我写邮件~都发给超级顶级的老板们~~突然就不知道该怎么写好了~~~

主要是说这个报告可以让你们知道我们正在做什么，进展的怎么样~~

一楼的谢谢，可是有点不太温和，能不能在activity上发挥呢？

你写得挺好的。语气很适当。
你只要加个dedicating就可以了，表示我们正在尽力、致力、玩命的意思。

Dear sirs,

Attached you can find the report, this will keep you informed the activities we are dedicating.

This report will be sent o you time by time.

Dear sir

谢谢befriends01，我就是比较犹豫activities后面用什么~
dedicating有点严重了，我在想用working on还是under process还是其他的什么~~
