[1]Weighing too much can damage your health，and obesity is a growing problem for both kids and adults around the world．
[2]Sleep might be one answer to the problem．A new study has found that elementary school students who slept too little were more likely to gain pounds．
[3]Past studies have shown a link between sleeping less and weighing more，but scientists have had a tough time determining“which came first，the chicken or the egg，”says Julie C．Lumeng of the University of Michigan in Ann Arbor．
[4] In other words，it hasn't been clear whether kids who weigh too much have trouble sleeping，or whether leads to weight gain．Both scenarios Seemed equally possible．
[5] To get a better idea of which causes which，Lumeng and colleagues interviewed the parents of 785 third graders from around the United States．The parents answered questions about how well their kids slept that year．Three years later, the parents answered the same questions.
[6]By sixth grade，18 percent of kids involved in the study were obese．The scientists found no relationship between weight and the students’race or gender．It also didn't matter how strict their parents were，or whether they were boys or girls．Obesity struck all of these groups equally.
[7]Instead，sleep seemed to be the key factor．Over the 3 years of the study, the children averaged a healthy 9．5 hours of sleep a night．Some kids．however, slept a lot more—or less—than others.
[8]For the sixth graders，every hour of sleep above the 9．5-hour average was linked to a 20 percent lower risk of being obese．Sleep appeared doubly important for the third graders．Every extra hour of sleep they got was linked to a 40 percent drop in obesity by sixth grade．

[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch（门廊） and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.
[2] “Go fight somewhere else!” she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.
[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning（呻吟） in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.
[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(发抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.
[5]The Klevens then learned what had happened . Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.
