【答案】Dear Mr.White，
I am Li Hua.Chairman of Shudents' Union of Hongxing High school.We are disappointed and particularly sorry to tell you that the lecture scheduled for next Wednesday afternoon cannot take place as planned，due to concerns over the ongoing developments of the COVID-19 epidemic.I am writing to consult you about a workable solution.
To safeguard the health of everyone involved，we have two alternative plans in mind.We can switch to on-line conferencing platform so that we will still be able to listen to your much-anticipated lecture next Wednesday.Or we can reschedule the lecture for a later date until further notice.Could you please tell us which option suits you best？
We regret any inconvenience caused and look forward to your reply.
Yours，
Li Hua
