四六级考试12月大学英语四级词汇活记活用(21)完型填空练习:Do you wake up every day feeling too tired, or even upset? If so, then a new alarm clock could be just for you.The clock, called SleepSmart, measures your sleep cycle, and waits _1_ you to be in your lightest phase of sleep _2_ rousing you. Its makers say that should _3_ you wake up feeling refreshed every morning.As you sleep you pass _4_ a sequence of sleep stateslight sleep, deep sleep and REM (rapid eye movement) sleepthat _5_ approximately every 90 minutes. The point in that cycle at which you wake can _6_ how you feel later, and may _7_ have a greater impact than how much or little you have slept. Being roused during a light phase _8_ you are more likely to wake up energetic.SleepSmart _9_ the distinct pattern of brain waves _10_ during each phase of sleep, via a headband equipped _11_ electrodes (电极) and a microprocessor. This measures the electrical activity of the wearers brain, in much the _12_ way as some machines used for medical and research _13_, and communicates wirelessly with a clock unit near the bed. You _14_ the clock with the latest time at _15_ you want to be wakened, and it _16_ duly (适时地) wakes you during the last light sleep phase before that.The _17_ was invented by a group of students at Brown University in Rhode Island _18_ a friend complained of waking up tired and performing poorly on a test. “_19_ sleep-deprived people ourselves, we started thinking of _20_ 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.1.
