Nowadays, advertisements can be found everywhere in a big city such as Shanghai. They shout at us from the television screen and radio loudspeakers, wave to us from every page of the newspaper, signal to us from the roadside billboards all day and flash messages to us in colored lights all night. What do you think of the flood of advertising make any contribution to our society? For this part you are to write a composition on the topic If There Were No Advertisements. You should illustrate your viewpoints on advertisement in no less than 200 words.

In Chicago, a computerized system has beendeveloped that controls traffic in the city's seven onexpressways now, one man—a controller—can follow（1）the movement of Chicago's traffic as looking at a set of lights. （2）The system uses electronic sensors that is built into （3）each expressway, half a mile each apart. Several times （4）a second, the computer receives information for each sensor and translates it into green, yellow, or red lights（5）in a map in the control room.A green light means traffic is moving forty-five tosixty miles an hour, yellow means heavy traffic cars（6）stopping still or moving less than thirty miles an hour. “See that red light near Austin Avenue?” the controller（7）asked a visitor. “That’s a repair truck fix the （8）road, and the traffic has to go near it.”At the Roosevelt road entrance to the expressway,the light kept changing from green to red and back to（9）green also. “A lot of trucks gel on the expressway there.” the controller explained, “They can't speed（10）forward as fast as cars.” 60. forward——up .The sensors show immediately where an accident or astopped car is blocking traffic, and a truck is sent by radio to clear the road. The system has lowered accidents by 18 percent. There are now 14 deaths on Chicago’sexpressways for each one hundred million miles traveled, while nationally there are 26 .

Researchers have found that migrating animals use a variety of inner compasses to help them navigate. Some direct themselves by the position of the sun. Others navigate by the stars. Some use the sun as their guide during the day, and then switch tn star navigation by night. One study shows that the homing pigeon uses the Earth's magnetic fields as a guide in finding its way home, and there are indications that various other animals, from insects to mollusks, can also make use of magnetic compasses. It is of course very useful for a migrating bird to be able to switch to a magnetic compass when clouds cover the sun; otherwise it would just have to land and wait for the sun to come out again.Even with the sun or stars to guide by, the problems of navigation are more complicated than they might seem at first. For example, a worker honeybee that has found a rich source of nectar and pollen flies rapidly home to report. A scientist has discovered that the bee sent out to look for food delivers her report through a complicated dance to the other workers not only how far away the food is, but also what direction to fly in relation to the sun. But the sun does not stay in one place all day. As the workers start out to gather the toed, the sun may already have changed its position in the sky somewhat. In later trips during the day, the sun will seem to move farther and farther toward the west. Yet the worker bee seem to have no trouble at all in finding the food source. Their inner clocks tell them just where the sun will be, and they change their course correspondingly.1.The author mentions all the following natural phenomena that help animals navigate EXCEPT （）.2.What makes it necessary for a bird to rely on a magnetic compass when navigating?3.According to the passage what information does the dance of the scout bee communicate to the other worker bees?4.What enables the bees to fly by the sun even though the sun’s position is not fixed?

In the last 12 years total employment in the United States grew faster than at any time in the peacetime history of any country—from 82 to 110 million between 1973 and 1985—that is, by a full one third. The entire growth, however, was in manufacturing, and especially in non-blue-collar jobs.This trend is the same in all developed countries, and is, indeed, even more pronounced in Japan. It is therefore highly probable that in 25 years developed countries such as the United States and Japan will employ no larger a proportion of the labor force in manufacturing than developed countries now employ in farming—at most, 10 percent. Today the United States employs around 18 million people in blue-collar jobs in manufacturing industries. By 2010, the number is likely to be no more than 12 million. In some major industries the drop will be even sharper. It is quite unrealistic, for instance, to expect that the American automobile industry will employ more than one-third of its present blue-collar force 25 years hence, even though production might be 50 percent higher.If a company, an industry or a country does not in the next quarter century sharply increase manufacturing production and at the same time sharply reduce the blue-collar work force, it cannot hope to remain competitive—or even to remain “developed.” The attempt to preserve such blue-collar jobs is actually a prescription for unemployment.This is not a conclusion that American politicians, labor leaders or indeed the general public can easily understand or accept. What confuses the issue even more is that the United Stales is experiencing several separate and different shifts in the manufacturing economy. One is the acceleration of the substitution of knowledge and capital for manual labor. Where we spoke of mechanization a few decades ago, we now speak of “robotization” or “automation”. This is actually more a change in terminology than a change in reality. When Henry Ford introduced the assembly line in 1909, he cut the number of man— hours required to produce a motor car by some 80 percent in two or three years—far more than anyone expects to result from even the most complete robotization. But there is no doubt that we are facing a new sharp acceleration in the replacement of manual workers by machines—that is, by the products of knowledge.1.According to the author, the shrinkage in the manufacturing labor force demonstrates（） .2.American politicians and labor lenders tend to dislike（） .3.According to the author, in the coming 25 years, a developed country or industry, in order to remain competitive, ought to（） .4.This passage may have been excerpted from（） .

In general, our society is becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and “human-relations” experts; yet all this oiling does not alter the tact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue-collar and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more d matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the tight mixture of submissiveness and independence. From that moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along. etc. This constant need to prove that one is as good as or better than one's fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness.Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century “free enterprise” capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of love and of reason—are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.1.By “a well-oiled cog in the machinery” the author intends to render the idea that man is （）.2.From die passage we can inter that real happiness of life belongs to those（） .3.To solve the present social problems the author suggests that we should（） .4.The author's attitude towards industrialism might best be summarized as one of（） .

Complete silence is found only in laboratories called anechoic rooms. The walls and ceilings, made of blocks of special sound-sucking materials, are more than three feet thick, while floor coverings are six-foot layers of feathers or cotton wool. Silence here can be as painful to the ears as the din (continuous loud noise) of a steelworks or a rocket blast-off, yet scientists get used to this and stay in these silent rooms for hours at a time, using microphones and electronic equipment to test the various materials being developed to make the world a less noisy place.Architects have used scientific discoveries to solve noise problem in a number of ways. Walls are hollowed (having empty space inside) and then filled with sound-sucking materials similar to cotton wool. Extra-thick carpets cover the floors, and thick woolen curtains cover the windows. Air conditioning and heating channels are made less noisy by sound-sucking materials．Unfortunately, these techniques and others often work too well in some buildings. Noise-proof rooms become almost anechoic and people living in them are disturbed by the lack of sound．One way of handling this problem is to use what they call “sound perfume” — artificial (similarly produced, made by man) noise is piped to rooms through small loudspeakers.1.Scientists use anechoic room for（） .2.The writer implies that （） .3.People suffer in anechoic rooms probably because （） .4.The article suggests that （） .

An unidentified wit once said, “laugh, and the world laughs with you. Snore, and you sleep alone.” Yet snoring is far from a laughing matter, as those unfortunates with good hearing, who are rightly subjected to the sounds of the snoring disorder, will testify.It has been estimated that one of eight Americans snores: this means that there are approximately 21 million people—women as well as men—who render an unpleasant sound when they are asleep. And assuming that each snorer disturbs the sleep of at least one other person, it necessarily follows that there are 21 million unhappy listeners. While a sleeping person breathes, either in or out, several structures in his nose and throat generate the snoring. The sounds, coming from the soft palate and other soft structures of the throat, are caused by vibratory responses to inflowing and outflowing air. When the soft tissues of the mouth and throat come close to the lining of the throat, the vibrations that occur are caused by the position of the tongue. In short, the noise made by snoring can be compared to the noise when breezes flutter a flag on a pole. The frequency of the vibrations depends on the size, density, and elasticity of the affected tissues and on the force of the air flow. Although it is usually the process of in haling or exhaling through the mouth that cause snoring, short snorts come from the nose of an open-mouthed sleeper. In all fairness to snorers, however, it should be emphasized that snoring is an involuntary out which stops as the offender is awakened.1.The snoring is caused by （） .2.If a person produces short snores, most probably he has （） .3.The snorers can have control over their act.4.The author’s attitude towards the snorers is （） .
