  (1)表示“能力”。 Even a child can operate the computer,let alone an adult. (2)表示惊讶,常用在否定句和疑问句中。 How could you do such a silly thing? (3)表示可能。 It is usually warm in my hometown in March,but it can be rather cold sometimes. (4)cannot... too/enough表示“无论……也不过分”;“越……越好”。 I can’t thank you too much for all your help to my son while we were away from home.(2017·陕西高考)

  2.may和might的用法 (1)may和might表示“许可、可能性、祝愿”等意义。 ①在给予别人许可时,常用can,但有时也用may。不能用might。 —May I take the book out? —I’m afraid not. ②“may as well+动词原形”意为“最好;倒不如”。 We may as well stay where we are. (2)may作“可以”讲时,其否定式常用“mustn’t”表示“禁止”;must作“必须”讲时,其否定式是“needn’t”,表示“不必”。 —May I take this book out of the reading room? —No,you mustn’t. You read it in here.

  3.must的用法 (1)表示禁止(用于否定句)。 The new law states that people mustn’t drive after drinking alcohol.(2017·上海高考) (2)表示“偏执;固执”。 If you must go,at least wait until the storm is over.(2011·辽宁高考) 4.shall的用法 (1)用于第一、第三人称疑问句中,表示说话人征求对方的意见和向对方请示。 —What time shall I pick you up at your house tomorrow,sir? —I haven’t decided on the time.But I will call you. (2)用于第二、第三人称陈述句中,表示说话人给对方的命令、警告、允诺或威胁。 No driving electric motor bikes in some areas is a rule that you shall obey in Fuzhou. 5.will和would的用法 作情态动词的will,would与作助动词的will,would的各种形式相同。 (1)表示自愿做或主动提出做什么,如意志、愿望或决心等。would用于过去的情况。 —Goodbye,John. Come back again sometime. —Sure. I will.(2017·四川高考) —Why didn’t you come to Simon’s party last night? —I wanted to,but my mom simply would not let me out so late at night. (2)will可以表示一种习惯性的动作,有“总是”或“总要”之意。 Every morning he will have a walk along this river. (3)would可以表示过去的习惯性动作,比used to正式,但没有“现已无此习惯”的含义。 When we worked in the same firm several years ago,we would often go to the cinema together. 6.情态动词+have+过去分词 (1)can/could have done表示“本来可以做,而实际上未做”或者“过去可能”,疑问或否定形式表示对过去发生的行为表示怀疑或不肯定,其中can’t have done多用于语气强烈的否定,意为“不可能做过”。 —Do you know where David is?I couldn’t find him anywhere. —Well.He can’t have gone far—his coat’s still here. I could have saved the poor rabbit,but I didn’t have the right drugs with me at that moment. (2)may/might have done表示对过去行为的推测,意为“可能做过”。might所表示的可能性比较弱,语气较委婉。此外might have done可表示“本可能做而实际上未做”。 Sorry,I’m late.I might have turned off the alarm clock and gone back to sleep again. (3)must have done表示对过去行为的推测,意为“一定;想必”,语气十分肯定。 Jack described his father,who must have been a brave boy many years ago,as a strong­willed man. (4)should have done表示过去本来应该做某事而实际上却没有做;shouldn’t have done表示过去本来不应该做某事而实际上却做了。这一用法往往含有责备的意味。 I shouldn’t have watched that movie—it’ll give me horrible dreams. (5)ought to have done表示过去本来应该做某事而实际上却没有做;ought not to have done表示过去本来不应该做某事而实际上却做了。这一用法与should相同,也往往含有责备的意味。 You ought to have come to the party yesterday,but why didn’t you come? (6)needn’t have done表示本来不必做某事而实际上却做了。 Mark needn’t have hurried. After driving at top speed,he arrived half an hour early.

  二、虚拟语气

  1.非真实条件句中虚拟语气的用法 if条件从句 从句的谓语形式 主句的谓语形式 表示现在情况 动词过去式(be的过去式用were) should/would/could/might+动词原形 表示过去情况 had+过去分词 should/would/could/might+have+过去分词 表示未来情况 should+动词原形 should/would/could/might+动词原形 动词过去式 were to+动词原形 We would be back in the hotel now if you didn’t lose the map.(2017·北京高考) If it snowed/were to snow/should snow tomorrow,we would take photos. 【名师指津】 若条件句中有were,had,should,可把if省略,而把were,had,should放在主语前,形成倒装结构,这种结构主要用于书面语中。 Were there no modern telecommunications,we would have to wait for weeks to get news from around the world.(2017·福建高考) Should it rain tomorrow,we would have to cancel the football match. 2.错综时间虚拟条件句 If you had worked hard,you would be very tired now.(从句指过去,主句指现在) 3.含蓄虚拟语气 有时假设的情况并不用条件从句表达,而是由otherwise,but,or,without,but for等来引导。 I was so busy then,otherwise I would have gone to help him. I would have come sooner but I didn’t know that they were waiting for me.(2011·天津高考) 4.某些从句中虚拟语气的用法 (1)表示命令、建议、要求、愿望等含义的动词后宾语从句和同位语从句时用虚拟语气,形式为:(should+)动词原形。常这样用的动词有:advise劝告,demand要求,desire渴望,command命令,insist坚决要求,prefer宁愿,urge主张,order命令,recommend 劝告;建议,request要求,require要求,suggest建议,以及这些词的名词形式。 Teachers recommend parents not allow their children under 12 to ride bicycles to school for safety. (2)wish后跟宾语从句时用虚拟语气。 对现在情况的假设: wish+主语+动词过去式(be用were) 对过去情况的假设: wish+主语+had+过去分词 对将来情况的假设: wish+主语+would+动词原形 —How much of the foreign expert’s speech have you understood? —Next to nothing.
