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 dangerous 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 planned to visit his uncle.和plan 用法一样的词还有:start, want, agree, hope, begin, 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。
