    至此網址你可學到shoul/would/could/may這些情態助動詞的用法,例如

    Could的用法:

    A. can 和 could 都可以用來「請求允許」,但 could 比較有禮貌、比較客氣:

    (註:may/might 也是用來「請求允許」,但一般認知,may/might 比 can/could 要來得正式,也就是說,在向關係比較生疏的人,或是長輩等「請求允許」時,用 may/might 比較合適些。)

    例:

    5. 我可以問你一個有關 Mike 的問題嗎?

     Can I ask you a question about Mike?

     Could I ask you a question about Mike?(用 could 比較有禮貌、比較客氣)

     上述兩句的回答句,不管是「肯定回答」、還是「否定回答」,都只能用 can

    參考上面的解釋,你該得到答案了吧!

    另外,建議你也學好"假設語氣"(subjunctive mood)的用法,這與上述情態助動詞的用法有些關係.

    你或許疑惑為何要用could, 這或許是因為是一種與現在事實相反的情態吧.

    依據假設語氣的規則助動詞就要用過去式,例如:

    I wish if I could. 但願我能(與現在事實相反--就是我現在不能,我才會這麼說)

    總而言之,用could是比較禮貌的問法(一種假設性的/不那麼肯定的問法),這已經成為老外的習慣:

    Could you do me a favor?

    希望有幫到你

    當然可以,意思一樣。只是用could比can 在口氣上較客氣。
