单选题
In which of the following ways of booking docs one probably have to pay extra money?
【正确答案】
D
【答案解析】[精解] 文章理解题。逐一查读选项中订票四种方式,马上可以找到在BY POST标题下有这样一句:"Please enclose a cheque or credit card details together with an SAE or add 50p to the total amount to cover postage.",句子意思为:……另外在总金额加上50便士支付邮资……。因此[D]为正确选项。
