非谓语动词中的易错点

非谓语与其逻辑主语(即动作的执行者或承受者)之间有三种关系,如为主谓关系,则用现在分词或不定式的主动式;如为被动关系则用过去分词、现在分词的被动(强调动作正在进行)或不定式的被动式(动作将进行);如既无主动也无被动关系则只能用状语从句或独立主格结构(即非谓语加上自己的逻辑主语)

Judging/considering/genrally speaking/supposing 指说话者的动作,故只用主动式。如:

Having been ill in bed for nearly a month , he had a hard time passing the exam.

解析:从这个句子可以看出,句词的逻辑主语与句子的主语he一致,并且是主谓关系,所以用了现在的分词作状语,同时,分词的动作明显地发生在句子的谓语动词动作之前,故采用了现代分词的完成式。

In order to improve English , ________.

A. Jenny's father bought her a lot of tapes.

B. Jenny's father bought a lot of tapes for herself.

C. A lot of tapes were bought by Jenny.

D. A lot of tapes were bought by Jenny father.

解析:根据不定式短语我们可以推知,句子的逻辑主语应该是人而不是物,所以,应该排除CD,再就是应该是Jenny提高自己的英语,而不是她爸爸,故答案先B.

________,we decided to go out for a walk.

A. It is fine B. It fine

C. Being fine D.It being fine

解析:主句主语we与动词短语be fine之间既无主动关系与无被动关系,所以要加上自己的逻辑主语It,由于不存在主、被动关系,故不能选C项,而应该选D 项。

________more attention, the trees could have grown better. A. Given B.To give C.Giving D. Having giving

解析:give与主句的主语之间是被动关系,故选A.如为主动关系则选C.
