    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

    Some time after 10, 000 BC, people made the first real attempt to control the world they lived , through agriculture. Over thousands of years, they began to depend less on could be hunted or gathered from the wild, and more on animals they had raised and crops they had sown.

    Farming produced more food per person hunting and gathering, so people were able to raise more children. And, as more children were born, more food (need). Agriculture gave people their first experience of the power of technology (change) lives.

    By about 6000 BC, people (discover) the best crops to grow and animals to raise. Later, they learned to work with the (season), planting at the right time and, in dry areas, (make)use of annual floods to irrigate(灌溉)their fields.

    This style of farming lasted for quite a long time. Then, with rise of science, changes began. New methods (mean) that fewer people worked in farming. In the last century or so, these changes have accelerated. New power machinery and artificial fertilizers(化肥)have now totally transformed a way of life that started in the Stone Age.

Muhammad Ali was raised in a small home in Louisville, Kentucky. From those humble beginnings neither he nor any observer at that time could have forecast the path he would carve through life. He was a Golden Gloves champion at age 17, an Olympic gold medalist at age 18, and an undefeated heavyweight champion at age 22.

His fighting career began when, spurred by the theft of his prized new bicycle, he was out to get the person responsible. Ali was releasing his anger at the local gym, when the sharp-sighted policeman Joe Martin suggested, "You'd better learn to box first." And he did. And before his career in the ring ended, the world would know his name as the man crowned heavyweight champion three times— the greatest.

Outside of athletics, too, Ali never gave up standing up for what he believed in the 1960s, he took his conviction for draft evasion (拒服兵役) all the way to the Supreme Court, which overturned his conviction in 1971. He used his words as well as his fists, recording two spoken-word album and an R&B song and earning two Grammy nominations (提名奖); writing two autobiographies; and acting in several films and a Broadway musical.

Eventually, his greatest fight was not in the ring. After being the world's toughest human opponents, it was Parkinson's disease that would prove to be his final enemy. In true Ali style, he met this challenge head on. Instead of shrinking from this difficulty, he stepped onto the world stage once more as a champion. His tireless work raising money to fight this terrible disease inspired thousands and endeared him to a new generation of admirers around the world even beyond his death in 2016. As he was in the ring, he remains in our eyes— the greatest.

China' Forbidden City-traditionally off-limit at night for anyone except emperors and visiting dignitaries (显要人物) - was decorated with lanterns as China celebrated the end of the Chinese New Year holiday. The complex, home to Chinese emperors for five centuries, was opened at night for the first time since it was reopened as the Palace Museum 94 years ago.

The complex and palace walls were illuminated with red lanterns and a light show, designed to recreate the feelings of the royal court, while the China National Traditional Orchestra and the Peking Opera performed. An image of a treasured scroll called A Thousand Li of Rivers and Mountains was cast onto the palace roof.

Most of China's 1.3 billion people, however, had to watch the show on television. Only 3,000 people were allowed in: 2,500 invited guests and 500 people who booked their tickets online. "The 3,000 visitors can show off for the whole year," one person said on Weibo. When booking for the second day opened at midnight, the booking system crashed for more than an hour due to great demand. The free tickets were quickly taken when it reopened. A lively secondary market soon appeared. Scalpers were selling tickets for as much as 9,999 yuan on online trading sites.

The Palace Museum is now on a campaign to attract more visitors, with its former curator Shan Jixiang saying he wants to make traditional Chinese culture more accessible to the general public. More than 80 percent of the palace is now accessible to visitors, up from 30 percent in 2012. Shan has set a target of 85 percent by 2020 to mark the palace's 600th anniversary. Creativity today has made the Palace Museum younger and drawn traditional culture closer to the public.

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it.

Cigarette? Cup of coffee? No, it's the third most addictive thing in modern life: the cell phone. And experts say it is becoming more difficult for many people to control their longing to touch it the moment they open their eyes.

 However, I don't mean just the monthly bill. Dr. Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: Besides, it has also become an escape from reality.

Sounds extreme, but we've all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, .

Jim Williams is an industrial sociologist based in Massachusetts. He has done lots of researches on using cell phone. His study shows that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points out in a study that one-quarter of Americans say they have no one to discuss their most important personal business with.  " Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends." he says,

A. And most of them don't have many friends.

B. When you get into a lift, you play with it.

C. Cell phones are becoming more and more useful.

D. The costs are becoming more and more evident.

E. avoiding contact with kids all around him

F. It has become a barrier to one-on-one personal contact.

G. paying attention to the real world
