     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.

      Once upon a time all feelings went to an island for a vacation, and each was having a good time. Suddenly, a warning of a strong storm was announced, so all rushed to their boats. Yet, Love did not wish to run away quickly. There was so much to do. But as the clouds darkened, Love realized it was time to leave. But there were no boats to use. Love looked around with hope.

      Just then Richness was passing by Love in a large boat. Love shouted, "Richness, can you take me with you?" Richness answered, "No, I can't. There is a lot of gold and silver in my boat. There is no place here for you."

Love decided to ask Vanity (虚荣) who was also passing by in a beautiful boat for help. But Vanity said with a cold voice, "No, I can't take you with me. My boat will get dirty with your muddy feet."

      Sorrow passed by after some time. Again, Love asked for help. But it was useless. "No, I can't take you with me. I am so sad. I want to be by myself. "

    When Happiness passed by a few minutes later, Love again called for help. But Happiness was so happy that it hardly cared about anyone else.

      Love was growing worried and hopeless. Just then somebody called out, "Come, Love, I will take you with me." Love did not know who was being so kind, but jumped onto the boat happily.

      After getting off the boat, Love met Knowledge. Love asked, "Knowledge, do you know who was so kind to give me a lift when no one else wished to help?"

      Knowledge smiled, "Oh, that was Time."

      "Time?" asked Love. "But why did Time help me?" Knowledge smiled with deep wisdom and answered, "Because only Time is able to understand how valuable Love is."

    Today I went to Sam's school in the UK. It was really different from my school in China.

    Girls wore grey skirts and white shirts, boys wore grey trousers, and everyone wore the school tie.

    Some of Sam's lessons were a bit strange for me. We were reading Shakespeare in the English lesson, and there were quite some old words like “thou” and “thee” to mean “you”. In history we studied 20th Century China. It was strange hearing a foreign side of history—and hearing English people trying to say all our Chinese names!

    Classes were also a lot more relaxing than in China. Teachers were called “sir” or “miss”, everyone shouted answers and raised their hands in classes. It was more like a debate than a class. A bell rang at the end of each lesson and everyone jumped up to go to the next class.

    At break we bought potato chips and cookies in the dining room. Lunch was later than in China at 1 o'clock. We had big plates of pie with carrots. For dessert there was hot sweet rice called rice pudding.

    It was good that I'd had an excellent lunch, because at Sam's school, Monday afternoons are taken up with sports.

    I played my first game of netball—a bit like basketball, but with some differences. Fortunately(幸运的是), I'd had a quick look in the rule book before I tried to join in the game.

    One day Mrs. Smith invited many people to her house. She wanted to cook them a good dinner of meat and soup. She had five daughters. They were all busy. Mrs. Smith was busy, too. She forgot to put any salt into the soup. So she asked Mary, one of her daughters, to help her. “I can't, Mum. I'm busy now.” said Mary. She asked the other girls, but got the same answer. So she did it herself.

    Now, Mary thought she should help her mother. So she put some salt into the soup. And then all the other girls did the same.

    Mrs. Smith put the soup on the table. The friends took a little soup and their eyes opened wide. She took the soup, then she knew. “Which of you girls put salt into the soup?” she asked. “I did, Mum.” All the five girls said together.

    On September 13th, I woke up in the best mood. It was a late start, so I got to sleep in. Not only did I get my full eight hours of sleep, but an additional two more hours as well. I got ready, danced in my room to my favorite music while I picked out my clothes, made my lunch, and was on my way to school. I arrived at 9: 50 a. m. Little did I know, in the next 20 minutes, my life would change forever. As I got out of my classroom, there he was, holding the gun.

    Although everything happened so fast, in a matter of about 4 minutes, I remember it clearly. I remember every face I saw, and I remember every sound I heard. I remember the fear and the panic of the unknown. And lastly, I remember running. Running for my life. I ran down the stairs, out of the school's front doors, and down the street to the primary school. I remember looking down at my feet. As I looked down I thought to myself, "How am I running so fast?"

    I finally made it to a safe classroom, and 20 other students and I settled in for lockdown. We stayed close to one another and cried. It felt as though the tears going down our faces would never stop. We passed our phones around to text our loved ones that we were safe and that there was a school shooter, shots were fired, and 4 students were injured thus far.

    The lockdown lasted about 30 minutes, even though it felt like forever. Our headmaster made his way to our room and explained that the shooter had been caught and we were all going to make our way to the football field.

    It was raining heavily as I was walking up the hill towards the station at six o'clock on a Saturday morning. Just as I was crossing the road near the top of the hill, a car came around the corner. It was traveling very fast. Suddenly it hit a lamp post (路灯杆) and turned over.

    I ran to the car to help the driver at once. He was badly hurt and there was a lot of blood on his face. Many people came to see what had happened and there was nothing we could do. A young woman hurried into the station and phoned for an ambulance (救护车). A policeman arrived a few minutes later and asked me a lot of questions about the accident. After a while the ambulance arrived and the driver was sent to the hospital.

    On Monday morning I went to the hospital to see the man. The doctor told me that he was much better, and he would leave the hospital after a few days' rest.
