“Do you believe in life after death?” Jack's boss asked Jack.

“Yes, Sir.”

“Well, then, that makes everything just fine,” the boss went on. “About an hour after you left yesterday to go to your grandfather's funeral(葬礼), he dropped in to see you.”

    When I was 13 years old, the doctor said that I had a kind of attention disorder. So when everyone else in the class was focusing on tasks, I couldn't.

    In my first class, Mrs Green asked us to read a story and then write on it within 45 minutes. I raised my hand right away and said, "Mrs Green, you see, I have attention problems. I might not be able to do that."

    She looked at me and said, "You are no different from your classmates, young man." I tried, but I didn't finish the reading. So I took it home.

    In my bedroom, it was so quiet and the story suddenly became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn't get much education. But Louis didn't give up. Instead, he invented a reading system which opened up a new world to the blind. Wasn't I the "blind" in my class, being made to learn like the "sighted (有视力的)" students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was no different from others. If Louis could find his way out of his problems, why should I ever give up? I didn't expect anything when I handed in my paper to Mrs Green, so when it came back to me the next day with an "A" on it, I couldn't believe my eyes. At the bottom of the paper were these words, "See what you can do when you keep trying."

    One day in a restaurant, the American writer Anne Herbert wrote this sentence on a piece of paper: "Random(任意的) actions of kindness." Later she repeated it in an interview on a TV show, and it soon caught people's eyes and made people think about how small "kind" actions could make our daily lives better.

    One rainy night, a woman was standing at a bus stop waiting for the bus. A man came by on a motorcycle and offered to give her a ride. Of course, the woman said no. It would be crazy to accept a ride from a stranger on a motorcycle. Suddenly the man reached out and put a 50-dollar bill in her hand. He said, "Please take a taxi. It hurts me to see you standing here in the rain." Before she could refuse, he left quickly on his motorcycle.

    Kind actions can be contagious. Once, a woman was going through a toll station(收费站) on a highway. Instead of paying for one ticket, she asked for two. She said to the toll collector, "The second ticket is for the car behind me." She didn't know the person in that car. She just did it without thinking more. So when the next car came up, the toll collector said to the driver, "You don't have to pay. The woman in the blue car just paid for you." The driver was so surprised that he decided to pay for the person behind him. This continued with 14 drivers that day.

    So just imagine what the world will be like if we all practice random actions of kindness from time to time?

    Once there was a boy. He loved sweets(糖果) very much. He always asked his father for sweets.

    The boy's father thought hard about how to stop the child asking for so many sweets. There was a saint(圣人) living near their house. The boy's father decided to take the boy to him. He thought he might make the child give up (放弃) sweets.

    So they went to the saint. The father said," Great man, could you ask my son to stop asking for sweets all the time?" But it was difficult for the saint, because he liked sweets, too. Then he told the father to bring his son back after one month.

    During that month, the saint tried to stop eating sweets. At last, he did it. When the boy and his father went back a month later, the saint had a long talk with the boy. From then on, the boy did not ask for sweets any more.

    The boy's father felt surprised and asked, "Why didn't you ask my son to give up sweets when we came to you a month ago?" The saint answered," How could I ask a boy to give up sweets when I loved sweets myself? During the last month, I gave up eating sweets."

    A person's example(例子) is much more stronger(更有力的) than just his words. When we ask someone to do something, we must do it ourselves, too.

    We should not use more water than we actually need. If we do, we will not have enough water in the future.{#blank#}1{#/blank#}It is not a difficult question to answer. If we remove more fresh water than nature replaces, we have taken too much.

    Many cities run campaigns (运动) to get people to stop wasting water. They show them ways they can cut back on water use.{#blank#}2{#/blank#}What's more, they carry out programs that offer money to reduce water use. For example, they give people shower heads and toilets that use less water.{#blank#}3{#/blank#}

    Another threat (威胁) to our water supply is pollution. When our sources of fresh water get polluted, we can no longer use this water. This also endangers (危及) the animals that depend on the water.

    {#blank#}4{#/blank#}We can save lots of water by not letting taps (水龙头) run while we brush our teeth or by turning off taps right after washing hands. By collecting cold water when we're taking warm showers, we can also save water.{#blank#}5{#/blank#}In this way, we can make full use of water.

Martin Strel is a swimmer, who is best known for swimming the big rivers. Martin holds Guinness World Records for swimming the Danube River, the Mississippi River, the Yangtze River and the Amazon River. 

Of all his achievements (成就), the greatest is his Amazon River swim: The Amazon is one of the largest and most dangerous rivers in the world. Many swimmers failed to swim it. Martin decided to make history and show the world that people could achieve their dreams with hard work and perseverance (毅力). 

On 8th April 2007, Martin completed his Amazon River swim all the way. He spent 67 days swimming about 3, 274 miles in total. His hard work and perseverance at last bore fruit. He became a big shot as well as a worldwide hero. 

Many people still cannot believe what he has done so far and they describe him as"the Craziest Man in the World". In 2009, American filmmakers produced a documentary called Big River Man. And the book, The Man Who Swam the Amazon, has been sold in many countries. The story of Martin's perseverance and hard work has encouraged many people. 

Does Martin swim for money? That's not the truth. Instead, he wants to teach people about the importance of keeping water clean. Martin has always been looking for the challenges of the impossible. What is his next?
