Here you are.2. 表示可能性时，常用在肯定句中，意为“可能、也许”He may be very busy now.He said that she might not be at work today.3. can和may都可以表示推测。Can通常用在否定句和疑问句中，may通常用在肯定句和否定句中。虽然两者都可以用于否定句，但是程度不同，cant的语气比may not更强。It cant be true.It may not be true.4. 表示希望、祈求、祝愿，常可以译为“祝愿”May you have a good time.May you be happy.5. might可以作为may的过去式，也可以在提出请求时表委婉；在表示可能性时，might的可能性比may更小注意：can和may的区别1. can和may都可以表示“许可”，在征求对方意见时用may比较多 May I go now?2. 在询问客观上是否可以时，用can Can we take the books out?3. 在两者都可以用时，may更客气一些4. 在陈述句中用can比较多 You can sit here.5. can还可以表示能力，may无此用法6. 在否定句中一般不用may not，常用cant表示不可能He cant be at home tonight.四、must1. 表示“必须、一定要”，多强调说话人的主观看法（表示客观需要时，常用_） 否定式mustnt表示“一定不要，禁止” You must see the doctor. Must you go soon? 对于must开头的一般疑问句，如果要做否定回答，可以用neednt, dont have to，不能用mustnt -Must I come over tonight? -No, you neednt2. 表示推测，意为“准是，一定是”，但是通常只用于肯定句，在否定句、疑问句中通常用cantIt must be true.Can it be true?
