考点小资料：情态动词
I. can (could), 表示体力或脑力方面的能力，或根据客观规律能做某事的能力，意思是“能够”。can表“能够”时，既可指将来，也可指现在。be able to在表示能力时与can同义，但可用于各种时态，强调通过努力克服困难成功地做成某事，相当于managed to do 或 succeeded in doing。表示许可、允许，在疑问句中表示“请求，许可”，否定句中表示“不许”，此时可与may通用，有时cannot可以表示“禁止”，相当于“mustn’t”。表示推测，强调客观可能性“可能、会”，can多用于疑问句和否定句，表示猜测时，情态动词后可用进行式或完成式。
could表示“能力”“可能性”“许可”，为can的过去式。一般用于委婉、客气地提出问题或陈述看法，此时can，could并没有时间上的差别，只是could的语气更客气些。回答时用原形回答。
II. may (might), 表示许可，有“可以”的意思，询问一件事可不可以做，有时可以与can互换。其否定式may not表示“不可以、禁止、阻止”等，常用must not=mustn’t代替，may用于疑问句中，回答这种问题时，多避免用may，而用其他形式，以免显得口气太严峻或不客气。
表推测、或许、可能的意思，表示一件事或许会发生，只用在陈述句中。
表祝愿: May you succeed! = I hope you may succeed. May you be happy, healthy and wealthy!
might是may的过去式，表示可以做的事或可能发生的事；主句谓语动词是过去时态时用 might不用may。might一般用于比may的口气委婉，或表示现实的可能性更小一些的语境中。
III. must, have to, 表示必须要做的事，意为“必须“，否定式 mustn’t表示“不应该，不许可，禁止”等。因此，在回答带有must的问句时，不用mustn’t，而用 needn’t或don’t have to.
must在表示“必须”时与have to相近，have to比较强调客观的需要，must着重主观看法。另外must不像have to那样能有更多的时态。表推测，暗含很大的可能性，意为“一定”，只用于“肯定句”中。偏偏、硬要、干嘛(指做令人不快的事)。如： Hey．boys！ Must you shout so loudly?
IV. shall, 用于二、三人称陈述句中。表示说话人给对方的命令、许诺、警告、强制、威胁、决心等。在疑问句中，表示征询听话人是否愿意。用于一、三人称的疑问句中，表示说话人征求对方的意见和向对方请示。
should表示劝告、建议常作“应当”讲，与ought to有时可互换，ought to更注重一些责任义务。should表示预测可能性，并译作“可能，(按道理)应该”；而ought协则表示非常可能。should用于委婉、谦逊地提出意见或建议，ought to可表示因责任、义务等该做的事。
V. will, would, 表示意愿、意志和决心，适用于各种人称，可以用来表示各种倾向或习惯动作。有时还用来表示“难免”。其过去式是would，也可以是单独的情态动词，在表示委婉提出请求、建议或看法时，语气比will委婉，肯定的回答时用will.
VI. may well和may/ might as well后都接动词原形，是一种常用结构。may well+动词原形相当于 to be likely to，意为“(完全)能，很可能”。may/ might as well+动词原形相当于had better或幻have no strong reason not to，意为“最好，不妨”。cannot…too/enough表示“无论怎么……也不过分”，“越……越好”；cannot but do sth．表示“不得不，只好”的含义。
