Decision—thinking is not unlike poker—it often matters not only what you think, but also what others think you think what you think they think you think. The mental process(过程) is similar. Naturally, this card game has often been of considerable interest to people who are, by any standards, good thinkers.

    The great mathematician John von Neumann was one of the founders of game theory. In particular, he showed that all games fall into two classes; there are what he called games of 'perfect information', games like chess where the players can't hide anything or play tricks; they don't win by chance, but by means of logic and skills. Then there are games of 'imperfect information', like poker, in which it is impossible to know in advance that one course of action is better than another.

    One mistaken idea about business is that it can be treated as a game of perfect information. Quite the reverse Business, life itself are games which we must normally play with very imperfect information. Business decisions are often made with many unknown and unknowable factors(因素), best poker players. But few business people find it comfortable to admit that they are taking a chance, and many still prefer to believe that they are playing chess, not poker.

    I came to study in the United States a year ago .Yet I did not know the real American society until I was injured in a car accident because after the accident I had to see a doctor and go to court.

    After the accident .my roommate called a doctor for me. I was very grateful and determined to repay him one day. But the next day, he asked me to pay him $200 for what he had done. I was astonished. He had good reason to charge me, he said. And if I wanted to collect money from the person who was responsible for my injury, I'd have to have a good lawyer. And only a good doctor can help me get a good lawyer. Now that he had helped me find a good doctor, it was only fair that I should pay him.

    But every day I went to see the doctor, I had to wait about 50 minutes. He would see two or three patients at the same time, and often stop treating one so as to see another. Yet he charged me $115 each time .The final examination report consisted of ten lines, and it cost me $215.

    My lawyer was all smiles the first time we met. But after that he avoided seeing me at all. He knew very well the other party was responsible for the accident, yet he hardly did anything. He simply waited to collect his money. He was so irresponsible that I decided to dismiss him. And he made me pay him $770.

    Now I had to act as my own lawyer. Due to my inexperience, I told the insurance company the date I was leaving America. Knowing that, they played for time…and I left without getting a cent.

    For World Heritage(遗产) Sites, you probably think of places connected with ancient art and culture, and historical buildings. But there are a few of the more unusual sites.

    Citadel of Haiti.

    These monuments were built at the end of the nineteenth century when Haiti became independent and the many thousands of black slaves in Haiti were free for the first time. These ex-slaves built the monuments, which The World Heritage List (WHL) describes as a true symbol of liberty.

    The Darjeeling Himalayan Railway in India.

    This railway was opened in 1881 and is still operating today. It crosses a difficult area of mountain landscape and it is a great example of railway engineering. The WHL says that it is the first and still the most outstanding example of a hill passenger railway.

    Borders of France and Spain.

    This is an area of great natural beauty and the mountains have many interesting geological shapes. Besides, people there still use a type of agriculture that used to be common in mountainous areas of Europe but has almost completely disappeared in modern times. The WHL says it shows us about past European society through its landscape of villages, fields and mountain roads.

    Alto Douro, Portugal.

    This is an area in the North of Portugal where wine has been produced for thousands of years. Nowadays it is world-famous for the port wine that is produced there. The WHL says that this long tradition of wine making has produced a cultural landscape of outstanding beauty that reflects its technological, social and economic development little by little.

    One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem， while the student claimed a perfect score. I was elected as their arbiter. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer(气压计).” The student had answered: “Take the barometer to the top of the building，attach a long rope to it，lower it to the street， and then bring it up, measuring the length of the rope. The length of it is the height of the building. ”

    The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and clashed off one, which read： “Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula (公式）to calculate the height of the building. ”

    At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others ，and then added “Probably the best is to take the barometer to the administrator and said to him，' Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.，”

    Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.

    The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.

    Janet Guthrie and Danica Patrick, first female Indy competitor and winner

    No complaints about woman drivers. Janet Guthrie, an space engineer who was training to be an astronaut, turned to car racing when she was cut from the space program for not having completed her doctors degree. In 1977, Guthrie became the first female Indy 500 competitor. She didn't take the lead, but Danica Patrick did. In 2005 and in 2008, Patrick became the first woman ever to win an Indy Car Series.

    Raymonde de Laroche, first female licensed pilot

    A former actress who'd been born Elise Raymonde Deroche in Paris in 1882, Raymonde de Laroche was inspired to take up flying after seeing the Wright Brothers flight demonstrations in 1907 in France. Though she wasn't the first female pilot, de Laroche was the first woman to earn a pilot's license in 1910.

    Gertrude Ederle, first woman to swim across the English Channel

    On August 6. 1926. Gertrude Caroline Ederle became the first woman to swim across the English Channel. Ederle, who lived to be 98 and died in 2003, was also an Olympic swim champion and five-time world record-holder in five swimming events

    Kathrine Switzer, Nina Kuscik and Joan Benoit, first major female marathoners.

    In 1967, 20-year-old Kathrine Switzer became the first woman to run in the Boston Marathon, even though race officials had tried to stop her. Nina Kuscik became the first woman to officially win the Boston Marathon, 1972. In 1984, American Joan Benoit became the first winner of the Women's Olympic Marathon, finishing 400 meters ahead of Norway's Grete Waitz.

    Science has a lot of uses. It can uncover laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation(诱惑) to drag it into problems where it may not be helpful. David Brooks, author of The Social Animal: The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation.

    Brooks gained fame for several books. His latest book The Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't?

    To answer these questions, Brooks surveys a wide range of disciplines(学科). Considering this, you might expect the book to be a dry recitation of facts. But Brooks has structured his book in an unorthodox(非常规的), and perhaps unfortunate, way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters.

    On the whole, Brooks' story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong or memorable characters, the more serious problems with The Social Animal lie elsewhere. These problems partly involve Brooks' attempt to translate his tale into science.
