There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” “What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.
During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.
A. the feasibility of landing a satellite on Earth
B. the possibility of making a first-rate flying saucer
C. the feasibility of sending a Venus Being to Earth
D. the possibility of directing a flying saucer into Manhattan

A. they need it in their way to the planet of Earth
B. the Earth’s atmosphere is filled with deadly gases
C. there is a low level of oxygen for Venusians
D. there is no air on the planet of Earth

A. the polluted air hovering over the surface of Earth
B. the mass of tiny drops of water floating above Earth
C. the mass of small things moving through the air
D. the dark clouds gathering before a storm breaks
The author wishes to call our attention to the fact that ____.
A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this
B. that there is a point in spending billions to land a flying saucer on Earth
C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.

Have you ever been ill? When you are ill, you must be unhappy because your body becomes hot, and there are pains all over your body. You don’t want to work, and you stay in bed, feeling very sad.
What makes us ill? It is germs(细菌). Germs are everywhere. They are very small and you can’t find them with your eyes, but you can see them with a microscope. They are very very small and there could be hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall see them in it. So your father and mother will not let you drink dirty water.

查看习题详情和答案>>What will man be like in the future — in 5,000 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 a relatively short period of time, so we may assume 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 (容量). 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 too: 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 a 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 us. He will still be a human being, with thoughts and emotions similar to our own.
56. The size of man’s forehead will probably grow bigger because _______.
A. he will use his brain more and more as time goes on
B. he makes use only 20% of the brain’s capacity
C. his brain has grown larger over the past centuries
D. the other 80% of his brain will grow in due time
57. What serves as the evidence that man is changing?
A. Man has got stronger eyes now than he ever had.
B. Man has been growing taller over the past 500 years.
C. Man’s hair is getting thinner and thinner.
D. Man’s arms and legs have become lighter and weaker.
58. What will be true about a human being in the future?
A. He will be hairless because hair is no longer useful.
B. He will have smaller eyes and will wear better glasses.
C. His fingers will grow weaker because he won’t have to make use of them.
D. He will think and feel in a different way.
59. It is implied that __________________.
A. human beings will become more attractive in the future
B. body organs will become poorer if they are not used often
C. human beings hope for a change in the future life
D. future life is always predictable
60. The passage mainly tells us that _______________.
A. man’s life will be different in the future B. man is growing taller and uglier as time passes
C. future man will look quite different from us
D. human beings’ organs will function weaker
