动词不定式动词不定式由“to+动词原形”构成，可以在句中作主语、宾语、表语、定语、状语、补足语等,但不能作谓语。不定式可以有自己的逻辑主语,即forsb.todosth.。想一想!1.不定式作主语

Tofinishthisreporttookhimaweek.Myjobistohelpthepoorperson.2.不定式作表语

Toseeistobelieve.WhatIwouldsuggestistoputoffthemeeting.3.不定式作宾语

Idecidedtoaskformymoneyback.

4.不定式作宾补1)带to的不定式作宾补。很多动词如:allow,

order,

force,

permit,

tell,

want,

wish,

forbid,

advise,

persuade,

warn等后面作宾补的不定式都带to。如:Hedidn’tallowustosmokeinhishouse. 他不允许我们在他的家里吸烟。2)不带to的不定式作宾补。使役动词make,have,let;感官动词see,watch,observe,hear,listento,notice等后面作宾补的不定式不带to。如:Hemadeafaceandmade everybodylaugh.他做了一个鬼脸,逗得大家都笑了。

如果上述结构变为被动语态,不定式就由原来的宾语补足语变为主语补足语,此时第2类动词(let,have无被动语态)后原来不带to的不定式要加to。如:Hewasseentogoupstairs.

有人看见他上楼去了。Becareful!注意:5.不定式作定语

Doyouhaveanythingtosayonthequestion?注意:作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是不定式的地点、工具等,不定式后面须有相应的介词。Heislookingforaroomtolivein.Thereisnothingtoworryabout.6.不定式作状语

动词后面跟V-ing还是不定式,含义不相同,总的来说,表示习惯的,一般性的动作多跟V-ing,一次性的具体的被动动作多跟不定式。1)Iliketogowithyou. 我想和你一块儿去。重点!Ilikereading.我喜欢阅读。Hepromisedtohelpher.他答应过要帮助她。WelovewatchingVCD.我们喜欢看VCD。2)remember,forget,regret后面跟V-ing时,表示过去的动作,后面跟不定式时,不定式表示将来的动作。

Iremembermeetinghiminthestreet.我记得在街上见过他。

Iremembertowritealettertomyparents.我想起来要给我父母亲写信。3)“stop+V-ing”表示停止做某事,“stop+不定式”表示停下来做某事。

Stopsmoking,please.

请不要抽烟。

Let'sstoptohavearest.

咱们停下来休息一下吧。4)meantodo打算做某事

meandoing意味着……Imeanttocatchupwiththeearlybus.Thismeanswastingalotofmoney.5)trytodo设法尽力做某事

trydoing试着做某事
