情态动词can的用法
一、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，其用法如下：
二、can的用法
1.表示能力，意为“能，会”。如：
Can you swim？你会游泳吗？
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？
3.用于提出邀请。
（1）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。
如：—Can he come to my party？他能来参加我的宴会吗？
—Yes. .是的。他很乐意。
（2）用于提出邀请的句型还有：
1.Would you like (come) to my party
2.Do you want (come) to my party
3.How about (come)to my party
4.I'd like (invite)you to come to my party.
5.Let's (go) to the movies tomorrow.
6.Shall we (go) to the movies tomorrow
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。
三、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。如：
—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。如：
—Can I see your guitar？我能看看你的吉他吗？—Certainly.当然可以。
4、can和could对比
(1)could是can的过去式，表示过去的能力，意为“能，会”。
例如：Could you speak English at the age of six
(2)can和could 问句中，表示请求或征得对方同意，意为“我可以或你可以．．．吗？”，此时 could 不是can的过去式，而是一种委婉表达。出于礼貌，有时候还会加上please，构成 Can you please...？ Could you please..？句型。回答的时候，用can 作答。
Eg．1．--你能把电视调小一点吗？ / you please turn down your TV a little
--我当然可以。Of course，I .
2.--我晚上可以和朋友出门逛会吗？ I out withe friends at night
--No,you .You have to go to bed early.
