    It was July 17th of 2017. The little helpless girl, who had trouble walking, was going out into the wide world. In June 2016, I got the idea that I was going to America as an exchange student. With tears in my eyes, I said goodbye to my family.

    After I finally arrived at the airport in Burlington, Vermont. I was welcomed by my host family. They didn't know much about my disability. “I hobble a little, but I don't see it as a problem.” I think it's the will that decides what you can and cannot do, and the disability doesn't matter!

    Before I went to the US, I knew I was going to miss home. But I went! Why? I've been a fighter ever since I decided not to give up my breath when I was born! My mother wrote my host mom an e-mail and told her about my hard birth so they would understand. I remember clearly after she finished reading it, she came into the room, gave me a big hug and said, “You are a fighter.” My host family supported me so much during the year. In school, small notes were sent out to all my teachers, by e-mail, to tell them about my disability. Everything worked greatly.

    By the end of my year, exchange students were asked to talk about our years. I spoke in front of about 100 people! I was extremely proud of my “speech”. The following day some teachers stopped me and said, “Your speech was the best one.”

    My year in Vermont was the best thing I've done so far! I proved I AM A FIGHTER and that NOTHING IS IMPOSSIBLE!

    Mr. Smith made many tests with different animals. They found that the monkey was the cleverest of all the animals. One day Mr. Smith put a monkey in a room. He also put some small boxes in it. In one of the boxes there was some food. “How long will it take the monkey to find the food?” Mr. Smith said to himself. “Let me wait and see.” He left the room and waited outside. Three minutes later, he put his eye to the keyhole (猫眼). What did he see? He saw the eye of the monkey. The monkey was on the other side of the door and looked at Mr. Smith through the keyhole.

    I was in the park with my elder sister, Cathy, on Friday. My sister left her jacket on a chair while we talked to some friends. When we went back to the chair, a girl in a red T-shirt was sitting there. She had some money in her hand. When she saw us, she stood up and walked away.

    I asked my sister, "Did you have any money in your jacket?"

    She said, "Yes, Anna, I did."

    I said, "Look in your jacket quickly."

    Cathy looked in her jacket, but her money was not there.

    "That girl stole(偷) it!" I said, and we both ran after her. We caught her quickly.

    My sister was very angry and she said, "Give me the money." The girl gave the money to Cathy and ran away. We both ran after her, but we lost her.

    Then we went home. But before we could tell our parents, my mother said to Cathy, "You left your money at home. It's on the table in the sitting room. You must be more careful with money."

    So the girl in the red T-shirt was not a thief! She probably thought we were thieves! We felt terrible.

    Please telephone us if you know this girl! We are very sorry for our mistake. We would like to say sorry to her and give the money back to her.

    Our number is 512667. My name is Anna.

    The famous scientist and thinker, Charles Darwin, was born on February 12, 1809. His family lived not far from the River Severn, England. As a boy, Charles liked to go for walks in the fields and forests. He enjoyed watching nature, and comparing what he saw with everything he had read in science books. He also liked collecting very much. He collected many things, birds, eggs, stones and leaves.

    At sixteen Darwin was sent to Edinburgh University to become a doctor. But he was interested in the history of nature.

    Then he was sent to study in Cambridge University. There he studied until 1831.

    Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it. The trip lasted almost five years. Darwin saw many new plants and animals. He collected all kinds of plants.

    In 1842 Darwin went to live in Kent, and there he continued his studies of change in nature. Darwin understood that plants and animals are not always the same, and that they really change. By 1859 Darwin had finished his famous book The Origin of Species.

    In 1871 Darwin wrote another important book, the Theory of Evolution.

    Darwin continued his studies in science until he died in 1882.
