柳成回答：

　　1.D细节理解题。由题目中的关键词thedoctorstestfirst可回原文定位于第二段。根据第二段第一句"Thefirsttestisfortheheart."可知，对宇航员的身体检查第一项就是对心脏功能的检查。2.D细节理解题。由题目中的关键词howlong...stayinthebaginthetestbecause可回原文定位于第三段。让宇航员待在一个布袋里进行测试而不告诉他要待多长时间的原W是，万一航天飞机发生故障宇航员就得进人这样一个封闭的袋子里等待救援，他们并不知道要等多长时间，要让自己适应在这种黑暗和狭小的空间里生存待援。3.A细节理解题。由题目中的关键词don'tlearnhowto可回原文定位于第四段。通读该段可知，在太空中走和跑不是宇航员在训练中心所训练的项目。4.C细节理解题。由题目中的关键词thecorrectorder可回原文定位并理解全文。通读全文可知，正确的顺序是:宇航员进人训练中心；医生进行测试;选择最好的人进行训练;宇航员学习关于太空旅行的新知识;宇航员开始工作。5.B细节理解题。由题目中的关键词NOTtrue可回原文定位于全文。根据最后一段第二、三句机组人员在开始工作前才互相认识，因此B项表述"机组人员测试后相互认识"是错误的。
