(3)few和little表示"几乎没有",侧重否定。few后接可数名词,little后接不可数名词。例如:

【情态动词】又叫情态助动词。它们具有以下特点:

⑴它们必须与其他动词连用,即:情态动词+动词原形

表示说话人对所述动作的看法,如需要、可能、意愿或怀疑等。

⑵绝大多数情态动词没有人称和数的变化,即第三人称单数不加-s

(以be和have开头的情态动词短语除外)。

⑶在意义上,情态动词具有“多义性”。

例:can既可表示能力,又可表示可能、允许等意义。

【情态动词的基本用法】

1.can的基本用法:

⑴表示体力或智力上的能力,即“能够,会”,可与be able to转换。

例:HecanspeakEnglish.=HeisabletospeakEnglish.

—Canyouplaybasketball?

—No,I can’t.

如果表示将来具备的能力,要用will be able to。

例:IfIhaveagoodsleep,Iwillbeabletodotheproblem.

⑵表示许可,主要用于口语,书面语一般用may。

例:—Canwegohomenow,please?

—No,you can’t.

Youcanonlysmokeinthisroom.

You can’t keepthelibrarybooksformorethanamonth.

⑶表示“可能”,与may同义,但一般用在疑问句中。

例:Whatcanhepossiblywant?

在否定句中,否定形式can’t表示推测“不大可能”。

例:Anybodycanmakemistakes.

Thenews can’t betrue.

与第一、二人称连用时,还可以就可能的解决问题的方式或可能的行为提出建议。在这里,也可用could使语气婉转。

例:Can/CouldwemeetagainneGtweek?下周我们可以再见面吗?

—Whatshallwedo?我们怎么办呢?

—Wecan/couldtryaskingLucyforhelp.——我们可以请露茜帮忙试试看。

Youcan/couldhelpmewiththecooking.你可以帮我做饭。

2.may的基本用法:

⑴表示“许可”,用can比较口语化。

例:Youmay/cancomeifyouwish.如果你想来,你就来。

Youmaynotpickflowersinthispark.本公园内不许摘花。

(maynot表示按规定不许可,如果用must n’t则表示说话人不许可。)

我可以在这里抽烟吗?

—表示明确的禁止。)

⑵肯定句中表示推测,“可能”。

例:Itmayraintomorrow.明天可能会下雨。

Thenewsmaynotbetrue.这个消息可能不会是真的。

注意:如果

例:Canitbetrue?那会是真的吗?

Whocanhebe?他究竟是谁呢?

⑶【注意】/we……?

—Yes,you—No

3.must的基本用法:

⑴表示必须,强调说话人的主观意志。

例:Imustgonow,or I’ll belate.

Youmustbeherebyten o’clock.

【注意】:表示“必须“时,must的否定式为而不是mustn’t。

也就是:—Must I/wedoitnow?

—Yes,you

—No,you

例:—MustIgowiththem?

—No,you .

⑵表示推测,一般只用于肯定陈述句,表示非常肯定。

例:She didn’t lookatme.Shemustbeangry.她不朝我看,一定是生气了。

HeisgoodatEnglish.Hemustknowtheword.他英语好,准知道这个词。

YoumustbeMr.Jones.想必您就是琼斯先生吧。

4.haveto的基本用法:

haveto可视为情态动词,但它与其他情态动词在用法上稍有不同。其他情态动词没有人称和数的变化,而haveto却有人称和数的变化,要视主语的不同而变化。

例:I/You/We/They have to….

He/She/It has to….

You don’t have to….

Doesshe have to…?

,意思是“必须,不得不”。

和must不同之处:must强调主观需要

haveto强调客观需要。

例:Sorry,I have to leavenow.对不起,现在我得走了。

I’ve got to gotoameeting.我得去参加一个会议。

Willhe have to workdeepintothenight?他将不得不工作到深夜吗?

5.need的基本用法:

need的基本词义是“需要”,它既可作情态动词,又可作实义动词。

⑴need用作情态动词时,只用于否定句和疑问句。它只有一种形式,后接动词原形。

例:I don’t believeyouneedworry.我相信你没有必要焦急。

—Need wegososoon?我们需要这么早就去吗?

—Yes,we must./No,we needn’t.是的,必须。/不,不必。

SoI needn’t tellhim,needI?所以我不需要告诉他,对吧?

请比较以下两句话的不同意思:

You needn’t buy thecoat.你没有必要买那件外衣。(你还没买)

You needn’t have bought thecoat.你没有必要买这件外衣的。(而你却买了)

【注意】/we……?

—Yes,—No,you

⑵need用作实义动词时,有时态、人称和数的变化。

如果人作主语,一般后接带to的动词不定式。即

如果物作主语,一般后用

例如:Ineedtolookupthiswordinthedictionary.

Mywatchneeds mending/to be mended.我的手表需要修理了。

We don’t needtoworktoday.(=We needn’t worktoday.)

Doesheneedtogorightnow?(=Needhegorightnow?)

6.hadbetter的基本用法:

hadbette r常略作’d better。现代语法认为它是一个助动词,因为它后接不带to的动词不定式。

意思是“最好做某事;还是做某事比较好”。

例:You’d bettergetsomesleep.你最好睡一会儿。

You’d betternotdothatagain.你最好别再做那件事。

Whathadwebetterdonow?我们现在怎么做才好呢?

Hadn’t webettertellherthetruth?我们是否最好不告诉她真相?

7.could,should,would,might表示推测:

①.must多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”。

如:Youhaveworkedhardallday.Youmustbetired.你已辛苦工作一整天了,一定累了。

Thebookmustbehis.Hisnameisonthecover.这本书一定是他的,封面上写着他的名字。

【注意】must不表推测时,在肯定句中意思为“必须(强调内在的职责)”,在否定句中意思为“不许、禁止”,以它开头的疑问句否定回答常用needn’t或don’t(doesn’t)haveto。

如:Wemustobeythetrafficrules.我们必须遵守交通规则。

Cars mustn’t beparkedhere.此处严禁停车。

—Mustwehandinthepapersthisweek?我们必须本星期交论文吗?

—No,you needn’t.不,你们不必(本星期交)。

②.can/could多用于否定句、疑问句或感叹句中表示推测、怀疑,两者在时间上没有差别。用can时不

相信的程度更强一些

如:Themanunderthetree can’t beTom.He’s gonetoEngland.这个人不可能是Tom,他已经去英国了。

Canitbetruethathewasfooledbyafive-year-oldboy?他被一个五岁的孩子愚弄了,这能是真的吗?

CouldthisbeaneGcuse?这会不会是个借口?

Howcanyoubesocareless!你怎么这样粗心!

③.may/might多用来表示把握性不大的推测,意思为“也许、可能”,might比may的把握性更小一些。

(注意区分“不可能”与“可能不”在把握性大小上的差异。)

如:Mr.Wang may knowProfessor Li’s telephonenumber.王先生也许知道李教授的电话号码。

This might be thekeyTomhasbeenlookingfor.这可能就是汤姆一直在找的钥匙。

She may not betheretoday.今天她可能不在那儿。
