英語中強調句型就是採用it is +強調部分+that……強調部分可以為主語,賓語,表語,狀語……比如：對you are my friend.強調主語就是:it is you that are my friend.
It is (was) 被強調部分+that (who) + 句子其他部分。
此結構強調的成分僅限於主語，賓語和狀語。強調句的連詞只有兩個，that和who。當強調的部分是人，且為句子的主語時，才用 "who"，其餘用that。
原句： My father did the experiment in the lab yesterdayevening.
強調主語： Itwas my father who did the experiment in the lab yesterday evening.
強調賓語： Itwas the experiment that my father did in the lab yesterday evening.
強調時間： Itwas yesterday evening that my father did the experiment in the lab. (注意不用when)
強調地點： Itwas in the lab that my father did the experiment yesterday evening.
如果想強調謂語,那麼一般用助動詞do或者他的對應時態進行強調.比如：your father asks you to do your homework.強調謂語ask.如下：your father does ask you to do your homework.
