题目解析
【分析句子结构及考点分析】该句考查的是介词+关系代词构成的定语从句,是升本考试中的高频考点【难】,在往年真题中都有考查。
介词+关系代词结构中:
关系代词的选择:介词+which指物;介词+whom指人。
介词的选择:根据从句中动词词组或形容词词组的固定搭配来选择介词。
题中have confidence in sb. 是固定搭配,先行词chairman指人,所以选项B为正确答案。
【分析其他选项】
选项A介词搭配错误;
选项C介词搭配错误,注:该选项中介词并没有放在关系代词之前,此时关系代词who或whom都可;
选项D介词搭配错误。
知识梳理
定语从句通常有以下作用:
①修饰和限定名词;
②连接两个具有共同名词的句子;
③表示因果逻辑关系。
我们把题目中介词+关系代词的句子看成第②种作用,把句子拆分成通过关系词连接两个句子,即:
we need a chairman.
Everyone has confidence in the chairman.
此时合并两句话,将重复的名词用指人的关系代词whom来取代,
we need a chairman in whom everyone has confidence in.
再举个例子:
The factory produces half a million pairs of shoes every year, 80%_____are sold abroad(国外).
A. of which; B. which of; C. of them; D. of that
此句拆分为:
①Thefactory produces half a million pairs of shoes every year.
②80% of the shoes are sold abroad.
直接将第二句的名词the shoes替换成关系代词which,正确答案为A。
