    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.

选项

答案 E

解析 形容词辨析题。空格后是名词heat,因此空格处需要填入形容词。由句意可知,来自比利时的科学家在撒哈拉沙漠中研究撒哈拉银蚁,in the_______heat是说明撒哈拉沙漠的环境。众所周知,撒哈拉沙漠是极度炎热的,因此空格处应填入含有“非常的,极度的”意义的形容词,故本题答案为E)extreme。
