阅读短文，回答问题。 I am Lisa, I study in Beijing International School now. There are fifty-four students in my class. Only six students go to school on foot, because they live near our school. Li Xiang says it usually takes him about fifteen minutes to walk to school. Eighteen students go to school by bike. Some of them think it i s faster to ride bikes than to take buses in the morning and evening. They also think riding bikes is good for them. Twenty-two students take buses or the subway to school. Most of them have to take more than one bus to get to school, so they must get up early every day. And other students go to school by car. Their parents drive them to school first, and then go to work. Do you know how I get to school? I'm one of the eighteen people. 1.
