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 (荷爾蒙水平).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 本文主要講述了一個(gè)關(guān)于月亮影響人的睡眠的實(shí)驗(yàn),實(shí)驗(yàn)得出月亮?xí)绊懭说乃,尤其是在滿月的時(shí)候.
解答 24.B 推理判斷題.根據(jù)前文可知,文章開頭引入狼人的故事主要是為了抓住人們的眼球,吸引更多讀者去閱讀,故選B.
25.C 細(xì)節(jié)理解題.根據(jù)第二段中In addition,brain activity fell by 30 percent during the sleep.可知,滿月的時(shí)候大腦的活躍程度降低30%,故選C.
26.A細(xì)節(jié)理解題.最后一段主要講述了科學(xué)家們對(duì)于這一事件的解釋,故選A.
27.C 主旨大意題.縱觀全文,本文主要講述了月亮也會(huì)對(duì)人的失眠造成一定的影響.故選C.
點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
