What will man be like in the future-in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today. For man is slowly changing all the time.

   Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change to the head, in particular the forehead, will grow larger.

   Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man's eyes will grow stronger.

   On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.

   But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.

   Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with use. He will still be a human being, with thoughts and emotions similar to our own.

71. The passage mainly tells us that ________.

　　A. man's life will be different in the future

  　B. future man will look quite different from us

    C. man is growing taller as time passes

　　D. man will disappear

72. What serves as the evidence（证据）that man is changing?

　　A. Man has got stronger eyes now than he ever had.

　　B. Man's hair is getting thinner and thinner.

　　C. Man's arms and legs have become lighter and weaker.

　　D. Man has been growing taller over the past 500 years.

73. The change in man's size of forehead is probably because ________.

　　A. he makes use only 20 % of the brain's capacity

　　B. his brain has grown larger over the past centuries

　　C. the other 80% of his brain will grow in due time

　　D. he will use his brain more and more as time goes on

74. What is true about a human being in the future?

　　A. He is hairless because hair is no longer useful.

　　B. He has smaller eyes and wears better glasses.

　　C. His fingers grow weaker because he doesn't have to make use of them.

　　D. He thinks and feels in different way.

75. We can infer that _______.

　　A. human beings will become less attractive in the future.

　　B. less use of a bodily organ may lead to its becoming worse

　　C. human beings hope for a change in the future life

　　D. future life is always predictable

　　The traditional dream of Chinese philosophers to be able to “run with the wind” became a reality this New Year's Eve day.

　　The Shanghai Transrapid Maglev Line(首次) test run and the first commercial maglev (magnetic levitation) system in the world was put to use.

　　The project is a joint effort by China and Germany. It cost 10 billion yuan and took two and a half years to complete.

　　The maglev train ran smoothly, building up speed to 427 kilometres per hour. It covered a 45-minute journey by car in an easy eight minutes. However, the short trip costs as much as 50 yuan. There are speculations(推测) that within ten years there could be a line from Shanghai to Beijing－1280 kilometres. The journey would only take three hours. The total cost of the maglev would be about US $ 24 billion.

　　Unlike the current railway system with traditional tracks, the maglev runs on magnetic levitation lines. The powerful electric current enables the fast train to rise above the line and float.

　　A maglev system can reach speeds of up to 400～500 kilometres per hour, much faster than any normal railway system. The lack of contact between the train and the maglev “tracks” reduces the noise level and the damaging effect on the land of a city.

　　The maglev system is also energy-efficient. Its energy consumption(消耗) is only about half that of cars and a quarter that of aircraft with the same transport capacity.

　　The effect of the magnetic force of the maglev system on passengers and nearby areas is minimal since the effect on humans is less than that of most electric household appliance(家用电器).
