一道英语选择题。麻烦学者讲一下。

1.when his house was broken 定语状语从句；
2. it 表时间，又如： It is Sunday today.
3.他何时遇见他的？---在他家被贼光顾的那一天。

这是一个易错题，考查的其实不是强调句。因为强调句去掉that依然成立。本句话去掉that就变为his house was broken into on the day，是不是不通呢？

答案 B
这是一个省略的强调句型，完整的应该是
It was on the day when his house was broken into that I met him.强调状语 on the day 同时the day 后带定语从句when his house was broken into
