Shelly-Ann Fraser-Pryce, born on December 27, 1986, is a Jamaican track and field sprinter who competes in the 60 metres, 100 metres and 200 metres.

Not so long ago, most people didn't know who Shelly-Ann was going to become. She was just an average high school athlete. There was every indication that she was just another teenager without much of a future. However, one person wanted to change this. Stephen Francis observed then eighteen-year-old Shelly-Ann at a track meet and was convinced that he had seen the beginning of greatness. He decided to train Shelly-Ann strictly. Their cooperation quickly produced results. At the 2008 Beijing Olympic Games, Shelly-Ann beat Jamaica's unchallenged queen of the sprint. Widely regarded as one of the greatest sprinters of all time, her achievements on the track since 2008 helped to elevate Jamaican athletics on the international scene.

Shelly-Ann is a little woman with a big smile. She has the mental toughness that did not come about by chance. Her journey to becoming the fastest woman on earth has been anything but smooth and effortless. She grew up in one of Jamaica's toughest communities known as Waterhouse, where she lived in a one-room apartment, sleeping four in a bed with her mother and two brothers. Waterhouse, one of the poorest communities in Jamaica, is a really violent and overpopulated place. Sometimes her family didn't have enough to eat. Her mother Maxime, one of a family of fourteen, had been an athlete herself as a young girl but had to stop after she had her first baby. Maxime's early entry into the adult world gave her the determination to ensure that her kids would get rid of poverty. Therefore, one of the first things Maxime used to do with Shelly-Ann was taking her to the track and she was ready to sacrifice everything.

When talking about her achievements and legacy, this incredible woman responded that her secret is just staying humble, just knowing who you are as a person and as an athlete and just continuing to work hard. “I don't pay much attention to where I fall in history. When I decide to leave the sport, I want to leave it better than I saw it. I want to make sure that other young athletes can see that you need to work hard, you need to stay humble, you need to stay focused, and the sky is the limit,” Shelly-Ann said.

World's loneliest marathon

Many of us know about Russia's Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian's hit song, Lake Baikal. But over the past decade, the world's deepest freshwater lake has been in the spotlight for an extreme sport.

Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake's breathtaking beauty and challenge themselves in unpredictable conditions.

The 26-mile (41. 84-kilometer) journey starts on the lake's eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.

Known as the "blue eye of Siberia"，Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. "Seen from above, a runner on the ice looks as if he or she were jogging through space," The New York Times noted.

The landscape might be beautiful, but it's also harsh. Strong winds blast across the lake and frostbite(冻伤) can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.

"When you are in such an environment, you don't have cars around you, and you don't have the noise around. I think these extreme races allow you to be alone with nature," Alicja Barahona, a 64-year-old runner from the US, told ABC News.

The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start, but the endless white offers no progress markers. The race also ends with little fanfare(喧闹)。Tourists crowding the ice are mostly addicted to snapping themselves and just ignore the runners.

For some runners, the absence of spectators(观众)makes the race more challenging, because it's lonely. They must fight with themselves. "You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is defeat yourself," Veronique Messina, a French runner, told The Telegraph.

It can be easy to miss the wonderful performances of Klay Thompson if you watch the games of the Golden State Warriors(金州勇士)in the NBA.

NBA Most Valuable Players Stephen Curry and Kevin Durant tend (get) most of the attention, while Andre Iguodala (watch) closely as well. But then Thompson, 26, does something to make you suddenly remember how special he is, too.

His 60-point game against Indiana on Dec. 5 was an excellent game in has already been an amazing season. Scoring 60 (point) in a game is one thing, and it has only happened 66 times in the history of the NBA. But to do it in less than three quarters of play—29 minutes— (be) something special indeed.

Even  (hard) to believe was the fact that Thompson only dribbled(运球)the ball 11 times and held it in his hand for just 88 seconds during  whole game.

"I am going to watch the tape of this game and see what I did and (obvious) celebrate this tonight, because it's something I never thought I could do while (grow) up," Thompson told reporters after the game.

Klay Thompson already knew a lot about basketball early in his life. His father Mychal Thompson, the 1978 No. 1 overall pick(选秀状元)in NBA, had a lot of influence  him.
