1 . For many adolescents, “screen time” is almost a full-time job that could lead to obesity, diabetes and other health issues, a Canadian researcher says.
Adolescents now spend an average of six hours a day in front of some type of screen, whether it’s a television or computer screen or one of the many portable devices now popular with young people, studies done by Dr. Ian Michael Janssen show. “They spend more hours daily in front of a screen than they do in a classroom in a given year,” said Janssen, a researcher at Queen’s University in Kingston, Canada
. The result is a rise in obesity rates among adolescents. Unfortunately, fixing the problem isn’t as easy as simply cutting down screen time, Janssen cautions. “Decreasing screen time will not automatically increase physical activity levels,” said Janssen, Some active kids also spend a lot of time in front of television and computer screens, and some kids who have low screen times also have low levels of physical activity, he points out.
As well, screen time is not necessarily bad, Janssen said. “The tricky part is that children today need to be using computers,” he said. Computers are required for schoolwork, and technological skills are important for future job prospects. The quality of screen time matters too, along with the quantity---consider the negative health messages found in food advertising during children’s shows, he said. Ideally, children should aim for no more than two hours of recreational screen time a day.
Janssen’s real worry about the rise in childhood obesity rates is not that there are now rare cases of type diabetes in kids, where once there were none, but the health problems these children are likely to face in the future as adults, including high blood pressure, high cholesterol and cardiovascular disease.

2 . Some young Cambodians are learning a new sport — skateboarding. The country’s first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital.
Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea，who has been skating for 6 months，says skating has already become his favorite sport.
The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards.
A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. Skateistan started its work in Afghanistan years ago. Rory Burke is working with the group which expanded to Cambodia last year.
Rory Burke points out, “Yeah, it’s definitely not a typical Cambodian pastime (消遣). And I think the idea of ‘why skateboarding’is that it’s not been done before here. We want to use skateboarding as something saying, ‘Hey，this is new，this is something different.’And that kind of itself becomes a little bit of hook. People see it and they think and they say, “Wow, ‘what is that?’，and they want to get involved. ”
Skateistan partners with local groups that work with young people. The park is on the grounds of the group known as PSE, where children attend school and learn a trade. There are almost one hundred twenty participants. They all come from troubled lives.
Seventeen-year-old Sang Rotha is a student at PSE. “Sometimes I don’t do well on subjects like math,”he says, “I feel bad when I find it hard to keep up with my lessons. So that is why I skateboard—to improve my bad feelings. ”
He says he began skateboarding more than a year ago. Before he started training, it seemed very easy. But it was very difficult to learn tricks, and he got hurt a lot from falling off.
Rory Burke says learning to deal with the difficulties is part of the lesson for these young skateboarders.

| B．It is a good sport to help regain good feeling. |
| C．It originated in Afghanistan years ago. |
| D．It is as popular as Khmer boxing in Cambodia. |
| A．something strange | B．something quite new |
| C．something different | D．something attractive |
| A．a sport liked by most young Cambodians |
| B．an increasingly popular sport in Cambodia |
| C．a sport used to better young Cambodians’ life |
| D．a good way to train young Cambodians’ learning skills |
