読解力をつけよう 516 Words 目標6分 ◆次の英文は、高校生の次郎(Jiro) さんが、 英語の授業中に自分の祖父(grandfather)について発表したもので す。これを読んで、 あとの間いに答えなさい。 My grandfather is great. I'm going to talk about him. He always tries to study new things. After retiring from his job, he has studied sign language, calligraphy and so on. Now he is studying how to use computers. He also studies English hard. He likes studying very much. First, I'll tell you about him and computers. There was already one computer in my house, We used it to do many things. But my grandfather never tried to use it. One day I got a ticket for a trip 5 for him on the computer. He said, “Thanks. I'm surprised. It is very easy to get a ticket on the R (徳島改) computer!" I said, "Yes, it is." A few weeks later, I was using the computer to make my report with some pictures. My grandfather came to me, and said, “You have made your report with pictures. It is very good and beautiful." OHe became interested in computers. 10 He started to study how to use computers in a class for senior citizens, and bought some books about computers. He also bought a new computer. He enjoyed the class, and he studied for about two hours every day. When he first began to study, he couldn't use computers well, so he asked me many questions. Now he can use computers better than me and enjoys using them. He can get tickets for his trips or look for good hospitals on the Internet. On the computer, he can make leaflets with pictures and is also going to make a web page for the senior citizens group in his town. When he showed the leaflet he made to the members of the group, 15 they said, “You've made it! It is very wonderful and beautiful." He was very happy to hear that. My grandfather said to me, “I'm going to make a web page for the group. I want to study more about computers to make a good web page. When we learn more, we can do more.” Now he is trying to 20 make it. Next, I want to tell you about (2my grandfather and English. He traveled to Canada with his friends last year. When he came back, he showed me many pictures of Canada, and said, “I enjoyed visiting many beautiful places. When I went shopping, I tried to use English. It was difficult for me to speak English, but I tried it. I was very happy because the clerk understood me. If I can speak English 25 better, I can enjoy the trip more. I've decided to study English every day.” He studies English very hard. He repeats English words and sentences he has learned from books and CDs. He said, “This is a good way for me to study English. I want to go to many countries and talk with people in English." He said, “I like and enjoy studying new things because I can get different ideas and new information. 30 That makes my life fruitful. It is interesting for me to study.” I think his words are true. I want to enjoy studying new things as he does. | retire (retiring) 退職する senior citizen (s) 高齢の人 sign language 手話 calligraphy 書道 report レポート leaflet(s) ちらし web page ホームページ clerk 店員 sentence(s) 文 fruitful 実り多い

It shows some kinds of kitchen garbaca people throw away at home, and they are the things people didn't have to throw awar Look, we can see it on my phone here. Kate: I heard that people cut and throw away too manyparts of food when they cook. Ryo : Yes. About eighteen *percent of the kitchen garbage in the graph shows that. Kate: What does the biggest number mean? Ryo : It means that about thirty-six percent of the kitchen garbage is food which was not used. I see. Why does such a thing happen? Look at this table. I also found it on the same website. People in the town answer Kate: Ryo: the question about their reasons for food waste, and you can see some of them in the table. Kate: More than fifty percent of the people say the same reason for it, right? What is it? Ryo : They say that they throw away food when it has *gone bad. And I want you to look at this. Kate: Do you mean this, about seventeen percent? What is their reason? Ryo : They say that they buy too much food to eat. For example, if they buy too mich and can't use it all for cooking, it may go bad. Then, it will become waste. Kate: Now I'm sure that we should stop buying too much food. Buying by weight is a good way for that. We can buy only the amount of food that we need. Ryo: Iagree with you. But in Japan, we don't usually buy food in such a way. So. we ho to find another way. Do you have any ideas?
