三基本用法
1.can的用法
1)表能力
can表能力时意味着凭体力或脑力或技术等可以无甚阻力地去做某事。
Icanclimbthispole.我能爬这根杆子。
Heisonlyfour,buthecanread.他只有4岁,但已认得字了。
Firecan’tdestroygold.火烧不毁金子。
2)表可能性
多用于否定与疑问结构中,但也可用在肯定句中。
Canthenewsbetrue?
这消息可能是真的吗?
Itcan’tbetrue.它不可能是真的。
Whatcanhepossiblymean?
他可能是什么意思?
3)表示允许(和may意思相近)常见于口语。
Can(May)Icomein?
我能进来吗?
CanIsmokehere?
我可以在这里抽烟吗?
2.could的用法
1)表过去的可能和许可,
FathersaidIcouldswimintheriver.爸爸说我可以在河里游泳。
2)表过去的能力
IcouldswimwhenIwasonlysix.我刚六岁就能游泳。
3)表“允许”。
可表示委婉客气的提出问题或陈述看法,不是can的过去时态。
---CouldIuseyourbike?
---Yes,youcan./No,youcan’t.
注意:
beableto表示能力,意为“能够做成某事”,相当于can的用法,但是有区别:
can泛指
一般的能力;
beableto则主要指成功做了某件事的能力。
3.may(might)的用法
1)表示请求、可以、允许。
Youmaydrivethetractor.你可以开那台拖拉机。
2)当回答由may引起的问题时,否定答语要用mustnot,表示“不许可”、“不应该”、“不行”。
MayIcomein?
Yes,youmay.No,youcan’t.No,youmaynot.No,youmustn’t
3)might是may的过去式,语气比may更加委婉;
4.must的主要用法
1)表示必须、必要
Wemustdoeverythingstepbystep.我们必须按部就班地做一切事情。
Whymustyoualwaysbotherme?
为什么你偏要打扰我呢。
2)mustbe+表语的结构,通常表示猜测,含有“一定”之意。
(只用在肯定句中)
Hemustbeanhonestboy.他一定是个诚实的男孩。
Thismustbeyourroom.这一定是你的房间。
3)must的否定式有两个:
当回答由must引起的问题时,否定答复要用needn’t或don’thaveto表示“必”、“无须”、“用
不着”、“不一定”的意义。
当表示“不应该”、“不许可”、“禁止”时,就用mustnot。
MustIgotomorrow?
明天我必须去吗?
Yes,youmust./No,youneedn’t.
must=haveto.但有区别:
must表示说话人的主观思想,haveto“不得不,必须”,表示客
观需要,客观条件只能如此。
Youmustdoitnow.你必需现在就干。
(说话人认为必须现在干)
Ihavetogonow.(客观条件必须现在走)
5.need的主要用法
1)need作情态动词,表“需要”,多用在否定式或疑问句中.
NeedIattendthemeetingtomorrow?
-Yes,youmust./No,youneedn’t.
-Youneednothandinthepaperthisweek.
2)need也作实义动词,用法是needtodosth./sth
Heneedstofinishhishomeworkintime.
Ineedyourhelp.
3)need主动表被动的用法:
sthneedsdoing=sthneedstobedone.
Theroomneedscleaning.=Theroomneedstobecleaned.
4)need做名词的用法:
meetone’sneeds=satisfyone’sdemandsin(great)needof(急需)
6.should的主要用法
意思为“应该”。
表示劝告、建议、命令,其同义词是oughtto;
在疑问句中,通常用should代替oughtto。
Youshouldgotoclassrightaway.
ShouldIopenthewindow?
7.ought“应当;
应该”。
用法则oughttodosth.
Yououghttoreadthesebooksifyouwanttoknowhowtorepairthemotorcar.
8.shall的用法
意思为“将要/应该”
1)用于第一人称征求对方的意见,如:
WhatshallIwearonthejourney?
我路上穿什么好呢?
Shallwedance?
我们跳舞好吗?
9.情态动词will和would的用法
will(would)表决心、愿望。
would为will的过去式,可用于各人称。
I'
lldomybesttocatchupwiththem.
llneverdoitagain,that'
sthelasttime.
Hesaidhewouldhelpme.
will,would用于第二人称疑问句表示说话人向对方提出请求或询问,用would比will更
婉转,客气。
10.maybe与maybe
二者都有“或许,也许”的意思,但用法不同:
(1).maybe是情态动词,只能用于句子中,
如:
It’seighto’clocknow.Myfathermaybeathome.
(2).maybe是副词,相当于perhaps,probably,likely,常用于句首。
It’seighto’clocknow.Maybemyfatherisathome.
11.hadbetter最好...
hadbetterdosth./hadbetternotdosth.(重点)
Youhadbetterkeepsilentinclass.
四、易错点:
(一)、can,may,must,need,should的提问与应答:
(1).CanIgotothecinematonight?
Yes,youcan./No,youcan’t.
(2).MayIhavealookatyourphotos?
Yes,youmay/can./No,youmustn’t/can’t.
(3).MustIbookaticketfortheconcertrightnow?
Yes,youmust./No,youneedn’t/don’thaveto.
(4).NeedIwatertheflowersinthegardenintheafternoon?
Yes,youneed/must./No,youmustn’t.
(二)、表示判断:
may/maynot,must(be)/can’t(be)
(1).判断语气坚定,有理有据(常摆出理由)
.肯定判断(must)
e.g.Thelightintheofficeison.Ourteachermustbestillworking.
Itmusthaverainedlastnight,forthegroundiswetandmuddy.
.否定判断(can’t/cannot)注:
不能用mustnot或mustn’t形式
e.g.Mr.Greencan’tbeathome,forImethimatthestreetjustnow.
Thisbookcan’tbeBetty’s.Shedoesn’tlikedetectivestories.
(2).判断语气不坚定,模棱两可,不确定,常附带有I’mnotsure/Idon’tknow等句子。
e.g.—HowsoonwillyourfathercomebackhomefromLondon?
—Maybeinaweek,butI’mquitenotsure.
