✔ 最佳答案
might (用於表示可能性很小) (代替may 在問句中作禮貌用語)
may (used to show possibility)可能,也許
用法說明
(1)談論到可能性的時候,might 有時會暗示比 may 的可能性更小,但這兩個詞經常用於表示同樣的意思:
I may/might see you tonight; I do not know yet.
(我今晚可能來看你,但目前還不敢肯定。)
(2) There can be a difference between
He may have (=perhaps he has) drowned, and
He might have drowned (=he was in danger of drowning, but he did not).
上舉兩例是有區別的,前者作「他也許已經淹死了」解,後者則作「他差點淹死了」。但現在很多人用這兩個詞表示同樣的意思。
could (用於表示可能性而不是肯定無疑)
用法說明
could (過去式 could have)像may 和 might (過去式 may have 和 might
have) 一樣用於表示「也許」(不肯定),但並不常見:
He may/might/could be on his way now.
(他現在可能在路上了。)
He may/might/could have been delayed.
(他也許被耽擱了。)
