2.情態(tài)動(dòng)詞的特征:有一定的詞義，但不能單獨(dú)作謂語(yǔ)，后面接動(dòng)詞原形;沒有

人稱和數(shù)的變化（haveto除外）；有些情態(tài)動(dòng)詞有過去式，

$[]：can—could,may—might,will—would,dare-dared,haveto—hadto等。

T:Nowlet'slearnsomerelevantknowledgeaboutthisGrammar.

*總結(jié)歸納:幾種常見情態(tài)動(dòng)詞的用法

Step3:

Activity3:Learningofmodalverbs

一、beableto

l.beableto后接動(dòng)詞原形，表示某人有做某事的能力，與can的用法相近。如:

IamabletospeakEnglish.我能講英語(yǔ)。

2.beableto與can的辨析：

①beableto有多種時(shí)態(tài)，如:was/wereableto,will/shallbeableto,have/has

beenableto等，而can只有兩種時(shí)態(tài),即can和couldo

②beableto強(qiáng)調(diào)通過努力而獲得的能力，而can則強(qiáng)調(diào)自身已具有的能力。

如：

ShecansingthesonginEnglish.

她能用英語(yǔ)唱這首歌。

HewillbeabletosingthissonginEnglishinafewhours,too.

幾小時(shí)之后，他也能用英語(yǔ)唱這首歌。

（3）beableto強(qiáng)調(diào)一種結(jié)果,而can只強(qiáng)調(diào)一種可能。如：

Luckily,hewasabletoescapefromthebigfireintheend.

幸運(yùn)的是,他終于逃出了大火。

Ifhehadgothereafewhoursearlier,!couldhavesavedhim.

要是他早幾小時(shí)來,我還能救他。

（4）beableto的否定形式是在be后面直接加not,即benotableto;beableto

可用在may/might之后。如：

Thekidisnotabletowrite.

這孩子不會(huì)寫字。

Butwemaynotbeabletodothisforeveryscenario.

但是我們不能每一種場(chǎng)景下都這么做。

即時(shí)訓(xùn)練:選詞填空（can/beableto）

①Hemightfixyourcar.

②WhenIwasyoung,!climbanytreeinthewoods.

③Intoday'sinformationage,thelossofdatacauseseriousproblems

foracompany.

（4）Fatherspentafewhourstalkingtohim.Atlasthedropthesilly

idea.

二、haveto

①haveto和must的意義相近,只是must側(cè)重表示說話人的主觀看法,而have

to則表示客觀需要，如：

Imuststudyhad我必須努力學(xué)習(xí)。

YouhavetohandinyourcompositionsbeforenextMonday.

你必須在下周一前上交你的作文。

（2）haveto的否定形式是don'thaveto,相當(dāng)于neednt如：

Theydon'thavetobuyacomputeratpresent.

他們目前沒有必要買電腦。

③haveto有人稱、數(shù)和時(shí)態(tài)的變化，如：

Theyhadtospeedup,fortheweatherturnedterrible.

他們必須加快速度，因?yàn)樘鞖庾冊(cè)懔恕?/p>

Hehastostayathomebecauseofillness.

因?yàn)樯?他不得不待在家里。

*must表示義務(wù)、必要性、命令等，意為"必須，應(yīng)該"，更強(qiáng)調(diào)主觀態(tài)度。

must用于一般疑問句時(shí)，其肯定答語(yǔ)應(yīng)用"Yes,youmust."。其否定答語(yǔ)應(yīng)用

“No,youneedn't."或"No,youdon'thaveto."。must的否定式為mustnot/mustn't,

表示禁止。

即時(shí)訓(xùn)練:完成句子

①IherebecauseIhavenoumbrellawithme.

我不得不在這兒等，因?yàn)槲覜]帶傘。

②Yousmokehere.

這兒禁止吸煙。

③Wehurry,forthere'splentyoftime.

我們不必著急，因?yàn)闀r(shí)間很充裕。

（4）Wehomeby11c/clock.

我們必須在11點(diǎn)以前到家。

三、hadbetter

hadbetter后跟動(dòng)詞原形，表示“最好”，其否定式在hadbetter后力口not。構(gòu)

成疑問句時(shí)，則通常將had（而不是hadbetter）置于主語(yǔ)之前。

即時(shí)訓(xùn)練:翻譯句子

①你最好別去打擾他。

②我們最好在天黑前到達(dá)那里。

③你最好在10點(diǎn)前完成你的家庭作業(yè)。

④醫(yī)生是不是去看看他比較好?

四、dare&need

l.dare既可作情態(tài)動(dòng)詞，又可作實(shí)義動(dòng)詞。作情態(tài)動(dòng)詞時(shí)，通常用于否定句、

疑問句和條件狀語(yǔ)從句中，一般不用在肯定句中。

即時(shí)訓(xùn)練1：完成句子

①Shegooutaloneatnight.

她晚上不敢獨(dú)自出門。

②Howshedothingslikethattome?

她怎么敢對(duì)我做那樣的事呢？

③HeaskedmeifIrideahorse.

他問我是否敢騎馬。

dare作實(shí)義動(dòng)詞時(shí)，有時(shí)態(tài)、人稱和數(shù)的變化。不同的是,作實(shí)義動(dòng)詞時(shí)，在肯

定句中dare后面通常接帶to的不定式;在否定句和疑問句中,dare后可接帶to或

不帶t。的不定式。

即時(shí)訓(xùn)練2:完成句子

①HespeakEnglishatanytime.

任何時(shí)候他都敢說英語(yǔ)。

②Iwonderhowhesaysuchthings.

我納悶他怎么竟敢說出這樣的話來。

③Heanswer.

他不敢回答。

④Howyougointothelabwithoutyourteacher'spermission?

未經(jīng)你老師允許,你怎么敢進(jìn)實(shí)驗(yàn)室？

2.need作情態(tài)動(dòng)詞時(shí)，后跟動(dòng)詞原形，表示“需要，有必要〃，無(wú)人稱和數(shù)的變化,

多用于否定句、疑問句或條件句中。

Ifyouaretimepoor,youneedrunforonlyhalfthetimetogetthesamebenefits

asothersports.

如果你時(shí)間不充裕,你只需要跑一半的時(shí)間就可以獲得和其他運(yùn)動(dòng)同樣的效

果。

need作為實(shí)義動(dòng)詞時(shí),通常用法是：
