【正确答案】正确答案：Dear Sir or Madam, I sent you on July 12 an order for woolen sweater to the value of US $ 25,0000 and impressed upon you the necessity of delivery within 15 days from the date of order. In spite of this, 20 days have elapsed from that date, but the goods still haven't reached us. We must point out to you that this delay is very seriously inconveniencing us; our present stock of these goods is exhausted, and we are unable to meet our customers' demands, who in consequence, have in many cases placed their orders elsewhere. We should be glad to hear from you the reason of the non-execution of our order, as in the event of your being unable to supply us we shall be compelled to cancel the order and get these goods from another firm. Yours truly, Alan Colson Account Manager
