E.g. It was after the war was over that Einstein was able to come back to his research work again.
E.g. It was in front of the bank that the old lady was robbed.
E.g. It was because of the heavy rain that he came late.
3.如果被強調的成分有同位語,同位語也應提前。
It was from him,his chemistry teacher,that Paul learned to watch carefully in class.
4.被強調成分是作主語的代詞,用主格,是作賓語的代詞,用賓格
It was he that helped me yesterday. It was me that he helped yesterday.
5.被強調部分既包括人又包括物,用that不用who
It were the things and people that they remembered that they were talking about.
三、區分定語從句和強調句型某些定語從句和強調句型形式差不多,容易混淆。
如果去掉it is/ was 。..that句子仍然通順成立,則為強調句型,不成立不通順,則為定語從句。
E.g. It was three years ago that he went to American for a further study· 去掉It was that句子為Three years ago he went to America for a further study.句子通順,意思完整,那么,這就是一個強調句型。
