Example Input: Article: My 16-year-old son, Anton, had gone to the local swimming hole. Most of the kids who swim there are fit and strong teens, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his well-being. Still, the firefighter's first words, "You need to come up here to the Stillwater River," made me catch my breath. When I got to the river, I saw Anton sitting quietly on a low platform of the fire engine, with a towel wrapped about his shoulders. I hurried over to him. "You OK?" I asked. "Yeah," was all he said. But my eyes begged for an explanation. I didn't get it from my son. The story was this: A couple in their 20s, unfamiliar with the Stillwater, had gotten caught in the current and began screaming for help. Without hesitation Anton and his friend dived into the water, swam out to the drowning woman, and brought her safely to shore. In an age in which the world "hero" is broadcast with abandon and seemingly applied to anyone, I realized the real thing in my son and his friend--the disregarding of personal safety for the sake of another human being. I know that teens are headstrong and self-centered, but this didn't lower the gravity of the event and the desire to do good. Along the way home I tried to get some more information from him, but the only words were, "What's for supper?" I thought twice about the tragedy that might have been. Questions flew across my mind like a flight of swallows: Would I have risked my life to save a drowning person? Or would I have chosen to dial 911? Would I have told the story over and over to anyone who'd listen? The next morning, when Anton got up, I half expected him to tell me the story from his point of view, now that he had some distance from the event. But all he did was to toast a pie, pull himself together, and head for the door to begin the new day.

Example Input: Article: Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Example Input: Article: Making friends in the first few weeks of school is easy. Many students can find a friend in little time. They can be amazed at how close they can get to someone whose interests are completely different, and how comfortable they feel about expressing their mutual fondness. Unusual bonds are one of the great pleasures of school life, and can lead to enriching relationships based on mutual respect. Mostly, though, by a couple of weeks into term, they are really embarrassing. And shaking off friends can be a lot harder than making them. School is all about being busy and trying new things, so you needn't feel too bad about ditching( ......) old friends in favor of new people and experiences. So long as you do it kindly. The pace of school life can be a great excuse for turning down another invitation for a party. You can even claim to be studying---you're at school, and you're supposed to work hard. Another kind way of getting rid of an unwanted friend is to go on inviting them out, but to events where lots of other people will demand your time. Or you could suggest activities that you think they'd enjoy, but which you won't actually be able to make yourself. Then you could say "I'm really busy at the moment. I'll give you a call when I've finished this assignment". But wait. Hasn't someone just said that to you? How do you manage to stay such company that you're not the one being ditched? For a start, concentrate on how interesting the other person is. Remember the things going on in their lives and text or ring to check how they got on with those things. Do sympathize if things have gone badly, and congratulate them if things have gone well. Have a weekly time and place where you meet friends, so that you can invite new friends to drop in. There, the more cheerful you appear, the more popular you are likely to be.
