A At the end of ten years, they had to spend a further twenty days absolutely confined to bed.
B They were volunteers and were paid barely above the minimum wage.
C These tests were conducted to determine how they would respond to conditions resembling those abroad the space shuttle.
D They need less food and less oxygen and they stand up to radiation better.
E Some of them were over 65.來源：考試大
F When they were finally allowed up, the more physical active women （揭示前面的they指的是“女性”）were specially subject to pains due to a slight calcium (鈣)loss
Between 1977 and 1981, three groups of American women, numbering 27 in all, between the age of 35 and 65, were given month-long tests for space travel purposes. __1__.
Those women were carefully selected from among many applicants. __2__. They were not allowed to smoke or drink alcohol during the tests, and they were expected to tolerate each other’s company at close quarters for the entire period. Among others things they had to stand pressure three times the force of gravity and carry out both physical and mental tasks while exhausted from strenuous physical exercise. __3__. During that time they suffered backaches and other discomforts. __4__.
1．C。分析：空格前面沒有明顯的篇章詞匯，從前句中的核心結(jié)構(gòu)來看“有三組美國婦女參加了長達(dá)一個月以太空旅行為目的的測試”，結(jié)合下一句（第2段第1句）該句說“這些婦女是從許多申請者中仔細(xì)挑選出來的”，下一段的中心是圍繞婦女展開（從下一段中句子的核心結(jié)構(gòu)可以看出）因此判斷第1段的主題應(yīng)該涉及到實(shí)驗更合理，因此判斷C是答案。

空格2，空格3和空格4在同一段落中所以可以同時考慮：因為它們應(yīng)該圍繞一個中心，一個主題發(fā)展。段首句說“這些婦女是從許多申請者中仔細(xì)挑選出來的”，而空格4就是該段的結(jié)尾，第4空格的前句說“在那段時間期間，…”, that time 暗示前面一定有明確的時間詞，但是在空格3的前句中沒有發(fā)現(xiàn)這樣時間詞，所以只能是空格3涉及到時間，因此判斷A是空格3的答案。而空格3的含義是“參加實(shí)驗的婦女有20天的時間都被要求躺在床上”，對比被選項發(fā)現(xiàn)F應(yīng)該是空格4的答案：F中的“最終戰(zhàn)立起來”與“躺在床上”呼應(yīng)，而且空格4的前句說的是婦女感受到的不適，而F也是相似的內(nèi)容，因此判斷F是答案；對于空格2，因為空格前句中是在對這些參加實(shí)驗的婦女進(jìn)行介紹，因此判斷B合適：D在空格前后句中沒有比較的對象，E不合理
D They need less food and less oxygen and they stand up to radiation better.
E Some of them were over 65.來源：考試大
Results of the tests suggest that women will have significant advantage over men in space. __5__. Men’s advantages in terms of strength and stamina（毅力）, meanwhile, are virtually wiped out by the zero-gravity condition in space.
5． D。 空格前后句都出現(xiàn)了“優(yōu)勢”，是在進(jìn)行比較，因此判斷D是答案。
