相当于情态动词的 have to, used to情态动词的语法特征1) 情态动词不能单独做谓语, 除ought和have外, 后面只能接不带to的不定式。 2) 情态动词没有人称, 数的变化, 但有些情态动词, 如can、will也有一般式和过去式的变化。3)?情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。can 和could：1) can的主要用法是：
? A.? 表示体力或脑力的能力：
? e.g. The girl can dance very well.
B.? 表示说话的推测﹑事物的可能性等:
e.g. Can the news be true?
C. 在口语中, can可以表示请求或允许:
e.g. Can I sit here? can表示“能够”时与短语be able to同义，但can只用于一般现在时或过去时，而后者可用于各种时态。另外，can表示个人有某种能力，而be able to表示某人通过努力、克服困难做成某事，相当于succeed in doing sth.；叙述过去事实时，最好用was / were able to，因为could只表示过去具有某种能力。如：
Can you understand the different kinds of English these people are using?
Two years later, he was able to speak very good Chinese.2) could的主要用法是：
A. could 是can的过去式, 表示与过去 有关的能力和推测:
e.g. We all knew that the young man
couldn’t be a doctor.
B. could可以代替can表示请求, 但语气较can客气、委婉: e.g. Could you lend me your dictionary?
Could I use your bike?
3) can和could接动词的完成形式，表示可能已经做某事。can用在否定和疑问句中, 表示不相信、怀疑等态度。
e.g. They can’t have gone out because the light is still on.以could或would提问时，不能再以could或would作答，而应该用can或will。如：
—Could I borrow your dictionary?
—Yes, of course you can.情态动词用法小结
