情态动词及答案.doc

情态动词强化训练一.情态动词用法一 can的用法 1.表示能力,有能、会、能够的意思。例如: Can you drive a car? 2.表示可能,常用于否定句或疑问句。例如: Can it be true? Today is Sunday. He cant be at school today. 3.表示允许,口语中代替may,有可以的意思。例如: You can use my car. 用于句式和人称:用于肯定句和否定句，也可以用于疑问句。一般用于第一，二人称。cannot 表示“禁止”。You can not smoke in the bus. 公共汽车上不许吸烟。Can I carry your bag? 我来替你提包好吗？Could I give you dinner one of these days? 这几天我请你吃顿饭行吗？Cant you do it tomorrow? 你不能明天做吗？回答形式:肯定回答，一般是yes, please. thanks。肯定回答，不能用could Could I use your phone?Yes, of course you can.“我可以用你一下电话吗？”“当然可以。”注意: 1 )要注意，在请求允许的用法中，could 并不是过去时，它指的都是将来时。2)一般不用过去一次性允许。During the meeting I could ask questions. (误)4.can和be able to 的区别: can表示能力时,可以用be able to代替;can只有can和could两种时态,而be able to可用于其他时态;be able to强调通过努力有能力做到,如果表示某事已经成功应用 be able to,而不用could。例如: He was able to leave Europe before the war began. 二、may的用法 意义及用法: 指说话人给予的许可。也可是一般的许可。同can相比may和might用于比较正式文体，往往含有尊敬之意。might 表示比较迟疑，婉转。不很常用。You may smoke.你可以吸烟。 Visitors may ascend the tower. 参观者可以登塔。You might post this letter for me. 是否请你给我寄一下封信。May I make a suggestion? 我可以提个建议？ Might I borrow your bike?我借用你的自行车可以吗？回答形式:一般用于肯定，疑问和否定句。否定用于拒绝给予许可，或禁止做某事。通常在官方公告中，否定情态动词Students may not stay out after midnight. 学生午夜后不得在外逗留。用于问句和条件句表示请求。If I may say so, you are not right.你是不对的，如果我可以这么说的话。May I go now? No, you may.我现在可以走了吗？否定回答，一般用mustnt 或cannot， 也可以 may not。May I come in? 我可以进去吗？No, you mustnt. 不，你不许进。肯定回答，一般是 sure, certainly, of course,不能用mightMight I trouble you for a light?“You may indeed.”“我可以向你借火吗？”“当然可以要注意，在请求允许的用法中，might 并不是过去时，它指的都是将来时。 三、must的用法 1.表示必须、应该(否定形式用neednt或dont have to )。例如: -Must I finish the work before dark? -No, you neednt / dont have to. You may leave it for tomorrow. 2.must not (mustnt)表示强烈禁止。例如: You mustnt get to school late. 3.表示推测,只用在肯定句中,一定、想必之意。其否定意义不可能,用cant be形式。例如: -The light in her room is still on; she must be at home now. -She cant be at home. I saw her out just ten minutes ago. She forgot to turn off her light. 4.must和have to的区别: must表示说话人的主观看法;而have to强调客观情况迫使人不得不;must只能表示现在必须,表示过去的事情要用had to;have to有时态、人称和数的变化。must和have to的否定意思不同。比较: You mustnt do that.(你千万不能做那件事。) You dont have to do that.(你不必做那件事情。) 四、 need的用法 need作情态动词时表示需要,主要用于否定句和疑问句。例如: -Need we finish the work today? -Yes, you must. / No, you neednt.注意:作动词时need的句型:need sb doing /need sb to do sth.它的否定形式和疑问形式均不一样二.选择题:1- Shall I tell John about it?- No, you _.
