河北省辛集市2017高考英语信息匹配及任务型阅读训练（8）及答案 【2017高考复习】任务型读写 A study published Monday found that people who sleep less tend to be fat，and experts said it’s time to find out if more sleep will fight fatness. “We’ve put so much emphasis on diet and exercise that we’ve failed to recognize the value of good sleep，”said Fred Turek，a physician at Northwestern University. Monday’s study from Eastern Virgnia Medical School in Norfolk covered 1,000 people and found that total sleep time decreased as body mass index－a measure of weight based on height increased. “Men slept an average of 27 minutes less than women and overweight and fat patients slept less than patients with normal weights，”it said.In general the fatter subjects slept about 1.8 hours a week less than those with normal weights. “Americans experience insufficient sleep and fat bodies.Clinicians are aware of the burden of fatness on patients，”the study said. “Our findings suggest that major extensions of sleep time may not be necessary，as an extra 20 minutes of sleep per night seems to be associated with a lower body mass index，”it added. “We caution that this study does not set up a causeandeffect relationship between restricted sleep and fatness，but investigations indicating success in weight loss via extensions of sleep would help greatly to set up such a relationship.” |
