◆次の英文を読んで,あとの問いに答えなさい。 <埼玉改〉 Ayako is a junior high school student and her homeroom teacher is Mr. Tanaka. He said to the students in class, "You will have work experience next month. So think about the future and the work experience you want. Then talk about these with your family. This is your homework. Next Monday you are going to talk about it with your classmates in class." That evening Ayako talked to her family about the homework. She said, "I have no idea about the future. What should I do?" Her mother said, "You don't need to worry about it now." Her brother said, "When I was a junior high school student, I was like you. But I was interested in environmental science when I was a third year student in high school. Now I'm studying it at college." Her father asked, "What are you interested in?" Ayako couldn't answer. He continued, "You should think about that first." Next Monday when class started, Mr. Tanaka said to the students, "Talk to the person next to you about the future and work experience. Then give some advice to each other." The person next to Ayako was Robert. He was from Australia. They enjoyed playing basketball at school and were good friends. "Well, Robert, do you have any ideas about the future and work experience?" Ayako asked. "Yes. I want to go to a hospital for work experience. When I was sick in the hospital, a nurse tried hard to help me in English. And she took good care of me. I was very glad. So I want to be a nurse in the future and help people," he said. "How about you, Ayako?" "I have no idea about the future," she said, and then talked to him about her father's advice. "Your father's advice sounds good," he said. "OK. I'll ask you some questions. What do you like 20 to do?" "I like to play basketball on the school's basketball team," she answered. "I like basketball too. Why are you interested in it?" he asked. "Because it's fun to play. And I'm the captain of my team, so I teach basketball to the younger members. I'm interested in that," she answered. "I think you are good at teaching basketball, and all the members like you," he said. "Oh, thank you," she said. "Well, Ayako, how about a school teacher as a future job?" he said. "I think you will take good care of students." 1 35 1. 25 "Thank you. I think it is an important job. OK. I'll think about it," she said. At the end of class 30 she was happy because she had an idea for her future job. She thought listening to her father's advice and talking with Robert were useful. The next week Ayako and Robert were talking again. He said, "Well, Ayako, did you think about work experience? Where do you want to go for it?" Ayako smiled and said, "I'm thinking about teaching at school as a future job, so I want to go to an elementary school for work experience. If I 35 work as a teacher, I need to learn a lot of things. I'm studying harder now."
