阅读理解 Have you ever imagined that your T-shirt can cool you down by up to 5℃ on these hot summer days? Thanks to a recent discovery, the possibility is getting closer. While there are many technologies that manage to keep the body warm, this amazing invention aims to offer real comfort for those who want to feel cool and fresh on extremely hot days. Its inventors, engineers Ma Yaoguang of Zhejiang University and Tao Guangming of Huazhong University of Science and Technology in China, took a completely new technique. They designed a special textile that can take in body heat and give off its energy into space. This means that, even when it looks like you are wearing a regular shirt, you are actually wearing something that works like a mirror. Research at Stanford University in 2017 had already managed to cool the wearers by 3℃, but this experiment was limited. So researchers still need to do more experiments to see the new technique to decide how effectively the new material cools while the wearers are standing or walking, and not directly facing the sky, like in their experiments. They also need to examine how well it works when T-shirts are not in close touch with the skin. Inventors Yaoguang and Guangming note that the new material will increase the costs by just 10 percent."It means everybody can get a T-shirt and the cost is basically the same as their old one," Yaoguang said. So if you are an athlete or simply someone that has to deal with the extremely high temperatures, be patient because your days of feeling hot and bothered may be coming to an end! （1） What is the purpose of the new invention? A . To keep people warm. B . To help beat the heat in hot weather. C . To find out the wearers' temperature. D . To protect clothes from becoming wet. （2） How does the special product work? A . By sending out absorbed heat. B . By turning sunlight into energy. C . By keeping heat out completely. D . By using light colors to reflect sunlight. （3） What is the main idea of Paragraph 3? A . The invention needs further testing. B . The studies in 2017 lack evidence (证据). C . The new textile has a good cooling effect. D . The new textile applies to various situations. （4） What's the writer's attitude towards the invention? A . Doubtful B . Objective C . Supportive D . Indifferent 答案： B A A C
