Doing housework
Last week, our class made a survey on doing housework among ourselves. According to the survey, 40 per cent of our classmates often do some washing such as washing clothes, dishes and vegetables. There are 35 per cent students cleaning the house. They sweep the floor and clean the window. 12 per cent students do some shopping for their families. And about 8 per cent of them do the cooking. However, there're 5 per cent students hardly doing any housework.
I think as a member of the family, it's our responsibility to do housework. We should learn to do some simple housework. Also, it's helpful for us to learn some living skills from it.
谢谢
