【题目】Not many Chinese students do chores at home. They are busy with schoolwork on weekdays. And on weekends they have to spend lots of time on their homework. So they often watch TV in their free time to relax themselves. Parents think that children should spend time on their studies and learning more skills, for example, playing the piano and dancing. There is no need for them to do chores. The following is the result of a survey(调查) about how many students do chores.
