5．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 13-16to find out the relationship between media（媒体） use and depression．They based their findings on more than 4000young 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 2hours 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．

From 8：30pm to 9：30pm on Saturday，March 26th，2011，a g reat number of people around the world turned off the lights for Earth Hour．It is a bit like an environmental New Year，providing a chance to help care for our earth and make people around the world learn how important it is to do that．What can do during this hour？We can do lots of run things in the dark，such as planning a candlelight dinner for our family or a group of friends，telling stories and singing songs with the kids and neighbors． What did you do for Earth Hour this year？Let's share the Earth Hour stories． |
Emma I was on one of the mountains near the city and took photos of my city．It was great to watch the stars and the moon after a busy day so that I could enjoy this relaxing moment． |
Albert I work as a waiter in a restaurant．Our restaurant was still open even for Earth Hour as we got lots of reservations （预定） that night．So we spent the hour working by candlelight．And guess what？Our customers loved that and promised to come for next Earth Hour． |
Brandon I turned off the main power to my house and went for a walk for Earth Hour．It was a little strange to walk in the dark，but it was only for one hour．Just think of what it must have been like before the invention of the light bulb! |
Mary I invited my friends who know and support Earth Hour activities．We actually had a candlelight concert and we talked about the old happy days that we spent together in college． |
