它具有动词的性质，有形式的变化，也可以有自己的宾语和状语，从而构成动词不定式短语。
也具有名词、形容词或副词的某些特征，在句中可以做谓语之外的所有句子成分，包括主语、表语、宾语、宾语补足语、定语和状语。

We thought it better to start early.They considered it important to get his permission.②a.不定式可作个别介词的宾语如but，except。
It had no effect except to make him angry.I had no choice but to wait.They could do nothing but wait for the doctor to come.*在介词except, but之后，如果前面有动词的do某种形式，不定式一般不带to，反之则带to。
