I have a good friend in my class. His name is Jack Green. He is twelve, and I am twelve, too. His father and mother work in Beijing. He likes Chinese food(食物) very much. I often ask him to my home to have Chinese food. "Welcome to our house."My father says to Jack. "And thanks for helping my son Wang Lin"
"You're welcome. I'm English. I can help him with his English. And he can help me with my Chinese. We help each other(互相)."
