  动词不定式用法 词不定式(todo)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。
  例:To go in for sports helps you stay fit 1.(book4,L28)It helps you stay fit to go in for sports.It is dangerous to swim in the deep 2 sea on your own 3.
  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 4.(him为逻辑主语)
  2、表语:Our duty 5 is to protect 6 the enviroment.
  3、动词宾语:此种情况可按固定搭配或句式去记。
  例:would 7 you like to see my photos? Kevin planned 8 to visit his uncle.(book4,L11)
  和plan用法一样的词还有:start,want,agree,hope,begin,decide等。
  I found 9 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 10 song in the meeting 11 room.
  5、定语:动词不定式做定语放在所修饰的名词的后面。
   L1)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 12 in photos of their
  families for me to look at.(book4,L2)
  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 .
9、在初中阶段还涉及到“不定式被动语态一般式(tobe+过去分词)”
  例:There are twenty more trees to be planted.
