The average British people get six-and-a-half hours’ sleep a night, according to the Sleep Council. It has been known for some time that the amount of sleep people get has,【C1】______declined over the years.
But【C2】______the average amount of sleep we are getting has fallen, rates of obesity and diabetes have soared. Could the two be connected?
We wanted to see what the【C3】______would be of increasing average sleep by just one hour. So we asked seven volunteers, who【C4】______sleep anywhere between six and nine hours, to be【C5】______at the University of Surrey’s Sleep Research Centre.
The volunteers were randomly【C6】______to two groups. One group was asked to sleep for six-and-a-half hours a night, the other got seven-and-a-half hours. After a week the researchers took blood tests and the volunteers were asked to switch sleep【C7】______. The group that had been sleeping six-and-a-half hours got an【C8】______hour, the other group slept an hour less.
Computer tests designed to measure brain wave activity【C9】______that most of them struggled with mental agility tasks when they had less sleep, but the most interesting results came from the blood tests that were【C10】______.
Dr Simon Archer and his team at Surrey University were【C11】______interested in looking at the genes that were switched on or off in our volunteers【C12】______changes in the amount that we had made them sleep.
"We found that【C13】______there were around 500 genes that were affected," Archer【C14】______. "Some which were going up, and some which were going down."
What they discovered is that when the volunteers【C15】______back from seven-and-a-half to six-and-a-half hours’ sleep a night, genes that are【C16】______with processes like immune response and response to stress became more【C17】______The team also saw increase in the activity of genes related to diabetes and risk of cancer. The【C18】______happened when the volunteers added an hour of sleep.
So the clear【C19】______from this experiment was that if you are getting less than seven hours’ sleep a night and can alter your sleep habits, even one hour more, it could make you【C20】______.
【C12】
选项
A、at
B、to
C、by
D、for
答案
C
解析
从空格前的句意“……观察在志愿者体内的基因活跃情况(genes that…in our volunteers)”和空格后的句意“我们设置的睡眠量的变化”可知,空格前的动作为目的,而空格后的则为方式,故应选用C项by“通过”。
