--Can you fly？ --No, I can‘t. (引出情态动词的结构) Step 2: 专题精讲 情态动词本身有一定的词义，但需与动词原形一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后通常加动词原形。 1. can and cannot 我们用can表示某人具备某种能力做某事，如I can play basketball. 其否定形式为can‘t或cannot， 如I can‘t swim. 疑问句中，把can提到句首，将can与主语的位置对调。如Can you speak any foreign languages? 2. may and may not 在请求对方的许可，或是准许你做某事时，常用情态动词may和can。may比较正式，can较常用且更口语化。 ----May I leave work early today? ----Yes, you may. No, you may not. You may/can use my computer. 3. must and must not must 用以表示―必须做某事‖或―一定要做某事‖，具有强制性，表示一种责任或义务或表示很有必要要做某事；或在提出建议时使用，意为―应该，得‖。 We must obey the school rules. It‘s a fantastic film. You must see it. Must的否定形式为must not 或mustn‘t，表示禁止，绝不允许，具有强制性。 I must hurry. I mustn‘t be late. You mustn‘t forget to call Julia. must 用于一般疑问句中时，其肯定和否定回答应引起我们的注意。 ----Must we go now? 我们现在一定要走吗？ ----Yes, we must. 是的，我们一定要走。 ---No, we mustn‘t. 不，我们不可以走。 常见情态动词有关的基本句型： A.陈述句 情态动词 can may shall should must have（has）to had better 肯定句 主语 + can + 动词原形 主语 + may + 动词原形 主语 + shall + 动词原形 主语 + should + 动词原形 主语 + must + 动词原形 主语 + have（has）to + 动词原形 主语 + had better + 动词原形 否定句 主语 + can + not + 动词原形 主语 + may + not + 动词原形 主语 + shall + not + 动词原形 主语 + should + not + 动词原形 主语 + must + not + 动词原形 主语 + don‘t（doesn‘t）+ have（has）to + 动词原形 主语 + had better + not + 动词原形 6
