qiangqiang is my classmate. he is nine years old. he doesn't study hard. he talks a lot in class, so the teacher is often angry with him. he doesn't like to do his homework, but he likes sports. he plays football very well. in fact, he is the best player in our class.

　　qiangqiang's father has a clock, and it is very nice. it sings in the morning to wake up qiangqiang. "what sings in the clock?" one day he wondered. so he opened the clock and took it to parts.
