如:

2)表示请求和允许。
-----CanIgonow?
-----Yes,youcan./No,youcan’t.
此时可与may互换。
在疑问句中还可用could,
might代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。
----CouldIcometoseeyoutomorrow?
----Yes,youcan.(No,I’mafraidnot.)
3)表示客观可能性(客观原因形成的能力)。
They’vechangedthetimetable,sowecangobybusinstead.
Thishallcanhold500peopleatleast.
4)表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。
Canthisbetrue?
Thiscan’tbedonebyhim.
Howcanthisbetrue?
二、may,might
1)表示请求和允许。
might比may语气更委婉,而不是过去式。
否定回答时可用can’t
或mustn’t,表示“不可以,禁止”。
----Might/MayIsmokeinthisroom?
----No,youmustn’t.
----May/MightItakethisbookoutoftheroom?
----Yes,youcan.(No,youcan’t/mustn’t.)
用MayI...?
征徇对方许可时比较正式和客气,而用CanI...?
在口语中更常见。
2)用于祈使句,表示祝愿。
Mayyousucceed!
3)表示推测、可能性(不用于疑问句)。
might不是过去式,它所表示的可能性比may小。
1.Hemay/mightbeverybusynow.
2.Yourmothermay/mightnotknowthetruth.
三、must,haveto
1)表示必须、必要。
Youmustcomeintime.
在回答引出的问句时,如果是否定的,不能用mustn’t(禁止,不准),而用needn’t,don’thaveto(不必).
----Mustwehandinourexercisebookstoday?
----Yes,youmust.
----No,youdon’thaveto/youneedn’t.
2)must是说话人的主观看法,而haveto则强调客观需要。
Must只有一般现在时,haveto有更多的时态形式。
1.Hisplayisn’tinteresting,Ireallymustgonow.
2.IhadtoworkwhenIwasyourage.
3)表示推测、可能性(只用于肯定的陈述句)
1.You’reTom’sgoodfriend,soyoumustknowwhathelikesbest.
2.Yourmothermustbewaitingforyounow.
四、need
1)need作情态动词用时,常用于疑问句、否定句。

1.Youneedn’tcomesoearly.
2.----NeedIfinishtheworktoday?
----Yes,youmust./No,youneedn’t.
注意:
对must构成的一般疑问句作否定回答只能用needn'
