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,其用法如下:
(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 to.”等,作否定回答通常用“Sorry/No,I can't.”等。
如:
—Can he come to my party?他能来参加我的派对吗?
—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的句式变化
(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。
