雅思语法：非谓语动词

　　非谓语动词

　　1.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。

　　2.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）

　　4）用法：

　　A. 作主语：To learn a foreign language is not easy . = It's not easy to learn a foreign language .

　　B. 作表语：The most important thing is to finish the work on time .

　　C. 作宾语：

　　a. 动词+to do . He decided to buy a new watch . （agree, choose, want, hope, like, wish, learn, love, plan, try, start, afford …）

　　b. 动词+疑问词+to do I don't know where to put the bike .

　　c. 动词+形式宾语（it）+宾补+to do I find it important to learn a second foreign language .

　　D. 作补语：

　　c. 表示原因：He is sorry to hear that . I am glad to see you .

　　5）动词不定式to 的省略：

　　A. 在感官动词feel, hear, see, watch, notice 及使役动词have, let, make等后面要省to，但在变被动语态时要还原不定式to。

　　I often saw him go out of the room .-------- He was often seen to go out of the room by me .

　　B.在had better, would rather, do nothing but等后面常省to。

　　6）动词不定式的否定形式：not + to do ，有时也可以用-never + to do 结构。

　　2）完成式：主动语态：having +动词过去分词，被动语态：having been +动词过去分词（表示动作或状态在谓语动词的动作或状态之前就发生）Children enjoy watching animated cartoon . I don't remember having ever seen the film .

　　3）动名词的否定形式：not + 动名词（v-ing） I regret not being able to help you .

　　4）用法：
