    When Allison Winn was eight and her family adopted a dog named Coco, they had no idea how much the little creature would change her life. “Coco helped me feel better,” says Allison, who was recovering from l4 months of treatment for a brain cancer at the time. “She would cuddle（偎依) with me when I didn't want to play.” Allison loved Coco so much that she told her parents she wanted to help other sick kids find the same kind of comfort.

    She started small, raising money by selling lemonade and home-made dog biscuits in front of her house. Her first customer was the mailman. By the end of that summer, she had raised nearly $l,000, enough to adopt and train two dogs and give them to children with cancer. Now, a little more than two years later, some groups gather to make dog treats for Allison's cause.

    Her organization, the Stink Bug Project, named after a picture she drew in memory of the end of her treatment, is run and managed in partnership with the Morgan Adams Foundation. Stink Bug helps families adopt pets from the Trained K9 Companion Program, where the rescued dogs are taught commands. Allison's mother, Dianna Litvak, who helps run Stink Bug, hopes to extend the pet-adoption program statewide and continue donating some of the money to help fund children's cancer research.

    “Allison has figured out how to help - in a way that no one else has,” Litvak says. “We involve her younger sister, Emily, her friends, the adopting families, and some others. It took the love of a little girl to wrap all that together into one amazing package.”

    Helen Thayer, one of the greatest explorers of the 20th century, loves challenges. She says, “I like to see what's on the other side of the hill.” She has gone almost everywhere to do that.

    In 1988, at the age of 50, she became the first woman to travel alone to the North Pole. She pulled her own sled (雪橇) piled with 160 pounds of supplies, and during her trip no one brought her fresh supplies. Accompanied (陪伴) only by her dog Charlie, she survived cold weather and meetings with polar bears. In fact, Charlie saved her life when one of them attacked her. Near the end of her trip, a forceful wind blew away the majority of her supplies. The last week of the trip, she survived on a handful of nuts and a little water each day.

    Helen goes to challenging places not only for adventure, but also for education. Before her Arctic journey, she started a website called Adventure Classroom. On the site, she shares her adventures in order to motivate (激发) students. She explains, “Although kids often see the world in a negative way, without hope for their future, we work to inspire them to set goals, plan for success and never give up…” Helen grew up in New Zealand. Her parents were athletes and mountain climbers. Following how parents' example, she climbed her first mountain at 9. Later, she climbed the highest mountains in North and South America, the former USSR and New Zealand.

    In 1996, she took on another challenge-the Sahara Desert. She and her husband, Bill, walked 2,400 miles across it! In 2001, she and Bill traveled on foot from west to east through the Gobi Desert in Mongolia. They hope to travel in mainland China into Sichuan and Tibet to study pandas this year.

    Helen plans to continue taking trips. She'll use her colorations, writing, photography and environmental work to create programs for her Adventure Classroom website. She wants to inspire her students never to stop facing challenges!

    Although his 1-year-old smart-phone still works perfectly, Li Jijia already feels the need to replace it.

    “There are many better ones available now. It's time to upgrade(更新）my phone.”

    Li's impatience is shared by many. Shortly after the season when new products are released（发布，发售）, many consumers feel the urge to upgrade their electronic equipment, even though the ones they have still work just fine.

    As consumers' minds are occupied by Apple's newly released products and debate whether the Google tablet is better than the new Amazon Kindle, it might be time to take a step back and ask: “Do we really need the latest upgrades?”

    According to Donald Norman, an American author, “planned obsolescence (淘汰）” is the trick behind the upgrading culture of today's consumer electronics industry.

    Electronics producers strategically release new upgrades periodically, both for hardware and software, so that customers on every level feel the need to buy the newest version.

“This is an old-time trick—they're not inventing anything new,” Norman said. “This is a wasteful system through which companies--many of them producing personal electronics-- release poor-quality products simply because they know that, in six months or a year, they'll put out a new one.”

    But the new psychology of consumers is part of this system, as Norman admitted, “We now want something new, something pretty, the next shiny thing.” In its most recent year, Apple's profit margin(利润) was more than 21 percent. At Hewlett-Packard, the world's biggest PC maker, it was only 7 percent.

    Apple's annual upgrades of its products create sales of millions of units as owners of one year's MacBook or iPhone line up to buy the newest version, even when the changes are slight.

    As to Li Jijia, the need for upgrading his smart-phone comes mainly from friends and classmates. When they are switching to the latest equipment, he worries about feeling left out.

    “Some games require better hardware to run,” said Li. “If you don't join in, you lose part of the connection to your friends.”

    On the day the tornado hit, there was no indication severe weather was on its way—the sky was blue and the sun had been out. The first alert my husband, Jimmy, 67, and I, 65, got came around 9 p.m., from some scrolling text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the presidential primary debate I had been watching to our local Pensacola, Florida, station.

    No sooner had we found coverage of the tornado than it was on top of us. Suddenly, the bones of the house shook, the power went out, and the wind began to roar through blown-out windows. We had three flights of steps to navigate to the relative safety of the first floor, where a closet fixed underneath a brick staircase might be the firmest place to wait things out. Everything around rattling, we struggled forward, uncertain whether we would make it.

    As we reached the last flight of steps, our front door blew out. Shards of glass flew everywhere. A three-foot-long tree branch whipped, missing us by inches.

    By the time I reached the closet, the tornado had been over us for about a minute. Jimmy pushed me down to the closet floor, but the wind kept him outside. I grasped his arm as the tornado constantly sucked the door open and tried to bring him with it. My knees and scalp were full of glass, but I felt no pain. If I had let go, Jimmy would have flown right out the back of the house and into the bay. Then everything stopped. In those first quiet moments, I couldn't believe it was over.

    The storm lasted four minutes. Four of the twelve town houses in our unit were completely destroyed. Of the houses left standing, ours suffered the most damage. Amazingly, none of us were severely injured.

    Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a house for me and our children.

    During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

    He reported the case to the police and then sat there, lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

    Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband's name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can(垃圾桶)that had been left out on the footpath.

    My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

    That family not only restored the important documents to us that day but also restored our faith and trust in people. We still remember their kindness and often send a warm wish their way.

Kelli Boehle says her son Nik was an amazing and caring person. Nik was diagnosed (诊断) with cancer in 2008 when he was 17. He passed away in 2012. But Nik's kindness and generosity have lived on long after his death

After he was diagnosed and started treatment, Nik was granted a wish experience from the Make-A-Wish Foundation. "For just this period of time, we didn't think about cancer," Kelli Boehle said. "All we thought about was enjoying our time together." In 2009, Nik met another young man Nate, who was also going through cancer treatment. He'd been diagnosed a month after turning 18, and Nik learned he was too old to qualify for a wish. The night before Nik passed away, he asked his mother to help ensure that young adults fighting cancer could have their wishes come true too.

"It was like a seed he planted that just wouldn't stop coming into my mind," she said. In 2012, Kelli Boehle started Nik's Wish. The nonprofit grants wishes to young adults between the ages of 18 and 24 who are battling cancer. Nate was the organization's first wish recipient. "It's meant to bring them joy and know that they're loved and that we're fighting for them, too," Kelli Boehle said.

Recently, 19-year-old Jordan Morrow received her wish to attend a Taylor Swift concert as part of a trip to Los Angeles. For Morrow, who has spent the last year battling brain cancer, going to the concert has done more than lift her spirits. "I think it's something to get me through whatever comes my way," she said. "And I'm thankful for Nik's Wish for that."

In the 1lyearssinceNik passed away, the organization has granted more than 300wishes across more than 30 states. In the beginning, Kelli Boehle says she wasn't sure she could be a wish maker and work closely with the young adults.But now, it'sher favoritething to do.
