Dear Professor Smith,
It's my pleasure to plan the theme of the debate on city traffic.
I am writing this letter to put forward suggestions on a specific topic
and introduce mypreliminary arrangements concerned.
Firstly,the debate can be conducted with the topic of "ofo'or not"on the ground
that people divide opinions on the efforts of public transport made bysharing economy.
In addition,
the debate could be held next Sunday afternoon in the seminar hall on our campus.
Finally,rewards should be prepared in advance for the winner of the debate.
Please feel free to contact me in your convenience if you have other ideas
about the topic and arrangements.I am looking forward to your early reply.
Yours sincerely,
Li Ming
