My name is Joe. I'm a student in No. 3 Middle School. I have a brother and a sister. They are Tony and Mary. We are in different(不同的) schools. Every morning, we get up at half past six. At seven o'clock，we have breakfast with our parents. Then we go to school. Tony's school is about two kilometers from our home. So he goes to school by bike. He thinks it's healthy. He needs about ten minutes to get to school. Mary is in No.6 Middle School. How does she go to school? She takes a bus first. Then she has to take the subway. It takes her forty minutes to get to school every day.

I usually walk to school because my school is only about one kilometer from my home. I need about ten minutes to get to school. So I'm never late for school.
