Eg:
IcanspeakfluentEnglishnow,butIcouldn'
tlastyear.
注:
can和beableto辨析:
can只有现在式和过去式,而beableto有更多的形式。
I’vealwayswantedtoabletospeakfluentEnglish.
Thosebagslookreallyheavy,areyousureyou’llbeabletocarrythemonyourown?
was/wereableto表示“经过一番努力后做成某事”相当于managedtodo或succeedindoing
Aftertheaccidentitwasalongtimebeforeshewasabletowalkagain.
2、表“允许,请求”口语中常用could代替can,使语气更委婉
Couldyoulendmeyourequipment?
(班级中的清新女神的口气)
Canyoulendmeyourequipment?
(班级中的女汉子的口气)
could用来表示请求时,语气委婉,主要用于疑问句,不能用于肯定句,答语应用can(外国人比较直爽,拒绝就是拒绝,不用委婉的could。
—CouldIuseyourdictionary?
—Yes,youcan.(否定回答可用:
No,I’mafraidnot.)
3、表“猜测”(主要用于否定和疑问)肯定猜测用must
Itcan’tbeeasycaringforamanandachildwhoarenotyourown.
Canthemanovertherebeourheadmaster?
4、表“惊讶”译为“怎么能”(主要用于否定句,疑问句或感叹句)
Howcanyoubesocrazy?
5、(肯)表示客观可能性,常用来说明人或事物的特征,可翻译为“有时会”。
要表达具体某事实际发生的可能性时,不用can,需用could,may,might。
Asahumanbeing,anyonecanmakeamistake.
I’mconfidentthatasolutioncanbefound.
Hecanbeveryforgetfulsometimes.
Imaystayathomethisweekend.(实际可能性)
Petermightcometojoinus.(实际可能性)
惯用形式“cannot…too…”表示“无论怎么……也不(过分)”
Youcannotbetoocareful.你越小心越好。
惯用形式“cannotbut+不定式(不带to)”表示“不得不,只好”。
Icannotbutadmireherdetermination.我不得不钦佩你的决心。
【考点二】mayVSmight
1、表示允许,请求(May比较正式、客气,往往用于陌生人之间或正式场合,一般用于第一人称,might更委婉)
——MayIsmokehere?
——No,youmustn’t(或No,you’dbetternot.)
注意:
回答语比较直接。
否定回答一般用mustnot/mustn’t,表示“禁止、之意,但也可以用hadbetternot(最好别)或maynot(不可以),语气较为委婉。
2、表推测(也许,可能,大概)might更委婉
Itmayrainthisafternoon.
3、用于祈使句“祝”
Mayyoubehappy!
Longmayhelive!
愿他能持续住下去。
Mayyouhavemanymoredaysashappyasthisone.
Maysherestinpeace.愿她安息。
注:
与hope,wish的区别
Wishsb.sth.固定搭配所以wish后必须接n.
Hope(vi)+for
(vt)that/todo
惯用句式maywelldo(很可能)=belikelytodo
may/mightaswelldo(最好)=hadbetter
Youmayaswelltellusnow,we’llfindoutsoonerorlater.
Hemaywellnotforgiveyou.
【考点三】mustVShaveto
1、must主观“一定”haveto客观“不得不”
Imuststudyhard.(自己下定决心要努力学习)
Ihavetostudyhard.(被家长骂了之后不得不努力学习)
2、mustn’t表“禁止”
Eg:
Youmustn’teatintheclassroom.
1)否定形式:
Youmustn’tgothere.你不许去那里
Youdon’thavetogothere.你没必要去那里
2)疑问形式:
非得、、、、
---MustIcomebackinadvance?
---Yes,youmust./No,youneedn’t./youdon’thaveto.
3、must表肯定猜测
Youmustbeconfusedbyyourhandwriting.
must猜测的可能性很大,may/might可能性很小。
【考点四】shallVSshould
1、shall用于第一,三人称表示“征求意见”要区别于will表征求常用于第二人称willyou,may常用与第一人称mayI(比较正式,多用于陌生人)。
ShallIremovemycoat?
2、shall用于二,三人称中表示允诺,威胁,命令,警告
1.Don’tworry,youshallbeemployed.(允诺)
2.Heshallberegretfulforitoneday,Itellyou.(警告)
3.YoushalldoasIsay.(命令)
4.Ifyourchildrendon’tfinishyourhomework,youshallbepunished.(威胁)
3、shall必须(用在条约、规章、法令文件中表义务或规定,一般用于第三人称)
Intrudersshallbefined.非法闯入者将遭罚款。
4、should表应该1).推测
2).责任
Itshouldbeanicedaytomorrow.(推测)
Youshouldberesponsibleforyourbaby.(责任)
oughtto表示应该是客观的should表主观的
Youshouldhelpthemmakeprogress.
Youarehisfather.Yououghttogethimtoreceivegoodeducation.
3)should表“万一”(用在if引导的条件句中,一般情况不会发生,但也有发生的可能,从句谓语用should+动词原形构成,主句都一定用虚拟语气)
ShouldIbefreetomorrow,I’llcome.(万一我明天有时间,我就过来)
4)should表惊讶译为“竟然”与why,who,how,what连用
WhyshouldanyonewanttomarryTony?
【考点五】willVSwould
1、will表“意愿”,“请求”,“习惯”“功能译为:
能/行”
Heisthemanwhowillconductother.(意愿)这个是常考点
NomatterwhatIsaid,hewouldn’tlistentome.(表意愿的否定)
Willyoupleasetakeamessageforhim?
(请求)
Whenweworkedinthesameoffice,wewouldoftenhavecoffeetogether.(习惯)
Thedoorwilllock.(功能)
wouldVSusedtodo
would可用来表示过去反复出现的动作,不能表示过去存在的状态,另外,would是完全过去的事情,同现在没有联系。
而usedtodo表示过去常常,今非昔比
Inthosedays,wheneverIhaddifficulties,IwouldturntoMr.Chenforhelp.
Heusedtobeanaughtyboyandcausetrouble.
【考点六】dareVSneed既可以用作情态动词又可以用作实意动词
情态动词:
只用于否定与疑问前没有do后没有to/doing

和didn'
tneed,肯定式用needs/needed/need,

t)
