47. What is the popular view of obesity?
- A. It is difficult to define.
- B. It is a modern disease.
- C. It has much to do with one's genes.
- D. It results from a lack of self-control.
答案：D
答案句：Yet the widespread view is that obesity is self-induced and that it is entirely the individual's responsibility to do something about it.
参考译文：然而，普遍的观点是，肥胖是自我诱发的，完全是个人的责任去采取行动。
定位线索：题干“popular view”→答案句“widespread view”；文中“self-induced”、“entirely the individual's responsibility”对应选项D“lack of self-control”（缺乏自控）。
解析：题干问大众对肥胖的普遍看法。答案句中的“widespread view”即题干“popular view”，指出大众认为肥胖是自我诱发、完全由个人负责，即源于缺乏自控，对应D项。A项“难以定义”是理查德·派尔的观点，B项“现代疾病”未提及，C项“与基因有关”是怀尔丁的观点，均答非所问。
49. What does Dr. Richard Pile think of the dictionary definition of disease?
- A. It is of no use in understanding obesity.
- B. It is too inclusive and thus lacks clarity.
- C. It helps little to solve patients' problems.
- D. It matters little to the debate over obesity.
答案：B
答案句：He believes that the dictionary definition of disease “is so vague that we can classify almost anything as a disease” and says the question is not whether we can, but whether we should, and to what end.
参考译文：他认为疾病的词典定义“太模糊了，以至于我们几乎可以把任何东西都归类为疾病”，并说问题不在于我们能否这样做，而在于我们是否应该这样做，以及要达到什么目的。
定位线索：题干“Dr. Richard Pile think of the dictionary definition”→答案句“He believes that the dictionary definition of disease”；文中“so vague”、“classify almost anything”对应选项B“too inclusive and thus lacks clarity”（过于宽泛而缺乏清晰度）。
解析：题干问理查德·派尔博士对疾病词典定义的看法。答案句中他明确说定义“太模糊”，几乎任何东西都能被归类为疾病，即定义过于宽泛、缺乏明确性，对应B项。A项“对理解肥胖无用”未提及，C项“无助于解决问题”未提及，D项“对争论无关紧要”与原文相反（他认为这很重要），均属无中生有或偷换概念。
