【答案解析】ABC Engineering Company Office Supplies Company 77 An Nei Jie, Wuhan 222 Nathan Road 28th January Dear Li Wei, I am pleased that you are interested in our new fax machines. The new fax machine is multi-functional. It can be used as a telephone and it can send signals down an ordianary telephone line to another fax machine. When you put a sheet of paper in a fax machine, the machine "reads" the writing on the page and sends it out to another fax machine. It is much quicker than posting a letter and much cheaper than making a phone call. Fax machine pricesvary with different brands. A Samsung is cheaper than a Sony or Panasonic. Of course the price depends on the quality of the machine. Some of our fax machines are both of high quality and reasonable price. An average fax machine costs about 1, 800 yuan. We can arrange for a salesman to go and discuss business machines at your request. Looking forward to your answer. Sincerely, Li Ming Sales Manger
