Dear Mr. Smith,
Our school MUN is going to hold the fifth Model United Nations on November 10 and 11 in Meeting Rooms One, Two and Three. The theme is global climate. We sincerely invite you to be one of the advisors.
There are some new members in MUN, and the process, how to prepare for MUN and how to write the position paper, etc. are too complicated for them. Therefore, advisors are needed to train them. Besides, in order to improve their English, some teams are determined to use English as their work language. How to express themselves properly and correctly and correctly in oral or written English is a problem. So we are in great need of native English speakers as our advisors. I know you are a MUN lover. Do come and join us.
Yours sincerely,
