　　You might think people all over the United States have Wi-Fi-wireless Internet service-and mobile phones.But there is no such service in Green Bank，West Virginia，a tiny town four hours from the US capital，Washington D.C.Fewer than 150 people live in Green Bank，which has two churches，an elementary school and a public library.It is also home to the largest radio telescope in the world.

　　There is a ban(禁令) on Wi-Fi in Green Bank，along with anything else that can create electromagnetic(电磁的) waves.Officials say the waves could disturb the signals(信号) the telescope receives.

　　For many Americans，a visit to Green Bank is a little like returning to the 1950s.To get there，you must read road signs because there is no GPS service in the town.People can connect with the Internet through telephones，but wireless service is not allowed.

　　The observatory(天文台) is one of the largest employers in the area.The federal National Science Foundation (NSF) spends about 8.2 million a year to operate the observatory，telescope and educational center.

　　Jonah Bauserman is a technician.If he supposes there is a signal that is not allowed in the zone，he drives to the house where the signal is coming from and checks it.but once a week，when the device is cleaned，some banned devices are allowed near it.

　　People in the town respect the work of the scientists.And they say they are happy to live without Wi-Fi and mobile phones."You know，instead of sitting here on our phones and other devices we're out fishing，hunting and going to each other's houses." Everyone knows each other and communication is almost always face to face.
