     A new study suggests that the more teenagers watch television, the more likely they are to develop
depression (抑郁症) as young adults.
     The researchers used a national long-term survey of healthy young teenagers of about 13-16 to find
out the relationship between media (媒体) use and depression. They based their findings on more than
4000 young teenagers who were not depressed when the survey began in 1995.
    As part of the survey, the young people were asked how many hours of television or videos they
watched daily. They were also asked how often they played computer games and listened to the radio.
Here was the result. The young people spent five and a half hours a day using media and more than 2
hours of that was spent watching TV.
    Seven years later, in 2001, more than 7% of the young people had signs of depression. The average
age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author
of the new study. He says every extra hour of television meant an 8% increase in the chances of developing
signs of depression.
     The researchers say they did not find any such relationship with the use of other media such as movies,
video games or radio. But the study did find that young men were more likely than young women to develop
depression given the same amount of media use.
     Doctor Primack says the study did not find out if watching TV causes depression directly. But one
possibility, he says, is that it may take time away from activities that could help prevent depression, like
sports and social activities. It might also prevent a person from sleeping well, he says, and that could have
an influence.
     The study was just published in the Archives of General Psychiatry.
     In December, the journal Social Indicators Research published a study of activities that help lead to happy
lives. Researchers from the University of Maryland found that people who describe themselves as happy
spend less time watching television than unhappy people. The study found that happy people are more likely
to be socially active, to read, attend social services and to vote.

Do you think that French fries are really French? French fries are called "pommes frites" in France and they are not from France. French fries come from Belgium(比利时) originally. French fries are made of potatoes, and they are cut and fried. The fried potatoes are called French fries because they were fist seen by Americans in Belgium, but they were fried in the French way. The French way is to fry potatoes twice with a small pause in the middle.

During World War I, there were a lot of hungry American soldiers in Northern France and Belgium. They ate French fries in Belgium. After the war was over, the soldiers went back home to America. However, they missed French fries so much that they made French fries at home. That's how French fries were fist introduced to America.

French fries were called Belgian fries once, but the name was finally changed to French fries. Sometimes French fries are just called fries.

French fries are one of the most popular potato foods in America. American fast food restaurants such as McDonald's and Burger King have French fries on their menus. French fries are freshly fried, and usually served with hamburgers.

If you visit any fast food restaurant in America and order a hamburger, you will probably hear "You want fries with that?"Why don't you think about the history of French fries a little while, and say "Yes, please. Thank you."
