开头的情态动词短语除外）。在意义上，情态动词具有“多义性”。例：can既可表示能力，又可表示可能、允许等意义。【情态动词的基本用法】|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 1 页，共 8 页此文档仅供收集于网络，如有侵权请联系网站删除只供学习与交流1.can 的基本用法：表示体力或智力上的能力，即“能够，会”，可与 be able to

be late.You must be here by ten o clock.【注意】：表示“必须“时，must 的否定式为neednt，或 don t have to,而不是 mustnt。也就是：Must I/we do it now？Yes,you must.No,you needn t/dont have to.例：Must I go with them?No,you.表示 推测，一般只用于肯定陈述句,表示非常肯定。例：She didn t look at me.She must be angry.她不朝我看，一定是生气了。He is good at English.He must know the word.他英语好，准知道这个词。You must be Mr.Jones.想必您就是琼斯先生吧。4.have to 的基本用法：have to 可视为情态动词，但它与其他情态动词在用法上稍有不同。其他情态动词没有人称和数的变化，而have to 却有人称和数的变化，要视主语的不同而变化。例：I/You/We/They have to.He/She/It has to.You don t have to.Does she have to?have to=have got to，意思是“必须，不得不”。和 must 不同之处：must 强调主观需要have to 强调客观需要。例：Sorry,I have to leave now.对不起，现在我得走了。I ve got to go to a meeting.我得去参加一个会议。Will he have to work deep into the night?他将不得不工作到深夜吗？5.need 的基本用法：need 的基本词义是“需要”，它既可作情态动词，又可作实义动词。need用作 情态动词 时，只用于否定句和疑问句。它只有一种形式，后接动词原形。例：I don t believe you need worry.我相信你没有必要焦急。Need we go so soon?我们需要这么早就去吗？Yes,we must./No,we needn t.是的，必须。不，不必。So I needn t tell him,need I?所以我不需要告诉他，对吧？请比较以下两句话的不同意思：You needn t buy the coat.你没有必要买那件外衣。（你还没买）You needn t have bought the coat.你没有必要买这件外衣的。（而你却买了）【注意】：Need I/we？Yes，you must./No,you needn t/dont have to.need 用作实义动词时，有时态、人称和数的变化。如果 人作主语，一般后接带to 的动词不定式。即need to do sth；|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 3 页，共 8 页文档编码:CD2B2M4F5V3 HK5Q4T1Z8Y4 ZE7G6Q6B6G3文档编码:CD2B2M4F5V3 HK5Q4T1Z8Y4

be mended.我的手表需要修理了。We don t need to work today.(=We needn t work today.)Does he need to go right now?(=Need he go right now?)6.had better 的基本用法：had bette r 常略作 d better。现代语法认为它是一个助动词，因为它后接不带to 的动词不定式。had better do sth意思是“最好做某事；还是做某事比较好”。例：Youd better get some sleep.你最好睡一会儿。You d better not do that again.你最好别再做那件事。What had we better do now?我们现在怎么做才好呢？Hadnt we better tell her the truth?我们是否最好不告诉她真相?【注意】：Youd better.表示劝告或委婉的命令，对长辈不宜使用。7.could,should,would,might表示推测：.must 多用于肯定句中表示把握性极大的推测,意思为“一定、肯定”。如:You have worked hard all day.You must be tired.你已辛苦工作一整天了,一定累了。The book must be his.His name is on the cover.这本书一定是他的,封面上写着他的名字。【注意】must 不表推测时,在肯定句中意思为“必须(强调内在的职责)”,在否定句 中意思为“不许、禁止”,以它开头的疑问句否定回答常用neednt或 dont(doesn t)have to。如:We must obey the traffic rules.我们必须遵守交通规则。Cars mustn t be parked here.此处严禁停车。Must we hand in the papers this week?我们必须本星期交论文吗?No,you needn t.不,你们不必(本星期交)。.can/could 多用于 否定句、疑问句或感叹句 中表示 推测、怀疑,两者在时间上没有差别。用can 时不相信的程度更强一些,cant常常译为“不可能”。如:The man under the tree cant be Tom.He s gone to England.这个人不可能是Tom,他已经去英国了。Can it be true that he was fooled by a five-year-old boy?他被一个五岁的孩子愚弄了,这能是真的吗?Could this be an excuse?这会不会是个借口?How can you be so careless!你怎么这样粗心!.may/might多用来表示 把握性不大的推测,意思为“也许、可能”,might比 may 的把握性更小一些。may not 在否定句中常常译为“可能不”。(注意区分“不可能”与“可能不”在把握性大小上的差异。)如:Mr.Wang may know Professor Lis telephone number.王先生也许知道李教授的电话号码。This might be the key Tom has been looking for.这可能就是汤姆一直在找的钥匙。She may not be there today.今天她可能不在那儿。二、典型例题【中考链接】（）1 Who is the man over there?Is it Mr.Li?No,it _ be him.Mr.Li is much taller.A.mustnt B.may no
