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 [br] 【C5】
选项
答案
M
解析
此处应填动词。本句意思是“缺少睡眠使事情变得 ”,联系下文,如果睡眠少于平均时间,就会背上“睡眠债”,身体机能衰退,造成恶性循环,选项中cornlplicates“使复杂化,使恶化”,符合句意,因此选complicates。
