问题选择题

Everybody knows about it! No one knows _________ prevented the rumor from spreading.

A．what was it that

B．what it was that

C．how it was that

D．why it was that

答案

答案：B

题目分析：考查强调句的特殊疑问句做宾语从句：强调句的特殊疑问句结构为：疑问词＋is/was it that...？因为是做宾语，所以语序是陈述句语序，句意：每个人都知道，没人知道是人们阻止谣言传播的。选B。

点评：强调句型特殊疑问句的基本结构为：疑问词is/was it被强调成分that/who其它成分；其最大的特点是把it is/was…that/who…去掉以后句子仍然成立。这里做宾语从句时要变成陈述句语序。
