1. _______ the last two years, the total cost has been reduced by 19 percent.
A. To compare with B. Comparing to C. Comparing with D. Compared with
【答案】D
【解析】
【详解】考查动词短语辨析和非谓语动词。句意：与过去两年相比，总成本下降了19%。compare to…把……比作……，compare with…把……和……比较，根据句意可知，此处是把现在和过去比较，需用固定短语compare with，本句已有谓语动词 reduced，且空处没有连词，所以空处需用非谓语动词作状语，动词compare与主句主语the total cost之间是被动关系，所以空处需用过去分词compared作状语。故选D。
