The town of Green Bank, West Virginia, is the site of the largest radio telescope in the world, so Internet connections and anything else that can create electromagnetic(電磁的) waves, such as smart phones and microwave ovens, are banned.

Green Bank is frozen in time, somewhere in the 1950s, because there’s a 33,000-square-kilometer zone of silence due to the telescope. Cell phone towers are forbidden.

The closer you get to the telescope, the greater the restrictions. There’s a 16-kilometer radius(半徑) around the observatory where radio-controlled items, even toys, cannot be used.

Telescope employees even work in a special room that blocks electromagnetic waves from leaving it. “Here imagine a submarine(潛艇), water cannot get inside, and so this room is an electric submarine. No electromagnetic waves can get into this room, just as you can’t go beyond it,” Michael Holstein, an observatory officer, said.

The size of a football field, the telescope is so sensitive that it could pick up signals sent from an alien world. And scientists can’t wait for that to happen.

“All the signals that we now receive with the help of telescopes are signals that come from cosmic objects — stars, galaxies. We have not yet received anything from intelligent civilizations,” scientist Richard Lynch said.

Local people respect the work of the scientists. “Yes, we are different. Many would say that we live the old-fashioned way, in the past. But for us, it’s just the way of life that we have always lived,” Sherry said.

“When we want to meet friends, we just call each other on a wire phone. And instead of sitting in front of your screen, we talk, we go fishing, to the mountains,” resident Sherry said.

For the latest news, residents read the weekly local newspaper. When she’s looking for a phone number, Sherry reaches for the phone book.

And instead of Facebook, Sherry enjoys daily conversations with her customers. In this town, everyone knows each other and communication is face to face.

A. The town is economically less developed.

B. Electronic products will affect the radio telescope.

C. They have got used to it and don’t want to change.

D. The radio telescope stops electronic products working properly.

What would work be like if you had no boss?Imagine you could make all your own decisions and no one told you what to do.

A Swedish software company,Crisp,decided to get rid of their CEO.First,they needed to find out what a CEO actually did.Then they shared those duties among staff and board members,which is exactly what they did.And the employees believes it's been a good change.An employee named Heinrik Kniberg says the company can now act faster,"If you want to get something done,you stand up and start driving that.Workers are also more active and satisfied."And any big decisions are made during the all-member meetings several times a year.

So,if it's working well for Crisp,could this model become more widespread? Online retailer(零售商)Zappos tried out a similar plan but had unpleasant results.Almost a fifth of its staff decided to leave,and CEO Tony Hsieh admitted that "self-management is not for everyone".Mr Houston,founder of file-sharing service Drew Dropbox,says that total freedom doesn't always feel good,because you no longer know what you're supposed to do,what is important and you're bumping up against other people."

Claire Metcalf

“The concept is great, but the staff are the ones who really make it. ”she says. “It takes a lot of discipline to always be friendly, but the staff at Staybridge Suites do that. They genuinely care about you.”

Andrew Roberts

“One of the best things is having my own kitchen. I often end up working late and I don’t fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. ”

Pauline Robinson

“What I love about it is the way that you are treated by the staff,” she says. “Some of the staff have been there all that time and they do look after you well. As a woman staying on my own, it is reassuring that they look out for you, and recently when I was poorly they even brought things I needed to my room. ”

Ryan Ruckledge

“The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I’m able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don’t want that.
