情态动词特殊用法大集合

情态动词除了基本的用法以外还有许多特殊之处,列举如下:

1.can和could

⑴Can 和could 可以表示某人或某物一时的特点,表示“客观有可能”可以翻译为“有可能,有时会”。

It can be very warm in this area 。这个地区有时可能非常暖和.

He can be very friendly at times 。他有时会非常友好。

⑵can表示能力时,可以与be able to 换用。但是在将来时和完成时中必须用be able to ;表示经过努力而成功地办到了某个具体的事情时,只能用be able to ,不可以用can。这种用法的be able to 相当于succeed in 或manage to。

I am sure we shall be able to get you a job soon 。(不能用can)

He has been able to finish the work on time。(不可用can)

After years of hard work he was able to win the prize 。(不可以用could)

He could't climb the mountain 。(没有能力爬,因而也没有爬)

He was not able to climb the mountain 。(尝试爬过,但是没能爬上去)

另外:

①对Were you able to find the pen?做否定回答应该用:No, I couldn't(find it ).不能说:No, I wasn't

able to find it.

②could 可以用来表示过去习惯性动作的完成,而was able to 却没有这种用法。

I could run after a bus and catch it twenty years ago ,I can't do that now 。

二十年前,我能在后面跑着追上公共汽车,现在不行了。

③cannot /can't 与too/over(‐)/enough /perfectly /sufficiently 等词连用,意思是

“越…越…”“无论怎样……也不为过”、“决不会……够(过)”。

You can't praise him too much 。你无论怎样称赞他都不过分。

You cannot be over careful 。你越细心越好。

I can't thank you enough 。我对你感激不尽。

This point cannot be overemphasized 。这一点无论如何强调都不过分。

④“cannot wait 不定式”意思是“be eager to ……急于做”,表示强调的肯定意思。

I cannot wait to read the book 。我非常渴望读这本书。

He couldn’t wait to see her 。他渴望见到她。

练习题:

Please remind your grandpa to take medicine on time,for a man of his

age_______ be very forgetful 。

A.should B. must C. shall D. can

②You cannot be_______ careful when you drive a car .

A.very

B.so

C.too

D.enough

③The car broke down on the way ,but we_____get out of the desert at last.

A.might

B.would

C.were able to

D.could

2.must有一种含义:“偏要”“硬要”。表示说话人对句子主语所发出的动作或行为是不希望的、不满的甚至是生气的。

通常指令人不愉快的事情。must用于第二人称时,常常含有讽刺挖苦的意思:

Why must you be so stubborn (固执)?

He must come and worry her with questions ,just when she was busy cooking the dinner 。

If you must smoke, at least you could use an ashtray(烟灰缸).

As I was sitting down to lunch ,the electric bell must ring 。

Why must you be so late ?你为何非要这么晚来呢?

练习题:

①Why _______you always interrupt me ?

A. can

B. will

C. may

D. must

②Naturally ,after I told her what to do ,my daughter _______go and do the opposite !

A .may B.can C. must D. should

注意:(1)must 可以表示客观必然性,意思为“必然(会),总是会”,而have to 则不可以这样用。

All men must die 。人固有一死。

Competition must happen 。竞争总会发生。

Truth must be out 。真相总会大白。

There must be a day for revenge 。总有报仇的那一天。

(2)对must 所在句子变反意疑问句时,应注意以下习惯搭配:

①must 作“必须”解时,反意疑问句中重复must 。

All the children must respect their parents ,mustn’t they ?

孩子必须尊敬父母,对吗?

②“must be ”表示推测时,反意疑问句用be 的适当形式。

You must be thirsty ,aren’t you ?你一定渴了,是吗?

③“must have done ”表示推测时,附加疑问句一般用have 或 has ,但是有明确表示过去

的时间状语时,反意疑问句用过去时态。

He must have finished the work ,hasn’t he ?

He must have gone abroad last week ,didn’t he ?

You must have been told about it that day ,weren’t you ?

https://www.360docs.net/doc/566766803.html,ed to 的意思是“过去常常”,已经含有 always, often, sometimes, from time to time等意思,但是它却可以和它们连用。

He always used to come by bus. 他过去总是坐公共汽车来。

He often used to work late at night.他过去经常工作到深夜。

She always used to get up at four o'clock in the morning.她过去总是早晨4点起床。

但是used to 不可以与表示具体次数或一段时间(即特定的时间段)的词语连用。

He went to abroad three times.

He lived in the countryside for three years.

但是可以和过去确定的时间壮语连用。

He used to live here in 1995。

He used to be devoted to her when she was a little girl.

另:would 和used to 的区别如下:

两者都可以表示过去的习惯性动作。但是would 只强调过去特定情况下的习惯性动作(由动态动词表示),单纯的过去和现在无关;而used to 即可以强调过去的习惯性动作(由动态动词表示),也可以强调过去的事实或状态(由静态东此表示),且与现在形成对比,即可表示持续的状态,也可表示过去重复的行为。

I used to have an old car 。过去我有一辆旧轿车。

I didn't use to like opera ,but now I'm getting interested 。

我过去不喜欢歌剧,但现在逐渐有了兴趣。

上面两句话的动词均是静态动词,说明过去的事实或状态,不能用would 代替used to 。

但是would可以和sometimes/now and then/from time to time 等词组(表示过去有时或偶尔的时间状语)连用。

She would sit there for hours sometimes, doing nothing at all .

他有时一连坐好几个小时,什么事情也不干。

练习题:

When he was there ,he_______go to that coffee shop at the corner after work every day .

A.would

B.should

C.had better

D.might

4.shall可以用在第二、三人称,要重读,不可以缩写,表示说话人的意图、意志、允诺、命令、命运或必然结果等;在法律、条约、协定等文件中可以表示义务、规定等。

You shall have a lot of money .(意图/允诺)你会有很多钱的。

情态动词must用法详解

情态动词must用法详解 (1) 表示“必须” 此时可用于肯定句、否定句或疑问句,用于否定句时,mustn’t的意思是“一定不要”“不能”,而不表示“不必”。如: Water must be pure if it is to be drunk. 水如供饮用必须净化。 Must I finish the work tonight? 我必须今晚完成这项工作吗? Adverbs mustn’t be put between the verb and the object. 副词不能放在动词和宾语之间。 must主要表示现在或将来,但在间接引语中也可表过去(=had to)。如: She asked her boss if she must (had to) work overtime. 她请示上司她是否要加班。 对于must开头的一般疑问句,若作否定回答,可以用needn’t,不能用mustn’t。如:“Must I clean all the rooms?” “No, you needn’t.” “这些房间我都得清扫吗?”“不必。” (2) 表示推测 意为“准是”“一定是”,通常只用于肯定句。若用于否定句或疑问句,则用can 代之。如: That can’t be the only way. There must be other ways of solving the problem. 那不可能是解决问题的唯一办法,肯定有另外的办法。 Jane’s light is on. She must be at home. She can’t be out. 简的房间里开着灯。她一定在家,不会出去的。 若要谈论过去或完成的情况,必须用“must+have+过去分词”。如: You must have mistaken my intention. 你一定是误会了我的意图。 She must have been very young when she got married. 她结婚时一定很年轻。 He must have come this way; here are his footprints. 他一定是走这条路来的,这里还有他的脚印呢。 They must have finished their homework, for they are playing happily on the playground. 他们一定是写完作业了,他们在操场上玩得多开心呢。 (3) 表示“偏偏” 有时must可表示某事发生得不早不迟,就在某个当紧的时候,多指某些不受欢迎的事情的发生。如: The car must break down just we were starting our holidays. 我们刚刚开始休假,汽车偏偏坏了。 Must you worry her with questions, just when she is busy cooking dinner? 她正忙着做饭你干吗偏偏问她问题? Just when I was busy, the neighbor must come and chatter. 正当我忙碌的时候,邻居偏偏过来聊天。 有时还可指主观上的偏执或固执,常可译为“偏”“偏要”。如: After I gave her my advice,she must go and do the opposite. 在我给她出主意之后她偏要反着干。 Must you make so much noise? 你就非得弄出这么大的声音吗? (4) must 与have to 的区别 两者都表示“必须”,但must 侧重于说话者的主观看法,认为有必要或有义务去做某事;have to 则重于客观需要,含有“不得不”“被迫”之意。如: Everyone must keep the law. 人人都要守法。 The last train has gone. We’ll have to walk home. 最后一班车已经开了,我们得走回家了。

We could go there this summer. 今年夏天我们可能要去那儿。 注:can 有时也用于肯定句中表示推测,主要用于表示理论上的可能性(即从理论上看是可能的,但实际未必会发生),或表示“有时”之意。如: Even experienced teachers can make mistakes. 即使是有经验的教师也可能出错。 She can be very unpleasant. 她有时很令人讨厌。 (2) 从时间关系看,对现在或将来情况作推测,后接动词原形;对正在进行的情况作推测,后接be doing 结构;对过去情况作推测,后接动词完成式。如: He could have gone home. 他可能已经回家了。 He can’t [couldn’t] have understood. 他不可能理解了。

Why does he know this? Can [Could] someone have told him about it? 他怎么知道? 会是哪个人告诉他了吗? (3) “could+完成式”除表示对过去的推测外,还有以下重要用法: ①表示过去没有实现的可能性,常译为“本来可以”。如: I could have lent you the money.Why didn’t you ask me? 我本来可以借这笔钱给你的。你为什么不向我提出? ②用来委婉地责备某人过去应该做某事而没有去做,常译为“本来应该”。如: You could have helped him. 你本来应该帮助他的。 ③表示“差点儿就要”。如: I could have died laughing. 我差点儿笑死了。 2. may / might用于表推测的用法 表示推测,两者都可用,只是might 比may 语气更不确定,表示的可能性更小。 (1) 在句型使用方面:两者均可用于肯定句和否定句,但用于疑问句时,may通常不用于句首,但可用于疑问句的句中(如特殊疑问句等),而might尽管可以用于疑问句的句首,但不算普通,通常会改用其他句式(如用could等)。如: He may [might] know the answer. 他可能知道答案。

情态动词的一些特殊用法

情态动词的一些特殊用法 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。 Y ou look so sleepy. Y ou must have sat up late last night. 你看上去这么困倦, 昨晚一定睡得很晚。 I mailed that letter a week ago. He must have received it. 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”。 Y ou had only a little egg at breakfast today. Y ou must be hungry now. 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。 其它情态动词如may (might), should (ought to), can(could), need的用法分别如下: 二、may(might) may(might) + have + -ed 分词: 用于肯定句和其它否定句, 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。 They may have derived inspiration from these words. 他们可能从这些话语中获得了灵感。 Our manager may (might) have gone to Guangzhuo attending Spring Fair there last week. 我们经理可能已于上周去广州参加春交会了。

情态动词,特殊疑问句,一般疑问句

情态动词(Modal [‘modl:] verbs) 不能独立作谓语,只能和行为动词一起构成谓语。情态动词用在行为动词前,表示说话人对这一动作或状态的看法或主观设想。 情态动词主要有下列:can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not. 情态动词的特点: 情态动词无人称和数的变化,情态动词后面跟的动词须用原形,否定式构成是在情态动词后面加"not"。 个别情态动词有现在式和过去式两种形式,过去式用来表达更加客气,委婉的语气,时态性不强,可用于过去,现在或将来。 情态动词属非及物动词,故没有被动语态。

一般疑问句General ['d?enr?l] Questions 1.基本结构: ①谓语动词是助动词(do, have和be)、情态动词时,只要直接把这些词置于句首,句末改成问号。★be + 主语+ 其它部分 ★情态动词+ 主语+ 动词原形+ 其它部分 ★肯定回答用“Yes,主语+be\情态动词.”,否定回答用“No,主语+be\情态动词+not.”。

②谓语动词是行为动词时,必须在句首加上助动词Do、Does、Did,句子中谓语动词必须用原形。 ★助动词+ 主语+ 动词原形+ 其它 Do your parents like English Yes,they do. / No,they don’t ③注意:在把肯定句改成否定句或一般疑问句的时候, already要改成yet,some、something、somebody等分别改成any、anything、anybody等。在改成否定句的时候注意把too改成either, both改成neither, all改成none等.把第一人称I、we改成第二人称you。 Are you from Japan﹖Yes, I am./ No, I'm not. Is her sister doing her homework now﹖Yes, she is./ No, she isn't. Does he work in a bank﹖Yes, he does./ No, he doesn't. 2.将陈述句变为一般疑问句 ①含be动词或情态动词的句子(秘诀:一调二改三问号) 一调:即把句中的be或情态动词调到主语前; 二改:改换主语称谓,即将句中的主语I\my \mines\we\our\ours等第一人称分别改为相应的第二人称you\your\ yours等; 三问号:句末的句号改为问号。如: I am an English teacher. →Are you an English teacher We can speak English fluently. →Can you speak English fluently ②含行为动词(或称为实义动词)的句子(秘诀:一加二改三问号) 一加:即在句首加助动词Do或Does; 二改:①把谓语动词改为原形;②、改换主语称谓(同第一组); 三问号:句末的句号改为问号。 We read English every morning. → Do you read English every morning Tom’s father listens to English on the radio every evening. → Does Tom’s father listen to English on the radio every evening 特殊疑问句The special interrogative sentence 以疑问词开头,对句中某一成分提问的句子叫特殊疑问句。 疑问代词:what(什么)who(谁,作主语) which(哪个,在一定范围内选择) whose(谁的,指附属关系)whom(谁,作宾语) ②疑问副词:when(何时,询问时间)where(何地,询问地点) why(为什么,询问原因) how(如何,询问手段,方式,工具以及程度) 2.语序:
