Dear Mr. Green,

I’m very exciting to learn that we will start a magazine together. That sounds great, and I definitely agree you on that.

Some of the columns what you mentioned in the letter are really my cup of tea. “Cultural Express” gives us a better understanding of the world. Since the people from different parts of the world have different values, it’s necessary to learn from each others. This will offer a wonderful chance. Apart from that, “Blurt Out” is pretty good for Chinese student to learn English idioms and improving oral English. Last but not least, “Entertainment” is so cool! The popular singers, actors or celebrities are so attractively that you absolutely can’t miss this part. Teenagers were just fond of popular things.

Well, I can’t list more. I really can’t wait to read this magazine.

Yours faithfully

Li Hua
