Rosie Dutton, a teacher from Relax Kids in Tamworth, UK, used two apples to show her students the often unseen but harmful effects of school bullying(校园欺凌). She posted the lesson on Facebook, where it's been shared more than 160,000 times.

    Rosie Dutton explained that during one of her classes she presented the children with two red apples. What the kids didn't know was that before the lesson, she had repeatedly dropped one of the apples on the floor. And yet, on the outside at least, both apples looked perfect.

    “I picked up the apple I'd dropped on the floor and started to tell the children how I disliked this apple,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either, so they should call it names too.”Some of the children looked at her as if she were “crazy”, but the students passed the apple around the circle, calling it names.

    Continuing the exercise, the teacher then passed the second apple around the circle. This apple, however, was showered with words like: “Your skin is beautiful,” and “ what a beautiful colour you have.”

    Dutton then showed the students both apples once again, stressing that “there was no change, and both apples still looked the same.”

    Finally, Dutton cut both apples open. The apple that the class treated kindly looked fresh inside. But the other apple—the one they'd treated poorly —was bruised（瘀伤的) beneath its skin.

    “I think there was a light bulb moment for the children immediately,” Dutton said. “When people are bullied, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling. If we hadn't have cut that apple open, we would never have known how much pain we had caused it.”

    Dutton explained how important it is to teach children to stand up for one another, and to stop any form of bullying.

    “Let's create a generation of kind caring children,” the teacher wrote. “The tongue has no bones, but is strong enough to break a heart. So be careful with your words.”

    Gardening can be a very relaxing hobby for many people and this wonderful experience is not just for adults. Children are interested in gardening as well, if given the chance to explore nature and science in this way. Gardening can bring joy to both children and their parents alike, especially when the experience is shared together.

    The time that is spent gardening together builds precious memories within their hearts and minds for years to come. When you are gardening with your children, try to give them their own special area. Keep their area in the center of the best soil and light, as you want to make sure of a successful gardening experience.

    Plastic tools easily break and are difficult to use in the dirt, so when you are gardening with your children, give them real tools to use if possible. Even offering to let them use your tools is a way to admit the worth of the work they are doing. It is also important to talk with your children about the whole process of gardening, from planting to the harvest. They need to understand how things work and the importance of what they are doing.

    Show off the children's gardening work by taking friends and visitors for a walking tour through the garden and point out the children's particular spot. When you give attention to the children's work, this is a great motivation（动机） for children to continue wanting to be involved. Do not force children to take part when they are in a bad mood or if they are becoming bored. Instead, allow them to do something different, like building a scarecrow(稻草人)! This makes the gardening experience even more interesting. As you work together side by side with your children, you will encourage a love of the land in them, as well as creating lasting memories of time spent with you.

    A year ago, I paid no attention to English idioms, though my teacher emphasized (强调) the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.

    One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished. Gently shaking his head, shrugging his shoulders, he said, “You don't say!” “You don't say!” I was puzzled. I thought, perhaps this is not an appropriate topic (适当的话题). “Well, I'd better change the topic.” So I said to him. “Well, shall we talk about the Great Wall？ By the way, have you ever been there？” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was magnificent.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it..” Soon I was interrupted again by his words: “You don't say!” I couldn't help asking, "Why do you ask me not to talk about it？" "Well, I didn't request you to do so, " he answered, greatly surprised. I said, "Didn't you say' you don't say？”Hearing this, the Englishman laughed to tears. He began to explain, “'You don't say' actually means 'really!' It is an expression of surprise. Perhaps you don't pay attention to English idioms.” Only then did I know I had made a fool of myself. Since then I have been more careful with idiomatic expressions. Remember: what the English teachers said is always right to us students.

    It's been a hard time for rhinos (犀牛) lately. Recently the International Union for Conservation announced the western black rhinos had died out in the wild. It was last seen in western Africa in 2006. Now, those who work to protect the animals are trying to make sure that won't happen to other rhinos.

    19 south-central black rhinos in South Africa were driven to an area nearly 1,000 miles away, which was said to be the gentlest and quickest way to transport the animals. They were taken to a new home that would keep them safe from hunters.

    Though it is not allowed to hunt rhinos, many are still killed for their horns, which can sell for as much as $ 30,000 each. Most of them are used to make drugs as traditional medicines in Asian countries. Some people believe that the horns work well in treating pain, fever and even cancer. However, there is no medical evidence yet.

    Black rhino population began falling rapidly in the second half of the 1900s because of poaching. In fact, some people still hunt the animals at the risk of being put into prison. And many of the places where the animals used to live in were destroyed when people started building farms on the grasslands. Until the 1960s, about 65,000 black rhinos lived throughout most of Africa. Today, fewer than 5,000 are left—most of them in zoos and wildlife reserves.

    South Africa has the largest population of rhinos in the world. Poaching is an especially big problem in that country. So far, more than 340 rhinos have been killed there. Since 2003, the Black Rhino Expansion Project has been helping the south-central black rhinos in South Africa. The group works with landowners to find areas where rhinos can live safely away from hunters.

    So far, the group has successfully saved about 120 rhinos. Leaders of the project say the south-central black rhinos have seen a rise in numbers. It is hoped that, with continued support, these rhinos can escape the unfortunate result of the western black rhinos.

    After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete's ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.

    Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, "extra blood" was never something WADA tested for.

    But WADA wasn't going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport's partial implementation (实施)—recording blood and steroid levels—began in January 2014.

    When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete's normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.

    WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete's feature in the biological passport.

Discovering a hobby can lead to amazing results, as Maria Martinez, an 11-year-old with a heart of gold, has proven.

Just over a year ago, Maria came across the world of clothes-making, thanks to one of the Christmas gifts she received. Little did she know that this newfound ability would become a source of joy and purpose, not just for her, but also for countless furry friends.

"I got a gift permitChristmas to start clothes-making lessons," Maria said. "I really liked it."

After mastering the basics, an idea came to her mind during a visit to a local exhibition. Surrounded by pet owners and their pets, Maria had an idea that would change lives. Why not create lovely bandannas (头巾) for dogs and cats and use them to support animal shelters?

With great interest and the support of her grandmother, Maria turned a corner of their home into a busy working room. Together, they made many beautiful bandannas, each one filled with love and care.

But Maria's wish went far beyond creating decorations. She began donating her works to shelters like Claws Forever in Fall River, hoping to catch the eye of some people who can take these dogs and cats home.

Maria also began selling them through word-of-mouth and at various events. "At first she started just donating the bandannas because it took her much time to make them. Then she got more skilled and was able to buy cloth with some extra income that she was making from it," her mom, Crystal, said. "Maria is a really kind giving person and she doesn't want for much of anything. It makes her feel good to donate. We are proud of her." Ranging from $3 to $7, money from her sales is now donated to shelters, too. A few weeks ago, she donated more than $200 to the Kingston Animal Shelter.

"They were happy and really grateful, which made me feel really good inside," said Maria. "It makes me happy to see how it's impacted the people and dogs."
