Do teenagers in small villages do chores at home? How about the teenagers in big cities? To know the answers, we made a survey（调查）last month. We asked 4,000 teenagers in China. Half of them come from big cities like Beijing, Shanghai and Guangzhou. The others are from small villages. We made a chart（图表）according to our survey. Let's have a look at it.
We can find out that teenagers in small villages do more chores than those in big cities. Maybe it is because they live a harder life. We will give our advice to parents in big cities. We think parents should give their children some chores to do because it's a good chance for teenagers to learn how to take care of themselves.
