高中英語情態(tài)動詞講解與練習(xí)

高中英語情態(tài)動詞講解與練習(xí)高中英語情態(tài)動詞講解與練習(xí)高中英語情態(tài)動詞講解與練習(xí)V:1.0精細整理，僅供參考高中英語情態(tài)動詞講解與練習(xí)日期：20xx年X月高中英語語法之情態(tài)動詞（一）情態(tài)動詞的定義

：情態(tài)動詞表示說話人對某一動作或狀態(tài)的態(tài)度。

（二）情態(tài)動詞的特點

：1）有一定詞義；2）不受主語人稱和數(shù)的變化影響；3）與主要動詞的原形（或稱不帶to的不定式）一起構(gòu)成謂語（除ought

to作固定詞組看待）。

情態(tài)動詞無人稱和數(shù)的變化,情態(tài)動詞后面跟的動詞需用原形,否定式構(gòu)成是在情態(tài)動詞后面加"not"。個別情態(tài)動詞有現(xiàn)在式和過去式兩種形式,過去式用來表達更加客氣,委婉的語氣,時態(tài)性不強,可用于過去，現(xiàn)在或?qū)?。情態(tài)動詞屬非及物動詞，故沒有被動語態(tài)。Hecouldbeheresoon.他很快就來。Wecan'tcarrytheheavybox.我們搬不動那箱子。I'msorryIcan'thelpyou.對不起，我?guī)筒簧夏?。基本助動詞與情態(tài)助動詞最主要的區(qū)別之一是，基本助動詞本身沒有詞義，而情態(tài)助動詞則有自己的詞義，能表示說話人對有關(guān)動作或狀態(tài)的看法，或表示主觀設(shè)想：Whathaveyoubeendoingsince（構(gòu)成完成進行體，本身無詞義）IamafraidImustbegoing.（一定要）Youmayhavereadsomeaccountofthematter.（或許已經(jīng)）除此之外，情態(tài)助動詞還有如下詞法和句法特征：1）除ought和used以外，其他情態(tài)動詞后面只能接不帶to的不定式。如果我們把oughtto和usedto看做是固定詞組的話，那么，所有情態(tài)動詞無一例外地只能接不帶to的不定式：Weusedtogrowbeautifulroses.Iaskedifhewouldcomeandrepairmytelevisionset.2）情態(tài)助動詞在限定動詞詞組總是位居第一：Theyneednothavebeenpunishedsoseverely.3）情態(tài)助動詞用于第三人稱單數(shù)現(xiàn)在時的時候，沒有詞形變化，即其詞尾無-s形式：Shedarenotsaywhatshethinks.4）情態(tài)動詞沒有非限定形式，即沒有不定式和分詞形式，也沒有相應(yīng)的動名詞：Still,sheneedn'thaverunaway.5）情態(tài)助動詞的“時”的形式并不是時間區(qū)別的主要標(biāo)志。在不少場合，情態(tài)助動詞的現(xiàn)在時和過去時形式都可以表示現(xiàn)在、過去或?qū)頃r間：WouldyoumindverymuchifIaskyoutodosomethingShetoldhimheoughtnottohavedoneit.6）情態(tài)助動詞之間是相互排斥的，即在一個限定動詞詞組中只能出現(xiàn)一個情態(tài)助動詞，但有時卻可以與have和be基本助動詞連用：Youshouldhavewashedthewound.Well,youshouldn'tbereadinganovel.（三）情態(tài)動詞有四類：①只做情態(tài)動詞：must,can(could),may(might),oughtto②可做情態(tài)動詞又可做實義動詞：need,dare③可做情態(tài)動詞又可做助動詞：shall(should),will(would)④具有情態(tài)動詞特征：have(had,has)to,usedto⑤情態(tài)動詞表猜測（四）情態(tài)動詞的基本用法

need和dare既可用作情態(tài)動詞，也可用作實義動詞。用作情態(tài)動詞時，主要用于否定句和疑問句。用作實義動詞時，可用于各種句式。

1.用作情態(tài)動詞

day

（cI

say…為固定習(xí)語）

（二）情態(tài)動詞后跟完成式和進行式的用法

1.情態(tài)動詞后跟完成式，表“應(yīng)當(dāng)已經(jīng)……”，“想必已經(jīng)……”，“本來可以……”等意。
