How much pocket money do you get from your parents every month--200 yuan? Some may need more to buy birthday presents, fast food lunches, ice cream or cartoon   books. But for Zhou Li, 30 yuan a month is enough. The only thing she buys is lunch--1.5 yuan each day. "My favorite is fried potato slices and rice," said Zhou, "meat is too expensive for me." Zhou, 14, is a Junior 1 student at Hongzhi Experimental School in Beijing. Her parents are migrant workers  . They came to Beijing from a village in Luohe of Henan two years ago. Her father now works as a cleaner and earns 500   yuan every month. Her mother has no job. Every day, Zhou gets up at 5: 30 a.m. and rides 20 minutes to school. She studies hard, and even reads books during breaktime. Her favorite subject is computer."I'm learning typing now. I hope to be the fastest in my class."said Zhou. Like many teens, Zhou has a lot of homework. It usually takes her at least one hour to do it every day. But that is not all her work. She helps her mom cook. On weekends, she helps wash clothes."I could cook when I was eight. Father said sometimes I cooked better than mom!" Zhou said she wanted to be a doctor when she grew up."I watched TV and found that there were many people with AIDS in Henan. Some are kids. They need help."said Zhou. But she is afraid of having to leave school."I hope I will always be in school," said Zhou. "Dad works hard to make money. I promise him I will study hard to be a good student at present and a good doctor in the future." Zhou Li spends   _   on her homework every day.
