It was nearly seven o'clock, when a man walked into a bar, ordered a drink and turned to watch the television.

    The seven o'clock news was on and it was showing a man standing on top of a tall building. He was looking down at the crowd of people below.

    On the ground, a police officer with a megaphone(扩音器)was trying to tell him not to jump.

    "Let's talk about your problem," the police officer was saying. "Perhaps we can help you."

    The man turned to the bartender(酒吧侍者)and said, "I bet you a hundred dollars he doesn't jump.

    The bartender looked at him. "You're offering me a hundred dollars if he jumps? Is that right?"

    "Yes. I don't think he'll jump."

    The bartender smiled. "OK. You've got a bet."

    The man turned back to the TV and watched it carefully. The bartender, however, did not seem to be very interested. He continued washing glasses and serving the other customers.

    Then, after about five minutes, the man on the building threw himself off the building and fell to the ground.

    The man in the bar turned to the bartender.

    "He jumped," he said. "You win."

    He held out a hundred dollar bill to the bartender, but the bartender would not take it.

    "I can't take your money," he said. "I knew I couldn't lose. That story was on the six o'clock news. I saw him jump."

    "Well, yes, so did I," the man said, "but I didn't think he'd do such a stupid thing twice."

    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 breakfast, 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.

    John Brown, an office worker, lives in Washington. He inherited $1,000,000 after his parents died. He didn't feel happy at all. His college friends were looking for their first jobs, but he didn't have to. John decided to keep living a simple life like everyone else. He didn't tell any of his friends and gave$100,000 of his money to a charity that helped poor children. Today he is 36, and he still wears cheap clothes and drives a small car only, but he is much happier.

    So far, John has helped 15 children from poor countries all over the world, $200 a month for each. The child does not receive the money in cash（现金）. The money is paid for the child's education, food, medical care and clothing. John receives a report each year on the child's progress. They can write to each other, but usually the children do not speak English.

    Once John went to meet a little girl he was helping in Africa. He said that the meeting was exciting." When I met her, I felt very happy. He said. "I saw that the money was used for a very good plan. It brought me closer to the child in a way that only giving money cannot." "I want to do everything I can. I will go on helping those children in need." he added.

    When scientist Jessica Wade realized how hard it was to find information about women scientists, she decided to help solve that problem. She has now added the stories of over 300 female scientists to Wikipedia.

    Dr. Wade has always been interested in science. But as she kept going in science and learned more about amazing women scientists, she was surprised to learn that they didn't have Wikipedia pages.

    Wikipedia is the world's largest encyclopedia, and the world's 5th most popular website. What makes it special is that anybody can add to or change it. But even though Wikipedia has close to 6 million articles. Dr. Wade noticed that "It doesn't have the stories of many amazing women in science." She says that 83% of the biographies on Wikipedia are about men.

    So, in January. 2018 she decided to write one Wikipedia article about a female scientist every day. She doesn't get paid, but it has become her second job. So far, she has created 306 Wikipedia pages.

    Dr. Wade will keep writing her articles, but she also wants to teach other people how to add articles to Wikipedia. She would like to create a website to keep track of all of the biographies. She wants to turn them into a teaching tool.
