　　Going to sleep may seem pretty boring compared with all the fun things there are to do while you're awake．But there's a lot going on in your mind and body while you're tucked under those covers．

　　Sleep, in fact, is as important to your survival as eating and drinking．Sleep improves your mood, makes you a better athlete, and helps you remember and understand what you learned during the day．During sleep your temperature drops．Your heart rate slows．Down goes the pressure of the blood moving through your veins．A chemical that controls growth(called a hormone)surges into your bloodstream．Scientists think sleep restores energy and improves your immune(免疫)system．We know what happens while we're asleep because scientists study volunteers who sleep in laboratories．The sleepers are hooked up to machines that measure brain waves, eye movements and muscle activities．

　　Sleep is like a school day：it's divided into different periods, or stages．When you're awake, your brain waves fire rapidly．As you begin to relax and drift into the first stage of sleep, your brain produces slower-moving waves and you lose awareness of your surroundings．As you slide to deeper sleep, your body repairs itself from the normal wear and tear of daily life．Then, as you begin to drift back up to a lighter sleep, your mind becomes more alert(机警), and your dreams begin．You're in REM sleep．

　　REM was names far the“rapid eye movement' that happens while you're dreaming．During REM sleep, your eyes move back and forth behind your timed lids, as though you were washing a movie．During other stages, you might move at that in bed, but during REM sleep you're still．That's probably because if you could move, your body would act out your dreams．As you get closer to morning, you spend more time in REM than in deep sleep, so you dream more．Researchers know that during REM sleep the part of the brain that handles learning and thinking is very active．

　　Getting too little sleep can affect your personality．Experts recommend that children get at least nine hours d sleep a night．So sleep fight．

     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, 20 employees, $14 million 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 3 pm.
     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 level
1. Who will support Zeo? 
A. People full of imagination.
B. People suffering sleeping problems.
C. People having access to the Internet.
D. People having bad lifestyles.
2. Why did the three graduate students imagine a smart alarm clock?
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.
3. To design the Zeo device, the three graduate students ____.
A. spent much time and money
B. were widely supported by scientists
C. worked by themselves all the time
D. attracted many investors .
4. What can we know from the passage?
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

                                                     The Meanings of Dreams
     Sleep and dreams have interested people for centuries. Scientists are learning more about sleep, but
they still know very little about why we dream. 
       1   First, we have most of our dreams during REM (rapid eye movement) sleep. At this time, the
brain is very active. Second, everyone dreams - even if we cannot remember doing so when we awaken.
    2   While we are asleep, it works more slowly and sometimes puts our thoughts and memories together
in strange ways. 
        3   Some believe that our dreams are associated with thoughts and feelings that we experience
while we are awake. Many dream researchers think that a dream about death, for example, is really
about an important life change.    4   Dreams about a car or travel often represent feelings about your
own life. Dreams about teeth - especially broken or loose ones may indicate stress and fear. Dreams in
which you are flying often represent freedom or escape.
    Researchers think people in our dreams can tell us something about ourselves. If the person in the
dream was yelling (叫喊), for example, maybe you are angry.    5  
    There is still a lot about dreaming that we do not understand. By learning more about our dreams, we
may learn more about ourselves.

A. Dreams may be more important than sleep.
B. Scientists do not know for certain why we dream.
C. If he or she was terrified, then maybe you are afraid of something.
D. Modern research can tell us some important things about dreams.
E. There are three things you should pay attention to to have a sweet dream.
F. Finally, a part of our brain helps us to understand daily experiences we have.
G. Dreams about telephones are thought to be about giving or receiving an important message.

     Are you tired?Do you often catch colds and flu?If so, you might consider changing your sleep habits.
Good health demands good sleep.Studies have shown that most people need eight hours of sleep each
night.Americans, however, on average, get only seven hours.Onethird of us get just six hours, and good
health is not simply a matter of how much sleep you get, but also the type of sleep you get.
     Nonrapid eye movement (NREM) sleep allows your body to grow and repair itself.During NREM
sleep, your muscles relax.Your heart rate and breathing rate decrease.Your eyes roll slowly back and
forths then they stop moving.Most of the sleeping you do is NREM sleep.
     Rapid eye movement (REM) sleep restores your brain.During REM sleep, you dream.You may not
remember every dream, but every time you sleep, you dream.Your eyes move back and forth quickly.
Your breathing rate and heartbeat increase.Your muscles become paralysed (麻痹的). About 25 percent of your sleep is REM sleep.You need enough of both kinds of sleep to be healthy.
     Is it a real concern if you don't get enough good sleep?It certainly is.Poor sleep puts you and others at
risk.More than 100,000 car accidents are caused each year by drivers who nod off (打盹). Almost $100 billion is lost yearly in the business and environmental field.People deprived_of sleep have been factors in
the Challenger space tragedy, the Exxon Valdez oil spill (溢出), and the Chernobyl nuclear reactor
accident.So do yourself and everyone around you a favour.Don't cheat yourself out of good sleep!
