Around the world more and more people are taking part in dangerous sports and activities. Of course, there have always been people who have looked for adventure -- those who have climbed the highest mountains, explored unknown parts of the world or sailed in small boats across the greatest oceans. Now, however, there are people who seek an immediate excitement from a risky activity which may only last a few minutes or even seconds. I would consider bungee jumping to be a good example of such an activity. You jump from a high place (perhaps a bridge or a hot-air balloon) 200 meters above the ground with an elastic rope tied to your ankles. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is estimated that two million people around the world have now tried bungee jumping. Other activities which most people would say are as risky as bungee jumping involve jumping from tall buildings and diving into the sea from the top of high cliffs. Why do people take part in such activities as these Some psychologists suggest that it is because life in modem societies has become safe and boring. Not very long ago, people’s lives were constantly under threat. They had to go out and hunt for food, diseases could not easily be cured, and life was a continuous battle for survival. Nowadays, according to many people, life offers little excitement. They live and work in comparatively safe environment; they buy food in shops; and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to seek danger in activities such as bungee jumping.A suitable title for the passage is （） A．Dangerous Sports; What and Why B．The Boredom of Modem Life C．Bungee Jumping: Is It Really Dangerous D．The Need for Excitement

There is a range of activities which require movements of about one to four or five miles. These might be leisure activities, such as moving from home to swimming pool, tennis club, the theater or other cultural centers, or to a secondary or more advanced school; or they might be movements related with work and shopping in the central areas of cities. The use of cars which are able to carry five people at 80 mph for satisfying these needs is wasteful of space and most productive of disturbance to other road users.The use of the bicycle, or some more modern derivative（派生的）of it, is probably worth more consideration than has recently been given to it. The bicycle itself is a remarkably efficient and simple device for using human muscular energy for transportation. In pure energy terms, it is four to five times as efficient as walking, even though human walking itself is twice as efficient as the movement of effective animals such as dogs. It is still widely used, not only in some developing countries where bicycles are major means of people and goods, but in a few richer towns such as Amsterdam in Holland and Cambridge in England.The bicycle neither gives enough protection from the weather nor is very suitable for carrying goods, and demands considerable muscular work to make progress against wind or uphill. It also offers its rider no protection against collisions with other vehicles. All these difficulties could, however, be greatly got rid of with relatively small changes in design. The whole machine could be enclosed in a plastic bubble（气泡）which would provide some protection in case of accidents.It would be easy to add a small petrol or electric motor. A wide variety of designs would be possible. As in rowing, we might employ the power of the arms or the general body musculature, as well as those of the legs; more muscular exercise would be good for the health of many people in cities, and a wide use of bicycle like muscle-powered vehicles would be a useful way to ensure this. It could also provide opportunities for showing-off by the young and vigorous. (1)The main idea of the first paragraph is that the car . A.can satisfy the demand for speed B.causes waste of space C.produces disturbance to other road users D.is far from perfect for short range movements (2)More attention should be given to the bicycle as a means of transport because it is . A.a very efficient and simple device B.much cheaper than a car C.widely used in Amsterdam and Cambridge D.still used by rich people (3)Enclosing the bicycle in a plastic bubble would . A.make it easier to use B.save muscular energy C.provide protection from the weather D.prevent it from crashing with other vehicles (4)Which of the following statements is UNTRUE for the present bicycle? A.It is far more efficient than the movement of animals. B.It offers its rider no protection. C.It is not very suitable for carrying goods. D.It can hardly be improved on.

Biological wizardry of a different sort is responsible for the ruggedness of sea-ear shells, which under high-powered microscopes resemble ______ constructed stone walls. A. reversibly B. elaborately C. spontaneously D. concurrently

In recent years many countries of the world have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the worker's life more enjoyable, it does not actually make him work harder. As far as increasing productivity is concerned, then variety is not an important factor. Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modem factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is usually very little that can be done to create it. Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines rather than one large one, so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of worker contribution an important factor, therefore, but it is also one we can do something about. To what extent does more money lead to greater productivity? The workers themselves certainly think this important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them. 1. Which of these possible factors leading to greater productivity is not true? A. To make jobs more varied. B. To give the worker freedom to do his job in his own way. C. Degree of work contribution. D. Demands for longer working hours. 2. Why do workers want more money? A. Because their jobs are too boring. B. In order to enjoy more spare time. C. To make their jobs more interesting. D. To demand shorter working hours. 3. The last sentence in this passage means that if we succeed in making workers’ jobs more interesting——. A. they will want more money B. they will demand shorter working hours C. more money and shorter working hours are important factors D. more money and shorter working hours will not be so important to them 4. In this passage, the author tells us——. A. how to make the workers more productive B. possible factors leading to greater efficiency C. to what extent more money leads to greater productivity D. how to make workers' jobs more interesting

阅读理解 　　CATV is a short way of saying“community antenna(社区天线)television”. But“cable television”is the term most people use. Cable television allows viewers to receive TV programs that they cannot pick up with their regular antennas. 　　Television signals do not follow the curve (曲线) of the earth. They travel in straight lines in all directions. Signals from a TV station move toward the horizon(地平线)and then go into space. If you live only a few miles from a station, you may not get any picture at all. 　　CATV began in 1948. People in places far from TV stations shared the cost of putting up high antennas. A community antenna was usually placed on a hill, a mountain，or on a high tower. The antenna picked up TV signals and fed them into a small local station. From the station, thick wires called cables ran out to nearby homes. Each person using the cable paid a monthly charge. 　　CATV worked well, and soon new uses were found for it. Local stations could feed programs into empty channels that were not in use. People along the cable could have local news, weather reports, and farm and school news at no extra charge. 　　Today, cable television has moved into cities. It brings in extra programs that city viewers with regular antennas cannot see. It is also used in many classrooms throughout the country. 1．From the first paragraph we know that _____.
