题目内容
3．Can you fall fast asleep at night？If not，you can try to drink a glass of hot milk．（36）E Still no luck？Try thinking about sheep jumping over a fence．Count them to yourself，"One，two，three，four…one hundred and ninety-five，one hundred and ninety-six…"（37）C Should you take a sleeping pill？People who take pills often come to depend on the drugs．So you lie awake knowing that the new work day will soon arrive．If this happens to you forat least one month，you may have primary insomnia（失眠）．There are millions of you…us…around the world．
A new study has found that you might fall asleep quicker and stay asleep longer if you try"cerebral hypothermia"．No，cerebral hypothermia is not a complex medical process．（38）B
Two American professors led the study．They examined 12people who had insomnia and 12others who had no sleep problems．Each of them wore a soft plastic cap on their heads at bed time．
（39）D The researchers moved the water through the tubes and then changed the temperature of the water．Other studies showed that people who had trouble sleeping often had more chemical reactions in the front of their brains．The researchers thought lowering the temperature of the brain might help．
The first two nights of testing，the patients wore no water caps．During the next two nights，the caps were worn，but the water was not cooled．Then the researchers cooled the water a little for two nights．（40）G
The researchers found that the water caps did not help the insomnia patients until the temperature was about 14℃．Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads．
A．Some say sheep counting might help．
B．It just means cooling down your brain．
C．It is late at night and you are still awake．
D．The caps had tubes inside filled with water．
E．If that does not work，listen to some soft，beautiful music．
F．They believe they have discovered something important that needs more research．
G．On the final two nights of the study，the temperature of the water was made much cooler．
分析 本文为说明文，介绍了一种名为"大脑降温"的治疗失眠的方法．即戴着装有水管的帽子，通过冷却水管来降低大脑的温度，从而促进睡眠．
解答 36-40 E C B D G
36．E 考查上下文理解判断能力．根据上文If not，you can try to drink a glass of hot milk可知，如果睡不着，喝一杯热牛奶，下文应是：如果这还不起作用，听柔和的优美的音乐．故选E．
37．C 考查上下文理解判断能力．根据下文Should you take a sleeping pill可知，要不要吃一片安眠药呢，上文应是：如果很晚了，仍然睡不着．故选C．
38．B 考查上下文理解判断能力．根据上文cerebral hypothermia is not a complex medical process可知，大脑降温并不是一个很复杂的事情，接下来就开始解释它是什么，即：它意味着冷却你的大脑．故选B．
39．D 考查上下文理解判断能力．根据上文Each of them wore a soft plastic cap on their heads at bed time可知，他们每个人在睡觉时头上戴一个软的塑料帽，下文应是涉及到帽子，下文应是：这些帽子里是有水管的．故选D．
40．G 考查上下文理解判断能力．根据上文The first two nights of testing，the patients wore no water caps．During the next two nights，the caps were worn，but the water was not cooled．Then the researchers cooled the water a little for two nights可知，头两晚没戴帽，接着两晚戴帽，但水没冷却，又两晚水冷却，下文应是：再两晚，水冷却得更冷．故选G．
点评 七选五题型看似简单，实际上有时完全作对并不容易，需要方法和分析能力及足够的耐力，有必要进行专门练习．首先，快速浏览一遍七个备选答案，先确定哪个选项适合放在文章的什么位置．其次，快速浏览文章，确定文章体裁，抓住文章结构，分析篇章结构，找出各段的主题句或主旨大意．其三，注意各选项中出现的句子衔接手段，寻找句中衔接标志词，七选五备选答案中有两个多余的选项，会对文章中两个空的选择构成干扰，这时要特别细致地比对相似选项．最后，用代入法，检查答案是否合理，将所有选择答案放回空白处，通读全文，检查文章内容是否语义连贯合理、紧扣主题，语篇结构是否通顺连贯、具有一致性、合乎逻辑，写作思路是否清晰明了，格式以及用语是否恰当贴切，从而判断选择的答案是否正确．
