17.Werewolves (狼人) aren't the only creatures affected by the moon's cycles(周期).A full moon also affects people's sleep more or less,reports a Swiss team of scientists.Even people who sleep in a lab without windows could reduce their sleeping time a little once a month.To test the moon's influence,33adults of both sexes and ages of many kinds spent several nights in a sleep lab.As they slept,researchers recorded their brain activity,eye movements and hormone levels (荷尔蒙水平).On nights closer to a full moon,the sleepers took an average of five minutes longer to fall asleep,and slept for 20minutes less.In addition,brain activity fell by 30percent during the sleep.And hormone levels that help control sleep cycles went down.On these nights,the sleepers complained they couldn't sleep well even though they didn't know the moon's cycle.On the bright side,no sleeper turned into a werewolf.
The Swiss team doesn't know how the moon affects sleep.The gravity (重力) of the moon causes ocean tides(潮汐)to rise and fall.But that force is too weak to affect sleep,Gajochen says.He believed some body's biological clock may be affected by the moon cycles.There may be another reason,says David Dinges.This sleep researcher at the University Of Pennsylvania in Philadelphia says that the body clock is very sensitive(敏感的)to light at night.Those sleepers could have been affected by having too much moonlight before arriving at the lab.

分析 本文主要讲述了一个关于月亮影响人的睡眠的实验,实验得出月亮会影响人的睡眠,尤其是在满月的时候.
解答 24.B 推理判断题.根据前文可知,文章开头引入狼人的故事主要是为了抓住人们的眼球,吸引更多读者去阅读,故选B.
25.C 细节理解题.根据第二段中In addition,brain activity fell by 30 percent during the sleep.可知,满月的时候大脑的活跃程度降低30%,故选C.
26.A细节理解题.最后一段主要讲述了科学家们对于这一事件的解释,故选A.
27.C 主旨大意题.纵观全文,本文主要讲述了月亮也会对人的失眠造成一定的影响.故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
