不定式做后定置语 - 柯帕斯英语网

曹老师，您好，我看了您的两个关于to do 做动词不定式的回复，

1.是说所有的to do做后置定语都能还原为定语从句么？

2.to do修饰的名词有什么限制么？

非常感谢！

1 是说所有的to do做后置定语都能还原为定语从句么？

通常不定式作定语都可以改写为一个定语从句。例如：

He was the first person to arrive. 主谓关系

= He was the first person who had arrived.

I have a lot of work to do. 动宾关系

= I have a lot of work that I must do.

This is a comfortable chair to sit in. 动（介）宾关系

= This is a comfortable chair that one can sit in.

Summer is the best season to swim. 动状关系

= Summer is the best season that one can swim. (that为关系副词，= in which)

I have to give up the plan to rebuild my house. 同位关系

= I have to give up the plan which is to rebuild my house.

但凡事不可绝对。并不是所有的不定式作定语都可以改为定语从句的。例如：

We shouldn't doubt his ability to sovle complecated problems.

这个不定式作定语很难改写为合适的定语从句。

2.to do修饰的名词有什么限制么？

没有特殊的限制。只要不违反逻辑，就可以用不定式作定语。
