请求篇（9）：请求延期
Dear Mr. Harding,
亲爱的哈丁先生：
I am terribly sorry for the overdue balance on our account. It turns out that the last invoice we received from you was somehow misplaced. Would it be possible to grant us a 5-day payment extension? I can ensure that you will receive the outstanding balance by next Thursday.
非常抱歉我们逾期未能付清账款。原来是上次您的发票寄来之后不知怎么找不到了。我想问一下可不可以再延长五天的支付期限呢？我保证下周四之前您可以收到未付账款。
I appreciate it very much for your understanding.
非常感谢您的谅解。
Yours faithfully,
Catherine Jones
