“Welcome to the U.S.A.! Major credit cards are accepted!”By the millions they are coming no longer the tired, the poor, the wretched masses longing for a better living. These are the wealthy. “We don’t have a budget,” says a biologist from Brazil, as she walks with two companions through New York City’s South Street. “We just use our credit cards.”The U.S. has long been one of the world’s most popular tourist destinations, but this year has been exceptional. First, there was the World Cup, which drew thousands from every corner of the globe; then came the weakening of the U.S. dollar against major currencies. Now the U.S., still the world’s superpower, can also claim to be the world’s bargain basement (廉价商品部). Nobody undersells America these days on just about everything, from consumer electronics to fashion clothes to tennis rackets. Bottom retail prices anywhere from 30% to 70% lower than those in Europe and Asia have attracted some 47 million visitors, who are expected to leave behind $79 billion in 1994. That’s up from $74 billion the year before.True, not everyone comes just for bargains. There remains an undeniable fascination in the rest of the world with all things American, nourished by Hollywood films and U.S. television series. But shopping the U.S.A is proving irresistible. Every week thousands arrive with empty suitcases ready to be filled; some even rent an additional hotel room to hold their purchases. The buying binge (无节制) has become as important as watching Old Faithful Fountains erupt in Yellowstone Park or sunbathing on a beach in Florida.The U.S. has come at last to appreciate what other countries learned long ago: the pouring in of foreign tourists may not always be convenient, but it does put money in the bank. And with a trade deficit at about $130 billion and growing for the past 12 months, the U.S. needs all the deposits it can get. Compared with American tourists abroad, visitors to the U.S. stay longer and spend more money at each stop; an average of 12.2 night and $1624 a traveler versus the Americans’ four nights and $298.1. From what the Brazilian biologist says, we know that tourists like her ______.2. The reason why 1994 was exceptional is that ______.3. By saying “Nobody undersells America” (Underlined), the author means that ______.4. Why does the author assert that all things American are fascinating to foreigners?5. From the passage we can conclude that the U.S. has come to realize ______.

I made a pledge to myself on the way down to the vacation beach cottage. For two weeks I would try to be a loving husband and father. Totally loving. No ifs, ands or buts.The idea had come to me as I listened to a talk on my car radio. The speaker was quoting a Biblical (圣经的) passage about husbands being thoughtful of their wives. Then he went on to say, “Love is an act of will. A person can choose to love.” To myself, I had to admit that I had been a selfish husband. Well, for two weeks that would change.And it did. Right from the moment I kissed Evelyn at the door and said, “That new yellow sweater looks great on you.”“Oh, Tom, you noticed,” she said, surprised and pleased. Maybe a little puzzled.After the long drive, I wanted to sit and read. Evelyn suggested a walk on the beach. I started to refuse, but then I thought, “Evelyn’s been alone here with the kids all week and now she wants to be alone with me.” We walked on the beach while the children flew their kites.So it went. Two weeks of not calling the Wall Street firm where I am a director; a visit to the shell museum though I usually hate museums. Relaxed and happy, that’s how the whole vacation passed. I made a new pledge to keep on remembering to choose love.There was one thing that went wrong with my experiment, however. Evelyn and I still laugh about it today. On the last night at our cottage, preparing for bed, Evelyn stared at me with the saddest expression.“What’s the matter?” I asked her.“Tom,” she said in a voice filled with distress, “do you know something I don’t?”“What do you mean?”“Well… that checkup (体检) I had several weeks ago… our doctor… did he tell you something about me? Tom, you’ve been so good to me… am I dying?”It took a moment for it all to sink in. then I burst out laughing.“No, honey,” I said, wrapping her in my arms. “You’re not dying; I’m just starting to live.”1. In the first paragraph, “No ifs, ands or buts” probably means “______”.2. From the story we may infer that Tom drove to the beach cottage ______.3. During the two weeks on the beach, Tom showed more love to his wife because ______.4. The author says, “There was one thing that went wrong with my experiment.” What was the one thing that went wrong?5. By saying “I’m just starting to live,” Tom means that ______.

Much of Canada’s forestry production goes towards making pulp and paper. According to Canadian Pulp and Paper Association, Canada supplies 34% of the world’s wood pulp and 49% of its newsprint paper. If these paper products could be produced in some other way, Canadian forests could be preserved. Recently, a possible alternative way of producing paper has been suggested by agriculturalists and environmentalists: a plant called hemp.Hemp has been cultivated by many cultures for thousands of years. It produces fiber which can be made into paper, fuel, oils, textiles, food, and rope. For centuries, it was essential to the economies of many countries because it was used to make the ropes and cables used on sailing ships; colonial expansion and the establishment of a world-wide trading network would not have been feasible without hemp. Nowadays, ships’ cables are usually made from wire or synthetic fibers, but scientists are now suggesting that the cultivation of hemp hold be revived for the production of paper and pulp. According to its proponents, four times as much paper can be produced from land using hemp rather than trees, and many environmentalists believe that the large-scale cultivation of hemp could reduce the pressure on Canada’s forests.However, there is a problem: hemp is illegal in many countries of the world. This plant, so useful for fiber, rope, oil, fuel and textiles, is a species of cannabis, related to the plant from which marijuana is produced. In the late 1930s, a movement to ban the drug marijuana began to gather force, resulting in the eventual banning of the cultivation not only of the plant used to produce the drug, but also of the commercial fiber-producing hemp plant. In fact, marijuana cannot be produced from the hemp plant, since it contains almost no THC (the active ingredient in the drug).In recent years, a movement for legalization have been gathering strength. It is concerned only with the hemp plant used to produce fiber; this group wants to make it legal to cultivate the plant and sell the fiber foe paper and pulp production.1. Why is pulp and paper production important to Canada?2. Why was the plant hemp essential to world-wide trade in the past?3. Why do agriculturalists think that hemp would be better for paper production than trees?4. Why was hemp banned?5. “According to its proponents, four times as much paper can be produced from land using hemp rather than trees.” What does “proponents” mean?

Therefore there are critical (10) times for language development. Current (11) of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable.

(20), children learn language from their parents by imitating them. Parents gradually shape their child’s language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

The two most obvious changes in American economy are the emergence of a highly sophisticated technology and the rise of giant corporations. In addition, market forces have lost some of their significance as planning has become more important. The government has assumed a greatly changed role in the economy. Property relationships and decision-making power have shifted. The demand for highly educated specialists has increased enormously.We may think of the American economy, as consisting of two completely different sectors. The world of the giant corporations, which can be called the “industrial system”, consists of 500 or 600 firms that provide “nearly all communications, nearly all production and distribution of electric power, much transportation, most manufacturing and mining, a substantial share of retail trade, and a considerable amount of entertainment”. Outside of this industrial system fall most agricultural enterprises, some mining and trucking, professional and artistic pursuits, some retail trade, and most personal and domestic services.The classical economic laws of supply and demand still apply to some degree. But today the industrial sector is characterized far more by planning and certainty than by the free play of market forces. It appears that it could scarcely be otherwise. In large corporations with advanced technological systems and complex organizations of highly trained specialists, plans for producing any one item are made well in advance. Such plans, once made, are hard to change. Because long-term planning demands certainty, market forces are avoided by various means. For example, the corporation may achieve “vertical integration” by buying companies that supply raw materials at one end of the process and distribution outlets at the other. Corporations may agree on “just prices” for things they buy and sell. They may enter mutually advantageous long-term contracts with suppliers and customers. Moreover, in their quest for certainty they generally have the support of the state.1. The American giant corporations possess so many new characteristics that ______.2. By the second paragraph, we know that ______.3. From the whole passage, we can infer that American economy ______.4. In the third sentence of last paragraph, the second “it” may refer to ______.5. Which of the following is not mentioned in the passage?

Laziness is a sin, everyone knows that. We have probably all had lectures pointing out that laziness is immoral, that it is wasteful, and that lazy people will never amount to anything in life. But laziness can be more harmful than that, and it is often caused by more complex reasons than simple wish to avoid work. Some people who appear to be lazy are suffering from much more serious problems. They may be so distrustful of their fellow workers that they are unable to join in any group task for fear of ridicule or fear of having their ideas stolen. These people who seem lazy may be paralyzed by a fear of failure that prevents fruitful work. Or other sorts of fantasies may prevent work; some people are so busy planning, sometimes planning great deals or fantastic achievements, that they are unable to deal with whatever “lesser” work is on hand. Still other people are not avoiding work; strictly speaking, they are merely procrastinating—rescheduling their day.Laziness can actually be helpful. Like procrastinators (拖延者), some people may look lazy when they are really thinking, planning, contemplating, researching. We should all remember that some great scientific discoveries occurred by chance or while someone was “goofing off (游手好闲)”, Newton wasn’t working in the orchard when the apple hit him and he devised the theory of gravity. All of us would like to have someone “lazy” build the car or stove we buy, particularly if that “laziness” were caused by the worker’s taking time to check each step of his work and to do his job right. And sometimes, being “lady”—that is, taking time off for a rest-is good for an overworked student or, executive. Taking a rest can be particularly helpful to the athlete who is trying too hard or the doctor who’s simply working himself overtime too many evenings, at the clinic. So be careful when you’re tempted to call someone lazy. That person may be thinking, resting, or planning his or her next book.1. The main idea of this passage is that ______.2. The passage states that ______.3. Which of the following conclusion does the passage support?4. The final paragraph is ______.5. The word “devised” in Para. 2 means ______.

Bringing up children is a hard work, and you are often to blame for any bad behavior of your children. If so, Judith Rich Harris has good news for you. Parents, she argues, have no important long-term effects on the development of the personality of their children. Far more important are their playground friends and neighborhood. Ms. Harris takes to hitting the assumption, which has dominated developmental psychology for almost half a century.Ms. Harris’s attack on the developmentalists’ “nature” argument looks likely to reinforce doubts that the profession was already having. If parents matter, why is it that two adopted children, reared in the same home, are no more similar in personality than two adopted children reared in separate homes? Or that a pair of identical twins, reared in the same home, are no more alike than a pair of identical twins reared in different homes?Difficult as it is to track the precise effects of parental upbringing, it may be harder to measure the exact influence of the peer (同龄人) group in childhood and adolescence. Ms. Harris points to how children from immigrant homes soon learn not to speak at school in the way their parents speak. But acquiring a language is surely a skill, rather than a characteristic of the sort developmental psychologists hunt for. Certainly it is different from growing up tensely or relaxed, or from learning to be honest or hard-working or generous. Easy though it may be to prove that parents have little impact on those qualities, it will be hard to prove that peers have vastly more.Moreover, mum and dad surely cannot be ditched completely. Young adults may, as Ms. Harris argues, be keen to appear like their peers. But even in those early years, parents have the power to open doors: they may initially choose the peers with whom their young associate, and pick that influential neighborhood. Moreover, most people suspect that they come to resemble their parents more in middle age, and that people’s child bearing habits may be formed partly by what their parents did. So the balance of influences is probably complicated, as most parents already suspected without being able to demonstrate it scientifically. Even if it turns out that the genes they pass on and the friends their children play with matter as much as affection, discipline and good example, parents are not completely off the hook.1. According to Ms. Harris, ______.2. Which of the following views is consistent with what the developmentalists hold?3. According to Para. 3, which of the following statements is TRUE?4. The word “ditched” could be best replaced by ______.5. What is the author’s main purpose?

Many of the most damaging and life threatening types of weather torrential rains, severe thunderstorms, and tornadoes begin quickly, strike suddenly, and disappear rapidly, destroying small regions while leaving neighboring areas untouched. Such event as a tornado struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $250 million, the highest ever for any Canadian storm.Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.Until recently, the observation intensive approach needed for accurate, very short-range forecasts, or “Nowcasts”, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome. Fortunately, scientific and technological advances have overcome most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information. Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.1. The word “exceeded” in paragraph 1 most probably means ______.2. Conventional computer models of the atmosphere fail to predict such a short-lived tornado because ______.3. According to the passage, the word “Nowcast” (paragraph 3) means ______.4. According to the passage, ______ is the key factor to making “Nowcasts” a reality.5. According to the author, the passage mainly deals with ______.

A wise man once said that the only thing necessary for the triumph of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people.Days after days my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability.Accountability isn’t hard to define. It means that every person is responsible for his or her actions and liable for their consequences.Of the many values that hold civilization together—honesty, kindness, and so on—accountability may be the most important of all. Without it, there can be no respect, no trust, no law—and, ultimately, no society.My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people’s behavior are far less effective than internal restraints such as guilt, shame and embarrassment.Fortunately there are still communities—smaller towns, usually—where schools maintain discipline and where parents hold up standards that proclaim: “In this family certain thing are not tolerated—they simply are not done!”Yet more and more, especially in our larger cities and suburbs, these inner restraints are loosening. Your typical robber has gone. He considers your property his property; he takes what he wants, including your life if you enrage him.The main cause of this break-down is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it’s the criminal who is considered victimized: by his underprivileged upbringing, by the school that didn’t teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn’t provide a stable home.I don’t believe it. Many others in equally disadvantaged circumstances choose not to engage in criminal activities. If we free the criminal, even partly, from accountability, we become a society of endless excuses where no one accepts responsibility for anything.We in America desperately need more people who believe that the person who commits a crime is the one responsible for it.1. What the wise man said suggests that ______.2. According to the author, if a person is found guilty of a crime, ______.3. Compared with those in small towns, people in large cities have ______.4. The writer is sorry to have noticed that ______.5. The key point of the passage is that ______.

As the English language has changed at a fast speed in this century, so has the use of the English language.After the British Broadcasting Corporation (BBC) was founded in 1927, the particular style of speech of the BBC announcers was recognized as Standard English or Received Pronunciation (RP) English. Now, most people still consider that the pronunciation and delivery of BBC announcers is the clearest and most understandable spoken English.English has had a strong association with class and social status. However, since the Second World War there has been a considerable change of attitude towards speech snobbery, and hallmarks of class distinction such as styles of speech have been gradually discarded, especially by the younger generation.As the need has arisen, new words have been invented or found from other languages and incorporated into English. Similarly, old words and expressions have been discarded as their usefulness has diminished or the fashions have passed. This also happens to styles and modes of speech which became fashionable at a particular time and in specific circumstances.By the end of the 1960s it became apparent that it was not necessary to speak Standard English or even correct grammar to become popular, successful and rich. The fashionable speech of the day was no longer the prerogative of a privileged class but rather a defiant expression of class lessness.The greatest single influence of the shaping of the English language in modern times is the American English. Over the last 25 years the English used by many people, particularly by those in the media, advertising and show business, has become more and more mid-Atlantic in style, delivery and accent.In the 1970s, fashion favored stressless pronunciation and a language full of jargon, slang and “in” words, much of it quite incomprehensible to the outside world. What is considered modern and fashionable in Britain today is often not the kind of English taught in schools and colleges.1. Which one of the following is NOT true?2. What does the author imply by saying “there has been a considerable change of attitude towards speech snobbery” (Para. 3)?3. According to the author, there was a trend in the U.S. for the young people ______.4. The word “mid-Atlantic” in the passage (Para. 6) probably means ______.5. It can be concluded from the passage that ______.
