不定式做定语与不定式做补语的区别!

不定式作定语 不定式做定语通常要放在被修饰的词后,往往表示未发生的动作。例如：I have a lot of work to do。我有许多事要做。There was nothing to bring home that morning。那天早上（他回家时）两手空空。不定式作补语 1） 有些有动词+宾语+不定式的结构。例如：adviseallowcausechallengecommandcompeldrive 驱使enableencourageforbidforceimpelinduceinstructinvitelike/loveorderpermitmakelethavewantgetwarnpersuaderequestsendtelltrainurge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：considerfindbelievethinkdeclare（声称）appointguessfancy（设想）guessjudgeimagineknow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）3) 有些动词可以跟there +to be的结构。例如：believeexpectintendlikelovemeanpreferwantwishunderstand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。
