摘要： 不定式作补语 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 appoint guess fancy 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. 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.
