Eight-year-old Owen Howkins suffers from growth delays(迟缓) and poor eyesight. This means that Owen needs a wheelchair to get around. Not surprisingly, he felt people were staring (盯着看) at him, and that made him very uncomfortable, so he became lonely and even stopped going outside of his house. That, however, was all before Haatchi came into his life!

    Haatchi had a very unlucky start to life too. Tied to a railway track when he was just five months old, the dog was hit by a train. The hit unjured his tail and a leg so badly that both had to be cut off. Taken to a rescue shelter(救助站), the dog would have probably been killed if his story posted on Facebook had not been seen by Owen's dad Will. He fell in love with Haatchi and decided to keep him, thinking that they were helping him. It turns out that it was Haatchi who helped them. By always staying at young Owen's side, he became the boy's best friend. Slowly Owen liked to go outside. Wherever he goes, the dog follows and protects him. Owen now proudly walks around the neighborhood, showing off his dog and telling anyone willing to listen, Haatchi's story.

    Haatch's positive influence on the young boy has not gone unnoticed. In October 2012, the International Fund of Animal Welfare presented him with a special award(奖). The amazing friendship between the two has also been shown in a touching short film called “A Boy and His Dog” by students from the filmmaking class at the University of Hertfordshire. It has won several awards and had almost 2 million views. British best-selling author Wendy Holden has also writtern about this touching friendship in a aheartwarming children's book, which was released on February 13th and had made Owen and Haatchi better known!

    Dolphins (海豚) live in a dark underwater world. It's often impossible to see each other or anything else around them, so sound plays an important role in their survival. To communicate with each other, dolphins produce all kinds of sounds.

    Only other dolphins understand what the sounds mean. Scientists haven't uncovered their secret communication, except for one kind of whistle. It might last less than a second, but this whistle is a big deal. Why? Because these whistles are actually names of dolphins — and every dolphin has one. Scientists call these sounds a “signature whistle.” When other dolphins hear the whistle, they know which dolphin is calling.

    Dolphins often hunt by themselves but still need to stay connected to the group. Since they can't always see each other, dolphins use their signature whistles to check in with other dolphins hundreds of yards away. “In coastal areas, dolphins exchange whistles even when they're a third of a mile apart,” says Greg Campbell, who studies animals. That means dolphins shout out to group members that might be nearly five football fields away.

    What's amazing is who names the baby dolphin. Not the mother. Not an auntie dolphin or another group member. Scientists believe the baby dolphin itself comes up with the signature whistle. Like human babies, a baby dolphin plays with sounds throughout its first year. While testing its sound skills, a baby dolphin is doing something amazing. It's creating or figuring out its signature whistle. How or why it chooses its signature whistle is not clear. Studies show that most of the time the signature whistle is nothing like its mother's or group members' whistles.

    When the baby dolphin is about a year old, its signature whistle is set. It repeats it often so the other dolphins learn to recognize it.

    Deciphering(破译) dolphin names is just the beginning of figuring out what dolphins communicate about. Do they chat about sharks? Discuss the tides? Maybe they even have a name for people. Someday scientists are to decipher the rest of dolphins' communication.

    In 1971 a young man who grew up very poor was traveling across the country, trying to make a new start for himself. Along the way he had completely run out of（用光了...） money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.

    After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet. The waiter, who was also the owner, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,”the owner said. The young man couldn't believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.

    On the way out of town, he began to understand what the owner did. Maybe nobody dropped the money at all.“Maybe that fellow just knew I was in trouble and he helped me in a way that didn't embarrass(使尴尬)me. So I just made a promise to help other people if I can.”

    Later, he worked very hard and became a rich man. Now he lives near Kansas City. Each year he gives away thousands of dollars. He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Last year, he gave more than $50,000 away in Kansas City.

    Born in the 1950s, shopping malls were once the symbol of the U.S. consumer culture, but many are now dying out.

    Dying shopping malls can be found across the United States, often in middle-class suburbs. Economic decline in certain areas together with an upward trend towards online shopping and new forms of urban shopping centers have pushed the once seemingly unbeatable shopping malls into decline. It is estimated that 15 to 50 percent of shopping malls may close in the coming decades.

    American shopping culture follows its housing culture. Numerous shopping malls were therefore born after the Second World War, as Americans with cars and fat wallets moved to the suburbs. U.S. shopping malls were built at a rapid pace as shoppers fled cities, peaking in the mid-1990s when they were being built at a rate of 140 a year. Thus, too many shopping malls are left though construction has gradually decreased since then.

    Currently, there are around 1,500 shopping malls across the U.S. Most share a handful of similar feature. They usually contain two or three stories of stores separated by walkways. Food courts serve pizza and other fast food. Parking lots are big enough to easily misplace a car.

    Shopping malls in Europe might contain grocery stores or childcare centers, while those in Japan are often built around mass transit (交通枢纽). But the suburban American shopping malls are hard to get to and mainly sell clothes and gifts.

    As many shopping malls became redundant (过剩的), leaders in many U.S. towns who once fought for malls now struggle with how to transform them to new uses. Highland Mall in Texas is being transformed into a community college campus, and Lakeland Mall in Florida now houses a megachurch (大型教会). Others have been redeveloped to include housing, offices and even green space. However, it is hard to imagine every shopping mall meeting the demands for such transformations.

Racing is nothing new for Sebastian Rosado. He was born with cerebral palsy (脑瘫), which affects a person's ability to move. Though most of his life has been limited to a wheel-chair, he has done at least one race a year since 2011.

It was about a decade ago that his mother, Jaime, was training for a race in Puerto Rico, and Sebastian asked if he could accompany her. She'd have to push him in the wheelchair because his arm functions are limited, and she was okay with that. However, the race wouldn't allow it. Then, Sebastian's family decided to make a special race for children like Sebastian. The race gives them a chance to prove that despite being told from a young age that they might not be able to do some things in their lives, they can also become what they wish to be in life.

Sebastian has run it every year using a special walker. Each year, he tries to outdo his previous goal. Instead of just 5 km in 2020, he wanted to attempt to run 21 km over 30 days. Sebastian's plan is to complete the distance by May 9, accounting for completing 1 km, at most, in a day.

Sebastian used to train in a track and field facility close to home, and it's amazing to hear runners telling him things like, "Wow , sometimes I don't have the strength to train but when I see you doing this, I feel that I have no excuse," 62 swimmers are joining Sebastian's challenge this month by swimming 800 meters each one.

Sebastian has a saying that your disability is not in your body, but in your mind. It's really powerful. If you promise yourself you'll do something, you can achieve it by using your mind.

The success of The Pickwick Papers made Dickens very popular. He suddenly found himself at twenty-four the most famous novelist of his day. Busy as his social life was, he worked on two novels at the same time—Oliver Twist and The Pickwick Papers. He was particularly proud of The Pickwick Papers, which was a huge success and was regarded as a comedy (喜剧) masterpiece (杰作). "If I were to live a hundred years and write novels in each, I should never be so proud of any of them as I am proud of The Pickwick Papers," he said.

It has been said of Dickens that he grasped (抓住) the imagination of his readers because his imagination grasped himself. The people in his works were so real that they could make him laugh or cry. When writing Oliver Twist he said that he could not rest until Fagin, the wrongdoer (做坏事的人), had been hanged.

Dickens' marriage to Catherine Hagarth, with whom he had ten children, ended unhappily in 1858. He started to travel about giving readings of his works. His interest in theater gave his novels the qualities that made them suitable for reading aloud on the stage. A tiring travel to the United States affected his health. On June 9, 1870, when he was working on a new novel, he died, as he had wished. He said he wanted to die working.
