情态动词should/oughtto/hadbetter
◆should和oughtto
1.should作为情态动词,没有人称和数的变化。
通常用来表示现在或将来的责任或义务,译作“应该”、“应当”,这时它可以和oughtto互换使用。
例如:
should/shouldn’t
I/You/He/She/We/They+discussit.
oughtto/oughtnotto
Youshould/oughttocompleteyourtestintime.
你们应该按时做完你们的实验。
一般疑问句及回答:
---Shouldwediscussitnow?
---Yes,weshould/oughtto.
---Oughtwetodiscussitnow?
---No,weshouldn’t/oughtnotto.
Eg:
Weoughttobemorecarefulwithourhomework.
Theyshouldfinishtheworkontime.
Heoughtnottodoitatonce.
2.oughtto/should区别
should谈的是自己的主观看法,
oughtto则更多反映客观情况,在谈到法律、义务和规定时使用。
Eg:
Weshould/oughttohelpeachotherandlearnfromeachotherinourwork.
Sheisyourmother,soyououghttosupporther.
WeoughttogoandseeMarytomorrow,butIdon’tthinkwewill.
◆hadbetter
为固定搭配,无人称,数和时态的变化,用来表示给予建议,后面接动词原形,hadbetter
dosth意为“最好干某事…”
Eg:
Youhadbetterbeontimeforyourlessons.你最好准时上课。
hadbetter通常缩写成’dbetter
Eg:
Youhadbetterbecarefulwhenyoucrossthestreet.=You’dbetterbecarefulwhenyou
crossthestreet.当你过马路的时候,你最好小心点
肯定形式:
hadbetterdosth最好干某事
否定形式:
hadbetternotdosth最好不要干某事
Eg:
Youhadbettergoandseeadoctor.你最好去看下医生。
Hehadbetternotgooutnow.他最好现在不要出去。
含有hadbetter的反义疑问句,把had作为助动词,否定用hadn’t。
Eg:
We’dbetterstayathometoday,hadn’twe?
我们最好是呆在家里,是吗?
Shehadbettergetreadyforthecomingexam,?
其他情态动词复习
◆can(could)与beableto
can=beableto能够,表示能力
区别:
can只有两种时态,即can和could
beableto有多种时态,如was/wereableto,willbeableto,have/hasbeenableto等
表示过去通过努力终于做成了某事要用beableto,而不能用can。
Eg:
Iwasabletoswimtothebankaftertheboatturnedover.
can能表否定猜测,beableto不能。
can的这种用法主要用于疑问句和否定句。
Eg:
Somebodyisknockingatthedoor.Whocanitbe?
Itcan’tbeourteacherwhoisknockingatthedoor.
其肯定形式是mustbe。
如:
Itmustbeourteacherwhoisknockingatthedoor.
◆haveto和must
'必须'haveto表示客观的必须,
must表示主观的必须
Mybrotherwasveryill,soIhadtocallthedoctorinthemiddleofthenight.我弟弟病得很厉
害,我只得半夜里把医生请来。
(客观上需要做这件事)
Hesaidthattheymustworkhard.他说他们必须努力工作。
(主观上要做这件事)
haveto有人称、数、时态的变化(hasto/hadto)
must只有一种形式。
Hehadtolookafterhissisteryesterday.
否定结构:
don'thaveto表示"不必"
mustn't表示"禁止",
Youdon'thavetotellhimaboutit.你不一定要把此事告诉他。
Youmustn'ttellhimaboutit.你一定不要把这件事告诉他
[注]:
回答must提出的问题
Eg:
---MustIdoitnow?
---Yes,youmust./No,youneedn't.
◆may和might
表示推测,意思是:
可能,可用于肯定与否定推测。
Itmayrainthisevening.You'dbettertakeanumbrella.今晚可能要下雨,你最好带上雨伞。
may过去式为might
◆need
做实义动词需要needtodosth否定形式:
don’tneedtodosth
做情态动词需要needdosth否定形式:
needn’tdosth
Eg:
Youneedfinish/needtofinishyourhomeworktoday.
[注]:
need/must提问,回答需要注意:
NeedIdomyhomeworknow?
--Yes,youmust(你必须)./No,youneedn’t/youdon'thaveto(你不必).
MustIfinishmyhomeworknow?
--Yes,youmust(你必须)./No,youneedn’t/youdon'thaveto(你不必).
