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 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（畸形的） 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（积累） 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 don’t know yet how men are going to get on when they spent 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．
1．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（充分的） light for plant growth．
C．it supplies the heat necessary for human survival．
D．it screens off the falling meteors．
2．We know from the passage that___________．
A．exposure（揭露） to even tiny amounts of radiation is fatal（致命的） ．
B．the effect of exposure to radiation is slow in coming．
C．radiation is avoidable in space exploration．
D．astronauts in spacesuit needn’t worry about radiation damage．
3．The harm radiation had done to the Apollo crewmembers ___________．
A．is insignificant（不重要的） B．seems overestimated
C．is enormous D．remains unknown
4．It can be inferred from the passage that ___________．
A．the Apollo mission was very successful．
B．protection from space radiation is no easy job．
C．astronauts will have deformed children or grandchildren．
D．radiation is not a threat to well-protected space explorers．
5．The best title for this passage would be __________．
A．The atmosphere and Our Environment
B．Research on Radiation
C．Effects of Space Radiation
D．Importance of Protection Against Radiation

The House Committee(委员会)on Pollution(HCP)held a special meeting last night to discuss the Albanian case. A difficult situation came to notice last week after the Albanians had refused to allow an international environmental organization to test cans of industrial waste that they were throwing into the Sea of Japan. It was thought that the cans may have contained nuclear waste, even though the Albanians had strongly refused to admit this.
Six crew members from the Greenpeace ship “Tiger 2”, which is still closely monitoring(监视)the Albanian ship, secretly went aboard at night and took away one of the waste cans. The fist test results of the waste in the can suggested nuclear waste rather than other industrial waste according to a report from the Japanese laboratory where the tests are being carried out. Further tests are necessary to establish(确定)the exact level of nuclear content.
The Greenpeace action has made the Albanians a little angry but the Foreign Secretary here has insisted that the Albanian ship leave the Sea of Japan and return home immediately. They Albanians, not surprisingly, have refused to do so, and demanded that “Tiger 2” be called off from watching them.
The international community is suggesting that the Albanian ship be properly searched and are saying that it is very important and necessary that no more cans are dumped until the truth of this matter is made clear. Obviously, the Japanese government is particularly anxious to discover exactly what is being dumped so close to their northern islands, possibly polluting their fishing industry and putting people's lives in danger. The international community is to meet with the Albanian government tomorrow for the third time in a week.
