4 次の英文は、中学生の涼太 (Ryota) がある出会いを通して学んだことについて 英語 の授業でスピーチをしたときのものです。 1~6の問いに答えなさい。 I Hi. I'm going to talk about my experience this summer. visited my brother, Takuya, in Tokyo. He has lived there and studied at a college for two years. I took the eleven o'clock An hour later, a foreign Shinkansen for Tokyo on July 26. woman with a big bag came to the seat next to me. She smiled s at me, but I didn't talk to her. She looked at the baggage rack for a while and then sat in her seat. She put her big bag on her lap because she could not put it on the baggage rack. I thought I should help her, but I didn't do anything for her. She was on the Shinkansen for about one hour and got off. About one hour later, I arrived at Tokyo Station. That night, my brother and I talked about the woman on the Shinkansen. I But I said, "I didn't do anything for her because I can't speak English well. know I should help her." He asked me, "Ryota, if a Japanese woman with a I big bag comes to the seat next to you, will you help her?" I said, "Well ..., don't know." He said, “I don't think that you didn't help the woman on the 15 Shinkansen because you can't speak English. We need some courage when we want to be kind to someone. When I was a junior high school student, I also didn't have courage. You need to have courage, Ryota." I said to him, "I see. I'll have courage to be kind to people around me." I thought, "What should I say in English when I want to help someone?" 10 courage : 20 On the return Shinkansen, the foreign woman came to the seat next to me again! She had the big bag again. I thought I should have courage and said, "Excuse me. ()" She said, "Oh, thank you very much." Then I put her bag on the baggage rack and asked her, "Do you remember me? I was next to you on the Shinkansen two days ago." She smiled at me and said, "Wow ! 25 Yes. I remember you. Hello again." I felt very happy and said to her, "I'm Ryota. You could not put your bag on the baggage rack two days ago. I knew that, but I didn't do anything. I'm sorry." She said, "Oh, it's OK. You are kind. I'm Anila, from India. This is my first trip to Japan." Then we talked a lot together. I talked about my family and school life. I 30 was (2) because I could talk in English. That was my first experience for me.
