That summer I drove west with a friend, and we _____ a little money doing odd jobs and as much as possible visited his relatives.
【正确答案】
A
【答案解析】解析：考查词组辨析。pick up可指“得到",pick up a little money doing odd jobs意为“靠做零工挣到点钱”。step up意为“加紧”，不能与money搭配。put aside“储存”和set aside“留出”这两个词组虽然都可以和money一起连用，但从该句的角度去理解不合题意。
