　　A new study suggests that the more teenagers watch television, the more likely they are to develop depression as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered.
　　The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression. They based their findings on more than four thousand adolescents 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. Media use totaled an average of 5.5 hours a day. More than 2 hours of that was spent watching TV.
　　Seven years later, in 2002, more than 7 percent 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 percent 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 explore if watching TV causes depression. But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and socializing. It might also interfere with sleep, he says, and that could have an influence.

　　Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off and on again when you return. A sensor will detect the presence of a human and turn the systems on, and when the humans leave it will turn them off again.
The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the firemen. It will also call the police, should the sensors detect an intruder（非法闯入者）. You will open the door using your personal card--the one you use for shopping--maybe using a number known only to you.

　　　How men first learnt to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thought and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to present those sounds, and which could be written down. Those sounds, whether spoken or written in letters, we call words.
　　　The power of words, then, lies in their associations - the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certai …… 此处隐藏：5149字，全部文档内容请下载后查看。喜欢就下载吧 ……
