问题 单项选择题

一项调查研究表明.在普通人群中,与每晚睡眠时间保持在7至9小时的人相比,每晚睡眠时间少于4小时的人患肥胖症的危险高出73%,而平均每天只睡5小时的人,这种危险则高出50%。研究人员因此得出结论:缺乏睡眠容易使人变得肥胖。
以下各项如果为真。最能支持上述结论的是:

A.缺乏睡眠与糖尿病发病率上升存在关联.而大部分糖尿病患者都比较肥胖
B.缺乏睡眠容易导致慢性疲劳综合症。从而使人不愿意参加体育锻炼
C.睡眠不足者与每晚睡眠时间在7至9小时的人拥有同样的饮食和运动习惯
D.睡眠不足会导致人体内消脂蛋白浓度下降.而消脂蛋白具有抑制食欲的功能

答案

参考答案:C

解析: 题干由“睡眠时间越少,患肥胖症的危险系数越高”得出“缺乏睡眠容易使人变得肥胖”的结论。
A、B两项都从另外的角度解释了两者之间存在关联的原因,不能加强题干观点;C项排除了其他因素的影响,加强了题干结论;D项削弱了题干观点。故答案选C。

With the spread of inter-active electronic media a man alone in his own home will never have been so well placed to fill the inexplicable mental space between cradle and crematorium. So I suspect that books will be pushed more and more into those moments of travel or difficult defecation (1) people still don’t quite know what to do with.

When people do read, I think they’ll want to feel they are reading literature, or (2) something serious. (3) you’re going to find fewer books presenting themselves as no-nonsense and (4) assuming literary pretensions and being packaged as works of art.

In short, you can’t go too far wrong when predicting more of the same. But there is a (16) side to this—the inevitable reaction against it. The practical things I would like to see happen--publishers seeking less to (17) celebrity through extravagant advertising, (18) and magazines (19) space to reflective pieces—are rather more improbable than the Second Coming(耶稣复临). But dullness never quite darkens the whole planet. In their own idiosyncratic fashion a few writers will (20) be looking for new departures.
