    Peter loved to shop used articles. Almost a month ago, he bought popular word game that used little pieces of wood with different letters on them. As he was purchasing it, the salesgirl said, “Uh, look, the game box haven’t even been opened yet. That might be worth some money. ”
    Peter examined the box, and, sure enough, it was completely covered in factory-sealed plastic. And he saw a date of 1973 on the back of the box.
    “You should put that up for auction (拍卖) on the Internet, and see what happens.”the salesgirl said.
    “Yes, you’re right. People like something rare.” Peter agreed, “I can’t imagine there being very many unopened boxes of this game still around 40 years later.”
    “Don’t forget to tell me if you sell it.” the salesgirl smiled.
    “No problem.” Peter said.
    After he got home, Peter went online to several auction websites looking for his game. But he couldn’t find it. Then he typed in the name of the word game and hit Search. The search result was 543 websites containing information about the changes of the game. Over the years, the game had been produced using letters in different sizes and game boards in different colors. He also found some lists of game fans looking for various versions of the game. Peter emailed some of them, telling them what he had.
    Two weeks later, Peter went back to the shop.
    “Hello. Do you still remember the unopened word game?”
    The salesgirl looked at him for a second, then recognized him and said, “Oh, hi!”
    “I’ve got something for you,” Peter said. “I sold the game and made $1,000. Thank you for your suggestion.” He handed her three $ 100 bills.
    “Wow!” the salesgirl cried out. “Thank you, I never expected it.”

    When I was nine years old, I loved to go fishing with my dad. But the only thing that wasn’t very fun about it was that he could catch many fish while I couldn’t catch anything. I usually got pretty upset and kept asking him why. He always answered, “Son, if you want to catch a fish, you have to think like a fish”, I remember being even more upset then because, “I’m not a fish!” I didn’t know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?
    As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don’t have any eyelids(眼皮) and the sun huts their eyes… The more I understood fish, the more I became effective at finding and catching them..
    When I grew up and entered the business world, I remember hearing my first boss say, “We all need to think like sales people.” But it didn’t completely make sense. My dad never once said, “If you want to catch a fish you need to think like a fisherman.” What he said was, “You need to think like a fish.” Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.

    Daniel Anderson, a famous psychologist, believes it’s important to distinguish television’s influences on children from those of the family. We tend to blame TV, he says, for problems it doesn’t really cause, overlooking our own roles in shaping children’s minds.
    One traditional belief about television is that it reduces a child’s ability to think and to understand the world. While watching TV, children do not merely absorb words and images (影像). Instead, they learn both explicit and hidden meanings from what they see. Actually, children learn early the psychology of characters in TV shows. Furthermore, as many teachers agree, children understand far more when parents watch TV with them, explaining new words and ideas. Yet, most parents use an educational program as a chance to park their kids in front of the set and do something in another room.
    Another argument against television is that it replaces reading as a form of entertainment. But according to Anderson, the amount of time spent watching television is not related to reading ability. TV doesn’t take the place of reading for most children; it takes the place of similar sorts of recreation, such as listening to the radio and playing sports. Things like parents’ educational background have a stronger influence on a child’s reading. “A child’s reading ability is best predicted by how much a parent reads.” Anderson says.
    Traditional wisdom also has it that heavy television-watching lowers IQ (智商) scores and affects school performance. But here, too, Anderson notes that no studies have proved it. In fact, research suggests that it’s the other way around. “If you’re smart young, you’ll watch less TV when you’re older,” Anderson says. Yet, people of lower IQ tend to be lifelong television viewers.
    For years researchers have attempted to show that television is dangerous to children. However, by showing that television promotes none of the dangerous effects as conventionally believed, Anderson suggests that television cannot be condemned without considering other influences.

    It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.
    In recent years, many writers have begun to speak the 'decline of class' and 'classless society' in Britain. And in modern day consumer society everyone is considered to be middle class.
    But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an important part of British society. Britain seems to have a love of stratification.
    One unchanging aspect of a British person's class position is accent. The words a person speaks tell her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice, Most people said this accent sounded 'educated' and 'soft'. The accents placed at the bottom in this study, on the other hand, were regional（地区的）city accents. These accents were seen as 'common' and 'ugly'. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.
    In recent years, however, young upper middle-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song 'Common People' puts forward the view that though a middle-class person may 'want to live like common people' they can never appreciate the reality of a working-class life.

    On the first day of her work, Sally found that a class full of problems was waiting for her. Six teachers had quit before her. When she walked in to the classroom, it was chaos: two boys were fighting in the far corner, yet the rest of the class seemed not to notice them; some girls were chatting and some were running about; paper, food packages and other garbage were littered around.... Just when she was about to speak, a student rushed in and pushed her aside! He was twenty minutes late!
    Sally walked onto the platform, picked up a piece of chalk and wrote on the blackboard: “Rule 1: We are family! “ All students stopped to look at her. And she continued with Rule 2, Rule 3… In the following weeks, Sally worked out 10 class rules and posted them on the walls of the classroom. She patiently explained all the rules to the students and require everyone to follow them.
    Surprisingly, Sally was not driven out like the former teachers; instead, she won respect from the students. Over the year, she witnessed gradual change in the class. At the graduation ceremony, just as she expected, she was very proud to stand with a class of care, manners and confidence.
