48、有所幫助 祝樓主進步哈 一分類 情態(tài)動詞有四類： 只做情態(tài)動詞：must,can(could,may(might, 可做情態(tài)動詞又可做實義動詞：need,dare 可做情態(tài)動詞又可做助動詞：shall(should,will(would ,ought to 具有情態(tài)動詞特征：have(had,has to,used to 情態(tài)動詞表猜測 二位置 情態(tài)動詞有一定的詞義，但并不完整，必須與動詞原形一起構(gòu)成謂語。 I can see you. Come here. 我能看見你，過來吧。 He must have been away. 他一定走了。 What can I do for you? 我能幫

49、你嗎？ How dare you treat us like that！ 你怎能那樣對待我們！ 三特點 情態(tài)動詞無人稱和數(shù)的變化, 情態(tài)動詞后面跟的動詞需用原形,否定式構(gòu)成是在情態(tài)動詞后面加 "not"。 個別情態(tài)動詞有現(xiàn)在式和過去式兩種形式, 過去式用來表達更加客氣, 委婉的語氣, 時態(tài)性不強, 可用于過去，現(xiàn)在或?qū)?。情態(tài)動詞屬非及物動詞，故沒有被動語態(tài)。 He could be here soon. 他很快就來。 We can't carry the heavy box. 我們搬不動那箱子。 I'm sorry I can't help you

50、. 對不起，我?guī)筒簧夏恪?基本助動詞與情態(tài)助動詞最主要的區(qū)別之一是，基本助動詞本身沒有詞義，而情態(tài)助動詞則有自己的詞義，能表示說話人對有關(guān)動作或狀態(tài)的看法，或表示主觀設(shè)想： What have you been doing since? （構(gòu)成完成進行體，本身無詞義） I am afraid I must be going. （一定要） You may have read some account of the matter. （或許已經(jīng)） 除此之外，情態(tài)助動詞還有如下詞法和句法特征： 1） 除ought和used以外，其他情態(tài)動詞后面只能接不帶to的不定式。如果我們把ought to和use

51、d to看做是固定詞組的話，那么，所有情態(tài)動詞無一例外地只能接不帶to的不定式： We used to grow beautiful roses. I asked if he would come and repair my television set. 2） 情態(tài)助動詞在限定動詞詞組總是位居第一： They need not have been punished so severely. 3） 情態(tài)助動詞用于第三人稱單數(shù)現(xiàn)在時的時候，沒有詞形變化，即其詞尾無-s形式： She dare not say what she thinks. 4） 情態(tài)動詞沒有非限定形式，即沒有不定式和分詞形式，

52、也沒有相應的動名詞： Still, she needn't have run away. 5） 情態(tài)助動詞的“時”的形式并不是時間區(qū)別的主要標志。在不少場合，情態(tài)助動詞的現(xiàn)在時和過去時形式都可以表 示現(xiàn)在、過去或?qū)頃r間： Would you mind very much if I ask you to do something? She told him he ought not to have done it. 6） 情態(tài)助動詞之間是相互排斥的，即在一個限定動詞詞組中只能出現(xiàn)一個情態(tài)助動詞，但有時卻可以與have和be基本助動詞連用： You should have washed

53、the wound. Well, you shouldn't be reading a novel. 四用法 首先它是動詞，而且不同于行為動詞，行為動詞表示的是可以通過行為來表達的動作（如寫，讀，跑），而情態(tài)動詞只是表達的一種想法（如能，也許，敢）。 用法是：情態(tài)動詞+行為動詞原形 例句：I can read this sentence in English. 我能用英語讀這句話。 情態(tài)動詞是一種本身有一定的詞義,表示說話人的情緒,態(tài)度或語氣的動詞,但不能單獨作謂語, 只能和其他動詞原形構(gòu)成謂語。 We can be there on time tomorrow.我們明天能按時去那兒。

54、 May I have your name? 我能知道你的名字嗎？ Shall we begin now?我們現(xiàn)在就開始嗎？ You must obey the school rules.你必須遵守校規(guī)。 情態(tài)動詞數(shù)量不多,但用途廣泛,主要有下列: can (could, may (might, must, need, ought to, dare (dared, shall (should, will (would,have (to ,had better. 情態(tài)動詞還有一個很重要的用法，即情態(tài)動詞表推測 情態(tài)動詞表推測的用法小結(jié) （一）情態(tài)動詞表推測的三種句式 1.在肯定句中一般用must

55、 (一定，may（可能），might / could（也許，或許）。 （1）He must/may/might know the answer to this question? 他一定/可能/也許知道這個問題的答案。 （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。 （1）It cant/couldnt be the headmaster. He has gone to Ameri

56、ca. 這不可能是校長，他去美國了。 （2）He may not/might not know the scientist. 他也許不認識那位科學家。 3.疑問句中用can/could (能?。 （1）Could he have finished the task? 他可能把任務完成了嗎？ （2）Can he be at home now? 他現(xiàn)在能在家嗎？ 注：以上三種句式中情態(tài)動詞的語氣按程度都是依次遞減的。Might, could并非may, can的過去式，而表示語氣較為委婉或可能性較小。 （二）情態(tài)動詞表推測的三種時態(tài) 1.對將來情況的推測，用“情態(tài)動詞 + 動詞原形”。 （1）Sh

57、e must / may / might / could arrive before 5. 5:00前她一定/可能/也許到。 （2）She must/may/might/could walk miles and miles among the hills without meeting anyone. 她一定/可能/也許會在山里一連走好幾英里而遇不到一個人。 2.對現(xiàn)在或一般情況的推測，用“情態(tài)動詞 + be” ，“情態(tài)動詞 +be doing”或“情態(tài)動詞 + 動詞原形”。 （1）He must / may / might / could be listening to the radio

58、now. 他一定/可能/也許正在聽收音機。 （2）He cant ( couldnt / may ( might not be at home at this time. 這個時候他不可能/可能不在家。 （3）Mr. Bush is on time for everything .How can ( could he be late for the opening ceremony ? 布什先生一向準時，這次開幕式他怎么可能遲到呢？ 3.對過去情況的推測，用“情態(tài)動詞 + have +過去分詞”。 （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 not / may ( might not have
