In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I'd hitch a ride (搭便车).

    I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn't give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured （使…放心）me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.

Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favour I'd been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.

    After a few moments of small talk, the man said to me, “You haven't changed a bit, even your red hair is still the same.”

    I couldn't remember where I'd met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.

    What would it be like to walk on Mars? If you could build the highest building in the world，what would it look like? Do you dream of being the next J. K. Rowling? This summer, you can experience all of these things, and more. All you need is an Internet connection and your imagination.

    A recent study by the Kaiser Family Foundation found that kids spend an average of 1 hour and 29 minutes online each day. Many kids like to use that time to chat with friends, play games or check e­mails. But the next time you get on the Web, try exploring the world instead. “With the Internet，you can go back 11,000 years in time，or go 11,000 kilometers across the planet.” said Russell, Web search expert of Google. “The whole scope of history and the world is open to you.”

    There is a wealth of information to be found online. For example, if your family is going on vacation somewhere, do a quick online search on the area before you even get in the car. “What's the background of the place; what's the history？” says Russell. “I like to tell my kids, ‘Whenever you have a question, whenever you have a doubt, search it out.'”

    Ready to launch a virtual journey of your own? Here are a few starting points to get you thinking and to help you on your way. You can invite your parents along for the ride, too. Always ask for permission before downloading programs and software onto your computer. And check with a parent or an adult before visiting any new Web site.

    Navigate the world in 3­D with Google Earth. Begin in outer space and zoom (快速移动) into the streets of any city, from Hong Kong to San Francisco. Or visit ancient monuments, watch the changing rainforests over time, and dive underwater to explore tropical reef.

    With the Moon in Google Earth tool, you can walk in Neil Armstrong's famous footsteps. Take a guided tour of the moon's surface with Armstrong's fellow shuttle mate astronaut Buzz Aldrin.

    When you're exploring that part of the solar system, hop on over to the Red Planet with Google Mars. There, you can move very quickly around the surface and see images from the Mars Rovers.

    The softshell turtle species is officially listed as endangered by the IUCN Red List. Scientists long thought softshell turtles were extinct in the Cambodian part of the Mekong River until they discovered some stragglers (掉队者) in the early 2000s.

    The species had quite a wide historical range across Asia, but much of that range is now completely gone. Much of the turtle's habitat in Southeast Asia have disappeared due to urban and industrial development along the Mekong River. The sand where turtles multiply is routinely carried away for use in construction projects, while fishing nets lift up hatchlings. People also take turtles and their eggs to sell for food.

    Initial surveys in 2003 and in 2007 found two small populations of the softshell turtles along a 30-mile stretch (水域) of the Mekong River. Since then, conservation groups have worked with local communities and officials to increase the wild population of these endangered turtles, including a program to hire former egg collectors to help search for and protect nests instead of harvesting the eggs.

    For the last decade, WCS, Conservation International, the Turtle Survival Alliance and local groups have worked to protect turtle nests. Their goal is to ensure eggs will multiply and hatch, and that baby turtles grow strong enough to eventually take care of themselves in the wild.

    A team recently released 150 hatchlings back into their natural habitat, bringing the total to more than 7,700 baby turtles in the past 10 years.

    Partway through Wonder, Fifth-grader Auggie Pullman finds himself seated across from a new friend in the school cafeteria. "Have you ever thought about having plastic surgery?" the friend asks.

    "Dude, this is after plastic surgery. It takes a lot of work to look this good," Auggie says, running a hand through his hair. In other words, what could be painfully depressing turns out to hold lurking (潜藏的) reserves of humour, which is pretty much the story of Wonder.

    Auggie, played by Jacob Tremblay, was born with a facial difference, and even after multiple operations, his looks shock his classmates. As he adapts from homeschooling to a new school community, he encounters far worse than that lunchtime scene—one nasty bully (横行霸道者) says he'd kill himself if he looked like Auggie—but he never fully loses heart.

    The movie is an adaptation of the 2012 novel by R.J.Palacio, which has sold 6 million copies in North America and launched an antibullying campaign, Choose Kind. Palacio has said she got the idea for the story when her young son began crying at the sight of a girl with a facial difference in an ice cream shop. She took her kids out of the shop, but later regretted her reaction. "What I should have done is simply turned to the little girl and started up a conversation and shown my kids that there was nothing to be afraid of," she said.

    Tremblay, 11, who broke out opposite Brie Larson in the 2015 drama Room, has more than a few things in common with Auggie. "We both love Star Wars, we have awesome families, and we love our dogs." But Tremblay thinks we all can find something in common with the boy. "Everyone's like Auggie in one very important way: we want to be accepted and treated equally and with kindness."

    Julia Roberts, who plays Auggie's mother, became interested in the part because of her own children, "I read it with my kids and fell so in love with it," she says of the novel. "This book is such a beautiful and gentle introduction into all kinds of topics, including bullying and intolerance and fear, and what fear makes young people do sometimes."

    Both actors have some familiarity with the subject. "I was picked on quite a bit as a young person," Roberts says, though she won't say what for. "Even as a 50-year-old mother of three, it's not a path I like to go up and down." Tremblay reveals a bit more. "I have been picked on," he says, "because I'm kind of short for me age. I told my parents, and that's one of the best things you can do, because my mom said would never want me to carry negative thoughts on my shoulders alone."

    The most challenging parts of filming, says Tremblay, were moments in which he had to cry. Tenderhearted audience members will likely shed tears of their own—especially during scenes between Auggie and his mom, who repeatedly reassures her son that he is worthy of love. But the movie also has its fair share of hijinks (喧闹): for every tear-filled moment, there is a lightsaber battle or silly science project to lighten the mood. This mixture of pity and humor, says Roberts, "was intrinsic (固有的) in the writing in the novel." But she credits writer-director Stephen Chbosky with translating that balance into visual terms.

    As much as the movie impresses the viewer with compassion for the underdogs, it also finds a way to sympathize with the bullies. "I would say to try to take a moment to be conscious of why a person that is bullying somebody is behaving that way," says Roberts, "After all", she adds, "There's no child that's born bully."

After months of expectation and secrecy, the official mascot (吉祥物) of the 2022 Winter Olympic Games－a giant panda-inspired cartoon character－made its first public debut with cheers at Beijing's Shougang Ice Hockey Arena.

The panda is named “Bing Dwen Dwen” in Chinese. Bing means “ice” in Chinese, while Dwen Dwen suggests “health and cleverness”－characteristics also shared by pandas. Pandas are perhaps the most recognized animal species in China, organizers said.

“Pandas combine China's traditional culture and its modern appearance together with winter sports elements in a fascinating image (形象) that shows our great expectations for the Games and shows that we welcome the world,” said Beijing Mayor Chen Jining, who also serves as an executive president on the organizing committee.

“I have already seen the mascot and from what I've seen, it's a wonderful choice,” IOC President Thomas Bach said before introducing the character.” “The mascot really takes in the best elements and characteristics of China and the Chinese people. It will be a great ambassador (大使) for the country and the 24th Winter Olympics.”

The ring of light surrounding the mascot's face is suggestive of ice and snow tracks, as well as the flowing “ribbons” of the National Speed Skating Oval. The oval is one of two new competition sites in downtown Beijing expected to become a landmark of the Games, according to its chief designer Cao Xue.

The introduction of the mascots marks the key point of a journey that began in August 2018, when Beijing organizers started a global design competition for the mascots. A total of 5,816 designs were received from 35 countries, and were reviewed by Chinese and international experts in a comprehensive evaluation and selection process.

The new mascot will serve as spirited symbol of the Games that will take place in the three zones of downtown Beijing, the suburban district of Yanqing and co-host city Zhangjiakou in surrounding Hebei province.

Colorado's grays peak rises 14,278 feet above sea level, high enough that trees can't grow toward the top, though there are plenty of shrubs and rocks. It was in this unforgiving landform that Bev Wedelstedt was unlucky enough to get seriously injured in her left knee.

It was August 2018, and Wedelstedt, 56, was on her way back down the trail with three friends. A storm was brewing, and they were anxious to get off the mountain. When they approached a rocky drop of a couple of feet, Wedelstedt decided to leap. She landed on her left leg. Then she heard the snap. Every step after that was agony（剧痛）. Before long, she had to stop. As one friend ran down to get help, a number of other hikers, all strangers, attempted to help Wedelstedt down the narrow trail by walking on either side of her to support her weight, but that proved slow and dangerous. "One man was so close to the edge that I could see rocks falling down from where he stepped on them." Wedelstedt says.

Finally, one hiker, Matt, asked her, "How do you feel about a fireman's carry?" Before she knew it, he had lifted her over his shoulder. "Now, I'm not tiny," says Wedelstedt, a former college basketball star. Matt clearly couldn't carry her all the way down by himself. So six hikers and one of her friends took turns carrying her while she tried to make light of a difficult situation: "I told them I wanted to meet a lot of guys, but this isn't the way I wanted to do it." Three hours and two rock-strewn miles later, this human conveyor belt finally met the medics, who took Wedelstedt to the hospital.

She stayed in hospital for a period time. Now she has mostly recovered from her ill-fated hike, but Wedelstedt knows she'll never shake one thing from that day: the memory of the band of strangers who came to her rescue. "I'm still in awe."
