9、 clothes,take on a mobile phone,以上我们已经通过归纳总结和练习对本课的语法内容有了一定的了解, 下面就让我们根据之前练习的考察情况进一步选择讲解该语法项的重难点。,语法讲解,1. can, could 表示能力(体力, 知识, 技能), 常用情态 动词can和could表达。 Can you lift this heavy box? (体力) Mary can speak three languages. (知识) Can you skate? (技能) 此时可用be able to代替。can只有一般 现在时和一般过去式; 而be able to 则有 更多的
10、时态。,如：Ill not be able to come this afternoon. (一般将来时) 当表示“经过努力才得以做成功某事”时用be able to, 不能用can。如： He was able to go to the party yesterday evening in spite of the heavy rain.,表示请求和允许。如： Can I go now? Yes, you can. / No, you cant. 此时可与may互换。在疑问句中还可用could, might代替，但could, might并不表示过去式，只是语气更委婉。它们不能用于肯定句和答
11、语中。如： Could I come to see you tomorrow? Yes, you can. (No, Im afraid not.),表示客观可能性(客观原因形成的能力)。 如： Theyve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least.,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
12、?,2. may, might 表示请求和允许。might比may语气更委婉，而不是过去式。否定回答时可用cant 或mustnt，表示“不可以，禁止”。如： Might / May I smoke in this room? No, you mustnt. May / Might I take this book out of the room? Yes, you can. (No, you cant /mustnt. ) 用May I .？征徇对方许可时比较正式和 客气，而用Can I .？在口语中更常见。,用于祈使句，表示祝愿。如： May you succeed! 表示推测、可能性 (
13、不用于疑问句)。 might不是过去式，它所表示的可能 性比may小。如： He may / might be very busy now. Your mother may / might not know the truth.,3. must, have to 表示命令、禁止、不得不。如： 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, yo
14、u dont have to / you neednt.,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。如： His play isnt interesting, I really must go now. I had to work when I was your age.,表示推测、可能性（只用于肯定的 陈述句)。如： Youre Toms good friend, so you must know what he likes best. Your mother must be waiting for you no
15、w.,4. shall, should shall 用于第一人称，征求对方的意见。 如：What shall we do this evening? 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。 You shall fail if you dont work hard. (警告) He shall have the book when I finish it. (允诺) He shall be punished. (威胁),5. will, would,表示请求、建议等，would更委婉。如: Will / Would you pass me the ball,
16、please? 表示意志、愿望和决心。 如: I will never do that again. They asked him if he would go abroad.,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。如： During the vacation, he would visit me every other day. The wound would not heal. 表示估计和猜想。例如： It would be about ten oclock when she left home.,shou
17、ld, ought to表示“应该”，ought to 表示义务或责任，比should语气重。 I should help her because she is in trouble. You ought to take care of the baby.,6. should, ought to,表示劝告、建议和命令。should, ought to可通用，但在疑问句中常用should。 You should / ought to go to class right away. Should I open the window?,表示推测 should/ ought to 客观推测 must
18、主观推测 He must be home by now. (断定他已到家) He ought to/should be home by now. (不太肯定) This is where the oil must be. (直爽) This is where the oil ought to/should be. (含蓄),情态动词练习,1. 你必须马上回家。 You must go home now. 2. 他一定吃过什么东西了。 He must have eaten something. 3. 吃饭之前不能吃零食。 You mustnt eat snacks before meals.,4
