2.情態(tài)動詞除ought和have外，后面只能接不帶to的不定式。

3.情態(tài)動詞沒有人稱、數(shù)的變化，即情態(tài)動詞第三人稱單數(shù)不加-s。4.情態(tài)動詞沒有非謂語形式，即沒有不定式、分詞等形式。

情態(tài)動詞定義表示可能、懷疑、允諾、愿望、義務(wù)、必要、猜測等的動詞就是情態(tài)動詞。語法重點：情態(tài)動詞表推測英語中表示推測的情態(tài)動詞主要有must，can，could，may，might等,它們可以對過去、現(xiàn)在或?qū)淼那闆r作出語氣強弱不同的推測。

確定的推測含義不確定的推測(可能性依次減弱)含義肯定句must一定;必定can＞could＞may＞might可能否定句can’t＞couldn’t不可能maynot＞mightnot不大可能can和could也可以用于疑問句中表示推測。

情態(tài)動詞表示推測有以下幾種結(jié)構(gòu)表示:

情態(tài)動詞+do/be(表示對現(xiàn)在或?qū)淼膭幼骰驙顟B(tài)推測)eg:—Doyouknowwheresheisnow?—IthinkshemighttravelinBeijing.bedoing(表示對正在發(fā)生的事情推測)eg:Atthismoment,myfathercan’tbeworkingathome.情態(tài)動詞+havedone(表示對過去發(fā)生的事情推測)eg:Theroadiswet.Itmusthaverainedlastnight.havebeendoing(表示對過去正在進行的事情推測)eg:Yourmothermusthavebeenlookingforyouatthatmoment.must具體用法

must表示必須要做的事，意為“必須，應(yīng)該”。must一般問句的否定回答用needn’t或don’thaveto,而不用mustn’t,

mustn’t意為“不可以，不能”,表示禁止，不許可。另外，must還可表示有把握的推測，意為“一定、肯定”。must的過去式還是must。在回答以must開頭的一般疑問句時，否定式需用neednot(needn’t)，表示“不必”的意思。eg：—Mustwehandinourexercisestoday?—Yes,youmust.(No,youneedn’t)must意為“一定；準(zhǔn)是”。表示說話人對事物的推測可能性的程度非常大。①“mustbe+表語”意為“一定……”，表示對現(xiàn)在情況的推測。eg:Ican’tunderstandthem.Theymustbeforeigners.②“mustbe+現(xiàn)在分詞”意為“一定正在……”，表示對說話瞬間情況的推測。eg:ShemustbecookingnowbecauseIcansmellsomethingdelicious.③“musthave+過去分詞”意為“一定已經(jīng)……”,表示對過去情況的推測。eg:

Ican’tfindmykeys.Imusthaveleftthemathome.maymay表示允許、也許，意為“也許；可能；可以”，語氣不太可能。maynot，意為“也許不”。對may的一般問句的回答：肯定回答一般是：Yes,please./Certainly./Sure等否定回答一般是：Pleasedon’t./No,youcan’t/mustn’t.might是may的過去式，與may用法類似，語氣比may弱，表示推測的可能性更小，常用于肯定句和否定句中，不用于疑問句中。常見句型為：“maybe+表語”意為“有可能……”，表示對現(xiàn)在的可能推測。eg:Hemaybeangrybecausehelooksunhappy.can

can可表示能力、允許、可能性、懷疑猜測，意為“可以，會，能”；can’t意為“不會，不能，不可以”，還有“不可能”之意。could為can的過去式，用法與can類似，常用于過去時態(tài)中；could還可用于現(xiàn)在時態(tài)中表示委婉客氣，相當(dāng)于can；could也可表示驚訝?wèi)岩?，不相信。can’t和couldn’t一般用于否定句和疑問句中。eg：Hecouldn’tbeathief.

can表示推測時，常用于否定句、疑問句中，can’t意為“不可能；應(yīng)該不是”。常用句型為:''can/can’tbe+表語''意為''（不）可能……''，表示對現(xiàn)在情況的推測。

eg:Thatcan’tbeMaria,becauseshe’sinhospital.

There’ssomeoneoutside.Whocanitbe?could/might:如果表示推測的把握性不是很大時，用could或might。它們常用于肯定句或疑問句中，意為''也許;可能''。
