題號	答案	一句解說
1	Could you please tell me the price?	Can you 較口語，正式電郵用 Could you please 較有禮貌。
2	Yours sincerely	知道收件人姓名時用 Yours sincerely，完全不識名才用 Yours faithfully。
3	the date comes first	英文書信日期寫在稱謂之上，先寫日期才寫 Dear。
4	to apply for a summer course	「I am writing to apply for…」一句直接點出申請目的。
5	I paid $80 on 3 May and the receipt is attached.	證據要具體：金額、日期、單據，對方才跟進得到。
6	$4 320	24 位學生每人 180 元，180 乘 24 得 4 320 元。
7	what went wrong, an apology and what you will do	道歉信三部分：發生何事、道歉、補救行動，缺一就顯得推卸。
8	the date, the time and the place	邀請信要清楚日期、時間、地點，收件人才能回覆。
9	a very polite formal request	「I would be grateful if…」屬高禮貌程度，適用於向機構請求。
10	Because an unnamed reader takes Yours faithfully	Dear Sir or Madam 屬不知名收件人，結語必須配 Yours faithfully。
