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.
我喜歡騎自行車上學,因為我可以通過騎車保持健康。北京依然流行自行車,一些外國人也買自行車騎。但是越來越多的人買汽車,因為他們認為汽車比自行車快。汽車的尾氣污染了空氣,浪費了能源。我認為自行車比汽車好。
