    Dr Wiseman started “the laugh lab” project in September 2001. It is the largest study of humour. Participants（This is a subject that has long attracted psychologists and philosophers. Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves. By December 2001 over 10, 000 jokes had been submitted. This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humour, for instance.

    Dr. Wiseman. “Males use humour to appear superior to others, while women are more skilled in languages and prefer word play. ”

    Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called “toilet humour”. But the French like their jokes short and sharp: “You're a high priced lawyer. Will you answer two questions for $500?” “Yes. What's the second question?”

    The Germans are famous for not having a sense of humour. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality.

     Perhaps that proves the point. Is this joke funny? I don't know, but let's say yes, just to be safe. Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.

    John was part of my childhood growing up in the 1970s and a link to sunny, fun-filled days spent on the beach at Bangor in Northern Ireland where we went for our summer holidays. To many, he was a mystery. Every afternoon John would wander to the end of the pier (码头) where he fed the seagulls and delighted in the sound of their excited cries as they flew around his head.

    Often I asked my family questions regarding John. Eventually I gave up as no one could tell me anything about him. As I grew up, my visits to the beach became less frequent, and my memories of John buried in a child's imagination.

    Last year memories came flooding back as I walked along the coastline, where I noticed a lady feeding the seagulls on the pier, and I decided to introduce myself. Then I came to know that the lady was John's daughter, and after John left this world she carried out the ritual (惯例), which had held such importance for her father.

    In some strange way I felt we shared a bond, each needing to remember. In return, Lucy told me of John's life, his days in the British Navy (海军) during World War I and how he almost lost hope when his ship was attacked by a German U-boat in the North Sea and he found himself in a lifeboat with five others.

    Close to death, he thought he heard the sound of wings. He put up his hands, only to catch a seagull that had landed on the side of the boat. The seagull saved the lives of the six men as it was used to catch fish, which kept them alive until they reached land. This period of John's life was one he never talked about. But the ritual he first performed as a young man remained a part of him until he died.

    Now I visit Lucy as often as I can, just to chat or very often walk along the beach to the pier end. We enjoy the comfortable silence, each lost in special memories.

    My friend's grandfather came to America from a farm in Thailand. After arriving in New York, he went into a cafeteria(自助餐厅) in Manhattan to get something to eat. He sat down at an empty table and waited for someone to take his order. Of course nobody did. Finally, a woman with a big plate full of food came up to him. She sat down opposite him and told him how a cafeteria worked.

    “Start out at that end,” she said, “Just go along the line and choose what you want. At the other end they'll tell you how much you have to pay.”

    “I soon learned that's how everything works in America,” the grandfather told my friend later, “Life's a cafeteria here. You can get anything you want as long as you want to pay the price. You can even get success, but you'll never get it if you wait for someone to bring it to you. You have to get up and get it yourself.”

    When I was in the eighth grade, one caring teacher of mine taught me several useful little techniques. He told me to keep a notebook nearby when I was reading and that I should try to figure out what the main idea of every paragraph was so that I could understand the passages better. It seemed awfully boring at that time, but I decided to give it a try anyway.

    It didn't take long before I started reading a book called How to Read a Book that would completely change how I thought about the written word. Thanks to these techniques, I learned to get the most out of reading. I kept applying them over the years until I finally came up with a lot of little techniques for reading a book.

    I also eventually came to learn that there were a lot of different kinds of reading. For example, when I read a Stephen King novel, the interesting plot made me completely relaxed. Then there's reading to learn new things, which is what I do when I read personal finance books. There's also reading to understand and grow, which is easily the hardest and the most rewarding. The last kind of reading involves taking a piece of literature or a nonfiction book that you might read for simple pleasure and transforming it into something life-changing, or something that causes you to question some of your deeply-held ideas and beliefs.

    How to Read a Book really focuses on the latter two: books that you read to learn about a new topic or to learn a skill, and books that you read to learn about yourself. If you've ever been drawn to read to really improve yourself, this book is well worth the time to read even if it's a bit dry at times. Let's dig in.

    Michelle Kwan was born on July 7, 1980, in Torrance, California. The daughter of Hong Kong immigrants (移民), Kwan watched her older brother play ice hockey as a kid. She began skating when she was five, and entered and won her first figure skating competition at seven. She won the world title in the 1994 World Championships at the age of 13, and earned a spot as an alternate (候补者) for the 1994 Olympic Games. Kwan went on to capture the world title in 1996, 1998, 2000, 2001 and 2003.

    At the Nagano Winter Olympics in 1998, Kwan was believed to win gold, but ended up with a disappointing silver medal when fellow US skater Tara Lipinski surprisingly took first place. Shortly before the Salt Lake City Winter Olympics in 2002, Kwan, who was then the reigning world champ, surprisingly fired both her choreographer (编舞者), Lori Nichol, and longtime coach, Frank Carroll. Once again, she failed to get the gold medal when she finished third behind Irina Slutskaya of Russia and US skater Sarah Hughes, who took first.

    As a student at the University of California at Los Angeles, Kwan has continued to compete since her defeat (战败) in Salt Lake City. In February 2006, she was unable to take part in the Olympic Games in Torino, Italy because of a serious injury. Though Michelle Kwan did not compete during the 2006－2007 figure skating season, she has turned down an offer to work for NBC Sports and says she is not retiring.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play has an important part in keeping you healthy.

    Use "the best medicine" to treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.

    Anyway, adding humor, laughter, and play to our life will influence us mentally, physically and socially and bring us many advantages. So we should make full use of humor, laughter and play to make our life more active, interesting and happier.
