Question

任务型阅读 　　Space is a dangerous place not only because of meteors(流星), but also because of rays from the sun and other stars．The atmosphere acts as our protective blanket on the earth．Light gets through and this is essential for plants to make the food we eat．Heat also makes our environment endurable．Various kinds of rays come through the air from outer space． 　　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 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 organs may be damaged and this will not be discovered until the birth of deformed(畸形的)children or even grandchildren．Members of the Apollo flights had to cross belts of high radiation and during the outward and return journeys, the Apollo crew accumulated a large amount of radiation．So far, no dangerous amounts of radiation have been reported, but the Apollo members have been quite short．We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory．Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far． 　　Something is better than nothing．聊胜于无。L 阅读短文，并根据文章内容，判断下列句子的正确的用“T”表示，错误的用“F”表示。 (1) The atmosphere would prevent light that plants need． (　　) (2) The greatest danger to explorers in space is meteors． (　　) (3) The harm of radiation may be seen after a long period． (　　) (4) Members of the Apollo flights got lots of radiation in outer space． (　　) (5) The harm radiation had done to the Apollo members seems unknown． (　　) (6) The damage done by radiation can’t be decreased by drugs right now． (　　)
