There are two ways of driving in the world: if the driver's seat is on the left and cars travel on the right side of the road, it is called “left-hand driving”, as it is in China, while the other way of driving is called “right-hand driving”, as it is in Britain. Nowadays, around 65% of the world's population drives on the right of the road, while the rest is used to driving on the left.

    Though no one knows the exact reasons, it seems likely that people in ancient times travelled on the left. Roman coins show pictures of horsemen passing on each other's right. And right-hand people generally got on a horse from the animal's left. Obviously, it's safer to do this at the left side of the road, and it makes sense for the horse to be ridden on the left.

    A change happened in the late 1700s. When Napoleon conquered nations, he forced them to travel on the right side of the road, which spread left-hand driving throughout Europe. However, Britain still stuck with the right-hand driving rule and countries which were part of the British Empire (帝国) were made to follow. This is why India, Australia and the former British colonies (殖民地) in Africa continue to drive on the left. One exception is Egypt, as that country was defeated by Napoleon before becoming part of the British Empire.

    Some countries changed sides' until modem times. Sweden only moved to driving on the right in 1967 and Iceland changed the following year. Ghana changed sides in 1974. On September 7,2009, Samoa became the third country ever to change from left-to-right-hand driving for the reason that it made it easier to import (进口) cheap cars from right-hand driving Japan, Australia and New Zealand.

    So if you want to travel to another country or go on business, make sure you know whether it is left-or right- hand driving to avoid unnecessary troubles.

    Fat and shy, Ben Saunders was the last kid in his class picked for any sports team. “Foothall, tennis, cricket-anything with a round ball, I was useless,” he says now with a laugh. But back then he was the one always made fun of in school gym classes in Devonshire, England.

    It was a mountain bike he received for his 15th birthday that changed him. At first he went biking alone in a nearby forest. Then he began to-ride the bike along with a runner friend. Gradually, Saunders set up his mind on building up his body, increasing his speed and strength. At the age of 18, he ran his first marathon.

    The following year he met John Ridgway and was hired as an instructor at Ridgway's school of adventure in Scotland, where he learnt about Ridgway's cold-water exploits. Greatly interested, Saunders read all he could about North Pole explorers and adventures, then decided that this would be his future.

    In 2001, after becoming a skillful skier, Saunders started his first long-distance expedition towards the North Pole. It took unbelievable energy. He suffered frostbite, ran into a polar bear and pushed his body to the limit, pulling his supply-loaded sled（雪橇）up and over rocky ice.

    Saunders has since become the youngest person to ski alone to the North Pole, and he's skied more of the North Pole by himself than any other British man. His old playmates would not believe the change.

    Next October, Saunder, 27, heads south from the coast of Antarctica to the South Pole and back, a 2900-kilometer journey that has never been completed on skis.

    A 1ot of teens aren't responsible, and that's where I'm different. Not just about school but everyday things, like being able to pay my own credit card(信用卡)bills on time.

    The first time I got a cartoon book was on my third birthday. From then on, I fell in deep love with it. And can you guess how many cartoon books I've read? I don't really know the exact number. But I have three full boxes of them under my bed.

    I'm proud of doing things in my own way. So whenever somebody wants me to do something or whatever it is, I feel like they're all other people's thoughts, not really mine. But like others, I love reading, too.

    When I first took skiing lessons, I found it exciting. For skiing racing, there's no question that I'm better than most boys. I think it's fun. I mean, it is a challenge. It's where I picked up the idea of needing a challenge always in my life. In order to improve my skiing skills, I have read many books and magazines about it.

    An Qi 15 years old China

    I'm different because I prefer to drop out of the world to create my own world. I'd like to build a house on a mountain. And I choose to live without electricity, a telephone, or even indoor plumbing(水管装置).

    I have many hobbies such as traveling, reading, writing and spending time with children. I love children because they are smart and creative. They always have many strange ideas. It makes me excited.

    I want to do something for Hope Project and become a country school teacher.

    Forty-three years ago, a man took a "small step" on the moon and brought mankind a "giant leap" forward. As the first person to walk on the moon, American astronaut Neil Armstrong is a man whose name will be remembered for generations to come.

    But being the first is never easy. With so many unknowns about space at that time, Armstrong himself was astonished that Apollo 11 actually worked. He thought he and his partners had merely a 50 percent chance of a successful landing back in 1969.

    It was tough indeed. When the module (登月舱) was approaching the moon's surface, the computer wanted to rest them on a steep slope covered with rocks, but Armstrong realized it was an unsafe place to stop.

    As a last minute decision, he safely landed the module by himself. When they finally touched the ground, "there was something like 20 seconds of fuel left," he said in an interview earlier this year.

    Unfortunately, some people doubted his visit to the moon, saying it was faked. But Armstrong responded with a chuckle (轻声笑), saying: "It was never a concern to me because I knew one day, somebody was going to go fly back up there and pick up that camera I left."

    For all his global fame, Neil Armstrong is a remarkably modest man. He rarely gave interviews and didn't like talking about his achievement. He stopped giving his signatures when he found that people sold them for thousands of dollars.

    "I guess we all like to be recognized not for one piece of fireworks but for the ledger (记账簿) of our daily work," Armstrong said in a CBS interview in 2005. When asked how he felt knowing his footprints would be likely to stay on the moon's surface for thousands of years, he said: "I kind of hope that somebody goes up there one of these days and cleans them up."

    Armstrong passed away last month at the age of 82, but he will be memorized. "The next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink (眨眼示意)," his family said to Reuters.

    E-Sports, short for electronic sports, is one of the growing industries in the world, with prizes totaling around $25 million up for grabs in some tournaments. E-Sports are professional multiplayer video game competitions. Any video game with a strong competitive element is considered e-Sports. The competition models itself after traditional professional sports in several ways: it uses corresponding tournament formats, involves player contracts, and is governed by regulations. The athletes who compete in e-Sports competitions are gamers．

    The history of e-Sports dates back to 1972 when some Stanford University students competed in the Intergalactic Space War Olympics for the opportunity to win a one-year subscription to the Rolling Stone Magazine. E-Sports pretty much continued on the rather quiet path until the 80s when competitions like the Space Invaders Championship shot them to the spotlight. 2002 marked the beginning of a new era for the sport and laid the foundation for what e-Sports would become thanks to the release of the Xbox live, which brought online play to consoles. Halo Ⅱ became the first game to be shown on national television for Major League Gaming in 2004, paving the way for e-Sports to become a global phenomenon.

    Today, e-Sports are growing at a rapid pace thanks to advance in technology and the arrival of streaming services like Twitch which have exposed video game competitions to a new audience due to their extensive reach.

    To understand how much impact Twitch has made, data from gaming analyst group Newzoo show that e-Sports global audience increased 43 percent from 204 million to 292 million between 2014 and 2016. Interestingly, this coincides (一致) with Amazon's acquisition of Twitch in 2014 and its effort to make the competition a spectator sport.

    There are always stories in the life that can hardly be forgotten and will restore our hope for holidays every time we recollect.

    Johnny and I, along with our two young sons, Barry and Doyle, lived in a village in southern Alabama in 1979. We had bought the boys a bicycle for the New Year, and had hidden it in the garage ,where Johnny would assemble (组装)it on New Year⁵ s Eve after the kids fell asleep. But that day, Johnny had to go to Brookley Air Force Base in Mobile, an hour away, to repair a jet. I had my hands busy with baking, preparing for holiday dinner and caring for two energetic boys.

    Just as I was making the chocolate cake, a neighbor knocked on the door. It was Beatrice, who was the only person on our road with a telephone. The base had called to say that a heavy tool had come apart suddenly, hitting Johnny's arm and breaking the bone. My brother Otto took me to the base hospital while my mother stayed with the children.

    We got there to find Johnny with a cast (石膏)on his arm, anxious to get home regardless of the doctor's orders. It was New Year's Eve, Johnny argued, and he had the bike to assemble for his boys. The doctor said he'd consider dismissing him the next morning if Johnny could find someone to drive him home. On New Year's morning, Johnny called the base and was told everyone was off duty; there was no one to drive him home. Johnny kept making calls. At last, a big blue car with the Air Force sign rolled up.

    I was putting dinner on the table when hearing the car. We were thrilled to see Johnny assisted by a uniformed Air Force officer. With Otto's help, Johnny assembled the boy's gift, and they all had a good time that afternoon. Our hearts were full of gratitude to the people who had gone the extra mile to bring us together.
