Running a lever was once thought to be the prerogative of warm-blooded creatures, whose internal temperatures are independent of the weather. But, as Matthew Kluger reported in "The Importance of Being Feverish" (January 1976), lizards can also develop fevers, even though there is no question that they are cold-blooded. They raise their temperatures by moving into the sun or, in the case of Kluger’s experiments, under a sun lamp. And it seems to do them some good. Sick lizards kept in cages at feverish temperatures fare much better than their counterparts in normal mid cool environments.
Now, fever has spread to invertebrates(无脊椎动物). Recent studies have shown that crayfish and scorpions can develop fevers. Crayfish injected with bacteria and scorpions injected with prostaglandins(前列腺素) swam and scuttled to hot areas. (Prostaglandins are hormones thought to be instrumental in the development of a fever. )
Evidence is also mounting that moderate fevers have their benefits, which might explain why the fever process is so widespread. Leukocytes, white blood cells that are active in fighting bacterial infections, are more mobile at febrile temperatures. And fevers reduce the amount of iron available to bacteria. That reduction, combined with high temperatures, has been shown to inhibit bacterial growth.
The passage implies that ______.
选项
A、the fever process is widespread because moderate fevers have benefits
B、the reduction of fevers can inhibit bacterial growth
C、man can use sun lamp to raise lizards’ temperature
D、crayfish injected with bacteria have a purpose for moving to hot areas
答案
D
解析
本题所提供的四个选项均与文章内容相符,但在题目中有一关键词imply(暗示),这就要求所选答案不仅正确,而且在文章中并未直接表述,通过推理又不难得出。文章第二段中介绍:Crayfish injected with bacteria...swam and scuttled to hot are as.(注入细菌的小龙虾急忙游向炎热的区域。)由此不难推出D项中所说注入细菌的小龙虾具有向炎热区域移动的意图的结沦是正确的,因此本题最佳答案应为D项。
