Passage FourAfter a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!46. A good title for this passage is ______.A. SleepB. Good HealthC. DreamsD. Work and Rest

One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.
For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.
Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.

Text 4 When you go to bed,is it because you're tured or because you need to get up at a certain time and want to make sure you get enough sleep?Everyone has a chronotype,which is the sleep cycle that their body would naturally prefer,if left to its own devices.But society forces its own chronotype on people,too.Maybe your prefer to sleep from 2 a.m.t0 10 a.m.But if you have a typical 9-to-5 workday,to get eight hours,you'd probably need to sleep from something like 11 p.m.t0 7 a,m.Individuals'sleep is surely shaped by their jobs,their families,and their habits.But a new study shows that society can shape sleep broadly,on a population level,as well.In the paper,published in Science Advances,Olivia Walch,Amy Cochran,and Daniel Forger of the University of Michigan look at data gathered from a smartphone app to see how sleep cycles vary in different countries and among different demographics.What country people lived in didn't have any noticeable effect on when they woke up,but it was linked to what time they went to bed.And what time they went to bed was linked to how much sleep they got.So in the countries that got less sleep on average,like Japan and Brazil,it was because they were going to bed later,not because they were waking up earlier than people in countries that got more sleep on average,like the Netherlands and Belgium,where people have earlier bedtimes.But it's notable in pointing out bedtime as a problem area.A lot of the research and discussion about the tension between sleep and society has focused on the morning-how the 9-to-5 workday isn't suitable for everyone's internal clocks,how starting the school day later can help teens,who have notoriously late chronotypes,how exposing yourself to light in the moming can help keep your intemal clock wound in a way that promotes good sleep.Bedtime,meanwhile,seems like it should be more of a choice.You wake up to go somewhere,or to start fulfilling responsibilities,and you go to bed when you decide to,based on a complex calculus of how tired you are,how much sleep you want to get,and whether the chapter you were just reading in your book ended on a cliffhanger.But when people are deciding to go to bed differs significantly across societies,it seems there's something cultural at play here,too.
From the discussion about moming,we can infer that____A.9-to-5 workday is not welcomed by most people
B.most teenagers wake up too late to school
C.what is the best time to get up is still uncertain
D.school children are notorious for going to bed too late

问答题Practice 1 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.
