They will be waiting .,快點，他們一定在等我們。,He will have got home by now.,他該到家了。,推測程度由高到低為,mustwillwouldought toshouldcancouldmaymight,will /would,表意愿，用于第一人稱。,w,ill,指將來，,would,用于間接引語指過去的將來,I wont argue with you .,I said I would do anything for him .,will /would,用于非人稱主語，表示固有的性質傾向，通常用于否定句。,The window wont open.,窗戶打不開。,The door wont shut.,門關不上,will/ would,表拒絕用于否定句即,wont,I wont marry a man I dont love.,I wont listen to your nonsenses .,would,用于虛擬語氣,I wish the rain would stop for a moment.,You would answer much better if you were more attentive.,注意：比較would與used to,二者均可表示習慣,不同之處在于，used to有現(xiàn)在已無此習慣的意思，并可表示一次性動作。,I dont swim so often as I used to.,我不像過去那樣常游泳了。,shall的用法,Shall除在一般將來時中用于第一人稱外，還有以下用法：,表義務，用于第二三人稱。如：,You shall do as you see me do. 你照我做的樣子做。,He shall be punished if he breaks the rule.,如果他不服從就要受到處罰。,4.shall與should,a.,在當代英語中，shall多用于正式法律文字。,如：,This law shall have effect in Scotland.,這部法律將 影響蘇格蘭。,b.表許諾，用于第二三人稱的肯定句和否定句。,如：,1.,you shall have my answer tomorrow? 你明天可以得到我的答復。,2.,she shall get her share. 我可以得到她的一份。,c.表征詢意見，用于第一三人稱的疑問句。,如：,1.,What shall he do next? 下一步他要干什么呢？,2.,Lets start tomorrow, shall we? 我們明天動身，好嗎？,I'm sorry that you should think so badly of me.,你竟把我想得這樣壞，我感到遺憾。,Three weeks should suffice.,三個星期可能足夠了。,7.,用于虛擬語氣,表推測，暗含很大的可能。如,:,I suggest that you should stay here as if nothing had happened.,我建議你待在這兒，就好像什么事也沒有發(fā)生。,must,的用法,1. must,表義務，后跟不定式一般式，可用于肯定句和疑問句。如：,Children must form a good habit in their everyday life.,兒童必須在他們的日常生活中養(yǎng)成良好的習慣。,Must he do it himself?,他必須親自做那件事嗎？,2. must,的否定形式表不許，后跟不定式一般式。如,:,Journalists must not make mistakes in their newspaper reports.,記者不允許在新聞報道中出錯。,3. must,表推測，暗含很大的可能，只用于肯定句。如：,（,1,）,I dont understand what they are saying. They must be foreign.,我聽不懂他們在說什么。他們一定是外國來的。,（,2,）,Lets have something to eat. You must be starving.,我們吃些東西吧。你一定餓了。,need,的用法,用作情態(tài)助動詞時，它只有一種形式，沒有人稱和數(shù)的變化，后跟不帶,to,的不定式，主要用于否定句和疑問句。否定式為,neednt.,助動詞dare,實義動詞dare,否定式,dare not,don,t(doesn,t,didn,t)dare,過去式,Dare/ dared?,dared,used to,的用法,1.,情態(tài)動詞,used to,只有一種形式，它后跟不定式一般式，可以表過去存在的習慣或狀態(tài)。如：,(1) In the past, people used to offer friends cigarettes when they met.,過去，人們見面時經常給朋友遞煙。,(2) Nowadays he gives fewer concerts than he used to.,如今他舉辦音樂會比從前少了。,2. used to,的否定結構卻有兩種形式。如：,(1) He used not to /usednt to smoke.,他過去不吸煙。,(2) He didnt use to smoke.,他過去不吸煙。,3. used to,的疑問結構常用,do,的形式。如：,(1) Did he use to smoke?,他過去吸煙嗎？,(2) He used to smoke, didnt he?,他過去吸煙，對嗎？,be used to,結構和情態(tài)動詞,used to,的區(qū)別：,1.,在,be used to,結構中，,be,是連系動詞，,used,是形容詞，,to,是介詞，因此只后跟名詞短語或動名詞。如：,Heavy smokers cannot stop smoking because they are used to nicotine.,吸煙多的人不能不吸煙，因為他們對尼古丁已經上癮了。,情態(tài)動詞,used to,前面沒有,be,，后跟不帶,to,的動詞不定式。如：,I used to get along very well with my cousin and we used to be very good friends.,我過去同我的表弟相處得很好，我們曾經是好朋友。,注意：,半助動詞,半助動詞后的主動詞用不帶,to,的不定式?？梢允且话阈问揭部梢允沁M行體或完成體。,(1)Why are you driving so fast in this area?you are supposed to know the speed limit.,(2)Mother is still not quiet well.
