情态动词本身有语义,表示说话人的语气或情态,但语义不完整,不能单独作谓语动词,一般只能与动词原形一起构成谓语动词。
现就考试中出现频率高的情态动词及其用法作些说明:
一、must
与must有关的题型经常与其后面应跟什么时态有关.在有must的句中,常?
表示说话人在进行依据较充分的推测。
至于用哪些时态,则有两个参考标准:
?
句中的时间状语和句间的关系。
Youlooksosleepy.Youmusthavesatuplatelastnight.
你看上去这么困倦,昨晚一定睡得很晚。
Imailedthatletteraweekago.Hemusthavereceivedit.
我一周前就发出了那封信,想必他一定收到了。
must+have+-ed分词:
用于肯定句,表示对过去情况的推测,意为“肯定,一定”。
Youhadonlyalittleeggatbreakfasttoday.Youmustbehungrynow.
Must加动词原形的进行式,表示对现在发生动作和事物的猜测,有“一定,准是”的意思。
其他情态动词如may（might）,should（oughtto）,can（could）,need的用法分别如下:
二、may（might）
may（might）+have+-ed分词:
用于肯定句和其他否定句,表示对已发生事情的不肯定的推测,意为“可能,大概”,其中might较may语气更弱,把握更小。
Theymayhavederivedinspirationfromthesewords.
他们可能从这些话语中获得了灵感。
Ourmanagermay（might）havegonetoGuangzhuoattendingSpringFairtherelastweek.
我们经理可能已于上周去广州参加春交会了。
三、should
除了其一般的用法以外,should也表示说话人的感情如愤怒,惊奇,失望等。
Iamsorrythatheshouldbesostubborn.
他居然如此固执,我对此感到很抱歉。
WhyshouldIgotherewhileshestayshome?
为什么我得去那儿,而她却能呆在家里?
should（oughtto）+have+-ed分词句型:
指过去的事情。
如果是肯定句,表示过去本应发生的事却没有发生,含“遗憾、责备、建议或指正”等意味;如果是否定句则表示已发生了本不该发生的事。
Youshouldhavetoldhimthepaintonthatseatiswet.
你本应告诉他座位上的油漆未干。
Theyshould'thaveleftsosoon.
他们不该这么早就离开。
四、can（could）
用于否定或疑问句中,后面跟动词原形的完成式时,表示对过去发生的事件的“怀疑或不肯定”。
could比can更表示说话人语气的不肯定。
Nobodycouldhaveforeseenallthis.
当时无人能预见到所有这一切。
Itcouldn'thavebeenMr.Smith.HehasgonetoChina.
不太可能是史密斯先生。
他已去了中国。
五、need
needn't+have+-ed分词:
表示过去做了但不必做的事情,意为“其实不必”。
Youneedn'thavewalkedup;youcouldhavetakenthelift.
你本不必跑上来,你本来可以乘电梯的。
Youneedn'thavewateredthevegetables,asitisgoingtorain.
你本不必给蔬菜浇水,因为天要下雨了。
