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歲生日聚會上，共有12個小孩，并分別來自A、B、C三個不同的家庭，當然，露西來自其中一個家庭。

Of the 12 children,they are less than 13 years old except Lucy.They are of different ages.這12個孩子中，除了露西13歲外，其余的都不到13歲，而且每個孩子的年齡都各不相同。

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這13個數字中，除了某個數字以外，其余的數字都表示某個孩子的年齡。把每個家庭孩子的年齡加起來，得出以下結果：

Which family does Lucy belong to?露西屬于哪個家庭？
