Test 9 情态动词

情态动词的用法【用法讲解】考试要求：中考要求掌握情态动词在一般疑问句的问与答,理解情态动词表示猜测的用法及情态动词的被动语态应用.情态动词表示说话人对某一动作或状态的态度,认为“可能”，“应该”或“必要”等。

情态动词本身词义不完全,不能独立作谓语动词，必须和动词原形连用（ought除外)。

情态动词没有人称和单复数的变化。

常用情态动词有can(could），may(might），must, ought to，have to，need, dare, shall（should），will(would)。

1. 情态动词can 和could的主要用法（1）表示能力，意为“能，会”。

Can you swim? 你能游泳吗？His granny is over eighty but still can read without glasses。

他的奶奶虽然八十多岁了，但是仍旧不用戴眼镜能够阅读。

注意：can和be able to表示“能力”时的区别：can只有现在式和过去式两种形式,而be able to除了现在式和过去式,还有将来式和完成式等多种形式.She will be able to help you tomorrow afternoon。

明天下午她将能帮助你.This is the information that I have been able to get so far.这是我到目前为止能得到的信息。

（2）表示“许可，允许"。

can 和could没有时态上的区别，could比can在语气上更客气；在回答could引导的一般疑问句时要用can。

Could/Can you tell me the way to the railway station?你能告诉我去火车站的路吗？—Could I use your pen？我可以用你的钢笔吗？—Yes，of course you can。

是，当然你可以。

情态动词用法归纳情态动词有can （could）, may (might）， must, have to， shall （should， will (would), dare （dared)， need (needed)， ought to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， could1） can, could表示能力（体力、知识、技能）. Can you lift this heavy box？（体力）Mary can speak three languages。

（知识) Can you skate?（技能）此时可用be able to代替.用be able to改写上面三个句子。

Can只有一般现在时（can）和一般过去式（could）;而be able to则有更多的时态。

am/is/are able to（一般现在时）：I am able to do this job,其它几个自己改写was/were able to（一般过去式）： He was able to do this jobwill be able to（一般将来时）:I will(won't) be able to do this job this afternoonI'll not be able to come this afternoon.当表示“经过努力才得以做成功某事”时应用be able to，不能用Can.如：He can’t swim，but he is able to cross the river.2） can, could表示请求和允许。

—-———Can I go now? =May I go now?——-—- Yes， you can。

/ No，you can’t.=Yes,you may。

/No,you may not.此时可与may互换。

情态动词用法总结及相应练习在英语中，情态动词属于助动词。

除了作简略回答外，它们一般不能单独使用，它们必须与动词原形一起使用构成句子的谓语。

初中语法：情态动词知识点练习题一、情态动词单项选择题1．By the time he was only eight, Frank ________ speak both English and French.A．could B．must C．can D．may【答案】A【解析】【分析】【详解】句意：Frank只有八岁的时候，他就会说英语和法语了。

考查情态动词辨析。

could能、会，can的过去式；must必须、一定；can能、会；may可以、可能。

根据前句“By the time she was eight”可知，空处所在的句子应用一般过去时，表示有能力做某事，应用can的过去式could。

故选A。

2．—Is that red schoolbag Mary’s?—It ________ be hers. She hates that color.A．can’t B．may C．might D．mustn’t【答案】A【解析】【分析】【详解】句意：——那个红色书包是玛丽的吗？——不可能是她的。

她讨厌那种颜色。

考查情态动词。

can’t不能；may可以；might或许；mustn’t禁止。

根据“She hates that color.”判断，包不可能是玛丽的，表示否定的推测用can’t be。

故选A。

3．— Who is the woman _______ short hair?—I think she ________ Kate’s mother.A．has ; maybe B．with; maybe C．has; may be D．with; may be【答案】D【解析】【分析】【详解】句意：——那个短发的女人是谁？——我想她可能是凯特的妈妈。

考查介词和情态动词。

has有，动词； with有，介词；may be可能是，情态动词+动词原形； maybe或许，副词。

根据“Who is the woman”可知，此句已有谓语动词，因此用介词with表示“有……”；再者根据“she...Kate’s mother.”可知，此空缺少谓语动词，因此may be符合句意。
