情態(tài)動(dòng)詞講解
一、情態(tài)動(dòng)詞的意義:情態(tài)動(dòng)詞表示說話人對(duì)所說動(dòng)作的觀點(diǎn)。如需要、可能、意愿、懷疑等。在形式上,情態(tài)動(dòng)詞一般沒有人稱和數(shù)的變化。有的情態(tài)動(dòng)詞沒有時(shí)態(tài)的變化。情態(tài)動(dòng)詞本身詞義不完全,不能單獨(dú)做謂語動(dòng)詞,必須和不帶to的動(dòng)詞原形連用。情態(tài)動(dòng)詞的否定式一般是在后邊加not構(gòu)成。一般疑問句通常將其提到句首。
二、情態(tài)動(dòng)詞的用法:
一)can, can’t
1.can表示能力。如:
We can speak a little English.
我們能說一點(diǎn)兒英語。
2. can表示許可。如:
You can play basketball on weekends.
周末你可以打籃球。
3. can表示請(qǐng)求。如:
Can you help me with my Chinese?
你能幫助我學(xué)漢語嗎?
4. can’t表示否定推測(cè)。如:
---Listen! Lee is playing the piano in the room.
聽!Lee正在房間里彈鋼琴。
---It can't be her. She has gone to Beijing.
這肯定不是她。她去了北京。
二)could
1. 表示過去的能力。如:
I could swim at the age of four.
我在四歲的時(shí)候能游泳。
2. 表示委婉的請(qǐng)求。如:
1)Could you please tell me how I can use the computer?
請(qǐng)你告訴我怎樣使用這臺(tái)電腦好嗎?
2)---Could you go with me? 你能和我一塊兒去嗎?
---Sorry, I can't.不好意思,我不能。
三)may
1. 表示許可,意思是可以。如:
---May I borrow your dictionary?
我能借你的字典嗎?
---Of course, you may/ can. 當(dāng)然,你可以。
2. 表示可能性。如:
It may be true. I'm not sure. 它可能是真的,我不確定。
四)must, mustn’t
1. must表示必須。一般有強(qiáng)制性,可用于表示規(guī)則。比如學(xué)校規(guī)則、家庭規(guī)則、交通規(guī)則、實(shí)驗(yàn)室規(guī)則、閱覽室規(guī)則等等。如:
1)You must finish your homework first.
你必須首先完成作業(yè)。
2)You must read a book before you watch TV.
在你看電視之前必須讀一本書。
2. must表示肯定推測(cè)。如:

這本書肯定是Lily的。她的名字在書上。
3.mustn’t表示不準(zhǔn);禁止。如:

五)need, needn’t
1. need需要。如:
I need your help.

2. needn’t不必。相當(dāng)于not have to。如:

六)should, shouldn’t
1.You should eat more vegetables.
你應(yīng)該多吃蔬菜。
2.You shouldn't eat too much food.
你不應(yīng)該吃的太多。
七)might可能。比may可能性更小。如:

明天可能晴天。
八)shall將要,多用于第一人稱,表示征求對(duì)方的意見。如:
Shall we go out for a walk?
我們可以出去散步嗎?
