15．When you were a child，did you ever sleepwalk？
According to doctors，up to 17percent of children have a sleepwalking experience．It affects about 4percent of adult population．
Here is what can happen when a person is sleepwalking：He or she gets out of bed and climbs out a window．Or，they get out of bed，walk down the hallway，around in a room or two，and maybe，open the front door and step outside．
The behaviors of sleepwalkers are similar：they often have open eyes，although they have a glassy （呆滞的） look．They might talk，although not clearly．Waking them will result in serious confusion，so experts say it is best not to．
"Monitor it，but let it run its course，unless they are headed out the front door，"said Jodi Mindell，a US psychologist．It can help to guide them back to bed，where they will probably fall back asleep and have no memory of what happened after they wake up．
What you have with a sleepwalker is a"sleeping brain and an awake body，"said Donna Arand，director of the sleep disorder center at Kettering Medical Center，US．"Sleepwalkers tend to do things typical of daytime activities．"
Why does it happen？
Everyone has a sleep cycle，which lasts between 90and 120minutes and repeats itself through the night．
The cycle is divided into REM （rapid eye movement） sleep and non-REM sleep．The non-REM part occurs first and is itself divided into three stages．Sleepwalking nearly always happens in the third stage of non-REM sleep，generally the deepest sleep of the night．The stages are marked by different brain wave activity，and in stage three，the brain waves become really slow．Then suddenly，in some people，bam!Out of bed and sleepwalking．
How come？We don't know．
"We have no idea of what's going on in the brain，"said Mindell，who has been studying sleep for more than 20years．Experts suggest that reducing stress and getting enough sleep could prevent adults from sleepwalking．

46．Which of the following is NOT usual behavior for a sleepwalker？C
A．Getting out of bed and walking around．
B．Talking unclearly．
C．Doing daily activities with eyes closed．

A．We should talk to him or her if he starts talking．
B．We should follow the sleepwalker wherever he or she goes．
C．We should limit his or her activities to the house．
D．We should wake him or her up in the act．
48．What can we learn from the passage？B
A．Not everyone has non-REM sleep．
B．Sleepwalking mostly happens during the deepest sleep．
C．Different brain wave activity marks stages of our sleep cycle．
D．Sleepwalking is caused by slow brain waves．
