3 . Don't get mad the next time you catch your teenager texting when he promised to be studying. He simply may not be able to resist. A University of lowa(UI) study found teenagers are far more sensitive than adults to the immediate effect or reward of their behaviors. The findings may help explain why the initial rush of texting may be more attractive for adolescents than the long-term pay off of studying.
"For the teenager, 'the rewards are attractive." says Professor Jatin Vaidya,an author of the study. "They draw adolescent. Sometimes, the rewards are a kind of motivation for them. Even when a behavior is no longer in a teenager's best interest to continue, they will, because the effect of the reward is still there and lasts much longer in adolescents than in adults ."
For parents,that means limiting distraction (分心的事情)so teenagers can make better choices. Take the homework and social media dilemma: At 9 p.m., shut off everything except a computer that has no access to Facehook or Twitter, the researchers advise. "I'm not saying they shouldn't be allowed access to technology," Vaidya says. But some help in netting their concentration is necessary for them so they can develop those impulse-control skills.”
In their study,Vaidya and co-author Shaun Vecera note researchers generally believe teenagers are impulsive(冲动的),make bad decisions,and engage in risky behavior because the frontal lobes(额叶)of their trains are not fully developed. But the UI researchers wondered. whether something more fundamental was going on with adolescents to cause behaviors independent of higher-level reasoning.
"We wanted to try to understand the brain's reward system how it change from chillhood to adulthood," Says Vaidya, who adds the reward character in the human brain is easier than decision-making. “We've been trying to understand the reward process in adolescence and whether there is more to adolescence behavior than an under-developed frontal lobe,”he adds.For their study ,the researchers persuaded 40 adolescents, aged 13 and 16,and 40 adults, aged 20 and 35 to participate.
In the future,researchers hope to look into the psychological and neurological(神经学上的)aspects of their results.

5 . It is quite apparent that competition surrounds every aspect of human life whether in the United States or the Amazon rainforest. Without it we would not have grown into primates (灵长类动物) . Or we would probably still be struggling to sharpen a bronze tool while crawling around on four legs in search of meat. Without competition, Columbus wouldn’t have discovered America and Edison would never have invented the light bulb.
Friendship, like all relationships between two people, involves competition. It isn’t competition in a traditional sense because there are no goals to be scored and no prize. Perhaps the ecological definition --- the simultaneous (同时) demand by two or more organisms for limited environmental resources, such as nutrinents, living space, or light --- better explains it.
As in nature, high school life is governed by a set of laws, similar to a shortened version of Darwin’s theory of evolution, overpopulation, and competition. There is an abundance of high school students and to distinguish them, ranking and categorizing (分类) take place. In high school, friendships learn to coexist with competition even though at times the relationship is rough. In fact, in some circumstance, competition is too much of a burden for a friendship to bear, causing it to fall apart. College admission is the final high school objective. Four years of hard work is to achieve good grades, and a student’s fate is determined not only by these achievements, but by the records of thousands of other seniors trying to achieve a similar recognition.
Nevertheless, by necessity, competition between students exists in all aspects of high school life. It sets and improves the standards in everything from sports to schoolwork. A healthy, friendly competition can have only benefits, but when it becomes too fierce, jealousy (妒忌) can tear friendships apart. Yet, despite all this, without competition, we would be lost.

7 . Researchers define self-control or self-discipline as“ability to control or change one’s inner responses”.
In their study,205 adults were given smart phones and required to report their emotions at random moments throughout the week.
The researchers found that the more self-control people had,the more satisfied they were with their lives in the long run.
These researchers also figured out that people high in self-control are simply less likely to find themselves in situations where that’s even an issue.They don’t waste time fighting inner battles over whether or not to eat a second piece of cake.
A.In a word,they are not bothered about such little desires. |
B.Researchers checked these general ideas through a survey and study. |
C.It is generally believed that in the long run self-control can make people happier. |
D.Meanwhile,they were also asked to report whether they were experiencing any desires. |
E.However,people with more self-control were also more likely to be happy in the short run. |
F.But they are still uncertain why some people are more able to control their inner responses. |
G.Most adults reported they failed to control their desire to play video games before an exam. |
8 . We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices(装置) well after they go out of style. That’s bad news for the environment — and our wallets — as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life — from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation — Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. "The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices — we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放)more than doubling during the 1992 to 2007 window.
So what's the solution(解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.

However, in today’s world, stars are regarded as role models along with the heroes listed above, despite their intentions or actions. Teens attempt to imitate their actions for two major reasons. Firstly, to be fashionable and accepted by popular culture, and secondly because stars’ actions are so well documented by the media that it seems to grab our attention and turns it to following stars’ lives. Much of the reports about stars is shocking and exhibits bad morals or lifestyles that aren’t right for teenagers. In addition, almost everything stars do is described beyond truth to make a shocking story by taking it to the next level.
However, teens must take responsibility for their actions. We can’t always blame stars for influencing us. Only you have control over yourself and only you choose to do something. Our bodies and actions are in the hands of no one else.
Now, whoever said stars are role models? Whether they choose to be or not, stars set examples as soon as they step into the spotlight. With reporters following and recording every move they make, it is impossible not to be watched and then be imitated. These people influence teens whether or not they want to. Why should someone who doesn’t want to be setting an example set one? So,should we look up to them or to people who are true and good role models? It’s our responsibility as teens to know right from wrong, and it’s time for us to take responsibility for our actions. In doing so,we will lean toward those inspiring people that want to be setting an example, and follow in their steps to be like them.
