【正文】 ry when you go to the bookstore? Will you have some rice? 2). would(1)will的過去式,表示過去的意愿和決心。 We didn’t know that he might be our new teacher. The accident might happen the day before yesterday. (2)替代may來表示現(xiàn)在時間的動作,主要于推測(但其可能性比may更低)。 (1) 與原形相同的有: must must ought to ought to (2) 與原形不同的有: can could will would may might shall should need needed dare dared have to had to (二)情態(tài)動詞的種類:(見下表)原 形過去式詞 義cancould能maymight可以(或許)mustmust(had to)必須(不得不)willwould愿意shallshould應該needneeded需要daredared敢于(三)情態(tài)動詞的否定形式:cannot can’t could not couldn’t may not mayn’t might not mightn’t must not mustn’t will not won’t would not wouldn’t need not needn’t shall not shan’t should not shouldn’t ought not oughtn’t dare not daren’t (四)常用情態(tài)動詞的用法:1.can與could1). can(1)表示體力或腦力方面的“能力”,也能表示根據(jù)客觀條件能做某事的“能力”。 2.情態(tài)動詞本身有詞義,但詞義不完全,不能單獨用作謂語,沒有人稱和數(shù)的變化,且后面只跟動詞原形。 Could you go skating with me tomorrow? I’m afraid I couldn’t give you an answer tonight.(3)表示驚異、懷疑、不相信等態(tài)度 How could he say that? He couldn’t be in Beijing. 2.may與might1). may(1)表示請求、許可、可以 —May I use your dictionary? —Yes, please/certainly. May I e in?

Shall the doctor e?2). should(1)should意思是“應該”,表示勸告或建議(=ought to) You should wash your hands before dinner. We should help each other. (2)用來表示可能性或猜測。 8. dare1) dare意思是“敢”,用于肯定結(jié)構(gòu)中時,后接加to的動詞不定式。will, would, shall 的用法  ?。?) will 在一般疑問句中表示客氣的“請求、勸說”。 (2)當句子表推測時,用can’t 表達不可能, He can’t be ill. He is playing chess with Tom.(3)can’t 還可用來回答“ May I …? ” 這樣的問句。You needn’t meet him unless you’d like to. (2)needn’t + have+ 動詞的過去分詞,表不需要完成但已完成的動作,暗含時間或精力上的浪費。Jim can’t speak English. He could speak English at 5. We’ll be able to see him next week. He has been able to drive. I ‘m sure you ‘ll be able to finish it quickly. We were able to reach the top of the mountain at noon.易混點二can’t
