问题 Although ______ before the war, the engine is still in perfect order.

选项 A、building
B、to build
C、built
D、Being built

答案C

解析 考查分词作状语的用法。分词可以和连词一起用,接近于状语从句的紧缩形式。本题的build与主句主语engine是被动关系,所以要使用过去分词built,分词结构等同于although it was built before the war。例如:Unless (it is) changed, this law will make life difficult for farmers. (除非加以修改,否则这条法律将给农民的生活造成困难。)
