情態(tài)動(dòng)詞（Modals）本身具有一定的詞義，不能獨(dú)立作謂語(yǔ)，必須和動(dòng)詞原形一起構(gòu)成謂語(yǔ)。情態(tài)動(dòng)詞雖然數(shù)量不多，但用途廣泛。常用的情態(tài)動(dòng)詞包括can(could),may(might),will(would),shall(should),must,need,dare,hadbetter,oughtto,usedto等。beableto后接動(dòng)詞原形，表示某人做某事的能力，可用于大多數(shù)時(shí)態(tài)。用于過(guò)去時(shí)態(tài)時(shí)，還可以表示“某人過(guò)去或當(dāng)時(shí)成功地做了某事”。例如：IwillbeabletospeakJapaneseinanotherfewmonths.

再過(guò)幾個(gè)月，我就能講日語(yǔ)了。Theywereabletoescapefromthebuildingwhenthefirebrokeout.

火災(zāi)發(fā)生時(shí)，他們?cè)O(shè)法從那棟建筑里逃了出去。1.beabletobeableto表示“能力”時(shí)，和can的用法相似。但也有區(qū)別：beableto有多種時(shí)態(tài)，如:was/wereableto,will/shallbeableto,have/hasbeenableto等,而can只有兩種時(shí)態(tài)，即can和could。beableto強(qiáng)調(diào)通過(guò)努力而獲得的能力，而can則強(qiáng)調(diào)自身已具有的能力。如：

She

can

singthesonginEnglish.她能用英語(yǔ)唱這首歌。Hewill

beableto

singthissonginEnglishinafewminutes,too.幾小時(shí)之后，他也能用英語(yǔ)唱這首歌。【beableto與can的辨析】beableto強(qiáng)調(diào)一種結(jié)果，而can只強(qiáng)調(diào)一種可能。如:

Luckily,hewasableto

escapefromthebigfireintheend.幸運(yùn)的是，他終于逃出了大火。Ifhegothereafewhoursearlier,I

could

savehim.要是他早幾小時(shí)來(lái)，我還能救他。beableto的否定形式是在be后面直接加not，即benotableto，如：

Thekidisnotableto

write.

這孩子不會(huì)寫字。But

we

may

not

be

able

to

do

thisfor

every

scenario.但是我們不能每一種場(chǎng)景下都這么做。dare作情態(tài)動(dòng)詞時(shí)，主要用于否定句、疑問(wèn)句和條件從句中，一般不用在肯定句中。

如：How

dare

yousayI'munfair?你怎么敢說(shuō)我不公平？情態(tài)動(dòng)詞dare可以有過(guò)去式dared，但也可以直接用dare表示過(guò)去式，或后接動(dòng)詞完成式，如：

Mother

dare(d)

nottellfathershe'dgivenawayhisoldjacket.母親不敢告訴父親她把他的舊上衣送人了。2.dare

＆

needneed作為行為動(dòng)詞，可用于肯定句、否定句和疑問(wèn)句中，其后可接名詞、代詞、動(dòng)名詞或帶to的動(dòng)詞不定式為其賓語(yǔ)。如：Youneedtopractice

readingaloudeveryday.注意對(duì)need問(wèn)句的回答:—NeedIfinishtheworktoday?—Yes,youmust./No,youneedn't./No,youdon'thaveto.needn’t對(duì)其它情態(tài)動(dòng)詞的回答:—ShallItellJohnaboutit?—No,youneedn't/don'thaveto.—Mustwedoitnow?—No,youneedn't/don'thaveto.3.havetohadbetter后接動(dòng)詞原形，意為“最好”，用于現(xiàn)在時(shí)和將來(lái)時(shí)，可用于一切人稱，沒(méi)有任何詞形變化。hadbetter的否定式是在其后加not，疑問(wèn)式是把had和not提前，例如：a.You'dbetter

sithereandhavearest.你最好坐在這兒休息一下。b.Shehadbetternottellliesanymore.她最好再也別撒謊了。c.Hadn’t

thedoctor

betterseehim?醫(yī)生是不是去看看他比較好？
