问题 What does the author think of the advice "eat less and exercise more"?
Which factor is mentioned in paragraph 2?
选项 A、Too much sleep may increase one’s weight.
B、Lack of sleep may be one of the reasons causing the overweight problem.
C、9 hours of sleep is perfect for people to stay slim.
D、Less than 7 hours of sleep will increase the danger of gaining extra pounds.
答案B
解析 考查细节。题干明确告诉我们出题处在原文的第二段，结合选项都在讨论“sleep’’相关的话题这一特征，我们找到第二段进行对比阅读，我们可以发现，原文提到“人们的平均睡眠时间从9小时开始缩减到了小时，睡眠的不足是导致肥胖的部分原因”，与这一点含义相同的选项是B；A项正好与这一信息相反，C项和D项把原文对于人们睡眠减少这一现象的描述进行了泛化的推论，原文只是用数字来描述这一问题，并没有对这些数字表示的具体含义进行说明，C项和D项都脱离原文进行了各自的阐述，都属于干扰选项，需要排除。
