Scientific Progress towards Extending Life Expectancy
In one experiment using anti -ageing chemicals, the life of 【R37】______ was extended by half. Besides, 【R38】______ like the ones which control the ageing process in these animals have also been found in other species. Unfortunately, however, experiments on 【R39】______ have been less successful: while they live longer, the 【R40】______ controlling their growth are also affected with the result that they grow less.
A chemicals B earthworms C fruit flies D genes
E hormones F human beings G mice H organisms [br] 【R38】
选项
答案
D
解析
文章提到,在确定了对蚯蚓寿命长短似乎起控制作用的两个基因(genes)后,在果蝇、小鼠和人类等多种生物体(organisms)中也发现了类似基因,故答案选D。试题的control the ageing process和原文的control how long…lives对应,found in organisms as various as…则和found in other species对应。
