While it’s easy enough to brush off a few sleepless nights with a pot of coffee and the occasional desk nap, you may be doing more harm than you realise. According to a new study from Surrey University, having less than six hours of sleep per night can actually shut down genes that play a key role in the body’s【C1】______of self-repair.
We rely on our genes to constantly produce the proteins needed to【C2】______the wear on our bodies’ tissue that we suffer throughout the day. But when scientists divided 26 volunteers into two groups— one of which slept for less than 6 hours per night for an entire week and the other for 10 hours per night—some of the sleep-deprived group’s genes actually stopped working.
The functions of 711 genes in total were altered in some way,【C3】______ones involved in metabolism(新陈代谢), inflammation(炎症), immunity and stress. There is some good news though; a week of normal sleep was enough to【C4】______the malfunctioning genes back to peak condition, but should the【C5】______sleep patterns continue, health problems that aren’t quite so easily reversible, like obesity(肥胖)and heart disease, have a【C6】______chance of cropping up. And this study only scratches the【C7】______according to Professor Colin Smith, one of the scientists【C8】______in the study: This is only a week of sleep【C9】______and it is only five and a half or six hours a night, Many people have that amount of sleep for weeks, months and maybe even years so we have no idea how much【C10】_______ it might be.
A)experiment I)slight
B)high J)specifically
C)involved K)substitute
D)namely L)surface
E)process M)unhealthy
F)restore N)unstable
G)restriction O)worse
H)reverse
【C9】
选项
答案
G
解析
空格处应填入能被sleep修饰的名词。根据上文提到的科学家让其中一组志愿者睡眠不足6小时可知,此处应指“睡眠限制”,故空格处填入restriction与文意相符。
