39、示推测， 意为“可能”， 常用于否定句和疑问句中，此时 cant 译为“不可能”。如：Can the news be true?这个消息会是真的吗？Can it be our teacher?那个人有可能是我们老师吗？No, it cant be our teacher. Heis on a visit to the Great Wall.不可能。咱们老师正在游览长城呢。I think Miss Gao must be in the library. She saidshe would go there.No. She _be there, I have justbeen there.根据下文

40、“我刚去过那儿”可知，应为“不可能”，cant 表示推测答案 2. could 的用法： .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。 . 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 你能帮我个忙吗？Could I use your pen?我能用一下你的钢笔吗?Yes, youcan.可以。 3. may 的用法： .表示请求、许可，比 can 正式，如：May I borrow yourbike?我可以借你的自行车吗？

He might - 1 - be sick.他离开学校

42、了，可能是他生病了。 . 表示希望、祈求、祝愿，常可译为“祝愿”。通常是用 may +主+V 例如：May you have a good time.祝你过得愉快。May you be happy!祝你幸福！May you succeed！祝你成功！ 4. must 的用法： .must 表示主观看法， 意为“必须、 一定”。 如： You muststay here until I come back.在我回来之前你必须呆在这儿。Must I hand in my homework right now? 我必须现在交作业吗？对 must 引导的疑问句，肯定回答为 must，否定回答或dont

43、 have to .如：Must I finish my homework?我现在必须完成作业吗 must 表示有把握的推测，用于肯定句。如: The lightis on, so he must be at home now. 灯亮着，他现在肯定在家。注意其反意问句的构成形式：当 must 表示肯定的判断、推测时，其反意疑问句要用实际问句的助动词来构成。如：She must have seen the filmbefore, hasnt she?You must have met uncle Wang in theshop yesterday，didnt you? 5. need 的用法：

44、.need 表示需要、必须，主要用于否定句和疑问句中， ，意为“没有必要，不必”。用 need 提问时，肯定回答 dont have to。如：Need I stay here any longer? 我还有必要留在这儿吗？Yes, you must .是的。 No. you neednt /dont have to.不，你不必。 .need 还可以作实义动词，此时有人称、数和时态的变化，如果是人作主语后边多接动词不定式。如： I need to doit right now.我需要马上做这件事。He needs to learn moreabout the girl.他需要多了解那个女孩。如

45、果是物作主语， 一般用need doing与need to be done这种情况下应注意两点：.主动形式的动名词 doing 具有被动的含义；.该动名词可以改为其动词不定式的被动形式而句子的意义不变。例如：. The door needs painting. = The door needsto be painted.那扇门需要油漆一下。Your car needsmending. = Your car needs to be repaired. 你的车需要维修了。 7. shall 的用法： shall 表示征求对方意见，如：Shall we go out for awalk?我们出去散步

46、好吗？在英语中，我们可以用其他多种方式提出我们的建议或征求对方意见。 .用“Lets do.”来提出建议。如：Lets go fora walk after supper. - - .用“What/How about.?”来提出建议；about 后接名词或动词 ing 形式。 如： What about/How about a drink? Whatabout/How about taking Tom with us? .用“Why not.?”来提出建议，表示“何不?”not面后接动词原形。“Why not.?”实际上是“Why dontyou/we.?”的简略形式。如：Why not me

47、et at the schoolgate at eight? Why dont we stay here another day? .用“Would you like.?”来提出建议，意思是“你想要?吗?”Would you like 后可接名词或不定式。 如： Wouldyou like a cup of tea? Would you like to go and see her?因此，如果我们说：“去游泳好吗?”英语中可有这样几种表达法：Shall we go for a swim? Lets go for a swim，shall we? What about/How about goi

48、ng swimming? Why notgo for a swim? Would you like to go for a swim?

49、表示意愿、意志、打算，可用于多种人称。如： Iwill help you if Im free this afternoon.今天下午如果我有空，我就会帮你。注意： 1、will 在 there be 句型中的形式及其句式变换。由于“一般将来时”的结构可以用“will+动词原形”来表示，所以 there be 句型的一般将来时的形式就是there will be。例如：There are many students in ourschool.There will be many students in our school.There will be a sports meeting next

50、 week.一定不能说：There will have a sports meeting next week. 2、will 与 be going to do something 区别：. be going to 表示近期、 眼下就要发生的事情， will表示的将来时间则较远一些，如：He is going to write aletter tonight. He will write a book one day. be going to表示根据主观判断将来肯定发生的事情，will 表示客观上将来势必发生的事情。He is seriouslyill. He is going to die.H
