2.情态动词除ought和have外，后面只能接不带to的不定式。

3.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。4.情态动词没有非谓语形式，即没有不定式、分词等形式。

情态动词定义表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词就是情态动词。语法重点：情态动词表推测英语中表示推测的情态动词主要有must，can，could，may，might等,它们可以对过去、现在或将来的情况作出语气强弱不同的推测。

确定的推测含义不确定的推测(可能性依次减弱)含义肯定句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也可以用于疑问句中表示推测。

情态动词表示推测有以下几种结构表示:

情态动词+do/be(表示对现在或将来的动作或状态推测)eg:—Doyouknowwheresheisnow?—IthinkshemighttravelinBeijing.bedoing(表示对正在发生的事情推测)eg:Atthismoment,myfathercan’tbeworkingathome.情态动词+havedone(表示对过去发生的事情推测)eg:Theroadiswet.Itmusthaverainedlastnight.havebeendoing(表示对过去正在进行的事情推测)eg:Yourmothermusthavebeenlookingforyouatthatmoment.must具体用法

must表示必须要做的事，意为“必须，应该”。must一般问句的否定回答用needn’t或don’thaveto,而不用mustn’t,

mustn’t意为“不可以，不能”,表示禁止，不许可。另外，must还可表示有把握的推测，意为“一定、肯定”。must的过去式还是must。在回答以must开头的一般疑问句时，否定式需用neednot(needn’t)，表示“不必”的意思。eg：—Mustwehandinourexercisestoday?—Yes,youmust.(No,youneedn’t)must意为“一定；准是”。表示说话人对事物的推测可能性的程度非常大。①“mustbe+表语”意为“一定……”，表示对现在情况的推测。eg:Ican’tunderstandthem.Theymustbeforeigners.②“mustbe+现在分词”意为“一定正在……”，表示对说话瞬间情况的推测。eg:ShemustbecookingnowbecauseIcansmellsomethingdelicious.③“musthave+过去分词”意为“一定已经……”,表示对过去情况的推测。eg:

Ican’tfindmykeys.Imusthaveleftthemathome.maymay表示允许、也许，意为“也许；可能；可以”，语气不太可能。maynot，意为“也许不”。对may的一般问句的回答：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的过去式，与may用法类似，语气比may弱，表示推测的可能性更小，常用于肯定句和否定句中，不用于疑问句中。常见句型为：“maybe+表语”意为“有可能……”，表示对现在的可能推测。eg:Hemaybeangrybecausehelooksunhappy.can

can可表示能力、允许、可能性、怀疑猜测，意为“可以，会，能”；can’t意为“不会，不能，不可以”，还有“不可能”之意。could为can的过去式，用法与can类似，常用于过去时态中；could还可用于现在时态中表示委婉客气，相当于can；could也可表示惊讶怀疑，不相信。can’t和couldn’t一般用于否定句和疑问句中。eg：Hecouldn’tbeathief.

can表示推测时，常用于否定句、疑问句中，can’t意为“不可能；应该不是”。常用句型为:''can/can’tbe+表语''意为''（不）可能……''，表示对现在情况的推测。

eg:Thatcan’tbeMaria,becauseshe’sinhospital.

There’ssomeoneoutside.Whocanitbe?could/might:如果表示推测的把握性不是很大时，用could或might。它们常用于肯定句或疑问句中，意为''也许;可能''。
