The earth will be a terrible place ______if we don't take care of it.

A; to live B to live in C to live on

动词不定式做定语 一般要和它所限定修饰的词构成逻辑上的动宾关系，所以我选择 B 但是答案选A 该怎么解释？？我在教科书上看到有句子确实是用A。 我想知道我的B 为什么不可以？？ 谢谢

不定式所修饰的名词如果是time, place或way，不定式后面的介词习惯上省去。

如：He had nono place to live.

This is the best way to work out this problem

区分:

We couldn't find a place to live that night.

We couldn't find a hotel to live in that night.
