①How often do you help to do housework ②What housework do you often help your parents with
In fact, many parents make their children do chores around the house. For some families, teaching children what to do and how to do chores is easy. But in other families, getting children to do some housework can be a very big problem.
It is a good idea for parents to teach their children at an early age that all family members must work together to make the house clean, and each person must do his or her share of the work. Chores are good for children. Doing chores can teach children many important skills like working together. Chores also teach children what is fair. The skills and values from doing chores will do good to children all their lives.
However, most experts agree that the chores should fit the children. For example, young children can do the chores like picking up toys, putting books in the bookcase... to keep the home tidy. In fact, young children usually would like to do chores because they like doing what Mom or Dad does, and that helps them feel more grown-up. As the children grow older, many experts advise giving them more difficult chores like mopping the floor and walking the dog. The middle school students may spend more than two hours a night on their homework. Perhaps more chores on the weekend, not on weekdays can be helpful.
51．We can know from the result in chart (图表) that ________.
A．Few students do housework every day.
B．Half of the students do housework sometimes


参考句型：We should…；We shouldn’t…；We mustn’t…
