学科网（北京）股份有限公司 Unit 1 [Part One] Text Blame your brain It’s a fact: many teenagers take more risks than children and adults. The question is, why ? Check out the latest studies and think about what you can do about it. The “wow” factor Have you ever been on a roller-coaster ride ? How did you feel when you got off ? Excited ? Amazed ? This is the “wow” factor, the feeling of pleasure we get when we take and survive a risk. Scientists know that a brain chemical called dopamine causes this feeling of enjoyment. What has dopamine got to do with you ? Well, some scientists believe that dopamine levels are sometimes lower in teenagers than hey are in children. This means that some teenagers might need to take more risks to get the same “wow” factor. “I just felt like it” Have you ever done something dangerous or frightening without thinking about what happens next ? When an adult asks a teenager, “What were you thinking of when you did that ?” a common reply is, “I just felt like it.” But the question misses the point, because the point is that the teenager might not have been thinking at all ! The teenager didn’t plan to. take a risk: it just “happened”. A few years ago, scientists made a surprising discovery: the teenage brain goes through many physical changes, and some parts of it develop later than others. The last part to fully develop is the frontal cortex. This is the area of the brain which allows us to do things such as controlling feelings and making good decisions. Pressure from friends Have you ever taken a risk to impress your friends ? Even teenagers who are not usually big risk-takers may suddenly do something dangerous because they want to show off or fit in. If you look at statistics, boys often take more risks than girls, perhaps because they don’t want to look bad in front of their friends — though girls dislike that too. Boys are more likely not to wear seat belts, more likely to get into an argument or a fight, and more likely to smoke and drink. But it taking risks really the best way to get people to respect, notice and like you ? What can you do There’s no easy solution, but try to make good choices and be independent. Don’t get pushed into doing things by your friends. You can get your dopamine fix in lots of other exciting ways. Roller coasters, skateboarding and surfing will all give you the same “wow” factor. And if you’re around 17, stop worrying, because your brain has reached the point where you can more easily make wise decisions. You’ve survived up until now, so you’ve achieved a lot — well done !
