我们可以用can表达是否能做某事，如果是询问某人能不能做某事，则要使用can的疑问形式。如：

— Yes, I can. / No, I can't.

为cannot，也可以缩写为can't。

肯定句: 主 + can + 动词原形 …
否定句: 主 + can't + 动词原形 …
一般疑问句: Can + 主 + 动词原形 …？

否定回答:

We use can to talk about present ability.

2. 用can,could和may来表示征求许可
1) can 与 could
can 常用于口语中，表示非正式的请求，请求对象一般是家人或朋友。e.g.
— Can I borrow your bike, Simon
西蒙, 我可以借一下你的自行车吗？
— Of course.
当然可以。
— Can I have some milk, Mum
妈妈，我可以喝点牛奶吗？
— Yes, you can. 好的。
could是can的过去式。在口语中，could常用来代替can向对方更委婉地提出请求，用法上比can正式，可以用于向老师或长辈提出请求，这时could不表示过去，回答一般还是用can。e.g.
— Could I use your computer, please
请问，我可以用一下你的电脑吗？
— Yes, you can. 可以。
— Could I hand in our homework later, Mr Lin
林老师，我可以稍后交作业吗？
— No, you can't. 不，不行。
2) may
may也可以用来征求对方意见，意为“可以”，相当于could，用法也比can更正式，更礼貌，一般用于向陌生人或所尊敬的人请求许可。e.g.
— May I ask you a question
我可以问你一个问题吗？
— Yes, please. 可以，请问。
— May I come in, Mr Wu
吴老师，我可以进来吗？
