Dear Peter,
How are you doing there in Britain during this pandemic? After careful consideration of the current global conditions, we regret greatly to suggest cancelling this summer's mutual visits of our graduates.(提议取消活动)
I'm sure we're on the same page that it will be a sensible decision to make due to increasing concern over the health and safety of our students. As is reported, the virus is still spreading and the number of cases is on the rise worldwide. 【高分句型一】Thus it is with deep regret that we may be unable to see each other in the coming summer.【高分句型二】 It is our greatest hope, though, that our visits will be rescheduled under safer circumstances.(说明原因)
Let's stay in close contact and do take care of yourself during this emergency period!(表达遗憾与希望)
Yours,
