Unit 3Inventors and inventions 课时作业 Ⅰ. 阅读理解 (2020·黄冈市高三质量检测)One of the things that makes your smartphone so smart is that if you pull it out in the sun, it senses that—and dials up the screen brightness to compensate. But it's not aperfect solution. “First of all, it's still not bright enough—you have to remember how respectable sunlight is.” said ShinTson Wu, aphysicist at the University of Central Florida. The other problem, he says of the brightened screen, is it kills the battery. So Wu and colleagues have produced abatterysparing alternative: an antireflective screencoating, based on the eyes of moths. “Nature is so rich! We can learn alot from nature.” The thing Wu and others have learned about moth eyes, is that they're uneven, dotted with tiny projections. That uneven surface reduces the reflection of light off their eyes—thought to help the bugs escape predators (捕食者), and see better in low light. So Wu and his team built asimilar surface with tiny dimples (凹), to cut down on glare. He says the dimpled coating could improve the readability of a screen by five to 10 times, compared to anormal smartphone screen. The details Optica are in the journal . The tech hasn't been commercialized yet, and that could take afew years, which gives researchers time to take advantage of another property of these surfaces: they're flexible, meaning the possibility of bendable displays. Combine that with the bendy batteries we reported on in arecent podcast (播客), and it looks the smartphones of the future could be set for areal transformation. 篇章导读：本文是一篇说明文。飞蛾眼睛的凹凸不平激发了研究者开发一种未来可能会 变形的手机屏幕。 1．Why do the researchers develop the antireflective screencoating?
