Tail Spin

    Two dolphins race around in a big pool in the Ocean Park. The smaller dolphin Grace, shown off a few of her tricks, turning around and waving hello to the crowd. The most amazing thing about her, however, is that she's even swimming at all. She doesn't have a tail.

Grace lost her tail as a baby when she got caught up in a fish trap. When the dolphin arrived at the Ocean Park in December 2005, she was fighting for her life. “Is she going to make it?” Her trainer, Abbey Stone, feared the worst. Grace did make it — but her tail didn't. She ended up losing her flukes and the lower part of her peduncle.

Over the past six years, she has learned to swim without her tail. Dolphins swim by moving their flukes and peduncle up and down. Grace taught herself to move another way—like a fish! She pushed herself forward through the water by moving her peduncles from side to side.

    The movement put harmful pressure on Grace's backbone. So a company offered to create a man-made tail for her. The tail had to be strong enough to stay on Grace as she swam but soft enough that it wouldn't hurt her.

    The first time Grace wore the artificial tail. She soon shook it off and let it sink in the bottom of the pool. Now, she is still learning to use the tail. Some days she wears it for an hour at a time, others not at all. “The tail isn't

necessary for her to feel comfortable,” says Stone, “but it helps to keep that range of motion(动作) and build muscles(肌肉).”

    Now, the dolphin is about to get an even happier ending. This month, Grace will star in Dolphin Tale, a film that focus on her rescue and recovery. Her progress has inspired more than just a new movie. Many people travel from near and far to meet her. Seeing Grace swim with her man-made tail gives people so much courage.

    After suffering through many months of unemployment  (失业). my wife and I moved this week from Colorado to Ohio. where she was starting a new job. Not knowing anybody there. we were pretty concerned about how we'd get our entire home unloaded (卸下) without killing ourselves.

    We made a phone call to hire (临时雇用) a couple of college students to help with all the heavy lifting once we got there. But one neighbor after another stopped by to help us. What ? Have we moved to some other country ? Maybe we've died and gone to heaven!     

    Unloading actually became fun and joy because there were so many wonderful new friends to help when we worked. The more people helped. the easier the work became. We were afraid the job might take days for the two of us alone. but it was finished in a few hours. Many total strangers would either walk by the sidewalk or drive by to ask us if we were moving in. Many were happy that this old house that had sat empty for so long was coming to life again. We were invited to an outdoor meal yesterday by neighbors on the same street.

    All the time. my brain was resting on this new sense of hope that people can be so friendly to strangers. Among all the conversation were lots of offers to help each other in all kinds of ways. It's wonderful to live in such a kind little town. I feel so grateful to be here. and wish the rest of the world could see how an entire community can model  (做榜样) what it's like to help each other.

    Since 2008, hunters have illegally killed more than 3000 rhinos in South Africa. The International Union for Conservation of Nature warns that rhinos may die out by 2026. People who hunt and kill illegally are called poachers. The most effective way to watch for and prevent illegal hunting is from the air. However, piloted flights are too costly. Fortunately, some Spanish college students have invented a drone (无人机) that can observe more places than a plane.

    Arnau Garcia is an aeronautical (航空学的) engineering student at the Polytechnic Institute of Catalonia, in Spain. He says observers from the air have trouble finding poachers when they hide under the trees. Mr. Garcia and other students have worked with the drone manufacturer HEMAV to help find the hidden poachers. They make it by using the thermal camera, which is especially sensitive to body heat. Even when the poachers keep still, it can also keep track of them.

    The drone can fly in the wind up to 55 kilometers per hour. It has an autopilot system, so it memorizes the flight path. The drone also has a microphone, a video camera and a GPS system. These permit it to report accurately where a picture is taken. After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.

    Experts say the drone can fly as far as 70 kilometers from the base. It means that it could quickly observe large areas for poachers. However, the same search operation would take days for human observers. Thanks to the drone, many poachers have been caught and the number of rhinos is on the increase. In addition, HEMAV has received an increasing number of orders for the drone. Even South African national park officials attempt to fill the air with drones.

    Mark Twain, the famous American writer and a great master of humor, liked to play jokes on others. But once a joke was played on him. One day Mark Twain was invited to give a talk in a small town. At lunch he met a young man,one of his friends.

    The young man said that he had an uncle with him. He told Mark Twain that his uncle never laughed or smiled, and that nobody and nothing was able to make his uncle smile or laugh.

    “You bring your uncle to my talk this evening,” said Mark Twain. “I'm sure I can make him laugh.”

    That evening the young man and his uncle sat in the front. Mark Twain began to speak. He told several funny stories and made everyone in the room laugh. But the man never even smiled. Mark Twain told more funny stories, but the old man still kept quiet. Mark Twain continued to tell his funny stories. Finally he stopped. He was tired and quite disappointed.

    Some days later, Mark Twain told another friend what had happened. “Oh,” said his friend,“I know that man. He's been deaf for years.”

    Today we talk about a time when half the world is waking from the dark, cold winter months. Spring! We often describe “spring” as a time of rebirth, renewal and awakening. Many trees are blossoming and early flowers are pushing through the earth. Things are coming to life!

    But the word “spring” is not just a season. It is also a verb that means something going on or coming out quickly. When you put “spring” and “life” together, you will get “spring to life”. This expression means something suddenly becomes very active or perhaps seems more alive! You may “spring to life” after hearing that a distant friend will be visiting you. Or maybe your favorite soccer team finally “sprang to life” in the second half, played well and won the match.

    Now, besides being a season and a verb the noun “spring” refers to a metal coil (线圈) that is wound tightly. When the coil unwinds, it often jumps. So, we often say a person “has a spring in his step” if he is lively and active. He might even appear to jump, or bounce a little when he walks.

    There is another way we use “spring” as a description. In the case of a “spring chicken”, “spring” means young. However, “spring chicken” is also an informal, humorous way to refer to someone who isn't young at all. So, we use this expression in the negative form, as in “no spring chicken”. For example, let's say you know an 85-year-old man who decides to run a marathon, even though he has never exercised before. You could say, “That's amazing! After all, he's no spring chicken.”

    But be careful when using this expression. It could be a little disrespectful. Let's say your boss shows you a picture of his wife, and you say, “Wow, she's no spring chicken.” That response would be disrespectful and a bad career move.

    LaVonn was helping out in her dad's store when a little boy, about five or six years old, came in. He was wearing a brown and oversized coat with dirty, old clothes beneath it. His shoes were broken, and only one had lace (鞋带). The boy looked around the store, picked up several items, examined them one by one and then carefully put them back on the shelf.

    LaVonn's dad walked over to the child and asked if he could help. The little boy said, "I'm looking for a gift for my brother." After 20 minutes, the child picked up a toy airplane. He held it carefully in his hands as if it were made of glass and carried it to LaVonn's father.

    "How much is this?" he asked. "My brother loves airplanes." LaVonn's dad answered, "How much money do you have?" The little boy reached into his coat and pulled out some small change (零钱). He spread his money out on the table and began to count. "I have twenty-seven cents," he answered. Her dad picked up the coins and said, "The airplane costs exactly twenty-seven cents! Wait here and I'll pack it up for you."

    The little boy walked out of the store with the gift and a smile of total satisfaction on his face. LaVonn made her way back to the shelf and she found the plane was priced at $11.98.She never mentioned it to her father. Her father didn't say anything more about it either, but she realized later, "My best gift that Christmas was seeing my dad's love in action."
