問：要說學生不喜歡老師「高高在上」、「黑口黑面」，英文怎麼說？「黑口黑面」可不可以譯做serious？
答：英文superior一字，除了解作「較好」，也可帶貶義，指「自覺高人一等」，例如：He always puts on his superior
manner in front of his students（他在學生面前，總是擺出高高在上的神氣）。
Serious是「嚴肅」或「莊重」，和「黑口黑面」（一臉不高興神情）不同。《牛津高階英漢雙解詞典》scowl條下的解釋和例句是：「an angry look or expression不悅的神色：He
looked up at me with a scowl他臉色陰沉，擡眼看了看我。」這scowl就是「黑口黑面」。我們可以說：Students do not like a teacher who always
wears a scowl on his face and carries a superior air（學生不喜歡教師整天黑口黑面，一副高高在上神氣）。
問：要說「申請表格須附出生證明書和大學畢業證書副本各一份」，以下英文說法哪個正確？──Applicants should attach to
their application forms a copy of / copies of their birth certificates and
graduation certificates。」
答：副本既然只要一份，那麼，不管原件多少，copy都應用單數形式，不用複數。不過，讀者示下那一句，最好像中文有「各」字一樣，加each一字，意思會更加清楚：Applicants should attach to their application
forms a copy each of their birth certificates and graduation certificates。假如副本要兩份，那才用複數形式的two copies。
