my house I don't have many rules. I can go out   3   school nights, but I need to go home   4   ten o'clock.
I like   5    the drums. It's really noisy (充满噪音的) when I play them, but Mom doesn't   6   it. She thinks
it's OK. I have a computer in my room. I do my homework on my computer. I like playing computer games, and I often play them when I finish (完成) my homework. "Homework comes first," Mom   7   says to me.
I can sleep   8   on weekends and I enjoy   9   books in bed on weekend mornings. On Saturday afternoon, I usually clean my bedroom. Mom cleans the other rooms, but I often   10   her. On Sunday afternoons, I
go to the music club and play the drums with my friends. It's fun.
