There are 12 children in Lucy’s 13-year-old birthday party.They are from A,B and C three families,and there are 4 children in each family.Of course,Lucy is from one of the families.在露西的13岁生日聚会上，共有12个小孩，并分别来自A、B、C三个不同的家庭，当然，露西来自其中一个家庭。

Of the 12 children,they are less than 13 years old except Lucy.They are of different ages.这12个孩子中，除了露西13岁外，其余的都不到13岁，而且每个孩子的年龄都各不相同。

From numbers 1-13,all of them stand for the ages of the children except one number.Add up all the ages of the children in the family,the results are as follows:在 1～13这13个数字中，除了某个数字以外，其余的数字都表示某个孩子的年龄。把每个家庭孩子的年龄加起来，得出以下结果：

Which family does Lucy belong to?露西属于哪个家庭？

A家庭(Family A):Total of the ages is 41,a 12-year-old child included.年龄总数 41，包括一个12岁。
