Like a needle climbing up a bathroom scale, the number keeps rising. In 1991, 15% of Americans were obese(肥胖的); by 1999, that proportion had grown to 27%. Youngsters, who should have age and activity on their side, are growing larger as well: 19% of Americans under 17 are obese. Waistbands have been popping in other western countries too, as physical activity has declined and diets have expanded. 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 and famine. But, according to research presented at the annual meeting of the American Association for the Advancement of Science, it is more a case of being out of the frying pan and into the fire. The most striking example actually in the poor world comes from the Pacific islands, home of the world’s most obese communities. In 1966, 14% of the men on this island were 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 single household. A study of families in Indonesia found that nearly 10% contained both the hungry and the fat. This is a mysterious phenomenon, but might have something to do with people of different ages being given different amounts of food to eat.
The prospect of heading off these problems is bleak. In many affected countries there are cultural factorsto contend with, such as an emphasis on eating large meals together, or on food as a form. of hospitality.Moreover, there is a good measure of disbelief on the part of policymakers that such a problem Could existin their countries. Add to that reluctance on the part of governments to spend resources on promoting dietand exercise while starvation is still a real threat, and the result is a recipe for inaction. Unless something is done soon, it might not be possible to turn the clock back.

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。
It happens to every medical student sooner or later. You get a cough that persists for a while. Ordinarily,you would just ignore it--but now, armed with your rapidly growing medical knowledge, you can’t help worrying. The cough could mean just a cold, but it could also be a sign of lung cancer.
For doctors in training, nurses and medical journalists, hypochondria is an occupational danger. The feeling usually passes after a while, leaving only a funny story to tell at a dinner party. But for the tens ofthousands who suffer from true hypochondria they live in constant terror that they are dying of some awfuldisease, or even several awful diseases at once. Doctors can assure them that there’s nothing wrong, but since the cough is real, the assurances fall on deaf ears. And because no physician or test can offer a 100% guarantee that one doesn’t have cancer, a hypochondriac always has fuel to feed Iris .or her worst fears.
Hypochondriacs don’t harm just themselves; they block the whole healthcare system. Although they account for only about 6% of the patients who visit doctors every year, they tend to burden their physicians with frequent visits that take up excessive amounts of time. And the problem may be worse, thanks to the popularity of medical information on the Internet. They go on the Web and learn about new diseases and new presentations of old diseases that they never even knew about before. Doctors have taken to calling this phenomenon cyberchondria (网络疑病症).
Choose correct answers to the question:
1.According to the passage, if you suffer from hypochondria, ______.
A.you must be a medical student, or a medical worker
B.you are haunted by a possibly inexistent disease
C.you will never get rid of this disease
D.you always tell funny stories at dinner parties
2.Which of the following best summarizes the main idea of the passage?
A.Hypochondria happens to everybody sooner or later.
B.We needn’t worry about hypochondria since it is not dangerous at all.
C.Hypochondria originates from too much knowledge of medicine.
D.Not only individuals but also the healthcare system might be disturbed by unnecessary terrors.
3.Why can’t doctors convince the suffers that there is nothing wrong?
A.Because the doctors can’t cure the minor diseases
B.Because the doctors don’t assure them of that
C.Because the sufferers are deaf and cannot hear what the doctors say
D.Because lack of absolute guarantee makes the patients doubtful
4.The problem becomes worse due to _____
A.the increasing number of patients
B.the widespread medical knowledge on the Internet
C.the patients,regular visits to doctors that occupy too much time
D.new diseases and symptoms emerge constantly
5.What does the author most probably think about hypochondria?
A.The author considers that hypochondria is an incurable disease
B.The author thinks that the consequences of hypochondria might be disastrous
C.The author suggests that the patients who have hypochondria should set their hearts at rest
D.The author sympathizes with the patients who suffer from hypochondria
1.[B] 事实细节题。仔细读完第2段后半部分,不难发现hypochondria只是瞎猜疑，故选项B正确。时常怀疑自己生病是医务人员的职业病，但为此困扰的并不仅仅是他们，因为第2段第3句说：“But... who suffer from true hypochondria...”，说明医务人员不是真正的疑病症患者,故选项A不正确。选项C过于极端。选项D是对原文断章取义。
3.[D] 事实细节题。根据文中的“because no physician or test can offer a 100% guarantee that one doesn’t have cancer...”即可得出选项D正确。原文虽有表示“咳嗽确实存在”，但这并不意味着医生不能治好类似的小毛病，因此选项A不正确。误选C是没有正确理解短语fall on deaf ears,该固定表达的意思是“充耳不闻”。
4.[B] 推理判断题。句中thanks to是讽刺的用法，引出原因，故选项B正确。本题考查因果关系，要辨别明显的因果关系，只要关注文中是否有because, reason, due to, thanks to, result等词即可。
