题目内容

In our class there are 46 students, ______ half wear glasses.

A.in whom          B.in them           C.of whom          D.of them

 

【答案】

C

【解析】

试题分析:考查定语从句:先行词是46 students,定语从句改成简单句应该是:half of the students wear glasses,所以用of whom引导定语从句,句意:我们班有46名学生,其中一半戴眼镜。选C。

考点:考查定语从句

点评:定语从句的考查主要就是考查关系词的辨析,关系代词that, which, whose, whom, as, who在句中做主语,宾语,表语或者定语;where, why, when在句中做状语。要分析句子成分,看缺少什么成分,就选用相应的关系词。如果定语从句中缺少介词,可以用介词+which/whom引导定语从句。
