　　1. B

　　文章主要讲述了救生衣的设计。间接题型段首主旨题。C项和D项都是对救生衣设计中设计材料的说明。A项为陷阱，指救生衣的用途，尽管开头提到，但范围不着边际。故只有B是正确选项。

　　2. D

　　根据文章，救生衣首先会自动扶正。事实细节题。本文第三段主要讨论救生衣落水位置，应设计的能“自动扶正”,或稍向后仰。B项是对材料的描述，范围太窄，而A和C不合题意，因此D是正确答案。

　　3. C

　　美国海岸巡逻队不需要救生衣根据穿戴者的尺寸生产。事实细节题。A项和B项都涉及method，其相关部分见最后一段第三句，A，B，D三项都是文章中提及的，C项与本题无关的内容，因此应该选C。

　　4. A

　　“the uninitiated individual”作者指的是不知道怎么使用救生衣的人。语义指代题。根据文章最后一段第一句，我们可推出“the uninitiated individual”就是指的那些不知道怎么使用救生衣的人。故A是正确选项。

　　5. D

　　如果一个人没有正确使用救生衣，就会发生什么?细节辨别题。第三段第一句后半句中a face-down position和本题中的 in a wrong position相对应。因此选项D“他可能太累了或者是已经失去知觉”是正确答案。
