Last Sunday, I did housework with my mother at home.
上周六，我在家帮妈妈做了些家务。
My duty was cleaning my bedroom and sorting the bookshelf.
我的任务是打扫我的房间以及把书架上的书分类。
After breakfast, I started my work. I first arranged books on the shelf.
早餐过后，我开始了我的工作。我先排列了书架上的书。
Previously, most books were my textbooks, but I wanted to do some changes.
显然，我大部分的书都是教科书，但是我想稍作改变。

I picked up the textbooks on a cartoon and put the books I read at spare time on the shelf.
我把课本放到卡通一栏，然后把我课余时间看的书放到书架上。
And then I started to clean my bedroom. Because mother cleaned it almost everyday, so my task was not so heavy.
接着我就开始打扫我的房间。因为妈妈几乎每天都打扫，所以我的任务不是很重。
After I finished my own duty, I helped mother with other works. Before lunch, we finished all the housework.
我完成我的任务后，我就帮妈妈干其他活。吃午饭前我们就做完了所有家务。
