I like going to school by like, because I think I can keep healthy by riding.Bicycles are still popular in Beijing. Some foreigners buy bicycles to ride.But more and more people buy cars because they think they are faster than bicycles.In fact the exhaust gas from cars makes the air dirty and they waste energy.I think bicycles are better than cars.

我喜欢骑自行车上学，因为我可以通过骑车保持健康。自行车在北京依然很流行，一些外国人也买自行车骑。但是越来越多的人买汽车，因为他们认为汽车比自行车快。汽车的尾气污染了空气，浪费了能源。我认为自行车比汽车好。
