情态动词can
情态动词有一定的意义, 但无人称和数的形式上的变化; 通常后接不带to的动词不定式, 表示说话人的语气和情态。其否定式的构成是: 情态动词+not (cannot=can’t)。
请根据所给句子归纳can的用法。
I / We / You can sing and dance.
He / They can swim.
(1) can表示能力（如体力和脑力方面），意为“能；会”等。
e.g. That big cinema can seat 2,000 people.
那家大电影院能坐 2,000人。
Temperature can reach 35 degree℃ in the summer here.
这儿夏天的气温能达到35摄氏度。
(2) 表示客观可能性，意为 “可以，可能”。
You can have the book when I have finished it.
这本书我看完了，可以给你。
—Can I go now
—Yes, you can.
—现在我能走了吗？
—是的，你可以了。
(3) 表示允许（和may意思相近），意为 “可以”。
e.g. Jane and Jack cannot / can’t speak English.
—Can she play the piano
—Yes, she can. / No, she can’t.
can的否定式为cannot，可缩写为can’t；含有can的一般疑问句是将can提到句首，其肯定回答为Yes, 主语+can.，否定回答为No, 主语+can’t。
肯定 I can play football.
You can swim.
否定 I cannot (can’t) play football.
You cannot (can’t) swim.
一般疑问句 Can you swim
回答 Yes, I can. /No, I can’t.
肯定 He / She can speak English.
It can speak like a man.
否定 He / She cannot (can’t) speak English.
It cannot (can’t) speak like a man.
一般疑问句 Can he / she speak English
Can it speak like a man
回答 Yes, he / she can. No, he / she can’t.
Yes, it can. No, it can’t.
肯定 We can swim.
They can play table tennis.
否定 We cannot (can’t) swim.
They cannot (can’t) play table tennis.
一般疑问句 Can you swim
Can they play table tennis
回答 Yes, we can. No, we can’t.
Yes, they can. No, they can’t.
区别:
can能用来表示人或者事物的能力。
be able to只能用来表示人的能力。
e.g. I can get best score in every match.
我能在每次比赛中得最高分。
I’d love to be able to sing like you.
我要是能像你那样唱歌就好了。
相似点: can和be able to都表示“能力”。
e.g. Energy can move things. (只能用can)
can和be able to比较
