20．“关爱生命，安全出行，争当安全模范公民”的教育活动，在全国各地轰轰烈烈地展开。“红灯停，绿灯行”是公民的基本素质。交通信号灯用红、绿灯，而不用蓝色、紫色等其它颜色的灯。对此，小明、小华、小宇三位同学展开讨论。
小明说：人的眼睛对红色光、绿色光比较敏感。用红绿灯作为交通指挥灯，容易引起视觉反应，可以提高人们的警惕性，减少交通事故的发生。
小华说：红光穿透能力比蓝色、紫色等其它的色光强，很远处就能看到；人的眼睛对绿色光敏感。
小宇说：红绿灯作为交通指挥灯，是国际通用的，并不具有科学依据。
（1）雾天，小明、小华和小宇一起在远处观看路口的红绿灯，收集有关“红色光穿透能力强”的证据。小明和小宇看到红灯亮时，小华却认为红灯不亮。此事实说明红色光引起的视觉效果与____________________有关；三位同学向路口的红灯走近，都感到红色光强度逐渐增强，表明色光的穿透能力与_______________________________有关。影响色光穿透能力的因素还有__________________________________________________（至少答出一条）。
（2）依据你的生活体验，并结合学过的物理知识，对小宇的说法作出评价： ___________________________________________________。
（3）红绿色盲的人不能分辨红绿灯颜色的变换。请你描述现行交通信号灯是如何让色盲的行人做到“红灯停、绿灯行”的或提出一条合理化建议。（回答一条即可）_________________________________________________。
（4）随着科技创新，传统的红、绿灯逐渐被超高亮度的发光二极管（LED）所替代。LED灯具有亮度高、颜色纯、耗电少、寿命长等特点，简述LED灯的广泛使用可能会给人们的生活与环境带来的影响。（回答一条即可）

Young people leave their parents' homes at different ages in different parts of the world. In the United States, a lot of college students do not live at home. Many choose to go to college in different cities-away from their parents. At college, they live in university housing. After college, most people prefer to living in their own homes. They often live alone, but some people rent apartments with others. These people are roommates. By the age of 22, few young people in the United States live with their parents.
Families stay together longer in many Asian countries and cities. In Hong Kong, for example, nearly all university students live with their parents. Rents in the city are very expensive, and few students have the money to pay for their own apartments.
Very few young people live alone or become roommates in a shared apartment. Many young people in Hong Kong continue to live with their parents after they marry.
