Which of the following is NOT mentioned in the passage? [br]
(14)Weighing too much can damage one’s health and obesity is a growing problem for both kids and adults around the world. Sleep might be one answer to the cause of the problem.(17-1)A new study has found that elementary school students who slept too little were more likely to gain weight. 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".(15-1)In other words, it hasn’t been clear whether kids who weigh too much have trouble sleeping, or whether sleeping less leads to weight gain. Both cases seemed equally possible.(15-2)To get a better idea of which causes which, the researchers interviewed the parents of 785 third graders from around the country. The parents answered questions about how well their kids slept that year. Three years later, the parents answered the same questions. By the sixth grade, 18 percent of kids involved in the study were fat.(17-2)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. Even so, sleep seemed to be the key factor.(16)Over the 3 years of the study, the children averaged a healthy 9 hours of sleep a night. Some kids, however, slept a lot more—or less—than others.
选项
A、find out why some children find it difficult to go to sleep
B、learn more about the link between sleep and weight
C、identify the ways parents reduce their kids’ weight
D、see if there is difference in sleep patterns over the period
答案
B
解析
细节题。根据“In other words,it hasn’t been clear whether kids who weigh toomuch have trouble sleeping,or whether sleeping less leads to weight gain.”和“To get a better idea of which causes which.the researchers interviewed theparents of 785 third graders from around the country.”可知,为时三年的研究主要是为了弄清楚究竟是睡眠少导致肥胖,还是肥胖导致睡眠不足,即该研究的主要目的是了解睡眠与肥胖之间的关系,因此[B]为答案。
