B: Yes, you can. / No, you cant. 2. 在否定、疑問句中表示推測或懷疑用couldnt。 He couldnt be a bad man. 他不大可能是壞人。,may和might 表示允許或請求; 表示沒有把握的推測; may

8、放在句首, 表示祝愿。 May God bless you! He might be at home. 注意: might 表示推測時, 不表示時態(tài)，只是可能性比may小。,1. 兩詞都是 “必須”的意思, have to 表示客觀的需要, must 表示 說話人主觀上的看法, 既主觀 上的必要。,have to和must,My brother was very ill, so I had to call the doctor in the middle of the night. 我弟弟病得很厲害,我只得半夜里 把醫(yī)生請來。(客觀上需要做這件事) He said that they must

9、 work hard. 他說他們必須努力工作。 (主觀上要做這件事),2. have to有人稱、數(shù)、時態(tài)的變化,而must只有一種形式。但must 可用于間接引語中表示過去的必要或義務(wù)。 He had to look after his sister yesterday.,3. 在否定結(jié)構(gòu)中: dont have to 表示 “不必”, mustnt 表示“禁止”。 You dont have to tell him about it. 你不一定要把此事告訴他。 You mustnt tell him about it.你一定不要把這件事告訴他。,用情態(tài)動詞can/could, cant,
