For the 182 people of Green Bank，West Virginia，modern conveniences like Wi-Fi，cellphones，microwaves，and even digital cameras are things of the outside world. Construction (建造) of the Green Bank Observatory (天文台) began in 1957.One year later，the government set up the National Radio Quiet Zone including the town of Green Bank.This town is next to the world's largest fully steerable radio telescope (可操纵射电望远镜)，which allows scientists to observe things like the stars in the sky.And in order for the radio telescope to listen to the most “distant (遥远的) voices of the universe”，it requires no interference (干扰) from the ground. The limitations (限用) on this town have allowed a return to a type of community connection that was common in the not-so-distant past.You can check out some of the discoveries the Green Bank Telescope has made on the website，where you can go deeper into all that scientists are finding in their studies and in the lives of the people of Green Bank.It is interesting to know that teens have little stress and everyone has a deeper connection to other people and the natural world. We can imagine what that would look like for us.Would we feel comfortable knocking on our neighbor's door to ask for a cup of sugar? How often do we find ourselves focusing on our Facebook when the people we love are sitting all around us? What could we get if we spent more time just in the quiet presence of others or just with ourselves and a good book? Maybe we can't (or don't want to) disconnect Wi-Fi，but maybe，we can try disconnecting it for a few hours a day and see how we feel.We may discover a new way of living that better serves our minds and our relationships with one another. 语篇解读　本文是一篇说明文。文章主要介绍了美国弗吉尼亚州西部格林班克镇人们没有使用Wi-Fi、手机等现代通讯设备的生活方式，并探讨了这种生活方式对当地人心理、社会联系以及生活质量的影响。 5．What is mentioned about the people of Green Bank?
