Unit 1 Can you play the guitar【刷语法】(重点语法提升练)
情态动词can
1、结构:can + 动词原形,没有人称和数的变化。
2、否定形式:cannot/can’ t, cannot比缩略形式can’ t要正式。口语中一般用缩略形式。
例如:I can swim.
Daming can ride a bike. He can’t drive a car.
二、用法
1、 表示能力(体力、知识、技能等),此时可用be able to代替。
例如:Mary can speak three languages. 玛丽会说三种语言。
= Mary is able to speak three languages.
注意:(1)can只有一般现在时和一般过去式;而be able to则有更多的时态。
例如:I’ll not be able to come this afternoon. 今天下午我将会来。
(2)当表示“经过努力才得以做成功某事”时应用be able to,不能用can。
例如:He was able to go to the party yesterday evening in spite of the heavy rain. 尽管很大雨,他昨天能来参加聚会。
2、表示请求和允许。
例如:---Can I go now?
--- Yes, you can. / No, you cannot/can’t.
此时可与may互换。在疑问句中还可用could,might(不可用于肯定句、否定句或答语)代替,不是过去式,只是语气更委婉。
例如:--- Could I come to see you tomorrow?
--- Yes, you can. ( No, I’m afraid not. )
3、表示可能性猜测。
例如:The man over there can′t be my uncle. My uncle has gone to Beijing. 那个人不可能是我的叔叔。我的叔叔去北京了。
