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.

Feeling lonely can make you sick. Doctors have long known that loneliness can cause many health problems and even death. What they didn’t know is   16   this feeling causes illness. A study in the online magazine Genome Biology   17   that loneliness actually influences the important part of our bodies—our genes.

In a small population of patients, researchers   18   more than 20,000 genes to compare how the genes of lonely and non-lonely individuals (个体) express themselves in molecular processes (分子过程) and in personal health. They found that gene expression is   19   in chronically (长期地) lonely people. “We now have a new way for understanding the relationship   20    social experience and physical health,” explains the study’s lead author, Steve Cole of University of California, Los Angeles.

“This study—the first to link (联系)   21   with gene changes—is special and exciting,” says Emma Adam, a professor of human development at Northwestern University. “It   22   in the black box.”

According to John Cacioppo, an author of the study from the University of Chicago, the

work suggests that loneliness is a warning   23  , much like physical pain. “This feeling is so bad because   24   of us wants to be forgotten; that’ s also what human means,” he says. “It makes us   25   for other people and want to be with friends when we’re lonely.”

As a teenager, I am often asked what I am going to be in the future. A lawyer? A doctor? Or a scientist? No, my ideal career is to be a teacher. One of the  1. for that is I want to be a teacher like Mr. Chen.

“Look! Do you know what it is? A-ha, it’s the   2.  ! And it will always move around the sun.” Mr. Chen said and pointed to his head. He then touched the nose and   3.  , “Can you tell me the name of this mountain? It is the highest mountain on Earth! What’s the   4. of it? Yes, it’s 8844.43 metres…” I’ll never forget my first geography lesson. He was   5. humorous that we all fell in love with his lessons   6. . It’s Mr. Chen who opened the door of geography for us.

Generally speaking, most of the teachers are strict 7. students and sometimes a little bit demanding（苛求的）, not so with Mr. Chen. He is a lighthouse, showing us the way to the treasure of knowledge. He is a friend and easy to get   8.  with, always encouraging us to speak out loud without  9. our shyness and other disadvantages. He is an example, volunteering his time to students and other teachers.

One day I happened to meet him in the hospital. Seeing the cut on his arm, I realized he was donating his  10. . I was moved and was   11.  another lesson, a lesson of love and devotion.

Every time I see my globe（地球仪）, it would  12. me of Mr. Chen. He is the most unforgettable teacher I have   13. met and he will always be. Someday I hope I am   14.    to be a teacher like him.

Thank you, Mr Chen, thank you for making learning not a job but a joy.

Thank you for helping me to discover what I do best and to do it even   15.Thank you for understanding all of us and giving us the time and care each of us needs.
