大学英语自学教程（上）电子版大学英语自学教程(上)01-A. How to be a successful language learner?“Learning a language is easy, even a child can do it!”Most adults who are learning a second language would disagree with this statement. For them, learning a language is a very difficult task. They need hundreds of hours of study and practice, and even this will not guarantee success for every adult language learner.Language learning is different from other kinds of learning. Some people who are very intelligent and successful in their fields find it difficult to succeed in language learning. Conversely, some people who are successful language learners find it difficult to succeed in other fields.Language teachers often offer advice to language learners: “Read as much as you can in the new language.”“Practice speaking the language every day. ”“Live with people who speak the language.”“Don’t translate-try to think in the new language.”“Learn as a child would learn; play with the language.”But what does a successful language learner do? Language learning research shows that successful language learners are similar in many ways.First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusion s. When they guess wrong, they guess again. They try to learn from their mistakes.Successful language learning is active learning. Therefore, successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate. They are not afraid to repeat what they hear or to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn to think in the language than to know the meaning of every word.1大学英语自学教程（上）电子版Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language regularly because they want to learn with it.What kind of language learner are you? If you are a successful language learner, you have probably been learning independently, actively, and purposefully. On the other hand, if your language learning has been less than successful, you might do well to try some of the techniques outlined above.01-B. LanguageWhen we want to tell other people what we think, we can do it not only with the help of words, but also in many other ways. For instance, we sometimes move our heads up and down when we want to say "yes” and we move our head s from side to side when we want to say "no." People who can neither hear nor speak (that is, deaf and dumb people) talk to each other with the help of their fingers. People who do not understand each other's language have to do the same. The following story shows how they sometimes do it.An Englishman who could not speak Italian was once traveling in Italy. One day he entered a restaurant and sat down at a table. When the waiter came, the Englishman opened his mouth, put his fingers in it, took them out again and moved his lips. In this way he meant to say, "Bring me something to eat." The waiter soon brought him a cup of tea. The Englishman shook his head and the waiter understood that he didn't want tea, so he took it away and brought him some coffee. The Englishman, who was very hungry by this time and not at all thirsty, looked very sad. He shook his head each time the waiter brought him something to drink. The waiter brought him wine, then beer, then soda-water, but that wasn’t food, of course. He was just going to leave the restaurant when another traveler came in. When this man saw the waiter, he put his hands on his stomach. That was enough: in a few minutes there was a large plate of macaroni and meat on the table before him.As you see, the primitive language of signs is not always very clear. The language of words is much more exact.2大学英语自学教程（上）电子版Words consist of sounds, but there are many sounds which have a meaning and yet are not words. For example, we may say "Sh-sh-sh” when we mean "keep silent.” When babi es laugh, we know they are happy, and when they cry, we know they are ill or simply want something.It is the same with animals. When a dog says “G-r-r” or a cat says "F-f-f” we know they are angry.But these sounds are not language. Language consists of words which we put together into sentences. But animals can not do this: a dog can say “G-r-r” when he means "I am angry,” but he cannot say first "I” and then "am” and then "angry.” A parrot can talk like a man; it can repeat whole sentences and knows what they mean. We may say that a parrot talks, but cannot say that it really speaks, because it cannot form new sentences out of the words it knows. Only man has the power to do this.02-A. Taxes, Taxes, and More TaxesAmericans often say that there are only two things a person can be sure of in life: death and taxes, Americans do not have a corner on the "death" market, but many people feel that the United States leads the world with the worst taxes.Taxes consist of the money which people pay to support their government. There are generally three levels of government in the United States: federal, state, and city; therefore, there are three types of taxes.Salaried people who earn more than a few thousand dollars must pay a certain percentage of their salaries to the federal government. The percentage varies from person to person. It depends on their salaries. The federal government has a graduated income tax, that is, the percentage of the tax (14 to 70 percent) increases as a person's income increases. With the high cost of taxes, people are not very happy on April 15, when the federal taxes are due.The second tax is for the state government: New York, California, North Dakota, or any of the other forty-seven states. Some states have an income tax similar to that of the federal government. Of course, the percentage for the state tax is lower. Other states have a sales tax, which is a percentage charged to any item which you buy in that state. For example, a person3大学英语自学教程（上）电子版might want to buy a packet of cigarettes for twenty-five cents. If there is a sales tax of eight percent in that state, then the cost of the cigarettes is twenty-seven cents. This figure includes the sales tax. Some states use income tax in addition to sales tax to raise their revenues. The state tax laws are diverse and confusing.The third tax is for the city. This tax comes in two forms: property tax (people who own a home have to pay taxes on it) and excise tax, which is charged on cars in a city. The cities use these funds for education, police and fire departments, public works and municipal buildings.Since Americans pay such high taxes, they often feel that they are working one day each week just to pay their taxes. People always complain about taxes. They often protest that the government uses their tax dollars in the wrong way. They say that it spends too much on useless and impractical programs. Although Americans have different views on many issues, they tend to agree on one subject: taxes are too high.02-B. AdvertisingAdvertising is only part of the total sales effort, but it is the part that attracts the most attention. This is natural enough because advertising is designed for just that purpose. In newspapers, in magazines, in the mail, on radio and television, we constantly see and hear the messages for hundreds of different products and services. For the most part, they are the kinds of things that we can be persuaded to buy – food and drinks, cars and television sets, furniture and clothing, travel and leisure time activities.The simplest kind of advertising is the classified ad. Every day the newspapers carry a few pages of these ads; in the large Sunday editions there may be several sections of them. A classified ad is usually only a few lines long. It is really a notice or announcement that something is available.Newspapers also carry a large amount of display advertising. Most of it is for stores or for various forms of entertainment. Newspapers generally reach an audience only in a limited area. To bring their message to a larger audience, many who want to put out their ads use national magazines. Many of the techniques of modern advertising were developed in magazine ads. The use of bright colors, attractive pictures, and short messages is all characteristic of magazine ads. The most important purpose is to catch the eye. The message itself is usually short, often no4大学英语自学教程（上）电子版more than a slogan which the public identifies with the product.The same techniques have been carried over into television advertising. Voices and music have been added to color and pictures to catch the ear as well as the eye. Television ads are short –usually only 15,30, or 60 seconds, but they are repeated over and over again so that the audience sees and hears them many times. Commercial television has mixed entertainment and advertising. If you want the entertainment, you have to put up with the advertising-and millions of people want the entertainment.The men and women in the sales department are responsible for the company’s advertising, They must decide on the audience they want to reach. They must also decide on the best way to get their message to their particular audience. They also make an estimate of the costs before management approves the plan. In most large companies management is directly involved in planning the advertising.03-A. The Atlantic OceanThe Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americas from being discovered by the people of Europe.Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it reached out to "the edge of the world." Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus crossed it. Even at its narrowest it is about 2, 000 miles (3,200 km) wide. This narrowest place is between the bulge of south America and the bulge of Africa.Two things make the Atlantic Ocean rather unusual. For so large an ocean it has very few islands. Also, it is the world's saltiest ocean.There is so much water in the Atlantic that it is hard to imagine how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It would take the ocean about 4,000 years to dry up. On the average the water is a little more than two miles (3.2 km) deep, but in places it is much deeper. The deepest spot is near Puerto Rico. This "deep"5大学英语自学教程（上）电子版30, 246 feet - almost six miles (9.6 km).One of the longest mountain ranges of the world rises the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands. The Azores are the tops of peaks in the mid-Atlantic mountain range.Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.Ocean currents are sometime called "rivers in the sea." One of these "river" in the Atlantic is called the Gulf Stream. It is a current of warm water. Another is the Labrador Current - cold water coming down from the Arctic. Ocean currents affect the climates of the lands near which they flow.The Atlantic furnishes much food for the people on its shores. One of its most famous fishing regions, the Grand Banks, is near Newfoundland.Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.We now have such fast ways of traveling that this big ocean seems to have grown smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New York to London in only eight hours and from South America to Africa in four!03-B. The MoonWe find that the moon is about 239,000 miles (384,551km) away from the earth, and, to within a few thousand miles, its distance always remains the same. Yet a very little observation shows that the moon is not standing still. Its distance from the earth remains the same, but its direction continually changes. We find that it is traveling in a circle - or very nearly a circle - round the earth, going completely round once a month, or, more exactly, once every 27 1/3 days. It is our nearest neighbour in space, and like ourselves it is kept tied to the earth by the earth's6大学英语自学教程（上）电子版gravitational pull.Except for the sun, the moon looks the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter is only 2, 160 miles (3,389 km), or a little more than a quarter of the diameter of the earth.Once a month, or, more exactly, once every 29 1/2 days, at the time we call "full moon," its whole disc looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part facing away from the sun appears dark. Artists could make their pictures better if they kept in mind -- only those parts of the moon which are lighted up by the sun are bright. This shows that the moon gives no light of its own. It merely reflects the light of the sun, like a huge mirror hung in the sky.Yet the dark part of the moon’s surface is not absolutely black; generally it is just light enough for us to be able to see its outline, so that we speak of seeing "the old moon in the new moon's arms." The light by which we see the old moon does not come from the sun, but from the earth. we knows well how the surface of the sea or of snow, or even of a wet road, may reflect uncomfortably much of the sun's light on to our faces. In the same way the surface of the whole earth reflects enough of the sun's light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.If there were any inhabitants of the moon, they would see our earth reflecting the light of the sun, again like a huge mirror hung in the sky. They would speak of earthlight just as we speak of moonlight. "The old moon in the new moon's arms" is nothing but that part of the moon's surface on which it is night, lighted up by earth light. In the same way, the lunar inhabitants would occasionally see part of our earth in full sunlight, and the rest lighted only by moonl ight; they might call this "the old earth in the new earth's arms.”04-A. Improving Your MemoryPsychological research has focused on a number of basic principles that help memory: meaningfulness, organization, association, and visualization. It is useful to know how these principles work.Meaningfulness affects memory at all levels. Information that does not make any sense to7大学英语自学教程（上）电子版you is difficult to remember. There are several ways in which we can make material more meaningful. Many people, for instance, learn a rhyme to help them remember. Do you know the rhyme “Thirty days has September, April, June, and November…? ” It helps many people remember which months of the year have 30 days.Organization also makes a difference in our ability to remember. How useful would a library be if the books were kept in random order? Material that is organized is better remembered than jumbled information. One example of organization is chunking. Chunking consists of grouping separate bits of information. For example, the number 4671363 is more easily remembered if it is chunked as 467,13,63. Categorizing is another means of organization. Suppose you are asked to remember the following list of words: man, bench, dog, desk, woman, horse, child, cat, chair. Many people will group the words into similar categories and remember them as follows: man, woman, child; cat, dog, horse; bench, chair, desk. Needless to say, the second list can be remembered more easily than the first one.Association refers to taking the material we want to remember and relating it to something we remember accurately. In memorizing a number, you might try to associate it with familiar numbers or events. For example, the height of Mount Fuji in Japan - 12, 389 feet - might be remembered using the following associations: 12 is the number of months in the year, and 389 is the number of days in a year(365) added to the number of months twice (24).The last principle is visualization. Research has shown striking improvements in many types of memory tasks when people are asked to visualize the items to be remembered. In one study, subjects in one group were asked to learn some words using imagery, while the second group used repetition to learn the words. Those using imagery remembered 80 to 90 percent of the words, compared with 30 to 40 percent of the words for those who memorized by repetition. Thus forming an integrated image with all the information placed in a single mental picture can help us to preserve a memory.04-B. Short-term MemoryThere are two kinds of memory: shore-term and long-term. Information in long-term memory can be recalled at a later time when it is needed. The information may be kept for days8大学英语自学教程（上）电子版mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning’s results suggest that beginning students hold the sound of words in their short-term memory, while advanced students hold the meaning of words in their short-term memory.05-A. Fallacies about FoodMany primitive peoples believed that by eating an animal they could get some of the good qualities of that animal for themselves. They thought, for example, that eating deer would make them run as fast as the deer. Some savage tribes believed that eating enemies that had shown bravery in battle would make them brave. Man-eating may have started because people were eager to become as strong and brave as their enemies.Among civilized people it was once thought that ginger root by some magical power could improve the memory. Eggs were thought to make the voice pretty. Tomatoes also were believed to have magical powers. They were called love apples and were supposed to make people who ate them fall in love.Later another wrong idea about tomatoes grew up - the idea that they were poisonous. How surprised the people who thought tomatoes poisonous would be if they could know that millions of pounds of tomatoes were supplied to soldiers overseas during World War II.Even today there are a great many wrong ideas about food. Some of them are very widespread.One such idea is that fish is the best brain food. Fish is good brain food just as it is good muscle food and skin food and bone food. But no one has been able to prove that fish is any better for the brain than many other kinds of food.Another such idea is that you should not drink water with meals. Washing food down with water as a substitute for chewing is not a good idea, but some water with meals has been found to be helpful. It makes the digestive juices flow more freely and helps to digest the food.10大学英语自学教程（上）电子版Many of the ideas which scientists tell us have no foundation have to do with mixtures of foods. A few years ago the belief became general that orange juice and milk should never be drunk at the same meal. The reason given was that the acid in the orange juice would make the milk curdle and become indigestible. As a matter of fact, milk always meets in the stomach a digestive juice which curdles it; the curdling of the milk is the first step in its digestion. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.Still another wrong idea about mixing foods is that proteins and carbohydrates should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk, probably the best single food, contains both proteins and carbohydrates. It is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.05-B. Do Animals Think?The question has often been asked, Do animals think? I believe that some of them think a great deal. Many of them are like children in their sports. We notice this to be true very often with dogs and cats; but it is true with other animals as well.Some birds are very lively in their sports; and the same is true with some insects. The ants, hardworking as they are, have their times for play. They run races; they wrestle; and sometimes they have mock fights together. Very busy must be their thoughts while engaged in these sports.There are many animals, however, that never play; their thoughts seem to be of the more sober kind. We never see frogs engaged in sport. They all the time appear to be very grave. The same is true of the owl, who always looks as if he were considering some important question.Animals think much while building their houses. The bird searches for what it can use in building its nest, and in doing this it thinks. The beavers think as they build their dams and their houses. They think in getting their materials, and also in arranging them, and in plastering them together with mud. Some spiders build houses which could scarcely have been made except by11大学英语自学教程（上）电子版some thinking creature.As animals think, they learn. Some learn more than others. The parrot learns to talk, though in some other respects it is quite stupid. The mocking bird learns to imitate a great many different sounds. The horse is not long in learning many things connected with the work which he has to do. The shepherd dog does not know as much about most things as some other dogs , and yet he understands very well how to take care of sheep.Though animals think and learn, they do not make any real improvement in their ways of doing things, as men do. Each kind of bird has its own way of building a nest, and it is always the same way. And so of other animals. They have no new fashions, and learn none from each other. But men, as you know, are always finding new ways of building houses, and improved methods of doing almost all kinds of labor.Many of the things that animals know how to do they seem to know either without learning, or in some way which we cannot understand. They are said to do such things by instinct; but no one can tell what instinct is. It is by this instinct that birds build their nests and beavers their dam and huts. If these things were all planned and thought out just as men plan new houses. there would be some changes in the fashions of them, and some improvements.I have spoken of the building instinct of beavers. An English gentleman caught a young one and put him at first in a cage. After a while he let him out in a room where there was a great variety of things. As soon as he was let out he began to exercise his building instinct. He gathered together whatever he could find, brushes, baskets, boots, clothes, sticks, bits of coal, etc., and arranged them as if to build a dam. Now, if he had had his wits about him, he would have known that there was no use in building a dam where there was no water.It is plain that, while animals learn about things by their senses as we do, they do not think nearly as much about what they learn, and this is the reason why they do not improve more rapidly. Even the wisest of them, as the elephant and the dog, do not think very much about what they see and hear. Nor is this all. There are some thing that we understand, but about which animals know nothing. They have no knowledge of anything that happens outside of their own observation. Their minds are so much unlike ours that they do not know the difference between right and wrong.12Comment [zzg6]: No matter how (what, who, when, where ,whether/if)大学英语自学教程（上）电子版young or old, large or small, traditional or modern, every family has a sense of what a family is. It is that feeling of belonging, of love and security that comes from living together, helping and sharing.There are basically two types of families: nuclear families and extended families. The nuclear family usually consists of two parents (mother and father) and their children. The mother and father form the nucleus, or center, of the nuclear family. The children stay in the nuclear family until they grow up and marry. Then form new nuclear families.The extended family is very large. There are often many nuclear families in one extended family. An extended family includes children parents, grandparents, uncles, aunts, and cousins. The members of an extended family are related by blood (grandparent, parents, children, brothers, sisters, etc.) or by marriage (husbands, wives, mothers-in-law, etc). They are all related, so the members of an extended family are called relatives.Traditionally, all the members of an extended family lived in the same area. However, with the change from an agricultural to an industrial society, many nuclear families moved away from the family home in order to find work. In industrial societies today, the members of most nuclear families live together, but most extended families do not live together. Therefore we can say that the nuclear family becomes more important than the extended family as the society industrializes.In post-industrial societies like the United States, even the nuclear family is changing. The nuclear family is becoming smaller as parents want fewer children, and the number of childless families is increasing. Traditionally, the father of a nuclear family earned money for the family while the mother cared for the house and the children. Today more than 50% of the nuclear families in the United States are two-earner families – both the father and the mother earn money for the family – and in a few families the mother earns the money while the father takes care of the house and the children. Many nuclear families are also “splitting up” –more and more parents are getting divorced.What will be the result of this “splitting” of the nuclear family? Social scientists now talk of two new family forms: the single parent family and the remarried family. Almost 20% of all American families are single parent families, and in 85% of these families the single parent is the mother. Most single parents find it very difficult to take care of a family alone, so they soon marry again and form remarried families. As social scientists study these two new family form, they will be able to tell us more about the future of the nuclear family in the post-industrial age.16。

大学英语自学教程(上册)课后答案及释义
大学英语自学教程（上册）课后答案及释义UNIT2Unit 2第一部分Text A【课文译文】税、税、还是税美国人常说，人的一生有两件事可以肯定会发生：死亡和税收。
美国人并不垄断死亡市场，但许多人却感到美国以最重的赋税领先于世界。
税指人们为支持政府而缴纳的资金。
在美国通常有三级政府：联邦政府，州政府及市政府，因此就存在三种税。
收入超过几千元的工薪人士必须向联邦政府缴纳一定比率的税金。
这一比率因人而异，取决于各人的工资数。
联邦政府实行累进收入所得税制，也就是说，税率(14%～70%)随个人收入的增加而增加，由于高额税收，人们在4月15日很不愉快，因为这一天是缴纳税款的日子。
第二种税是缴纳给州政府的，这些州包括纽约，加利福尼亚，北达科他以及其他47个州中的任何一个。
一些州的收入所得税的收取办法同联邦政府的相似，当然其税率要低一些。
一些州设有销售税，即对你在该州所购买的任何商品所收的一定比率的税金。
比如，某人想买一包25美分的烟。
如果该州收取8%的销售税，那么买这包烟要花27美分，这一钱数就包括销售税。
一些州利用收入所得税外加销售税的办法来提高税收，各州的税收法规五花八门，令人费解。
第三种税是向市政府缴纳的。
这种税有两种：一种是财产税(拥有房屋的人都必须交税)，另一种是本国消费税，即对城市汽车所征收的税金。
城市将这些资金用于教育、警察和消防部门、公共设施及市政建设。
由于美国人须付高额税金，所以他们经常感到每周有一天纯粹是在为缴税而工作。
人们总是在抱怨税收太高。
他们常常抗议政府滥用他们的税金。
