3 次の英文を読んで、後の各問に答えよ。 Hiroshi is a junior high school student. One day in an English class, his teacher said, "We have many kinds of new technology around us. Computers, the Internet, and AI are good examples. Do you know any people who use them well? In our next project, I want you to introduce one person in class." So at home that night, Hiroshi asked his mother, and she said to him, "Your grandmother, Toshiko, uses new technology well." A few days later, Hiroshi talked with Toshiko on the Internet about the project. She said, "Well, you know I am a fruit farmer. I didn't use technology very much in the past. But now, I use it every day. There are many benefits of using new technology. I collect information about the weather from websites. I can understand my fruit's growth by keeping records and can share that information with researchers and farmers who live in other parts of Japan. Then I can get good ideas from them and make my fruit bigger and better. Now I don't need to give water to my fruit trees because AI technology can do 2 that job. Also, it is easy for me to sell more fruit by using the Internet. In these ways, new technology has changed my way of working and made it better. On my website, I show other farmers how to use new technology which helps us grow better fruit." Hiroshi decided to talk about her to his classmates. A month later, Hiroshi made a speech in front of his classmates. After the speech, his classmate, Asuka, said, “In your speech, I like the story of your grandmother's website. She shows her ideas about using new technology for agriculture. I hope people will be interested in her website. If they see it, they will learn her ways to grow fruit. Then, they will be influenced by her and start working like her. I really respect her." Hiroshi was very happy to hear that. He said to Asuka, "Using new technology in effective ways has been changing the lives of many people. I want to learn about this more and create a better society in the future." 受羽課題 プロジェクト

About 50 years ago, I lived in Los Angeles, California. My father took care of my younger sister and me. We played baseball every weekend. My sister and I loved baseball. I knew that my father had a "hero. His name was Ken Smith. He played for a team in *St. Louis. Its name was the Red Birds. My father said that Ken was the greatest player of all *major league baseball players at that time. I also became a big fan of Ken Smith, so I wanted to be like Ken Smith very much. That summer was special because my father *took my sister and me to St. Louis. We went there and came home by *plane. We were going to meet Ken Smith. I almost couldn't believe that. My father's best friend had a big *company in St. Louis, and he knew some of the very important people of the Red Birds. He also knew Ken Smith well. We stayed at my grandmother's house in St. Louis, She said to me, "Jack, I have something special for you." That was a ball with an *autograph by Smith. An *injured player of the Red Birds was in the hospital, and my grandmother worked there. She told him my story, and he got Smith's autograph on the ball. She knew that A but she gave the ball to me. I was sorry for my father, but I was very happy. I liked Ken Smith more. The next day was an exciting day for us. My father's friend helped us, and we could meet Ken Smith before the game. I thought Smith would be kind and big, and I was right. Then I showed him the ball from my grandmother. We talked about it. He asked me about the way to practice baseball, and I talked to him *proudly. *In front of Ken, I felt that I needed to do so. I wanted to be a great baseball player. He *understood. That night we watched a night game of the Red Birds. During the game, I *held my ball, and looked at it many times. A man talked to me. "New ball?" he asked. "Yes, with an autograph," I said and smiled. "Who?" he asked. "Ken Smith," I said proudly. "Really? I don't believe you." "Here, look." "Wow! I'll get it for 20 *dollars right now!" "No, give my ball back to me, please," I said. "You've got a very special thing. Take good care of it!" he said. I knew that the ball was a *treasure for me. The next day, 3I felt it took a long time to get back to Los Angeles. I was excited and I told my friends about my experience with Ken Smith in St. Louis. No one believed me, but I thought that I would never forget my happy feelings then. About 20 years later, my father died. Before the *funeral, I *remembered that he once *asked us to put his *baseball cards and a *baseball in his *casket. I wanted to use my baseball with Ken's autograph for him. My sister also liked my idea. The ball was with my father. A few years later, my sister *got married. Before *wedding finished, my sister started a story. She was a *flight attendant and *flew with the baseball players of Los Angeles Blue Sky and the manager Tom Baylor. Then she told him the story of my old baseball. He understood her story very well. Baylor was a friend of Ken Smith and *promised her to get another ball with Ken's autograph for me. Ken *was very impressed by her story, and sent a baseball with his autograph to Baylor. The ball was then sent to my sister. When she finished the story, I looked up and saw that she was holding a ball. "I have B threw it to me. I remembered that summer and my grandmother. I felt like a child again when I was going home. she said and
