There is a story about a man who lost his legs and left arm in an accident. After the accident, only a finger and thumb on his right hand remained.

    He was a brilliant, creative, and educated man. He had gained a lot of experience while traveling around the world, so he became very depressed after his accident. He was afraid that he would spend the rest of his life suffering and would no longer be able to spend his life in a meaningful way. Then, he realized that he still had partial function of his right hand and could still write even though it was very difficult. An idea occurred to him, “Why not write to other people who need encouragement?”

    He wrote to the prison ministry about sending letters to the prisoners. The prison minister replied, “Writing to the prisoners is acceptable, but your letters will not be answered.”

    Filled with excitement, the man knew he could write his letters. He began sending one-way messages of God's love, hope, strength, and encouragement. He wrote twice a week, testing his strength and ability to the limit. He poured his heart and soul into his words and shared his experience, sense of humor, optimism, and faith.

    It was difficult to write those letters, especially without hope of a reply. One day he received a letter from the prison ministry. It was a short note from the officer who monitored and checked the prison mail.

    The letter said, “Please write on the best paper you can afford. Your letters are passed from room to room until they fall to pieces!”

    No matter what circumstances life may present, we all have unique experiences, abilities, and God-given talents. We can discover ways to reach others who desperately need messages of encouragement and strength.

    I want to tell you the story of one of my old friends called Bob，His teachers called him A Troublemaker，They also said that he had no future and no hope. But now he owns a small second -hand bookstore store which makes him enough money to live on and also to support his mother.

    He told me that after he finished grade nine, he went to study at a technical college. He was a pretty bad student so he became one of the gang (一帮) leaders there. Many of them got caught many times for fighting.

    It looked like nothing could change his life. That was until one sad day when his father died. That changed everything.

    After his father died, his mother had to work very hard to make enough money to support the family. He told me that he really pitied his mum after his dad died. He felt that he needed to earn some money rather than let his mum work alone. He loved reading cartoon(卡通)books and had been collecting them for years. As his family was short of money, he decided that he should sell them. He did this by the side of the road where his mother was selling food.

    Soon he realized that his books were very popular. So he decided to set up his own business. He started his business by going around buying cartoon books from other people. He bought them for 25% and then sold them for half price. He could make enough money to help support the family.

    He was a troublemaker to his teachers but he is a hero to me. If you are judged as a bad student or as someone being stupid, I suggest you pay no attention to what they say. Just do your best in everything. Don't give up so easily. Believe in yourself. If you think that you can do it, then you can. Believe me, one day you could be more successful than those persons who looked down upon you.

    Petra and Wadi Rum, Jordan

    When it comes to the world's wonderful desert scenery, Jordan's Petra and Wadi Rum has it. Also known as the Valley of the Moon, this place is one of the best due to its amazing desert canyons (峡谷) and rock walls. Participants love exploring its Burdah and Um Fruth, walking to the impressive ancient city.

Kilimanjaro, Tanzania

    The Rongai Route is the best route if the participants of the walking tour want a quiet climb. The Kili Trail permits travelers to witness the region's wilderness, virgin forests, and rare animals. This route, according to many, is the easiest way to reach the top where the breath-taking 360-dcgree sights of natural wonders await.

    Quebec, Canada

    This special environment made up of both the natural and cultural treasures, where fresh water becomes one with the tides (潮汐) of the sea, makes Quebec one of the interesting walking tour destinations in the world. Here is a track that heads to the Saguenay Fjord National Park which is included in the UNESCO World Heritage Site. Adding to the beauty of Quebec are its sparkling waterfalls, inviting lakes, and rare animals.

    Great Smoky Mountain, US

    This region has been named as the ancestral home of the Cherokee Indians, where rich natural wonders combined with interesting history are the major happenings. The rich natural reserve is evident and enjoyed by walking tour participants. What also makes this destination a popular choice is its reputation as the biggest wilderness on the eastern part of the United States.

    Here are some of the strangest aviation(航空)ideas in recent history.

    Double-Decker Seating

    In 2015, Airbus filed a patent for a design for a double-decker cabin seating arrangement. Passengers would sit on top of the other, with upper-tier passengers climbing steps or a small ladder to reach their seats. While the design does have some advantages, the idea of climbing a ladder during flight seems unreliable.

    Separated Cabins

    This patent was awarded to Airbus. Rather than waiting for a flight to arrive and be cleaned,passengers could simply board a ready cabin, which would be moved into the plane's body as soon as it was ready. When the plane reached its destination, the cabin would be separated again. Different cabins with different kinds of seating or levels of comfort could be used for flights of different lengths or destinations.

    Windowless Cockpits(驾驶舱)

    For ideal design, airplane noses should be long and pointy. But there's the whole "pilots have to fit in the cockpit" problem. Well, what if the cockpit didn't have to go in the nose of the plane? That's part of the thinking behind this Airbus patent application* which suggests replacing the plane's window with a digital viewing surface. Without a window, there's no reason the cockpit needs to go in the front of the plane —it could go in the middle of the plane, or even in the tail.

    Nap Straps (睡眠吊带)

    Airbus is not the only company in the strange patent contest. Boeing's got its own patent, Nap Straps. With this invention, passengers looking for a nap can find an "upright sleep system^" beneath their seat. In action, the whole thing is somewhat like a traction device for someone who's been in a terrible accident.

    Spending money on time-saving services reduces stress and boosts(增进）happiness, according to a new research, but shockingly, few of us do it.

    Whillans, a professor at HBS said, "Buying time helps to protect us from the stress in our lives caused by time pressure, and the feeling that we don't have enough minutes in the day to complete our tasks."

    The effect was clearest in the Canadian experiment, in which 60 working adults were given $40 to spend in two different ways. One weekend, they were told to spend the money on a material purchase—a gift for themselves. The next weekend, they were instructed to spend the $40 on anything that saved them time, from paying the neighbor ' s kid to run errands (跑腿）to taking an Uber instead of a bus.

    〇n the day they made the time-saving purchase, they felt happier, in a better mood, and lower feelings of time stress than on the day they bought a material purchase," said Whillans.

    The biggest surprise to the researchers was how few people would spend money on time-saving services. When they asked 98 working adults how they would spend a "windfall" of $40, only two percent named a purchase that would save them time.

    "One reason," said Whillans, is that we're very bad at remembering how much we hate doing certain tasks once the suffering has passed. That makes us less likely to take active steps to avoid that overburdened feeling in the future. "But another possible cause is good old-fashioned guilt." If you feel guilty about getting someone to clean your house for you, then you might get less happiness from outsourcing (夕卜包）that task," said Whillans, "or you might just be less likely to spend your money in that way."

    It seems we're always being told to get more sleep. Studies suggest spending less time on sleep can lead to obesity(肥胖) and even cancer. You might even find yourself with a head full of false memories. But rarely does science explore the dark side of sleeping too much. That's because few of us in today's busy world have the luck of exploring that option.

    In an August 2018 study, published in the Journal of the American Heart Association, researchers researched the sleep patterns of those "fortunate" few and found they may not be so lucky after all. In fact, they found people who get more than eight hours of sleep have greater health risk compared to those who sleep together less than seven hours. What's more, sleep-aholics-those who manage to get 10 hours a night-stand a 30 percent higher chance of dying compared to the seven-hour crowd.

    The wide-ranging global study involved(涉及) more than three million people who self-reported on their sleep habits and came to an eye-opening conclusion: If you tend to sleep a lot, you may want to buy an alarm clock. As with all things in life, sleep is best taken in moderation(适度).

    You may be thinking: What if I only sleep in on Saturday and Sunday, am I still at risk? The answer is yes, according to a 2019 study published in Current Biology.  Researchers discovered that even if a person sleeps more than seven hours on the weekends but still sleeps less than that on weeknights, they are at risk of gaining weight and developing sensitivity to insulin, which controls the level of sugar in blood.

    For the study, 36 participants were divided into three groups that each had a different sleep schedule: nine hours every night, five hours every night, and five hours from Monday to Friday and sleeping much on weekends. People who get too much sleep tend to feel tired and lack energy. Also, both sleep-deprived(睡眠不足的) groups consume more food and gain weight.
