4. Who was the first scientist? There is, of course, no answer to this question. It is probably more fruitful to ask, "What type of man gave the first scientific explanation to natural phenomena(现 现 象 )?" We cannot completely answer this question, either, but there can be little doubt that he was a man who was curious about his environment, and who attempted to explain his observations without reference to a supernatural being. We say this because supernatural explanations of natural phenomena can never be scientific.

【真题例析】(2016·全国卷Ⅰ,阅读理解D)The meaning of silence varies among cultural groups. Silences may be thoughtful,or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness,uneasiness,or worry. Silence may be viewed by some cultural groups asextremely uncomfortable;therefore attempts may be made to fill every gap(间隙) with conversation.Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.Many Native Americans value silence and feel it is a basic part of communicating among people,just as some traditional Chinese and Thai persons do. Therefore,when a person from one of these cultures is speaking and suddenly stops,what may be implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures,silence is a call for reflection.Other cultures may use silence in other ways,particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example,Russian,French,and Spanish persons may use silence to show agreement between parties about the topic under discussion. However,Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her.In still another use,persons in Asian cultures may view silence as a sign of respect,particularly to an elder or a person in authority.Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily.A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.35.What may be the best title for the text?A.Sound and SilenceB.What It Means to Be SilentC.Silence to Native AmericansD.Speech Is Silver;Silence Is Gold二、文章大意题每一篇文章都有其大意,获取大意的方法是找主题句。

1.The main idea of the passage is that __________.2.The passage is mainly about __________.3.The best title of the passage is __________.4.From the passage we can learn/ conclude that __________.5.The topic/ subject discussed in the passage is __________.6.Which is the best title of this passage?7.What’s the main idea of the passage?8.What’s the purpose of__________?实战演练A(全国I)Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.1. What is the text mainly about?A. Hoatzins in dry and rainy seasons.B. The relatives and enemies of hoatzins.C. Primitive birds and hoatzins of the Amazon.D. The appearance and living habits of hoatzins.2. Young hoatzins are different from their parents in that_________ .A. they look like young cuckoosB. they have claws on the wingsC. they eat a lot like a cowD. they live on river banks3. What can we infer about primitive birds from the text?A. They had claws to help them climb.B. They could fly long distances.C. They had four wings like hoatzins.D. They had a head with long feathers on the top.4. Why do hoatzins collect together in smaller groups when the rainy season comes?A. To find more food.B. To protect themselves better.C. To keep themselves warm.D. To produce their young.B(全国卷I )Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best .Those testedwith their animal friends had smaller change in blood pressure and returned. Most quickly to baseline heart rates .With pets in the room, people also made fewer math mistakes. Than when doing in front of other companions. It seems people feel more released (放松)around Pets, says Allen, who thinks it may be because pets don’t judge.A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a Year studying 36 fat people and were put on a diet-and-exercise programs; a separate group of 56 fat people without pets were put on a diet program. On average,people lost about 11 pounds,Or 5% of their body weight .Their dogs did even better,losing an average of 12 pounds,more then 15%of their body weight .Dog owners didn’t lose any more weight than those without dogs but ,say Researchers,got more exercise overall –mostly with their dogs –and found it worth doing.1.What does the text mainly discuss?A. What pets bring to their ownersB. How pets help people calm downC. people’s opinions of keeping petsD. Pet’s value in medical research2.We learn from the text that a person with heart disease has a better chance of getting well if____________A. he has a pet companionB. he has less stress of workC. he often dose mental arithmeticD. he is taken care of by his family3.According to Allen, why did the people do better with pets around when facing stressful tasks?A. They have lower blood pressure.B. They become more patient.C. They are less nervous.D. They are in higher spirits.4.The research mentioned in the last paragraph reports that __________.A. people with dogs did more exerciseB. dogs lost the same weight as people didC. dogs liked exercise much more than people didD. people without dogs found the program unhelpfulC(天津)To err is human. To blame the other guy is even more human.Common sense is not all that common.Why tell the truth when you can come up with a good excuse?These three popular misquotes(戏谑的引语)are meant to be jokes, and yet they tell us a lot about human nature .To err, or to make mistakes, is indeed a part of being human, but it seems that most people don’t want to accept the responsibili ty for the problem. Perhaps it is the natural thing to do .The original quote about human nature went like this:” To err is human, to forgive, divine(神圣的).”This saying mirrors an i deal people should be forgiving of others’ mistakes. Instead, we tend to do the opposite –find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a mark of great maturity.Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Commonsense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine.Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company,” the right hand does not know what the left hand is doing.”And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people. Get the idea that it’s okay not to be totally honest all the time. There is a corollary(直接推论)to that: if good excuse is “good” even if it isn’t honest, then where is the place of the truth?1. According to the passage, which of following seems the most human?A. To search for truth.B. To achieve one’s idealC. To make fun of others’ mistakes.D. To criticize others for one’s own error. 2.According to the author, what is a sign of a man’s mat urity?A. Doing things his own way.B. Bearing responsibility for his mistakes.C. Making as few mistakes as possible.D. Thinking seriously about his wrongdoing.3.Which of the following is NOT based on common sense?A. A man tries to take charge of everything in a large company.B. A student goes out with an umbrella in stormy weather.C. A company’s next move follows a good plan.D. A lawyer acts on fine judgments.4. What is the author’s opinion about a good excuse?A. Making a good excuse is sometimes a better policy.B. Inventing a good excuse needs creative ideas.C. A good excuse is as rewarding as honesty.D. Bitter truth is better than a good excuse.5. What would be the best title for his passage?A. A Mirror of Human NatureB. To Blame or to ForgiveC. A Mark of MaturityD. Truth or ExcuseD(重庆)Sitting on the peaceful coast of the Galapagos Islands. Ecuador , watching the sun move quietly into the sea, you shouldn’t forget the Charles Darwin (1809 – 1882) arrived here in 1835. He stayed on the islands for five weeks, observing various animals. This finally inspired(启发) his famous work, On the Origin of Species. You can certainly follow Darwin’s footsteps and enjoy a trip from four to seven days to theislands.The islands are certainly a paradise (天堂) for wildlife, as there are no natural killers on the islands and the number of boats and visitors is under government control. Though you cannot walk freely as Darwin die hour 200 years ago ,each day is as impressive as it could be.The most well crown animal of the Galapagos is the giant tortoise ( 巨型陆龟),which can be seen moving slowly around the highlands of Santa Cruz, the second largest island in the archipelago(群岛). Some of these creatures are so old that they might have been seen in their youth by Darwin himself.Despite strict control over activities and timing, you stay on the Galapagos will be remembered as a chain of incomparable pictures; diving with sea how that swim and play within inches of you; feeling small sharks touch you feet as you swim and ,most magically , seeing a with and her baby surface with great breath of air.Traveling between the islands and observing the wildlife that so inspired Darwin, you will fell as though you are getting a special view of an untouched world .At night you will sleep on board the ship , leaving the wildlife in complete occupation of the islands, which are as undisturbed now as they have been since the beginning of time.1. What do we know about Darwin’s visit to the islands?A. He studied different creatures on the islands.B. He completed his famous book on the islands.C. He was touched by the geography of the islands.D. He was attracted by well-known animals of the islands.2. Which of the following plays a role in making the islands “a paradise for wildlife”?A. Animals on the islands feed on grass.B. Local government forbids killing wildlife.C. People cannot visit the islands as they wish.D. Tourists are not allowed to torch the animals.3.Your stay on the islands will be most impressive mainly because of .A. the beautiful sea viewsB. Darwin’s inspiring tripC.a closer view of animals D. various daring activities4.Which of the following would be the best title for the passage?A. A Unique Attraction for Wildlife LoversB. Galapagos as a Paradise for AdventurersC. Charles Darwin as a Symbol of GalapagosD. A Successful Example of Wildlife ProtectionE(重庆)Humans are naturally drawn to other life forms and the worlds outside of our own. We take delight in the existence of creatures and even whole societies beyond our everyday lives.This sense of wonder is universal look at the efforts that scientists have made to find out whether life of some kind exists on Mars, and the popularity of fantasy(幻想) literature or movies like The lord of the Rings, This sense of wonder draws us to each other, to the world around us, and to the world of make-believe. But have we gone to far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us?Human beings, as biologists have suggested, possess an inborn desire to connect with and understand other life forms, however, people, especially in big cities, often lead rather isolated lives. In a study of British schoolchildren, it was found that children by age eight were much more familiar with characters for television shows and video games than with common wildlife. Without modern technology, a small pond could be an amazing world filled with strange and beautiful plants, insects, birds, and animals. When we lack meaningful interaction (交互) with the world around us, and sometimes even with our families and friends , we seek to understand and communicate with things that exist only in our imaginations or on a computer screen The world of make-believe is not necessarily bad, But when the world of fantasy becomes the only outlet (出路) our sense of wonder, then we are really missing something, We are missing a connection with the living world. Otherwonderful wonderful worlds exist all around us. But even more interesting is that if we look closely enough, we can see that these worlds, in a broad sense, are really part of our own.1. The popularity of The Lord of the Rings proves ___ .A. the close connection between man and the fantasy worldB. the wonderful achievements of fantasy literatureC. the fine taste of moviegoers around the worldD. the general existence of the sense of curiosity2. What can we infer from the underlined sentence in Paragraph 3?A. People are far less familiar with the world of fantasy.B. The world around us could serve as a sound of wonder.C. The world of fantasy can be mirrored by a small and lively pond.D. Modern technology prevents us from developing our sense of wonder.3. If our sense of wonder relies totally on the world of make-believe. We will______.A. fail to appreciate the joy in our livesB. be confused by the world of make-believeC. miss the chance to recognize the fantasy worldD. be trapped by other worlds existing all around us4. What is the main purpose of the passage?A. To show us the hidden beauty in our world.B. To warn us not to get lost in the fantasy wonderC. To argue against the misuse of the sense of wonderD. To discuss the influence of the world of make-believe。

【例4】As they migrate, butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate. Many migrating birds do the same thing.The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.1. What’s the main idea of the text?A. Insects migrate with the seasons.B. Wind helps insects greatly in migrating.C. Windsurfing insects have real direction.D. Scientists have trouble in observing insectsConclusion: __________________________________________________________【例5】I suddenly heard an elephant crying as though frightened. Looking down I immediately recognized that something was wrong and ran down to the edge of the near bank. There I saw Ma Shwe with her three-month-old calf struggling in the fast-rising water and it was a life-and-death struggle. Her calf was floating and screaming with fear. Ma Shwe was as near to the far bank as she could get, holding her whole body against the rushing water and keeping the calf pressed against her huge body. Every now and then the rushing water would sweep the calf away.There was a sudden rise in the water and the calf was washed clean over the mother’s body and was gone. Ma Shwe turned quickly to reach it and pressed the calf with her head and trunk(象鼻) against the rocky bank. Then with a huge effort she picked it up in her trunk and tried until she was able to place it on a narrow shelf of rockJust at this moment she fell back into the river. If she were carried down it would be certain death I knew as well as she did ,that there was one spot(地点) where she could get up the bank but it was on the other side from where she had put her calfWhile I was wondering what I could do next I heard the sound of a mother’s love. Ma Shwe had crossed the river and got up the bank and was making her way back as fast as she could roaring(吼叫) all the time, but to her calf it was music.2. What can be the best title for the text?A. A Mother’s LoveB. A Brave ActC. A Deadly RiverD. A Matter of Life and DeathConclusion: __________________________________________________________【例6】When students and parents are asked to rate subjects according to their importance ,the arts are unavoidably at the bottom of the list . Music is nice, people seem to say, but not important. Too often it is viewed as mere entertainment, but certainly not an education priority(优先). This view is shortsighted. In fact, music education is beneficial and important for all students.Music tells us who we are. Because music is an expression of the beings who create it, it reflects their thinking and values, as well as the social environment it came from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity as a society.Music provides a kind of perception(感知) that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts explore emotive(情感的) meaning of the same phenomenon. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language of civilization through which we express our fears, our curiosities, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children access to an important way of expressing themselves such as music, we take away from them the meanings that music expresses.Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebration, the meaning and value of peace and love.So music education is far more necessary than people to realize.3. What is the main idea of the passage?A. Music education deserves more attention.B. Music should be of top education priority.C. Music is an effective communication tool.D. Music education makes students more imaginative.Conclusion: __________________________________________________________【例7】The best thing you can say about the roofs of most city building is that you don’t have to look at them much. That’s very good, since an urban lan dscape viewed from above can be an unlovely thing—block after block of tarred(铺有沥青的) black rooftops, sticky in summer, windswept in winter, ugly year-round. Or at least that’s the way it used to be.But urban roofs are going green. Environmental designers have begun to realize that the tops of buildings don’t have to be wastelands. Indeed, they can be gardens, planted with grasses, flowers and bushes.A planted roof usually comes in one of the two varieties: extensive or intensive. The extensive type is wide and shallow, with a soil depth of less than 8 inches, able to support smaller plants. The intensive type may smaller, but it’s relatively deeper and home to larger plants.Whatever the design, green roofs are not so simple as ordinary gardens. They have multiple layers beneath the soil, including a drainage layer, waterproofing, structural support, and so on.But this system can do a great deal of good. A recent paper in the journal BioScience tells that green roofs can control temperature, contain water and clean the air, And most impressively, they can cut heat loss from a building by 50%, lower air-conditioning costs by 25%, and reducethe urban-heated-island effect by 2°C.Of course, apart from the square feet greened and heat reduced, green roofs are even more valued since people can gain some psychological comfort simply by having a quiet place to go. As so often happens, what’s good for the planet can also be good for the sp irit.4. What can be the best title for the passage?A. Urban roofs going green.B. The advantages of planted roofsC. Urban roofs and rural roofsD. Extensive and intensive planted roofsConclusion: __________________________________________________________【例8】William Butler Yeats, a most famous Irish writer, was born in Dublin on June 13,1865. His childhood lacked the harmony (和睦) that was typical of a happy family. Later, Yeats shocked his family by saying that he remembere d “little of childhood but its pain”. In fact, he inherited (继承) excellent taste in art from his family ——both his father and his brother were painters. But he finally settled on literature , particularly drama (戏剧) and poetry.Yeats had strong faith in coming of new artistic movements. He set himself the fresh task in founding an Irish national theatre in the late 1890s.His early theatrical experiments, however, were not received favorably at the beginning. He didn’t lose heart, and finally enjoyed success in his poetical drama.Compared with his dramatic works, Yeats’s poems attract much admiring notice. The subject matter includes love, nature, history, time and aging. Though Yeats generally relied on very traditional forms, he brought modern sensibility to them. As his literary life progressed, his poetry grew finer and richer, which led him to worldwide recognition.He had not enjoyed a major public life since winning the Nobel Prize in 1923. Yet, he continued writing almost to the end of his life. Had Yeats stopped writing at age 40, he would probably now be valued as a minor poet, for there is no other example in literary history of a poet who produces his greatest works between the ages of 50 and 75. After Yeats’s death in 1939, W.H. Auden wrote, among others, the following lines:Earth, receive an honored guest:William Yeats is laid to rest.Let the Irish vessel (船) lieEmptied of its poetry5.
