在英语中,助动词一般都无详细意义,重要包含:be,have,do,will和shall,而情态动词有详细的词义,可是它们都不克不及零丁作谓语,必需和其他动词一块儿组成谓语。本章从情态动词(如can,may,must等)的用法讲授入手,再深刻到句子,如对Will you…和Shall I…等句型的解析。

典范例句:1.He is listening to music.(他正在听音乐。)

典范例句:2.I can speak English fluently.(我会讲一口流畅的英语。)

1.助动词和情态动词

1.助动词和情态动词的界说

在英语中,助动词一般没有词义,重要帮忙组成谓语,暗示时态、语态、组成疑难及否认@情%hC5Hx%势或增%g63vi%强@语气。情态动词与助动词分歧,它有词义,但它也和助动词同样,不克不及零丁作谓语,必需和其他动词一块儿组成谓语。此外首要的一点是情态动词没有人称和数的变革,厥后必需跟动词真相。

His brother doesn’t like playing basketball.(他哥哥不喜好打篮球。)(暗示否认)

I did go to see him,but he wasn’t in.(我确切去探望他了,但他不在家。)(增强语气)

Have you seen the film?(你看这部片子了吗?)(暗示时态)

()Maria types well.(×)Maria cans type well.

()Maria can type well.(×)Maria can types well.(玛丽亚打字打得很好。)

阐明:当主语是第三人称单数(如Maria)时,can的后面不克不及加s;也不克不及在举动动词后加s,必需用动词真相。

2.助动词和情态动词的种类

(1)助动词的种类

A.be(am,is,are,was,were,been,being)

助动词be与如今分词连系,可以组成举行时态(拜见(第13章 动词的举行时));与曩昔分词连系,可以组成被动语态(拜见(第16章 被动语态))。

Carl is playing badminton with Linda.(卡尔正在和琳达打羽毛球。)

Many people were killed in the 1976 Tangshan Earthquake.

(很多人在1976年的唐山地动中丧生。)

B.have(has,had,having)

助动词have与曩昔分词连系,可以组成完成时态(拜见(第15章 动词的完成时))。

I have read today’s newspaper.(我已读过今天的报纸了。)

Ketty has seen the Backstreet Boys in a concert in Beijing.

(凯蒂已在北京的一场音乐会上见事后街男孩了。)

C.shall(should),will(would)

助动词shall和will与动词连系,可以组成未来时(拜见(第14章 动词的未来时))。

We shall be very happy to see you.(咱们见到你会很欢快的。)

I will make Charlie a chocolate cake tomorrow.(我来日诰日将为查理建造一块巧克力蛋糕。)

D.do(does,did)

助动词do与其他动词连系,可以组成否认句和疑难句。

I don’t like having a barbecue in hot weather.(我不喜好在酷热的气候吃烧烤。)

Do you always forget to bring your bus card?(你常常健忘带公交卡吗?)

(2)情态动词的种类

英语的情态动词重要有can,could,may,might,must,have to,will,would,shall,should,ought to,had better,need,dare等,用来暗示哀求、义务、奉劝、猜测、建议、收罗对方定见也许可等。如下各节将重点讲述一些情态动词的用法。

2.can(could),may(might),must,need

can,may,must是三个最首要的情态动词,它们的根基句型以下所示:

必定句:主语+can,may,must+动词真相+……

否认句:主语+can,may,must+not+动词真相+……

疑难句:Can,May,Must+主语+动词真相+……?

need也能够作情态动词,一般用于否认句和疑难句中。

1.can,may,must的必定句

Vince can speak English and a little German.(文斯会说英语和一点儿德语。)

There may be a shower,so bring an umbrella with you.(可能会有阵雨,带上伞吧。)

We must study hard.(咱们必需尽力进修。)

(1)can的必定句

A.can暗示能力、允许、可能性。暗示能力时一般译为“能;会”,即有这类能力,尤指生下来就具有的能力。

To妹妹y can play the trumpet and draw pictures.(汤米会吹小号和画画。)

A robot can do many different things.(呆板人能做很多分歧的事变。)

They can do some shopping in Pedestrian Street of Nanjing Road.

(他们可以在南京路步行街购物。)

Butterflies can see more colours than human can.(胡蝶比人类能看到更多的色彩。)

首要:当can暗示能力时,may和must都不成以取代它。

B.can只有如今式can和曩昔式could,在暗示其他时态时,可以用be able to来取代。

I could (=was able to)(曩昔时)send e-cards before having the computer lessons.

(在学计较机课以前我就会发送电子贺卡。)

He has been able to(如今完成时)make a homepage and do online shopping on the Internet.

(他已会在互联网上建造主页和举行网上购物了。)

Perhaps people will be able to(未来时)live on the moon in the future.

(未来人们可能会在月球上糊口。)

比力:be able to可用于各类时态

can/could暗示能力时,可用be able to取代。can只有如今式和曩昔式,而be able to可以用于各类时态。

I can (=am able to) use the microwave oven and the toaster.(我会用微波炉和烤箱。)

(2)may的必定句

may评论辩论可能性,表猜测,译为“可能;或许”。may的曩昔式为might,一般用于必定句。

I may go to Vienna one day.(未来有一天我可能去维也纳。)

He asked if he might leave fifteen minutes earlier.(他问他是不是可以提早15分钟分开。)

(此句中的might是may的曩昔式)

You might like to buy a railcard to travel around the country.

(说不定你愿意买张火车优惠卡周游该国。)(might在这里暗示猜测,不暗示曩昔时)

阐明:might暗示的可能性比may要小。

(3)must的必定句

A.must暗示有做某一动作的需要或义务,译为“必需;应当”。

You must cut off the electricity before you change the bulb.(换灯胆前你应当堵截电源。)

You must put the meat in the fridge in su妹妹er.(炎天你必需把肉放进冰箱里。)

You must climb mountains with a partner.(你必需和一名同伴一起登山。)

弥补:You must…句型

You must…句型的意思与祈使句不异。

You must turn left.=Turn left.(你必需向左转。)

B.must暗示有掌控的果断或猜测,译为“必定;准是”,这类环境一般只用于必定句中。

The hair band must belong to Carolyn.(这根发带必定是卡罗琳的。)

The notebook must be Kathy’s.It has her name on it.

(这个条记本必定是凯西的,上面有她的名字。)

(暗示猜测时,must的语气比may和might要必定很多)

比力:must和have to的区分

must偏重于小我意愿和主观上的需要,have to偏重于客观上的需要。

I know I must study hard.(我晓得我必需尽力进修。)(句中夸大小我意愿,应当用must)

The last bus has gone.We have to take a taxi.(末班车已走了,咱们只能乘出租车了。)

(句中暗示客观环境,此时have to不克不及用must取代)

must只有一种情势,而have to则有较多的情势,可用于各类时态。若是must用于曩昔时态或未来时态时,则要用have to来取代。

My brother was badly ill,so I had to call the doctor in the middle of the night.

(我弟弟病得很利害,我只得三更里把大夫请来。)(一般曩昔时)

I haven’t got any money with me,so I’ll have to borrow some from my friend.

(我身上没有钱,只好向朋侪借点儿了。)(一般未来时)

must可用于间接引语中暗示曩昔的需要或义务。

He said that they must work hard.(他说他们必需尽力事情。)

2.can,may,must的否认句

含有情态动词can,may,must的句子,只要在它们后面加之not,就酿成了否认句。

I can not cook or play chess.(我不会烹调和下象棋。)

You may not leave now.(你如今不成以走。)

You must not talk with food in your mouth.(嘴里有食品的时辰不要措辞。)

(1)can的否认句

can的否认式是can+not,一般写成cannot,缩写为can’t,读作[kɑ:nt],译为“不会;不克不及;不成能”。

She can’t play basketball.(她不会打篮球。)

He can’t be a bad man.(他不成能是坏人。)

(can暗示猜疑或不愿按时,用于否认句及疑难句中)

He couldn’t be a bad man.(他不大多是坏人。)

(could有时只暗示猜疑、猜测水平,不暗示时态)

(2)may的否认句

may not也能够暗示“不成以”,但零丁利用的环境其实不多,大大都环境下用于答复疑难句。

A:May I come in?(我可以进来吗?)

B:No,you may not.=No,you mustn’t.(不,你不成以进来。)

(3)must的否认句

must的否认式是must+not,缩写为mustn’t,读作[msnt],译为“不成以;必定不……”,暗示强烈的语气。

You mustn’t smoke here.It’s too dangerous.(太伤害了,你绝不克不及在这儿抽烟。)

You mustn’t switch it off.(你们不要把它关掉。)

They mustn’t take any book out of the room.(他们不成以从房间里拿走任何书。)

弥补:You must not…句型

You must not…这一句型和否认的祈使句的意思一致。

You mustn’t break anything.=Don’t break anything.(万万不要冲破工具。)

3.can,may,must的疑难句

Can I keep the file for future use?(我可以保留这份文件留做未来利用吗?)

Must I carry so much water?(我必定要带这么多水吗?)

(1)can的否认句

疑难句型:Can+主语+动词真相+……?(……可以/会/能……吗?)

必定答复:Yes,…can.(是的,……可以/会/能。)

否认答复:No,…can’t.(不,……不成以/不会/不克不及。)

A:Can you play the piano?(你会弹钢琴吗?)

B:Yes,I can.(是的,我会。)/No,I can’t.(不,我不会。)

Can I join the team?(我可以参加这个团队吗?)

Could they win the game?(他们可能赢这场角逐吗?)

(could在这里暗示猜测,不暗示曩昔时)

2.may的疑难句

疑难句型:May+主语+动词真相+……?(……可以……吗?)

必定答复:Yes,…may./Sure./Certainly.(是的,可以。)

否认答复:No,…may not.(不,……不成以。)/No,…mustn’t.(不,……绝对不成以。)

A:May I turn on the light?(我可以开灯吗?)

B:Yes,you may./Yes,please./Certainly./Sure.(是的,可以。/可以,请打开。/固然可以。/可以。)

B:No,you may not./I don’t think you can.(不,不可。/我想不可。)

A:May/Might I watch TV?(我可以看电视吗?)

B:Yes,sure.(固然可以。)/B:No,you mustn’t.(不,绝对不可。)(口吻果断)

弥补:May…?句型另有以下答复方法:

Yes,of course.(是的,固然可以了。)/Yes,certainly.(是的,固然可以了。)/Sure.(固然。)

No,you must not.(不,不可。)(具备强烈制止的象征)

No,you can’t.(不,不可。)(白话中多采纳此句型)

比力:当暗示哀求允许时,can不如may正式。

Can I take your digital camera?

→May I take your digital camera?(我可以用你的数码相机吗?)(比力正式的用法)

当暗示哀求允许时,could比can加倍客套,此时,could不暗示曩昔时,只是使语气加倍委婉。

Could/Can I go to the Ocean Park tomorrow,Mum?(妈妈,来日诰日我可以去海洋公园吗?)

Could/Can we listen to music in the music room?(咱们可以在音乐室听音乐吗?)

与can和could同样,有时为了使语气加倍委婉一些,在疑难句顶用might取代may,此时might不是曩昔式。

A:May/Might I ask a question now?(我如今可以问个问题吗?)

B:No,you may not./No,you’d better not.(不成以。/不,你如今最佳别问。)

(3)must的疑难句

疑难句型:Must+主语+动词真相+……?(……必需……吗?)

必定答复:Yes,…must.(是,必需……)

否认答复:No,…needn’t./…don’t have to.(不,没必要了。)

A:Must I give the baby a bath now?(我如今必需给这个婴儿沐浴吗?)
B:Yes,you must.(是的,你必需。)

B:No,you needn’t./No,you don’t have to.(不,没必要了。)

4.can,could,may,might,must暗示猜测

它们均可暗示对产生或存在的事变的猜测。这里could和might不是曩昔时,猜测的语气不如can,may强;must暗示猜测时语气最强,意为“必定,判定”。

(1)暗示对如今及未来时态、动作的猜测

A.当暗示对如今及未来状况的猜测时,一般用can/could,may/might,must+动词真相。

Monica can’t be in the classroom.(莫妮卡不成能在课堂。)

You may come here whenever you like.(你想何时来就何时来。)

阐明:暗示@如%3i542%今或未%Z6g3w%来@的可能性,可用may/might+动词真相,might的可能性比may要小些。

B.当对如今及未来正在产生的动作举行猜测时,一般用can/could,may/might,must+be+doing(动词的举行式)。

A:Where’s Cindy?(辛迪在哪儿呢?)

B:It’s a fine day.She may/might be enjoying the sunshine on the lawn.

(今每天气好,她极可能在草坪上晒太阳呢。)

弥补:can在必定句中暗示比力一般的可能性,不暗示现实上正在产生或将要产生的详细可能性,这类可能性要用may来暗示。

Your sister can’t be touring Nanjing.I saw her just now.

(你姐姐底子不成能在南京游览,我方才还瞥见她呢。)

C.它们的猜测水平为:may/might暗示“有可能;大要”,might的语气比may要弱,至关于perhaps;can/could暗示“也许”,其可能性比may/might要小,至关于possibly;must的可能性最强,语气较必定。

(这个男孩子可能迷路了,这个处所欠好找。)

情态动词should,ought to均可以暗示奉劝、建议,一般环境下可以通用。在暗示请求、号令时,…had better(最佳)的语气比…should(应当)强。
