开发维护篇（12）：再次寻求业务合作
Dear Mr. Johnson,
亲爱的强森先生：
Since our last conversation, two year has passed.
自从上次的联系后，两年已经过去了。
We very much regret we lost our last trade opportunity, but we are so happy that we still have an opportunity ahead of us now. We have been extending the scope of our products in the past years. I am sure some items would be of great interest to you. The catalogue and all necessary information for your reference are enclosed.
尽管我们对上次不能合作而感到深深的遗憾，但是，我们现在仍然很高兴，有了新的机会。过去的几年中，我们一直在扩大产品范围。相信一些产品将会让您颇感兴趣。随函附上目录和有关资料，供您参考。
Looking forward to hearing from you.
期待您的回复！
Yours sincerely,
Chris Ellen
