BEIJING, Jan. 11(Xinhuanet)-- Sleeping a little bit longer a day might help fight against obesity（肥胖）, a recent study shows. The rearch-- published in the Archives of Internal Medicine along with an editorial by Turek and Northwestern colleague Joph Bass commenting on it and related rearch-- after comparing people of normal weight- a body mass index of less than 25- with tho who were overweight or obe , found that sleeping for an extra 20 minutes each night could offer a pain-free way to lo weight.Insufficient sleep is linked with changes in hormone levels that may stimulate（刺激）appetite. A ries of studies in recent months have shown that the less people sleep, the heavier they tend to be.American rearcher Robert Vorona from Eastern Virginia Medical School in Norfolk and colleagues have now examined the relationship between people's lf-reported sleep time per 24 hours and their body mass index(BMI). They found that total sleep time and BMI were inverly correlated was total sleep time decread, BMI incread, except in the verely obe group." Americans experience insufficient sleep and corpulent bodies. Clinicians are aware of the burden of obesity 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 ems to be associated with a lower body mass index," it added. "We warn that this study does not establish a cau-and-effect relationship between restricted sleep and obesity (but) investigations demonstrating success in weight loss via extensions of sleep would help greatly to establish such a relationship."In November 2004, rearchers from Columbia University in New York City, New York demonstrated a clear link between the risk of being obe and hours of nightly sleep, finding that people aged 32 to 59 who slept four hours or less per night were 73% more likely to be obe than people who slept between ven and nine hours per night.小题1:The rearch, which was published in the Archives of Internal Medicine, found that____________.sleeping for a shorter time a day might help fight agianst obesityan extra 20 minutes’ sleep each night could offer a way to lo weight wothout paintotal sleep time and body mass index were inverly relatedpeople aged 32 to 59 who slept four hours or less per night were 73% more likely to be obe than people who slept between ven and nine hours per night小题2:How many rearch results are prented in the text?A．Two B．ThreeC．FourD．Five小题3: What does the underlined word “obs” probably mean?A．thinB．fatC．energeticD．painful小题4:According to the text , the author intends to tell us that _____________________.A．Sleeping a little bit longer a day might help fight against obesityB．insufficient sleep is linked with changes in hormone livesC．there exists a clear link between the risk of being obes and hours of nightly sleepD．the less people sleep , the heavier they tend to be 题型：未知难度：其他题型
