情态动词can, must, need 和had better
表示“许可、可以”1. 用于肯定句、否定句和疑问句。2. 否定形式为can’t, 表示“不能、不可以”，语气弱于mustn’t。3. 在回答以can 开头的一般疑问句时，肯定回答用can, 否定回答用can’t 或mustn’t。
4. 表示请求时，culd 比can 的语气更委婉，但回答culd 表示的请求时，要用can。e.g. Yu can take the car, if yu want.如果你想的话，你可以乘坐那辆车。Yu can’t park here—it’s a n-parking zne. 你不能在这里停车—— 这是非停车区。—Can I read yur newspaper? 我可以看一下你的报纸吗？—Yes, yu can./N, yu can’t. 是的，你可以。/ 不，你不可以。
表示能力，意为“能，会”。e.g. He can answer the questin.他能回答那个问题。I can’t prmise anything, but I’ll d what I can. 我不能许诺什么，但我会尽力而为。
表示可能性，意为“有可能”。e.g. Can he still be alive after all this time?过了这么长时间，他还可能活着吗？
情态动词must表示“必须, 一定要”，此时可用于肯定句、否定句或疑问句，用于否定句时，mustn’t 的意思是“禁止，不能”，通常表示劝告、告诫，而不表示“不必”。对于以must 开头的一般疑问句，若作否定回答，可以用needn’t 或dn’t have t，不用mustn’t。
表示推测，意为“一定”，通常只用于肯定句。e.g. Jane’s light is n. She must be at hme. She can’t be ut. 简的灯开着。她一定在家。她不可能在外面。
must 与have t 都表示“必须”，但must 无人称和数的变化，并侧重于说话者的主观看法，认为有必要或有义务去做某事；have t 有多种形式的变化并侧重于客观需要，含有“不得不”，“被迫”之意。其否定形式为dn’t have t，相当于needn’t，意为“不必”。e.g. Everyne must bey the law. 人人都要守法。The last bus has gne. We’ll have t walk hme.最后一班公共汽车已经开走了。我们将不得不走回家。
情态动词needneed 用作情态动词，表示“需要”，主要用于否定句和疑问句。其否定形式是在need 后直接加nt，表示“不必”；疑问形式是把need 提到主语之前。由need 引出的一般疑问句，肯定回答常用must 或have t；否定回答常用needn’t。
had better 的用法had better 表示劝告或建议，意为“最好……”, 在句中常缩写为’d better。其后接动词原形，即had better d sth. 意为“最好做某事”。had better 一般不用于疑问句中，否定句的形式为had better nt d sth. 意为“最好不要做某事”。e.g. Yu lk tired. Yu’d better lie in bed and have a gd rest. 你看起来累了。你最好躺在床上好好休息。
1.当你第一次见到某个人时, 你必须说先生或女士。 Yu _____ say Mr r Mrs when yu meet smene fr the first time.2.你可以带走它。 Yu _____take it away.3.你不许打坏任何东西。 Yu ______break anything. 4.你不需要等。 Yu _____ wait!
