这几天,天气慢慢变冷。每天早晨上学坐在车里,开着暖气,还嫌不暖和。透过窗玻璃,常常看到一辆围板上写着“垃圾”两字的电动三轮车从我们车旁驶过,里面坐着几个跟我年龄相仿的小朋友。咦,垃圾车里怎么有学生?我百思不得其解。我请求妈妈放慢车速,紧跟着这辆与众不同的垃圾车。 These days, the weather is getting colder Sitting in the car every morning go to school, driving a warm, still not warm. Through the window glass, I often saw an electric tricycle with “garbage ” on the wall passing by our car and sitting inside with a few children of my age.咦, how to have garbage in the car? I baffled. I asked my mom to slow down and follow this unusual Garbage Truck.
