专题九 情态动词

情态动词知识点九年级上情态动词是英语中的一类特殊动词形式，用来表示说话人对某个动作或状态的态度、能力、推测等。

情态动词有一些固定的语法用法和含义，九年级上册英语教材对情态动词的学习内容涉及到了基本用法、否定和疑问形式、可能性和推测以及应用于口语交际中的实际语境等方面。

下面将对这些知识点进行详细论述。

一、基本用法情态动词包括can、could、may、might、will、would、shall、should、must等。

它们一般后面跟动词原形，表示不同的情态含义。

例如，can用来表示能力、许可或可能性，如"I can swim."（我会游泳）；may用来表示可能性或许可，如"It may rain tomorrow."（明天可能下雨）；must用来表示必须或推测的肯定，如"We must finish our homework before the deadline."（我们必须在截止日期前完成作业）。

二、否定和疑问形式情态动词的否定形式是在其后面加not，如can not、could not 等。

疑问形式是将情态动词放在句子开头，如Can you swim?（你会游泳吗？）Could he come to the party?（他能来参加派对吗？）三、可能性和推测情态动词也被用来表示可能性或推测。

may和might用来表示可能性，常用于猜测或询问某事是否可能发生，如"I may go to the party tonight."（可能我今晚去派对）；might还可以表示对过去的推测，如"He might have forgotten his keys."（他可能忘记带钥匙了）。

will和would用来表示根据某种迹象或情况的推测，如"Itwill rain soon. Look at those dark clouds."（天很快就要下雨了，看看那些乌云）。

（超值精品）2013届英语科5年高考3年模拟专题九情态动词和虚拟语气一、情态动词情态动词只有情态意义，即它所表示的是说话人对动作的观点，如需要、可能、意愿或怀疑等。

1. 情态动词没有实义动词的各种变化，只有could, would, had to, m ight等几个过去式。

其它如must, ought to 等的过去式皆与现在式同形。

2.大多数情态动词有多个意义。

如can可表“能够”“可能”“允许”等。

3. 在用法上，情态动词与助动词一样，须后接动词原形，构成谓语动语。

4. 情态动词有can，could, may, might, will, would, shall, should, o ught to, must, need, dare, used to 共十三种形式，不同的情态动词所表示的意义并不是相互排斥的，同一个意义常常可以由几个不同的情态动词以相同或不同的程度表示出来。

另一方面，同一个情态动词在同一个句子中可能表示不同的意义，在没有上下文的情况下，句子可能出现歧义。

如：He can’t come.他不能来。

句中can’t既可能表示说话人不允许，又可能表示主语无能力。

情态动词在表示多种意义的同时，相互之间既有联系，又有区别，前十个情态动词的联系大体围绕着两个方面：一是行为的自由（包括能力、允许和义务），二是推测。

它们之间的区别则体现在行为自由程度（degrees of freedom to act）的大小，和推测把握性的大小。

在这两个方面，最小和最大的都是might和must，如：You might d o it for me, please. 请你为我做这件事。

（近似请求的命令）You must do it for me. 你必须为我做这件事。

（不容违抗的命令）That might be Tom. 那或许是汤姆。

（把握性最小）That must be Tom. 那肯定是汤姆。

（抉择性最大）（1）Can / could的用法1． 1．表能够。

语法专题九情态动词和虚拟语气[考点解析]一情态动词1.can与culd的用法表示“能力, 许可, 可能性等. 在口语中can可以代替may表示许可, 而may比较正式;could可以代替can, 表示语气较为婉转. 例如:He is only four, but he can read.Can/ Could/May I come in?Can the news be true?2.may与might的用法表示许可或征询对方许可, 有“可以”的意思. 用作此意时, 它的否定形式可以用may not;但表示“不可以, 禁止, 阻止”等时常用must not(mustn’t)代替may not. 例如:You may go now. He said that I might use the telephone.---May I watch TY after supper? ---Yes, you may./No, you mustn’t(may not/had better not).表示可能性, 有或许, 可能”的意思, may或might+动词原形都可以表示可能性. 用might 则语气更加不肯定. 例如:They may/might have a lot of work to do.3.must与have to的用法must表示“必须, 应该”. 否定形式must not(mustn’t)表示“不应该, 不许可, 不准, 禁止”等. 在回答must的问句时, 否定式常用need not(needn’t)或don’t have to表示“不必”. 而不用must not, 因为must not表示“不可以”. must表示“一定, 必定”等推测意义时, 一般只用在肯定句中. 例如:The work must be finished as soon as possible.---Must I be home before eight o’clock?---Yes, you must./ No, you needn’t(don’t have to).Have to表示“必须, 不得不”, 在这个意义上与must很接近, 但must表示的是说话人的主观看法, 而have to表示的却是客观需要. have to比must有更多的形式. 例如:The TV set is broken. I have to buy a new one.The students will have to know how to use the computers.4.shall与should的用法在疑问句中, shall用来征询对方意见或请求指示, 用于第一, 三人称. should作为情态动词, 表示“劝告, 建议”, 常译作“应该”. 例如:Where shall I wait for you? You should keep your promise5.will与would的用法will表示“意志, 意愿”, 可用于多种人称, 在疑问句中用于第二人称, 表示询问对方的意愿或向对方提出请求. would是will的过去式, 表示过去时间的“意志, 意愿”, 可用于多种人称. 若表示说话人的意愿或向对方提出请求, 语气比will婉转, 指现在时间. 例如:I will tell you all about it. He won’t go with us.Would you like some coffee?6.need的用法用作情态动词时, need表示“敢; 敢于”, 主要用于疑问句, 否定句和条件从句中, 一般不用于肯定句. 例如:You needn’t come so early7.dare的用法dare用作情态动词时, 和need一样, 也是主要用于疑问句, 否定句和条件从句中. 例如: He daren’t speak English before such a crowd, dare he?8.ought to的用法ought to表示“应该” (与should同义, 只是语气稍重一些), 也可表示推测. 例如:You ought to take care of him. He ought to be home by now.ed to的用法表示过去的习惯动作或状态(现在已不复如此).例如:---Did you use to go there to see your brother? /Used you to go there to see your brother?---Yes, I did(used to). /No , I didn’t (usedn’t)10.had better的用法表示“最好(做……)”. 例如:We had better go now. Breakfast had better be eaten before 8 o’clock.情态动词用法归纳:二虚拟语气虚拟语气在虚拟条件中的运用(1)表示与现在事实完全相反的假设用以表示与现在事实相反的假设或现在实现可能性不大的情况. 条件从句用动词过去式(be 多用were), 主句用would/should/could/might+动词原形. 例如:If I were a bird, I could fly.如果我是一只鸟儿的话, 我就能飞了.(2)表示与过去事实完全相反的假设条件从句用had+过去分词, 主句用would/should/could/might+ have+过去分词. 例如:It we had started earlier, we should not have missed the train.如果我们早点出发, 就不会错过这列火车了.(3)表示与将来情形相反的假设或极少有可能实现的情况条件从句用动词过去式, should+动词原形, were to+动词原形, 主句动词用would/should/could/might+动词原形. 例如:If Professor Li should have time tomorrow, we could ask him questions.如果李教授明天有时间的话, 我们就可以问他问题了.书面语中, 上述三种时态的虚拟句中, 如果从句里含有should, had, were或其他助动词, 则可将从属连词if省去, 将助动词或情态动词放在句首形成部分倒装. 例如:Were he in your position, he’d have done the same.如果他在你的位置上, 他也会那么做的.2.错综时间虚拟句通常情况下, 在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间, 这时要根据上下文的意思采用不同的谓语动词形式, 例如;(1)If I were you, I would have taken his advice. (从句指现在, 主句指过去)如果我是你的话, 我就接纳他的建议.(2)If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去, 主句指现在)如果今天早上带上雨衣的话, 我现在就不会淋湿了.3.含蓄条件句有时假设的情况并不以条件从句表示, 而是暗含在上下文中, 比如通过介词短语来表示. (1)But for your advice, I could not have done it so successfully.要是没有你的建议, 我就不会成功(2)The changes could not have taken place without the open-door policy.要是没有开放政策, 就没有这些变化.(3)I was so busy then, otherwise, I would have gone to help him.那时我太忙了, 否则我就去帮他了.4.虚拟语气在某些从句中的应用(1)在wish, suggest, order, demand, propose, command, request, require, insist, desire, urge动词的宾语从句以及would rather后, 要用“(should)+动词原形”来表示愿望, 建议, 命令, 要求等; 由上述动词派生或转化的名词的同位语从句或表语从句中也要用相应的虚拟形式.像suggestion, proposal, plan, motion, recommendation, demand, order, desire, request, requirement, insistence, advice, decision等词.(2)在It is/was+某些形容词+that从句的句型中, that从句中的谓语动词常用虚拟语气, 即“should+动词原形”表示惊奇, 遗憾, 怀疑, 不满等。
