例句: It’s probably best to write the introduction last, after you know precisely what you are introducing. (选自 2008年 Part B)
分析: 该句是复合句。句子主干是It’s probably best to write the introduction last,其中it作形式主语,真正的主语是不定式to write the introduction last,从句what you are introducing又作know的宾语。
译文: 在你已经很清楚自己到底要介绍什么之后,或许把引言段放到最后写会更好。
例句: We are fortunate that it is, because building new educational systems there and putting enough people through them to improve economic performance would require two or three generations. (选自2009年Text 3)
分析: 该句是复合句。主句部分是we are fortunate...,在it is后省略了上文提到的内容,because引导原因状语从句,building new educational systems there和putting enough people through them to improve economic performance两个并列动名词短语作从句的主语。
