I wonder if you could help me. (request) Excuse me, could you tell me the way to the station?a. can 表示泛指的“可能”，并非说话者主观认为的可能性，即并非说话者的主观猜测。Accident can happen to any drunken driver. b.表示说话者主观猜测，只能用与否定句或疑问句中。例如：It cant be my father. He is now in England. 二、may 和might ：1） 表示可能性（possibility）,用于对现在，过去或将来的推测，暗示不确定。might 不是may的过去式，它所表示的可能性比may 小，含较多的怀疑。He may be very busy now. (可能性较大)He might be very busy now. (可能性较小) 2） 表示许可（permission），表示允许别人做某事， 也可征求对方的许可。 He may go now. / We may keep the book for two weeks.3） 用于祈使句，表示祝愿。May you succeed! / May you have a nice trip! 三、will和would： 1）表示意愿 表示愿意做或主动提出做，如意志,愿望或决心That bag looks heavy, Ill help you with it.( offering to do sth)- You know that book I lent you. Can I have it back if youve finished with it?- Of course. Ill give it to you this afternoon.(agreement)Thanks for lending me the money, Ill pay you back on Friday. (promise) 2）表示习惯(habit, custom)This old man is strange. He will sit for hours without saying anything. We would sit around Grandpa after supper, listening to his stories.3）表示请求（request）, 用于第二人称, would 比will 更委婉。 例如：Will you come this way, please?Would you open the window? 四、shall和should：. a. shall 在疑问句中用于第一，第三人称，表示征求对方的意见。Shall we put off the sports meeting until next month?b.shall 用于第二，第三人称，表示说话人给对方的命令，警告，允诺或威胁。You shall fail if you dont work harder. （警告）He shall have the book when I finish reading it.(允诺) He shall be punished.(威胁) a. should 表示劝告、建议、命令。You should go to class right away.b. should 表示期待，用于表达合理推断（prediction，意为“应该” ），或明显的结果（意为“可能”）且所期待的事几乎是事实。It is three oclock, the football game should begin now. 五、must和cant： must 用来表示“命令”、“推测”等含义。1）表示规定、指令表示规定、指令时主要指客观上的法律、条文规定，常常翻译为“应该、必须”之类意思。mustnt表示禁止You must have a passport if you want to go abroad. 22) 表示主观的命令、禁止时，主要指说话者主观的命令或强烈的劝告。You can go out with your friend but you must come back before 11 at night. 3）表示猜测，语气非常肯定，近乎确定的意味，一般用于肯定句，意为肯定。其否定为cant，意为不可能. 。You must be ill. I can see it from your face.must和 haveto：1.must用于一般问句中,肯定回答用must否定式用neednt或dont have to，做“不必”,mustnt表示“禁止，不允许” 2.表示“必须”这个意思时，must和haveto稍有区别。must着重说明主观看法，haveto强调客观需要。“日清过关”巩固提升三级达标训练题基础题1 I dont like this TV set.
