Question

(2013·蘇南四校3月聯(lián)考)Everybody knows about it now! But no one knows ________ once 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

Answer 1

B

句意：現(xiàn)在大家都知道它了。但沒(méi)人知道是什么曾經(jīng)阻止了謠言傳播。根據(jù)句意并分析句子成分可知，第二句為主從復(fù)合句，賓語(yǔ)從句是一個(gè)強(qiáng)調(diào)句，被強(qiáng)調(diào)的部分是主語(yǔ)，故用what。賓語(yǔ)從句中的語(yǔ)序應(yīng)用陳述語(yǔ)序，故答案為B。
