She can be ill at any times.在否定句中只能用can和may。所以can’t时用以代替mustn’t，语气比may更肯定。中文可以翻译为不可能。Michael______be a policeman, for he’s much too short.A.needn’t     B.can’t       C.should      D.may在疑问句只能用can，不能用may和must。He may be very busy now.       Can he be very busy now?He must be very busy now.       Can he be very busy now?needneed作为情态动词只有一种形式，只用于否定句和疑问句。 daredare作为情态动词用时有两种形式：dare和dared两个词形，除了可以用于否定句和疑问句外，还可以用于条件从句或表示怀疑的句子中。If he dare come,I will kick him out.  I don’t know whether hedare say.注意:He doesn’t dare(to)answer the question.（否定句）Does she dare(to)enter the dark room?（疑问句）shall用于第一人称：征求对方的意见。What shall we do this evening?用于第二、三人称：警告、命令、允诺、威胁等。You shall fail if you don’t work harder. 警告He shall have the book when I finish reading.允诺He shall be punished.威胁should劝告、建议、命令、应该做、道义上的责任。You should(ought to) go to class right away.   I should(ought to) help him because he is in trouble.will/would请求、建议，would比will委婉客气。Would you pass me the book?表示意志、愿望和决心。I will never do that again.    They asked us if we would do that againwould可表示过去反复发生的动作或某种倾向。During the vacation he would visit me every weekThe wound would not heal.（伤口老是不能愈合）would表示估计或猜想。It would be about ten when he left home.    What would she be doing there?情态动词+have done的用法could+have done：本可以做而实际上未能做。You could have done better, but you didn’t try your best.cannot+ have done：表示对现在或过去行为的否定推测。He cannot have been to that town.can+主语+ have done：表示对过去行为的怀疑或不肯定（用在疑问句中）。Can he have got the book?might(may)+ have done：对过去发生的行为不太肯定的推测。He may not have finished the work.If we had taken the other road, we might have arrived earlier.must+ have done：对过去发生的行为肯定的推测。其否定式为：cannot have done。You must have seen the film.You cannot have seen the film.needn’t+ have done：本来不必要做的而实际上又做了。You needn’t have watered the flowers,for it is going to rain.注意：didn’t need to(have to)do：没有必要做而实际上也没有做I didn’t need to clean the windows.My sister did it 2 hours ago.should(ought to)+ have done：本来应该做而实际上又没有做。其否定形式表示某中行为不该发生却发生了。You should have started earlier, but you didn’t.She shouldn’t have taken away my measuring tape,for I worked to use it.注意：He should have finished the work by now.（表推测）III.虚拟语气类   别用   法例   句If引导的条件从句与现在事实相反从句动词：过去式（be用were）主句动词：should/would/could/might+doIf he were here, he would help us.与过去事实相反从句动词：had+done主句动词：should/would/could/might+have+doneIf I had been free,I would have visited you.与将来事实相反从句动词：过去式/should+动词原形/were+to do主句动词：should/would/could/might+动词原形If it should rain tomorrow, we would not go camping.省略if的虚拟条件句将虚拟条件从句中的were，had,should放到主语之前，构成主谓倒装①Should he come ,tell him to ring me up.②Were I you,I would not do it.③Had I been free,I would have visited you.混合虚拟条件句不同时间的虚拟：各遵守各的规则①If he had listened to me, he would not be in trouble now.②If he had told me yesterday,I should know what to do now.③If I were you, I would have gone to her birthday party.虚拟与陈述的混合：各遵守各的规则①He could have passed the exam,but he wasn’t careful enough. ②You should have come earlier.The bus left a moment ago.含蓄虚拟条件句but for+名词表示虚拟条件句子或主句中的谓语动词的形式视具体情况而定。这是考查考生应变能力的最佳试题。---But for your timely warning,we ______ into great trouble.---You know we’re friends.A. would get          B. must have got    C. would have got      D. can’t have gotwithout+名词表示虚拟条件Without the air to hold some of the sun's heat, the earth at night would be freezing cold.动词不定式表示虚拟条件It would be only partly right to follow in this way.
