Why is it so difficult to fall asleep when you are overtired? There is no one answer that(1)______ to every individual. But many people fail to note the(2)______ between fatigue — physical tiredness — and sleepiness, the inability to(3)______ awake. It is possible to feel tired(4)______ and still be unable to fall asleep, because while your body may be exhausted, you don’t feel(5)______.

According to Carl E. Hunt, director of the National Center on Sleep Disorders Research in Bethesda, Maryland, most people do not allow themselves(8)_____ deceleration.
Lack of sleep(9)______ matters even more. Experts say adults need at least 7 to 8 hours of sleep a night to (10)______ properly. When you get less sleep than(11)______ on consecutive nights, you begin to accrue "sleep debt".(12)______ sleep debt increases and functionality decreases, your body experiences a stress response and begins to release adrenaline.

选项
A、deficient
B、decent
C、sufficient
D、extreme
答案
C
解析
语义线索题。前面文中提到“要入睡,你得有充足的时间来放松”,本句引用卡尔.E.亨特的话说明。大多数人都没有给自己充分的舒缓时间,以此进一步说明上文提到的观点,故C项sufficient“充分的,足够的”正确。deficient“缺乏的,不足的,不完善的”;decent“正派的,端庄的,得体的”;extreme“极端的,极度的”。
