    I'm David. Long ago I came to the city near my hometown to find a job. I met all kinds of difficulties and I used up all my money soon.

    It was dark outside one day. I got on a bus quietly. Suddenly, a passenger cried in a loud voice, "someone has stolen my money!" I felt nervous, because his money was in my hand. Some people suggested the driver drive the bus to the police station, but some were against it because they were in a hurry to go back home. The whole bus was very noisy. The driver then stopped the bus by the roadside and turned on the lights. At that time, one passenger said, "Turn off the lights and give the thief(小简)a chance to take out the money."Then the bus got dark.

    When I was still thinking about whether to take out the money or not, the lights were turned on again. There was no money on the floor. Someone said, "Give him one more chance." Then the lights were turned off again. I became even more nervous. The lights were turned on again but they got the same result.

    Then the passengers fell into an open discussion. Later, someone said, "Give him the last chance!" I felt awakened(醒悟的) and took out all the money when the lights were turned off again.

    For many years I have been grateful to those who gave me three chances. When the first and Second chances come, you may not be prepared well or don't have enough courage to act. When the third chance comes, you should know clearly what you should do.

    Imagine this. Somebody hides free books in the subway for you to find and read. Sound exciting? Well, British actress Emma Watson, 26, is doing it! She is known for acting as Hermione Granger in the Harry Potter movies.

    Watson hid 100 copies of a book called Mom & Me & Mom (2013) in London's subway. The book is an autobiography（自传）from US writer Maya Angelou. It tells about the writer's relationship with her mother. These books were put in different places in the subway. People saw Watson doing the same thing in the New York Subway this month.

    With each book, there is a handwritten note by Watson. She asked people to "take special care" of the books if they find them. She also wrote that "when you are finished, please leave it on the subway again for someone else to find".

    Watson's work is part of a movement called Books on the Underground. It calls on people to leave their books on the subway so other people can enjoy them too.

    Hollie Belton, a woman in London, started the movement in 2012. She loves reading on the subway. She noticed that a lot of people shared her habit, so she got the idea. Over the years, Belton has left over 2,000 books of her own. The movement has attracted more and more people.

    Watson is a book lover as well. That's why she tried it. Earlier this year, Watson set up her own online book club Our Shared Shelf. She reads a book every month with others. Mom & Me & Mom is the club's book for November.

    My husband had just bought a new washing machine for me. I decided to use it and I washed a lot of things.

    Everything worked well, I got ready for school as usual.

    When the bell rang and the students came in, I greeted them and told them what we were going to do that day.

    When I turned around to write on the blackboard, the class broke out into a roar(大笑声).

    They laughed and laughed. They laughed so much, in fact, that I was afraid the headmaster would be in to see all this.

    I asked the class to stop, but the more I talked, the more they laughed. I decided to pay no attention to them, and continued to write on the blackboard. When I did this, they roared even more.

    Finally, the teacher who had the room next to mine came in to see what all the laughter was about. When he came in, he started laughing, too! "Good heavens," I said," Will someone please tell me what is so funny?" "Oh, God," said the teacher." You have a brown sock stuck to the back of your shirt!"

    So that's how I found my husband's missing sock.

   "Oh, well," I said to the class." Let's just say you have had an unforgettable lesson on static electric(静电)."

    Johnny is a lovely fish. He lives in the sea. He is very lonely. He wants to find a friend. And the friend looks like him. Johnny sees an ink fish. The ink fish has eight legs. He doesn't look like Johnny. So Johnny goes away.

    Johnny meets a shark. He wants to say hello to the shark. But the shark opens his big mouth and wants to cat him. Johnny runs away quickly.

    Johnny is tired and hungry. He wants to have a rest. Then he sees a round fish. She says to him." Hello! Would you like to be my friend?"

    Johnny answers," Of course! But you are round, I am fat. You don't look like me." The round fish says," But we are both fishes."

    Johnny thinks and says," You are right. Let's be friends." They become good friends.

    After I finished college, I couldn't find a job in Los Angeles. At last I had to move to Las Vegas but left my family behind. I missed them all week, and I went home on most weekends to see them. I often rented a car because I would often have lots of problems on the way to Los Angeles or to Las Vegas if I drove my poor car.

    One time I decided to save money, and I drove my car. It got to California, but on the way back to Vegas it was broken. I didn't know what I should do. Then a middle-aged man drove up. He put in some coolant and repaired my car. He made it start soon.

    I gave him the $12 in my wallet, and he said he would use it for the next car. Then I knew that he was a mechanic who drove up and down the highway each weekend to help the drivers in trouble.

    Now fifteen years has passed, but I still think about what a great man he is.
