“汽车尾气对地球的危害非常大……”思想品德课上,老师又在给我们讲低碳生活了。汽车尾气?我一下子想到了自己。每天,妈妈都用私家车送我上学,接我回家,1天至少要消耗2升汽油,还会排放出大量的尾气。现在,我已经上五年级了,5年,1000多天,得排放出多少尾气呀! “Automobile exhaust on the hazards of the Earth is very large ... ” Ideology and morality class, the teacher told us about low-carbon life again. Car exhaust? I suddenly thought of myself. Every day, my mother used a private car to send me to school and took me home. At least 2 liters of gasoline were consumed in one day and a large amount of exhaust gas was emitted. Now, I have the fifth grade, and five years, more than 1,000 days, how much exhaust emissions have!
