Dear David,

I am Lihua, a senior high school students. I have recently learnt on the Internet what you are helping students with spoken English by offer an online course. I am writing to ask you for some help.

I have been learnt English for more than four years and I really like English. However, my spoken English is such poor that I can not communicate with foreigners free. My broken English always discourages you from opening my mouth. I am really worrying. I hope you can help me with my spoken English. I believe that I can make a progress with your help.

I would appreciate it if you could agree help me. I am looking forward to your reply.

Sincerely,

Lihua
