Teenagers’ acting selfishly could be down to the wiring in their brains, scientists said recently.
Teenagers hardly use the area of the brain that analyzes other’s emotions and thoughts when considering a course of action.They are also less likely to consider their own emotions than adults do, said scientist Dr Sarahjayne Blakemore, from University College London.
Many areas of the brain change dramatically during the teenage years, with one part ---- the medial prefrontal cortex(内侧前额叶皮层) ---- continuing to develop way beyond adolescence.This is an area at the front of the brain associated with higher-level thinking, empathy (同情), guilt and understanding other people’s motivations(动机).
The researchers say they have now found that, when making decisions about what action to take, the medial prefrontal cortex is underused in teenagers.Instead, a back area of the brain involved in sensing and imagining actions, takes over.
Dr.Blakemore said: “Thinking methods change with age.As you get older you use more or less the same brain network to make decisions about your actions but the important difference is that the distribution of that brain activity shifts(改变方向) from the back of the brain to the front.
“We think that a teenager’s judgment of what they would do in a given situation is driven by the simple question: ‘What would I do?’.Adults, on the other hand, ask: ‘what would I do, given how I would feel and given how the people around me would feel as a result of my actions?”
In the study, teenagers and adults were asked questions about the actions they would take in a given situation while their brains were scanned using functional Magnetic Resonance Imaging.A second piece of research showed teenagers were less likely to think about how they would feel in another person’s shoes.
Dr Blakemore concluded: “ It is clear that teenagers are dealing with, not only massive hormonal shifts(激素变化), but also important neural(神经系统的) changes.”
1.When teens decide to take action, they ________.

My motivation for starting our family tradition of reading in the car was purely selfish: I could not bear listening to A Sesame Street Christmas for another 10 hours. My three children had been addicted to this cassette on our previous summer’s road trip.
As I began to prepare for our next 500-mile car trip, I came across a book Jim Trelease’s The Read Aloud Handbook. This could be the answer to my problem. I thought. So I put Roald dahl’s James and the Giant Peach into my bag. When I began to read aloud the tale of the boy who escapes the bad guys by hiding inside a giant peach, my three kids argued and wrestled in their seats. But after several lines, they were attracted into the rhythm of the words and began to listen.
We soon learned that the simple pleasure of listening to a well-written book makes the long miles pass more quickly. Sometimes the books we read became highlights of the trip. I read wilson Rawls’s Summer of the Monkeys as we spent two days driving to the beach. We arrived just behind the power crews restoring (恢复) electricity after a tropical storm. The rain continued most of the week, and the beach was covered with oil washed up by the storm. When we returned home, I asked my son what he liked about the trip. He answered without hesitation, “The book you read in the car.”
Road trips still offer challenges, even though my children now are teenagers. But we continue to read as we roll across the country. And I m beginning to see that reading aloud has done more than help pass the time. For at least a little while, we are not shut in our own electronic worlds. And maybe we’ve started something that will pass on to the next generation.
1.Why did the author start reading in the car?
A. She wanted to have a better journey. B. She wanted to keep a family tradition
C. Her children were addicted to music. D. She wanted to kill the time.
2.How did the children react after the author read a few lines?
A. They kept quarelling. B. They hid themselves.
C. They soon settled down. D. They continued to fight in their seats.
3.What can we learn about the author and her family’s trip to the beach?
A. They were caught in a storm. B. They enjoyed reading on the road.
C. They had a good time on the beach. D. They thought it had passed too quickly.
4.Which can be the best title for the text?
A. Better Reading than Traveling B. Books that Changed My Children
C. Road Trips Full of Challenges D. Reading Makes Great Road Trips

Teens don’t understand the big fuss. As the first generation to grow up in a wired world, they hardly know a time when computers weren’t around, and they eagerly catch the chance to spend hours online, chatting with friends. So what?
But researchers nationwide are increasingly worried that teens are becoming isolated, less skillful at person-to-person relationships, and perhaps numb to the cheatings that are so much a part of the e-mail world. “and a teen’s sense of self and values may be changed in a world where personal connections can be limitless,” said Sherry Turkle.
Another researcher, Robert Kraut, said he’s worried about the “opportunity costs” of so much online time for youths. He found that teens who used computers, even just a few hours a week, showed increased signs of loneliness and social isolation. “Chatting onine may be better than watching television, but it’s worse than hanging out with real friends,” he said.
Today’s teens, however, don’t see anything strange in the fact that the computer takes up a central place in their social lives, “School is busy and full of pressure. There’s almost no time to just hang out.” said Parker Rice, 17. “Talking online is just catch up time.”
Teens say they feel good about what they say online or taking the time to think about a reply. Some teens admit that asking someone for a date, or breaking up, can be easier in message form, though they don’t want to do so. But they insist there’s no harm.
1.She researchers argue that___.
A.teens may develop a different sense of values
B.nothing is wrong with teens' chatting online
C.teens can manage their social connections
D.spending hours online does much good to teens

A.use computers properly B.improve their school work
C.develop an interest in social skills D.reduce their mental pressures

A.teens' pleasant online experience
B.teens' computer skills and school work
C.the effects of the computer world on teens
D.different opinions on teens' chatting online

B.draw attention to teens' computer habits
C.suggest ways to deal with problem teens
