My best friend is one of my classmates. We have the hobby. We both enjoy music. I am good English, but she isn’t. She has great interest in university (大学) life and wants to go to university when she school. One day, I found her studying so I wanted to help her with it. she closed (关上) the book. I asked, "What are you doing?" "Nothing," she answered shyly. I didn’t know she closed her book. "I just want to you," I said. "Please don’t laugh at me. My English is not good and I’m a little about learning it in front of others." " laughs at you. That’s why you don’t make any progress (进步) in English. You should try. You should do your best to English with your friends. You can also ask for help from them."
