*用法：
1.使役动词make/let/have和感官动词see/lookat/notice/listen(to)/hear/help/
watch…等后面跟省去to的动词不定式，e.g.
Shehadmerecitethewholetextthis
morning.
Ilistenedtothebirdssinginthewood.
Theywerewatchingthebabyplayinthe
garden.

*注意：
1)在使役动词中,只有make能用在被动中。
I’mmadetodosomehouseworkat
weekend,washingdishes,forexample.
2)而且所有这些动词用在被动时不省略
“to”.e.g.
Theoldladywashelpedtowalkacross
thestreet.
Sheisoftenseentodosomeexercise
earlyinthemorning.
2.以下动词如wish,hope,manage,ask,offer,promise,pretend,decide,agree,
expect之后用不定式作宾语或跟复合宾语。
Theparentsareexpectingtheirsontocomebackhomeasearlyasquickly.
Theymanagedtogetsomewaterforthe
woundedsoldiers.
3、动词不定式的被动语态
如果不定式的逻辑主语是不定式的执行者，用主动语态；而如果不定式的逻辑主语是不定式动作的承受者，则用动词不定式的被动语态。
It’snecessaryforhertobeinvitedtothemeeting.
It’sagreathonorformetobeaskedtomakeaspeechhere.
Iwishtobegivenmoretime.
There’smuchtobedonetoprotectour
earthfrombeingfurtherpolluted.
4.动词不定式之后用主动代替被动语态：
1）系表结构之后，e.g.
Thequestioniseasytoanswer.
It’shardtotellthedifferencebetween
thetwo.
2)动词不定式和宾语有动宾关系，和主语又有主谓关系时，用主动代替被动,反之用被动。Ihavesome
