Last Sunday, I did housework with my mother at home.My duty was cleaning my bedroom and sorting the bookshelf.After breakfast, I started my work.I first arranged books on the shelf.Previously, most books were my textbooks, but I wanted to do some changes.I picked up the textbooks on a cartoon and put the books I read at spare time on the shelf.And then I started to clean my bedroom.Because mother cleaned it almost everyday, so my task was not so heavy.After I finished my own duty, I helped mother with other works.Before lunch, we finished all the housework.

　　上周六，我在家帮妈妈做了些家务。我的任务是打扫我的房间以及把书架上的书分类。早餐过后，我开始了我的工作。我先排列了书架上的书。显然，我大部分的书都是教科书，但是我想稍作改变。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。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。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。
