    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.

选项

答案 F

解析 动词辨析题。空格位于动词不定式符号to之后,介词短语for food之前,因此空格处需要填入动词原形。空格所在部分意思是:但对于撒哈拉银蚁来说,从它们的地下巢穴爬到酷热的阳光下_______食物,这是寻找午餐的完美时机。由后面的seek可知,空格处应填入含有“寻找,搜寻”意义的动词,故本题答案为F)hunt。
