Article: The London Marathon celebrates its 32nd birthday. That is 32 years of stresses and anxieties, blisters and painful knees, and tales that are hard to believe. Somehow, I've managed to run four of _ . And I have medals to prove it. It seemed like a good idea at the time. I watched the first London Marathon on March 29th, 1981. It seemed extraordinary that normal people would want to run 26 miles and 385 yards. And, it must be said that they looked strange and not quite steady at the end of it all. There are, indeed, terrible tales of people losing consciousness when they reach the finishing line. But it drew all my attention. I knew I had to do it. Three years later I was living in London, not far from Greenwich where the event begins, and it seemed the perfect opportunity to give it a go. I was only a short train ride from the starting line, but more than 26 miles from the finish. "Who cares?" I thought. By the end I did. The moment I crossed that finishing line and had that medal placed around my neck was one of the finest in my life. The sense of achievement was great. Knowing that I'd run a Marathon felt extremely good. London provides one of the easiest of all the officially approved marathons because most of its course is flat. Yes, there are the cobblestones while running through the Tower of London, and there are the quiet patches where crowds are thin and you are crying out for some encouragement -- those things matter to the "fun" runners like myself, but the serious runners don't think of such things. Since 1981,almost half a million people have completed the London Marathon, raising more than $ 125 million for charity. For the majority of the runners, this is what it is all about. It is for charity, for fun, for self-development. I have always loved it. It's crazy, and it's one of the greatest things I've ever done. If you want to feel as though you've achieved something, run a marathon.
Answer: Greenwich.

Article: Having a teenager at home can be a real headache. Many teenagers smoke, drink and even fight. They often do something dangerous. Earlier studies have shown that teenagers are more likely to make _ decisions than people from any other age group, including children and adults. Is it that teenagers are too young to tell right from wrong? Not really. So what's the reason? According to Laurence, a teacher from a US university, the reason is that teenagers care a lot about how their peers view them--that is "peer influence". As children enter their teenage years, they spend more time with their friends and classmates, and also they care more about what they think of them. This makes teenagers make decisions without thinking about the costs. In a test, a group of teenagers were asked to play a video driving game. When they played with their friends watching around them, they took more chances and drove more carelessly because that would increase their possibility of winning. But when they played alone, they drove more safely. Why do peers have such a big influence on teens' behavior? As Laurence sees it, a teenager's brain is like a car with a good accelerator but a weak brake . The "accelerator" is fully developed by teenage years while the "brake" is still not fully developed. When teenagers are watched by their peers, they usually push hard on the accelerator. With their weak brake, it is likely that they are going to end up in an accident. But the good news is that a violent teenager doesn't necessarily become a violent adult. About two-thirds to three-quarters of violent youth grow out of it. "They get more self-controlled."
Answer: They care a lot about what their peers think of them.
