     John is thirteen now. He began to study in a middle school two years ago. His home is in a small village

and it's nearly five kilometers from the school. He has to get up early in the morning. After a quick breakfast

he has to run to school and get there on time. His father hopes to borrow some money to buy a bike for him,

but he knows his mother is always ill and his father spends much money on medicine. He doesn't agree with

his father and keeps running there every day. Now he's very strong. He is never late for class and his teachers

often praise him.
