(No, Im afraid not.) 3) 表示客觀可能性（客觀原因形成的能力）。例如： Theyve changed the timetable, so we can go by bus instead. This hall can hold 500 people at least. 4) 表示推測（驚訝、懷疑、不相信的態(tài)度），用于疑問句、否定句和感嘆句中。 Can this be true? This cant be done by him. How can this be true? 教學(xué)環(huán)節(jié)教學(xué)內(nèi)容措施矯正交流展示任務(wù)、討論、展示2. may, might 1) 表示請求和允許。might比 may語氣更委婉，而不是過去式。否定回答時可用cant 或mustnt，表示“不可以，禁止”。 例如：-Might/ May I smoke in this room? - No, you mustnt. - May/Might I take this book out of the room? - Yes, you can. (No, you cant / mustnt. ) 用May I.？征徇對方許可時比較正式和客氣，而用Can I.？在口語中更常見。 2）用于祈使句，表示祝愿。 例如：May you succeed! 3) 表示推測、可能性（不用于疑問句）。might不是過去式，它所表示的可能性比may小。 例如：He may /might be very busy now. Your mother may /might not know the truth. 3. must, have to 1) 表示必須、必要。例如： You must e in time. 在回答引出的問句時，如果是否定的，不能用mustnt（禁止，不準(zhǔn)），而用neednt, dont have to（不必）。例如： - Must we hand in our exercise books today? - Yes, you must. - No, you dont have to / you neednt. 2) must是說話人的主觀看法，而have to則強(qiáng)調(diào)客觀需要。Must只有一般現(xiàn)在時，have to 有更多的時態(tài)形式。 例如：His play isnt interesting, I really must go now. I had to work when I was your age. 3) 表示推測、可能性（只用于肯定的陳述句）例如： Youre Toms good friend, so you must know what he likes best. Your mother must be waiting for you now.4. dare, need 1) dare作情態(tài)動詞用時, 常用于疑問句、否定句和條件從句中, 過去式形式為dared。例如： How dare you say Im unfair? 2) need 作情態(tài)動詞用時, 常用于疑問句、否定句。在肯定句中一般用must, have to, ought to, should代替。 例如：You neednt e so early. - Need I finish the work today? - Yes, you must. / No, you neednt. 3) dare和 need作實(shí)義動詞用時， 有人稱、時態(tài)和數(shù)的變化。在肯定句中，dare后面常接帶to的不定式。在疑問句和否定句中，dare后面可接帶to或不帶to的不定式。而need后面只能接帶to的不定式。 例如：I dare to swim across this river. He doesnt dare (to) answer. 5. shall, should 1) shall 用于第一人稱，征求對方的意見。 例如：What shall we do this evening? 2) shall 用于第二、三人稱，表示說話人給對方的命令、警告、允諾或威脅。 You shall fail if you dont work hard. (警告) He shall have the book when I finish it.(允諾) He shall be punished.(威脅)教學(xué)環(huán)節(jié)教學(xué)內(nèi)容措施矯正交流展示任務(wù)、討論、展示 6. will, would 1) 表示請求、建議等，would更委婉。例如： Will / Would you pass me the ball, please? 2) 表示意志、愿望和決心。例如： I will never do that again. They asked him if he would go abroad. 3) would表示過去反復(fù)發(fā)生的動作或某種傾向。would表示過去習(xí)慣時比used to正式，且沒有“現(xiàn)已無此習(xí)慣”的含義。例如： During the vacation, he would visit me every other day. The wound would not heal.7. should, ought to 1) should, ought to表示“應(yīng)該”，ought to表示義務(wù)或責(zé)任，比should語氣重。 I should help her because she is in trouble. You ought to take care of the baby. 2) 表示勸告、建議和命令。should, ought to可通用，但在疑問句中常用should。 You should / ought to go to class right away. Should I open the window? 3) 表示推測 should , ought to (客觀推測), must(主觀推測)。 He must be home by now. (斷定他已到家) He ought to/should be home by now.(不太肯定) This is where the oil must be. (直爽) This is where the oil ought to/should be. (含蓄)一，選用can, could, may, must, shall, should, will, would, cant, mustnt, neednt或have to 1. There is air around us, thought we _ see it.2.
