There was one thought that air pollution affected only the area immediately around large c

ities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. (76)On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a "greenhouse effect"—conserving heat reflected from the earth and raising the world' s average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.

(77) Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth' s temperature—a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top fanning areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world' s temperature will stay about the same as it is now.

As pointed out at the beginning of the passage, people used to think that air pollution ______.

A．caused widespread damage in the countryside

B．affected the entire eastern half of the United States

C．had damaging effect on health

D．existed merely in urban and industries areas

第3题

Americans are proud of their variety and individuality, yet they love and respect few thin

gs more than a uniform, whether it is the uniform. of an elevator operator or the uniform. of a five-star general. Why are uniforms so popular in the United States？

Among the arguments for uniforms, one of the first is that in the eyes of most people they look more professional than civilian(百姓的) clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears a uniform. tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse, a policeman, a barber, or a waiter to lose professional identity(身份) than to step out of uniform？

Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are tax-deductible(可减税的). They are often more comfortable and more durable than civilian clothes.

Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms, the wearer of any particular type is generally stuck with it, without change, until retirement. When people look alike, they tend to think, speak, and act similarly, on the job at least.

Uniforms also give rise to some practical problems. Though they are long-lasting, often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain, requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes.

It is surprising that Americans who worship variety and individuality______.

A．still judge a man by his clothes

B．hold the uniform. in such high regard

C．enjoy having a professional identity

D．will respect an elevator operator as much as a general in uniform

第5题

One of the qualities that most people admire in others is the willingness to admit one's m

istakes. It is extremely hard sometimes to say a simple thing like "I was wrong about that," and it is even harder to say, "I was wrong, and you were right about that."

I had an experience recently with someone admitting to me that he had made a mistake fifteen years ago. He told me he had been the manager of a certain store in the neighborhood where I grew up; and he asked me if I remembered the egg cartons (in many countries, eggs are sold by the dozen and are put in cartons). Then he related an incident(event, matter)and I began to remember unclearly the incident he was describing.

I was about eight years old at the time. I went into the store with my mother to do some shopping. On that particular day, I must have found my way to the food department where the incident took place.

There must have been a special sale on eggs that day because there were lots of eggs in dozen and half-dozen cartons. The cartons were put three or four feet high. I must have stopped in front of the piles of egg cartons. Just then a woman came by pushing her shopping cart and knocked off the cartons. For some reason, I decided it was up to me to put the eggs back together, so I went to work.

The manager heard the noise and came rushing over to see what had happened. When he appeared, I was on my knees looking at some of the cartons to see if any of the eggs were broken, but to him it looked as though I was the one who just did it. He severely reprimanded me and wanted me to pay for any broken eggs. I tried to explain, but it did no good. Even though I quickly forgot all about the incident, it is plain that the manager did not.

According to this passage, many people will have a good opinion of those who ______.

A．have never made any mistakes

B．often make mistakes but correct them in no time

C．admit their mistakes

D．forget other people's mistakes easily

第6题

Cultural differences in business entertaining include issues such as whom one entertains a

nd where and how one entertains. In countries in which status is important, it is not advisable to invite people of different statuses to the same dinner party. Americans will often invite people to their homes. While in some societies the home is considered too private, unworthy, or embarrassingly small to serve as an appropriate forum for business entertaining. In some countries there is a " help yourself " approach to entertaining done in the home. This approach does not work well when entertaining people whose culture teaches them to wait to be asked three times before accepting an offer of food. In one instance, a Chinese guest went an entire evening without eating though he was quite hungry because he was too embarrassed to take food after only being asked to do so once. In another case, an American woman executive was being entertained at tea in London. After having the tea served, the American woman helped herself to cream and sugar rather than waiting to be served. The English woman was embarrassed by the implication that she was not serving quickly enough.

As a general rule, a small gift from your home country is appreciated. A gift that is tied to the particular interest of the individual is especially appreciated. Gifts for children are also well received. Be careful that the "hometown" gift you are bringing to Singapore was not made in Hong Kong. Because many gifts carry symbolic meanings, it is always best to seek the advice of a cultural informant before selecting gifts. The giving of large gifts, or payments for special service, should only be undertaken after consulting the legal department in the home and host culture.

It is no good inviting people of different social positions to the same party in the country where ______.

A．people don't pay any attention to your positions

B．people care much about their statuses

C．entertainment is important

D．entertainment is not advisable

根据以下材料回答第 36～40 题： Passage TwoDuring the Christmas shopping rush in London

根据以下材料回答第 36～40 题：

Passage TwoDuring the Christmas shopping rush in London, the interesting story was reported of a tramp (流浪者)who, apparently though no fault of his own, found himself locked in a well-known chain store late on Christmas Eve. No doubt the store was crowded with last-minute Christmas shoppers and the staff were dead beat and longing to get home. Probably all the proper security checks were made before the store was locked and they left to enjoy the three-day holiday untroubled by customers desperate to get last-minute Christmas presents.

However ridiculous that may be, our tramp found himself alone in the store and decided to make the best of it .There was food , drink ,bedding and camping equipment, of which he made good use. There must also have been television sets and radios. Though it was not reported if he took advantage of these facilities, when the shop reopened he was discovered in bed with a large number of empty bottles beside him. He seems to have been a man of good humor as indeed tramps very commonly are.

Everyone else was enjoying Christmas, so he saw no good reason why he should not do the same. He yielded himself cheerfully, and was taken by the police. Perhaps he had had a better Christmas than usual . He was sent to prison for seven days. The judge awarded no compensation (赔偿)to the chain store for the food and drink our tramp had consumed. They had , in his opinion, already received valuable free publicity from the story revealed in the newspaper and one television. Perhaps the judge had had a good Christmas, too.

第 36 题 The tramp was locked in the store_________.

A．for 7 days

B．on purpose

C．by accident

D．for security reasons

根据以下内容回答下列各题, Banks are not ordinarily prepared to pay out all accounts; they

rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced． One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived． The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand． The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers windows, The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same. A bank run happens when _______.

A.a bank is closed for one or more days

B.too many depositors try to draw out their money at one time

C.there is not enough money to pay all its depositors at one time

D.tellers of a bank take their own money from the bank
