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】________.
【C1】
选项
A、by chance
B、on average
C、at length
D、for good
答案
B
解析
下一句的the average amount说明本空格所提到的the amount of sleep为平均睡眠时间,故B项on average “平均”为答案,表示英国人睡眠时间整体的情况。A项by chance“偶然地”,指偶发性,此处是指英国人睡眠状况的趋势,并非偶发。C项at length “最终”,表结果,逻辑不对。D项for good“永久地”,从本句末over the years可知是这些年的情况,并不可知是否永久。
