    The average person learns most of the 30 000～40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious(意识到的) effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently(永久的)by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it.
    Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious(认真的), write the word and its meaning in a personal vocabulary list — preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days.
    Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read.
    Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing them enables you to make intelligent guesses about the meaning of words.
    If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited(继承) or borrowed much of its vocabulary of 500 000～600 000 words from Latin, Greek, French, Spanish and German.
    小题1:When you meet a new word in reading, what should you do?
    A．Guess its meaning. B．Ask somebody.
    C．Look it up in a dictionary. D．All of the above.
    小题2:According to this passage, the best way to build a good vocabulary is _______.
    A．to remember a lotB．to read a great deal
    C．to take part in a lot of good talksD．both B and C
    小题3:The phrase “be alert to” in the third paragraph may best be replaced by “_______”.
    A．look atB．pay attention to
    C．write downD．learn by heart
    小题4:In the fourth paragraph, the word “them” refers to _______.
    A．the parts of wordsB．prefixes
    C．suffixesD．roots

    小题1:D
    小题2:D
    小题3:B
    小题4:A

    怎样扩大词汇？捷径是：多读、多说、多听、多写。
    小题1:细节题。从第 2 段第2、3句话可知答案为 D。
    小题2:细节题。只要看到第 1 段第 2 句话The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks 可知答案为 D。
    小题3:词义猜测题。此处讲的是在“听”英语时如何对待生词的问题，根据我们“听”的经验选项A、C、D 显然可排除。
    小题4:词义猜测题。B、C、D三项都是属于the parts of words。

    Early people had very little effect on the environment. They lived in caves in very small “clan” groups. They collected or killed only enough for the clan’s survival. Early clans were nomadic, which mean that they didn’t stay in one place. Instead, they moved around, following the animals that were their main food source and seeking areas where seasonal plants grew wild. Moving around seasonally helped to protect the environment. The land had time to recover and animals had time to breed (繁殖)before the clan returned for the next season..
    As time went by, these small family clans joined with others to form larger groups for protection. Joining with other clans gave them more hunters and more women to help cut up the meat and share it between families. Eventually, people tamed(驯养)wild animals such as dogs and horses. People settled around rivers and fertile plains to share responsibilities and duties. Then, people began to plant crops instead of moving to areas where the plants grew. This development changed the environment.
    Traditional forms of work also changed. Some people were better at performing a particular task than other clan members, so then began to specialize in things they were good at doing. This also meant that they began to exchange their goods for things that others produced.
    People began to communicate with distant tribes. Land was cleared for roads. Foreign plants and animals were transported to places where they had not existed before. Specialization also give people more free time. So art ,dance and music became important ways of expressing feelings and thoughts. This was how many great civilizations started.
    Compared to the past, modern civilization has experienced many changes to become the highly developed society that exists today. Populations have increased rapidly. Forests have been cleared for farms. Inventions and technology have made work easier.
    However, pollution and other serious problems have also resulted from human progress. As concerned citizens, it is up to us to learn from past mistakes and to help maintain and improve our environment.
    小题1:Early tribes didn’t have much effect on animal population because_____
    A .they kept animals for themselves         B they ate only vegetables
    C they loved animals                     D they killed only enough for food
    小题2:The main purpose for small clans to join together was_____
    A to hurt animals                         B to seek safety
    C to share caves                         D to protect environment
    小题3:According to the passage ,we can learn that_____
    A early people moved to new places looking for new sources of food
    B modern civilization began when people started to live together in big groups
    C modern advancements are always good for the environment
    D people began to exchange goods because they didn’t have enough money
    小题4:It can be concluded from the passage that_____
    A human progress has brought civilization to the society
    B civilization has improved traditional forms of work
    C early people understood environmental protection
    D our environment has been affected by human progress

    To master a language one must be able to speak and understand the spoken language as well as to readand write. Lenin and his wife Krupskaya translated a long English book into Russian. But when theywent to England in 1902, English people couldn't understand what was said to them. These days more and more foreigners are coming to China and more Chinese are going out to foreign countries to work or study. So the spoken language is becoming more and more important.
    Speaking, of course, can't go without listening. If you want to pronounce a word correctly, first you must hear it correctly. The sounds of the Chinese and English languages are not exactly the same. If you don't listen carefully, you'll find it difficult or even impossible to understand the native speakers.
    Well, what about writing? Like speaking, it's to exchange ideas. People generally use shorter words and shorter sentences in their writing. The important thing is to make your idea clear in your head and then to write it in clear lively language.
    Chinese students read far too slowly. If you read fast, you understand better. If you read too slowly, by the time you have reached the end of a page you have forgotten what the beginning is about. When you meet with new words, don't look them up in the dictionary. Guess the meaning from the context(上下文). You may not guess quite correctly the first time, but as new words come up again and again in different contexts, their meaning will become clearer and clearer. If you look up every word, you'll never finish a book.
    Students of a foreign language need a particular knowledge, the knowledge of the life, history and geography of the people whose language they are studying. They should study these subjects in the
    foreign language, not only in translation. In this way one can kill two birds with one stone: learn a foreign language and get some knowledge of the foreign country at the same time.
    小题1: In the first paragraph, the writer told us _________.
    A．how to speak English well
    B．how to read and write English
    C．why spoken English is very important
    D．why English people couldn't understand Lenin
    小题2:In order to study a foreign language, the writer thinks the best way is ______.
    A．to kill two birds with one stone
    B．to learn two languages at a time
    C．to study all the subjects in a foreign language
    D．to get some knowledge of the foreign country as well as learn the language
    小题3: In the fourth paragraph the writer gave some advice on ____.
    A．how to imporve reading faster
    B．how to guess the meaning from the context
    C．how to look up new words in the dictionary
    D．how to grasp the general meaning of a passage
    小题4:"To kill two birds with one stone" means ____.
    A．to get some particular knowledge
    B．to get more than what one pays
    C．the stone is too big
    D．the birds are blind enough

    If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault(过错). But if he tells us that he has a poor memory, many of us think that his parents are to blame(受责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
    1. The main reason for one is poor memory is that _______.
    A. his father or mother may have a poor memory
    B. He does not use his name or legs for some time
    C. his memory is not often used
    D. he can’t read or write
    2. If you do not use your arms or legs for some time _______.
    A. you can’t use them any more      
    B. they will become stronger
    C. they become weak and won’t become strong until you use them again.
    D. they will become neither stronger nor weaker
    3. Which of the following is NOT true?
    A. Your memory works in the same way as your arms or legs.
    B. Your memory, like your arms or legs, becomes weak if you don’t give it enough chance for practice.
    C. Don’t learn how to read and write if you want to have a better memory.
    D. A good memory comes from more practice.
    4. Some people can’t read or write, but they usually have better memories, because _______.
    A. they have save much trouble           B. they have saved much time to remember things
    C. they have to use their memories all the time  D. they can’t write everything in a little notebook
    5. Which is the best title for this passage?
    A. Don’t Stop Using Your Arms Or Legs      B. How To Have a Good Memory

    Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
    In some modem countries it has for some time been fashionable to think that by free education for all — one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degree; they refuse to do what they think “low” work; and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
    In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
    小题1:The writer of the passage thinks that _______.
    A．education can settle most of the world’s problems
    B．free education for all probably leads to a perfect world
    C．free education won’t help to solve problems
    D．all the social problems can’t be solved by education
    小题2:The writer wants to prove that _______.
    A．our society needs all kinds of jobs
    B．our society needs free education for all
    C．a farmer is more important than a professor
    D．work with hands is the most important
    小题3:The purpose of education is _______.
    A．to choose officials for the country
    B．to prepare children mainly for their future work
    C．to let everyone receive education fit for him
    D．to build a perfect world
    小题4:The passage tells us about _______ of the education.
    A．the meansB．the systemC．the valueD．the type

    So long as teachers fail to distinguish (differ) between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
    Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to plan cleverly the most efficient(有效的) system for teaching themselves to read. Teaching is also a public activity: It can be seen and observed.
    Learning to read involves all that each individual does to understand the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
    If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the long search for knowledge? Smith has one principle rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
    When the roles of teacher and learner are seen for what they are, and when both teacher and learner fulfill them properly, then much of the pressure and feeling of failure for both is got rid of. Learning to read is made easier when teachers create an environment where children are given the chance to solve the problem of learning to read by learning.
    小题1:The problem with the reading course as mentioned in the first paragraph is that_______. 
    A．too much time is spent in teaching about reading
    B．reading tasks are given with little guidance
    C．it is one of the most difficult school courses
    D．students spend limited hours in reading
    小题2: The teaching of reading will be successful if _______. 
    A．teachers can make their teaching activities observable
    B．teachers can teach their students how to read
    C．teachers can improve conditions at school for the students
    D．teachers can enable students to develop their own way of reading
    小题3:The word “scrutiny” (Paragraph 3) most probably means “_______”.
    A．unbelief B．control C．inquiry D．observation
    小题4:The main idea of the passage is that_______.
    A．reading is more complicated than believable
    B．reading ability is something gained rather than taught
    C．teachers should encourage students to read as widely as possible
    D．teachers should do as little as possible in helping students learn to read

    Technology is the application(应用) of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has extended our life span via(通过) medical technology.
    Will mankind continue to live longer and have a higher quality of life? In large measure the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends upon research and development, and the latest statistics(统计) show that the United States is continuing to pump billions of dollars annually(每年) into such efforts. So while we are running out of some scarce resources(少的资源) we may well find technological substitutes(代用品)for many of them through our research programs.
    Therefore, in the final analysis the three major factors of production(land, labor and capital) are all influenced by technology. When we need new skills, on techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.
    小题1:What is the best title for the passage?
    A．The definition of technologyB．Modern technology
    C．The application of technologyD．The development of technology
    小题2:Which is the main idea of the passage?
    A．Modern technology is the key to the improvement of standard of living.
    B．The three major factors of production (land, labor and capital) are all influenced by technology.
    C．Technology is the response to our needs.
    D．The United States is making great efforts to advance its technology.
    小题3:According to the passage, people can live a long life with the help of _______.
    A．higher quality of life B．medical technology
    C．modern farming machineryD．technological substitute

    This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry.” This class was part of a study to answer the questions: Why is science difficult for many nonscience students? What can teachers learn about teaching if they take a class that is not in their field?
    The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing – the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.
    The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers (层次)　of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate(本科)　science classes, but it is important later, in graduate school. And it is always important in humanities(人文科学).
    Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make to make it an enjoyable experience for students.”
    But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better.
    小题1:What do we know about this unusual class?
    A．The teachers did lots of writing on the board
    B．The teacher were invited to attend several lectures.
    C．The student were professors from a university
    D．The students were studying science and humanities.
    小题2:The experiment was designed to find out             
    A．how to teach the students in the science class
    B．whether poetry is difficult for science students
    C．what to be taught in the humanities class
    D．why many humanities students find science hard.
    小题3:Finding levels of meaning is            .
    A．important for graduate students in humanities
    B．difficult for graduate students in humanities
    C．common for undergraduate students in science
    D．easy for undergraduate students in science.
    小题4:What did the science professors learn after the experiment?
    A．They should change the way they teach
    B．A poem could be explained in clear definitions.
    C．A poetry class could be more informative.
    D．Their teaching was an enjoyable experience.

    British scientists are breeding a new generation of rice plants that will be able to grow. in soil con­taining salt water. Their work may enable abandoned farms to become productive farms once more.
    Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences,. have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pairs have recently begun a three-year programme, funded by the Biotechnology and Bio­logical Sciences Research Council, to establish which genes enable some plants to survive salty condi­tions. The aim is to breed this capability into crops, starting with rice.
    It is estimated that each year more than 10 million hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts(防碍生长) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in. In Latin America, irrigation often causes problems when water is evaporated by the heat, leaving, salt deposits behind.
    Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.
    To overcome these problems. Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resul­ting seeds are ready to be considered for commercial use.
    Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food for the poorer countries of the world.
    4. Which of the following statements about Flowers and Yeo is true?
    A. They are students at Sussex University.  B. They are rice breeders.
    5. Which of the following is NOT mentioned as a cause of the problem discussed in the passage?
    A. Natural barriers to sea water have been destroyed.
    B. The water table has gone down after droughts.
    C. Sea level has been continuously rising.
    D. Evaporation of water leaves salt behind.
    6. The word "affect" in Paragraph 5 could be best replaced by________.
    A. influence               B. effect               C. stop                    D. present
    7. The attitude of the author towards the research project is________.
    A. positive                B. negative            C. suspicious             D. indifferent
