Dear Mr. Liu.
I have a friend named Mark Baker, who is now teaching history in Washington University. He was born in New York in April, 1968. He began his study in Julliard Primary School in 1974 and graduated from Sidewall Friends Secondary School in 1986. Then he entered Columbia University, where he studied for more than six years and got the doctor’s degree of history. Meanwhile, he studied Chinese as his second language. He has good experience in teaching and his health is in good condition.（英语作文）
He has always dreamt of coming to China to teach Chinese students. He would be most grateful if you would give him the chance.
Looking forward to hearin.
