Do you believe that things are connected for no scientific reason at all? For example, do you avoid saying the word "four" to avoid bad luck? If so, you have a superstition (迷信). And you're not alone – all kinds of people have them.

For example, Portugal's soccer superstar Cristiano Ronaldo always steps onto the pitch (球场) with his right foot first, according to The Telegraph. And sports players are not alone in having superstitions. A visitor once asked the Nobel Prize winning scientist Niels Bohr whether he really believed that the horseshoe he'd hung at his country home was lucky. "Of course not," the Danish physicist said. "But I understand it's lucky whether you believe in it or not."

One recent study found that even scientists at MIT and other top US schools tended to look for a meaning in natural events, similar to the connection between stepping on the pitch and playing soccer well, according to The Atlantic. When the researchers gave the scientists little time to answer questions, they were twice as likely to agree with statements such as "Trees produce oxygen so that animals can breathe" as they were when they had more time to think about their reply.

It seems that fear can make people think differently in this way, too. In a British study, students imagined meeting a "witch" who said she would cast (施魔法) an evil spell(符咒) on them. About half said a scientist should not be worried about the spell. Yet each of them said that, personally, they wouldn't let the witch do it to them.

So why are so many of us superstitious? Well, it seems to be our way of dealing with the unknown. "Many people quite simply just want to believe," Brian Crank, a professor of psychology at Missouri Western State University, said in a 2008 interview. "The human brain is always trying to work out why things happen, and when the reason is not clear, we tend to make up some pretty bizarre (古怪的) explanations."

    And these explanations aren't completely unhelpful. In fact, superstitions can sometimes work and bring real luck, according to psychologists at the University of Cologne in Germany in the May 2010 issue of the journal Psychological Science. They found that believing in something can improve performance on a task like an exam.

    So, what about you? What superstitions do you follow to keep you safe and successful?

    Born in Detroit, Michigan, on January 10, 1928. Philip Levine was formally educated in the Detroit public school system. After graduation from university, Levine worked a number of industrial jobs, including the night work in factories, reading and writing poems in his off hours. In 1953, he studied at the University of Iowa. There, Levine met Robert Lowell and John Berryman, whom Levine called his "one great guide."

    About writing poems, Levine wrote: "I believed even then that if I could change my experience into poems I would give it the value and honor that it did not begin to have on its own. I thought too that if I could write about it, I could come to understand it: I believed that if I could understand my life-or at least the part my work played in it-I could write it with some degree of joy, something obviously missing from my life."

    Levine published (出版)his first collection of poems. On the Edge in 1961, followed by Not This Pig in 1968. Throughout his life. Levine published many books of poems, winning many prizes. A review said: "Levine writes poems about the bravery of men, physical labor, simple pleasures and strong feelings, often set in working-class Detroit or in central California, where he worked or lived."

    He taught for many years at California State University, Fresno, and served as Distinguished Poet in Residence for the Creative Writing Program at New York University. After retiring from teaching, Levine divided his time between Brooklyn, New York, and Fresno, California, until his death on February 14, 2015. His final poem collection, The Last Shift, as well as a collection of essays(短文)and other writings, My Lost Poets, A Life in Poetry, were published in 2016.

    Hobbs was an orphan(孤儿). He worked in a factory and every day he got a little money. Hard work changed him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.

   One day the lawyer said to him, "One thousand dollars, and here is the money." As Hobbs took the package of notes, he was very dumbfounded (惊呆的). He didn't know where the money came from and how to spend it. He said to himself, "I could go to find a hotel and live like a rich man for a few days; or I give up my work in the factory and do what I'd like to do: painting pictures I could do that for a few weeks, but what would I do after that? I should have lost my place of the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting pictures. But it's too much for one and too little for the other."

    "Here is the reading of your uncle's will," said the lawyer, "telling what is to be done with this money after his death. I must ask you to remember one point. Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it."

    "Yes, I see. I'll do that." said the young man.

    I'M Pei, the Chinese-American, who was regarded as one of the last great modernist architects, has died at the age of 102.

    Although he worked mostly in the United States, Pei will always be remembered for a European project: His redevelopment of the Louvre Museum in Paris in the 1980s. He gave us the glass and metal pyramid in the main courtyard, along with three smaller pyramids and a vast subterranean (地下的) addition to the museum entrance.

    Pei was the first foreign architect to work on the Louvre in its long history, and initially his designs were fiercely opposed. But in the end, the French — and everyone else — were won over. Winning the fifth Pritzker Architecture Prize in 1983, he was thought as giving the 20th century "some of its most beautiful inside spaces and outside forms … His talent and skill in the use of materials approach the level of poetry."

    After studying architecture at the Massachusetts Institute of Technology and Harvard, Pei set up his own architectural practice in New York in 1955.

    Designing the John F. Kennedy Presidential Library & Museum in 1964 established him as a name. His East Building of the National Gallery of Art in Washington in 1978 changed people's ideas of a museum. The site was an odd trapezoid (梯形) shape. Pei's solution was to cut it in two. The resulting building was dramatic, light and elegant — one of the first crowd-pleasing cathedrals of modern art.

    Though known as a modernist, and notable for his forms based on arrangements of simple geometric (几何的) shapes, he once urged Chinese architects to look more to their architectural tradition rather than designing in a western style.

    In person, I.M. Pei was good-humored, charming and unusually modest. His working process was evolutionary, but innovation (创新) was never an intended goal.

    "Stylistic originality is not my purpose," he said. "I want to find the originality in the time, the place and the problem."
