情態(tài)動(dòng)詞特殊用法
情態(tài)動(dòng)詞除了基本的用法以外還有許多特殊之處，最基本的用法讀者可以結(jié)合自己的語(yǔ)法書籍來(lái)適當(dāng)復(fù)習(xí)，這兒就不贅述，主要略列一些特殊用法，希望對(duì)各位英語(yǔ)愛好者有所幫助。
1． can和could
⑴Can 和 could 可以表示某人或某物一時(shí)的特點(diǎn)，可以翻譯為“有可能，有時(shí)會(huì)”。
It can be very warm in this area 。這個(gè)地區(qū)有時(shí)可能非常暖和.
He can be very friendly at times 。他有時(shí)會(huì)非常友好。
⑵can表示能力時(shí)（即有某種知識(shí)和技能而能辦到），可以與be able to 換用。但是在將來(lái)時(shí)和完成時(shí)中
必須用be able to ；表示經(jīng)過(guò)努力而成功地辦到了某個(gè)具體的事情時(shí)，只能用be able to ，不可以用can。
這種用法的be able to 相當(dāng)于succeed in 或manage to。另外：can not 比 cannot 更強(qiáng)調(diào) 。
Can you type ？＝ Are you able to type ？
I am sure we shall be able to get you a jop 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 。（沒有能力爬，因而也沒有爬）
He was not able to climb the mountain 。（嘗試爬過(guò)，但是沒能爬上去）
另外：
①be able to 強(qiáng)調(diào)能力，通常表示一次性的事件，一般不表示經(jīng)常性的事件。
I was able to pass the examination 。（＝I succeeded in passing the examination 。）
我能考試及格。（考試及格了）
After studying that you will be able to sovle these mathematics problems 。
學(xué)習(xí)完這個(gè)方法后，你能夠解這些數(shù)學(xué)題了。
②在否定句結(jié)構(gòu)中，be able to 指暫時(shí)的情況，而can可以指經(jīng)常的情況。
He is not able to swim today 。他今天不能游泳。
He can't swim at all 。他根本不會(huì)游泳。
I shall not be able to go to school tomorrow 。我明天不能上學(xué)了。
③在表示“經(jīng)過(guò)嘗試或努力為能做到”的意思時(shí)，一般不用be able to。如對(duì)Were you able to
find the pen？做否定回答應(yīng)該用：No，I couldn't （find it ）。不能說(shuō)：No ，I wasn't able
to find it 。
④could 可以用來(lái)表示過(guò)去習(xí)慣性動(dòng)作的完成，而was able to 卻沒有這種用法。
I could run after a bus and catch it twenty years ago ，I can't do that now 。
二十年前，我能在后面跑著追上公共汽車，現(xiàn)在不行了。
⑤cannot ／can't 與too／over（‐)／enough ／perfectly ／sufficiently 等詞連用，意思是
“越…越…”“無(wú)論怎樣… …也不為過(guò)”、“決不會(huì)… …夠(過(guò))”。
You can't praise him too much 。你無(wú)論怎樣稱贊他都不過(guò)分。
You cannot be over careful 。你越細(xì)心越好。
I can't thank you enough 。我對(duì)你感激不盡。
This point cannot be overemphasized 。這一點(diǎn)無(wú)論如何強(qiáng)調(diào)都不過(guò)分 。
注釋：
⑴can't ／cannot …too ／enough 等中的not ，也可以用never ／hardly ／scarcely
等代替。
There can never be too much deception in war 。兵不厭詐。
We can hardly/scarecely pay too high a price for liberation .
為了解放，我們無(wú)論付出多高的代價(jià)也不為過(guò)。
⑵can't / cannot … …too / enough 等后的附加疑問(wèn)句的動(dòng)詞用肯定形式can，不用
can't。
You can't praise him too much ，can you ？你無(wú)論怎樣贊揚(yáng)他都不為過(guò)，對(duì)吧
You cannot be too careful ,can you ? 你再小心也不為過(guò)，對(duì)吧？
⑶“cannot wait 不定式 ”意思是“be eager to … … 急于做”，表示強(qiáng)調(diào)的肯定意思 。
I cannot wait to read the book 。我非?？释x這本書 。
He couldn ’t wait to see her 。他渴望見到她 。

2． must有一種含義：“偏要”“硬要”。表示說(shuō)話人對(duì)句子主語(yǔ)所發(fā)出的動(dòng)作或行為是不希望的、不滿的甚至是生氣的。通常指令人不愉快的事情。must用于第二人稱時(shí)，常常含有諷刺挖苦的意思：
Why must you be so stubborn （固執(zhí)）？
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 （煙灰缸）。00

另：⑴have to 多表示習(xí)慣動(dòng)作或客觀條件索引出的義務(wù)；而must則用于表示一種重要或急迫的事
情：
We have to care for the young 。（義務(wù)）
She has to be at the office before 8 every day 。（習(xí)慣）
You must go to the manager at once ，or you 'll be diamissed 。（急迫的事情）
⑵通常have to 強(qiáng)調(diào)客觀需求，表示因客觀環(huán)境或事態(tài)促使而不得不作某事；must 強(qiáng)調(diào)主觀看法，
表示主觀上認(rèn)為有必要做謀事。
I must learn another language 。（主觀想法：I want to ）
I have to learn another language 。（客觀需求：身為一個(gè)外交官）
但是must 可以表示客觀必然性，意思為“必然（會(huì)），總是會(huì)”，而have to 則不可以這樣用。
All men must die 。人固有一死。
Competition must happen 。競(jìng)爭(zhēng)總會(huì)發(fā)生。
Truth must be out 。真相總會(huì)大白 。
Winter must be followed by spring 。冬天到了，春天還會(huì)遠(yuǎn)嗎 ？
There must be a day for revenge 。總有報(bào)仇的那一天 。
⑶對(duì)must 所在句子變反意疑問(wèn)句時(shí)，應(yīng)注意以下習(xí)慣搭配：
①must 作“必須”解時(shí)，反意疑問(wèn)句中重復(fù)must 。
All the children must respect their parents ，mustn’t they ？
孩子必須尊敬父母，對(duì)嗎？
②must 作“有必要”解時(shí)，反意疑問(wèn)句中用need 。
We must tell her the truth ，needn’t we ？我們現(xiàn)在有必要告訴她實(shí)情，對(duì)嗎？
③“must be ”表示推測(cè)時(shí)，反意疑問(wèn)句用be 的適當(dāng)形式 。
You must be thirsty ，aren’t you ？你一定渴了，是嗎 ？
④“must have done ”表示推測(cè)時(shí) ，附加疑問(wèn)句一般用have 或 has ，但是有明確表示過(guò)去
的時(shí)間壯語(yǔ)（before 除外）時(shí)，反意疑問(wèn)句用過(guò)去時(shí)態(tài)。
He must have finished the work ，hasn ’t he ？
He must have gone abroad last week ，didn’t he ？
You must have been tould about it that day ，weren’t you ？
⑤mustn’t 表示“禁止，不允許”時(shí)，反意疑問(wèn)句一般用may 。

也可以用must 。

3.used to 的意思是“過(guò)去常常”，已經(jīng)含有 always ，often ，sometimes ，from time to time等意思，但是它卻可以和它們連用。
He always used to / used always to come by bus 。 他過(guò)去總是坐公共汽車來(lái)。
He often used to work late at night 。他過(guò)去經(jīng)常工作到深夜。
She always used to get up at four o'clock in the morning 。她過(guò)去總是早晨4點(diǎn)起床。
但是used to 不可以與表示具體次數(shù)或一段時(shí)間(即特定的時(shí)間段)的詞語(yǔ)連用。
He went to abroad three times 。
He lived in the countryside for three years 。
但是可以和過(guò)去確定的時(shí)間壯語(yǔ)連用。
He used to live here in 1995。
He used to be devoted to her when she was a little girl 。
In those days we used to live in the country 。
另：would 和used to 的區(qū)別如下：
兩者都可以表示過(guò)去的習(xí)慣性動(dòng)作。但是would 只強(qiáng)調(diào)過(guò)去特定情況下的習(xí)慣性動(dòng)作(由動(dòng)態(tài)動(dòng)詞表示)，單純的過(guò)去和現(xiàn)在無(wú)關(guān)；而used to 即可以強(qiáng)調(diào)過(guò)去的習(xí)慣性動(dòng)作(由動(dòng)態(tài)動(dòng)詞表示)，也可以強(qiáng)調(diào)過(guò)去的事實(shí)或狀態(tài)(由靜態(tài)東此表示)，且與現(xiàn)在形成對(duì)比，即可表示持續(xù)的狀態(tài)，也可表示過(guò)去重復(fù)的行為。

I didn't use to like opera ，but now I'm getting interested 。
我過(guò)去不喜歡歌劇，但現(xiàn)在逐漸有了興趣。
上面兩句話的動(dòng)詞均是靜態(tài)動(dòng)詞，說(shuō)明過(guò)去的事實(shí)或狀態(tài)，不能用would 代替used to 。
注：woud 和used to一樣，都不可用來(lái)表示發(fā)生的次數(shù)，也不能與表示一個(gè)特定的時(shí)間段的狀語(yǔ)連用。
He went to Lomdon three times when he was a child .他還是孩子時(shí)，去過(guò)倫敦三次。
但是would可以和sometimes/now and then/from time to time 等詞組（表示過(guò)去有時(shí)或偶爾的時(shí)間狀語(yǔ)）連用。

不能用will或would ,而要用一般現(xiàn)在時(shí)或一般過(guò)去時(shí)來(lái)代替。
