Question

It was while she was sleeping in her bedroom ____ a thief broke into the house

It was while she was sleeping in her bedroom ____ a thief broke into the houseA. which            B. that             C. where            D. than 此句为强调句型，我觉得应选B，但答案是A，到底选哪个呢

Answer 1

正确答案是B，that。
分析：这个一个强调句，it is .....that(who)句型的考查。
选which 是因为以为这个一个定语从句，以为which引导的是修饰bedroom的定语，但其实不是。如果是定语的话，应该是这样：she was sleeping in her bedroom which a thief broke into ，后面就没有the house 啦！ the house 和 bedroom重复了

这个句子的原型是： a thief broke into the house while she was sleeping in her bedroom （把 it is ..that 去掉，剩下的仍然是一个完整的句子）
，为了强调小偷进去的时间，所以把while she was sleeping in her bedroom 放在it is 和that 的中间。

Answer 2

A.it……that强调句型。
