Generations of grammarians and schoolteachers have insisted thatcan should be used only to express the capacity to do something, and thatmay must be used to express permission. Technically, correct usage therefore requires
好幾代的語法學(xué)家們和中學(xué)教師們主張can 只應(yīng)用于表示做某事的能力， 同時may 必須用于表示許可。 因此，在學(xué)術(shù)上糾正其用法要求

The supervisor said that anyone who wants an extra day off may (not can ) have one, or
管理人說任何想要一日特別休假的人都可以得到（不是 can ） 一天， 或者

例句：
May (not can ) I take another week to submit the applicationô
我可以（不是 can ） 再花一周提交申請嗎？

Only 2 percent of the Usage Panel acceptscan in the latter sentence. Butcan has a long history of use by educated speakers to express permission, particularly in British English.What is more, the blurring of the line betweencan and may is socially and historically inevitable, since politeness often makes the use ofcan preferable in the .permission. sense. For example, the sentenceYou can borrow my car if you like is a more gracious offer than You may borrow my car; the first presumes the granting of permission,while the second makes a point of it.Still, it is understandable that insistence on the use ofmay should become a traditional schoolroom ritual, particularly in first-person requests such as
用法專題使用小組中只有2%的成員接納can 用于后面一句中。 但can 被受過教育的說話者用于表示許可已有很長的歷史， 尤其是在大不列顛英語中。而且，can 和 may 之間不明顯的界限從社會和歷史淵源上說也是不可避免的， 因為禮貌常使can 的使用比較適宜.允許.這個意義。 例如，句子如你想要的話，你可以借用我的車 是比 你可以借用我的車； 親切得多的提議， 第一句假定表示許可，而第二句卻限定于這一點。然而，主張may 的用法應(yīng)成為課堂內(nèi)的慣例也是可以理解的， 尤其是在第一人稱中，如
例句：
May I leave the roomô
我可以離開這屋嗎？

since it requires the pupil to distinguish explicitly between what is possible and what is allowed,a difference not always apparent to younger children.And even in later life,observance of the distinction is often advisable in the interests of clarity.Thus, the sentenceStudents can take no more than three courses allows the possibility that a student who is unusually capable may take more, whereasStudents may take no more than three courses does not. · The use ofcan to express permission is better tolerated in negative questions, as inCan`t I have the car tonightô probably because the alternative contractionmayn`t is felt to be awkward.
由于這要求學(xué)生清楚地區(qū)分可能的和得到許可的兩者之間的差異，而這對小孩子們常常是不太明顯的。并且在其今后的生活中，為明確起見，體會這種差異常常是很可取的。因此，句子學(xué)生們可以選修不超過三門的課程 給能力超常的學(xué)生學(xué)更多的課程提供了可能性， 然而學(xué)生們只能選修不超過三門的課程 則不能提供這種可能性。 can 的用法更可用于否定疑問句中表示許可， 如 我今晚不能使用這車嗎？ ， 或許是由于可替代的縮寫mayn`t 感覺起來有些笨拙的緣故
