The practice of paying children an allowance became popular in America about 100 years ago. Nowadays, American kids on average receive about $800 per year in allowance. But the vast majority of American parents who pay allowance tie it to the completion of housework. Although many parents believe that paying an allowance for completing chores benefits their children, a range of experts expressed concern that tying allowance very closely to chores may not be ideal. In fact, the way chores work in many households worldwide points to another way.

        Suniya Luthar, a psychologist, is against paying kids for chores. Luthar is not opposed to giving allowances, but she thinks it’s important to establish that chores are done not because they will lead to payment, but because they keep the household running. Luthar’s suggested approach to allowance is compatible with that of writer Ron Lieber, who advises that allowances be used as a means of showing children how to save, give, and spend on things they care about. Kids should do chores, he writes, “for the same reason adults do, because the chores need to be done, and not with the expectation of compensation.”

        This argument has its critics, but considering the way chores are undertaken around the world may change people’s thinking. Professor David Lancy of Utah State University has studied how families around the world handle chores. 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. They begin with very simple tasks, but their responsibilities gradually increase. And they do these tasks without payment. Lancy contrasts this with what happens in America. “We deny our children’s bids 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. The solution to this problem is not to try to use money as an incentive to do housework, but to get children involved in housework much earlier, when they actually want to do it.”

解析：D。根据题干中的David Lancy和American parents可定位至原文最后几句话。文章倒数第二、三句说到，兰西对比了美国的情况。兰西指出，直到孩子六七岁的时候，父母才会允许他们帮忙。到那时，很多孩子已经失去了想要帮忙的意愿，于是家长们就试图用报酬来激励他们。但这种做法是错误的，文章最后一句兰西提出：解决这个问题的办法不是用金钱来激励孩子做家务，而是让孩子在他们真正想做家务的时候及早地参与进来。D项是对这一内容的同义概括，其中bids to help对应定位句中的when they actually want to do it，故正确答案为D。

错项排除：A、C两项中的关键词example和Teach在原文均无依据，故可排除。B项利用原文第二段最后一句出现的compensation作干扰，但这是罗恩提出的观点，并非兰西所说。而且兰西只是建议不要用金钱来激励孩子做家务，并没有建议让孩子无偿做家务，且第三段中提到的And they do these tasks without payment也只是对其他文化中孩子开始做家务的年龄的客观描述，并不是大卫·兰西的建议，故B项属于过度推断，可排除。
