查询词典 grating

Biologists find it most grating that the impetus for this postdarwinian convergence comes chiefly from mathematicians, physicists, computer scientists, and whole systems theorists-people who couldn't tell the difference between Cantharellus cibarius and Amanita muscaria if their lives depended on it.

这门科学就是复杂科学。生物学家们发现，对于那些正汇聚起来的后达尔文主义潮流来说，它们的推动力主要来自于数学家、物理学家、计算机科学家还有那些整体理论的研究者，也就是说，是这么一批人：如果有朝一日这些人要靠吃蘑菇来度日的话，他们可分不清楚Cantharellus cibarius和Amanita muscaria[1]（这两种蘑菇中有一种是有毒的）。
