When I was nine years old, I learned ho w to make a coin disappear. I’d read The Lord of the Rings and ventured into the adult section of the library to search for a book of spells—nine beingthatcuriousageat whichyou’re oldenoughtoworkthroughmorethan1,200pagesoffantasyliteratur ebut young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand technique, and I dedicated the next months topractice.At first the magic wasn’t any good. At first it wasn’t even magic; it was just a trick—a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over andover,athousandtimes inaday,andaftertwoweeks ofthismymomgotacarpetfromthehardwarestoreand placed it under the mirror to mufflethe sound of the coin falling again andagain.I had heard my dad work through passages of new music on the piano, so I knew how to practice—slowly, deliberately,goingforprecisionratherthanspeed.OnedayItriedthe illusioninthemirrorandthe coinvanished. It did not look like a magic trick. It looked like amiracle.One of the lessons you learn very early on as a magician isthat the most amazing part of a trick has nothing to do with the secret. The secret is simple and often dull: a hidden piece of tape, a small mirror, a duplicate playing card, diversion of the audience’s attention. In this case, the secret was a series of covert ( 暗中的) technique to hide the coin behind my hand in the act of opening it, a dance of the fingers that I learned so completelyI didn’t evenhavetothink.

In captivity( 圈养), they can be trained to complete complex tasks such as jumping through hoops and somersaulting through the air.But their intelligence doesn’t stop there. In a recent study of cetaceans (鲸目动物)--a groupof animals that includes dolphins and whales--researchers created a list of intelligent behaviorsobserved in 90 different cetacean species, reported the Guardian. For example, the smartest cetaceans hunt in groups, share knowledge through mimicry (模仿) and even care for each other's children. Some even consider their behavior to be human-like.“There is the saying that ‘it takes a village to raise a child’ seems to be true for both whales and humans,”Michael Muthukrishna of the London School of Economics, co-author of the study, told the Guardian.However,cetaceans don’t justusetheir brainpowerforsurvival.The studysuggeststhatdolphinsmighteven gossip. That's because some species greet each other with specific whistles, just as humans greet each other by name, the Guardian reported. Sometimes, agroup of dolphins whistles the “name” of a dolphin that isn't there. Could they be speaking abouttheir “friend” behind itsback?For the researchers, dolphin small talk is a big deal. As they found that the most social cetaceans also have the largest brains, they argue that cetacean intelligence developed to meet thedemands of complex social groups.Knownasthe “cultural brainhypothesis (假设),” ithadonly beenusedtoexplaintheintelligenceofhumans andother primates (灵长目动物). Thenewstudyaimedtofindacommonpathwayfortheevolutionof intelligence among biologically3differentspecies.“It is interesting to think that whale and human brains are different in their structure but have brought us to the same patterns in behavior, ” Luke Rendell, a biologist at the University of St Andrews, told the Guardian.Indeed,westillhavealottolearnaboutourintelligentocean-dwellingneighbors.“Wedon’thavetolo okat other planets to look for aliens,” Muthukrishna told the Guardian, “because we know that underwater there are these amazing species with so man y parallels to us in their complex behaviors.”8.The recent study was intended to ____.A.learn more about intelligent creatures of theseaB.explain the intelligence of humans andcetaceansC.create a list of intelligent behaviors of different cetaceanspeciesD.see whether the intelligence of different species evolved in the sameway9.The implied meaning of the underlined part in Paragraph 3isthat ____ _.A.villagers have the responsibility to raise any child in thevillageB.like human beings, whales even he lp raise each other’s babiesC.cetaceans have social behaviors very similarto human beingsD.it is not easy for one villager to take care of his or her ownchild10.Itcanbe inferredfromthe passagethat____ .A.it is unnecessary to look for aliens and do research intothemB.some cetaceans have the same intelligence as humanbeingsC.both dolphins and whales greet each other with specificwhistlesD.both dolphins and whales have a lot in common with humans inbehaviors11.What is the best title for thispassage?A.

Since ancient times, medics have relied on their sense of smelltohelpthemworkoutwhatiswrongwiththeirpatients. Fruityodors (气味) onthebreath, forexample, let themmonitortheconditionofdiabetics (糖尿病病人).But doctors can, as it were, smell only what they can smell—and many compounds characteristic of disease are odorless. To deal with this limitation, Hossam Haick, a chemical4engineer at the T echnion Israel Institute of Technology in Haifa, has developed a device which, he claims, can do work thatthe human nose cannot.The idea behind Dr. Haick’s invention is not ne w. Many diagnostic “breathalysers” already exist, and sniffer dogs,too,canbe trainedtodetectillnessessuchascancer.Mostofthese approaches,though,are disease-specific. Dr. Haick wanted to generalize theprocess.As he describes in ACS Nano, he and his colleagues created a series of electrodes made of carbon nanotubes (纳米碳管).

The combined changes produced an electrical fingerprint that would be diagnostic of the disease a patient was sufferingfrom.To test their invention, Dr. Haick and his colleagues collected 2,808 breath samples from 1,404 patients who were suffering from at least one of the diseases. Its success varied. It could distinguish between samples from patientssufferingfromgastriccancerandbladdercanceronly64%ofthetime. Atdistinguishinglungcancerfrom head and neck cancer it was, though, 100% successful. Overall, it got things right 86% of the time.

Imaginate FestivalC. The RoyalEdinburghMilitary TattooD.EdinburghInternational Film FestivalBPaper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.Paper is mainly made from cellulose (纤维素),which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!4. What can we infer from the text?A. The use of recycled paper will double in 40 years.B. Recycling paper helps relieve global climate change.C. Wastepaper can easily break down in landfills.D. There are not enough landfills for wastepaper.5. What makes recycled paper more acceptable?A. The great demand of trees.B. The low processing cost.C. Its dark-color1 ed feature.D. Its improved print performance.6. What does the author propose?A. Punishing the act of cutting trees.B. Recycling paper.C. Improving recycling system.D. Promoting paper industry.7. How is the text mainly developed?A. By analyzing causes and effects.B. By offering research plans and data.C. By discussing problems and solutions.D. By comparing strengths and weaknesses.CA young female athlete in thePhilippinesrecently won many gold medals during a sports meet despite not having proper running shoes. Rhea Ballos, an 11-year-old student ofSalvationElementary Schoolin Balason,Iloilo, wasonly wearing bandages around her feet when she competed at the Iloilo Schools Sports Meet.Facebook user Valenzuela posted pictures of the girl with her feet wrapped in bandages bearing the famous Nike logo. Ballos even wrote the word “NIKE” on the sides of her “shoe” to complete the “Nike running shoes” look. The bandages were tightly wrapped around her feet, creating a thin protective layer against the track. While she was actually barefoot during the races, she was still able to defeat her competitors who all more proper footwear intended for running,According to the post, Ballos bagged the top awards in the 400-meter dash, the 800-meter run, and the 1500-meter run in the girls' categories in the inter school sporting event held in Iloilo, central Philippines.When pictures of her “Nike” footwear become popular, Flipinos on social media praised her. Many noted that instead of falling into self-pity, she was even able to make light of the situation by drawing the Nike logo on her “running shoes”. Some of the commenters of Valenzuela's post expressed how the girl deserved to be recognized by Nike and that the brand should actually give her a new pair of real Nike shoes. Others started getting in touch with the American sports brand, as well as local basketball specialty store Titan 22.It did not take long for Titan co-founder and Alaska Aces head coach Jeffrey Cariaso to take notice of Ballos' outstanding achievement. Cariaso immediately made an effort to get in touch with the young track runner. The seven-time PBA champion has since talked to the student as well as her coaches in an apparent bid to help herout.8. Why did Ballos wear bandages around her feet to compete?A. She couldn't afford to buy shoes.B. She wished to be noticed by Nike.C. She wanted to draw public's attention.D. She thought it fashionable and unique.9. What's people's attitude to Ballos' story?A. Surprised.B. Confused.C. Favorable.D. Doubtful.10. What can we infer from the last paragraph?A. Ballos will be recognized by Nike.B. Ballos will be probably helped by Cariaso.C. Ballos is bound to win more champions.D. Ballos will become a great basketball player.11. Which of the following can best describe Ballos?A. Shy and lucky.B. Kind and brave.C. Clever and outstanding.D. Gifted and optimistic.DThe herd of elephants moving north after leaving the Xishuangbanna National Nature Reserve in Yunnan province has drawn widespread public attention, with tens of millions of people following its movement on TV programs and social media platforms.But this is not because it’s the first time wild Asian Elephants have wandered away from their habitat and headed northward, but for only this time the herd has traveled more than 400 kilometers as far as Kunming. Photographs, videos and stories of the herd’s movement have sparked widespread discussions even overseas.However, there is a need to go behind the “cute photos” and the seemingly “fantastic” event and identify the reasons why wild elephants are leaving their habitat, and find ways to establish harmonious human-animal relationship within habitats and the surrounding forests and human settlements. It is important to scientifically mark the limits of the habitats for elephants and other animals in Xishuangbanna and elsewhere in the country for ecological reasons as well.Planting trees is a key and fundamental step toward restoration of nature. Yet long-term investment and a more scientific approach are needed to maintain the remaining forests as well as to extend the forest cover andstrengthen conservation.Nevertheless, tree cover alone doesn’t mean a suitable habitat for all animals, for different species need different types of vegetation to survive and breed. The elephant herd in Yunnan is a reminder that we have to scientifically conserve the existing forests and turn them into suitable habitats for different species of animals and birds, which will ultimately benefit humans.More ambitious targets should be set to rebuild or improve the food chain, and measures taken to ensure forest resources help wildlife flourish, in order to establish a harmonious human-animal relationship.Forests around the globe are still shrinking, particularly those in tropical and developing countries. The next decade therefore will be extremely important for the world’s forests and wildlife, and China can play a leading role in saving them by better protecting its forests and expanding its forest cover.12. Why has the herd of elephants caused so much public interest?A. There exist heated discussions in the whole country even overseas.B. TV programs and social media platforms want to benefit from them.C. They are the first wild Asian Elephants to leave their natural habitat.D. The elephants has traveled a long distance and lived in harmony with humans.13. What can we infer from the third paragraph about the “fantastic” event?A. More research on the reasons behind the event is required.B. Scientists need to limit the habitats for elephants and other animals.C. People should find ways to have a good relationship with elephants.D. There’s an urgent demand for detailed information about the elephants.14. Which method is provided in the passage to restore nature?A. Expanding the coverage of forest.B. Getting the government’s policy support.C. Bringing up various ways to protect the forests.D. Offering more kinds of vegetation to all animals.15. What does this event of elephants leaving their habitats remind us to do?A. To set more goals to change the food chain.B. To be aware of the situation of the existing forests.C. To realize harmonious coexistence of human and nature.D. To reduce the destruction of the forests around the globe.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。
2021年成都七中高三英语模拟试卷及答案解析

2021年成都七中高三英语模拟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ABird migration is described as the regular, seasonal movement of bird populations from one place to another and back again.The longer days and rich food of the northern summer provide greater chances for birds to feed their young. The longer daylight hours and enormous food resources allow birds to lay larger eggs than those of related non-migratory species that remain in the tropics all year round. As the days shorten in autumn and the breeding period is over, the birds return to warmer regions where the available food supply differs little with the seasons changing. The advantages of migration make up for the high stress, physical exertion(消耗), and other risks of the migration.Day length is the primary environmental factor that encourages birds to prepare for migration. They have an increased appetite which results in weight gaining, giving them the fat reserves that provide energy for their migratory flight. They also show more activity at night, which is when most birds migrate. While the length of day is the primary reason for migration, birds also respond to temperature changes. For example, if a spring is late and the temperature is lower than normal, birds delay migration; if a spring is early, birds also begin migration early.The timing of the migratory cycle must allow birds to arrive on the breeding site so that there is time tobuild a breeding place, mate, lay the eggs, and hatch the young before the rich food is available to feed the young in the nest. Similarly, if birds wait until the climate in their northern breeding grounds becomes tolerable(可忍受的), there will be no time togain the necessary weight that provides the energy needed for their southbound migration.1. Why do birds migrate to the north in spring?A The temperature in the south has risen.B. They like traveling and enjoy the journey.C. The summer there is warmer than that in the south.D. The environment there is more suitable for them to feed their baby birds.2. What are the two factors that cause birds to migrate?A. Day length and food supply.B. Night length and high stress.C. Temperature changes and daylength.D. Food supply and temperature changes.3. Which can be the best title for the text?A. Birds' LifeB. Birds' MigrationC. Birds' Breeding HabitsD. Birds' Living EnvironmentBDo you ever listen to the songs that your parents like? Chances are that you don’t. You probably think the music that they like is old and boring and that the songs on your playlist are muchcooler. But scientists found that people’s music taste changes as time goes by. So it is likely that your own musical preferences will follow a similar path to your parents’, whether you like it or not.We used to think that culture and personality (个性) are the only reasons for different music choices. But researchers at the University of Cambridge noticed that as people enter into different age groups, their social environment changes, and so does their music taste. There are some musical periods that people go through in their life.The first period comes in the teenage years, during which people like strong music such as punk and rock, because teenagers tend to be aggressive or want to be independent.But as people move into early adulthood, their lifestyles change they want to build close relationships with others. As a result, they become fonder of contemporary music, such as pop and R&.B, which is usually uplifting and danceable.When middle age comes, most people have settled down. During this period, people prefer music, such as jazz and classical, as well as music like country, folk and blues.As for old people, they prefer old songs in their childhoods. They generally listen to relaxing music, such as country music and jazz music. But you must be questioning. “Aren’t there old people who are still interested in or even crazy about rock music?” Of course there are. But their reasons for listening to rock music may have changed. At that age people may listen to remind themselves of their youth.4. What do young people usually think of the songs their parents enjoy?A. They are actually less cool.B. They are worth listening to.C. They are especially serious.D. They are hard to understand.5. How many musical periods are there that people go through in their life?A. Two.B. Three.C. Four.D. Five.6. People who want to make friends mostly prefer ________.A. jazz musicB. country musicC. rock musicD. pop music7. What is the best title for the text?A. People Have Different Opinions on MusicB. People Listen to Music for the Same ReasonC. People’s Taste in Music Changes with TimeD. People’s Lifestyle Can Be Changed by MusicCAs I work in theLarkwhistle Garden in Dyer's Bay, Ontario, I take my time and the garden is teaching me about working with the earth. I recognize that there will be both successes and failures and there are many variables(变量)that affect them both.The quality of the seeds planted has a bearing on how the plants will grow. The weather can be too hot, too cold, or exactly right, and usually varies between all three. Weeds seem to grow in the garden and need to be taken care of, pulled, and removed to ensure they do not eat into the fruits, vegetables, and flowers we have so lovingly planted.I take time to stand back and rest, and to observe the plants and how they are growing. Each plant is unique and develops in the way that is best for them. Some have large broad leaves to shadow their fruit from the severe rays of the sun, while other plants are more open, their fruit needing the light to grow and ripen.Getting my hands dirty, feeling the sweat on my forehead, and the strength and flexibility of my body as I dig, bend and work under the warm summer sun, reminds me I am alive in ways I would not have remembered sitting on the couch.It is attractive to move things around, to transplant, and to disturb the natural order of how plants grow. The garden teaches me that it is important to know when to disturb things and when to let them be. The garden's life cycle follows a pattern that is repeated according to laws of nature, birth, growth, and then dies and it teaches us to accept this fact.8. How many variables may affect the growth of plants in the garden?A. Two.B. Three.C. Four.D. Five.9. What can we learn about the author?A. He feels exhausted while gardening.B. He enjoys life from working practice.C. He takes pleasure in harvesting fruits.D. He dreams away his time in the garden.10. How is the garden tended by the author?A. Its rank grass is got rid of.B. Its plants are left to grow freely.C. Its temperature is controlled properly.D. Its plants with large broad leaves are cut off.11. What fact does the author learn from gardening?A. Life takes its course.B. Hard work benefits health.C. Time is short and precious.D. Gardening brings good harvest.DWhat will people die of 100 years from now? If you think that is a simple question,you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine,the human body will last a very long time. Death will come mainly from accidents,murder and war. Today’s leading killers,such as heart disease,cancer,and aging itself,will become distant memories.In discussion of technological changes,the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞)are the basic units of all living things,and until recently,scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells,such as those of brain cells,would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100,medicine will have advanced to the point at which every 10 years or so,people will beable to take medicine to repair their organs(器官). The medicine,made up of the basic building materials of life,will build new brain cells,heart cells,and so on-in much the same way our bodies make new skin cells to take the place of old ones.It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence,but many technical problems still must be cleared up on the way to this wonderful future.12. According to the passage,human death is now mainly caused by ________.A. diseases and agingB. accidents and warC. accidents and agingD. heart disease and war13. In the author’s opinion,today’s most important advance in technology lies in(在于)________.A. the InternetB. medicineC. brain cellsD. human organs14. Humans may live longer in the future because ________.A. heart disease will be far away from usB. human brains can decide the final deathC. the basic materials of cells will last foreverD. human organs can be repaired by new medicine15. How long can humans live in the future according to the passage?A. Over 100 years.B. More than 120 years.C. About 150 years.D. The passage doesn’t tell us.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。

When I was nine years old, I learned how to make a coin disappear. I’d read The Lord of the Rings and ventured into the adult section of the library to search for a book of spells—nine beingthatcuriousageat whichyou’re oldenoughtoworkthroughmorethan1,200pagesoffantasyliteraturebut young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand technique, and I dedicated the next months topractice.At first the magic wasn’t any good. At first it wasn’t even magic; it was just a trick—a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over andover,athousandtimes inaday,andaftertwoweeks ofthismymomgotacarpetfromthehardwarestoreand placed it under the mirror to mufflethe sound of the coin falling again andagain.I had heard my dad work through passages of new music on the piano, so I knew how to practice—slowly, deliberately,goingforprecisionratherthanspeed.OnedayItriedthe illusioninthemirrorandthe coinvanished. It did not look like a magic trick. It looked like amiracle.One of the lessons you learn very early on as a magician is that the most amazing part of a trick has nothing to do with the secret. The secret is simple and often dull: a hidden piece of tape, a small mirror, a duplicate playing card, diversion of the audience’s attention. In this case, the secret was a series of covert ( 暗中的) technique to hide the coin behind my hand in the act of opening it, a dance of the fingers that I learned so completelyI didn’t evenhavetothink. I wouldclosemyhand, thenopenit, andthecoinwouldvanishnotbyskill but by realmagic.4.What book did the author intend to find in the library when he was nine yearsold?A.A book teaching people how to make a coindisappear.B.The second book of The Lord of theRings.C.A book on how to become amagician.2D.A book of realmagic.5.The underlined word “muffle”probably means ____ _.A.cleanB.punishC.lowerD.kill6.What did the author learn from his dad playing thepiano?A.

No pains, nogains.7.Which of the following is not mentioned as a magiciantrick?A.Carrying out skillful handmoves.ing real magic to createmiracles.C.Hiding some stage tools inside thecoat.D.Guiding the audience to focus on somethingunimportant.CDolphins are universally regarded as some of the cleverest creatures in the world. In captivity( 圈养), they can be trained to complete complex tasks such as jumping through hoops and somersaulting through the air.But their intelligence doesn’t stop there. In a recent study of cetaceans (鲸目动物)--a groupof animals that includes dolphins and whales--researchers created a list of intelligent behaviorsobserved in 90 different cetacean species, reported the Guardian. For example, the smartest cetaceans hunt in groups, share knowledge through mimicry (模仿) and even care for eachother's children. Some even consider their behavior to be human-like.“There is the saying that ‘it takes a village to raise a child’ seems to be true for both whales and humans,”Michael Muthukrishna of the London School of Economics, co-author of the study, told the Guardian.However,cetaceans don’t justusetheir brainpowerforsurvival.The studysuggeststhatdolphinsmighteven gossip. That's because some species greet each other withspecific whistles, just as humans greet each other by name, the Guardian reported. Sometimes, agroup of dolphins whistles the “name” of a dolphin that isn't there. Could they be speaking abouttheir “friend” behind itsback?For the researchers, dolphin small talk is a big deal. As they found that the most social cetaceans also have the largest brains, they argue that cetacean intelligence developed to meet thedemands of complex social groups.Knownasthe “cultural brainhypothesis (假设),” ithadonly beenusedtoexplaintheintelligenceofhumans andother primates (灵长目动物). Thenewstudyaimedtofindacommonpathwayfortheevolutionof intelligence among biologically3differentspecies.“It is interesting to think that whale and human brains are different in their structure but have brought us to the same patterns in behavior, ” Luke Rendell, a biologist at the University of St Andrews, told the Guardian.Indeed,westillhavealottolearnaboutourintelligentocean-dwellingneighbors.“Wedon’thavetolo okat other planets to look for aliens,” Muthukrishna told the Guardian, “because we know that underwater there are these amazing species with so many parallels to us in their complex behaviors.”8.The recent study was intended to ____.A.learn more about intelligent creatures of theseaB.explain the intelligence of humans andcetaceansC.create a list of intelligent behaviors of different cetaceanspeciesD.see whether the intelligence of different species evolved in the sameway9.The implied meaning of the underlined part in Paragraph 3isthat ____ _.A.villagers have the responsibility to raise any child in thevillageB.like human beings, whales even help raise each other’s babiesC.cetaceans have social behaviors very similarto human beingsD.it is not easy for one villager to take care of his or her ownchild10.Itcanbe inferredfromthe passagethat____ .A.it is unnecessary to look for aliens and do research intothemB.some cetaceans have the same intelligence as humanbeingsC.both dolphins and whales greet each other with specificwhistlesD.both dolphins and whales have a lot in common with humans inbehaviors11.What is the best title for thispassage?A.

Since ancient times, medics have relied on their sense of smelltohelpthemworkoutwhatiswrongwiththeirpatients. Fruityodors (气味) onthebreath, forexample, let themmonitortheconditionofdiabetics (糖尿病病人).But doctors can, as it were, smell only what they can smell—and many compounds characteristic of disease are odorless. To deal with this limitation, Hossam Haick, a chemical4engineer at the Technion Israel Institute of Technology in Haifa, has developed a device which, he claims, can do work that the human nose cannot.The idea behind Dr. Haick’s invention is not new. Many diagnostic “breathalysers” already exist, and sniffer dogs,too,canbe trainedtodetectillnessessuchascancer.Mostofthese approaches,though,are disease-specific. Dr. Haick wanted to generalize theprocess.As he describes in ACS Nano, he and his colleagues created a series of electrodes made of carbon nanotubes (纳米碳管).

Whenafilmreacted, itselectricalresistancechanged in a predictable manner. The combined changes produced an electrical fingerprint that would be diagnostic of the disease a patient was sufferingfrom.To test their invention, Dr. Haick and his colleagues collected 2,808 breath samples from 1,404 patients who were suffering from at least one of the diseases. Its success varied. It could distinguish between samples from patientssufferingfromgastriccancerandbladdercancer only64%ofthetime. Atdistinguishinglungcancerfrom head and neck cancer it was, though, 100% successful. Overall, it got things right 86% of the time. Not perfect, but a useful aid to a doctor planning to conduct further investigations. And this is only the first model.

2021年成都七中高三英语模拟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AWhat to Eat—and What to Skip—When It Comes to Takeout FoodIf the burden on your wallet doesn't bother you much, the effect your takeout habit can have on your waistline just might arouse your attention. Here's the best and worst of the lot for your belly.Steamed Vegetable Dumplings: Order This.When she orders Chinese, registered dietitian nutritionist Elisa Zied gets an order of steamed vegetable dumplings. "I often pair them with either chicken and broccoli in brown sauce(I ask for a little saucemade without sugar)or steamed shrimp dumplings," she tells us.Crab Wontons: Not That!When you deconstruct crab wontons, it's easy to see why they're a "Not That!" The inside is filled with crabmeat and cream cheese(which is just a fancy, spreadable fat).The wonton is made of refined flour, egg and salt and the crispy(脆的)coating is a result of a deep oil bath.Peking Duck: Order This.Most of the fat from the skin flows out of the duck over the course of cooking, making this a healthier choice than most of the stir-fry dishes available. Order a side of steamed vegetables and serve it with a small scoop of brown rice. Done and done!Sweet and Sour Anything: Not That!Anything with “sweet and sour” in its title is a powerful cue that something has been deep-fried and covered in a sickly-sweet pink sauce. If you pair your selection with a side of rice, you're looking at a 1,000-calorie meal.Summer Roll: Order This.Summer rolls are steamed instead of fried—and typically filled with lean proteins and vegetables, making them a winning appetizer in our book. Pair them with an order of edamame(毛豆)and a broth-based soup for a satisfying, filling meal.Spring Roll: Not That!Spring=deep-fried, which is why we say to skip them! They're filled with fat and calories your belly doesn't need.1.What kind of cooking method should be skipped according to the text?A.Steaming.B.Stir-frying.C.Deep-frying.D.Boiling.2.Which of the following suits as a good starter for a meal?A.Chicken and broccoli.B.Steamed vegetable dumplings.C.Peking duck.D.Summer rolls.3.Where can the text be found?A.In a recipe.B.In a guidebook.C.In a science fiction.D.In a health magazine.BThe early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes,and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece ofplastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.4. Why do baby turtles move to the sea at night?A. They dislike sunshine.B. They prefer lower temperatures.C. They can find food easily then.D. They need to avoid enemies.5. What does the author think of the young turtles in Paragraph 3?A. Pitiful.B. Careless.C. Interesting.D. Courageous.6. What can we learn about sea turtles?A. They mainly feed on fish and meat.B. They always produce eggs at their birthplaces.C. They can live for around forty years.D. They visit their beach homes several times a year.7. What is the text mainly about?A. The homes of green sea turtles.B. How sea turtles find their food.C. The dangers faced by sea turtles.D. How young turtles become adults.COn the night of September 19, 1961, Betty Hill and her husband Barney were driving home through the White Mountains from Niagara Falls. They were travelling on anearly deserted two-lane highway when Betty noticed a steady light in the sky that was getting bigger and brighter.She thought it was a planet or a star. Barney, stimulated at her excitement, said it was probably just a wandering aeroplane. Whatever it was, it appeared to be following them.They stopped their car for a closer look. What they said happened next, changed their lives. The flying object was noiseless. It appeared to be spinning. It was as big as a jet but shaped like a pancake.So formed the tale of Betty Hill, a New Hampshire social worker who, with Barney, a postal worker, claimed to be kidnapped by aliens, who were from outer space, on a moonlit night about 60 years ago.After reluctantly going public with her experience, Hill, who died of cancer at her New Hampshire home, aged 85, became a celebrity on the UFO circuit and was known as the “first lady of UFOs”.Intriguingly, at the time of the incident, the Hills remembered nothing except that they had spied a strange object in the sky. Later, troubled by nightmares and other stress-related pains, the couple underwenthypnosis(催眠) where the full story came out with the aid of Boston psychiatrist Benjamin Simon, an expert in medical hypnosis.On their night of contact the Hills arrived homeat 5 a.m., unable to account for two lost hours. They were also confused by the odd marks on their telescopes, deep signs on the tops of Barney’s best shoes, Betty’s torn dress and strange circular markings on their car that made the needle of a compass jump wildly.After seeing them for six months, the psychiatrist concluded the Hills’ lost memory about the hours they lost on that night in 1961 “appeared to involve an amazing experience on the part of both of the Hills”. Whether the experience had been fantasy or reality, Simon could not say, but he said he was convinced they had not been lying. He guessed that it had been a kind of shared dream.Reports of aliens capturing humans and taking them aboard oddly shaped spacecraft were “comparatively rare” before 1975. After a movie, “The UFO Incident”, about the Hills came out, however, such stories increased.8. When they saw the strange object in the sky, Barney and Betty Hill ______________.A. were astonished at its strange flight and noiseB. regarded it as just a wandering car following themC. realized immediately what the danger it might causeD. showed curiosity in discovering what it really was9. The word “Intriguingly” in paragraph 6 most probably means “______________”.A. RidiculouslyB. TemporarilyC. RemarkablyD. Mysteriously10. The Hills later sought the help of a psychiatrist because ______________.A. they had lots of secrets in their lives after the strange experienceB. their lives were greatly disturbed by the unexpected experienceC. they wanted to share their unforgettable experience with the expertD. they hoped to forget completely what had happened to them11. This article was written in order to ______________.A. describe an unusual event to the readersB. convince readers of the existence of UFOsC. record how people were caught by aliensD. warn people of the dangers the UFOs causeDA satellite is about to demonstrate a new way of capturing space junk with magnets for the first time. With the frequency of space launches dramatically increasing in recent years, the potential for a disastrous collision above Earth is continually growing. Now, Japanese orbital clean-up company Astroscale is testing a potential solution.The firm's End-of-Life Services by Astroscale demonstration mission is scheduled to lift off on 20 Marchaboard a Russian Soyuz rocket. It consists of two spacecraft: a smal “client” satellite and a larger “servicer” satellite, or “chaser”. The smaller satellite is equipped with a magnetic (磁力的) plate which allows the chaser todock withit.The two stacked spacecraft will perform three tests once in orbit, each of which will involve the servicer satellite releasing and then recapturing the client satellite. The first test will be the simplest, with the client satellite drifting a short distance away and then being recaptured. In the second test, the servicer satellite will set the client satellite tumbling before catching up with it and matching its motion to grab it.Finally, if those two tests go well, the chaser will live up to its name by letting the client satellite float a few hundred metres away before finding it and attaching to it. All of these tests will be performed autonomously, with little to no human input once they are set in motion.“These kinds of demonstrations have never been done before in space - they are very different to, say, an astronaut controlling a robotic arm on the International Space Station,” says Jason Forshaw at AstroscaleUK.“This is more of an autonomous mission.” At the end of the tests, both spacecraft will burn up in Earth's atmosphere.If companies wanted to use this capability, they would have to attach a magnetic plate to their satellites so they could be captured later. Because of the growing space garbage problem, many countries now require firms to have a way to bring back their satellites once they run out of fuel or fail, so this could be a fairly simple likely plan, Forshaw says. Right now, each chaser can only nab one satellite, but Astroscale is working on a version that could drag three or four out of orbit at once.12. Which of the following can replace the underlined word "dock with" in Paragraph 2?A. Deal with.B. Keep up with.C. Join together.D. Crash.13. Why many countries now require firms to have a way to bring back their satellites?A. Because of the growing space waste problem.B. Because the frequency of space launches are dramatically increasing.C. Because they can earn large profits from it.D. Because Astroscale has found a new method of capturing the space garbage.14. What will Astroscale do to solve the space junk problem?A. An astronaut controls a robotic arm on the International Space to capture the “client” satellite.B. Through a magnetic plate remotely controlled by humans on the ground to catch the “client” satellite.C. Finding the "client "satellite and attaching to it with a magnetic plate automatically.D. Tumbling to match the motion of “client satellite the drag three or four satellites out of its orbit into atmosphere.15. What can we infer from the passage?A. People will bum the space junk up in Earth's atmosphere in the future.B. Japan andRussiawill conduct space debris cleanup experiment together.C. These kinds of demonstrations have never been done before.D. The demonstration mission will be divided into three phases.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。

2021届成都市第七中学高三英语一模试卷及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项ANothing beats live music, but the venue makes a difference. When you're able to score tickets to an incredible concert in an incredible place, you won't forget the experience. Here are some of the coolest music venues from around the world. If you haven't been to any of these, you've got some traveling to do.Red Rocks, Morrison, the United StatesRed Rocks might be the most beautiful and famous venue in the United States. At 6,450 feet above sea level, Red Rocks is a geologically formed natural stage. Its massive sandstone provides a perfect stage for jam bands. If you're into the blues and jazz, you'll have no trouble finding something in line with your interests.Meet Factory, Prague, Czech RepublicSmallest venues on this list, Meet Factory is an art gallery, theater, and music venue. The venue only accommodates 1,000 people, so you won't see any huge names come through. Still, it's a great place to see up-and-coming local acts, and if you've got an eye for contemporary art, you'll love your time here.Arena of NÎmes, NÎmes, FranceOriginally built around A. D. 70, the Arena of Nimes presents concertgoers with an interesting question: Should they enjoy the music, or marvel at the architecture? The Arena is, after all, one of the world's best-preserved Roman theaters. Many major touring acts plan stops at the Arena of Nimes, especially during the venue's annual festival.Sydney Opera House, Sydney, AustraliaThe Sydney Opera House is one of the world's most famous performing venues. I's also one of the most distinctive buildings in Sydney, thanks to the breathtaking design by Danish architect Utzon. It hosts about 40 events per week, so whether you're into jazz, rock, classical music, or opera, you'll find something to watch.1.Where can you enjoy music in natural beauty?A.At Red Rocks.B.At Meet Factory.C.At Arena of Nimes.D.At Sydney Opera House.2.What is special about Meet Factory?A.It enjoys breathtaking scenery.B.It hosts both musical and artistic events.C.It is the largest venue of all.D.It is famous for contemporary music.3.What do the listed music venues have in common?A.They have a long history.B.They are built near the sea.C.They accommodate thousands of people.D.They are beautiful tourist attractions.BThree years ago, a group of researchers at Cornell University Food and Brand Lab had a guess. They knew that many apples being served to kids as part of the National School Lunch Program were ending up in the trash, almost untouched. But unlike others, they wondered if the reason was more complicated than simply that the kids didn’t want the fruit.They thought the fact that the apples were being whole, rather than sliced (切片的), was doing the fruit no favor. And they wanted to prove this idea.They carried out a study at eight schools and found that fruit consumption (消费) jumped by more than 60 percent when apples were served sliced. They then made a follow-up study at six other schools, which not only showed the same result, but further supported. The whole apple consumption at schools that served sliced apples reduced by about 50 percent than before.Based on these results, it seems that even the simplest forms of inconvenience can influence us. Sliced apples just make more sense for kids. The hardest part is getting kids to start eating fruit, and that’s exactly why sliced apples are the way to go. A child holding a whole apple has to break the skin, eat around the core (果核), and deal with the inconvenience of holding a large fruit. These problems might seem silly or unimportant, but they’re important when you’re missing teeth or have braces (牙箍), as so many kids do.Sometimes what seems like a really small inconvenience actually makes a huge difference.4. What can we learn from Paragraph 1?A. Lots of apples served to kids were wasted.B. Researcher supported the lunch program.C. Apples are not the only acceptable fruit for kids.D. The lunch program was well worth spreading.5. What did researchers want to prove?A. Kid didn’t want the fruits.B. Kids favored the whole apples.C. Kids preferred to the sliced apples.D. Kid’s eating habits influenced fruit consumption.6. According to the study, we can know________.A. 14 schools served sliced fruitsB. kids have problems eating the whole applesC. eating fruits must be healthy for childrenD. few kids are missing teeth or have braces7. What’s the main idea of the passage?A. Form matters more than taste.B. Apples are beneficial to each kid.C. The way fruit is eaten links kids’ growth.D. Inconvenience probably makes a difference.CWhen Rich Jean wanted to help his daughter, Abigail, learn to read, he took her to the library near their home in Brooklyn, N. Y. That's where they met Hasina Islam, who Jean says arose her interest in reading and the library.“You see what you started? You see that spark that you put in this child?” Jean told Hasina Islam at aStoryCorpsconversation in 2016. At the time, Abigail was 7 and Islam was 27. Their friendship began when Abigail was 3. Through the years, Islam has offered book suggestions that Abigail has read with great enthusiasm. “What's cool is that Hasina has recommended a lot of books that I, at the time, thought might be a little too advanced for you," Jean told Abigail. “Like Charlie and the Chocolate Factory." Abigail said.Islam's own love of the library was sparked when she was in the third grade. She lived near the main branch of the Queens Public Library in New York City, and she went there to research Henry Hudson, an English explorer, for a school project."The librarian made me feel so special. She remembered my name, and my favorite thing was that she gave me book recommendations," she said." When I was graduating from college, I thought about how I was going to make a difference in the world. And I remembered my librarian,and I remembered that feeling that she gave me every single time I went to the library. ”8. When might Abigail and Hasina Islam first meet?A. In 2012.B. In 2016.C. In 2018.D. In 2020.9. What do we know about Charlie and the Chocolate Factory from the text?A. It was Islam's favorite book.B. It might be hard for Abigail.C. It was a best seller at that time.D. It was important for Abigail.10. How did Hasina Islam help Abigail?A. By offering books to her.B. By reading together with her.C. By giving advice on books.D. By introducing great libraries.11. What is paragraph 3 mainly about?A. Islam's special college life.B. Islam's working experiences.C Islam's living conditions. D. Islam's reasons for loving library.DSome of my earliest memories involve sitting with my dad in his study every evening when he came home from the office. I’d watch as he put his personal items away: his watch, wallet, comb and car keys would always occupy the same spot on the table every time.Dad’s comb was bought when he married Mum. Every evening, he would smile, hand me the comb and say: “Be a good girl and help Daddy clean it, OK?” I was more than happy to do it. This seems amundanetask, but it brought me such joy at that time. I would excitedly turn the tap on, then brush the comb with a used toothbrush as hard as I could. Satisfied that I’d done a good job, I would proudly return the comb to Dad. He would smile at me, and place the comb on top of his wallet.About two years later, Dad started his own business. I started primary school. That was when things started to change. Dad’s business wasn’t doing so well, and he didn’t come home as much as he used to. Over the years, I stopped waiting for him to come home.Today, I’ve graduated from college and Dad’s business are better now. Yet the uncomfortable silence between Dad and me continued. Two days before my birthday last year, Dad came home early and said to me, “Hey, would you like to help me clean my comb?” I looked at him a while, then took the comb and headed to the sink. It’s a new comb. I hadn’t noticed that he’d changed it. I brushed the comb, and it hit me then: why, as a child, helping my dad clean his comb was such a joy.I passed the clean comb back to Dad. This time, I noticed my day has aged. But his smile is still as heartwarming as before. Dad carefully places his comb on top of his wallet. After so many years, I guess some things never change. And for that, I’m glad.12. As a child, the author helped her dad clean his comb happily because ________.A. she was good at cleaning the combB. she thought that she should do that as a good girlC. her dad was home early to spend the evening with herD. the comb was important for her father and her mother13. Which of the following words can best replace the underlined wordmundanein paragraph two?A. importantB. excitingC. unnecessaryD. uninteresting14. When the author said, “It’s a new comb.

2021年成都七中高三英语模拟试卷及参考答案第一部分阅读(共两节,满分40分)第一节(共15小题;每小题2分,满分30分)阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项AWhen the weather is bad or when the flu breaks out, we can let the kids do some fun things at home, which can be beneficial to kids.Reading out loudIf your children are young enough, don't forget to read books to them out loud! Few children dislikehaving a good book read to them, and it's great for the development of their brains. However, if your children are a bit older and have moved onto more advanced books, there is always the choice of listening to an audiobook. This can also be done while they're doing something else.Playing board gamesMaybe your children's table is full of board games, which have been forgotten for a long time. It's a good time to bring them out when playing outside is no longer a choice. Surely, playing board games is a great way to connect with children. In addition, many board games are designed to get children thinking!Having a dance partyConsidering that all you need is a speaker or maybe just a phone, you can have a dance party wherever you are! This is a great way to get kids’ bodies moving when they are inside. Play some of your children's favorite music and let them dance to it. Not only is it good exercise, but it will help your children feel time is flying!Doing jigsaw (拼图) puzzlesFor most people that have children, it's common to have at least one jigsaw puzzle at home. Jigsaw puzzles are great because everyone can do them on their own time. Besides, your whole family will have a sense of achievement when everyone is smiling over the finished product.1. What do reading out loud and playing board games have in common?A. They both develop children's team spirit.B. They both improve children's listening ability.C. They both do good to children's thinking ability.D. They both focus on interaction between children.2. Which of the following combines exercise and music?A. Reading out loud.B. Playing board games.C. Doing jigsaw puzzles.D. Having a dance party.3. What is the purpose of the text?A. To list four interesting children's parties.B. To recommend four children's favorite books.C. To introduce some activities for children inside.D. To show some funny things for children outside.BWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tiny pieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.4. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.5. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.6. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.7. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingCIt was five years ago that something unforgettable happened. My wife and I celebrated our 40thwedding anniversary that year. It was a lovely event hosted by our sons for us. My wonderful friends from the past surprised us with gifts and congratulations. Our gift to each other was a driving trip out west. We drove fromOntariointoAlberta, then southward intoGlacierNational ParkinMontana, and continued toYellowstoneNational Park.It was a cold spring day, and theBeartooth Highwayhad opened for the season just days before. Alongside the road, there was still a great amount of snow there. The scenery was so impressive that we made lots of stops to record memories with my camera. At the highest point of the highway, I stopped at a lookout to catch the amazing views, with my wife in the centre of my camera lens.There were not many cars on the road. Sometimes, cars with energetic young tourists passed by. And then we heard a motorcycle in the distance. The driver of the motorcycle, who wore dirty clothes, parked behind our cars. As he approached us, his only words were, “Give me your camera and get over there with your wife.” I must admit I felt nervous that we might be robbed where we just created some beautiful memories. Surprisingly, he just took a picture of us, handed back my camera and rode off before we could express our gratitude. The photo he took is one of the most valuable and prized of our trip.I learned my lesson somewhere I least expected it. We should never judge a man by his appearance. If themotorcycle driver reads this story and remembers the situation, we would like to say “Thank you” to him.8. According to the passage, what do we know about the trip?A. It was taken by train to the west.B. It was a suggestion from their friends.C. It was in the late autumn five years ago.D. It was a gift for their wedding anniversary.9. Why was the author nervous when the motorcycle driver offered to take a picture?A. He could have lost the camera.B. His wife might not be satisfied with the view there.C. The motorcycle driver would borrow the camera.D. The motorcycle driver might not be good at the taking pictures.10. Which of the following best describes the driver of the motorcycle?A. Kind and straightforward.B. Rich and generous.C. Creative and capable.D. Careful and admirable.11. Which of the following can be concluded from the passage?A. No pains, no gains.B. Seeing is believing.C. Don’t judge a book by its cover.D. The longest journey begins with the first step.DA team of researchersfrom theUniversityofColorado Boulderhave created a revolutionary type of robotic muscles. They are strong and flexible at the same time, can feel the movements they perform and, whenever they suffer damage, they can self-heal. However, what is best about them is probably the fact that they are extremely cheap to manufacture.The robotic muscles have been called actuators, and have drawn inspiration from real-life muscles. By creating robots equipped with this kind of actuators, researchers would allowthem to perform movements just like human muscles.To make the robotic muscles work, they filled some flexible material with electrodes(电极)and with liquid and oil. Then, they applied some electricity, and the liquid and oil started moving around the electrodes and powered them. This way, the robotic muscles started contracting and relaxing just like real muscles, but a lotquicker.Researchers also took inspiration from the variety of human muscles, and created more types of actuators, each of them performing a different movement. They called these robotic muscles HASEL ( Hydraulically-Amplified Self-healing Electrostatic). However, they are superior to biological muscles as they are stronger, faster, and more flexible.Even the researchers were amazed they could develop such technology. Eric Acome, the author of one of the studies, explained what is unique about the robotic muscles.“The ability to create electrically powered soft actuators that lift a gallon of water at several times per second is something we haven't seen before.”These muscles are special because they are also self-healing. This property is given by the liquid placed inside of them, which also gives them a lot more advantages than those mechanisms (机械)using solids. In the end, the material which keeps the liquid, the oil and the electrodes is extremely cheap. It is a type of polymer (聚合物)similar to the one used for potato chips bags, and can be manufactures for only 10 cents.12. What can we learn about actuators?A. They can heal on their own.B. They are biological muscles.C. They can not move like human muscles.D. They are slower to react than real muscles.13. What do actuators use to directly power electrodes?A. Solids.B. Liquid and oil.C. A type of polymer.D. Potato chips bags.14. What is the last paragraph mainly about?A. The origin of actuators.B. The opinions on actuators.C. The advantages of actuators.D. The significance of actuators.15. In which part of a newspaper will the textmost probably appear?A. Health.B. Culture.C. Education.D. Technology.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。

When I was nine years old, I learned how to make a coin disappear. I’d read The Lord of the Rings and ventured into the adult section of the library to search for a book of spells—nine being that curious age at which you’re old enough to work through more than 1,200 pages of fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found instead taught basic sleight-of-hand technique, and I dedicated the next months to practice.At first the magic wasn’t any good. At first it wasn’t even magic; it was just a trick—a bad trick. I spent hours each day in the bathroom running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks of this my mom got a carpet from the hardware store and placed it under the mirror to muffle the sound of the coin falling again and again.I had heard my dad work through passages of new music on the piano, so I knew how to practice—slowly, deliberately, going for precision rather than speed. One day I tried the illusion in the mirror and the coin vanished. It did not look like a magic trick. It looked like a m iracle.One of the lessons you learn very early on as a magician is that the most amazing part of a trick has nothing to do with the secret. The secret is simple and often dull: a hidden piece of tape, a small mirror, a duplicate playing card, diversion of the audience’s attention. In this case, the secret was a series of covert ( 暗中的 ) technique to hide the coin behind my hand in the act of opening it, a dance of the fingers that I learned so completely I didn’t even have to think. I would close my hand, then open it, and the coin would vanish not by skill but by real magic.24.What book did the author intend to find in the library when he was nine years old?A.A book teaching people how to make a coin disappear.B.The second book of The Lord of the Rings.C.A book on how to become a magician.D.A book of real magic.25.The underlined word “muffle” probably means____ _ .A. cleanB. punishC. lowerD. kill26.What did the author learn from his dad playing the piano?A. Without music, life is of no value.B. Practice makes perfect.C. Great liars are also great magicians.D. No pains, no gains.27.Which of the following is not mentioned as a magician trick?A.Carrying out skillful hand moves.ing real magic to create miracles.C.Hiding some stage tools inside the coat.D.Guiding the audience to focus on something unimportant.CDolphins are universally regarded as some of the cleverest creatures in the world. In captivity ( 圈养), they can be trained to complete complex tasks such as jumping through hoops and somersaulting through the air.But their intelligence doesn’t stop there. In a recent study of cetaceans (鲸目动物)--a group of animals that includes dolphins and whales--researchers created a list of intelligent behaviors observed in 90 different cetacean species, reported the Guardian. For example, the smartest cetaceans hunt in groups, share knowledge through mimicry (模仿) and even care for each other's children. Some even consider their behavior to be human-like.“There is the saying that ‘it takes a village to raise a child’ seems to be true for both whales and humans,”Michael Muthukrishna of the London School of Economics, co-author of the study, told the Guardian.However, cetaceans don’t just use their brain power for survival. The study suggests that dolphins might even gossip. That's because some species greet each other with specific whistles, just as humans greet each other by name, the Guardian reported. Sometimes, a group of dolphins whistles the “name” of a dolphin that isn't there. Could they be speaking about their “friend” behind its back?For the researchers, dolphin small talk is a big deal. As they found that the most social cetaceans also have the largest brains, they argue that cetacean intelligence developed to meet the demands of complex social groups.Known as the “cultural brain hypothesis (假设),” it had only been used to explain the intelligence of humans and other primates (灵长目动物). The new study aimed to find a common pathway for the evolution of intelligence among biologically different species.“It is interesting to think that whale and human brains are different in their structure but have brought us to the same patterns in behavior, ” Luke Rendell, a biologist at the University of St Andrews, told the Guardian.Indeed, we still have a lot to learn about our intelligent ocean-dwelling neighbors. “We don’ t have to look at other planets to look for aliens,” Muthukrishna told the Guardian, “because we know that underwater there are these amazing species with so many parallels to us in their complex b ehaviors.”28.The recent study was intended to ____ .A.learn more about intelligent creatures of the seaB.explain the intelligence of humans and cetaceansC.create a list of intelligent behaviors of different cetacean speciesD.see whether the intelligence of different species evolved in the same way29.The implied meaning of the underlined part in Paragraph 3 i s that ____ _ .A.villagers have the responsibility to raise any child in the villageB.like human beings, whales even help raise each o ther’s babiesC.cetaceans have social behaviors very similar to human beingsD.it is not easy for one villager to take care of his or her own child30.It can be inferred from the passage that ____ .A.it is unnecessary to look for aliens and do research into themB.some cetaceans have the same intelligence as human beingsC.both dolphins and whales greet each other with specific w histlesD.both dolphins and whales have a lot in common with humans in behaviors31.What is the best title for this passage?A. Aliens living underwaterB. A study of intelligent dolphinsC. Intelligent creatures of the seaD. Reasons for the intelligence of sea c reaturesDOne of a doctors’ most valuable tools is his nose. Since ancient times, medics have relied on their sense of smell to help them work out what is wrong with their patients. Fruity odors (气味) on the breath, for example, let them monitor the condition of diabetics (糖尿病病人).But doctors can, as it were, smell only what they can smell—and many compounds characteristic of disease are odorless. To deal with this limitation, Hossam Haick, a chemical engineer at the Technion Israel Institute of Technology in Haifa, has developed a device which, he claims, can do work that the human nose cannot.The idea behind Dr. Haick’s invention is not new. Many diagnostic “breathalysers” already exist, and sniffer dogs, too, can be trained to detect illnesses such as cancer. Most of these approaches, though, are disease-specific. Dr. Haick wanted to generalize the p rocess.As he describes in ACS Nano, he and his colleagues created a series of electrodes made of carbon nanotubes (纳米碳管). Each of these had one of 20 organic films laid over it. Each film was sensitive to one of a score of compounds known to be found on the breath of patients suffering from a range of 17 illnesses, including Parkinson’s disease, multiple sclerosis, and bladder cancer. When a film reacted, its electrical resistance changed in a predictable manner. The combined changes produced an electrical fingerprint that would be diagnostic of the disease a patient was suffering from.To test their invention, Dr. Haick and his colleagues collected 2,808 breath samples from 1,404 patients who were suffering from at least one of the diseases. Its success varied. It could distinguish between samples from patients suffering from gastric cancer and bladder cancer only 64% of the time. At distinguishing lung cancer from head and neck cancer it was, though, 100% successful. Overall, it got things right 86% of the time. Not perfect, but a useful aid to a doctor planning to conduct further investigations. And this is only the first model. Slightly adjusted, its success rate would be expected to improve.32.How useful is nose to doctors?A.They can smell what o ther people can’t.B.They could tell which diseases are odorless.C.They diagnose illness through their sense of smell.D.They will apply new device to helping with diagnosing illness.33.What is the most special aspect of the new invention?A.It can help detect more than one disease.B.It is made of a series of electrodes.C.It works through analyzing patients’ electrical f ingerprints.D.It can be used to help diagnose cancers.34.What can we i nfer about the device?A.It’s the first invention by using principle of sense of smell.B.It will be a useful tool in diagnosing lung cancer.C.Its success rate differs from patient to patient.D.It can successfully tell Bladder cancer from other cancers.35.What is the best title for this passage?A. High Tech in d iagnosing illnessB. A new way in diagnosing illnessC. Diagnosing illness can be easyD. Diagnosing illness by smell第二节(共5 小题;每小题2 分,满分10 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,选项中有两项为多余选项。
