【答案解析】范文 Dear Sir, There is probably a good reason why you haven't completed our order for photographic paper and chemicals. You acknowledged our order on 20th May, however, we have not yet received the order or any news regarding it, and wonder if it has since been overlooked. We have two masons for wanting the material ordered. Obviously, we want to apply them to the present urgent work. But just as important, we want you feel free to resell. By completing the order now, you will allow us to continue placing the orders you need, as you need them. That will help your sales and ours. The delay in delivery is now causing numberous inconvenience. Without the immediate delivery, we shall be obliged to cancel and obtain the materials elsewhere. Yours faithfully, International Trade Corporation
