Going to sleep at a certain time is associated with a lower risk of developing heart disease, according to researchers. In a study published in the European Heart Journal, a team found that going to sleep between 10:00 pm and 11:00 pm was beneficial compared to earlier or later bedtimes. The research included 88,026 participants in the UK.
An analysis found that sleep onset time of 10:00 pm to 10:59 pm was associated with the lowest incidence of heart disease. There was a 25% higher risk of heart disease with sleep onset at midnight or later, a 12% greater risk for 11:00 pm to 11:59 pm and a 24% higher risk for falling asleep before 10:00 pm compared to sleep onset from 10:00 pm to 10:59 pm.
“The body has a 24⁃hour internal clock that helps adjust physical and mental functioning.” Study author David of the University of Exeter said in a statement. “While we cannot conclude from our study, the results suggest that early or late bedtimes may be more likely to destroy the body clock.” “While the findings do not show conclusion, sleep timing has appeared as a potential heart disease risk factor—independent of other risk factors. If our findings are proved in other studies, sleep timing and basic sleep health could be a low⁃cost public health target for lowering risk of heart disease.” David added.
一系列研究发现睡眠时间对心脏病有影响。
1.Which is the best time for sleep?
A. 8:40 pm. B. 9:50 pm.
C. 10:45 pm. D. 11:10 pm.
答案与解析 C 细节理解题。由第一段中“that going to sleep between 10:00 pm and 11:00 pm was beneficial compared to earlier or later bedtimes”可知,在晚上10点到11点之间是最好的睡觉时间。故选C。
2.How is paragraph 2 organized?
A. By giving some data.
B. By raising a question.
C. By giving an example.
D. By following the time order.
答案与解析 A 写作手法题。第二段中提到与晚上10点至10点59分入睡相比,午夜或更晚入睡的人患心脏病的风险增加25%,晚上11点至11点59分入睡的人患心脏病的风险增加12%,晚上10点之前入睡的人患心脏病的风险增加24%。由此可推断,第二段是通过提供数据阐述的。故选A。
3.What can be inferred from Davids words?
A. Sleep too early will sur
