Skiing has always been a big part of Kamikaze shiffrin's life. Her dad ski raced all through college and her mom raced and coached skiing. The Siffrins taught Mikaela and her brother, Taylor. To ski at a very young age. At two and a half years old, Mikaela made her first ski run down her driveway on plastic skis.

    Mikaela loved skiing. From ages 8 to11, she did hundreds of training runs on small hills to learn the skills of slalom skiing (障碍滑雪). When Mikaela was 11, she began to learn at the Burke Mountain Academy, a Vermont boarding school for skiers. She took classes, studied, and practiced her skiing. According to Burke Mountain Academy headmaster Kirk Dwyer, "What separated Mikaela from others was the degree of her commitment (投入) to be the best. Mikacla practiced more than anyone and believed in herself then and now." At age 14, Mikaela began her international career when she raced in the world championship for13 and 14 -year-olds. And she won!

    By the time she was17, she had already won her first World Cup race. "Living away from home four and five months at a time can be difficult" Mikaela says. "But it can also be exciting. I'm getting to see the world." When Mikaela began ski racing in Europe, her mother, Eileen, stayed with her. She worked as her high school teacher while they were on the road. "She has always been a super-hard worker," says Eileen.

    For Mikaela, working hard is a full-time job. Even her off-season is work time. "If you want something, just try your best," she says. At the 2014 Winter Olympic Games in Sochi, Russia, 18-year-old Mikaela Siffrin became the youngest slalom skier ever to win an Olympic gold medal.

    Pausanias has come on a magical journey (find) out about the present-day Olympic Games. So he asks a Chinese girl, Li Yan about the Olympics. He tells Li Yan Greek cities used to compete against each other the honour of winning. No other countries could join in, nor could slaves or (woman). Li Yan tells Pausanias that every four years athletes from all over the world (admit) as competitors, and all countries can take part if (they) athletes reach the standard to be admitted to the games. Women are not only allowed to join in but play very important role in gymnastics, athletics, etc. At the same time, there is just as much (compete) among countries to host the Olympics as to win Olympic medals. The spirit of the Olympic Games (stay) the same as before: It is all about being able to run faster, jump higher and throw (far).

    Sitting has been called the new smoking for its supposed Public health risks, especially for people with sitting down office jobs. Over the past 15 years or so sitting has been connected with heart disease and diabetes (糖尿病). But is sitting really that risky?

    In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.

    We studied sitting habits of 4. 811 middle-aged people, who didn't have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetes.

    This is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.

    For people who are physically inactive, though, the story's different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obese.

    That's not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.

    For example, sitting down at work isn't strongly connected with long-term health risks, Perhaps that's because higher position jobs needs more sitting, and higher socioeconomic (社会经济) position is connected with a lower risk of disease. It's a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to (a) be of lower socioeconomic positions, unemployed, have poorer mental (精神上的) health, eat unhealthy foods and face more unhealthy food advertising.

    People need to relax and enjoy themselves. One way they can have a good time is to watch a baseball game or another sports event. Even thousands of years ago, groups of people gathered to watch skilled athletes (运动员).

    Over 2000 years ago in Greece, certain days in the year were festival days. These were holidays when people stopped work and enjoyed themselves. They liked to watch athletes take part in races and other games of skill.

The most important festival was held every four years at the town of Olympia. It was held in honor of the Greek god Zeus (宙斯). For five days, athletes from all parts of the Greek world took part in the Olympic Games. At the Olympic Games, people could watch them box, run, jump and so on. There was a relay race between two teams of men in which a lighted torch (火矩) was passed from runner to runner. The Olympic Games were thought to be so important that cities which were at war with one another had to stop fighting. People were allowed to travel to the games safely. Thousands of people came to Olympia from cities in Greece and from her colonies (殖民地) in Africa, Asia and Italy. They met as friends to cheer their favorite athletes and to enjoy themselves.
