Dear Mr/Ms,

　　Last Friday, when we were discussing the problems of defective containers.You suggested that I simply mail you a report each month on the number of return by customers rather than send the defective containers to you.

　　I plan to put this into effect at once. But, I first want to make sure that I understand you correctly. If I don’t hear from you within the coming week, I’ll assume that you approve.

　　Yours faithfully

　　尊敬的先生/小姐：

　　上周五，我们讨论了次品集装箱的问题，你建议我只需把顾客每月退回的次品集装箱的数量写个报告给你，而不是直接退集装箱。

　　我计划立即付诸现实。但我想确认我理解正确，到下周为止，如我不能收到你的来信，我即认为你没有异议。

　　你诚挚的
