问题 Concrete, which is used in a wide range in modern society, ______ of cement, sand and gravel mixed with water.

选项 A、consists
B、composes
C、concentrates
D、comprises

答案 A

解析 题意是:在现代社会,大范围使用的混凝土由水泥、沙子和沙砾混上水______。 [A]consists“由…构成,包含有”,consist of“组成”,为固定搭配,指整体由几个部分或几种材料构成,符合题意。[B]composes“组成,构成”,主语为组成前的各个部分,宾语为组成后的一个整体;[C]concentrates“集中,聚集”;[D]comprises“构成,组成”,为及物动词,直接跟宾语。因此,这三项都不符合题意。
