初中英语语法之情态动词用法及练习题(含答案)

情态动词用法及练习题一、情态动词的概念:情态动词主要用以表明说话者对某一行为的态度和观点,主要包括揣测、判断、需要及各种意愿。

常见的情态动词有can、may、could、must、have to、should、would等。

二、情态动词的特征(1)情态动词本身有词义,但词义不完整,因此不能独立作谓语,只能和主要动词一起构成谓语。

例如:I can play the piano.( can play整体为谓语)(2)其后动词使用原形。

例如:You should lie down.(3)情态动词一般没有人称和数的变化(即不管是何人称,后面接的情态动词都不变)。

例如:I/She can sing.(4)它的否定式一般是在其后加 not构成,在一般疑问句中通常将其提到句首。

结构如下:①肯定句:主语+情态动词+动词原形+其他。

例如:He can swim.②否定句:主语+情态动词+not+动词原形+其他。

例如:He can't swim.③一般疑问句:情态动词+主语+动词原形+其他?Yes,主语+情态动词. No,主语+情态动词+not.例如:-Can he swim?-Yes, he can. No,he can’t.④特殊疑问句:特殊疑问词+情态动词+主语+动词原形+其他? 例如: -What can he do ?-He can swim.三.情态动词的用法(1)can的用法①表示“能力”Can you sing?你会唱歌吗?②表示客观条件允许You can listen to music here.你可以在这里听音乐。

You can’t park your car here. 你不能在此停车③can用在否定句和疑问句中时,有时表示说话人的怀疑、惊异、或猜测:It can’t be true.这不可能是事实Can it be true?这可能是真的吗?④.can的搭配用法:A.as +adj./adv.+as one can/could “尽可能,尽量……”,如:The man took his child to the hospital as quickly as he could.这个男人尽可能快地将孩子送去医院。

初一情态动词讲解及练习附答案

初一情态动词讲解及练习附答案

(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) 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。

Can只有一般现在时和一般过去式;而be able to则有更多的时态。

I’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 was able to go to the party yesterday evening in spite of the heavy rain.2) 表示请求和允许。

-----Can I go now? ----- Yes, you can. / No, you can’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。

---- Could I come to see you tomorrow? ---- Yes, you can. ( No, I’m afraid not. )3) 表示客观可能性(客观原因形成的能力)。

They’ve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least.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。

must,can(could),may(might)可以表示猜测,must表示肯定猜测,用于肯定句,肯定……一定……;can't表示否定猜测,肯定不……,另外can(could),may (might),表示可能性猜测,可能……根据I think,可知把握较小,根据I saw him go home a minute ago.可知第二句把握大,故选D。

初中英语情态动词练习50题

初中英语情态动词练习50题

初中英语情态动词练习50题1. We ______ swim when we were five years old.A. canB. couldC. can'tD. couldn't答案:B解析:根据“when we were five years old”可知是过去的时间,can 的过去式是could,所以用could,表示“能够”。

2. —______ you play the piano?—Yes, I can.答案:A解析:根据答语“Yes, I can.”可知问句用can 提问,意思是“能,会”。

3. She ______ speak English very well, but she can't write it well.A. canB. couldC. mayD. might答案:A解析:“speak English very well”表示一种能力,can 表示“能够,会”,符合句意。

它们具有以下特点:⑴它们必须与其他动词连用,即:情态动词+动词原形表示说话人对所述动作的看法,如需要、可能、意愿或怀疑等。

⑵绝大多数情态动词没有人称和数的变化,即第三人称单数不加-s(以be和have 开头的情态动词短语除外)。

⑶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】1. can的基本用法:⑴表示体力或智力上的能力,即“能够,会”,可与be able to转换。

例:He can speak English. = He is able to speak English.—Can you play basketball?— No, I can’t.如果表示将来具备的能力,要用will be able to。

例:If I have a good sleep, I will be able to do the problem.⑵表示许可,主要用于口语,书面语一般用may。

例:—Can we go home now, please?— No, you can’t.You can only smoke in this room.You can’t keep the library books for more than a month.⑶表示“可能”,与may同义,但一般用在疑问句中。

例:What can he possibly want?在否定句中,否定形式can’t表示推测“不大可能”。

例:Anybody can make mistakes.The news can’t be true.与第一、二人称连用时,还可以就可能的解决问题的方式或可能的行为提出建议。

在这里,也可用could使语气婉转。

例:Can / Could we meet again next week? 下周我们可以再见面吗?—What shall we do? 我们怎么办呢?— We can / could try asking Lucy for help. ——我们可以请露茜帮忙试试看。

You can / could help me with the cooking. 你可以帮我做饭。

2. may的基本用法:⑴表示“许可”,用can比较口语化。

例:You may / can come if you wish. 如果你想来,你就来。

You may not pick flowers in this park. 本公园内不许摘花。

(may not表示按规定不许可,如果用mustn’t则表示说话人不许可。

)我可以在这里抽烟吗?—mustn’t表示明确的禁止。

)⑵肯定句中表示推测,“可能”。

例:It may rain tomorrow. 明天可能会下雨。

The news may not be true. 这个消息可能不会是真的。

注意:如果例:Can it be true? 那会是真的吗?Who can he be? 他究竟是谁呢?⑶【注意】:……?—Yes, you —No3. must的基本用法:⑴表示必须,强调说话人的主观意志。

例:I must go now, or I’ll be late.You must be here by ten o’clock.【注意】:表示“必须“时,must,而不是mustn’t。

也就是:—Must I/we do it now?—Yes, you—No, you例:—Must I go with them?—No, you.⑵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…?,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。

⑴ 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】:I/we……?—Yes,—No, you⑵need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。

即如果物作主语,一般后用例如:I need to look up this word in the dictionary.My watch needs mending/to 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。

意思是“最好做某事;还是做某事比较好”。

例:You’d 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?Hadn’t we better tell her the truth? 我们是否最好不告诉她真相?7. could, should, would, might表示推测:①.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needn’t或don’t (doesn’t) have to。

如:We must obey the traffic rules. 我们必须遵守交通规则。
