问题描述：
Our classroom is very clean.Do you know who__cleaned it?
A. was it that B. it was that C. was it who D.he was
这要用什么语序,是强调句吗
Do you know who it was that cleaned it？这个句子怎么分析
答
选B,该句中的宾语从句为强调句型.
Do you know who it was that cleaned it?
分析：此句的主句为 Do you know ...一般疑问句做主句时,从句是特殊疑问句的,将特殊疑问词提前后,问句语序恢复为正常语序.
所以强调句型 It was who that cleaned it 变为 who it was that cleaned it.
不知道这样讲,有没有明白?
