Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their space suits or the walls of their spacecraft, if they are inside, do prevent a' lot of radiation damage.
Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem". Scientists have reason to think that a man can put up with far more radiation than 0. 1 rem without being damaged, the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage--a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed children or even grandchildren Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months.
According to the first paragraph, the atmosphere is essential to man in that ______.
A.it protects him against the harmful rays from space
B.it provides sufficient light for plant growth
C.it supplies the heat necessary for human survival
D.it screens off the falling meteors
Kellerman: Obviously, certain children are brighter than others, but it’s not as simple as that. A lot of emphasis is placed on intelligence measured by tests.
Brigid: The so-called IQ tests?
Kellerman: Yes, Basically they are intended to test linguistic and numerical skills, so some children are bound to suffer. This is very unfortunate. A child with an average IQ may turn out to be successful when he grows up.
Brigid: What you' re saying is that some children have abilities that are not easy to measure, that aren’t appreciated.
Kellerman: Precisely. And if these skills are not spotted sufficiently early, they cannot be developed. That’s why, in my view, there are so many unhappy adults in this world. They are not doing the things they are best at.
Brigid: I see.
Kellennan: But at school, only those children who are good with words and numbers can do well in school examinations.
Brigid: Right. Is there anything a parent can do to help in this case?
Kellerman: Yes. In my opinion, a child should be judged on his individual talents. After all, being happy in life is put ting your skills to good use, no matter what they are.
What is the basic purpose of IQ tests?
A.They are designed to measure children's intelligence.
B.They are intended to test linguistic and numerical skills.
C.They are designed to test why some children perform. better at school.
D.They are intended to find out why some children are not appreciated.
A.They don’t have proper education.
B.They don’t have enough encouragement.
C.Their parents are not responsible.
D.They are not good with words and numbers.
However, this small amount of fresh water is still enough for us. But our need for water is increasing rapidly. Only if we take steps to deal with the problem now can we avoid a severe world-wide water shortage later on.
One of the first steps is to develop ways of reusing it. Today water is used only once and then discharged into a sewer system, and it eventually returns to the sea or runs into underground storage tanks. But it is possible lo pipe used water to a purifying plant. There it can be filleted and treated with chemicals so that it can be used again.
But even if every large city purified and reused its water, we would still not have enough.
All we'd have to do to make use of the sea water in, the world is to remove the salt. If we take these steps we'll be in no danger of drying up!
How much of the earth’s water can man really use?
A.He can use nearly 75% of it.
B.He can use about 97% of it.
C.He can use exactly 3% of it.
D.He can use less than 3% of it.
