(In fact you didn't go over your lessons.) 你们应把功课复习好的。（可事实上你们没有。）   You shouldn't have watched TV last night. (In fact you watched TV last night.) 你们昨天晚上本不该看电视。（可你们看了。）   You oughtn't to have entered the teachers' office without permission. 没有经过允许，你们本不该进老师的办公室   You oughtn't to have gone to the deserted place alone.  你不该独自去那荒凉之地。‎ ‎2．表示期待或推测。   If the flight was on time, you should/ ought to have arrived in Shanghai early this morning. 如果航班准点的话，你今早就能到上海了。  F．would have done表示与过去事实相反的假设或结果   I would have been happy to see him, but I didn't have time. 我会很高兴和他见面的，但我没时间见他。   If your father had still been alive, he would have felt very proud of you. 你父亲如果还健在的话，他会为你骄傲的。‎ 注意点 ‎1.表示能力，意为“能，会”，用can, could, be able to均可，could是can的过去式。区别是：can只有过去时could，而be able to有多种时态。‎ John can speak three foreign languages fluently.约翰能流利地说三门外语。‎ John could swim when he was four.约翰四岁时就会游泳。‎ I regretted that I hadn’t been able to drive him home.我后悔我没能开车送他回家。‎ Will you be able to help me learn English tomorrow?明天你能帮助我学习英语吗？‎ ‎2.表示请求或允许，意为“可以”时，用can、could或may均可，只不过can比may更正式，could比can语气更委婉。‎ Can I park my car in front of your office?我能把我的车停在你的办公室前面吗？‎ ‎----Could I use your bike now?----Certainly. Go ahead.‎ May I have a look at the photos that you took yesterday?我能看一下你昨天拍的照片吗？‎ ‎3. must, can, may/might表推测时的用法。‎ 表推测时must用于肯定句，can用于疑问句和否定句，may/might用于肯定句和否定句。must用于否定句时不表推测，表示“禁止，千万不做…”。‎ The man standing over there must be a doctor.站在那边的那个男子一定是个医生。‎ The man standing over there can’t be a doctor.站在那边的那个男子不可能是个医生。‎ can和may表推测都可用于否定句，但can’t的意思是“不可能”，may not的意思是“可能不”。可见can’t的否定意味更强。‎ A teacher like her may not be popular with the students.‎ 像她这样的老师可能不会受到学生的欢迎。‎ A teacher like her can not be popular with the students.‎ 像她这样的老师不可能会受到学生的欢迎。‎ ‎4. shall是近几年全国各省市高考中考查频率较高的一个重点情态助动词。主要掌握以下内容：shall与第一人称搭配，用于疑问句，表提出请求或征求意见；与二、三人称搭配，用于陈述句（肯定句和否定句），表警告、威胁、允诺、命令、强制、决心等。‎ Shall he open the window?他打开窗户好吗？（征求意见）‎ You shall get the justice that you want.你会得到你想要的公平。（表允诺）‎ You shall not use my camera if you don’t use it properly.如果你不正确使用，我不会让你使用我的照相机（表警告）‎ No, he shan’t go.不! 他不能去。（表命令）‎ Nothing shall stop us from carrying out this plan.什么也阻挡不了我们实施这项计划。（表决心）‎ ‎5. must和should推测之外的用法。‎ 上面讲了must在肯定句中表推测的用法，must在肯定句中还有“必须”的用法。注意二者不要混淆。另外，must还有“偏偏，非要做…”的意思。‎ We must do everything step by step.我们一定要一步一个脚印地做每一件事情。‎ If you must smoke, please go outside.如果你非要抽烟，请出去。‎ When everybody was in bed, he must turned the radio on.大家都上床睡觉了，他偏偏把收音机打开了。‎ should表示吃惊、赞叹、不满等情绪，是高考热点。‎ It’s wonderful that you should have achieved so much in these years.这几年你们有了这么大的成就真了不起。‎ You can’t imagine a gentleman like him should treat a lady so rudely.你想象不出来象他这样一位绅士竟然会如此粗鲁地对待一位女士。 ‎ 情态动词的反义疑问句 ‎1．当陈述句部分有情态动词must时 ‎（1）must表示“必须、禁止“时，反意疑问部分要用must (mustn’t) 。 You mustn’t stop your car here, must you?‎ ‎（2）must表示“有必要”时，反意疑问句部分要用needn’t。 ‎ They must finish the work today, needn’t they? ‎ You must see the doctor, needn’t you?‎ ‎（3）当must用来表示对现在的情况进行“推测”时，反意疑问部分要根据must后面的动词采用相应的形式。 ‎ He must be good at maths, isn’t he? ‎ （4） 当must用来表示对过去的情况进行“推测”（must + have done）时：‎ a). 单纯表示对过去的推测, 与现在无关, 反意疑问句附加部分用过去式。‎ b). 表示对过去的推测且影响到现在或持续现在, 反意疑问句附加部分用现在完成式。 ‎ She must have read the novel last week, didn’t she?‎ You must have told her about it, haven’t you?‎ She must have had a very good time, didn’t she?‎ He must have lived here at least ten years, hasn’t he?‎ ‎2.当陈述部分含有情态动词used to时，疑问部分可用usedn’t或didn’t　　‎ The old man used to smoke, didn’t he?或usedn’t he? ‎ ‎3. 当陈述部分带有情态动词ought to时，疑问部分用oughtn’t或shouldn’t We ought to read this book, oughtn’t we?或shouldn’t we?‎ ‎4.当陈述部分含有had better时，疑问部分用had 　You’d better finish your homework now, hadn’t you?‎ ‎5.陈述部分有have to +v.
