Not long ago it was assumed that the dangers man would meet in space would be terrible, the main ones being radiation and the danger of being hit by meteors. It is perhaps worth remembering ’that less than two centuries ago the dangers of train travel seemed similarly terrible. A man would certainly die, it was thought, if carried along at a speed of thirty kilometers per hour.
There are two sorts of radiation man must fear in space. The first is radiation from the sun, and this is particularly dangerous when the sun is very active and explosions are occurring on its surface. The second, less harmful form comes from the so-caned Van Allen Belts. There are two areas of radiation about 1 500 miles away from the earth. Neither of these forms of radiation area danger to us on the earth, since we are protected by our atmosphere. Specifically, it is that part of our atmosphere known as the ozonosphere which protects us. This is a belt of the chemical ozone between 12 and 21 miles from the ground, which absorbs all the radiation.
Once outside the atmosphere, however, man is no longer protected, and radiation can be harmful in a number of ways. A distinction must be drawn between the short-and long-term effects of radiation. The former are merely unpleasant, but just because an astronaut returning from a journey in space does not seem to have been greatly harmed, we cannot assume that he is safe. The long-term effects can be extremely serious, even leading to death.

D、We cannot assume that an astronaut is safe from his good looks.
答案

解析
What can we infer from the passage?
四个选项都是关于宇航员从太空返航的,由此可以推测,本问题的考查内容可能与宇航员有关。
文中关键句为...an astronaut returning from a journey in space does not seem to have been greatly harmed, we cannot assume that he is safe. 即使宇航员看起来状态并不像受过严重损伤,也不能认为他是很安全的。故正确答案为D)。
