could表示过去的能力，can表示现在或将来的能力。
拓 展
e.g. A hen can’t swim. 母鸡不会游泳。
I couldn’t play the piano until I was five years old.
直到五岁我才会弹钢琴。
情态动词can/could的用法

拓 展
e.g. Driving on these roads can be very dangerous.
在这些路上开车有时是非常危险的。
③ 在否定句和疑问句中，can表示可能性，有惊异、怀疑、不相信之意，这时can与could没有时间上的差异，只是could语气要轻一些。
e.g. How can that be true 这怎么可能？
What you said couldn’t be true. 你说的不可能是真的。

⑤当表示允许别人做某事时，用can而不用could。

—Could I use your phone for a while 我能用一下你的电话吗
—Yes, of course you can. 是的，你当然可以。

⑥表示提议和请求。在语气上could较客气，但can较肯定。

如果你太忙的话，我可以帮你做文书工作。
Could/Can you make some room for me, please
你能给我腾点地方吗

(1) both“两者都”，作they的同位语，它放在实义动词前，be动词和情态动词后。
e.g. We are both students.我们都是学生。
(2) both表示“两者都”；三者或者三者以上用all。
e.g. My parents are both teachers. 我的父母都是教师。
My friends all went to the park yesterday. 我的朋友们昨天都去公园了。
(3) Both of+复数代词 both （of the）+复数名词
