Now a paper in Science argues that organic chemicals in the rock come mostly from ________ on earth rather than bacteria on Mars.
选项
A、configuration
B、constitution
C、condemnation
D、contamination
答案
B
解析
形似名词辨析。四个名词均以con-开头、以-tion结尾。而且A与B的词义比较接近。A. con- figuration构造,配置,地形,表示构成的方式;B.constitution结构,体质,表示结构、构成、组成,侧重“组成成分”,是可以与“bacteria on Man”形成对应的;C.condemnation遣责,判刑;D.contamination污染,污染物。根据句意和逻辑B是答案。句意为:最近《科学》杂志上有一篇论文提出,岩石中的有机物来自地球本身的结构而非来自火星细菌。
