If you had a strange sound in your ear, what would you do? One man in Wales who thought he had a fly in his ear called 999, the emergency services number in Britain. And so did a woman who was worried about her green potatoes. Could she make chips with them? Were they poisonous? She didn't hesitate about calling the local ambulance service to ask. According to a recent report, more than 31,000 non-urgent calls were made to the Welsh Ambulance Service in the last year.

    Inappropriate calls are a headache for health professionals everywhere. In the US, prank calls to 911 happen on a daily basis. Many callers use apps which hide their identity. But those who try to be funny shouldn't be surprised if the police have the last laugh. One man from Colorado was arrested for making more than 1,200 prank calls, according to a report on the US television station KOAA—TV.

    People who take these calls are trained to stay calm and keep a straight face, no matter how strange the call sounds. “There's no way for us to know whether the call is real, accidental or a prank call,” said a public safety worker interviewed by the American TV channel.

    The Head of Clinical Services at the Welsh Ambulance Service, Richard Lee, has a warning for prank callers. He says:“ When people misuse the service it means our precious time is being taken away from someone who really does need our help.” Indeed, these hotlines are supposed to help the seriously ill or those with a life-threatening injury. You never know, one day, the person who needs assistance could be you or someone in your family.

    When he was driving home one evening on a country road, Joe saw an old lady, stranded（抛锚）on the side of the road. He stopped in front of her car and got out. Even with the smile on his face, she was worried. He looked poor and hungry. He knew how she felt. He said, “I am here to help you, madam. Why don't you wait in the car where it's warm? By the way, my name is Joe.”

    She had a flat tire（轮胎）.Joe crawled under the car, changed the tire. But he got dirty and his hands hurt. She could not thank him enough and asked him how much she owed him. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance he needed, and Joe added, “And think of me.”

    She drove off. A few miles down the road the lady saw a small restaurant. She went in. The waitress had a sweet smile, and was nearly eight months pregnant（怀孕）. The old lady wondered how someone like her who seemed poor could be so kind to a stranger. Then she remembered Joe. After the lady finished her meal, the waitress went to get her change from a hundred-dollar bill. But she stepped right out of the door.

    When the waitress came back, she noticed something written on a napkin, “I am helping you because someone once helped me. If you really want to pay me back, here's what you do—Do not let the chain of love end with you.”

    That night when she got home, she was thinking about the money and what the lady had written. She and her husband needed money with the baby due next month. She knew how worried her husband was, and as he lay sleeping next to her, she whispered, “Everything's going to be all right. I love you, Joe.”

    Many experts say that Billy Wilder changed the history of American movies. He is often called the best movie maker Hollywood has ever had, known for making movies that offered sharp social comment.

    Between the 1930s and the 1980s, Billy Wilder made almost fifty movies. During that time he received more than twenty nominations from the Academy of Motion Picture Arts and Sciences. He won six of the Oscar awards. His movies have been seen by people around the world, like “Sunset Boulevard”, “Some Like It Hot”, “The Lost Weekend”, “The Apartment”, and “The Seven Year Itch”.

    Samuel Wilder was born in 1906 in the former Austro-Hungarian Empire. His mother had enjoyed spending several years in the United States when she was young. So she called him Billy because she thought it sounded American. Billy Wilder started law school in Vienna, Austria. Then he decided not to become a lawyer. Instead, he began reporting for a Vienna newspaper. By the 1920s, he was writing movies in Germany.

    However, the Nazis had risen to power in the nation. Wilder was Jewish, and he recognized that he had no future in Nazi Germany. In 1933, he went to Paris. There he directed a movie for the first time. It was called “The Bad Seed”. Then he received word that producers in the United States had accepted one of his scripts. Billy Wilder left Europe for America.

    Billy Wilder had only eleven dollars when he arrived to settle in the United States in 1934. He decided to live in the center of American movie making, Hollywood, California. Then he formed a writing team with Charles Brackett. The two writers created many successful films together. Wilder always praised this man as a friend and teacher whose humor and expert direction greatly influenced his work.

    In his love stories, Billy Wilder did not follow the Hollywood tradition of sweet boy-meets-girl situations. He had an unusual way of showing relations between men and women. Wilder died in March, 2002. A current Hollywood producer said: “Billy Wilder made movies that people will never forget.”

    Those accustomed to browsing (浏览) through thousands of books in large bookstores may find Japan's Morioka Shoten a little strange. That's because this tiny bookstore that is located in Ginza, Tokyo sells only a single book at a time.

    Opened in May 2015, Morioka Shoten is the brainchild (脑力劳动成果；发明；主意) of Yoshiyuki Morioka. He began his career as a bookstore clerk in Tokyo's Kanda district before branching out into opening his own store. It was here while organizing book reading and signing that he realized that customers usually came into the store with one title in mind. Morioka began to wonder if a store could exist by selling multiple copies of just one single book. In November 2014, he partnered Masamichi Toyama to establish a unique bookstore with the philosophy of "a single room with a single book".

    The selections that are picked by Morioka change weekly and vary widely to attract customers with different interests. Recent choices include The True Deceiver, an award-winning Swedish novel by Tove Jansson, Hans Andersen's fairy tales, and a collection of Karl Blossfeldt's photography of plants. Morioka has also selected books written by a famous Japanese author Mimei Ogawa.

    To highlight his only offering, Morioka often uses clever tricks. For example, when selling a book about flowers, the storekeeper decorates his shop with the ones that have been mentioned in the book. He also encourages authors to hold talks and discussions so they can connect with customers. Morioka says his goal is to let customers experience being inside a book, not just a bookstore.

    Risky as the idea might seem, things appear to be going well. The storekeeper says he has sold over 2,100 books. Things can get better given that his bookstore is becoming increasingly popular not just among the locals but also visitors from other countries.

    It was hard to accept, but the sad day had finally arrived. I still remember the tears welling up in my six-year-old sister's eyes as she looked around the empty closet in wonder. The space once filled with her clothes now held only loneliness and sorrow. This little child had come to the realization that her father was gone. He had left us, and there was simply no way to change it.

    Being the oldest of four girls has never been easy, but with the departure of our father, our world and dreams were broken beyond repair. My mother, the most amazingly warm-hearted person in the world, has worked harder than anyone should simply to mend our broken household. However, long hours at work often prevented her from physically being there in our times of need. This is where I have stepped up as the temporary caretaker of my three small sisters.

    Many students write college essays about their leadership positions in school and the community but I feel that my greatest accomplishment is the role I have played within my own family.

    Senior year in high school is not simple for anyone, especially when it feels like the entire world is resting on your shoulders, but this is how I have felt for the past two years, I have continually tried to fulfill the dream my mother holds for my future. My mother was not able to complete her college education, and so this success is her top significance for her children.

    A leader is defined as one who has influence on others. I hope that my leadership affects the lives of my sisters and everyone around me. In dedicating myself to my family and school, I have set goals that I will do anything to accomplish. I am an extremely determined individual, and my university will help me take the next step in climbing the ladder of success.

As summer approaches, many kids and teenagers may find that they have more time in hand. One great way to make use of the extra time is to go on an adventure and travel. Clearly, I am not a naturally adventurous person, but I have found that taking the risk and challenging myself to explore and travel to unfamiliar places can be a very rewarding experience.

Because I am usually quite busy during the school year, most of my travels take place during the summer. Over the past few summers, I have hiked in the Grand Canyon, explored Niagara Falls, and camped out in upstate New York. Although these experiences are varied, they are similar in that they instil （逐渐灌输 ）a sense of appreciation for nature and a more balanced view on life. When I hiked in the Grand Canyon, for example, I was in awe （敬畏） of the geological influences that shaped the canyon.

Adventures, of course, are not limited to hiking. There are many other choices, such as camping, volunteering in a foreign environment and travelling to different countries. In my opinion, adventures are more enjoyable with family or a few friends. There is a sense of bonding that one only gets through spending time together in outdoor adventures. For example, when I was in Boy Scouts, I often went on weekend camping trips with my friends. When I came back from a Boy Scouts camping trip, I often was eager to go outside more and explore the parks and nature around me.

Next fall, I will attend college. In the meantime though, I hope to make the most of my summer to explore and travel. Now, I am planning on hiking and camping out in Maine.

When I visited Maine last fall, I was amazed by how beautiful it was and the tall trees and coasts that exist, and I really hope to enjoy the beauty of nature there this summer.
