犹他州立大学的大卫·兰西教授研究了世界各地的家庭是如何处理家务的。

Lancy put beside them a plate covered with a fresh white napkin.

兰西在他们旁边放了一个盘子， 上面盖着干净的白色餐巾。

At about 18 months of age, Lancy says, most children become eager to help their parents, and in many cultures, they begin helping with housework at that age.

兰西说，大多数孩子约 18 个月大时，就开始渴望帮助他们的父母做家务，且在许多文化中，很多孩子在这个年龄就已经开始帮忙做家务了。

" We deny our children's bid to help until they are 6 or 7 years old, " Lancy says, " when many have lost the desire to help and then try to motivate them with payment."

“直到孩子们 6 岁或者 7 岁之前，我们都拒绝他们的帮助，那时许多孩子已经失去了帮助家务的欲望，然后家长试图用报酬来激励他们做家务。”
