四个易混淆的结构 “It’s...that...”,“ It is ... since ...”,“ It is ... before...”和“ It is ... when ...”是四个形似的句子结构,填对连词不容易。 1.“It’s...that...” ①当it 为形式主语时,that等为主语从句的连词,例如: It is quite clear that he has read the book. 很显然, 他读过这本书。 It’s a problem where we could get so much money. 我们到哪里去弄这么多钱, 这是一个难题。 ②It is(was)+被强调的部分+that(who)+原句其它部分”来强调说话人的意愿: 例句:It was on Monday night that all this happened.所有这一切发生在周一晚上. It's me that he blamed.他怪的是我.
