非谓语动词
定义：动词除在句子中作谓语以外，还具有名词、形容词及副词的性质，在句中可作主语、表语、宾语、定语、状语和补语等，这就是动词的非谓语动词。可分为三种：动词不定式、分词和动名词。
动词不定式：
to + 动词原形(在某些情况下可以不带to )。(没有人称和数的变化，可以有自己的宾语和状语，可以有时态和语态的变化)
○1 一般式：主动语态：to do , 被动语态：to be + 动词过去分词(表示动作或状态与谓语动词的动作或状态同时发生或之后发生)
○2 进行式：主动语态：to be doing , 被动语态：无(表示动作或状态与谓语动词的动作或状态同时发生)
○3 完成式：主动语态：to have +动词过去分词，被动语态：to have been +动词过去分词 (表示动作或状态在谓语动作之前就发生)
