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
