Could Can you help me? - Yes, of course.Certainly. Sure. Could Can you tell me the way to the Zoo?3) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。 Can this be true? This cant be done by him. How can this be true? 二、 may1) 表示请求和允许。否定回答时可用cant 或mustnt，表示“不可以，禁止”。 - May I smoke in this room? - No, you mustnt. - May I take this book out of the room? - Yes, you can. (No, you cant / mustnt) 用May I.？征徇对方许可时比较正式和客气，而用Can I.？在口语中更常见。2）表示推测、可能性（不用于疑问句）。 1He may be very busy now. 2Your mother may not know the truth. 3）用于祈使句，表示祝愿。 May you succeed! 三、 must, have to 1) must表示必须、必要, 带有命令强制口气；而have to表示不得不，很勉强，强调客观需要。You must come in time. We must help each other.My sister is ill; my mother has to look after her.I had to work when I was your age.注意：must的否定形式mustnt表示禁止，意思是“不能，不许”。 在回答由must引起的疑问句时，如果是否定的，不能用mustnt（禁止，不准），而用neednt, dont have to（不必要）。- Must we hand in our exercise books today? - Yes, you must. - No, you dont have to / you neednt. 2) must表示推测、可能性（只用于肯定的陈述句），意思为“一定是,必然”。 1 Youre Toms good friend, so you must know what he likes best. 2 Your mother must be waiting for you now. 四、 shall,1) shall 用于第一人称，征求对方的意见。 What shall we do this evening? 2) shall 用于第二、三人称，表示说话人给对方的命令、警告、允诺或威胁。 1. You shall fail if you dont work hard.(警告) 2. He shall have the book when I finish it.(允诺) 3. He shall be punished.(威胁) 五、 should和shouldnt表示 应该 劝告、建议。 I should help her because she is in trouble. You should go to class right away.She shouldnt play computer games too much.六、will （过去式would）1) 做助动词，表示一般将来时，将要。He will be home at six.Bob will leave school next month.2) 作为情态动词时表示“愿意”“意愿”“会”。I will help you.I will never do that again.Will / Would you pass me the ball, please?相关练习：(一) 用适当的情态动词填空。1.
