情态动词can的用法
1.can是情态动词，没有人
称和数的变化，但有时态的变化，它的过去式为could,其后可直接接动词原形，总结它的用法如下：
(1)表示能力，意为“能，会”。如：
Can you swim？你会游泳吗？
Can you answer the question?你能回答这个问题吗？
(2)表示许可，意为“可以”，相当于may(比may更口语化
，may较正式)。此外，could也可以表示许可，语气更加委婉。如：
Can/May I come in?我可以进来吗？
Can you help me?你能帮我吗？
You may go home now.你现在可以回家了。
Could you help me find it?你能帮我找到它吗？
(3)用于提出邀请。对其作肯定回答通常用“Sure./Of course./Certainly./Yes, I’d love (like) to.”等，作否定回答通常用“Sorry/No, I can’t.
”等。
—Can he come to my party?他能来参加我的宴会吗？
—Yes. He’d love to.是的。他很乐意。
—Can you go to the baseball game?你能去看棒球比赛吗？
—Sorry, I can’t.对不起，我不能。
(4)用于否定句或疑问句中，表示推测。如：
Mr. Wang can’t be at home.王老师不可能在家里。
2.can句式变化
(1)在变否定句时，直接在后面加上“not”，写作can’t或cannot。如：
I can speak French.我会讲法语。
→I can’t speak French.我不会讲法语。
(2)在变一般疑问句时，can直接移到主语前(原主语的首字母改成小写，第一人称应变为第二人称)即可。如：
I can play the piano.我会弹钢琴。
→Can you play the piano?你会弹钢琴吗？
其肯定回答可用yes, OK或certainly等；否定回答可用no或sorry等。
—Can you look after my books, please?你能照看一下我的书吗？
—OK.可以。
用
certainly回答语气更为肯定。
—Can I see your guitar?我能看看你的吉他吗？
—Certainly.当然可以。
