2022年中考英语考点：动词不定式

　　中考网整理了关于2022年中考英语考点：动词不定式，希望对同学们有所帮助，仅供参考。

　　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：

　　a. 动词+宾语+to do Tom asked me to show him the new shoes . (tell, wish, ask, want, like, beg, invite, allow, encourage…)

　　b. 动词+宾语+不带to的动词 He often saw Tom play football .(see, hear, feel, watch, notice, have, make, let…)

　　E. 作状语：

　　a. 表示目的：He went to Guangzhou to see his sons . He got up early in order to catch the first bus .

　　b. 表示结果：He is too tired to walk any farther . They aren't old enough to go to school .

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

　　F.作定语： I have something to tell you . I want to buy something to eat .

　　○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。
