Directions: There is a business letter below. After reading it, you should give brief answers to the 5 questions (No. 56 through No. 60) that follow. The answers (in no more than 3 words 答案不超过三个单词 ) should be written after corresponding numbers on the Answer Sheet. Dear sir, We are pleased to receive your inquiry of 10 th January and enclose our illustrated catalog and price list giving the details you asked for. We are also sending you by separate post some samples and feel confident that when you have examined them you will agree that the goods are both excellent in quality and reasonable in price. We can offer you the same discount facility offered to all our customers—5% discount on orders over $1,000. Payment has to be made no later than 20days after receipt of invoice, and late payment is subject to interest, and all discounts become void. Because they are soft and durable, our cotton bed sheets and pillowcases are rapidly becoming popular, and after studying our prices you will not be surprised to learn that we are finding it difficult to meet the demand. But if you place your order not later than the end of his month, we would ensure prompt shipment. We look forward to your early reply. Sincerely, Wang Ling
