Question

【题目】______ he referred to in his article was unknown to the general reader.

A. ThatB. WhatC. WhetherD. Where

Answer 1

【答案】B

【解析】

考查主语从句。句意：他文章中提到的一般读者不知道。分析句子可知，_____ he referred to in his article 是主语从句，从句中referred to 缺宾语，其它选项都不能作宾语，that引导主语从句，无词义，不作成分，仅起引导作用，whether和where作状语。所以只能用What, 即：文章中所提到的（内容）。故选A。
