Most animals seek shade when temperatures in the Sahara Desert soar to 120 degrees Fahrenheit. But for the Saharan silver ant, （1） from their underground nests into the sun's brutal rays to （2） 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  （3）    heat tracking the ants and digging out their nests. The goal was simple, to discover how the  （4）  adapted to the kind of heat that can  （5）  melt the bottom of shoes.

Back in Belgium, the scientists looked at the ants under an electronic microscope and found that their （6） ，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  （7）  the hair from an ant with a （8）  knife and put it under a heat lamp, its temperature jumped.

The ants' method of staying cool is  （9）  among animals. Could this reflective type of hair protect people? Willot says companies are interested in （10）  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.
