2、一般過(guò)去式；而be able to則有更多的時(shí)態(tài)。Ill not be able to come this afternoon. 當(dāng)表示“經(jīng)過(guò)努力才得以做成功某事”時(shí)應(yīng)用be able to，不能用Can。如：He was able to go to the party yesterday evening in spite of the heavy rain. 2) 表示請(qǐng)求和允許。-Can I go now? - Yes, you can. / No, you cant. 此時(shí)可及may互換。在疑問(wèn)句中還可用could, might代替，不是過(guò)去式，只是語(yǔ)氣更委婉，不能用于肯定句和答語(yǔ)中。-

4、 may, might 1) 表示請(qǐng)求和允許。might比 may語(yǔ)氣更委婉，而不是過(guò)去式。否定回答時(shí)可用cant 或mustnt，表示“不可以，禁止”。-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(duì)方許可時(shí)比較正式和客氣，而用Can I.？在口語(yǔ)中更常見(jiàn)。2）用于祈使句，表示祝愿。May you succeed! 3) 表示推測(cè)、可能性（不

6、ve to / you neednt. 2) must是說(shuō)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(shí)， have to 有更多的時(shí)態(tài)形式。1His play isnt interesting, I really must go now. 2 I had to work when I was your age. 3) 表示推測(cè)、可能性（只用于肯定的陳述句）1 Youre Toms good friend, so you must know what he likes best. 2 Your mother must be waiting for you now. 四、

7、need 1) need 作情態(tài)動(dòng)詞用時(shí), 常用于疑問(wèn)句、否定句。在肯定句中一般用must, have to, ought to, should代替。1You neednt come so early. 2. - Need I finish the work today? - Yes, you must. / No, you neednt. 注意:對(duì)must構(gòu)成的一般疑問(wèn)句作否定回答只能用needn't. 實(shí)戰(zhàn)練習(xí)一英漢互譯1.節(jié)約能源 _ 2.浪費(fèi)水_3.砍伐樹(shù)木 _ 4.保護(hù)地球_5.收集塑料瓶_6.使用紙袋和玻璃杯_7.makea poster_8.use too much pl
