One night, I 小题1: (listen) to music in my room when there was a knock on the door, then I heard a voice “Would you mind my 小题2: (come) in?”I turned down the CD player. Then I said,“Come in, please!”It was my friend Tony. There  was a book in his hand. He came to my home to return  my book. He also brought me a poster. It said there was a big clothing sale in a shop. He asked me if I would like 小题3: (buy) one. I told him I didn’t like  new clothes at all. Perhaps it was not polite 小题4: _ __(say) no to him. Then he left my room right away. But I wasn’t annoyed.
