One day after school, I went to the teacher's office to see my teacher, but nobody was there. As I was about to leave, I noticed a piece of paper on the floor. I picked it up and saw the words "FINAL-TERM EXAMINATION" at the top. I put the paper into my school bag secretly and ran out of the room.

 After I came back home, I took out the paper quickly. It was the exam paper of my worst subject, History. I felt excited. My heart beat fast. I took out my History book and started working on the answer. I had never answered any questions so seriously.

 On the day of the History exam, I went into the exam hall confidently. When the paper was sent to me, I dreamt of getting the highest mark in the whole grade and could not help smiling. "My History teacher always encouraged me to work hard and get better grades, but I let him down time and time again. This time I will give him a big surprise," I thought.

 When  the  teacher  said  we could  start,  I turned  the  paper  over. To my surprise,  all  the questions were different. Later I felt nervous. In the end, I almost left the paper undone. After the exam. I ran to the toilet, took out the paper and carefully read it from the top. Oh! It was last year's exam paper. I read all the questions but I hadn't read the date.

 This is a lesson in which I know I have to put my feet on the ground. I regretted doing such a silly thing. After that, I told my teacher the truth and I promised to be honest. From then on, I worked harder than ever before.

    Once upon a time, there lived a rich man. He had a servant (仆人). He and the servant(仆人) loved wine and good food very much. Each time the rich man left his home, the servant would drink the wine and eat up all the nice food in the house. The rich man knew what his servant did, but he had never caught his servant doing that.

    One morning, when he left home, he said to the servant, “Here are two bottles of poison (毒药) and some nice food in the house. You must take care of them.” With these words, he went out.

    But the servant knew that the rich man had said was untrue. After the rich man was away from his home, he enjoyed a nice meal. Because he drank too much, he was drunk and fell to the ground. When the rich man came back, he couldn't find his food and his wine. He became very angry. He woke the servant up. But the servant told his story very well. He said a cat had eaten up everything. He was afraid to be punished, so he drank the poison to kill himself.

    I have a twin brother, Bob. He is taller than me. His hair is shorter than mine. Many people think we must have many things in common. But in fact this is not true. Bob is more outgoing than me. When my parents' friends come to our house, Bob often sits there and talks to them. But I often sit there and say nothing. Bob likes reading, cooking and drawing. I just like swimming and playing basketball. He has more hobbies than me, but he is not as athletic(擅长运动的) as me. Because Bob does better than me at school, my mom often says to me, “Bob is younger than you, but he can get better grades, you should learn from him.” We both like eating fast food and listening to music.

    Mona doesn't like to ask people for help. But it is hard for her to perform daily activities on her own. She is almost 13, yet she is no larger than a 5-year-old. Mona has trouble keeping her balance and can't walk very far. When she uses a wheelchair, she can't push it herself.

    Fortunately, Mona has a wonderful service dog named Sam. A service dog is a dog that has been trained to assist someone who has a physical problem. Sam lets Mona lean on him when she walks. He also pulls her wheelchair and turns lights on and off. When Mona drops something, Sam picks it up. He even pulls her socks off at night.

    Sam also helps Mona with everyday tasks at school. He carries her books from class to class in a special backpack. He puts Mona's completed assignments in her teachers' homework trays. In the lunchroom he throws away her trash.

    Besides making Mona less dependent on other people, Sam helps her lead a fuller life. Mona's classmates flock around Sam like geese. This has helped her make friends. Sam also helps Mona be more active. With his aid, she raised over $500 in walk-a-thon for her local humane society.

    Because of Sam, Mona doesn't have to ask people for help. Sam brings her closer to other kids. And he even helps her contribute to her community.
