中考语法--情态动词专项讲解与练习 情态动词本身有各种意义，但不能单独作谓语，只能和主要动词一起构成谓语，表示说话人的       和          ，这样的动词称为情态动词。情态动词没有       和          的变化。常用的情态动词有can, could, may, might, will, would, should, must, need, 等。 一、can, could的用法1. can的用法（1）表示       、       、         。如：Can you speak English? 中文：                    ？    Can you play the piano?                             ？She can swim fast, but I can’t.                         。I can see with my eyes.                                 。（2）表示       或者         。如：Can I help you? 我能帮助你吗？You can’t play basketball. 你不能玩篮球。Can you...？“请你……好吗？”表示说话人的请求；Can I...？“我可以……吗？”用来征求对方是否允许自己做某事。如在句末加上 please一词就显得更有礼貌了。例如：    Can you help me, please?                             ？You can use my dictionary.                            。（3）表示       ，意为“可能”，常用与否定句和疑问句中，此时can’t译为“       ”。如：Can the news be true? 这个消息会是真的吗？The moon can’t always be full. 月亮不可能常圆。 注意：can和be able to的用法和区别两者表示能力时用法相同，但can只有原形和过去式两种形式，在其他时态中要用be able to来表示。另外be able to常常指经过努力，花费了时间和劳力之后才能做到某事。如：Jim can’t speak English. 吉姆不会说英语。I’m sure you’ll be able to finish it quickly. 我相信你能迅速地完成。 2. could的用法（1）        的过去式，意为“能、会”，表示过去的能力、可能性或允许：如：He could write poems when he was 10. 他十岁时就会写诗。I could run faster then.那时我能跑得更快。It could be no better at that time.那时好得不能再好了。（2）在疑问句中，表示        的语气，此时could没有过去的意思。如：Could you do me a favour? 你能帮我个忙吗？ Exercise 11. Michael __________ be a policeman, for he's much too short.
  A. needn't     B. can't   C. shouldn't   D. won't2. The fire spread through the hotel very quickly but everyone  __________ get out.

Can 二、may, might的用法都表       或        ，might可以指过去时间，也可指现在时间，语气更委婉。如：You may take whatever you like. 你喜欢什么就拿什么。May (Might) I ask for a photo of your baby? 我可以要一张你宝宝的照片吗？May I come in？我可以进来吗？在回答以may引起的问句时，多避免用这个词，而用其它方式，如Yes, please. / Certainly. / Please don’t ./ You’d better not. / No, you mustn’t.等，以免显得太严峻或不客气。 Exercise 21.--Is John coming by train?     --He should, but he __________ not.

Need you go so early? 才八点。你需要去这么早吗？Yes, I must. / No, I needn't.是的，我必须去/ 不，我不需要了。You needn't tell him about it as I have told him. 你不必跟他说那件事，我已经告诉他了。 Exercise 61. --Must I stay at home, Mum?        --No, you ______.  A. needn’t          B. mustn’t           C. don’t             D. may not2. --How long ______ the book be kept?--For two weeks, but you ______ return it on time.A. can; may         B. may; need         C. can; must          D. must; need 七、had better的用法表示“         ”，相当于一个助动词，只有一种形式，后面要跟动词原形，否定词形式为              。如：It is pretty cold.
