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【S1】______of self-repair.
We rely on our genes to constantly produce the proteins needed to【S2】______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,【S3】______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【S4】______the malfunctioning genes back to peak condition, but should the【S5】______sleep patterns continue, health problems that aren’t quite so easily reversible, like obesity(肥胖) and heart disease, have a【S6】______chance of cropping up. And this study only scratches the【S7】______, according to Professor Colin Smith, one of the scientists【S8】_______ in the study: This is only a week of sleep【S9】______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【S10】______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
【S7】
选项
答案
L
解析
空格处缺少句子宾语,故应填入名词。根据下文Colin Smith教授讲到的“该项研究仅为期一星期,并且每晚只有5个半或6个小时的睡眠时间”,可知该项目未做深入研究,故空格处填入surface与文意相符,意为“该研究只是触及表面”。
