答案與解析：
    1．分析文章標題：The best way（道路， 方法）to reduce （減少）your weight（重量，體重）
    文章中會涉及到關(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． 細節(jié)題。利用被選項中的細節(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.
    答案相關(guān)句說：你的基因而不是你的生活習(xí)慣決定了你的體重，因此你的身體總是試圖保持它。因此D是答案。
    2.What did Jules Hirsch do in his study(研究， 學(xué)習(xí)) ?
    A)He let the eight fat（肥胖的） people skip（跳躍，跳過） supper（晚餐）．
    B)He let the eight fat people skip breakfast．
    C)He let the eight fat people run（跑，管理） every morning（早晨） and evening（傍晚， 晚會）．
    D)He gave the eight fat people a liquid（液體的， 流動的， 液體） formula （配方， 公式）providing（提供） 600 calories（卡里路） a day．
    2. D。 細節(jié)題。利用問題句中的特征詞(Jules Hirsch)， 被選項中的共有結(jié)構(gòu)（eight fat people）及被選相中的一些細節(jié)信息詞及特征結(jié)構(gòu)（A: supper; B: breakfast; C: every morning and evening; D: liquid formula, 600 calories ）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．（第1題答案相關(guān)句）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（研究） physician（醫(yī)生）at Rockefeller University, did a study（研究） of eight fat people． They were given （被給）a liquid formula （流食配方）providing 600 calories a day1. After more than（超過） 10 weeks，the subjects(研究對象) lost 45kg on average（平均）．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．
    答案相關(guān)句說“八個肥胖者被給予一種流食配方，每天提供600熱卡”，因此D是答案。
