2021全国卷新高考英语阅读与写作专题拓展提升（20） 空调替代品：红外线反射涂料帮助建筑降温 导读 一种旨在通过反射太阳光来冷却建筑物的双层彩色涂料的新形式可能会成为空调的环保替代品。   双语阅读 A two-layered paint that reflects infrared light while maintaining its colour could help keep buildings and vehicles cool under hot sun. This could help reduce energy used in cooling, such as by air conditioners. 现在有一种既能反射红外线又能保持其颜色的双层涂料，它可以帮助建筑物和车辆在炎热的阳光下保持凉爽。这将有助于减少空调等制冷设备的能耗。 This coating was developed by Yuan Yang at Columbia University in New York and his colleagues. It consists of a top layer of commercial paint, which provides the colour, and a bottom layer made of a polymer similar to Teflon, which reflects infrared light. 这种涂层是由纽约哥伦比亚大学的袁洋和他的同事们开发的。它由上层提供颜色的商用涂料，和下层可以反射红外线的类似于特氟龙的聚合物组成。 When the sun shines on an object coated with this paint, the top layer absorbs certain wavelengths of light, depending on the paint’s colour, while the bottom layer reflects infrared light, preventing the object from heating up. 当阳光照射在涂有这种涂料的物体上时，根据涂料的颜色，顶层吸收特定波长的光，而底层反射红外线，防止物体升温。 ​ A similar c
