求一位英语高手帮我写一篇英语作文!

Dear Susan, I'm glad to learn that you will come to Beijing to compete in a speech contest of foreign middle student .It is my pleasure to offer you help in your speech contest .
Now let me tell you something important when you start your speech. First of all,it is quite important to learn some Chinese culture ,such as Chinese food and Chinese art.In this way ,the listeners you are faced with will have a good impression on you. Then, be natural when you give your speech .Also,you can use some body language if possible. It helps a lot. At last, wish you success.I believe you can do it well !
Yours,
Li Hua
