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。
