Many teenagers(青少年) feel that the most important people in their lives are their friends．They believe that their family members don’t know them as well as their friends do．In large families, it is quite often for brothers and sisters to fight with each other and then they can only go to their friends for some ideas．

Let’s face it: Teenagers spend hours texting, socializing on Facebook and playing video games.And it’s driving their parents nuts.
Sure, there are real dangers connected with all this screen time—everything from cyberbullying(网络欺凌) to couch-potato obesity.Not to mention driving while texting, and shortened attention spans(持续时间).
Douglas Gentile, who studies the effects of media on children, says texting, Facebook and video games are not naturally bad.Nor are they naturally better or worse than watching TV, although they do lead to different risks, such as cyberbullying.
But research has shown that the more time kids spend in front of screens—whether it’s TV or instant-messaging—the worse their school performances are.“That doesn’t mean it’s true for every kid, but it makes sense, that for every hour a kid is playing video games, it’s an hour that they’re not doing homework or reading or exploring or creating,” he said.If screen time is taking the place of doing their homework, that’s bad.But if their homework is done, well, so what?
The study also found that the more time kids spend with media, the lower their grades and levels of personal satisfaction are.Gentile said the influence of screen time on school work can be reduced by what he calls “protective factors”.Those might include good teachers and a high-performing school, love of reading, coming from a family where education is valued.“If you had all these protective factors, then that one little risk factor, who cares?”
One thing parents should worry about is the way electronic devices encourage multitasking（多任务处理).
“As adults, your response speeds up, you’re quicker to look over your shoulder and notice little noises or lights.However this is not what the kids need when they get to the classroom.Scanning to see when the next message comes may not be good for kids.The more distractions(分心的事物) you have, the worse your performance is.” Getting kids to turn off their phones, iPods in order to let them concentrate（集中) on homework is a fight worth having.
What statement may Gentile agree to?

A．Kids get bad marks when using Facebook.

B．TV or texting affects kids equally.

C．Kids prefer video games to books.

D．Watching TV is better than playing video games.

By saying “one little risk factor”, Gentile referred to ________

A．Are kids suffering cyber bullying on Facebook?

B．Are texting and Facebook worse for teens than TV?

C．Are kids willing to turn off their electric devices?

D．Are texting causing kids to lose interest in reading?

If you saw another kid ride her bike too fast around a corner and fall down, you might ride your bike more slowly on that turn.Yes, we humans are very sensitive to others’ mistakes.And the same is true for other animals.Animals mess up all the time.They might eat poisonous leaves, fall off a tree or let their prey(猎物) escape.By watching others fail, an animal can avoid making the same mistakes, thus improving its chance of survival.
Scientists believe that one part of the brain helps animals process information about others’ mistakes.Cells(细胞) in that part appear to become more active when a person sees someone else making a mistake.But researchers didn’t know whether individual cells in this part of the brain play different roles in discovering mistakes.
To investigate（调查） the brain’s response(反应) to mistakes in more detail, the researchers taught a game to two macaques, a type of monkey.One monkey could press a yellow or green button while the other watched.If the first monkey pressed the right button, the team gave both animals a treat.Every couple of rounds, the two monkeys switched roles.Meanwhile, the scientists watched individual cells in the animal’s brains.
When the first monkey messed up the game by pressing the wrong button, a group of cells in the second monkey’s brain fired.But if the second monkey also made the wrong choice during its turn, some of the cells in that group didn’t respond.Those unresponsive cells reacted specifically to mistakes made by others, not to the monkey’s own mistakes.
Scientists believe other parts of the brain also might help people process information about another’s mistakes.“You start to think about this other person and see things from his angle.” Ellen de Brujin, told Science News.She studies the brain at the University of Leiden in the Netherlands.
According to Paragraph 1, animals’ ability to learn from others’ mistakes______.

A．helps them to survive better

B．used to be ignored by humans

C．is being lost because of humans

D．ensures that they will never fail

From the game the scientists taught to two macaques, we can see ______.

D．how the brain responds to mistakes

A.the same buttons

C others’ mistakes
D.one’s own mistakes
