In our family, everyone has to do chores, even my little sister. 
My parents are very busy. They need to work and take care of me and my sister. After work, mother often does laundry and cook for us, and father fix car and clean the yard sometimes.
I help my mother make dinner sometimes because I think she is very toilsome（辛苦的）. And mother washes the dishes but I sometimes help her out.
My sister goes to kindergarten so I sometimes take my sister there when my parents are busy.
I love my dad's car and so, I often wash the car for him when he is busy with work.
Even my sister is four, she can’t do many things. But when she gets up, she has to make her bed. 
This is my family. We live happily and harmoniously（和睦地）.
