Elizabeth Mitchell's new “Liberty's Torch” is the fascinating story of how the Statue of Liberty came to be. The Statue of Liberty's rough history is explored in “Liberty's Torch”.

    Frederic Auguste Bartholdi is an all-but-forgotten figure in American history. He was, however, responsible for one of the most enduring symbols of the United States: the Statue of Liberty. A Frenchman from Alsace, he designed and built the Statue of Liberty which stood on Bedloe's Island in New York Harbor. How this statue came to be is the fascinating subject of Elizabeth Michell's new book “Liberty's Torch”.

    The power of Mitchell's narrative is convincing(令人信服的). We recognize the Statue of Liberty now as a symbol of hope and opportunity for a nation of immigrants. At the time, though, people could not see that－nor did they even imagine that. Instead, the construction of the statue was born of one man's desire to set up a great monument.

    For this reason, perhaps, “Liberty's Torch” relies on Bartholdi as the connecting thread. Bartholdi went to Egypt to make photographic copies of the main monuments. On the boat, Bartholdi met and began a lifelong relationship with Ferdinand de Lesseps, the man who would build the Suez Canal. Maybe it was this friendship, or maybe it was seeing Egypt's huge monuments, but finally the trip inspired Bartholdi's dream to create the largest statue ever built. Failure to bring this to completion in Egypt, followed by his exile (流放) from Paris, led Bartholdi to sail to America.

    By explaining the Statue of Liberty's hard history and showing Bartholdi's brave spirit, Mitchell has done a great service.

    With the development of science and technology, new inventions, especially new electronic products, have made people's lives easy and convenient. But as the saying puts: A coin has two sides.

    One day, I was walking in the park with a friend and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation.

    The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.

    As almost every contact we can imagine between human beings gets automated, the alienation(疏远) index goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.

    Pumping petrol at the station? Why say good morning to the attendant when you can swipe(刷)your credit card at the pump and save yourself the bother of human contact?

    Making a deposit at the bank? Why talk to a teller who might live in the neighborhood when you can just insert your card into ATM?

    Pretty soon you won't have the burden of making eye contact at the grocery shop. Some supermarket chains are using a self-scanner so you can check yourself out, avoiding those check-out people who look at you and ask how you are doing.

    I am not against modern technology. I own a cell phone, an ATM card, a voice mail system, and an email account. Giving them up isn't wise…they're a great help to us. It's some of their possible consequences that make me feel uneasy.

    More and more, I find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up a call because I didn't really have time to talk. The communications industry devoted to helping me keep in touch is making me lonelier.

    So I've put myself on technology restriction: no instant messaging, with people who live near me，no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.

    I was born on the 17th of November 1828, in the village of Nam Ping, which is about four miles southwest of the Portuguese Colony (殖民地) of Macao, and is located on Pedro Island lying west of Macao, from which it is separated by a channel of half a mile wide.

    As early as 1834, an English lady, Mrs. Gutzlaff, wife of a missionary to China, came to Macao. Supported by the Ladies' Association in London for the promotion of female education in India and the East, she immediately took up the work of starting a girls' school for Chinese girls, which was soon followed by the opening of a boys' school.

    Mrs. Gutzlaff's comprador(买办) happened to come from my village and was actually my father's friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff's school and it was doubtlessly through his influence and means that my father got me admitted into the school. It has always been a mystery to me why my parents should put me into a foreign school, instead of a traditional Confucian school, where my big brother was placed. Most certainly such a step would have been more suitable for Chinese public opinion, taste, and the wants of the country, than to allow me to attend an English school. Moreover, a Chinese belief is the only avenue in China that leads to political promotion, influence, power and wealth. I can only guess that as foreign communication with China was just beginning to grow, my parents hoped that it might be worthwhile to put one of their sons to learning English. In this way he might become an interpreter and have a more advantageous position to enter the business and diplomatic world. I am wondering if that influenced my parents to put me into Mrs. Gutzlaff's School. As to what other sequences it has eventually brought about in my later life, they were entirely left in the hands of God.

    Nelson Mandela is respected and admired around the world. To South Africa he is a superstar. He is a hero who shocked the world by fighting for peace between races, even though he spent 27 years in the prison of the South Africa's white, racist regime(政权).

    Mandela, who won the nation's first all­race elections after the fall of apartheid (种族隔离) in 1994, retired in 1999. But even now, he is as popular as ever.

    His popularity has inspired an entire national industry. His portrait (肖像) has appeared at many places, including on some goods. His face has appeared on a South African coin, a district of a city was named in his honor and some business leaders hope to build a giant statue that looks like him—the Statue of Freedom in celebration of his birthday. It would stand taller than New York's Statue of Liberty.

    His popularity is similar to that of John F. Kennedy in the US or Winston Churchill in Britain, but few politicians today have achieved his level of admiration, said Tom Lodge, head of the Political Science Department of the University of the Witwatersrand.

    "Sometimes it isn't completely appreciated what a skilled performer Mandela has been throughout his political career. He's a very, very clever man."

    However, he is far from perfect.

    Most articles about his birthday, which appeared in every major South African newspaper on the day, briefly mentioned that Mandela did have shortcomings.

    Then they returned to their following praises.

    "Through the ages, the human race has had its icons(偶像)—men and women who rose above ordinary people to inspire their generations," The Mail and Guardian Weekly said, "In our generation, the god brought us Nelson Mandela."

    Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity (湿度).

In very cold climates, there is a constant danger of developing hypothermia, which is a life-threatening drop in core body temperature to below normal levels. The normal temperature for humans is about 37.0℃. However, differences in persons and even the time of day can cause it to be as much as 6℃ higher or lower in healthy individuals. It is also normal for core body temperature to be lower in elderly people. Hypothermia begins to occur when the core body temperature drops to 34.4℃. Below 29.4℃, the body cools more rapidly because its natural temperature regulating system usually fails. The rapid decline in core body temperature is likely to result in death. However, there have been rare cases in which people have been saved after their temperatures had dropped to 13.9-15.6℃. This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes. She was found unconscious, not breathing, and her heart had stopped beating, yet she was eventually saved despite the fact that her temperature had dropped to 13.7℃.

In extremely hot climates or as a result of uncontrollable infections, core body temperatures can rise to equally dangerous levels. This is hyperthermia. Life-threatening hyperthermia typically starts in humans when their temperatures rise to 40.6-41.7℃. Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

    People with an impulsive(冲动的) personality refer to those who tend to do things without considering the possible dangers or problems first. According to a new study by researchers at the University of Georgia, such people may be more likely to have food addiction. The study found that people exhibiting impulsive behavior weren't necessarily overweight, but impulsiveness was related to a direct relationship with food, and therefore, less healthy weight.

    Food addiction has been compared to addictive drug use. Studies have linked the dopamine (多巴胺) release that occurs after tasting delicious food to the dopamine release that happens when people consume other addictive substances.

    Impulsive behavior involves several personality traits (特点). Two of these traits, known as negative urgency and lack of perseverance, were particularly associated with food addiction and high BMI (身体质量指数) during the study.

    Negative urgency is characterized by the tendency to behave impulsively when experiencing negative emotions. Some people might drink alcohol or take drugs. For others, it could mean eating to feel better. Lack of perseverance is when a person has a hard time finishing hard or boring tasks. People with a lack of perseverance might have difficulty attempting to change addictive eating behavior, which could also cause obesity.

    "Impulsiveness might be one reason why some people eat in an addictive way despite motivation to lose weight," said Dr. Ashley Gearhardt, a clinical psychologist. He was involved in developing the Yale Food Addiction Scale in aid of those people. "We are theorizing that if food addiction is really a thing, then our measure, the Yale Food Addiction Scale, should be related to helping control impulsive action," said Gearhardt.

    Clinical psychologist Dr. James MacKillop, whose lab was conducting the study, believes that therapies(治疗，疗法)used to treat addictive drug behavior could help people who suffer from addictive eating habits.

    "Most of the programs for weight loss at this point focus on the most obvious things, which are clearly diet and exercise," MacKillop said. "It seems that managing strong desires to eat would naturally fit in with the skills a person would need to eat healthily."
