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)______. To fall asleep, you need adequate time to unwind, (6)______ you feel fatigued, not so easy to(7)______ "turn off."
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. Now a vicious(13)______ has been created: You experience the feeling of being more and more tired,(14)______ your body is increasingly stimulated. Power sleeping for more hours on weekends is only a(15)______ solution. "There is no(16)______ for getting a good night’s sleep on a(17)______ basis," says Hunt.
Most of us,(18)______, don’t get the sleep we need. According to the 2002 National Sleep Foundation, Americans sleep a(n)(19)______ of 6.9 hours per night during the week, and 58 percent of adults experience (20)______ of insomnia a few nights a week or more. [br] (16)
选项
A、replacement
B、exchange
C、shift
D、substitute
答案
D
解析
词汇辨析题。上文提到一个解决方法,此句的no和a good night’ssleep表明此处要表达“替代”之意。选项中能与:for搭配的是substitute.故D为答案。replacement也有“替代”的意思,但一般和of搭配;exchange“交换,兑换,交流”和shift“移动,轮班,变化”与语义不符。
