Article: In the market of luxury brands, Chinese consumers are only second to the Japanese in the world. Across the globe it's clear that the young generation are increasingly relying on expensive brands for their self-image. Personally I am a fashion-lover, at least in spirit. I love to look at clothes and shoes. But I don't understand why people spend large amounts of money on designer labels. Certainly, young people, whether in China or elsewhere, should be building their self-confidence in other ways. When a young woman shows off a handbag worth two months' salary, that's a scary thing. What are the psychological factors forcing young people to take on debt for designer items? The desire to say, "Hey, look at me. I'm wealthy. I have social status." Scientists have found the acquisition of luxury brands doesn't lead to happiness. Study after study has shown that, although we are born to desire material possessions, when we get them, we don't suddenly become "happy people". In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, have shown that individuals who invest in travel and other experiences get more pleasure than those who invest in material things. That's because experiences are more easily combined into a person's identity. If I travel to Yunnan, that adventure affects how I think. My memories entertain my friends and colleagues. It follows, then, that investing in experiences improves my chances for successful social relationships. Moreover, as Van Boven has observed, young people who pursue happiness through "things" are liked less by others than young people who seek happiness through experiences. This research is pretty solid, but I suspect it won't persuade young people not to desire a style. It's natural to want to express yourself through your appearance. So my advice is, create a look that isn't tied to a designer label. You don't have to _ to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.

Article: Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry . Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports. Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
Question: What is said about the average American in the passage?

Article: When I was in elementary school, my teachers would always complain about my behavior in class. There was no doubt that I had a great deal of energy, and therefore I was always talking with my classmates and not paying attention to the lessons, which my teacher _ to see. If you don't believe me, the comments on my report cards every year can tell the story. In my third year in elementary school, my teacher wrote, " Neil should tend to have a more serious attitude towards his schoolwork." And in my fifth year in elementary school, my teacher wrote, " Neil is not a bit strict with his work, his compositions as well as his notebook and so on. He has to be encouraged and urged by his parents or teachers." After only a few months, my sixth-grade teacher wrote, " Less social involvement and more academic diligence is in order." Later that same school year, my sixth-grade teacher noticed that all my book reports were about the universe. Knowing that I had a lot of extra energy, she recommended that I should take advanced after-school classes about the universe at the Hayden Planetarium. From then on, my love of the universe became stronger and stronger. Instead of killing my time in class, I focused my extra energy on the subject that would be bound to become my career. Between the ages of eleven and seventeen, I took about eight courses on the universe. For each one, I received an attractive certificate of completion, signed by both the teacher and the head of the Hayden Planetarium. We still offer these classes today. And we still give out certificates of completion, which are signed by the teacher and, of course, the head --- me. I am the head of the Hayden Planetarium. And I am also the head of a associate of the Department of Astrophysics at the American Museum of Natural History. Both of them are in New York City. Welcome to take extra classes here.
