初中英語(yǔ)情態(tài)動(dòng)詞專項(xiàng)練習(xí)題集

1、情態(tài)動(dòng)詞情態(tài)動(dòng)詞是一種本身有一定的詞義，但要與動(dòng)詞原形及其被動(dòng)語(yǔ)態(tài)一起使用，給謂語(yǔ)動(dòng)詞增添情態(tài)色彩，表示說話人對(duì)有關(guān)行為或事物的態(tài)度和看法，認(rèn)為其可能、應(yīng)該或必要等。情態(tài)動(dòng)詞后面加動(dòng)詞原形。情態(tài)動(dòng)詞有四類：只做情態(tài)動(dòng)詞：must,can(could),may(might)可做情態(tài)動(dòng)詞又可做實(shí)義動(dòng)詞：need，will具有情態(tài)動(dòng)詞特征：have(had,has) to,used to，ought to情態(tài)動(dòng)詞表猜測(cè)：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。）注：mustnt代表強(qiáng)烈禁止 must表示主觀，have to表示客觀。常用的有：canm

2、aycouldmust haveuse.情態(tài)動(dòng)詞無人稱和數(shù)的變化，情態(tài)動(dòng)詞后面跟的動(dòng)詞須用原形，否定式構(gòu)成是在情態(tài)動(dòng)詞后面加 not。個(gè)別情態(tài)動(dòng)詞有現(xiàn)在式和過去式兩種形式，過去式用來表達(dá)更加客氣，委婉的語(yǔ)氣，時(shí)態(tài)性不強(qiáng)，可用于過去，現(xiàn)在或?qū)怼Ｇ閼B(tài)動(dòng)詞屬非及物動(dòng)詞，故沒有被動(dòng)語(yǔ)態(tài)。情態(tài)動(dòng)詞表推測(cè)的用法小結(jié)（一）情態(tài)動(dòng)詞表推測(cè)的三種句式1在肯定句中一般用must （一定），can,could（可能），might /may（也許，或許）。e.g:(1)He must/can/may,might know the answer to this question.他一定/可能/也許知道這個(gè)問題的答案。

3、(2)It is cold in the room. They must have turned off the heating.屋里很冷，他們肯定把暖氣關(guān)了。2否定句中用cant / couldnt（不可能），may not/might not（可能不）。e.g:(1)It cant/couldnt be the headmaster. He has gone to America.這不可能是校長(zhǎng)，他去美國(guó)了。(2)He may not/might not know the scientist.他也許不認(rèn)識(shí)那位科學(xué)家。3疑問句中用can/could （能?）。e.g:(1)Could he

4、have finished the task?他可能把任務(wù)完成了嗎？注：以上三種句式中情態(tài)動(dòng)詞的語(yǔ)氣按程度都是依次遞減的。Might,could并非may,can的過去式，而表示語(yǔ)氣較為委婉或可能性較小。（二）情態(tài)動(dòng)詞表推測(cè)的三種時(shí)態(tài)1對(duì)將來情況的推測(cè)，用“情態(tài)動(dòng)詞 + 動(dòng)詞原形”。e.g:(1)She must / may / might / could arrive before 5.5:00前她一定/可能/也許到。2對(duì)現(xiàn)在或一般情況的推測(cè)，用“情態(tài)動(dòng)詞 + be”，“情態(tài)動(dòng)詞 +be doing”或“情態(tài)動(dòng)詞 + 動(dòng)詞原形”。e.g:(1)He must / may / might /

5、could be listening to the radio now.他一定/可能/也許正在聽收音機(jī)。(2)He cant ( couldnt ) / may ( might ) not be at home at this time.這個(gè)時(shí)候他不可能/可能不在家。3對(duì)過去情況的推測(cè)，用“情態(tài)動(dòng)詞 + have +過去分詞”。e.g:(1)It must / may / might / could have rained last night .The ground is wet.地濕了，昨晚肯定/可能/也許下雨了。(2)The door was locked. He can ( could

6、 ) not / may ( might ) not have been at home .門鎖著，他不可能/可能不在家。注：情態(tài)動(dòng)詞 should /ought to表推測(cè)時(shí)，意為“想必會(huì)，理應(yīng)”但與“have +過去分詞”連用時(shí)，則又可構(gòu)成虛擬語(yǔ)氣意為“本應(yīng)該做某事卻沒做”。例如：(4)Its seven oclock. Jack should/ought to be here at any moment.現(xiàn)在七點(diǎn)鐘了，杰克理應(yīng)隨時(shí)到達(dá)。（推測(cè)）（5）Tom should not /ought not to have told me your secret,but he meant no

7、harm. （虛擬）湯姆本不該告訴我你的秘密，可是他并無惡意。can 和could 表示推測(cè)的用法對(duì)現(xiàn)在或?qū)淼耐茰y(cè)，兩者均可用，但can 通常只用于否定句或疑問句中，一般不用于肯定句，而could則可用于肯定句、否定句和疑問句；對(duì)過去的推測(cè)，應(yīng)在 can,could 之后接動(dòng)詞的完成式，且此時(shí)can仍只用于否定句或疑問句，不用于肯定句；而could 則可用于各種句型。如：Can Could this be true? 這能是真的嗎Where can could he have gone? 他能到哪里去了呢She cant couldnt have left so soon. 她不可能走得這么

8、早。注：could后接動(dòng)詞的完成式，除表示對(duì)過去的推測(cè)外，還可表示過去沒有實(shí)現(xiàn)的可能性（即某事本來可以發(fā)生，卻沒發(fā)生），或委婉地責(zé)備某人過去應(yīng)該做某事而沒有去做（此時(shí)不用can）。如：You could have started a little earlier. 你本可早點(diǎn)動(dòng)身的。You neednt have cooked it. We could have eaten it raw. 你其實(shí)可以不煮熟（它），我們（本來）可以生吃。can 和could 表示允許的用法表示現(xiàn)在的允許時(shí)，若是請(qǐng)求別人允許自己做某事，兩者均可用，但用could 語(yǔ)氣更委婉；若是自己允許別人做某事，一般只用 ca

9、n，而不用 could。如：Can Could I come in? 我可以進(jìn)來嗎“Could Can I use your pen? ” “Yes,of course you can.” “我可以借用你的鋼筆嗎?”“當(dāng)然可以?！保ú荒苷fYes,you could.)表示過去的允許時(shí)，若表示過去一般性允許（即表示某人隨時(shí)都可以做某事），用could；若表示在過去某一特定情況下允許進(jìn)行某一特定的活動(dòng)，則不用 could。如：When I lived at home,I could watch TV whenever I wanted to. 我住在家里時(shí)，想什么時(shí)候看電影就可以什么時(shí)候看。（一般

10、性允許）I was allowed to see the film yesterday evening. 昨天晚上允許我去看了電影。（特定的允許，不能用 could)can 和could 表示能力的用法can 表示現(xiàn)在的能力，could 表示過去的能力，要表示將來具備的能力通常 be able to 的將來時(shí)態(tài)。其中要注意的是，could 表示過去的能力，通常只用于表示過去一般性能力，而不表示過去具體某次特定情形下能夠做某事的能力。如：他學(xué)習(xí)很努力，所以考試能及格。誤：He studied hard and could pass the exam.正：He studied hard and w

11、as able to pass the exam.注：若在否定句中沒有以上限制，即couldnt 可表示過去特定情況下的能力，如可說 He studied hard but still couldnt pass the exam.口訣：情態(tài)動(dòng)詞兩特點(diǎn)動(dòng)詞原形接后面，說話語(yǔ)氣較委婉。can 能力may許可，must責(zé)任或義務(wù)。否定回答neednt換，需要need, dare敢。should應(yīng)該，would愿，have to被迫表客觀。情態(tài)動(dòng)詞專項(xiàng)練習(xí)題1. - Where is Mary? - She _ in the library.
