A four-year study of 200 college students found that those who drink heavily and started drinking at an early age demonstrate poor decision-making skills, just like long-term, chronic(长期的) alcoholics. Researchers at the University of Missouri-Columbia believe early onset binge drinking negatively affects psychological development.
The researches examined college students between the ages of 18 and 22. After three years, they tested them using the Iowa Gambling Test, which measures the tendency to make immediate (disadvantageous) or long-term (advantageous) choices.
Based on the students’ reported drinking habits, they were grouped into four categories: low binge drinkers, moderate binge drinkers, increasing binge drinkers and stable or high binge drinkers.
“Students in the stable or high alcohol use category, who had longer histories of binge drinking, made riskier and less advantageous choices, which reflect problems associated with planning for the future,” the researchers reported.
The study also found that only students who started binge drinking when they were younger showed impairment on the task.
“There is reason to think that heavy binge drinking during adolescence, when the brain is still rapidly developing, may have some negative legacy (遗传) on psychological development,” said Kenneth J. Sher of MU’s Midwest Alcoholism Research Center in a news release. “The interesting thing is that if we were to just look at binge drinkers and how impaired they are in the decision-making process as juniors, we’d really be obscuring(使模糊) the important issue, which is how long they’ve been binge drinkers and / or how early they started.”

That' s bad news for backs, necks and shoulders.
"Laptops are basically not designed based on human bodies-unless you' re 2 feet tall," says physician
Norman J. Marcus, a muscle (肌肉 ) specialist in New York City.
When you work at a computer, the keyboard should be at elbow height, so your upper and lower arms
form an angle (角度) of 90 degrees or more. The monitor (显示器) should be at about eye level so you can
rest back in a chair with back support.
But most users simply set their laptops on a desk or table. The keyboard is too high, which makes your
arms reach up, your shoulders rise and your wrists (手腕) bend down. The monitor is too low, which pulls
your head and neck forward and down and this may hurt your back.
That' s OK if you use your laptop occasionally, for short periods. But if you use one for hours without
stopping-as do millions of college students, business travelers, video-gamers and growing numbers of office
workers-you' re setting yourself up for muscle problems that can make your entire upper body hurt.
Experts have warned about laptop problems for years-but without success. People continue to abandon
large and heavy desktops in favor of the smaller and lighter laptops. And WiFi (无线局域网 ) connections let
us use laptops anywhere-in bed, on the floor-and in all kinds of positions.
B. muscle pains are mainly caused by laptops
C. laptops are not suitable for people of usual height
D. laptops cause a lot of diseases easily
B. there are no suitable places for laptops
C. we shall buy desktops instead of laptops
D. desktops will face a hard future
B. People pay little attention to the risks of laptop use.
C. Most people use laptops more often than desktops.
D. Laptops bring people more disadvantages than advantages.
B. tell us people prefer laptops to desktops
C. persuade people not to use laptops any more
D. warn people of health problems caused by laptops
