can与could引导问句回答

1、can 表示现在的能力,could 表示过去的能力,例如:He can speak a little English now. She could play the piano when she was five. 2、在表示请求许可时,没有时间区别,在语气上could 更加委婉客气,例如: Can I use your pen ? Could I

1.could 引导的 一般疑问句如果是表示客气语气的句子,用Yes, I can.回答.Could you tell me how to get to Yes,I can./Of course,I can.2.could 引导的 一般疑问句如果是表示过去的能力就用could 回答.Could you swim when you were ten years old? Yes,I could./No,I couldn't.

could如果是表示“可能”用于一般过去时态时,回答可用could.e.g.Could he play the piano two years ago?肯定回答:Yes,he could.否定回答:No,he couldn't.如果表示“委婉”,回答用＂can＂.e.g.Could I use your comp

用cancould引导问句,表示一种礼貌,婉转的请求,但回答需坚决

would引导的一般疑问句肯定回答怎么说1-如果是would you like?肯定:yes,i'd love to.否定:no, thanks./ i'd like to, but2-其他would+主语+动词原形?肯定:yes, 主语(代词)+would.否定:no, 主语(代词)+wouldn't.

你好,都用could't是肯定不会错的,因为could可以是礼貌用词也可以是can的过去式.如果想要区分开来用,那就要根据问题提问的内容了.如果问句提问过去的内容,就用could'd;如果问句问的是一般现在式,就用can't

不用,这一般表示尊敬的意思,才用could

could?好像是yes u can. No u couldn't 吗??我只记得must need 和 may的用法了

yes(no),i could(couldn`t)
