In what may be bad news for bars and pubs,a European research group has found that people drinking alcohol outside of meals have a significantly higher risk of cancer in the mouth and neck than do those taking their libations with food.Luigino Dal Maso and his colleagues studied the drinking pattems of 1 ,500 patients from four cancer studies and another 3,500 adults who had never had cancer.
After the researchers accounted for the amount of alcohol consumed,they found that individuals who downed a significant share of their alcohol outside of meals faced at least a 50 to 80 percent risk of cancer in the oral cavity（腔）,pharynx（咽）,and esophagus（食管）,when compared with people who drank only at meals.Consuming alcohol without food also increased by at least 20 percent the likelihood of laryngeal（喉）cancer."Roughly 95 percent of cancers at these four sites traced to smoking or drinking by the study volunteers,"Dal Maso says.The discouraging news,his team reports, is that drinking with meals didn't eliminate cancer risk at any of the sites.
For their new analysis,the European scientists divided people in the study into four groups, based on how many drinks they reported having in an average week.The lowest-intake group includ-ed people who averaged up to 20 drinks a week.The highest group reported downing at least 56 servings of alcohol weekly for an average of eight or more per day.Cancer risks for the mouth and neck sites rose steadily with consumption even for people who reported drinking only with meals.For instance,compared with people in the lowest-consumption group,participants who drank 21 to 34 alcohol servings a week at least doubled their cancer risk for all sites other than the laryngeal cancer. If people in these consumption groups took some of those drinks outside meals,those in the higher consumption group at least quadrupled their risk for oral cavity and esophageal cancers.
People in the highest-consumption group who drank only with meals had 10 times the risk of oral cancer,7 times the risk of pharyngeal cancer,and 16 times the risk of esophageal cancer compared with those who averaged 20 or fewer drinks a week with meals.In contrast,laryngeal cancer risk in the high-intake,with-meals-only group was only triple that in the low-intake consumers who drank with meals.
"Alcohol can inflame tissues.Over time,that inflammation can trigger cancer."Dal Maso says.He suspects that food reduced cancer risk either by partially coating digestive-tract tissues or by scrubbing alcohol off those tissues.He speculates that the reason laryngeal risks were dramatically lower for all study participants traces to the tissue's lower exposure to alcohol.

Approximately how many drinks do the lowest-intake group average per day?
A:3 drinks.
B:8 drinks.
C:20 drinks.
D:56 drinks.

People who sleep for more than eight hours a night do not live as long as those who
sleep for six hours,according to the biggest study yet into sleep patterns and mortality（死
亡率）.
Scientists have no explanation for the findings and do not know if they mean people who
like a lie-in（睡懒觉）can extend their lives by sleeping less.
Although it is a common belief that sleeping for at least eight hours a night is vital for
health and well-being,the six-year study involving more than 1.1 million Americans older
than 30 found that those who slept for less than eight hours were far from doing themselves
any long-term harm.
"Individuals who now average 6.5 hours of sleep a night can be reassured that this is a
safe amount of sleep.From a health standpoint,there is no reason to sleep longer,"said
Daniel Kripke , a professor of psychiatry（精神病学）at the University of California, San
Diego.
Dr. Kripke said,"We don't know if long sleep periods lead to death.Additional studies
are needed to determine if setting your alarm clock earlier will actually improve your health."
The scientists,who were funded by the American Cancer Society,found that the best
survival rates were among the men and women who slept for seven hours a night.Those
who slept for eight hours were 12 per cent more likely to die during the six-year period of the
study,when other factors such as diet and smoking were taken into account.
Even those who spent a mere five hours a night in bed lived longer than those who slept
eight or more hours.However,an increasing death rate was found among those who slept
for less than five hours.
Dr. Kripke said,"Previous sleep studies have indicated that both short-and long-duration
（持续时间）sleep had higher mortality rates. However, none of those studies were large
enough to distinguish the difference between seven and eight hours a night,until now."

Most of the participants slept for 7 hours a night during the study.

Using a computer or smartphone at nightcan cause us to 11 on the pounds, new research has revealed.
The study found a link between blue light 12 --blue light is 13 by smartphones and tables--and increasedhunger. It found that exposure to the light increases hunger levels for severalhours and even increases hunger levels 14 eating a meal.
Results of the US study show thatblue-enriched light exposure, compared with 15 light exposure, was 16 with an increase in hunger that began 15minutes after light onset and was still present almost two hours after themeal. Blue light exposure has also already been shown to decreased 17 in the evening, increasing the risk ofinsomnia.
Study co-author Ivy Cheung, of NorthwesternUniversity in Chicago, said, "A single three-hour exposure toblue-enriched light in the evening 18 impacted hunger andglucose metabolism." "These results are important because theysuggest that 19 environmental light exposure for humansmay represent a novel 20 of influencing food intake patterns andmetabolism."
The study group 21 10 healthy adults with regular sleep and eating schedules who received
22 carbohydrate-rich meals. They completed afour-day trial 23 dim light conditions, which involvedexposure to less than 20 lux during 16 hours 24 and less than three lux duringeight hours of sleep. On day three they were exposed to three hours of 260 lux,blue-enriched light starting 10.5 hours after waking up, and the effects werecompared with dim light exposure on day two.
Ms Cheung said more research is needed todetermine the 25 of action involved in the relationshipbetween light exposure, hunger and metabolism.
