to do定语、状语 - 柯帕斯英语网

We're too busy to spare anyone to help you right now.
We force them to take measures.

Trust is expensive to restore.

1、请问老师，to help you是不是理解为定语、状语都可以呢？

2、to take measures为什么不能立即为状语呢？
3、请问to restore是做什么成分呢？

We're too busy to spare anyone to help you right now. 不定式to help you是to spare的宾语补足语。

We force them to take measures. to take measures 为force的宾语补足语。

不定式作状语，句子的主语为不定式的逻辑主语。不定式作宾补，宾语是不定式的逻辑主语。

Trust is expensive to restore. to restore为反射不定式，作表语形容词expensive的补足语。
