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.

We have been travelling for more than a week already but arrived in Saudi Arabia today. Most people here wear traditional type of long and loose clothing that cover the whole body. Saudi Arabia is in the desert, and in summer, the weather is extreme hot. One of the tour guide told us that it gets as hotter as 50℃ every summer. Wear this kind of clothing may be very comfortable in that weather, but this is winter and quite cool now. During the day in winter, it was about 22℃ and about 13℃ in the evening. I think I will find the weather a bit of cold when we return to China.

Recently a post went popular on the US question website Quora. It asked, “Have you ever been considered more attractive in a country 4. than your own?”
Many replies made 5. clear just how much more attractive they were considered in other country, and why.
Lolyta from Indonesia wrote, “In my home country, I am not considered beautiful, 6. when I went to Europe I got a lot of attention.” Pooja Gautam from Nepal shared a similar experience. Women with lighter skin always got more attention than she 7. in her country. But in Poland, she has gotten 8.(usual) high levels of attention from locals. “Tanning salons (晒黑沙龙) are a big thing in Polish cities,” she wrote. “Some Polish people find it hard to believe 9. I tell them that many Nepalese people carry 10.(umbrella) on hot, sunny days to stop their skin from turning darker.”
