问题 　　Are you a real grump (脾气坏的人) in the mornings? Do you wake up every day feeling tired, angry and upset, and all too ready to flit the snooze (瞌睡) button? If so, then a new alarm clock could be just for you.　　The clock, called SleepSmart, measures your sleep cycle, and waits for you to be in your lightest phase of sleep before waking you up, Its makers say that should ensure you wake up feeling refreshed (恢复精力) every morning.　　As you sleep you pass through a sequence of sleep states—light sleep, deep sleep and REM sleep (快速眼动睡眼)—that repeats approximately every 90 minutes. The points in that cycle at which you wake can affect how you feel later, and may even have a greater impact than how long or little you have slept. Being wakened during a light phase means you are more likely to wake up cheerful and full of life and interest.　　SleepSmart records the distinct pattern of brain waves produced during each phase of sleep, via a headband equipped with electrodes (电极) and a microprocessor. This measures electric activity of the wearer’s brain, and communicates wirelessly with a clock unit near the bed. You program the clock with the latest time at which you want to be wakened, and it then at the proper time wakes you during the last light sleep phase before that.　　The concept was invented by a group of students at Brown University in Rhode Island after a friend complained of waking up tired and performing poorly on a test. “As sleep-deprived (剥夺) people ourselves, we started thinking of what to do about it,” says Eric Shashoua, a recent college graduate and now chief executive officer of Axon Sleep Research Laboratories, a company created by the students to develop their idea. They have almost finished a prototype and plan to market the product by next year.
选项
答案
解析 你在早上会是一个坏脾气的人吗？你每天醒来时都会疲惫、生气、太容易打瞌睡吗？如果这样，你应该为自己设置一个新的闹钟
　　这个闹钟就叫做SleepSmart，它能测量你的睡眠周期，等到你睡得最浅的时候再把你叫醒。它的发明者说这能保证你每天早上醒来的时候都能恢复精力。
　　当你在睡觉时，会经过一系列睡眠状态——浅睡，熟睡和快速眼动睡眠—每90分钟循环一次。你在这个周期中醒来的时间点会影响之后的感受，并可能比睡觉时间的长短对你的影响更大。在浅睡阶段醒来意味着你更容易感到精神振奋，充满活力。
　　SleepSmart通过一个配备电机和微处理器的头带记录每个睡眠阶段产生的不用模式的脑电波。头带能测量穿戴者脑部的电流活动并无线连接床边的闹钟。你可以把闹钟设置到你想要被叫醒的最晚时间，之后它就会在离这个时间最近的一个浅睡阶段让你醒来。
　　在一位朋友抱怨睡醒之后感到疲惫并在考试中状态不佳后，罗德岛布朗大学的一群学生想出了这个主意。“我们本身也是睡眠不足的人，于是就开始思考怎么解决这个问题” Eric Shashoua说道。他刚从学校毕业不久，现在是Axon睡眠研究实验室的CEO，这家由学生创立的公司让他们尽情发挥自己的想法。他们现在差不多开发出了原型并计划明年将产品打入市场。
