不定式的被动态有多种形式,小编为大家整理了完整的不定式被动态用法,其中包括逻辑主语的省略以及主动表被动的各种用法,不看不要后悔哦。

 

当不定式的逻辑主语是动作的承受着时,不定式要用被动态。

例如:

1. I am proud to be thus chosen.

2. I hope to be nominated.

3. It is impossible for lost time to be made up.

4. To fetch water before breakfast seemed to them a rule never to be broken.

由上述诸例可以看出,当不定式的逻辑主语就是主句的主语时,逻辑主语不需要表示出来。

当不定式的逻辑主语不是主句的主语时,这种逻辑主语就必须表示出来。

 

get-型被动态也可以不定式的形式出现,

例如:

It was nasty for Mary to be / to get hurt.

在有些场合,既可用不定式主动态,也可用不定式被动态,意义没有区别

例如:

The boxes are not strong enough to use / to be used as a platform.

It was good for Hayden’s mother to leave / to be left until tomorrow.

 

但有时在there + be结构中,用不定式主动态和不定式被动态含义不同,

例如:

There was nothing to see ( There was nothing for one to see ).

There was nothing to be seen ( The thing being looked for was not there).

 

在下列场合中,习惯上用不定式主动态,尽管不定式的逻辑主语是动作的承受者,

例如:

This house is to let.

You are not to blame for what happened.

 

哇,区区一个不定式的被动态就有这么多种用法,有没有大开眼界呢?赶快收藏起来吧~
