.  Children are getting so fat they may be the first generation to die before their parents, an expert claimed yesterday. Today's youngsters are already falling prey to potential killers such as diabetes because of their weight. Fatty fast-food diets combined with sedentary lifestyles dominated by televisions and computers could mean kids will die tragically young, says Professor Andrew Prentice, from the London School of Hygiene and Tropical Medicine.
    At the same time, the shape of the human body is going through a huge evolutionary shift because adults are getting so fat. Here in Britain, latest research shows that the average waist size for a man is 36-38 in and may be 42-44 in by 2032. This compares with only 32.6 in 1972. Women's waists have grown from an average of 22 inches in 1920 to 24 inches in the Fifties and 30 inches now. One of the major reasons why children now are at greater risk is that we are getting fatter younger. In the UK alone, more than one million under 16s are classed as overweight or obese—double the number in the mid-Eighties. One in ten four-year-olds are also medically classified as obese. The obesity pandemic—an extensive epidemic—which started in the U.S., has now spread to Europe, Australia, Central America and the Middle East. Many nations now record more than 20 percent of their population as clinically obese and well over half the population as overweight. Prof Prentice said the change in our shape has been caused by a glut of easily available high-energy foods combined with a dramatic drop in the energy we use as a result of technology developments.
    He is not alone in his concern. Only last week one medical journal revealed how obesity was fueling a rise in cancer cases. Obesity also increases the risk factor for strokes and heart disease. An averagely obese person's lifespan is shortened by around nine years while a severely obese person by many more.
    Prof Prentice said: "So will parents outlive their children, as claimed recently by an American obesity specialist?" The answer is yes—and no. Yes, when the offspring becomes grossly obese. This is now becoming an alarmingly common occurrence in the U.S.. Such children and adolescents have a greatly reduced quality of life in terms of both their physical and psychosocial health. So say No to that doughnut and burger.1.  What does the word "sedentary (Para.1)" mean? ______
【正确答案】 A
【答案解析】 本文主要说明了美国的一个主要问题是年轻人的肥胖问题。这一代的年轻人比上一代人要更胖,并且在更年轻的时候发胖。这会造成年轻人的健康问题。
   释义题。题目问的是“sedentary”一词的含义。定位到第一段“Fatty fast-food diets combined with sedentary lifestyles dominated by televisions and computers could mean kids will die tragically young”,意为“脂肪含量过高的快餐饮食,加上电视和电脑使得孩子们养成了sedentary的生活方式,极有可能大大缩短年轻一代的寿命”,“电视和电脑”是养成孩子们sedentary的生活方式的原因,由此可见,sedentary指“久坐不动”。故选A。
[参考译文] 专家昨日声称,这些不断变胖的孩子们可能是让他们的父母白发人送黑发人的第一代。因为体重的原因,现在的年轻人已经成为隐形杀手如糖尿病的目标了。来自伦敦大学卫生和热带医学院的安得烈普·伦提斯教授说脂肪含量过高的快餐饮食,加上电视和电脑使得孩子们养成了久坐不动的生活方式,极有可能大大缩短年轻一代的寿命。
   在同一时间,人的体型也在进行一个巨大的进化转变,因为成年人越来越胖。在英国,最新的研究表明,男性的平均腰围是36-38英寸和到2032年可能达到42-44英寸。与此相比,1972年的平均腰围只有32.6英寸。女性的腰围已经从1920年代的平均22英寸到50年代的24英寸和现在的30英寸。现在孩子们面临更大风险的主要原因之一是我们变胖的年龄段越来越年轻化。仅仅在英国,就有100多万16岁以下的儿童被归为超重或者肥胖,比80年代中期多了一倍。在4岁的青少年中,1%的孩子在医学上被归类为肥胖。肥胖在美国开始流行,现在已蔓延到欧洲、澳大利亚、美国中部和中东地区。现在,许多国家的人口超过20%的被定义为肥胖,而超过一半的人口超重。普伦提斯教授说,导致我们体形变化的原因是,现代生活中高热量食物随处可见,随手可得,而科技的发展使得人们每天消耗的热量却大大减少。
   他的这一观点得到了其他人的认可。上周一个医学杂志揭示了肥胖是如何助长癌症病例增长的。肥胖也增加中风和心脏病的风险。一个中等肥胖者的寿命缩短9年左右,而严重肥胖者则更严重。
   普伦提斯教授说:“最近的美国肥胖专家发问,父母会活得比他们的孩子久吗?”答案是肯定的也是否定的。但当子孙后代变得非常肥胖时,答案是肯定的。这现在在美国成为一个惊人的普遍现象。就青少年的生理和心理健康而言,他们的生活质量大大降低了。所以,就让我们向甜甜圈和汉堡包说“不”吧!
