made of stone and mud.C. All of them are UNESCO World Heritage Sites.D. All of them were built before the birth of Christ.2. Which of the four buildings may be the strongest?A. Knap of Howar.B. Ggantija Temples.C. Shunet el-Zebib.D. Tomb of Cyrus.3. Which of the following is True according to the passage?A. Shunet el-Zebib is earthquake protected.B. Tomb of Cyrus has an underground tomb.C. Ggantija Temples are built by Irish monks.D. Knap of Howar may be the oldest building among the four.BIn the summer of 2010, Deborah Barrett and her son, Anthony, walked out of a restaurant near the Edmonton high school from which he’d graduated two years earlier. They had volunteered to wash dishes there to give Anthony something to do, but when they went out, the sun sliced through the clouds and Deborah had a realization: my kid is not spending his life in a dish pit.Cleaning plates isn’t the only option for high-school graduates. But Anthony has autism(自闭症)and is mostly non-verbal, aside from short words in answer to yes-or-no questions and the Eeeee sounds he makes when he’s excited, happy or frustrated. Once a person with intellectual disabilities ages out of school, “There’s no life for them,”Deborah says. Programs end, and jobs are usually humble.As her son entered his 20s, Deborah thought about what he could do and what he enjoyed. Among his likes: being driven around and carrying things, as well as seeing new places but not staying long. Maybe he could be a courier? The catch: Anthony doesn’t move fast, and courier jobs would require his support staff to be his driver and co-worker.That wasn’t an issue for Mike Hamm. In 2012, he became Anthony’s new assistantand embraced the plan of spending part of their days delivering packages as a team. The pair called their venture Anthony at Your Service, signed a few customers and set out in Hamm’s lorry.Seven years later, boxes awaiting distribution are piled on the porch of the home. Anthony, 30, shares with Deborah and her husband, David, a lawyer. The company now has two-dozen delivery teams-each comprising a contractor with an intellectual disability and their support-worker contractor-in Edmonton and Calgary.Launching a company that employs 24 contractors with intellectual disabilities, and all the logistics that come along with that, wasn’t the original plan, Deborah says. But the realities of delivery work - the peaks and valleys in demand, the long hours - meant that Anthony and Hamm couldn’t shoulder the load alone. And the feedback she received from Alberta’s autistic and intellectually disabled communities suggested they wanted to work for a company that understood them.Running Anthony at Your Service has become Deborah’s full-time, and she gave up her psychotherapy practice and the presidency of Autism Society Alberta a couple years ago. “What I’m doing for Anthony now has made more difference in his life than any of that other work,” she says. “We want to create jobs for people with all kinds of abilities and disabilities. ”4. What’s the future of the persons with intellectual disabilities according to Deborah?A. They will lose their lives.B. They will get well-paid jobs.C. They will clean plates in restaurants.D. They will find it hard to find a decent job.5. What does the underlined word “courier” mean in the 3rd paragraph?A. Accountant.B. Barber.C. Deliveryman.D. Engineer.6. What can be inferred from the passage?A. David launched the company for his son.B. Anthony’s contractors are mainly disabled.C. Deborah gave up her original job unwillingly.D. Mike Hamm is an intellectually disabled person.7. Which of the following words can best describe Deborah Barrett?A. Accessible.B. Caring.C. Humorous.D. Modest.CJellyfish are unusual creatures. They’re neither fish nor jelly. Some are among the most colourful creatures in the world, but it’s best to look but not touch these invertebrates(无脊椎动物). Not only are they very fragile creatures, but many give a painful sting, and some are even deadly. Whether you admire them in an aquarium or try to avoid them in the wild, you won’t be able to get these fascinating jellyfish facts out of your head.Here’s a jellyfish fact that might come in handy: There are several names for a group of jellyfish. They include smack, bloom, and swarm. Choose the word you prefer depending on whether you think the jellyfish pack looks like a garden of blooming flowers or more like a frightening pack of stingers, and whether you’re admiring them at an aquarium or if you and your fellow snorkelers are surrounded.Jellyfish have two main forms in their life cycle that look quite different from each other. Scientific American explains that an adult jellyfish, called a medusa, has a bell-shaped body with tentacles(触须)flowing down below it. Young jellyfish, called polyps, look more like sea anemones, with shorter tentacles that flow up above the main body. Medusas reproduce by releasing eggs.Melanie Roberts, Senior Aquarist at SeaWorld Orlando, says that the largest jellyfish in the world is a lion’s mane jellyfish. The body of this beautiful orange jelly can grow up to three feet in diameter. With its 12,000 tentacles that can grow 120 feet long, Oceana. org adds that the lion’s mane jelly compares in size to the planet’s largest animal: the blue whale.Regardless of their size, jellyfish are mostly made of water. In fact, they’re about 95 per cent water. These creatures don’t have brains, blood, or bones. And most jellyfish don’t have eyes. Jellyfish also use their mouths both for eating and for waste removal.8. Why can’t we touch jellyfish?A. Because they may be stung.B. Because they may die easily.C. Because they may feel painful.D. Because they may hurt people.9. What are jellyfish named after?A. Its size.B. Its color.C. Its appearance.D. Its lifestyle.10. What can we learn from the passage?A. Mouth is an important organ for jellyfish.B. Polyps can clone themselves by laying eggs.C. The largest jellyfish in the world is 120 feet long.D. Medusas have tentacles flowing up above the body.11. What can be the best title of the passage?A. Several facts about jellyfish.B. The two main forms of jellyfish.C. Jellyfish are neither fish nor jelly.D. Jellyfish have many different names.DAny time we burn fossil fuels, we’re pumping fine particulate matter(细颗粒物)from oil, gas and other toxins(毒素)into the air. “Some of these carbon particles can persist in the lungs for decades,”says Dr. Don Sin, a respirologist and director of the Centre for Heart Lung Innovation in Vancouver.Over 7,000 Canadians died from complications due to poor air quality in 2015.A study in the European Heart Journal earlier this year found that air pollution now kills 8. 8 million people worldwide per year -more than tobacco smoking.Sin adds that women’s lungs seem particularly easy to get cancer from pollution. Currently, 10,000 Canadian women die of lung cancer every year, and 15 per cent of new cases are people who have never smoked. “In Canada, lung-cancer deaths in female non-smokers will very soon probably outnumber the deaths from breast cancer, because lung cancer is so deadly,” he says.Contributing to air pollution are the 8,000 wildfires we experience every year in Canada, like those that destroyed large areas of Alberta this past spring. These are increasing in frequency and intensity with our hotter, drier spells. A study in the Canadian Journal of Emergency Medicine found that prescriptions for an asthma and COPD drug rose by 22 per cent in the Yellowknife region in the summer of 2014, when it was surrounded by wildfire smoke. The number of ER visits for breathingproblems was 42 per cent higher; for children, it more than doubled.Another threat to breathing is mould, which is a concern in areas with repeated flooding, such as around New Brunswick’s Saint John River, where floodwaters have been in homes for two years in a row and displaced more than 200 families. Moulds produce toxins and spores that can trigger allergic reactions or infections if taken in. Rising sea levels and increased urban development, combined with intense rainfalls, mean we will see a lot more of it.To avoid breathing polluted air, wear a mask rated N95-not a surgical mask, which is useless, says Sin. “Those are too thin and easily torn. They won’t protect you at all from air particles. ”On bad-air days, get your exercise indoors, for instance by walking in an air-conditioned mall.12. Which of the following is True according to the passage?A. 15 per cent of Canadian women have never smoked.B. 1,000 Canadian women die of lung cancer every year.C. Air pollution has killed 8. 8 million people in the world.D. Over 7,000 Canadians died as a result of air pollution in 2015.13. What may cause the wildfires in Canada according to the passage?A. Hot weather.B. Cigarette end.C. Dry plants.D. Poor management.14. What of the following is NOT a factor to produce moulds?A. Sea levels rising.B. Development of countryside.C. Lots of rainfalls.D. Growth of city.15. What should be suggested to prevent breathing polluted air?A. Wearing a surgical mask.B. Taking exercise.C. Walking indoors.D. Sleeping longer hours.第二节(共5小题；每小题3分，满分15分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
2020年5月清华大学中学生标准学术能力诊断性测试高三英语卷附答案
2020年5月清华大学中学生标准学术能力诊断性测试高三英语卷【试卷共150分，考试时间100分钟】第一部分阅读理解（共两节，满分60分）第一节（共15小题；每小题3分，满分45分）ASummer is that time of this year2019when everyone looks to escape from the boring activities of life.So bring your kids to join us to have fun in the summer camp.Outdoor Word Game:All you need to do is setting up many huge letters that can be easily moved.These letters will help kids spell out certain words.Teenagers would also love something like this as it gives them the opportunity to invest their time in learning new words.Spray Painting:To bring out the creativity in a person,an activity centered on spray painting is the perfect way to get those creative juices flowing.All you need to do is providing plain white T-shirts and some cans of colored spray paint.It will be quite surprising to see some of the original ideas that will flow from individuals.Outdoor Twister:A person will be in charge of monitoring the game and will call out colors which can be placed outdoors.Participants have the task of placing either their hands or legs on the same color.A fun and exciting game focuses on hand-eye coordination（协调）.The Maze（迷宫）:One of the funniest games is the hallway maze game where a maze is constructed from either toilet paper or strings of paper.The chosen participant is then asked to make his way through the maze within a limited time without touching paper.This is one of the best and entertaining summer camp ideas for kids and adults also.1.Which activity most probably needs some imagination?A．Outdoor Word Game.B．Spray Painting.C．Outdoor Twister.D．The Maze.2.Which of the following is TRUE according to the passage?A.The maze is made of toilet paper in The Maze.B.You have to spray juice on your T-shirt in Spray Painting.C.Outdoors Twister tests whether you are good at controlling your body movement.D.You have to bring some huge letters to play in Outdoor Word Games.3.Who is the article intended for?A.Parents.B．Children.C．Teachers.D．Teenagers.BWhat makes a person sexy?Looks,talent,public image and how we accordingly view their personality all play into why we find ourselves attracted to certain celebrities and public figures.Every year,People put it all together when they name their“Sexiest Man Alive”.This year,the magazine decided that United States musician John Roger Stephens,better known as John Legend,has the full package.The title comes following some impressive achievements for the40-year-old.He is among the youngest people to win an Emmy,Grammy,Oscar and Tony award,and the first African-American man to win all four of them.With numerous awards and nominations,an Ivy-League degree,and a handsome face,Legend has gained huge popularity worldwide.However,his dedication to family life maybe what wins over many.After getting married to US model Chrissy Teigen in2013,Legend is the father of one son and one daughter.He’s not shy about telling the world their love is permanent.On the inside of Legend’s arm,there is a tattoo that says“Chrissy Luna Miles”,the names of his wife and children.In fact,Legend has gained strength from his family since childhood.He still remembers the days when his family would gather around his grandmother’s piano to sing Christmas songs.This inspired his passion for music.His best-known single,All of Me,is a love song to his wife.When he performed it at the2014Grammy Awards,many were touched by his delicate voice and the deep love beneath.“The more you know someone,the more you’re inspired by your relationship,”Legend told LA Confidential Magazine.“You have to grow enough to be able to write that song with sincerity and authenticity.”Despite his onstage confidence,Legend had to work to become a legend.As a teenager,he was the smallest kid in class.“I was always less mature,less at ease socially.I had plenty of awkward times,”he told People.“Most of your teenage years, into your twenties,you’re still figuring out who you are,how you present yourself to the world...Eventually,I think you get more at ease with yourself.”Indeed,knowing who you are and be yourself could be the real key to attractiveness.4.What plays the biggest part in making Legend popular worldwide?A．High-level education.B．Handsome look.C．Efforts put in family.D．Talent in music.5.What does the third paragraph mainly talk about?A.Legend’s hobby as a boy.B.Legend’s family members.C.The secret behind Legend’s success.D．Composing background of the songAll of Me.6.What can you infer from the passage?A.Legend is proud of his success in music.B.Legend’s interest in music originates from his family.C.Legend is the first black singer who won the Grammy award.D.Legend received the title“Sexiest Man Alive”before he got married.7.What is essential to attractiveness according to Legend?A.Being more mature.B.Being true to yourself.C.Having onstage confidence.D.Having attractive appearance.CWhat makes people trustworthy?Do they always tell the truth?Do they always keep their promises?In the near future,voluntary blood donations might be used as a clue to prove someone’s trustworthiness.On Nov19,the National Health Commission(NHC)and other departments jointly released a document urging the social credit system to include voluntary blood donations.An incentive mechanism（激励机制）is also recommended,to provide donors with more conveniences and rewards like preferential treatment in using public facilities or visiting government-run parks,China Daily reported.“We need to show we care about donors so they feel honored,”Liu Jiang,director of Beijing’s blood donation office,told CCTV.Indeed,donating blood is key to saving many lives.Due to blood’s very limited shelf life,regular blood donations are needed from a sufficient number of healthy people.This ensures that safe blood will be available whenever and wherever it is needed,according to the World Health Organization.However,the notice received mixed reviews on social media,with some people questioning whether it was necessary to include voluntary blood donation in the social credit system,according to the South China Morning Post.The system records things like a person’s career information,and payments for credit cards or other debt expenses are used to tellwhether a person or company is trustworthy.People who cannot pay debts on time would have a worse credit score,resulting in more difficulties borrowing money from banks,reported the People’s Daily.Many Sina Weibo users believe that blood donations should be voluntary.They say it has little to do with social credit.Others doubt whether it is appropriate to reward this action because some people would donate blood for reasons other than helping save people’s lives.Guangming Daily commented that only acts closely linked to personal credit should be included in the social credit system.A voluntary blood donor might refuse to pay his or her debts,while someone who doesn’t donate blood might have a perfect credit record,it noted.8.What benefit can voluntary blood donors get according to the2nd paragraph?A．Free park tour.B．Free treatment in hospitals.C．Running in government parks.D．Priority in using public facilities.9.Why are blood donations regularly needed?A.Blood can’t be stored for long.B.Some donated blood is not healthy.C.Fewer people are willing to donate blood.D.More and more people need blood to get treated.10.What can you learn from the last paragraph?A.Many blood donors refuse to pay his or her debts.B.Whoever donates blood will have a perfect credit record.C.It’s right to reward blood donators for they save people’s lives.D.Some people agree that voluntary blood donation shouldn’t belinked to social credit.11．What’s the author’s attitude to using voluntaryblood donations to prove trustworthiness?A．Positive.B．Objective.C．Indifferent D．Negative.DFive years ago,UK schools began to learn Shanghai’s math teaching methods on account of top scores produced by Chinese teenagers in a global academic evaluation. This test is called the Program for International Student Assessment(PISA),run by the organization for Economic Cooperation and Development(OECD).Taking around three hours on computers,it mainly focuses on15-year-olds’reading,math and science abilities.Earlier this month,the latest test results were published.Students from Beijing and Shanghai,as well as Jiangsu and Zhejiang provinces,outperformed students from the other 78participating education systems inmathematics and science by a wide margin.In reading comprehension scores,only Singapore came close.Chinese mainland students first took the tests in 2009,with Shanghai topping the scores.The city claimed the top spot again in 2012.The PISA rankings aroused global interest in Chinese teaching methods and as aresult,Britain increased exchanges with Chinese schools to improve its matheducation.Nearly 600teachers from Britain and China,mainly from primary schools,have taken part in the exchange since 2014,and around 5,000of Britain’s 16,000primary schools have adopted the Shanghai math teaching method.In the latest PISA test,Chinese mainland students averaged 591points in math —more than 100points higher than the OECD average.British students averaged 502,jumping from27th place three years ago to 18th in the math rankings.Philip Avery,director of education for the Bohunt Education Trust,UK,said,“We’ve benefited fromworking with Chinese partners for the high quality of lesson planning and teaching for memorization in China.Our Chinese partners have benefited from our approach to the development of character,focus on innovation and application of knowledge.”However,Zhang Xuanmin,who is in charge of the PISA project in Shanghai,pointsout that besides basic education,Chinese students still need to improve their social and emotional competencies.12.Which of the following is TRUE according to the passage?A ．UK teenagers are poorly-educated.B ．UK schools’teaching methods are out of fashion.C ．Teenagers in Shanghai got higher scores in PISA.D ．Teenagers in Shanghai are the best students in the world.13.What does the underlined word mean in the 2nd paragraph?14.What’s probably the average math point of OECD in the latest PISA test?15．What can be indicated by Philip Avery’s words?A.The exchange program is a win-win situation.B.Chinese students still have a long way to go ineducation.C ．UK schools get more benefits from the exchange program.D ．UK teenagers have gained a lot ofimprovement in math learning.A ．Laugh at.B ．Look up to.C ．get along with.D ．be superior to.A ．302.B ．490.C ．502.D ．591.第二节（共5小题；每小题3分，满分15分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

第一部分阅读理解（共两节，满分60 分）第一节（共15 小题；每小题 3 分，满分45 分）AFour of the Oldest Buildings in the WorldKnap of HowarOne of the oldest buildings in the world is the Knap of Howar, which dates back to 3700-3500 BCE. The farmhouse is one of the oldest, still-standing stone houses in Europe. It includes two stone homes linked through a hidden passage and joint walls. Archaeologists say Irish or Scottish monks could be the first builders and residents of the Knap of Howar. Although the house is still standing, these abandoned places around the world are better candidates for restoration.Ggantija TemplesThe Megalithic Temples of Malta, or the Ggantija Temples, date back to 3600 to 3200 BCE. The two temples on the island of Malta are UNESCO World Heritage sites. It ' the oldest free-standing monuments in the world. Archaeologists think the temple was used for ritual animal sacrifices.Shunet el-ZebibShunet el-Zebib is partially standing, but mostly in ruins. It 'ssti ll, however, one of the oldest buildings in the world. The Egyptian temple built in 2750 BCE is of mud and brick. It has an underground tomb as well as an above-ground complex. Architecturally, it ' s a nod t the Egyptian pyramids soon to come.Tomb of CyrusBuilt in 530 BCE, the Tomb of Cyrus is one of Iran ' s World Heritage Sites and one oldest buildings on the planet. It 'asls o believed to be one of the first earthquake-protected structures in the world, according to Atlas Obscura. The base isolating used on the tomb·1·protects the main structure from moving apart from the foundation.1. What do the four buildings have in common?A. All of them are located in Europe.B. All of them are made of stone and mud.C. All of them are UNESCO World Heritage Sites.D. All of them were built before the birth of Christ.2. Which of the four buildings may be the strongest?A. Knap of Howar.B. Ggantija Temples.C. Shunet el-Zebib.D. Tomb of Cyrus.3. Which of the following is True according to the passage?A. Shunet el-Zebib is earthquake protected.B. Tomb of Cyrus has an underground tomb.C. Ggantija Temples are built by Irish monks.D. Knap of Howar may be the oldest building among the four.BIn the summer of 2010, Deborah Barrett and her son, Anthony, walked out of a restaurant near the Edmonton high school from which he'dg raduated two years earlier. They had volunteered to wash dishes there to give Anthony something to do, but when they went out, the sun sliced through the clouds and Deborah had a realization: my kid is not spending his life in a dish pit.Cleaning plates isn't the only option for high-school graduates. But Anthony has autism（自闭症）and is mostly non-verbal, aside from short words in answer to yes-or-no questions and the Eeeee sounds he makes when he'es xcited, happy or frustrated. Once a person with intellectual disabilities ages out of school, “ There 'nos life for them, ”D eborah says. Programs end, and jobs are usually humble.As her son entered his 20s, Deborah thought about what he could do and what he enjoyed. Among his likes: being driven around and carrying things, as well as seeing new places but not staying long. Maybe he could be a courie?r The catch: Anthony doesn 't move fast, and courier jobs would require his support staff to be his driver and co-worker.That wasn 't an issue for Mike Hamm. In 2012, hebecame Anthony 's new assistant and embraced the plan of spending part of their days delivering packages as a team. The pair called their venture Anthony at Your Service, signed a few customers and set out in HammSeven years later, boxes awaiting distribution are piled on the porch of the home. Anthony, 30, shares with Deborah and her husband, David, a lawyer. The company now has two-dozen delivery teams-each comprising a contractor with an intellectual disability and their support-worker contractor-in Edmonton and Calgary.Launching a company that employs 24 contractors with intellectual disabilities, and all the logistics that come along with that, wasn 't the original plan, Deborah says. But the realitie delivery work - the peaks and valleys in demand, the long hours - meant that Anthony and Hamm couldn ' t shoulder the load alone. And the feedback she received from Alberta and intellectually disabled communities suggestedt hey wanted to work for a company that understood them.Running Anthony at Your Service has become Deborah -tim'e,s a fnudll she gave up herpsychotherapy practice and the presidency of Autism Society Alberta a couple years ago. “What I'm doing for Anthony n ohwas made more difference in his life than any of that other work, ”s he says. “Wew ant to create jobs for people with all kinds of abilities and disabilities. ”4. What's the future of the persons with intellectual disabilities according to Deborah?A. They will lose their lives.B. They will get well-paid jobs.C. They will clean plates in restaurants.D. They will find it hard to find a decent job.5. What does the underlined word“ courier” mean in the 3rd paragraph?A. Accountant.B. Barber.C. Deliveryman.D. Engineer.6. What can be inferred from the passage?A. David launched the company for his son.B. Anthony's contractors are mainly disabled.C. Deborah gave up her original job unwillingly.D. Mike Hamm is an intellectually disabled person.7. Which of the following words can best describe Deborah Barrett?A. Accessible.B. Caring.C. Humorous.D. Modest.CJellyfish are unusual creatures. They ' re neither fish nor jelly. Some are among the mocolourful creatures in the world, but it 's best to look but not touch these invertebrates无（脊椎动物）. Not only are they very fragile creatures, but many give a painful sting, and some are even deadly. Whether you admire them in an aquarium or try to avoid them in the wild, you won' t be able to get these fascinatinjegl lyfish facts out of your head.Here' s a jellyfish fact that might come in handy: There are several names for a group of jellyfish. They include smack, bloom, and swarm. Choose the word you prefer depending on whether you think the jellyfish pack looks like a garden of blooming flowers or more like a frightening pack of stingers, and whether you ' re admiring them at an aquarium or if you your fellow snorkelers are surrounded.Jellyfish have two main forms in their life cycle that look quite different from each other. Scientific American explains that an adult jellyfish, called a medusa, has a bell-shaped body with tentacles（触须）flowing down below it. Young jellyfish, called polyps, look more like sea anemones, with shorter tentacles that flow up above the main body. Medusas reproduce by releasing eggs.Melanie Roberts, Senior Aquarist at SeaWorld Orlando, says that the largest jellyfish in the world is a lion ' s mane jellyfishh. eT body of this beautiful orange jelly can grow up to three feet in diameter. With its 12,000 tentacles that can grow 120 feet long, Oceana. org adds that the lion 's mane jelly compares in size to the planet ' s largest animal: the blue Regardless of their size, jellyfish are mostly made of water. In fact, they 're a cent water. These creatures don ' t have brains, blood, or bones. And most jellyfish don eyes. Jellyfish also use their mouths both for eating and for waste removal.8. Why can't we touch jellyfish?A. Because they may be stung.B. Because they may die easily.C. Because they may feel painful.D. Because they may hurt people.9. What are jellyfish named after?A. Its size.B. Its color.C. Its appearance.D. Its lifestyle.10. What can we learn from the passage?A. Mouth is an important organ for jellyfish.B. Polyps can clone themselves by laying eggs.C. The largest jellyfish in the world is 120 feet long.D. Medusas have tentacles flowing up above the body.11. What can be the best title of the passage?A. Several facts about jellyfish.B. The two main forms of jellyfish.C. Jellyfish are neither fish nor jelly.D. Jellyfish have many different names.DAny time we burn fossil fuels, we 're pumping fine particulate matter（细颗粒物）from oil, gas and other toxins（毒素）into the air. “Some of these carbon particles can persist in the lungs for decades”, says Dr. Don Sin, a respirologist and director of the Centre for Heart Lung Innovation in Vancouver.Over 7,000 Canadians died from complications due to poor air quality in 2015. A study in the European Heart Journal earlier this year found that air pollution now kills 8. 8 million people worldwide per year -more than tobacco smoking.Sin adds that women' s lungs seem particularly easy to get cancer from pollution. Currently, 10,000 Canadian women die of lung cancer every year, and 15 per cent of new cases are people who have never smoked. “In Canada, lung-cancer deaths in female non-smokers will very soon probably outnumber the deaths from breast cancer, because lung cancer is so deadly, ” he says.Contributing to air pollution are the 8,000 wildfires we experience every year in Canada, like those that destroyed large areas of Alberta this past spring. These are increasing in frequency and intensity with our hotter, drier spells. A study in the Canadian Journal of Emergency Medicine found that prescriptions for an asthma and COPD drug rose by 22 per cent in the Yellowknife region in the summer of 2014, when it was surrounded by wildfire smoke. The number of ER visits for breathingproblems was 42 per cent higher; for children, it more than doubled.Another threat to breathing is mould, which is a concern in areas with repeated flooding, such as around New Brunswick 's Saint John River, where floodwaters have been in homes for two years in a row and displaced more than 200 families. Moulds produce toxins and spores that can trigger allergic reactions or infections if taken in. Rising sea levels and increased urban development, combined with intense rainfalls, mean we will see a lot more of it.To avoid breathing polluted air, wear a mask rated N95-not a surgical mask, which is useless, saysS in. “ Those are too thin and easily torn. They won 't protect you at all fro particles. ” On bad-air days, get your exercise indoors, for instance by walking in an air-conditioned mall.12. Which of the following is True according to the passage?A. 15 per cent of Canadian women have never smoked.B. 1,000 Canadian women die of lung cancer every year.C. Air pollution has killed 8. 8 million people in the world.D. Over 7,000 Canadians died as a result of air pollution in 2015.13. What may cause the wildfires in Canada according to the passage?A. Hot weather.B. Cigarette end.C. Dry plants.D. Poor management.14. What of the following is NOT a factor to produce moulds?A. Sea levels rising.B. Development of countryside.C. Lots of rainfalls.D. Growth of city.15. What should be suggested to prevent breathing polluted air?A. Wearing a surgical mask.B. Taking exercise.C. Walking indoors.D. Sleeping longer hours.第二节（共5小题；每小题3分，满分15分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。

中学生标准学术能力诊断性测试2020年1月测试英语试卷本试卷共150分，考试时间100分钟。
第一部分阅读理解(共两节，满分60分)第一节(共15小题；每小题3分，满分45分)AFour of the Oldest Buildings in the WorldKnap of HowarOne of the oldest buildings in the world is the Knap of Howar, which dates back to 3700-3500 BCE. The farmhouse is one of the oldest, still-standing stone houses in Europe. It includes two stone homes linked through a hidden passage and joint walls. Archaeologists say Irish or Scottish monks could be the first builders and residents of the Knap of Howar. Although the house is still standing, these abandoned places around the world are better candidates for restoration. Ggantija TemplesThe Megalithic Temples of Malta, or the Ggantija Temples, date back to 3600 to 3200 BCE. The two temples on the island of Malta are UNESCO World Heritage sites. It’s one of the oldest free-standing monuments in the world. Archaeologists think the temple was used for ritual animal sacrifices.Shunet el-ZebibShunet el-Zebib is partially standing, but mostly in ruins. It’s still, however, one of the oldest buildings in the world. The Egyptian temple built in 2750 BCE is of mud and brick. It has an underground tomb as well as an above-ground complex. Architecturally, it’s a nod to the Egyptian pyramids soon to come.Tomb of CyrusBuilt in 530 BCE, the Tomb of Cyrus is one of Iran’s World Heritage Sites and one of the oldest buildings on the planet. It’s also believed to be one of the first earthquake-protected structures in the world, according to Atlas Obscura. The base isolating used on the tomb protects the main structure from moving apart from the foundation.1. What do the four buildings have in common?A. All of them are located in Europe.B. All of them are made of stone and mud.C. All of them are UNESCO World Heritage Sites.D. All of them were built before the birth of Christ.2. Which of the four buildings may be the strongest?A. Knap of Howar.B. Ggantija Temples.C. Shunet el-Zebib.D. Tomb of Cyrus.3. Which of the following is True according to the passage?A. Shunet el-Zebib is earthquake protected.B. Tomb of Cyrus has an underground tomb.C. Ggantija Temples are built by Irish monks.D. Knap of Howar may be the oldest building among the four.BIn the summer of 2010, Deborah Barrett and her son, Anthony, walked out of a restaurant near the Edmonton high school from which he’d graduated two years earlier. They had volunteered to wash dishes there to give Anthony something to do, but when they went out, the sun sliced through the clouds and Deborah had a realization: my kid is not spending his life in a dish pit.Cleaning plates isn’t the only option for high-school graduates. But Anthony has autism(自闭症)and is mostly non-verbal, aside from short words in answer to yes-or-no questions and the Eeeee sounds he makes when he’s excited, happy or frustrated. Once a person with intellectual disabilities ages out of school, “There’s no life for them,” Deborah says. Programs end, and jobs are usually humble.As her son entered his 20s, Deborah thought about what he could do and what he enjoyed. Among his likes: being driven around and carrying things, as well as seeing new places but not staying long. Maybe he could be a courier? The catch: Anthony doesn’t move fast, and courier jobs would require his support staff to be his driver and co-worker.That wasn’t an issue for Mike Hamm. In 2012, he became Anthony’s new assistant and embraced the plan of spending part of their days delivering packages as a team. The pair called their venture Anthony at Your Service, signed a few customers and set out in Hamm’s lorry.Seven years later, boxes awaiting distribution are piled on the porch of the home. Anthony, 30, shares with Deborah and her husband, David, a lawyer. The company now has two-dozen delivery teams-each comprising a contractor with an intellectual disability and their support-worker contractor-in Edmonton and Calgary.Launching a company that employs 24 contractors with intellectual disabilities, and all the logistics that come along with that, wasn’t the original plan, Deborah says. But the realities of delivery work - the peaks and valleys in demand, the long hours - meant that Anthony and Hamm couldn’t shoulder the load alone. And the feedback she received from Alberta’s autistic and intellectually disabled communities suggested they wanted to work for a company that understood them.Running Anthony at Your Service has become Deborah’s full-time, and she gave up her psychotherapy practice and the presidency of Autism Society Alberta a couple years ago. “What I’m doing for Anthony now has made more difference in his life than any of that other work,”she says. “We want to create jobs for people with all kinds of abilities and disabilities. ”4. What’s the future of the persons with intellectual disabilities according to Deborah?A. They will lose their lives.B. They will get well-paid jobs.C. They will clean plates in restaurants.D. They will find it hard to find a decent job.5. What does the underlined word “courier” mean in the 3rd paragraph?A. Accountant.B. Barber.C. Deliveryman.D. Engineer.6. What can be inferred from the passage?A. David launched the company for his son.B. Anthony’s contractors are mainly disabled.C. Deborah gave up her original job unwillingly.D. Mike Hamm is an intellectually disabled person.7. Which of the following words can best describe Deborah Barrett?A. Accessible.B. Caring.C. Humorous.D. Modest.CJellyfish are unusual creatures. They’re neither fish nor jelly. Some are among the most colourful creatures in the world, but it’s best to look but not touch these invertebrates(无脊椎动物). Not only are they very fragile creatures, but many give a painful sting, and some are even deadly. Whether you admire them in an aquarium or try to avoid them in the wild, you won’t be able to get these fascinating jellyfish facts out of your head.Here’s a jellyfish fact that might come in handy: There are several names for a group of jellyfish. They include smack, bloom, and swarm. Choose the word you prefer depending on whether you think the jellyfish pack looks like a garden of blooming flowers or more like a frighteningpack of stingers, and whether you’re admiring them at an aquarium or if you and your fellow snorkelers are surrounded.Jellyfish have two main forms in their life cycle that look quite different from each other. Scientific American explains that an adult jellyfish, called a medusa, has a bell-shaped body with tentacles(触须)flowing down below it. Young jellyfish, called polyps, look more like sea anemones, with shorter tentacles that flow up above the main body. Medusas reproduce by releasing eggs.Melanie Roberts, Senior Aquarist at SeaWorld Orlando, says that the largest jellyfish in the world is a lion’s mane jellyfish. The body of this beautiful orange jelly can grow up to three feet in diameter. With its 12,000 tentacles that can grow 120 feet long, Oceana. org adds that the lion’s mane jelly compares in size to the planet’s largest animal: the blue whale.Regardless of their size, jellyfish are mostly made of water. In fact, they’re about 95 per cent water. These creatures don’t have brains, blood, or bones. And most jellyfish don’t have eyes. Jellyfish also use their mouths both for eating and for waste removal.8. Why can’t we touch jellyfish?A. Because they may be stung.B. Because they may die easily.C. Because they may feel painful.D. Because they may hurt people.9. What are jellyfish named after?A. Its size.B. Its color.C. Its appearance.D. Its lifestyle.10. What can we learn from the passage?A. Mouth is an important organ for jellyfish.B. Polyps can clone themselves by laying eggs.C. The largest jellyfish in the world is 120 feet long.D. Medusas have tentacles flowing up above the body.11. What can be the best title of the passage?A. Several facts about jellyfish.B. The two main forms of jellyfish.C. Jellyfish are neither fish nor jelly.D. Jellyfish have many different names.DAny time we burn fossil fuels, we’re pumping fine particulate matter(细颗粒物)from oil, gas and other toxins(毒素)into the air. “Some of these carbon particles can persist in the lungs for decades,” says Dr. Don Sin, a respirologist and director of the Centre for Heart LungInnovation in Vancouver.Over 7,000 Canadians died from complications due to poor air quality in 2015. A study in the European Heart Journal earlier this year found that air pollution now kills 8. 8 million people worldwide per year -more than tobacco smoking.Sin adds that women’s lungs seem particularly easy to get cancer from pollution. Currently, 10,000 Canadian women die of lung cancer every year, and 15 per cent of new cases are people who have never smoked. “In Canada, lung-cancer deaths in female non-smokers will very soon probably outnumber the deaths from breast cancer, because lung cancer is so deadly,” he says.Contributing to air pollution are the 8,000 wildfires we experience every year in Canada, like those that destroyed large areas of Alberta this past spring. These are increasing in frequency and intensity with our hotter, drier spells. A study in the Canadian Journal of Emergency Medicine found that prescriptions for an asthma and COPD drug rose by 22 per cent in the Yellowknife region in the summer of 2014, when it was surrounded by wildfire smoke. The number of ER visits for breathing problems was 42 per cent higher; for children, it more than doubled.Another threat to breathing is mould, which is a concern in areas with repeated flooding, such as around New Brunswick’s Saint John River, where floodwaters have been in homes for two years in a row and displaced more than 200 families. Moulds produce toxins and spores that can trigger allergic reactions or infections if taken in. Rising sea levels and increased urban development, combined with intense rainfalls, mean we will see a lot more of it.To avoid breathing polluted air, wear a mask rated N95-not a surgical mask, which is useless, says Sin. “Those are too thin and easily torn. They won’t protect you at all from air particles. ”On bad-air days, get your exercise indoors, for instance by walking in an air-conditioned mall.12. Which of the following is True according to the passage?A. 15 per cent of Canadian women have never smoked.B. 1,000 Canadian women die of lung cancer every year.C. Air pollution has killed 8. 8 million people in the world.D. Over 7,000 Canadians died as a result of air pollution in 2015.13. What may cause the wildfires in Canada according to the passage?A. Hot weather.B. Cigarette end.C. Dry plants.D. Poor management.14. What of the following is NOT a factor to produce moulds?A. Sea levels rising.B. Development of countryside.C. Lots of rainfalls.D. Growth of city.15. What should be suggested to prevent breathing polluted air?A. Wearing a surgical mask.B. Taking exercise.C. Walking indoors.D. Sleeping longer hours.第二节(共5小题；每小题3分，满分15分)根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
