常见的情态动词有

①常见的情态动词有：can (could) ,may (might), must ,shall (should), will (would), dare (dared) , need等,另外,have to、had better也当作情态动词使用。情态动词后面必须加动词的原形。 ②can表示体力、脑力方面的能力或客观的可能性。口语中, 在询问或说明一件事可不可以做时,常用“can”代替“may”。情态动词“can”的过去式是“could”,否定式是“cannot”通常缩写成“can’t”,“could”的否定式是“could not”,通常缩写成“couldn’t”。如：Can I help you?(要帮忙吗？) / He can swim.(他会游泳) / That can’t be Mr Li.(那不可能是李先生) ③may表示允许、请求或可能性,用may提问时,肯定回答一般用Certainly或Yes,you may.;否定回答一般用can’t或mustn’t. 如：May I ask you a question?—Certainly.(可以问你一个问题吗？当然可以) / You may go now.(现在你可以走了) / It may be in your pocket.(它可能在你的衣袋里) ④must表示“必须”、“一定”的意思。表示“必须”时否定形式是mustn’t；表示“一定”时,否定形式是“can’t”如：We must be very careful when we cross the road.(我们过马路时一定要非常小心)/ It must be Jack.(那准是杰克)/ I haven’t seen Kate today. She can’t be here.(我今天没有看到过凯特,她不可能在这里) [注意]用must(必须)进行提问时,肯定回答用must,否定回答用needn’t；用must(一定)进行提问时,肯定回答仍用must,但是否定回答用can’t. 如：Must we clean the room before we leave? –Yes,you must.或No,you needn’t.(我们走之前必须要打扫房间吗？是的,必须打扫。/ 不,不需要。) / Must she be in the romm? –Yes,she must.或No,she c an’t.(她一定在房间里吗？是的,一定。/ 不,不可能在。) ⑤“have to”表示“不得不”、“必须”。We’ll have to leave now for it is very late at night. have to的疑问形式是：助动词+…+have to,否定形式是：助动词+not+have to或者用needn’t.如：Do you have to stay until 8 o’clock?(你得呆到8点钟吗？)/ You don’t have to do so.(=You nee dn’t do so.)(你不用这么做) ⑥shall在问句中,可表示征求对方意见,与第一人称连用；在陈述句的第二、三人称的主语后或表示“命令”、“警告”、“允许”等。如：Shall we go to the zoo this weekend?(我们这个周末去动物园好吗？) / He shall bring his own book next time.(他下次必须带自己的书来) ⑦should可表示“劝告”、“建议”、“惊奇”等意思。 We should speak to old people politely.(我们应该礼貌地对老人讲话) ⑧will表示“意愿”、“决心”等意思,一般与第二人称连用。如：Will you please close the door for me?(请你替我把门关上好吗？) / I will teach you a lesson.(我要教训你一顿) ⑨would表示过去的“意愿”、“决心”等。 He would sit near the fire every time he returned home.(每次他回到家中总要坐在火炉边) would也可以表示现在的情况,表达说话人向对方提出的要求,语气比“will”婉转、客气。在日常会话中,“我想要…”通常用“I would like to”或“I should(I’d) like to”来表示。如：Would you like to have a rest at the moment?(你现在想要休息一下吗？) would还可以表示过去经常发生的事情。如：Every year parents would tell their children about the boy who would save his people.(每一年父母们总是向孩子们讲述这个将会拯救他的人民的男孩的事) ⑩need表示“需要”,用于疑问句或否定句。“need”作实义动词时,在肯定、否定、疑问句中都可以用。如： He needn’t do it in such a hurry.(他不需要如此匆忙地做这件事) / He needs some help.(他需要一些帮助) / He doesn’t need to bring his football socks then.(那么他就无须带上足球袜了)
