Dear Dr. Brown,

Thank you so much for having been our consultant for such a long time. With your guidance, our broadcast station has been making great progress and is very popular with the students.

In order to celebrate the 10th anniversary of our station, a celebration will be held in the school lecture hall at 7:30 next Friday evening. In the celebration, there will be some performances such as singing and dancing, and we can also play games.

We would like to invite you to give a speech at the celebration. We would appreciate it if you can spare the time to come.

I am looking forward to your reply.

Yours,
