初中英語情態(tài)動詞總結(jié)及練習(xí)題新

1、仁愛英語情態(tài)動詞講解與練習(xí)I 情態(tài)動詞的定義    情態(tài)動詞表示說話人對某一動作或狀態(tài)的態(tài)度。II 情態(tài)動詞的特點  1）有一定詞義；2）不隨主語人稱和數(shù)的變化而變化；3）與動詞原形一起構(gòu)成謂語。III 情態(tài)動詞的基本用法can (could)1) 表示能力（會、能），could主要指過去時間。Can you sing this English song?Mary can tell many stories.Can you skate?I could swim when I was eight years old.2）表示請求和允許。

2、Can you bring some water for me? 你能帶給我一些水嗎？ -Can I go to play soccer now? 我能去踢足球嗎？- Yes, you can. / No, you cant. 是的，你能。/不，你不能。此時可與may互換。在疑問句中還可用could代替，不是過去式，只是語氣更委婉，不能用于肯定句和答語中。 1. Could you please turn down the music? 2. Could I have a rest?3）cant 表示推測的“肯定不，一定不”The boy cant be Li Ming. He is

3、 taller 那個男孩肯定不是李明，他比Jim高多了。may /might1) 表示請求和允許。否定回答時可用cant 或mustnt，表示“不可以，禁止”。 -May I smoke in this room? - No, you mustnt. - May I say it in Chinese? - Yes, you can. (No, you cant / mustnt.) 用May I.？(正式和客氣)，而Can I.？(口語常見) 在回答以may引起的問句時，往往不用Yes, may.或No, may not，而改用其他方法，肯定回答常用:Yes, please. / Certa

4、inly. /Sure. / Of course.等否定回答常用 Please dont./ Youd better not. / No, you mustnt/cant.等，以免顯得太嚴(yán)峻或不客氣。2) 表示推測、可能性（不用于疑問句）。 He may be at home.   他可能在家。 He may be very busy now. Her mother may not know the boymust1）表示義務(wù)。意為“必須”（主觀意志）、必要。We must study hard. 我們必須努力學(xué)習(xí)。You mustnt talk to her like t

5、hat.   你不能那樣對她說話。You must come in time. 在回答引出的問句時，肯定回答常用must，而如果是否定的，*不能用mustnt（禁止，不準(zhǔn)），而用neednt或dont have to（不必）. - Must we hand in our exercise books today? - Yes, you must. - No, you dont have to / you neednt. 2) 表示推測、可能性（只用于肯定的陳述句）意為“想必、準(zhǔn)是、一定”等，只用于肯定句。Youre his friend, so you must know

6、where he lives. Your mother must be waiting for you now.Shall 表征詢意見，用于第一人稱疑問句。Shall I get you some tea?   我給你點茶好嗎？What shall we do this evening?   我們今晚做什么？should表義務(wù)。意為“應(yīng)該”（某件事宜于做），用于各種人稱。You should be polite to your teachers.   你應(yīng)對老師有禮貌。You shouldnt waste any time. 

7、;  你不應(yīng)該浪費時間。will/would1）表意愿，用于各種人稱陳述句。I will look after your sister when you leave.   我愿在你離開時照顧你的妹妹。2）表請求，用于疑問句。Will you close the window? Its a bit cold.   請你把窗戶關(guān)上好嗎？有點冷。Wont you drink some more coffee?   再來一點咖啡好嗎？表委婉地提出請求、建議或看法等，would比will更委婉。 Would you like some

8、 chocolate?  來些巧克力好嗎？Would you mind cleaning the window?   請把窗戶擦一下好嗎？had betterhad better表示"最好"。相當(dāng)于一個助動詞，它只有一種形式，它后面要跟動詞原形。結(jié)構(gòu)為：had better do sth.The library is far from here. Youd better take a bus.如果要表達“最好不”時，常用had better not do sth.Its raining outside.

9、Wed better not go to the museum.含有had better的句子，在改為一般疑問句時，只需要將had置于句首即可。-Had I better leave here at once?need  既可做實義動詞用，又可做情態(tài)動詞用。作為情態(tài)動詞，只能用于疑問句和否定句。 need 作實義動詞時后面的不定式必須帶to。 1)  實義動詞： need（需要, 要求） need + n. / to do sth. I need some help. 我需要

10、一些幫助。He needs to do more exercise. 他需要做更多的練習(xí)。2) 情態(tài)動詞： need，只用原形need后加do，否定形式為need not。 Need I turn off the TV?  Yes, you must. / No, you needn't.注意：need構(gòu)成的疑問句，肯定回答用must.have to have to 意為“不得不”，后跟動詞原形，表示由于客觀因素，自己不想做但又不得不做某事。have to 有時態(tài)及人稱的變化。

11、I have to wash my clothes this weekend.She has to stay in bed and have a good rest.They had to walk home because there was something wrong with the car.在進行句型轉(zhuǎn)換時，需要借助于助動詞。have to à do / has to à does / had to à did(三)辨異 must和 have tomust表示主觀意志，而have to表示由于客觀因素不得不做某事。must沒有過去式, have to

12、有人稱和時態(tài)的變化。I told him that he must give up smoking.  我叫她必須戒煙。We had to get everything ready that night.  我們那晚得把一切準(zhǔn)備就緒。強化練習(xí)( ) 1 John_ come to see us this evening, but he isn't very sure yet(還). A. may B. can C. has to D. must( ) 3 -May I take this book out? -No, you_.A. can
