问题 As steel plants have become more ______, maintenance and adjustments of equipment have become a large share of the cost of running the plants.
选项 A、allied
B、drafted
C、automated
D、duplicated
答案C
解析 形容词辨义。allied意为“联合的，同盟的”，如：the Allied invasion of southern Italy(盟军对意大利南部的入侵)；draft是动词，意为“起草”，如：draft a speech(拟一份演讲稿)，其过去分词不作形容词用； automated意为“自动化的”，如：automated teaching(自动化教学)；duplicated意为“复写出的”，不用于比较级结构。由后半部分可推知，之所以仪器维修和调整占用了企业运行所需的大部分开销，就是因为这种自动化程度更高了，所以应选C)。
