A

As the first report of the accident came in, Burton was sitting in his office on the top floor of the building. Immediately ,realizing the seriousness of the whole incident, he moved to a ground floor room with a small waiting-room to look into the matter himself, leaving his second ?in ?com-man to take over all other cases.

He interviewed the first witness （證人）almost at once, making sure that everything was done that could be done to put him at his ease. However, the witness was obviously nervous and Burton took great pains to go over what he said thoroughly, hoosing and checking each word carefully and taking the man’s statement down himself.The witness had called the police and he’d waited until the ambulances began to arrive then when the first police car arrived on the scene he’d been asked to report to the station which was what he had done.

Burton explained that regrettably it would be necessary for him to go to court because of the serious nature of the disaster. More he could not say at present. He’d be thankful if the man could keep in touch with the police.

When he had gone, Burton put his head in his hands and considered before asking for the next witness. The man couldn’t be regarded as a hundred percent witness because he had been behind a wall when the explosion occurred. But in spite of his nerves, Burton had the impression that he was dependable, not afraid of relating himself to it and a fairly exact observer.

Well there would be other descriptions and no doubt all these would be put into place and the whole picture would become clear. He raised his head and pressed the bell on his desk.

“Next witness please,” he said.

56．Why did Burton move to the ground floor when he heard of the incident ?

A．Because the ground floor room had a small waiting ?room.

B．Because it would be easier for him to interview the witnesses.

C．Because he was not pleased to work on the top floor.

D．Because it would be easier for him to talk with the people.

57．How did the witness feel during the interview ?

A．Obviously somewhat frightened. B．Excited at seeing the incident.

C．Anxious to give a report to the police. D．Calm and unhurried.

58．The underlined part “ a hundred percent witness ”most probably means .

A．a(chǎn) patient and talkative person B．a(chǎn) well-informed witness

C．the only person who was interviewed in the incident

D．a(chǎn) person who watched the whole incident

59．Burton’s final impression of the witness was that .

A．his report was not clear though he was honest

B．he was afraid of being involved and refused to help the police

C．his observation was good but he was not very clear-headed

D．he was a dependable and reasonable witness

B

The problem of leisure is new. Until very recent times people worked each day to the limit of their strength. Of course there were always a privileged (有特權(quán)的)few who had leisure; but most men had to work 12, 14, or even 16 hours a day, six days a week. As late as 1840 the average factory worker labored 72 hours a week. "Sunup to sundown" was the farmer's day, or as another phrase puts it, "from can to can't."
　　Today, working less than a 40-hour week, people enjoy more leisure time. Therefore, the wise use of leisure time has become an important problem for everyone, young or old. It is a particularly difficult problem for the sick, the aged, and those who have retired from earning a living. Those people have so much leisure that it is hard for them to find interesting and worthwhile ways to use it .
　　However short the work week becomes, work is still the most important part of life. We do not work to get leisure and the pleasures leisure brings us; rather, we use leisure wisely so that work itself can become awarding and enjoyable. The feeling of success at doing one's daily work―whether it is a job, maintaining a home, or going to school―depends largely on coming to it each day with fresh energy and active interest.
　　Leisure and recreation (消遺)go together, though they are not necessarily the same thing. "Recreation" has an obvious meaning. It is the kind of leisure activity that brings "re-creation" of strength and spirit. When one speaks of making good use of leisure, he means choosing recreational activities which contribute to health, growth, and spirit.

60.How to spend leisure time wisely is not a particularly difficult problem for people _______.
　　 A. who are very busy everyday
　　 B. who are sick in bed
　　 C. who are aged and in good health
　　 D. who have retired from work
61.It can be inferred from the passage that _________ .
　　 A. we work hard so that we can enjoy more leisure.
　　 B. we enjoy leisure so that we can come back to work with energetically.
　　 C. Leisure can bring us a lot of pleasures that work can not.
　　 D. The success of work has little to do with how we spend our leisure time.
62. What is the relationship between leisure and recreation, according to the author?
　　 A. Leisure and recreation are closely related.
　　 B. Leisure and recreation are the same.
　　 C. Recreation covers all kinds of leisure activities.
　　 D. Recreation does not belong to any leisure activity.
63. From the passage we know that __________.
　　 A. leisure has been an old problem since ancient times
　　 B. leisure can not be replaced as the most important part of life
　　 C. our success in work is mostly determined by whether we use leisure wisely
　　 D. good recreational activities can help improve health, growth and spirit

C

Buy now, pay later. Credit cards give people that choice. Those billions of small pieces of plastic in use all over the world make it easy to buy things. But people who use credit cards unexpectedly can soon find themselves heavily in debt.
      Cardholders may not think about it, but they borrow money from a bank or other lender each time they charge something. They avoid interest charges if they pay their bill in full each month. But if they only make the minimum payment, the lowest required, it may take years to pay off a debt. Interest is continually charged on the unpaid amount of money.
     A credit card may have a number of costs. First, there is the interest charge on purchases, known as the annual percentage rate, or A.P.R. In the United States right now, the average is between thirteen and fourteen to keep them. Cardholders may have to pay cash advance fees if they withdraw (取) money from a credit card. There are also fees if they go over their credit limit, or if a payment is late. Lenders may also raise interest rates as punishment.
      In the United States, credit card fees have become a political problem. Congress has threatened (威脅) to take action against what critics call abusive behavior by lenders. Yet getting a credit card has become a lot easier for most people. Maybe too easy: People receive offers in the mail of pre-approved cards that they never asked for. Many cards offer low rates at first, especially if people agree to move their balance from another card, absolutely for free.
       About half of all Americans have at least two credit cards. And the credit rating agency Experian says fourteen percent of the population has more than ten. Jeanne Hogarth at the Federal Reserve, the central bank, says the average family has four credit cards. But families that carry a balance, meaning they do not pay off their statements each month, have an average of five.
      In 1988 Americans had three hundred thirty billion dollars in credit card debt. Last year it was eight hundred forty billion. In the latest government study, the average credit card debt for all households was more than three thousand dollars. But for those that carried a balance, the average was five thousand three hundred.

64. Credit cardholders can prevent themselves from paying interest charges by ______.
A. putting more money into the bank                B. paying cash advance fees
C. paying their bill in full each month                D. making the minimum payment
65. Which of the following is NOT included in the costs of a credit card?
A. A.P.R                                         B. Going over the card limit.
C. Late payment.                               D. Moving balance from another bank.
66. We can infer from the text that _______ is/are seriously concerned about what some lenders are doing with their credit cards.
A. the Federal Reserve                          B. cardholders
C. Congress                                       D. the credit rating agency Experian
67. Which would be the best title for this passage?
A. Credit Cards Are Easy to Get, But Harder to Pay Off     B. What Are Credit Cards
C. How to Apply for Credit Cards                               D. Say No to Credit Cards

I'm usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that today's children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children aged 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.
    Why are America's kids so stressed? The report mentions two main causes: increasing physical isolation ―brought on by high divorce rates and less involvement in community, among other things ―and a growing feeling that the world is a more dangerous place.
   Considering that we can't turn the clock back, adults can still do plenty to help the next generation deal with it.
    At the top of the list is nurturing develop a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.
    To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.

Limit the amount of virtual(虛擬的) violence your children are exposed to. It's not just video games and movies; children see a lot of murder and crime on the local news.
Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.
Make exercise part of your daily routine. It will help you deal with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesn't have to ruin your life.

Many cities around the world today are heavily polluted．Careless methods of production and lack of consumer demand for environment friendly products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.
      However, today, more and more consumers are choosing “green” and demanding that the products they buy should be safe for the environment. Before they buy a product, they ask questions like these: “Will this shampoo damage the environment?” “Can this metal container be reused or can it only be used once?”
      A recent study showed that two out of five adults now consider the environmental safety of a product before they buy it. This means that companies must now change the way they make and sell their products to make sure that they are “green”, that is, friendly to the environment.
     Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels to show that the product is green. Some companies have made the manufacture of clean and safe products their main selling point and emphasize it in their advertising.
     The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of “Buy it, use it, throw it away, and forget it”. The public pressure is on, and gradually business is cleaning up its act.

Inflation refers to a rise in prices that causes the purchasing power of a nation to fall. Inflation is a normal economic development as long as the annual percentage remains low; once the percentage rises over a pre-determined level, it is considered an inflation crisis.

There are many causes for inflation, depending on a number of factors. For example, inflation can happen when governments print too much money to deal with a crisis. As a result, prices end up rising at an extremely high speed to keep up with the extra money. This is called the demand-pull, in which prices are forced upwards because of a high demand.

Another common cause of inflation is a rise in production costs, which leads to an increase in the price of the final product. For example, if raw materials increase in price, this leads to the cost of production increasing, which in turn leads to the company increasing prices to maintain steady profits. Rising labor costs can also lead to inflation. As workers demand wage increases, companies usually chose to pass on those costs to their customers.

Inflation can also be caused by international lending and national debts. As nations borrow money, they have to deal with interests, which in the end cause prices to rise as a way of keeping up with their debts. A deep drop of the exchange rate can also result in inflation, as governments will have to deal with differences in the import/export level.

Finally, inflation can be caused by federal taxes put on consumer products such as cigarettes or fuel. As the taxes rise, suppliers often pass on the burden to the consumer; the catch, however, is that once prices have increased, they rarely go back, even if the taxes are later reduced. Wars are often cause for inflation, as governments must both pay back the money spent and repay the funds borrowed from the central bank. War often affects everything from international trading to labor costs to product demand, so in the end it always produces a rise in prices.
