Lack of Sleep Is Dangerous
Do you know that if you miss out too much sleep you will die? It’s true! If you stay awake for a long, long time, your brain and body will break down.
The unofficial world record for staying awake is 11 days, and it’s held by Randy Gardner.
1 He also had help from TV and radio reporters, a sleep researcher and a doctor.
What happened?
2 Then his brain started to lose sense. On day 4, he thought a street sign was really a person. On day 6, he began to speak very slowly. On day 9, he couldn’t finish sentences. On day 10，Randy thought he saw a forest in the next room.
3 Eventually, after he’d broken the world record, Randy was told to go to sleep. Experiments that keep people awake for dangerously long periods are always stopped before the patients break down.
Rats, however, aren’t so well cared for.
4 That’s sooner than if they’d been allowed to sleep but were given no food. They get really thin. But that’s not because they stop eating―quite the opposite. Even though these rats are eating food, their bodies can’t process it in the normal way. On top of that, their little bodies lose more heat than normal, which makes them weak. This means that they need more food to stay at a healthy temperature.

And that’s what lack of sleep does for you.

第1题:
【文章大意】睡眠不足是危险的
你知道如果你错过太多睡眠你会死吗？这是真的！如果你长时间保持清醒，你的大脑和身体就会崩溃。
保持清醒的非官方世界纪录是 11 天，由 Randy Gardner 完成。兰迪请他的两个朋友阻止他入睡。他还得到了电视和广播记者、睡眠研究人员和医生的帮助。
发生了什么？首先，长时间保持清醒让兰迪脾气暴躁。然后他的大脑开始失去知觉。第 4 天，他把路牌认成了一个人。第 6 天，他开始说话很慢。第 9 天，他无法说出整个句子。第 10 天，兰迪以为他在隔壁房间看到了一片森林。事实上，他有点发疯了。最终，在他打破世界纪录后，兰迪被告知去睡觉。让人们长时间保持清醒的实验总是在病人崩溃之前停止。
然而，老鼠并没有得到很好的照顾。如果不让他们睡觉，他们会在三周内死亡。这比让他们睡觉但不给他们食物要快。他们变得非常瘦。但这并不是因为他们停止进食——恰恰相反。即使这些老鼠正在吃食物，它们的身体也无法以正常方式处理食物。最重要的是，他们的小身体比正常情况失去更多的热量，这使他们变得虚弱。这意味着他们需要更多的食物来保持健康的温度。到最后，这些老鼠的健康正在衰退。
这就是睡眠不足对你的影响。
【选项释义】
A.事实上，他有点疯了。
B.正常情况下，老鼠不会感冒。
C.到最后，这些老鼠的健康正在衰退。
D.如果不让他们睡觉，他们会在三周内死亡。
E.兰迪请他的两个朋友阻止他入睡。
F.首先，长时间保持清醒让兰迪脾气暴躁。
【答案】E
【原文考查】上下文关联题
【解题思路】根据空格处前一句“保持清醒的非官方世界纪录是 11 天，由 Randy Gardner 完成。”以及空格处后一句“他还得到了电视和广播记者、睡眠研究员和医生的帮助”可知，后面两句都是表达兰迪•加德纳能够保持清醒所得到的一些帮助。因此E选项“兰迪让他的两个朋友帮忙阻止他睡着”符合语境。故本题选E。
第2题:
【答案】F
【原文考查】推理判断题
【解题思路】根据空格处后面的内容可知，后面是记录兰迪保持清醒的天数以及出现的一些状况。所以空格处应该记录的是兰迪保持清醒最开始出现的一些状况。因此选项F“首先，长时间保持清醒使兰迪脾气暴躁”符合题意。First of all和后面的then构成了先后的逻辑关系。故本题选F。
第3题:
【答案】A
【原文考查】上下文关联题
【解题思路】根据空格处前一句“第10天，兰迪以为自己在隔壁房间看到了一片森林”以及后一句“最终，在他打破世界纪录后，兰迪被要求去睡觉”可知，此时的兰迪由于长时间的保持清醒已经有点神志不清了，所以A选项“事实上，他有点疯了”符合原文语境。故本题选A。
第4题:
【答案】D
【原文考查】上下文关联题
【解题思路】本段涉及到的对象是老鼠，根据空格处后一句中的关键信息“sooner（更快地，更早地）”可知，空格处的信息应该与时间相关。因此D选项“如果不让他们睡觉，他们会在三周内死亡”符合题意。这与后面的允许它们睡觉但不给食物的情况形成了对比，所以正确。故本题选D。
第5题:
【答案】C
【原文考查】上下文关联题
【解题思路】根据空格处前面的内容可知，前面都是在描写实验中的老鼠，讲述它们的身体是如何慢慢的发生变化。所以C选项“最后，这些老鼠的健康状况正在恶化”符合语境。故本题选C。
