The Great Pyramid(金字塔)was built nearly 5,000 years ago for a king called Khufu. It is on the west bank of the Nile River. In fact, all the pyramids along the Nile River are on its west bank. The ancient Egyptians thought of the rising of the sun as the beginning of life and the setting of the sun as the end of life. This is why their bodies were buried on the west of the Nile.

    It is very hard to realize just how big the Great pyramid is. It has over 2,000,000 pieces of stones. Most of these big stones weigh two and a half tons each. Some even weigh fifteen tons. Without machinery, the ancient Egyptians cut and moved and lifted each of these stones. Almost all the stones came from the east bank of the Nile, and they were taken across the river in boat. It took more than 100,000 people twenty years to build the Great Pyramid.

    The Great Pyramid is over 450 feet high today. Each of the sides of the Pyramid is 755 feet long. It takes about twenty minutes to walk all the way around it.

    China's cancer researcher Zhu Chen, together with two French researchers Anne Dejean and Hugues de Thé, received Sjoberg Prize 2018 in Stockholm Concert Hall, Sweden on Friday.

    “We used wisdom from both Chinese and Western medicine and offered a cure to one of the most deadly cancers,” Chen told Xinhua, “I feel that Chinese medicine has potential to contribute more to human health. It struggles for benefiting all mankind. It's a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.

    This year's Sjoberg winners have developed a new and targeted treatment for a specific form of blood cancer called acute promyelocytic leukaemia (急性早幼粒白血病). It was once one of the deadliest forms of cancer, but it is now possible to cure nine out of ten patients who receive the new treatment. The winners have made this revolutionary development possible by methodically mapping the molecular mechanisms responsible for the disease.

    The Prize is awarded by the Royal Swedish Academy of Sciences and is funded (资助)by the Sjoberg Foundation. The foundation, with a donation of 2.5 billion US dollars, was founded in 2016, and serves to promote scientific research that focuses on cancer, health and the environment.

    The Prize is an annual international prize in cancer research awarded to individual researchers or research groups. The prize amounts to one million US dollars, of which 100,000US dollars is the prize sum and 900,000US dollars is funding for future research.

    He is a lesson to every boy who ever picked up a basketball and dreamed that it would change his life.

    The lights were never brighter and the crowds were never bigger for a homegrown sports hero than they were a quarter-century ago for Ray Hall. But his athletic achievements, as impressive as they are, are to my mind not what is most admirable about the man.

    Known as “Sugar Ray” in his teens, Hall was rated among the country's top 25 high school basketball players. An inner-city kid from a solid family, Hall took on the challenge of lifting Canisius College — still recovering from its failure — back to respectability, rejecting more favorable offers. His status of a savior (救世主) brought more pressure than any 18-year-old should have to handle. However, I watched him mature into the player who led Canisius back to daylight.

    After college Hall played professionally in Italy and Greece for over 10 years until a car accident at 32 ended his basketball career. The news that he would never play again shocked Hall but unlike so many others he was ready for life after basketball. When I met Hall — still fit at 46 — for lunch Monday, he wore a cut-sharp gray suit, designer tie and blazing white shirt that screamed Success. “That was always the question — when the cheers end, where do you go? Who do you turn to?” he said. “It starts and ends with that person in the mirror.”

    Hall got the concept of academics-first from his parents. He graduated from Canisius a semester early. “No matter how good of an athlete you are, you are just one injury away from losing it all,” he said. “But if you take care of things academically, you are prepared until you leave this earth.”

    For the past 14 years, he has been in a computer sales job at Ingram Micro. He married his college sweetheart. They have three kids and a nice house in the suburbs. He figured out early what others learn too late: Athletics is part of a journey, not the destination.

    Congratulations, Ray, you made it. In more ways than one.

    The writer Margaret Mitchell is best known for writing Gone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life.

    Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer's life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for the Atlanta Journal newspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men tower over her, but she seems very happy and sure of herself. The tour guide explains: “Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as 'Would you really marry a woman who works?'

    And today it'd be 'Would you marry one who doesn't?' ”

    The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it “The Dump”.

    Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide says Gone with the Wind became a huge success. Margaret Mitchell received the Pulitzer Prize for the book. In 1939 the film version was released. It won ten Academy Awards, including Best Picture.

    One of the most firmly established idea of manliness is that a real man doesn't cry. Although he might shed a tear at a funeral, he is expected to quickly regain control. Sobbing openly is for girls. One study found that women cry significantly more than men do—five times as often, on average, and almost twice as long per period.

    Historically, however, men routinely wept, and no one saw it as shameful. For example, in the Middle Ages, knights cried purely because they missed their girlfriends. In The Knight of the Cart, no less a hero than Lancelot weeps at a brief separation from Guinevere. There's no mention of the men in these stories trying to restrain or hide their tears. They cry in a crowded hall with their heads held high. Nor do their companions make fun of this public crying; it's universally regarded as an admirable expression of feeling.

    So where did all the male tears go? The most obvious possibility is that this shift is the result of changes as we moved from an agricultural society to one that was urban(城市的) and industrial. In the Middle Ages, most people spent their lives among those they had known since birth. If men cried, they did so with people who would sympathize. But from the 18th to 20th centuries, the population became increasingly urbanize, and people were living in the midst of thousands of strangers. Furthermore, changes in the economy required men to work together in factories and offices where emotional expressions and even private conversations were discouraged as time wasting.

    Yet human beings weren't designed to swallow their emotions, and there's reason to believe that holding back tears can be harmful to your well-being. Research from the 1980s has suggested a relationship between stress-related illnesses and inadequate crying. Weeping is also, somewhat related with happiness and wealth. Countries where people cry the most tend to be richer and more confident.

    Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search and rescue dogs help find trapped people. Dogs' amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection(探测) to a whole new level.

    The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds(化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

    The electronic nose can detect extremely slight smell of more than one compound at the same time. "Being able to do this, in such a small object, is the significant discovery," says Sotiris E. Pratsinis, Professor of Process Engineering&Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. "Ideally, this technology could replace search and rescue dogs," Pratsinis says.

    Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, "I foresee that such an object could add to the fine work done by the dogs." Taylor also pointed out some potential limitations of the new invention. "E-noses are useful, but can be very likely to be affected by unstable readings and interruption," he says.
