Part III Reading Comprehension (35 minutes)
Directions: There are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Passage One
Question 51 to 55 are based on the following passage:
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 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. Af soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their kspacecraft,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 (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high 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 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 beenfound so far.
51. According to the first paragraph, the atmosphere is essential to man in that ______.
A) it protects him against the haumful 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
52. We know from the passage that ______.
A) exposure to even tiny amounts of radiation is fatal
B) the effect of exposure to radiation is slow in coming
C) radiation is avoidable in space exploration
D) astronauts in spacesuits needn't worry about radiation damage
53. The harm radiation has done to the Apollo crew members ______.
A) is insignifiacant B) seems overestimated
C) is enormous D) remains unknown
54. 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
55. 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
