动词不定式复习

语法复习：动词不定式

动词不定式（to do）是初中英语课的一个重点，也是中考要考查的一个项目。动词不定式属于非谓语动词的一种形式，很多同学经常把它和谓语动词混在一起，掌握起来有困难。下面我们对动词不定式的用法做简单归纳，帮助同学们记忆：

一、动词不定式在句子中不能充当谓语，没有人称和数的变化。

二、动词不定式是由“ to+动词原形”构成（有时可以不带to）。动词不定式的否定形式是“ not+动词不定式” （not不与助动词连用）。

三、动词不定式短语具有名词、形容词和副词等的功能，可在句中用做多种句子成分。

1主语：常置于句末，而用it代替其做形式主语。

To go in for sports helps you stay fit.

It is dan gerous to swim in the deep sea on your own.

注：此句式中不定式逻辑上的主语可由for或of引出，逻辑主语由of引出时，表语的

形容词为kind, nice, good, polite, clever, foolish, right, wrong 等表示评价的形容词。例：It ' s right of him to refuse the invitation. （him 为逻辑主语）

2、表语：Our duty is to protect the environment.

3、动词宾语：此种情况可按固定搭配或句式去记。

例: Would you like to see my photos?

Kevin pla nned to visit his un cle.

禾口pla n 用法一样的词还有：start, want, agree, hope, beg in, decide 等。

I found it very difficult to get a job. (it 为形式宾语)

4、宾语补足语：

(1) 在多数复合宾语及物动词后要带to。

例: I asked a friend to read it to me. (book4 ，L2)

(2) 在表示感觉、致使等意义的动词(see, watch, hear, feel, notice, observe, make, let, have, help 等)后不带to。

例: They heard him sing a pop song in the meeting room.

5、定语：动词不定式做定语放在所修饰的名词的后面。

例: I have something important to say.

6、形容词补足语：在表示心理、感情、评价等的形容词后，对其进行补充说明。例: We are very

glad to meet you again.

7、状语：表示目的、原因、程度等。

例：They brought in photos of their families for me to look at.

8、"疑问词+不定式”用法：不定式前可带what, who, which, where, when, how 等疑问词，这种不定式短语在句中多用做宾语。

例: He didn ' t tell me where to go.
