啥是动词不定式 语法解析：动词不定式的被动态

语法解析：动词不定式的被动态  

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~
