　　In North America, most students go to school by bus．The subway is also widely used in some cities．In small towns and cities, walking is still popular．

　　The yellow school bus is a familiar sight all over North America．It is a very convenient (方便的) form of transportation (运输)because it takes students right to the entrance(人口)to the school．It also gives students opportunity (机会)to chat with their friends．However, the bus is slow and does not always pick up on time．

　　The subway is a means of getting around quickly in many cities．However, it is expensive(贵的)and can be very crowded during rush hour(高峰时间)．Another disadvantage of the subway is that the stops are not so close to the school, and students often have to walk considerable distance or take a bus from the subway stop to the school．

　　Walking has a number of advantages (优点)for those who live reasonable close to school．It's free and it provides(提供)a form of exercise．However, it's no fun if you have a large backpack full of books to carry．It's also unpleasant if the weather is either too hot or too cold or wet．
