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
【S6】
选项
答案
B
解析
空格前后分别是不定冠词a和名词chance,故应填入形容词。本句主语为health problems,上半句为假设句,意为“若不健康的睡眠模式继续下去的话”,空格所在的半句为结果,即“健康问题突发的几率很高”,故空格处应填入high。slight“微小的”,与句意相反,故排除;unstable“不稳定的,紊乱的”,不符合文意,故排除。
