( No, Im afraid not. )3) 表示客观可能性（客观原因形成的能力）。Theyve changed the timetable, so we can go by bus instead.This hall can hold 500 people at least. 4) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。Can this be true?This cant be done by him.How can this be true?二must, have to1) 表示必须、必要。You must come in time.在回答引出的问句时，如果是否定的，不能用mustnt（禁止，不准），而用neednt, dont have to（不必）.- Must we hand in our exercise books today?- Yes, you must.- No, you dont have to / you neednt.2) must是说话人的主观看法， 而have to则强调客观需要。Must只有一般现在时， have to 有更多的时态形式。1 he play isnt interesting, I really must go now.2 I had to work when I was your age.3) 表示推测、可能性（只用于肯定的陈述句）1 Youre Toms good friend, so you must know what he likes best. Your mother must be waiting for you now.shall, should1) shall 用于第一人称，征求对方的意见。What shall we do this evening?2) shall 用于第二、三人称，表示说话人给对方的命令、警告、允诺或威胁。1. You shall fail if you dont work hard.(警告)2. He shall have the book when I finish it.(允诺)3. He shall be punished.(威胁)三will, would1) 表示请求、建议等，would更委婉。Will / Would you pass me the ball, please?2) 表示意志、愿望和决心。1. I will never do that again.2. They asked him if he would go abroad. 3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式，且没有“现已无此习惯”的含义。1. During the vacation, he would visit me every other day.2. The wound would not heal.4) 表示估计和猜想。 It would be about ten oclock when she left home.四、 dare, need1) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。1 How dare you say Im unfair?2 He darent speak English before such a crowd, dare he?3 If we dared not go there that day， we couldnt get the beautiful flowers.2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。1You neednt come so early.2. - Need I finish the work today? - Yes, you must. / No, you neednt.3) dare和 need作实义动词用时， 有人称、时态和数的变化。在肯定句中，dare后面常接带to的不定式。在疑问句和否定句中，dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。1.
