一个晚上,我和妹妹去院子里荡秋千。我看到保洁工人拖着环保车,拿着扫把,一下一下十分专注的、艰难的扫着地上的落叶和垃圾。我想:环保工作每天都要扫几十次的垃圾,还拖着重重的环保车走来走去的,多累啊!要是有更方便的方法能清理垃圾就好了。 One night, my sister and I went to the yard to swing. I saw the cleaning workers dragging the green car, holding the broom, look very focused, difficult to sweep the leaves and garbage on the ground. I think: environmental protection work dozens of times a day to sweep the trash, but also dragging a heavy green car walking, tired! If more convenient way to clean up the garbage just fine.
