It [my first week's earnings] was given to me because I had been of some use in the world! And I became a contributing member of my family.
A、I could now bring money home.
B、I could now contribute to society.
C、I became a useful person in the world.
D、I was now able to do more for my family.
【正确答案】：A
【题目解析】：原句译文：这钱给了我是因为我对社会有了点用处；还有，我已经能为家里做点贡献了。本句中contribution实际上指的是作者可以为家里挣钱，帮助解决家人的负担，因此A项的解释最为清晰；B、C项均没有表达出为家里做贡献的含义，D项不如A项简洁明了。答案为A。
