问题     Most animals seek shade when temperatures in the Sahara Desert soar to 120 degrees Fahrenheit. But for the Saharan silver ant,【C1】________from their underground nests into the sun’s brutal rays to【C2】________for food, this is the perfect time to seek lunch. In 2015 these ants were joined in the desert by scientists from two Belgian universities, who spent a month in the【C3】________heat tracking the ants and digging out their nests.  The goal was simple, to discover how the     【C4】________adapted to the kind of heat that can【C5】________melt the bottom of shoes.
    Back in Belgium, the scientists looked at the ants under an electronic microscope and found that their【C6】________, triangular hair reflects light like a prism (棱镜), giving them a metallic reflection and protecting them from the sun’s awful heat. When Ph. D. student Quentin Willot【C7】________the hair from an ant with a【C8】________knife and put it under a heat lamp, its temperature jumped.
    The ants’ method of staying cool is【C9】________among animals. Could this reflective type of hair protect people? Willot says companies are interested in【C10】________these ants’ method of heat protection for human use, including everything from helping to protect the lives of firefighters to keeping homes cool in summer.
A) adapting           I) remote
B) consciously        J) removed
C) crawling           K) species
D) crowded            L) specimens
E) extreme            M) thick
F) hunt               N) tiny
G) literally          O) unique
H) moderate                        [br] 【C4】
选项
答案 K
解析 名词辨析题。分析句子结构可知，how引导的宾语从句缺少主语。空格位于定冠词the之后，因此空格处需要填入名词。空格所在部分意思是：目的很简单，就是发现这种_______是如何适应高温的。由上文可知，此处the_______指的是撒哈拉银蚁，因此空格处应填入含有“动物，物种”意义的名词，故本题答案为K)species。在备选名词中，L)specimens容易与species混淆，用作复数时，specimens指的是用于测试或检验的样品，不符合语境，因此排除。
