We’d been flying for hours, deeper and deeper into the desert of southeastern Niger. The mission: to find what is probably the last wild population of the great Saharan antelope called the addax (旋角羚)—the most endangered animal of its size in Africa.
Pilot Peter Ragg flew our bright red helicopter low over two parallel dunes (沙丘). The pale sand below us was dotted by the black bushes, the plants that are favorite food for the addax. Then, almost as if the dune extruded (使突出) them, two perfect addaxes appeared. Their long tails swung from side to side as they ran, heads held high on thick necks, horns reaching for the sky. We made a few turns in the plane, then let them be. In just a few seconds they were swallowed again by the Sahara. Soon they could just as easily disappear from the planet.
In September 2004 the government of Niger and a small NGO called SOS Faune du Niger surveyed this last known pocket of wild addaxes. They counted 128 individuals. Since then, the number has dropped as hunters have taken more for meat. How many addaxes remain in the Sahara is anybody’s guess, but those that do survive could be considered the living dead: There may not be a viable (能生存的) population left to reproduce.
I’m now helping to make an emergency plan for the last wild addaxes. With a few hundred thousand dollars, some trucks, and a strong group with the local Toubou guides, we may just be able to save these guys from extinction.

Researchers found that compared with teens who spent much of their free time in front of TV sets, those who were physically active often had higher self-respect, better grades and were less likely to have risky behavior like taking drugs, smoking, or drinking．The findings, based on a national survey of nearly 12,000 middle and high school students, were published in a journal．

       "Across the board, children who engaged in any kind of activity were belier off than kids who watched a lot of TV," said study co author professor Penny Gordon Larsen of the University of North Carolina．

       Other studies have linked certain content of television programs, such as violence and sex, to children's behavior．But beyond this issue, Gordon-Larsen said that kids who spend hours watching TV "miss opportunities" to develop skills, learn teamwork and have other experiences that their more active peers benefit from．

       That doesn't mean, however, that kids have to be on the football team． The study found that some activities like skating and skateboarding——which adults sometimes frown upon——were also related to better self respect and less risk taking．

       That skaters were better behaved than TV watchers might come as a surprise to some adults who consider these teens to be bad, according to Gordon-Larsen．Skateboarding is forbidden in many public areas, and some communities oppose building skating parks．But if kids who like to skate have nowhere to do it, "it's a shame," said Gordon-Larsen．

       Not only should parents encourage their kids to engage iii the physical activities they enjoy, she said, but schools and communities should also do more to create opportunities for children to be active．
