These days, teenagers are heavily influenced(受影响)by the media. Many of them have watched tof hours of TV. That's more time than they spend wteachers at school, not to mention the time spent on the Internet and newspapers.
However, several studies have shown a serious p: today's teenagers don't have good media literacy(媒体素养). In other words, they have difficulty critically(批判地)thinking about the ithey see. One study that was done on middle school students showed that more than 80 percent of them c tell the difference between real stories and ads that look like news.
Stanford professor Kevin John teaches a class called Media Effects. He tries to help his students learn media literacy. The professor gave an ethat shows why media literacy is important. In the example, two news stations report a snowstorm. One focus on(关注)the terrible road c. The other focuses on kids playing in the snow. "With a new story, news stations tell you what they feel are the important details." said John. "A person who has media literacy would realize that each story is about one side at this time. There is more going on."
Some experts think s is the best place to teach media literacy. Others believe everyone from parents to reporters should help teenagers learn these s. As for the best time to start learning media literacy, many experts suggest(推荐)the age of 12. But some basic ideas can be taught even e."It's never too early to start learning media literacy," John said.
