She said she would go there. - No. She _ be there, I have just been there.A.cant B.mustnt C.neednt D.wouldnt 随堂练习：-Is John coming by train? -He should, but he _ not. He likes driving his car. A. must B. can C. need D. may2.could的用法（1） can的过去式， 意为“ 能、 会” ， 表示过去的能力。 如：He could write poems when he was 10. 他十岁时就会写诗。（2）could 在疑问句中， 表示委婉的语气， 此时 could 没有过去式的意思。如:Could you do me a favour? 你能帮我个忙吗？-Could I use your pen? 我能用一下你的钢笔吗?-Yes, you can. 可以。例. _ I take it out? Im sorry, you _.A. Could .couldnt B. Might.might notC. Could.can D. May.cant3.may的用法（1） 表示请求、许可， 比can 正式You may go home now. 现在你可以回家了。例-_ I borrow your MP3?-Sure . Here you are.A. May B.Should C.Must D. Would(2)表示推测，谈论可能性，意为“ 可能， 或许”，一般用于肯定句中 It may rain tomorrow . 明天可能会下雨(3) may的过去式为might ，表示推测时。可能性低于mayHe is away from school. He might be sick.4. must的用法(1) must 表示主观看法，意为“必须、一定”Must I hand in my homework right now?(2) 其否定形式mustnt表示“ 一定不要 ” “千万别” “禁止, 不许”.You mustnt play with fire. 你不许玩火。对must引导的疑问句，肯定回答为must， 否定回答为neednt 或 dont have to .如：-Must I finish my homework? -No, you neednt.(4)must 表示有把握的推测，用于肯定句。如: The light is on, so he must be at home now.5. need的用法（1） need 表示需要、必须，主要用于否定句和疑问句中，其否定形式为neednt，意为“没有必要，不必”。 用need 提问时，肯定回答为 must，否定回答为 neednt 。 如：-Need I stay here any longer? 我还有必要留在这儿吗？-Yes, you must .是的。(2) need 还可以作实义动词，此时有人称、数和时态的变化， 后边多接动词不定式。如：I need to do it right now. 我需要马上做这件事。 He needs to learn more about the girl. 他需要多了解那个女孩T(实练)1.
