写完老师布置的作业，我发现我的书包脏的几乎看不出原来的颜色，所以决定自己动手刷书包。
After finishing the homework assigned by the teacher, I found that my schoolbag was dirty and could hardly see the original color, so I decided to brush my schoolbag by myself.
我在大水盆里放上一定量的水，先让脏兮兮的书包躺在水里浸泡十分钟。然后我再往水里加上两小勺洗衣粉，拿起毛刷，对准书包上最脏的部分，用力来回刷，洗刷刷，洗刷刷刷完书包最脏的部分，然后再刷其他的地方，二十分过去了，我累得满头大汗，又用清水冲刷三遍，书包就露出来了庐山真面目五颜六色的。
I put a certain amount of water in the big basin, and let the dirty schoolbag lie in the water for ten minutes. Then I add two spoonfuls of washing powder to the water, pick up the brush, aim at the dirtiest part of the bag, brush back and forth vigorously, wash, wash... Brush the dirtiest part of the bag, and then brush other places. Twenty minutes later, I was so tired that I sweated all over my head and washed it with clear water three times. Then the bag revealed the true face of Lushan Mountain - colorful
我仅仅刷了一次书包，就累得这样，我忽然明白了，妈妈既要上班，又要干家务，肯定比我还要累，只是妈妈不愿明说了，以后，我要更加讲卫生，不要让衣服和书包脏的那么快，减轻妈妈干家务的负担。
I just brushed my schoolbag once, and I was so tired. I suddenly understood that my mother must be more tired than me, not only to go to work, but also to do housework. But my mother would not say clearly. In the future, I would like to be more hygienic, not to make clothes and schoolbag dirty so fast, and reduce the burden of my mothers family work.
