[动词不定式]不定式作补语,第2张

1) 有些有动词+宾语+不定式的结构。例如:

advise allow cause challenge command compel
drive 驱使 enable encourage forbid force impel
induce instruct invite like/love order permit
make let have want get warn
persuade request send tell train urge


  例如;

  Father will not allow us to play on the street.  父亲不让我们在街上玩耍。

  The officer ordered his men to fire. 长官命令士兵开火。

  注意:有些动词如make,have,get,want等可用不定式作做宾补,也可用分词作宾补。现在分词表达主动,也表达正在进行,过去分词表达被动。

  2) 有些有动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去。例如:

consider find believe think declare(声称) appoint
guess fancy(设想) guess judge imagine know


  例如:

  We believe him to be guilty. 我们相信他是有罪的。

  We know him to be a fool. 我们知道他是个笨蛋。(to be 不能省去)

  典型例题

  Charles Babbage is generally considered ___ the first computer.

  A. to invent B. inventing  C. to have invented  D. having invented

  答案:C. 一般没有consider+宾语+be以外不定式的结构,也没有consider+宾语+doing的结构,排除A、B、D.consider用动词be以外的不定式作宾补时,一般要求用不定式的完成式,故选C.

  3) 有些动词可以跟there +to be的结构。例如:

  believe   expect   intend   like   love   mean
  prefer   want   wish understand      


  例如:

  We didn't expect there to be so many people there. 我们没料到会有那么多人在那里。

  You wouldn‘t want there to be another war. 你不至于想让另外一场战争发生吧。
