“100－1＝0”被一些管理学家奉为定律，意在提醒人们防止因1％的错误导致100

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. All family members must work together to make the house clean, and each person must do his or her share(份) of the work. We can do this by starting plan of chores and responsibilities(责任) when children are young.
Chores are good for children—even very young ones. Doing chores can teach children many important skills(技能) like working together. Jobs also teach children what is fair(公平). The skills and value(价值) from doing chores will be good to children all their lives.
