Like a needle climbing up a bathroom scale, thenumber keeps rising. In 1991, 15% of Americanswere obese(肥胖的); by 1999, that proportion hadgrown to 27%. Youngsters, who should have age andactivity on their side, are growing larger as well: 19% of Americans under 17 are obese. Waistbandshave been popping in other western countries too, asphysical activity has declined and diets haveexpanded. By and large, people in the rich world seem to have lost the fight against flab(松弛).

Meanwhile, poorer nations have enjoyed some success in their battles against malnutrition andfamine. But, according to research presented at the annual meeting of the AmericanAssociation for the Advancement of Science, it is more a case of being out of the frying pan andinto the fire. The most striking example actually in the poor world comes from the Pacificislands, home of the world's most obese communities. In 1966, 14% of the men on this islandwere obese while 100% of men under the age of 30 in 1996 were obese.

This increase in weight has been uneven as well as fast. As a result, undernourished and over-nourished people frequently live cheek by jowl(面颊). The mix can even occur within a singlehousehold. A study of families in Indonesia found that nearly 10% contained both the hungryand the fat. This is a mysterious phenomenon, but might have something to do with peopleof different ages being given different amounts of food to eat.

The prospect of heading off these problems is bleak. In many affected countries there arecultural factorsto contend with, such as an emphasis on eating large meals together, or onfood as a form. of over, there is a good measure of disbelief on the part ofpolicymakers that such a problem Could existin their countries. Add to that reluctance on thepart of governments to spend resources on promoting dietand exercise while starvation is stilla real threat, and the result is a recipe for inaction. Unless something is done soon, it mightnot be possible to turn the clock back.

　　参考答案

1.[B] 推理判断题。根据第1段第2句可推断第1句中的the number是指体重增加的人数，故答案为B。

2.[B] 推理判断题。本题需要正确理解借代修饰手法。Waistbands have been popping形象刻画出其他西方社会急剧肥胖化的过程，故答案为B。本题很明显是考查因果关系的，第1段倒数第2句明确指出这个因果关系，只要根据该句做出选择就可以了。如果看得过远,反而有可能误选A或D。

3.[A] 事实细节题。此处的例子是证明前一句话的，即But后面的内容。同时，两个年份的比较也突出问题发展的迅猛，从而印证下一段的主题句“This increase in weight has been uneven as well as fast.”说明了贫穷与肥胖是并存的。例子一般是用来证明紧挨着的前面或后面的论述，此处证明的观点在之前，其中的`重点应该是But后面的内容，所以选项A与文中意思不符。注意本题要选的是NOT the point of the example。

4.[D] 观点态度题。文章最后一句扭转了整段的基调。作者呼吁解决这一问题，前文正是为此作铺垫，突出问题的复杂性和时间的紧迫性。

5.[A] 主旨大意题。本文话题为obesity，作者从美国谈到所有西方国家，最后重点讨论其在发展中国家的最新发展趋势以及种种可能的成因，并强调应当尽早解决问题，故选项A正确。肥胖问题的阵营没有转移，只是扩大了，故选项D不对。选项B只是片面信息，没有包括最后一段关于如何解决肥胖问题的内容。选项C中的starvation并非本文讨论的主要话题。
