题目内容
7.Scientists have advanced many theories about why human beings cry tears,none of ______ has been proved.( )A. | whom | B. | which | C. | what | D. | that |
分析 科学家们提出了很多关于人类为什么哭泣时流泪的理论,这些理论尚未得到证实.
解答 答案:B 本题考查的是关系代词的用法.whom指人,which指物,what什么(不能用在定语从句中),that既指人也可以指物(不能用在介词后),题干中关系词指代的是theories,并且位于介词后,故选B.
点评 定语从句中关系代词的选择要根据先行词和从句的结构来判定,同时还要注意短语从句是限制性还是非限制性(非限制性定语从句中不能用that).
