Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It’s awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

It may sound risky, so many teens stay within their own social circles to find rides, and don’t branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

“I think the digital connection of young people is really key, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they’ve been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.

The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn’t the car any more because there’s technology out there connecting you to a car.”

According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver’s license compared to six in ten today. So it’s not that surprising that on my 16th birthday I wasn’t rushing to get a license but an iPhone.

“Driving, for young people, does mean they have to disconnect from their technology, and that’s a negative. So if they could sit in the passage side and still be connected, that’s going to be a plus.” Schor continued.

To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

场景一：“我们的办公地点非常狭小，因此空间常常很拥挤。整个办公场地是开放式设计的，基本没有正规办公室。我们一般在会议室进行面试，但是有一次会议室用于展示活动，所以有两位候选人是在我的隔间逐一进行面试的。这次面试对于我来说简直是一场噩梦。环境嘈杂、人们走来走去，尽管事先我警告团队不要打扰我，但还是有三个人来打扰我。候选人都处理得很好，但是这对他们是不公平的，因为大家都很难将注意力集中在面试上。”

场景二：“我们招募新员工的时候组建了一个招聘小组对各个应聘者分别进行面试。小组成员有销售经理、人力资源部经理和我。问题是，人力资源部经理好像觉得在招募方面自己懂得多，她希望我们能附和她的意见。我感到自己不受重视，似乎我的意见毫无用处。这简直可笑，想想看我才是那个将和新员工共事的人！”

场景一中采用的面试方式是（）。

A、个别面试

B、成组面试

C、小组面试

D、会议型面试
