it was she who cleaned the classroom yesterday
为什么was后面用she(主格)?
这是个强调句,被强调部分在句子中作主语,所以用she.
She cleaned the classroom yesterday.
再问: 那如何判别它是一个强调句呢
再答: It is +强调部分 +that/who+其他部分。 强调部分是人用who, 否则用that
再问: 那被强调部分是短语还是句子还是什么?
再答: 出句子中的谓语部分外都可以。 It was the classroom that she cleaned yesterday. It was yesterday that she cleaned the classroom.
