Going hungry is a major contributor to ill health, particularly among children, and a new report reveals how long-lasting the damage can be. Researchers at the National Cancer Institute (NCI) and the University of Calgary performed the first longterm study on the【C1】______of hunger on general health,【C2】______children from birth to 21 years. Most studies to date have【C3】______only snapshots of childhood health,【C4】______the short-term impact of hunger【C5】______a period of time. In the new analysis, the scientists found that children who went hungry at least once in their lives were 2i-times more likely to have【C6】______overall health 10 to 15 years later, compared with those who never had to【C7】______food. 'Our research shows that hunger and food insecurity are really damaging【C8】______childrens life chances,' says lead author Sharon Kirkpatrick, a visiting fellow at NCI. The study supports earlier findings that【C9】______episodes of hunger are more likely to cause ill health than an isolated experience of starvation: children in Kirkpatricks analysis who experienced two or more periods of hunger were more than four times as likely to report ill health than those who never went hungry. The relationship, she says, remained strong even after the team accounted【C10】______other factors that could influence health, such as age, sex and household characteristics like income. 【C11】______one experience of hunger can have lasting effects on a childs health, a fact that is especially troubling in light of the sobering rise in U.S. households that were【C12】______to do without food in 2008: 15% of American families reported some【C13】______in the amount or quality of food they consumed,【C14】______from 11% the previous year. 15 this study did not probe into the【C16】______mechanism by which hunger affects long-term health, Kirkpatrick【C17】______that both psychological and physiological factors may be at work. Aside from the obvious negative impact that missing key nutrients and calories can have on growth and development, she says, the psychological【C18】______of food insecurity—not being able to afford a【C19】______and high-quality source of food—can be【C20】______to youngsters as well.

未知题型 Everyone knows that the first rule of driving is never taking your eyes off the road. Teen drivers【C1】______being careful, but they tend to start multitasking after just a few months behind the wheel, according to research published Tuesday. And【C2】______older drivers can handle eating or talking to passengers, which【C3】______up the new drivers, dialing a cell phone increased the risk of accidents among young and【C4】______drivers alike. This isnt great news, since its well【C5】______that distracted driving is a leading cause of accidents among all drivers. It makes sense that young drivers will start testing their limits after a few months behind the wheel, according to Bruce Simons-Morton, a behavioral scientist. 'You increase the difficulty of a task until you make an【C6】______,' Simons-Morton says. 'It seems like a very natural thing but still its very【C7】______, because good driving ability and safety judgment develops【C8】______a very long period of time.' Within six months of getting their licenses, young drivers in this study -started texting, eating and【C9】______the radio while driving as much as their more skilled【C10】______But it takes thousands of hours of【C11】______to get good at driving, according to Simons-Morton. That disconnect may help【C12】______the high accident rates among teenage drivers. The researchers compared data from two small studies—one tracked 42【C13】______licensed young drivers and the other looked at 100 drivers with more experience . All the participants had sensors and cameras【C14】______in their cars. The researchers used the sensors to track when drivers got into accidents or close calls. The videos were then used to see what the drivers were doing just before the accidents【C15】______. Because the researchers wanted to focus on the【C16】______of distracted driving, they【C17】______crashes caused by drunk driving and ones that were clearly caused by other drivers. Since the number of people in this study was small, Simons-Morton says the results will have to be【C18】______by other research. A couple of bigger studies already【C19】______the works, might make things clearer. But Simons-Morton says this is the first totally【C20】______look at teen driver distraction.【C1】A．start overB．start forC．start offD．come off
