02 重点情态动词的用法

No.1 can/could

①表能力 意为“能;会”; can't意为“不能;不会”

can/could=be able to【将来时和完成时只能用be able to】

be able to 用于表示经过努力而成功地办成某事，相当于succeed in/manage to do 此时不能can.

e.g.His mother couldn’tafford to pay for her child’s education.

=His mother wasn’t able toafford to pay for her child’s education.

②表请求允许 意为“可以” 此时could比can语气更委婉 更客气 不要理解为是can的过去式。

could一般用于疑问句中 回答时可用can.礼貌用语“Could you please...”中的please可以放在句尾。

e.g.--Could you please take out the rubbish?--Yes sure.(=Yes I can.)

e.g.--Could we get something to drink after movie?--No you can’t.

③表示可能性 常用于疑问句和否定句中，指“某事是否是事实”。【简单了解】

e.g.Can the story be true?这个故事可能是真的吗？

④表推测，多用于否定推测，can’t be/couldn't be一定不是，此时could不表示时态，只表示可能性比can小。即can>could(可能性)
