He bought a book with the 50 dollars and then his money .
A. remaining; was used up
B. remaining; ran out of
C. remained, ran out
D. remained, gave out

(答案→)A. remaining; was used upB. remaining; ran out of C. remained, ran outD. remained, gave out解析：句意：他用剩下的50美元买了一本书，然后他的钱就用完了。Remain“剩下”是不及物动词，所以做定语用现在分词，所以排除CD，use up“用完”是及物动词，用被动语态，run out of“用完”也是及物动词，需要被动语态，所以B是错的，选A。

这个问题我还想问问老师呢
