单项选择题

How many times a day do you check your email When you wake up Before bed A dozen times in between The technology that was supposed to simplify our lives has become the ultimate time-suck: the average teen spends more than seven hours a day using technological devices, plus an additional hour just text-messaging friends.
The advantage to all that gadgetry, of course, is connectedness: email lets us respond on the go, and we are in touch with more people during more hours of the day than at any other time in history. But is it possible we’re more lonely than ever, too That’s what MIT professor Sherry Turkle observes in her new book, Alone Together, a fascinating portrait of our changing relationship with technology, the result of nearly 15 years of study. Turkle details the ways technology has redefined our perceptions of intimacy and solitude--and warns of the perils of embracing such virtual relationships in place of lasting emotional connections.
For Turkle, a psychologist by training, the biggest worry is what all this superficial engagement means for us developmentally. Is technology offering us the lives we want to live "We’re texting people at a distance," says the author, the director of the MIT Initiative on Technology and Self. "We’re using inanimate objects to convince ourselves that even when we’re alone, we feel together. And then when we’re with each other, we put ourselves in situations where we are alone--constantly on our mobile devices. It’s what I call a perfect storm of confusion about what’s important in our human connections."
What can’t be denied is that technology, no matter its faults, makes life a whole lot easier. It allows us to communicate with more people in less time; it can make conversation simple--no small talk required. But it can also be seductive, providing more stimulation than our natural lives make possible. "The adrenaline (肾上腺素) rush is continual," Turkle says of our wired lives. "We get a little shot of dopamine (多巴胺) every time we make a connection." One high-school student she spoke with put it simply: "I start to have some happy feelings as soon as I start to text."
But are any of those feelings equal to the kind we feel when engaged in real, face-to-face intimacy Online, you can ignore others’ feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is less empathetic than ever. That doesn’t spell disaster, says Turkle--but it does mean we might want to start thinking about the way we want to live.
