Question

【题目】For average parents in China, ________ is generally agreed that the education of their young is their primary concern.

A. it B. that

C. what D. which

Answer 1

【答案】A

【解析】句意：在中国，对于普通的父母来说，大家都同意子女的教育问题是他们最关心的事。本题考查it的用法。分析句子结构可知，空格处作的是主语，而后面that引导的从句又为真正的主语，所以应用it作形式主语，只有it才可以作形式主语。
