Dear Mr Li,
Thank you for your letter of Feb. 16. We are interested in your new type of recorder, AW----501. We plan to buy 10 sets of this type. But the price seems a little high. We wonder if  you could cut down the price to ￥530 for each. If so, we would go and visit you on Feb. 26. Is the date suitable for you? Please reply as soon as possible.
                                                                                                                         Yours truly,
                                                                                                                           Zhang Ying
【写法指要】
1）尽管这两封信均没有信内地址，但信头却都很齐全，属于事务书信。特别正式的事务书信要求把信头和信内地址都写全，一般事务书信可以不写信内地址。
2）事务书信是公司与公司，公司与机关团体，公司或机关团体对个人写的书信，属于正式的信件往来，所以要用正式文体来写。信文里不能出现缩约形式。
3）写英语事务书信时要开门见山，一开始就接触主题内容，不能迂回。回信更应直接了当地就来信中的内容答复对方。
