Why is it so difficult to fall asleep when you are overtired? There is no one answer that【C1】______to every individual. But many people fail to note the【C2】______between fatigue— physical tiredness—and sleepiness, the inability to stay awake. It’s possible to feel "tired" physically and still be unable to fall asleep, because while your body may be exhausted, you don’ t feel sleepy. To fall asleep, you need adequate time to unwind, even if you feel fatigued. It’ s not so easy to【C3】______"turn off."
According to Carl E. Hunt, director of the National Centre on Sleep Disorders Research in Bethesda, Maryland, most people do not allow themselves【C4】______deceleration.
Lack of sleep【C5】______matters even more. Experts say adults need at least 7 to 8 hours of sleep a night to【C6】______properly. When you get less sleep than that on【C7】______nights, you begin to accrue "sleep debt." As sleep debt increases(and functionality decreases), your body experiences a stress response and begins to release adrenaline. Now a vicious cycle has been created: You experience the feeling of being more and more tired, but your body is increasingly stimulated. "Power sleeping" for more hours on weekends is only a【C8】______solution. "There is no【C9】______for getting a good night’ s sleep on a regular basis," says Hunt.
Most of us, however, don’ t get the sleep we need. According to the 2002 National Sleep Foundation, Americans sleep an average of 6.9 hours per night during the week, and 58 percent of adults experience【C10】______of insomnia a few nights a week or more.
A)adapts B)rarely C)symptoms D)sufficient
E)function F)contemporary G)temporary H)replacement
I)consecutive J)distinctions K)similarities L)substitute
M)complicates N)simply O)applies
【C3】
选项
答案
N
解析
从语法可知,此处缺副词。再分析句意“要入睡,你得有充足的时间来放松,即便你已感到疲倦。要想——一‘突然入睡’并没有那么容易。”选项中simply“简单地”符合句意,排除rarely“很少地,难得”。
