动词不定式作定语与被修饰词之间的三种关系

动词不定式具有形容词性质，所以，它在句子中可作名词或不定代词的定语。但是，这种定语往往只能后置，并且与被修饰的词之间有一定的逻辑关系。这些关系常见的有三种。
1、不定式与被修饰的名词或代词有逻辑上的动宾关系。
He told me he had a composition to write.
I want to get something to drink.
I have a lot of homework to do.
由上述例句得知，此时的不定式必须是及物动词。如果是不及物动词，其后就带一个结构或含义上所需要的介词。如：
Will you please bring me a chair to sit on?
She has nothing to worry about.
2、不定式与被修饰的名词或不定代词有逻辑上的主谓关系。如：
He was the last one to arrive.
Is there anyone to take care of the children.
例句中的不定式动作的逻辑主语分别是one和anyone。此时的不定式在意义上相当于一个定语从句。如：
Among the men to take part in the work(==Among the men who are totake part in the work),he is probably the most active.
3、不定式所修饰的词在意义上通常是用于不定式所做某种事情的。如：
We have got a new way to kill field mice.
I think he will have a chance to go to his hometown.
可以看出，way是用来to kill field mice, chance是用来 to go to hishometown。因此，这种类型的不定式译法较灵活。可译作“…的”或“来/去…”
