Correct or improve the translation of the following Chinese sentences.原文：家里最大的是我，才十三岁，就唱戏养家了。 译文：I was the eldest child and only thirteen and had to act to help support the family.改译：
【正确答案】：

AT THIRTEEN, AS THE ELDEST CHILD, I ACTED TO HELP SUPPORT THE FAMILY.

【题目解析】：and连接并列的三个成分，冗长且不很合理。as the eldest child作为插入语，表示当时主人公只有13岁，介词短语表示年龄更为合适。
