I learned with great regret that you are leaving Dell soon.I am grateful to you for offering me the opportunity to work at Dell.And I also wish you the best of luck in the new company.All the best to ...第一句好像不对，是十分遗憾的知道你将要离开DELL公司啊！第一句是对的，因为看似现在是的You are leaving或You are going在英文里是表示将来是用的。当然，更好的表达方式是I learned with great regret that you would be leaving Dell soon.另一种非常正式的说法是：It was with great regret that I learned you would be leaving Dell soon. 我的学生的学生的学生的学生，都在教比这类内容深得多的东西。你就放心好了。顺便提一下，我还多次见过你们公司大老板和比尔盖茨呢。楼上有两句倒是错的。你知道是哪两句吗？还真不知道那2句错的，还请告知啦~~~我都没见过盖茨！羡慕你！错处：having provided with the opportunity for me to work in Dell Wish everything will be OK with you （跟奥运村村长欢迎词的翻译错误异曲同工）
