问题 The engine has more than three hundred______, made of a lot of different materials.
选项 A、compositions
B、components
C、compounds
D、combinations
答案 B
解析 近义词辨析。composition 意为“成分，合成物”，指物体内在固有的不可分割的组成部分，如： the composition of the soil (土壤的成分)；component 意为“成分，部分”，指用于机械装置的组成部分，如： Each of the components is useful in its degree．(每一个元件都有程度不同的用处。)compound 意为“混合物，化合物”，指组合以成为整体，如：Water is a compound of hydrogen and oxygen．(水是氢和氧的化合物。) combination 意为“联合，结合”，指合并、联合的行为，如：His character is a combination of strength and kindness． (他的性格是刚与柔的结合。)原句中是机器的零件，所以只有B)项符合。
