Dear all,

Just want to let you know that for the whole of the MRI, you did a great job as a team on Friday dealing with the problem of the virus. Thank you all for your concerted effort.

Analysis

前三封是比较正式的感谢信。每封信都由三部分组成。每封信的开头先向对方表示感谢，进而具体说明感谢的事由，结尾再次感谢对方。措辞真切、态度诚恳。第四封信内容非常简单，属于非正式的感谢信：先认可全体员工的出色表现，再向大家表示衷心感谢。在公司内部常常会用这种写作风格简要表达感谢。
