Dear Caroline,

I am Li Hua, director of an English program named “Talk and Talk” in our school radio station. It’s a complete privilege for me to invite you to give an interview for the show. Please allow me to elaborate on the details.

“Talk and Talk” is a weekly one-hour live program, which enjoys greatest popularity among the students. This show embraces a wide range of issues, such as English learning methods, hot topics around the world, and new things in our school. The theme of next week’s program, which we cordially invite you to take part in, is “How to learn English beyond the classroom”. Apparently, this topic is of vital importance for our students. Therefore, I, on behalf of the whole radio station, sincerely hope that you could take this interview at 6:30 p.m. next Friday.

Again, your presence will be highly appreciated, and we are really looking forward to your positive reply. 

Yours sincerely,
Li Hua
