题目内容
10．Few of us make money by losing sleep．But three graduate students at Brown University in Providence built a company around sleep deprivation （睡眠不足）．Jason Donahue，Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schools．They began thinking about ways to sleep better．They discovered they weren't alone in burning the midnight oil．Around 20% of Americans get less than six hours of rest a night．
The friends imagined a smart alarm clock that could track how much time people spend in the most restorative （有回复作用的） stages of the sleep cycle：REM （rapid eye movement） and deep sleep．What would it cost to design such a thing？Five years of research，20employees，﹩14million and a whole lot of doubting from investors and scientists．
Their company，Zeo，based in Newton，Mass，launched its product in June，2009．The Zeo device uses a headband with tiny sensors （传感器） that scan your brain for signs of four sleep states-REM，light，deep and waking sleep．The smart alarm clock displays a graph of your sleep pattern and wakes you as you're not in REM sleep （which is when you're least groggy）．In the morning you can upload the data to the company's Web site，and so track your sleep over time．Most of the feedback comes in the form of Zeo's ZQ score showing how well you've slept．
"Zeo allows people to unlock this black box of sleep，"says Dave Dickinson，a health-care CEO．
Whether any of this actually improves sleep is up to the consumer，who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3pm．
For now the company is selling Zeo online only．Dickinson also plans to spread it to countries such as Australia，where sleep deprivation approaches US levels．
56．Who will support Zeo？B
A．People full of imagination．
B．People suffering sleeping problems．
C．People having access to the Internet．
D．People having bad lifestyles．
57．Why did the three graduate students imagine a smart alarm clock？C
A．To wake them up on time in the morning．
B．To earn enough money for their study．
C．To improve the quality of people's sleep．
D．To enjoy their life while working at night．
58．To design the Zeo device，the three graduate studentsA．
A．spent much time and money
B．were widely supported by scientists
C．worked by themselves all the time
D．attracted many investors
59．What can we know from the passage？B
A．Zeo has a direct effect on users'lifestyles．
B．It needs more personal efforts to make Zeo function better．
C．A large quantity of Zeo devices have been sold in Australia．
D．Consumers can go to the Zeo company to purchase Zeo in person．
分析 本文是一篇科教类阅读，主要介绍了一种可以帮助人们改善睡眠的Zeo头环．
解答 56-59．BCAB
56题答案：B考查细节推理，根据文章第四段的The Zeo device uses a headband with tiny sensors （传感器） that scan your brain for signs of four sleep states-REM，light，deep and waking sleep．（Zeo使用一个附带微型传感器的头环来扫描你的大脑四种睡眠状态的信号--REM、轻度、深度、睡眠清醒）及倒数第二段的Zeo allows people to unlock this black box of sleep．（Zeo使人们解开睡眠的黑匣子）可知Zeo对于遭受睡眠困扰的人是有帮助的，故本题答案为B选项．
57题答案：C考查细节推理，根据文章第二段的They began thinking about ways to sleep better．（他们开始思考改善睡眠的方法）可知本题答案为C选项．
58题答案：A考查细节推理，根据文章第三段的Five years of research，20employees，﹩14million and a whole lot of doubting from investors and scientists．（20位员工5年的研究、140万美元的费用还有来自投资者与科学家的种种质疑）可知本题答案为A选项．
59题答案：B考查细节推理，根据文章最后一段的Whether any of this（Zeo） actually improves sleep is up to the consumer，who will also need to make lifestyle changes…（是否Zeo真的能改善睡眠取决于消费者--他们也需要对生活方式做出改变…）可知本题答案为B选项．
