Unit9语法篇
情态动词用法归纳
情态动词有can（could）,may（might）,must,haveto,shall（should,will（would）,dare（dared）,need（needed）,oughtto等。
情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语
一、can,could
1）表示能力（体力、知识、技能）。
Canyouliftthisheavybox（体力）
Marycanspeakthreelanguages.（知识）
Canyouskate（技能）
此时可用beableto代替。
Can只有一般现在时和一般过去式；而beableto则有更多的时态。
I’llnotbeabletocomethisafternoon.
当表示“经过努力才得以做成功某事”时应用beableto，不能用Can。
如：
Hewasabletogotothepartyyesterdayeveninginspiteoftheheavyrain.
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．heplayisn’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、dare,need
1）dare作情态动词用时,常用于疑问句、否定句和条件从句中,过去式形式为dared。
1．HowdareyousayI’munfair
2．Hedaren’tspeakEnglishbeforesuchacrowd,darehe
3．Ifwedarednotgotherethatday，wecouldn’tgetthebeautifulflowers.
2）need作情态动词用时,常用于疑问句、否定句。
在肯定句中一般用must,haveto,oughtto,should代替。
1．Youneedn’tcomesoearly.
2.----NeedIfinishtheworktoday
----Yes,youmust./No,youneedn’t.
3）dare和need作实义动词用时，有人称、时态和数的变化。
在肯定句中，dare后面常接带to的不定式。
在疑问句和否定句中，dare后面可接带to或不带to的不定式。
而need后面只能接带to的不定式。
