{{B}}Losing Weight{{/B}}
Girls as young as 10 years old are dieting and in danger of developing unhealthy attitudes about weight, body image and food, a group of Toronto researchers reported Tuesday.
Their study of 2,279 girls aged 10 to 14 showed that while the vast majority had healthy weights, nearly a third felt they were overweight and were trying to lose pounds. Even at the tender ages of 10, nearly 32 per cent of girls felt "too fat" and 31 per cent said they were trying to diet.
McVey, a researcher at the Hospital for Sick Children in Toronto, and her colleagues analyzed dam collected in a number of surveys of southern Ontario school girls between 1993 and 2003, reporting their findings in Tuesday's issue of the Canadian Medical Association Journal.
Nearly 80 per cent of the girls had a healthy body weight and only 7.2 per cent were considered overweight using standard weight-to height ratios. Most researchers suggest the rate of overweight children in this country is several times higher than that figure.
Nearly 30 per cent of the girls reported they Were currently trying to lose weight, though few admitted to dangerous behavior such as self-induced vomiting.
Still, a test that measured attitudes towards eating showed 10.5 per cent of survey Participants
were already at risk of developing an eating disorder.
"We're not talking about kids who've been prescribed a diet because they're above average weight or overweight. We're talking about children who are within a healthy weight range. And they have taken it upon themselves to diet to lose weight," McVey said, acknowledging she found the rates disturbing. She said striking a balance between healthy weights and healthy attitudes towards food and body image is a complex task, with no easy solutions.
overweight adj. 超重的，过重的
induce vt.引起，导致
prescribe vt.处方;开药;嘱咐

单选题 What kind of institution does the lead researcher work with?

【正确答案】 B

【答案解析】[解析] 问题问“主要的那个研究者(researcher是单数)在哪个机构下作”，利用题干中的核心结构institution和lead researcher作为答案线索，这样发现文章中并没有这两个词出现，所以判断可能需要考生进行推断。文章中具体提到的单个的研究者就是Mc Vey(MeVey，a researcher at thehospital for sick children in Toronto(一家儿童医院的研究者)，and her colleagues analyzed date collected in a number Of Surveys of southern Ontario schoolgirls between 1993 and 2003，reporting their findings in Tuesday's iSSUe of the Canadian Medical Association Journal．)而文章的结尾也是以McVey的观点/看法结尾：(McVey said， acknowledging she found the rates disturbing．She said…)因此判断Mc Vey就是题干中提到的“主要研究者”，并判断B是答案。

单选题 Unhealthy attitudes about weight, body image and food may ______.

【正确答案】 A

【答案解析】[解析] 利用备选项的内容发现答案相关句：(注意到下面的句子是因为它涉及到了备选项A的内容)Still，a test that measured auitudes towards eating showed l0．5 percent of survey participants were already at risk of developing an eating disorder(A也出现了eating disorder)．现在需要参考上一句判断10．5 percent of survey participants与题干中的"Unhealthy attitudes"之间的关系：Nearly 30%of the gifts reported they were currently trying to lose weight，though few few admitted to dangerous behavior such as self-induced vomiting．根据该句的内容可以判断答案相关句中的提到的"10．5 percent of survey participants"是指“试图减肥的女孩”，而文章一开始就说"Gifts as young m 10 years old are dieting and in danger of developing unhealthy attitudes about weight，body image and food a group of Toronto resea rchers reported today．'’(小到年纪只有10岁的女孩在节食，在形成刘‘体重和体形食物的不健康的认识，而这些认识是很危险的。)这句话的内容暗示“那些节食的女孩”持有“不健康的饮食态度”，综合上面的分析判断A是答案。
