—Could you swim at the age of 5 ? ——No,I____
(选项略)
这是英语周报上的一道题,它的答案是 couldn’t .
但我曾经在另一本教辅上看过这样一个语法点:在问句中,could比can语气更委婉,但无论在肯还是否定句中,其答句都不能用could,而要用can.
请问如何理解?哪个说法是正确的?

请问如何理解?哪个说法是正确的?
其实,你所说的“委婉”用法,是could 用于一般现在时,表示请求或征询意见.
而can 还可表示能力,could 表示过去的能力.此句的意思是“你五岁的时候会游泳吗?”,表示能力,不表示委婉.
could的用法:
1.“能;会”,表示过去的能力.如 He could write when he was five years old.
2.“可以”,表示过去的许可.如 She said we couldn’t get into the room.
3.“能”,表示请求或征询意见,比can更委婉.如 Could you help me with English every day?答语常不用could,而要说成:Yes,I can./ Sure./ Certainly./ Of course./ All right./ OK./ I’m sorry…等.
4.“可能”,表示推测,用于肯定、疑问或否定句中均可.
○1表示对过去的推测.如 He said he couldn’t help her again.
○2表示对现在、将来的推测,但把握性比can小.如 – Where’s Bob?– I’m not sure.He could fight with others again.
