III.Reading Comprehension

Passage One

Computer people talk about the need for people to become computer-literate.But not all experts agree this is a good idea.One pioneer, in particular, who disagrees is David Tebbut, the founder of Computertown UK.Although many people see this as a successful attempt to bring people closer to the computer, David does not seethat way.He says that Computertwon UK was formed for just the opposite reason, to bring computers to people and make them people-literate.David Tebutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two.The clubs are for people who have some computer knowledge already.This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage

them and answer any questions they have.They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask.People don’t have to learn computer terms, but the experts have to explain in plain language.The computers are becoming people-literate.31.Which of the following is David Debutt’s idea on the relationship between people and

computers? A

A)Computer learning should be made easier.B)There should be more computer clubs for experts.C)People should work harder to master computer use.D)Computers should be made cheaper so that people can afford them.32.We can infer from the text that “computer-literate” means __D___.A)being able to afford a computer

B)being able to write computer programs

C)working with the computer and finding out its value

D)understanding the computer and knowing how to use it ]

33.The underlined word “it” in the second paragraph refers to the idea that Conputertowns _B_.A)help to set up more computer clubs

B)bring people to learn to use computers

C)bring more experts to work together

D)help to sell computers to the public

34.David Debutt started Computertwon UK with the purpose of __B___.A)making better use of computer experts

B)improving computer programs

C)increasing computer sales

D)popularizing computers

35.When computers are people-literate, ___B___.A)everybody can afford buy one

B)everybody, old and young, can use it easily

C)they will be too expensive for ordinary people to afford

D)only experts know how to operate a computer

Passage Two

A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands.While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.This attitude toward manual（體力的）labor is now still seen many aspects of American life.One is invited to dinner at a home that is not only comfortably but even luxuriously（豪華地）furnished and in which there is every evidence of the fact the family has been able to afford foreign travel, expensive hobbies, and college education for the children;yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery.On the contrary, the hostess usually takes

pride in careful preparation of special dishes.A professional may talk about washing the car, digging in his flowerbeds, painting the house.His wife may even help with these things, just as he often helps her with the dishwashing.The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.36.From paragraph 1, we know that in America ___D____.A.people tend to have a high opinion of the self-made man

B.people can always rise to the top through their own efforts

C.college professors win great respect from common workers

D.people feel painful to mention their fathers as labors

37.According to the passage, the hostess cooks dinner herself mainly because ___B____.A.servants in American are hard to getB.she takes pride in what she can do herself

C.she can hardly afford servantsD.It is easy to prepare a meal with canned food

38.The expression “wait on table” in the second paragraph means “____D___”.A.work in a furniture shopB.keep accounts for a bar

C.wait to lay the tableD.serve customers in a restaurant

39.The author’s attitude towards manual（體力的）labor is ___A____.A.positiveB.negativeC.humorous

40.Which of the following may serve as the best title of the passage?C

A.A Respectable Self-made Family.C.Characteristics of American Culture.D.critical B.American Attitude toward Manual Labor.D.The Development of Manual Labor.Passage Three

Australians and New Zealanders are famous for their love of the outdoors.They like to do as much as possible out in the sunshine, and this includes eating!

In the southern hemisphere, it's now early spring and many people are looking forward to warmer weather when they can enjoy barbeques(BBQs)with their friends and family.Almost every family has a unit to cook BBQ, whether it's a big modern one or a small well-used one.But whatever kind of BBQ unit you use, it means the same thing— delicious grilled food(燒烤食品)!

The most popular foods to barbeque are sausages, steaks, fish, and garlic bread.Kids love to toast marshmallows on sticks for dessert too.The outside of the marshmallow becomes crisp while the inside melts.It's yummy!Of course, you need to eat vegetables too and there are always different kinds of salads to eat with your grilled meat.The great thing about BBQs is you can take them anywhere.They are easy to carry so you can have a BBQ party at the beach, in a park, in your backyard or wherever you like.But remember to be careful using fire!Americans also like BBQs and in summer they often have outdoor BBQ parties in beautiful parks and backyard BBQs with their neighbors.41.This passage may be found in a ___D__.A.history bookB.science fiction

C.horror novelD.travel magazine

42.Australians and New Zealanders usually have outdoor BBQs __C___.A.during winter timeB.in restaurants

C.with friends and familyD.without vegetables

A.Meat.B.Vegetables.C.Fruits.D.Mashmallows.45.What is the last paragraph mainly about ?A

A.People can enjoy BBQs everywhere.B.We can frill all kinds of food.C.BBQs can be dangerous.Passage Four

The world itself is becoming much smaller by using modern traffic and modern communication means.Life today is much easier than it was hundreds of years ago, but it has brought new problems.One of the biggest is pollution.To pollute mean to make things dirty.Pollution comes in many ways.We see it, smell it, drink it and even hear it.Man has been polluting the earth.The more people, the more pollution.Many years ago, the problem was not so serious because there were not so many people.When the land was used up or the river was dirty in a place, men moved to another place.But this is no longer true.Man is now slowly polluting the whole world.Air pollution is still the most serious.It’s bad to all living things in the world, but it is not only one kind of pollution.Water pollution kills our fish and pollutes our drinking water.Noise pollution makes us become angry more easily.Many countries are making rules to fight pollution.They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.The pollution of SO2 is now the most dangerous problem of air pollution.It is caused by heavy traffic.It is sure that if there are fewer people driving, there will be less air pollution.The earth is our home.We must take care of it.That means keeping the land, water and air clean.And we must keep careful of the rise in pollution at the same time.46.Our world is becoming much smaller ______B_____.A.because the earth is being polluted day and night.B.thanks to scientific and technological development.C.because of the rise in pollution

Passage One Mr.and Mrs.White had two sons and three daughters．One Sunday，Mrs.White said to her husband，“The children don't have any lessons today，and you're free too．There's a new funfair（廟會）in the park．Let's all go there to play.”

Her husband said，“I want to finish some work today.”“oh, forget it．Go there and make our children happy．That's the most important work” Mrs.White said.So Mr.and Mrs.White took their children to the funfair．Mr.White was forty-five years old.But he enjoyed the funfair more than his children.He hurried from one thing to another，and ate lots of sweets.One of the children said to her mother，“Dad is just like a small child，isn't he, Mom?” Mrs.White didn't want to follow her husband around any more at that time and answered，“He is even worse than a small child，Mary，because he might spend more money than a small child.” 1.There were five children in the White family.A)T √

Passage Two People have been talking about health for a long time because people know the importance of it.People's understanding of health also becomes deeper with the progress in scientific research.Recently the term “health” has come to have a wider meaning than it used to.It no longer means just the absence of illness.Today, health means the well-being of your body, your mind and your relationship with other people.This new concept of health is closely related to another term－quality of life.Quality of life is the degree of overall satisfaction that a person gets from life.Why has the emphasis of health shifted from the absence of disease to a broader focus on the quality of a person's life? One reason for this has to do with the length and conditions of life that people can now expect.Medical advances have made it possible for people today to live longer, healthier lives.Imagine for a moment that you were born in the year 1900.You could have expected on average to live until about the age of 47.In contrast, if you were born in the year 1999, you could expect to live to the age of 75.6.Progress in scientific research leads to people's deeper understanding of health.A)T √

Passage Three We often use gestures to express our feelings, but the problem is that the gestures can be understood in different ways.It is true that a smile means the same thing in any language.So does laughter or crying.Fear is another emotion that is shown in much the same way all over the world.In Chinese and in English literature, a phrase like “he went pale and began to tremble” suggests that the man is either very afraid or he has just got a very big shock.However, “he opened his eyes wide” is used to suggest anger in Chinese, whereas in English it means surprise.In Chinese, surprise can be described in phrase like “they stretched out their tongues!” “Stretching out our tongue” in English is an insulting gesture or expresses strong dislike.Even in the same culture, people differ in their ability to understand and express feelings.Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people’s faces.Other studies show that older people usually find it easier to recognize or understand body language than younger people do.11.Which of the following is true according to the passage? D

A)We can easily understand what people’s gestures mean.B)Words can be better understood by older people.C)Gestures can be understood by most people but words are not.D)It is difficult to tell what people’s gestures really mean sometimes.12.People’s facial expressions may be misunderstood in different cultures because ____D__.A)people of different sexes may understand a gesture differently

B)people speaking different languages have different facial expressions

C)people of different ages may have different interpretations

D)people from different cultures have different meanings about some facial expressions.13.From the passage, we can conclude that __A___.A)gestures can be used to express feelings

B)gestures can be more effectively used than words to express feelings

C)words are often more difficult to understand than gestures

D)gestures are used as frequently as words to express feelings 14.In the same culture, people ___D___.A)hardly ever fail to understand each other’s ideas and feelings

B)are equally intelligent even if they have different backgrounds

C)almost all have the same understanding of the same thing

D)may have different abilities to understand and express feelings 15.The best title for this passage can be __C____.A)Gestures

B)Feelings

C)Gestures and Feeling D)Culture and Understanding

Passage Four There are three kinds of goals: short-term, medium-range and long-term goals.Short-term goals are those that usually deal with current activities, which we can apply on a daily basis.Such goals can be achieved in a week or less, or two weeks, or possibly, months.It should be remembered that just as a building is no stronger than its foundation, long-term goals cannot amount to very munch without the achievement of solid short-term goals.Upon completing our short-term goals, we should date the occasion and then add new short-term goals that will build on those that have been completed.The intermediate goals build on the foundation of the short-term goals.They might deal with just one term of school or the entire school year, or they could even extend for several years.Any time you move a step at a time, you should never allow yourself to become discouraged or overwhelmed.As you complete each step, you will enforce the belief in your ability to grow and succeed.And as your list of completion dates grow, your motivation and desire will increase.Long-term goals may be related to our dreams of the future.They might cover five years or more.Life is not a static thing.We should never allow a long-term goal to limit us or our course of action.16.Our long-term goals mean a lot ___B____.A)if we cannot reach solid short-term goals B)if we complete the short-term goals C)if we have dreams of the future D)if we put forward some plans 17.New short-term goals are built upon__D___.A)a daily basis B)your achievement in a week C)current activities D)the goals that have been completed 18.When we complete each step of our goals, _C___.A)we will win final success B)we are overwhelmed C)we will build up our confidence to achieve success D)we should have strong desire for setting new goals 19.What is the main idea of this passage? __C___ A)Life is a dynamic thing.B)We should set up long-term goals.C)Different kinds of goals in life.D)The limitation of long-term goals.20.Which of the following statements is wrong according to the passage? __C___ A)The long-term goals cannot amount to very munch without achieving short-term goals.B)The intermediate goals build on the foundation of the short-term goals.C)Life is a static thing, thus never allowing a long-term goal to limit us.D)We should often add new short-term goals to what have been completed.Part IV Cloze The world is not only hungry;it is also thirsty for water.This may seem strange to you, since nearly 75% of the earth's surface is covered with water.But about 97% of this huge amount is seawater, __B__ salt water.Man can only drink and use the other 3% of the fresh water that comes from rivers, lakes, underground, and other __C__.And we can't even use all of that, because some of it is in the form of icebergs and glaciers.Even worse, some of it has been polluted.However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us.But our need __D__ water is increasing rapidly-almost day by day.We all have to learn how to stop wasting our previous water.One of the first steps we should __A__ is to develop ways of reusing it.Experiments have already been done in this __E_, but only on a small scale.The systems that have been worked out resemble those used in spacecraft.1.A)take B)or C)sources D)for E)case 2.A)take B)or C)sources D)for E)case 3.A)take B)or C)sources D)for E)case 4.A)take B)or C)sources D)for E)case 5.A)take B)or C)sources D)for E)case

Part VI Sample Writing East or West, Home is Best 金窩，銀窩，不如自己的狗窩 What’s the best place in your heart? If I ask you where the best place is in your heart, perhaps you may say it’s Zhongnanhai, the White House or the Kremlin Palace.But I’ll tell you that it’s home rather than any one of them.Because a proverb says well that “East or west, home is best.”

That’s why? Because home is the port of our soul and the only one place that we are looking forward to going for the whole life.Because I think home means all to me and anybody else.It’s home where we can go whenever we are hurt or tired.It is also home where we can enjoy the feelings of parents, brothers and sisters.It’s home that that fights against wind or rain whether in the day time or at night.In a word, whatever we do and wherever we go, home is the best place that we can go forever.How to Overcome Difficulties in My English Studies 如何克服英語學習的困難

My View on Fate 1.有人認為我們可以掌握自己的命運，有人則認為不能；

2.你的看法如何？說明你的理由并且適當舉例。

3.結論。

MY VIEW ON FATE Do you believe fate? There are a amount of different views.To different people, the definition to fate is almost not the same.Some people consider that one’s fate is destined while he comes into the world and nothing can change it.Besides some people hold their views that one’s fate are controlled by themselves.From my own perspective, I am the latter one.No matter who we are and no matter where we from, we have the chance to hold our own fate.For instance, Helen Keller.As we all known, she is blind and deaf when she was only 19 months old.However, she never believes her fate.She showed great courage and confidence to fight her life.At last, she gained what we able-bodies person couldn’t have.She told us that if we don’t bow to the fate, everybody can change it.There is a saying goes, “Everyone is the architect of his own future.” We should believe ourselves but the fate.Love and Care for the Handicapped 關愛殘疾人

1． 殘疾人作為社會的一個特殊群體需要更多的關愛和幫助。2． 關愛殘疾人重在轉變觀念，即把他們視為獨立、平等的個體，同時我們還應該致力于為殘疾人創造一個更便利的生活環境。3． 殘疾人也有自己的優勢，所以在關愛殘疾人的同時我們自己也將受益匪淺。

China has an estimated 83 million disabled people, accounting for about 6.3 percent of the country’s population.To ensure a better life for this special group of people, it calls for more love and care from the rest of the society.However, nowadays some people still harbored some kind of prejudice against the handicapped.Therefore, a change in their attitudes is of top priority.Just as the sign language hostess from the China Disabled Art Performing Troupe, Jiang xintian, often “said” with her hands that “Life is full of ups and downs, and our life is not unlucky but just inconvenient.”, so the best way to show our love and care is to offer them the respect and dignity bestowed with every individual.Only when we treat them as equals would they enjoy the opportunity to become more independent members of this society and fulfill their dreams confidently.In addition, joined efforts should be devoted to creating a more convenient living environment for the handicapped.Among the many other things we can do for them is the construction and installation of barrier-free facilities, such as special lanes for the blind, low chassis(底架，底盤)barrier-free buses, or wheelchair ramps(坡道)in public places, which will not only greatly ease the lives of the handicapped but also benefit any ordinary individual such as a mother with a baby stroller.As the saying goes “When God closes a door, He opens a window.” most physically-challenged people have their own strengths.Either the acute sense of hearing of a blind, or the expressive body language of a deaf and dumb may serve as a perfect example.What impressed us most deeply would be the optimism, courage and perseverance showed by those disabled athletes, and it is they who help us to gain new insights into the true meaning of life.Thus, while we are extending a helping hand to the physically-challenged, we are virtually learning even more from them, learning a more positive attitude towards life and learning to be a more complete human being.What Does Fame Bring? 1.人不擇手段追求成名的原因是……； 2.有人認為名聲給人帶來更多麻煩； 3.我的看法。學生回答: Nowadays, there're a large amount of people.seeking for fame.To them, “fame” is an attractive thing.Most of people who go after fame and money consider that fame will bring them a lot.In their views, fame can not only bring money to make themselves rich, but also they do things will be more convenient.For example, you go to a restaurant and it is very busy, if you were a famous people, you need not to wait.However there are also other people who hold a negative view toward fame.In their views, fame may produce so many troubles.From my own perspective, I am one of the latter.Once one gain the fame and he gets some it, he wants to continue chasing it.In order to keep himself famous, he has to performing in the same way.Maybe this way is not the way he likes to.From day to day, he forgets what is he really like to do and to be.At last, he lost the most precious thing freedom.In one word, we could not let ourselves to be a publicity-seeking clown.答案: What Does Fame Bring? Generally speaking, “Fame” is an attractive thing people chase after, because it always brings wealth, admiration from others and high social status.However, there are also other people who hold a negative view toward fame and I am one of the latter.In my opinion, fame is not only a burden, but also a trap.Usually people gain fame because they possess a single talent or skill: singing, painting, or writing, etc.These people develop a style that make them distinctive and gain popularity.In order to keep this popularity, they have to continue performing in the same way, since this is what the public want.However, as time goes on, the singer may become bored singing the same songs in the same way, or the painter becomes bored painting similar scenes or portraits, but the demand of the public doesn’t allow them to make changes;if the artist attempts to change his or her style of writing or dancing or singing, the public may abandon him or her.As a result, the artist can’t make his or her decision but has to live a life they don’t want.Thus chasing fame is just like an animal chasing its own tail and when he captures it, he does not know what else to do but to continue chasing it.In one word, fame is more like a trap than a blessing and I don’t want it myself.

第五篇：大學英語四級作文練習

大學英語四級作文練習-記敘文

距離2012年6月份的英語四級考試越來越近，考生應在有限的時間內做好大學英語四級作文練習，在此為大家整理記敘文的思路及大學英語四級作文范文。

大學英語四級作文練習之記敘文的思路與練習

記敘文是以敘述人物的經歷和事物的發展變化過程為主要表現形式的一種文體。記敘文既可以以寫人為主，又可以以寫事為主。寫記敘文要注意記敘文的“六大要素”即：

時間(When)—— 何時發生，有沒有具體時間?

地點(Where)—— 何地發生，有沒有地點變化?

人物(Who)—— 何人參與，誰是主角?

事件(What)—— 發生了什么，有何特點?

原因(Why)—— 事件的起因?

結果(How)—— 事件的經過及結局?

一般說來，在一篇記敘文中這六大要素是缺一不可的。記敘文的思路就圍繞這六大要素充分展開。

【例】四級考試中，只出現過一次專門的記敘文體裁的寫作，即“An Early Morning Walk”(1988.6.)，2003年6月出現過包含記敘文的作文，即“An Eye-Witness Account of a Traffic Accident”。

對于“An Early Morning Walk”，知道命題要求后，我們就要開始構思了。

When：題目已規定了是“清晨”，在這個時候，“我”去散步。Where：到哪兒散步?去公園?在校園里?在街上(街上空氣不好，還是不去!)。

Who：在公園里看到晨練的人：中老年人、年輕人、小孩子;在校園里看到讀書背單詞的學生。

What：人們熱火朝天地做操，隨音樂跳舞，打球，等等。

Why：清晨空氣清新，適合鍛煉;一日之際在于晨，背背書，讀讀單詞。

當然，由這個題目可以令人想到很多東西，因篇幅所限，我們做了刪減。

大學英語四級作文范文

An Early Morning Walk

One morning I got up very early，and everything around was very quiet.The sun had just risen，shining brilliantly and everything seemed to be covered with a layer of golden silk.There were only some birds singing occasionally in the tall trees.I strolled along the street toward the park，breathing the fresh air and feeling extremely happy.When I arrived at the park，I found，to my surprise，that there were so many people there.Men and women，boys and girls，all were enjoying themselves in their various activities.Some were doing morning exercises，some were playing badminton and some old people were having their tea while talking to each other cheerfully.I wandered around the park.To my delight，I found a few

middle-school students talking to each other in English in one corner of the park.I went up and spoke to them in English.We soon became friends.I was very glad to find another opportunity to practice my spoken English.On the way home，I realized that an early morning walk really was good and healthful.Taking early morning walks makes one healthy and wise.
