2.We spend a quarter of our lives asleep.Sleep is necessary for the body to rest,yet our brains continue to process information.Studies have shown that students are more successful when they sleep after studying-instead of pulling all-nighters-because the brain reviews information learned.Similarly,dreaming is an opportunity to work out emotional problems and form thoughts and memories.About 25 percent of the time spent sleeping is spent in rapid eye movement,or REM,sleep.This type of sleep is known for when dreams occur,but it also helps energize the brain and body.
Researchers have found two important factors regarding humans and sleep:basicsleep need and sleep debt.Basic sleep need is the amount of sleep we need to have regularly to perform at our best.Sleep debt is the loss of sleep.A few studies say that most adults function best with a basic sleep need of seven to eight hours a night.The problem is that sleep debt also factors in,just because that you meet your basic sleep needs a few nights of the week doesn't mean it cancels out the eff6ects of one night's sleep debt.
Of course,everyone is different and some people require more or less sleep than the standard basic sleep need.But the real problem lies in what lack of sleep does over the long period to people who either does not meet his or her body's needs or for one reason or another doesn't get enough regular sleep.It is more possible for these people to have motor vehicle accidents,weight gain and risk for heart disease or diabetes (糖尿病) and may be at increased risk for psychological conditions such as depression or drug abuse.Sleeping too long also can be associated with depression and poor health.
33.Most peoplespent aroundCof the sleeping time in REM sleep?
A.One third of the time                 
B.More than half of the time  
C.One fourth of the time                
D.More than 5 hours every day
34.Which of the following is NOT the result for lack of sleep according to the passage?D
A.Car accidents.
B.Putting on weight.
C.Heart problems.
D.Review learning things.
35.The best title for the passage isA.
A.Why We Need Sleep                 
B.REMSleep and Basic Sleep
C.Sleep Causes Problems                 
D.How Much Sleep We Need
36.Which statement is TRUE according to the passage?B
A.Students will forget what they have learned if they go to sleep immediately after study.
B.People may have an idea on how to solve an emotional problem if they have a dream.
C.It's all right to have a night of sleep debt if you fulfill several days of basic sleep need.
D.Sleeping as long as you can is considered to be good for your health and performance.

1.On a hot summer's day Jonathan and his classmates were anxiously sitting in their classroom,waiting for the final bell of the day to sound.Jonathan prayed that the bell would ring soon,because he wanted to quickly run home before the three huge,fat,smelly bullies (地痞) could see him.Every day the three bullies would wait there for an innocent school kid to tease and bully.
The moment the bell sounded,Jonathan rushed out with his bag.He sped off across the school field and out onto the walkway.However,all of his effort was useless because leaning on a fence were the three bullies.

Beside them was a small dirty stream.
"Let's throw him in there",said one of the bullies.
Then they threw Jonathan into the stream and walked off down the walkway.Jonathan shakily picked himself up out of the creek and continued his walk home with his head down and tears in his eyes.He dared not cry because he knew boys didn't cry.
