     Sixteen years ago, a boy gave me an important gift. It was a smile.

      It was the early autumn of my first year at a middle school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

     Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk with anyone about my problems.

Then one day, my classmates were talking happily with their friends, but I was sitting at my desk unhappily as usual.  At that moment, a boy entered the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, with a smile.

    Suddenly, I felt the touch of something bright and friendly. It made me feel happy and warm. That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now.

    One day I asked him why he had smiled, but he couldn't remember doing so!

     It doesn't matter because all the dark days have gone. I believe that the world is what you think it is. If you think it is lonely, you might always be alone. So smile at the world and it will smile back.

    It is sunny and warm today. A dog is sleeping.

    A panda comes to the dog and says, “You are a lazy dog. You don't do anything every day.”

    “What do I need to do?” asks the dog.

    “My owner(主人) gives me food to eat. My owner takes me out for a walk. My owner loves me. Ha! I eat, I go out for a walk and I sleep. I don't have any other things to do.”

    “But don't you have any ambitions(抱负)?” asks the panda.

    “Ambitions? What do I need ambitions to do? I'm just a dog,” says the dog.

    “What ambitions do you have?”

    “I often go to other countries and make friends with people there. So I can show the world that Chinese are friendly,” answers the panda.

    “Oh,” says the dog, “maybe I should do something for others.”

    I graduated from a college recently and moved to Washington by myself.  While I was in college, it was really easy to meet new people. But “out in the real world”, I was finding it really hard. I live in a big city, and it seems like everyone around me is busy or already has all the friends they want. I was feeling so discouraged (沮丧的) and I didn't know what to do, so I called my sister for some advice.

    My sister is five years older than I am, so she's been though all this already. She's been helping me with my problems all my life. When I explained my problem, she understood completely. She said, “Why don't you try meeting people online?”

  “Online? Are you kidding? ” I asked, “A friend of mine chatted with a guy online, and when she finally met him face to face, he was nothing like what he said.”

    My sister laughed, “You don't have to look for dates online,” she said, “But you can find other people like you—people who have just moved to town and want make some new friends. When I first moved to New York after college, I found a book club and a football team online. I met a lot of people that way. ”

    “But you don't even like football!” I said. 

    “I know,” she replied, “But that didn't matter. I still had a lot of fun. You played volleyball in college. Why don't you look for a volleyball team to join?  Or an art class? ”

    “Yeah! I saw a website about volunteering the other day,” I said, “I could volunteer for an organization here in Washington. I bet I could meet a lot of really nice people that way. ”

    “Good idea!” my sister answered excitedly. “Hey, you might even meet the perfect guy.”

    “OK, now you're starting to sound like Mom,” I said. “Thanks a lot for the advice. I'm going online right now. I'll let you know what happens. Will you be home tonight?”

    “No, but I'll be here all day tomorrow, so give me a call,” my sister replied. “Good luck!”

    Science fiction is a popular kind of writing, and many people think of Jules Verne(儒勒·凡尔纳) as the father of science fiction. He was born in France in 1828. His father wanted him to become a lawyer, but from his early 20s Verne decided to become a writer. At first he wrote plays for the theater. Then, in 1863, he wrote a story called Five Weeks in a Balloon. The success of this book encouraged him to write more stories such as A Journey to the Center of the Earth(1864) and From the Earth to the Moon(1865).

    In the 19th century, many people were interested in science and inventions. Jules Verne wrote about scientific subjects in his stories and, as a result, they were very popular. Verne's writing included many predictions(预言) for the 20th century and many of them came true. He described space flight, movies, and air conditioning, a long time before they appeared. These books were very successful and they made Verne rich.

    Jules Verne's books have been the subjects for many movies. 20, 000 Leagues under the Sea was a successful movie for Walt Disney. It was the first time that Disney movie had used real actors instead of cartoon drawings. Around the World in Eighty Days is another famous movie based on one of Verne's books. The main character is an Englishman called Phileas Fogg. For him, the most important thing is to be always on time!
