四、it 用作形式主语

替代作主语的从句、动词不定式、 动名词, 而把真正作主语的从句、 动词不定式、动名词置于句尾。

归纳 it作形式主语的句型常见的有:

It is clear ( obvious, true, possible, certain....) that It is said (reported,believed....) that ... It is suggested ( ordered /demanded/insisted/ commanded... ) that ...从句用虚拟语气 It is a pity ( shame/duty/fact/honor/no surprise... ) that It happens (seems, looks, appears ) that... It doesn’t matter( no wonder…)+wh-/how-clause It takes sb. ... to do sth… It is no good (use ) doing sth…

It looks ( seems ) as if ...

五、it作形式宾语 当复合宾语中的宾语是不定式、动名词宾语 从句时, 往往把宾语放在它的补足语后面, 而用it 作形式宾语, 放在宾语补足语之前。 该句型中的it 作形式宾语, 常用的动词有 think, believe, make, find, consider, feel等。

5.作形式宾语( Preparatory Subject )
为了记忆方便我们把该句型总结为"6123结构"。 6指主句中常用的动词:think,believe,make,find, consider,feel; 1指的是形式宾语it; 2指的是宾补的两种形式:形容词或名词; 3指的是真正宾语的三种形式:不定式短语,动名词短语 或从句。
