考研英语中每个题型(除写作外)都包含大量的长难句，是影响阅读的关键因素，也是广大考生复习的重难点所在。但是，归根到底，长难句的主干部分还是五个基本句型主谓、主谓宾、主系表、主谓双宾和主谓宾语宾补，甚至可以统一概括为主谓宾。所以要理解长难句，首先得搞明白句子的主干成分。首当其冲就是主语。英语中的主语可以由名词(短语)、动名词短语、不定式短语充当。当然还可以用句子充当，但是这样会产生头重脚轻的状况，影响句子平衡。为了避免这种情况，引入It 作为形式主语，而把真正的主语置于句末。常见的形式主语句型如下：

It follows that...	因此；由此可见

(四)It is/was + 名词短语 + that主从
