三、语法知识点
情态动词could的用法
【1】表示过去的能力，有时可用could，有时不能用could，具体应注意以下几点：
① 若表示过去一般的能力(即想做某事就随时可做某事的能力)，可用could：
② 若表示过去的特定能力(即在过去特定场合做某事的能力)，则不能用could，而用was (were) able to do sth。
【2】表示请求及许可
(1) 对于现在或将来的“许可”，要区分以下两种情况：
① 表示请求允许(即请求别人允许自己做某事)，两者均可用，但用could语气更委婉：
② 表示给予允许(即自己允许别人做某事),一般只用 can，而不用 could：
【3】Could you please do sth 请你（做）......好吗？
用于提出请求，希望得到对方的肯定回答，说话的语气比较客气委婉。
Could 不是can的过去式，是委婉、礼貌的说法。回答用can.
【常用答语】肯定回答：Sure./ Of course./ Certainly./No problem./I’d like to…
否定回答： Sorry , I can’t/I’d like to, but…/sorry, but I have to…
