单选题 As a father to three young girls, I have been particularly struck over the past several months by the flurry of public activity related to childhood obesity . While the efforts are well-intentioned, it"s worrisome to watch the movement gain momentum when we still don"t really know whether what we"re doing is actually working — nor do we really know if there will be any downsides to the anti-obesity initiative. The most recent major move in the fight against childhood obesity came on Jan. 25 when First Lady Michelle Obama announced that school meal options were going to get a lot healthier. It is, undoubtedly, a good idea to make school lunches more nutritious, although some research suggests that by the time a child gets to school, his or her tastes for high calorie or otherwise unhealthy food is already in place and that changing lunch doesn"t make them eat healthier at home. In other words, school-based initiatives may be too little too late for those children who may be predisposed, whether through genetics or environment or both, towards obesity .
According to the Centers for Disease Control, 17% of all children and adolescents in the U.S. are obese. Yet the majority of obesity programming, especially in our schools, is applied to the child and adolescent populations as a whole. Sure, promoting healthy eating, regardless of one"s weight or age, seems like a positive thing on the surface. But here"s the potential downside : We know kids and teens react differently than adults to external pressures like persistent messaging. Sometimes these pressures can translate into incredible waves of anxiety and fear. At the extreme, a healthy-weight youth could be pushed to monitor his weight more frequently or even begin an unsupervised diet — behaviors that might represent an impending eating disorder.
So the real question is what are children saying and how are they behaving in light of our anti-obesity effort? A nationally representative survey, conducted last September by the C. S. Mott Children"s Hospital National Poll on Children"s Health, attempted to answer this question. The results, released in January, showed that 30% of parents of children age 6-14 report worrisome eating behaviors and physical activity in their children; 17% of parents report that their children are worried about their weight; 7% say their children have been made to feel bad at school about what or how much they were eating; and 3% of parents report their children had a sudden interest in vegetarianism. Certainly these data do not directly link the anti-obesity effort and eating disorders. They also do not offer any insight into whether obese children are actually losing weight. They do, however, serve as a reminder of how vulnerable these "worried" children already are to disordered eating and that everything we do, no matter how well-placed our intent carries risk .
With that said, we shouldn"t stop promoting healthy eating habits in our children. And we shouldn"t necessarily downplay our anti-obesity efforts for fear of increasing the rate of childhood eating disorders. Instead, we should just be mindful — with their wonderful and special abilities as well as their unpredictabilities, children surely deserve an approach and awareness that is as well-thought out and balanced as the meals we"d like them to eat.

单选题 Michelle Obama"s proposal concerning school meals meets with some controversy because ______.

【正确答案】 B

【答案解析】细节事实题
[解析] 本题主要是考查对文章第一段内容的理解。第一夫人米歇尔·奥巴马提出要改善校园午餐的营养结构，以改善美国儿童肥胖的现象。但是，她的这一提议引发了争议。争议的焦点在于改善校园午餐结构到底能不能改善儿童肥胖现象。有研究表明，等孩子入学时，他们对高热量食品及其他垃圾食品的偏好已成定局，改变午餐搭配并不会让他们在家的饮食变得更健康。因此，符合原文意思的答案应该是[B]。[A]属无关信息干扰，第一段并没有提到人们对于校园午餐营养标准的争议。[C]是关于父母在儿童过量饮食方面扮演的角色的争议，而不是对于米歇尔提议的争议。[D]利用第一段最后的predisposed、genetics等词设置干扰。第一段最后一句话的含义是，改变学校午餐搭配对于那些已经由于基因或环境原因产生肥胖倾向的孩子起不到什么作用。很明显，人们认为肥胖是由基因或环境，或者两者共同决定的，而不是单独由基因决定。

单选题 We know from Paragraph 2 that the major concern of the author is that ______.

【正确答案】 D

【答案解析】作者观点题
[解析] 本题考查作者要表达的主要论点。作者在第二段中提到，青少年减肥势在必行。但是孩子和青少年可能会在长期的信息灌输下产生成年人不大可能产生的精神压力，而这种压力可能导致焦虑和恐惧。因此，作者主要关注的是减肥项目可能给儿童带来的心理上的伤害，以及由此产生的生理上的伤害。最准确的答案是[D]。[A]和第二段整个论述的内容毫无关系。[B]虽然是第二段最后一句话中提到的内容，但是注意，作者只是将正常体重的儿童患上饮食紊乱症作为一种极端案例提出，其目的还是为了凸显饮食计划对于儿童整体的身心上可能造成的伤害。[C]错在malnutrition一词，作者担心的并不是儿童可能因为减肥项目营养不良，而是因为减肥项目心理受到伤害。

单选题 The survey conducted by the C. S. Mott Children"s Hospital National Poll on Children"s Health indicates that______.

【正确答案】 D

【答案解析】细节事实题
[解析] 第三段作者用一份研究调查报告证明自己的担忧。C．S．莫特儿童医院全国调查就儿童健康问题展开了一次全国范围的典型性调查。结果表明，6至14岁儿童的家长中，有30%的人表示孩子的饮食习惯和体育活动状况令人忧虑，而不像[A]中所说，已经有30%的儿童患上饮食紊乱症。[A]偷换概念。作者在第三段中还明确提到，这些数据结果并不能证明抵抗肥胖运动和饮食失调之间存在直接关联，因此[B]错误。[C]并不是报告关注的主要内容，虽然报告主要是针对儿童家长展开的，家长们也就儿童表现出的饮食倾向做出了回答，但是孩子面对饮食紊乱很脆弱问题并不是调查的目的。[D]为正确答案，调查唯一能够明确显示的就是儿童们正面临着饮食紊乱的风险，如果再不引起重视，这种风险可能就会转化为无法挽回的后果。
