The best way to reduce your weight
You hear this：“No Wonder you are fat.An you ever do is eat.”You feel sad：“I skip my breakfast and supper.I run every morning and evening.What else can I do?”Basically you can do nothing.Your genes，not your life habits，determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that，“80 percent of the Children of two obese parents become obese，as compared with no more than 14 percent of the offspring of two parents of normal weight.”
How can obese people become normal or even thin through dieting? Well，dieting can be effective.but the health costs are tremendous.Jules Hirsch，a research physician at Rockefeller University, did a study of eight fat people.They were given a liquid formula providing 600 calories a day1.After more than 10 weeks，the subjects lost 45kg on average.But after leaving the hospital，they all regained.The results were surprising：by metabolic measurement，fat people who lost large amounts of weight seemed like they were starving.They had psychiatric problems. They dreamed of food or breaking their diet2.They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn't result in normal weight，but in an abnormal state resembling that of starved non-obese people.
Thin people，however, suffer from the opposite：They have to make a great effort to gain weight.Ethan Sims，of the University of Vermont，got prisoners to volunteer to gain weight.In four to six months，they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended，they were back to normal weight and stayed there.
This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.
The findings also provide evidence for something scientists thought was true-each person has a comfortable weight range3.The range might be as much as 9kg.Someone might weigh 60-69 kg without too much effort But going above of below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.

答案與解析：
1.分析文章標(biāo)題：The best way(道路， 方法)to reduce (減少)your weight(重量，體重)
文章中會(huì)涉及到關(guān)于減少體重方法的介紹。
2.直接解題：
1. What determines(決定， 決心) your weight(體重)?
A)Your working(工作的， 運(yùn)轉(zhuǎn)的) manner(方式， 禮貌 ).
B)Your eating habit(習(xí)慣).
C)Your life style(生活方式).
D)Your genes(基因).
1.D. 細(xì)節(jié)題。利用被選項(xiàng)中的細(xì)節(jié)信息結(jié)構(gòu)(A：working manner; B: eating habit; C: life style; D: genes)共同作為答案線索， 在文章中查找答案相關(guān)句：
You hear this：“No Wonder you are fat.An you ever do is eat(選項(xiàng)B中eating的家族詞匯).”You feel sad：“I skip my breakfast and supper.I run every morning and evening.What else can I do?”Basically you can do nothing. Your genes(基因)，not your life habits(習(xí)慣)，determine your weight(問題句中的核心結(jié)構(gòu)) and your body constantly (不斷地，經(jīng)常地)tries to maintain(保持，維修， 主張) it.

They dreamed of food or breaking their diet2.They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn't result in normal weight，but in an abnormal state resembling that of starved non-obese people.
(第4段)Thin people，however, suffer from the opposite：They have to make a great effort to gain weight.Ethan Sims(問題句中的特征詞)，of the University of Vermont，got(說服，使, 變成， 獲得) prisoners(犯人) to volunteer to (自愿)gain weight(與選項(xiàng)B中的細(xì)節(jié)信息結(jié)構(gòu)呼應(yīng)).In four to six months，they ate as much as they could(盡可能地...).They succeeded in (成功地)increasing their weight(與選項(xiàng)B中的細(xì)節(jié)信息結(jié)構(gòu)呼應(yīng)) by(了) 20 to 25 percent.

5.A. 細(xì)節(jié)題。 利用問題句中的細(xì)節(jié)信息詞(Scientists)和備選項(xiàng)A和備選項(xiàng)B中的共有詞(weight range)共同作為答案線索， 在文章中查找答案相關(guān)句：
You hear this：“No Wonder you are fat.An you ever do is eat.”You feel sad：“I skip my breakfast and supper.I run every morning and evening.What else can I do?”Basically you can do nothing.Your genes，not your life habits，determine your weight and your body constantly tries to maintain it.
Albert Stunkard of the University of Pennsylvania found from experiments that，“80 percent of the Children of two obese parents become obese，as compared with no more than 14 percent of the offspring of two parents of normal weight.”
How can obese people become normal or even thin through dieting? Well，dieting can be effective.but the health costs are tremendous.Jules Hirsch，a research physician at Rockefeller University, did a study of eight fat people.They were given a liquid formula providing 600 calories a day1.After more than 10 weeks，the subjects lost 45kg on average.But after leaving the hospital，they all regained.The results were surprising：by metabolic measurement，fat people who lost large amounts of weight seemed like they were starving.They had psychiatric problems. They dreamed of food or breaking their diet2.They were anxious and depressed;some were suicidal.They hid food in their rooms.Researchers warn that it is possible that weight reduction doesn't result in normal weight，but in an abnormal state resembling that of starved non-obese people.
(第4段)Thin people，however, suffer from the opposite：They have to make a great effort to gain weight.(第4題答案相關(guān)句)Ethan Sims，of the University of Vermont，got prisoners to volunteer to gain weight.In four to six months，they ate as much as they could.They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended，they were back to normal weight and stayed there.
This did not mean that people are completely without hope in controlling their weight.It means that those who tend to be fat will have to constantly battle their genetic inheritance if they want to significantly lower their weight.
The findings (發(fā)現(xiàn))also provide(提供) evidence(證據(jù)， 跡象)for something scientists (科學(xué)家)thought was true (正確的， 真實(shí)的， 忠誠的) --- each person has a comfortable(舒適的) weight range .The range might be as much as(大約)9kg. Someone might weigh 60-69 kg without too much effort. But going above of below the natural weight range is difficult. The body resists by feeling hungry or full and changing the metabolism to push the weight back to the range it seeks.
答案相關(guān)句(最后一段的第一句話)說：結(jié)論還證實(shí)了科學(xué)家認(rèn)為是正確的一點(diǎn)，即每個(gè)人的體重有大約9公斤的一個(gè)固定范圍.因此A是答案。
