【情態(tài)動詞的用法要點】

一．can和could

完整教案設(shè)計,課前熱身,課后練習(xí)

特殊說明：

（1）could用來表示懇求時，語氣委婉，主要用于疑問句，不能用于確定句，答語應(yīng)用

can（即：could不能用于現(xiàn)在時態(tài)的簡略答語中）。如：——CouldIuseyourdictionary?

——Yes,youcan.(否定回答可用：No,I’mafraidnot.)(2)can和beableto辨析

can(could)和beableto都可以表示力量，意思上沒有區(qū)分。但can只有現(xiàn)在式和過去式，而beableto則有更多的形式。如：

I’vealwayswantedtoabletospeakfluentEnglish.

Thosebagslookreallyheavy,areyousureyou’llbeabletocarrythemonyourown?但是，表示在過去某時的某一場合經(jīng)過一番努力，最終做成了某事，通常不用could，而用was/wereableto來表示。這時，was/wereableto相當(dāng)于managedtodo或succeedindoing。如：

Aftertheaccidentitwasalongtimebeforeshewasabletowalkagain.

Thefirewasverybig,butmostpeoplewereabletoescapefromthebuilding.(3)慣用形式“cannottoo”表示“無論怎么也不（過分）”。如：Youcannotbetoocareful.你越當(dāng)心越好。慣用形式“cannotbut+不定式（不帶to）”表示“不得不，只好”。如：Icannotbutadmireherdetermination.我不得不敬佩你的決心。

二．may和might

三．must和haveto

四．shall和should

五．will和would

完整教案設(shè)計,課前熱身,課后練習(xí)

特殊說明：would與usedto辨析

would可用來表示過去反復(fù)消失的動作，但不能表示過去存在的狀態(tài)，所以我們不能說：“shewouldbeaquietgirl.”另外，would強調(diào)過去某種特定狀況下的活動，是完全過去的事情，同現(xiàn)在沒有聯(lián)系。而usedto則著眼于過去和現(xiàn)在的對比，隱含現(xiàn)在已不存在，動作或狀態(tài)都可表示。Would可以表示不規(guī)章的習(xí)慣，usedto則不行。如：

Heusedtobeanaughtyboyandcausetrouble.Iusedtogetupatsixinthemorning.

Sometimesshewouldtakeawalkintheneighboringwoods.

Inthosedays,wheneverIhaddifficulties,IwouldgotoMr.Chenforhelp.

六．need和dare

完整教案設(shè)計,課前熱身,課后練習(xí)

七．ought的用法：

說明：should與oughtto表示“應(yīng)當(dāng)”時的區(qū)分

should表示自己的主觀看法，而oughtto的語氣中，含有“按道理應(yīng)當(dāng)”之意。若要反映客觀狀況或涉及法律義務(wù)和規(guī)定，一般用oughtto。如：Youshouldhelpthemwiththeirwork.

Youarehisfather.Yououghttogethimtoreceivegoodeducation.

八．“情態(tài)動詞+havedone”用法

完整教案設(shè)計,課前熱身,課后練習(xí)

情態(tài)動詞+havedone

用法表示主觀上對過去已經(jīng)發(fā)生的行為進行推想，意為“想必，準是，一定做了某事”

例句1.Shemusthavegonethroughalot.2.HemusthavevisitedtheWhiteHouseduringhisstayintheUnitedStates.1.Youmayhavelearntthenews.2.Hemaynothaveheardhisnamecalled.3.SorryI’mlate.Imighthaveturnedoffthealarmclockandgonebacktosleepagain.

musthavedone

may/mighthavedone

表示對過去已發(fā)生行為的推想，意為“或許/或許已經(jīng)(沒有)“。一般用于確定句或否定句中，不用于疑問句。用might則表示語氣更加不愿定。

canhavedonecannothavedone

表示對過去發(fā)生的行為的懷疑和不1.Wherecanshehavegone?確定，通常用在否定句和疑問句中。2.Couldhehavedonesucha(can換成could時語氣委婉)foolishthing?

couldhavedone

3.Theboycan’thavefinishedreadingthebooksosoonbecauseitisdifficulteventoanadult.可用于確定句中，表示“可能已1.Hecouldhavekilledhimself經(jīng)”之意，此外，還可以表示drivingatadangerousspeed.過去能做而沒做的事，有一種對過2.Youcouldhavebeenmore去為付諸實施的事情的惋惜。considerate.3.Youcouldhavedonebetter,butyouweretoocareless.表示“原來可能,但實際上沒有發(fā)生的事情”。另外，還可以表示“原來應(yīng)當(dāng)或可以做某事”之意，含有稍微的責(zé)怪語氣。

mighthavedone

1.Youshouldnotswiminthatsea.Youmighthavebeeneatenbyashark.2.Hemighthavegivenhimmorehelp,thoughthewasbusy.should/oughttohave用于確定句時，表示本該做某事，1.Heshouldhaveknownthat而實際上未做；用于否定句時，則donethepolicewouldneverallow表示不該做的事反而做了。thissortofthing.2.Youshouldn’thavedoneitsocarelessly.3.Yououghttohavereturnedthebookearlier.4.Yououghtnottohaverefusedhisoffer.needn’thavedone表示做了原來不必去做的事。留意：1.Youneedn’thavewateredthedidn’tneedtodo表示“沒必要做而plants,foritisgoingtorain.實際上也沒有做某事”2.Ididn’tneedtobuythe
