Ⅱ.语法:
情态动词
一、情态动词的定义
情态动词是一类用于表示说话人的语气和情态的助动词。
常表示命令、请求、拒绝、义务、可能、需要等。
二、情态动词的特点
1.情态动词无人称和数的变化,
2.情态动词后面跟的动词需用原形,否定式构成是在情态动词后面加"
not"
。
3.个别情态动词有过去式,过去式用来表达更客气,委婉的语气,时态性不强,可用于过去,现在。
三、情态动词的用法
1.can/could;
can’t/couldn’t(否定)
1)表示能力,意为“能、会”,例如:
如:
IcanspeakalittleEnglish.--Canyourideabike?
Ican’tswim.--Yes,Ican./No,Ican’t.
2)表示请求或允许,多用于口语中,意为“可以、能”等
如:
Youcangohomenow.现在你可以回家了--CanIborrowyourbike?
Youcan’tstopyourcarhere.--Yes,youcan./No,youcan’t.
3)用于否定句、疑问句中,表示猜测、怀疑或不肯定.
Lucycan’tbeathomenow,shewenttotheparkjustnow.
Wherecanitbe?
Ican’tfindmyfootball.
【注意:
】
1)could是can的过去式,有两种用法,一种表示过去式;
一种用来表达更加客气,委婉的语气,时态性不强,可用于过去,现在。
2)beableto意为“有能力,能够做...”,相当于can/could,但它有人称,数和时态的变化。
2.may;
maynot(否定)
1)表示“请求,许可”,此时与can同义,可以互换使用
MayIborrowyourbike?
CanIborrowyourbike?
Yes,youmay./No,youmaynot.Yes,youcan./No,youcan’t.
2)may/might表示不太肯定的猜测,意为“有可能”
Lucymaycometoschoollatetoday.
Itmightraintoday.
【注意】:
might是may的过去式,有两种用法,一种表示过去式,一种表示更加委婉,客气的语气或对可能性的怀疑。
3.must;
mustn’t(否定)
1)must(“必须”,表示命令),mustn’t(“一定不能”,表示强烈禁止...)
Youmustgotobedbefore22:
00pm.
Youmustn’tplaywithfire.It’sdangerous!
--MustIwritedownthesentences?
--No,youneedn’t.(--No,youdon’thaveto)
注意:
在回答must的疑问句中,否定回答用needn’t或don’thaveto表示“不必”,不用mustn’t
2)must还可以表示非常肯定的猜测,意为“一定”
ThegirlinaredskirtmustbeLucy.
3)must/haveto的区别:
①.must表示必须,强调主观上的愿望;
haveto表示“不得不”,强调客观需要
Youmustgobebedbefore22:
00pm.Mybikeisbroken,soIhavetogotoschoolonfoot.
②.haveto有人称、数、时态的变化;
must则没有。
Ihavetocleantheclassroomtoday.Shehastofinishherhomeworkfirst.
Itwaslate,hehadtogotoschoolwithoutbreakfast.
