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)
Resuks of the tests suggest that wmen will have significant advantage over men in space.(5)Men’s advantages in terms of strength and stamina, meanwhile, are virtually wiped: out by the zero gravity condition in space.

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.

选项
答案C
解析 空格前面没有明显的篇章词汇，从前句中的核心结构来看“有三组美国妇女参加了长达一个月的以太空旅行为目的的测试”，结合下一句(第2段第1句)该句说“这些妇女是从许多申请者中仔细挑选出来的”，下一段的中心是围绕妇女展开(从下一段中句子的核心结构町以看出)因此判断第 1段的主题应该涉及到实验更合理，因此判断C是答案。提示：抓住段蒋中心确认段落中旬于的语意特点。
