Dear Mr. Green,
I'm very exciting to learn that you will start a magazine together. That sounds great and I definitely agree you on that.
Some of the columns that you mention in the letter are really my cup of tea. "Cultural Express" give us a better understanding of the world. Since people from different part of the world have different values, it's necessary to learn from each another. Apart from that, "Blurt Out" is pretty good for Chinese students to learn English idioms and improving oral English. "Entertainment" is also cool! The popular singers, actors or celebrities are so attractively that you absolutely can't miss this part. Teenagers are to fond of popular things, too.
Well, I can't list more. I really can't wait to read this magazine.
Yours,
Li Ming
