My brother's daughter will come from Belgium to live here. Her name is Ellen, and she will go to university s here. I hope you will be good friends." Soon after that, Ellen came.

Ellen bought a hamburger and some French fries. Ayane said, "Do you know that ( 2 )? It's 'fried potatoes." Ellen was surprised. She asked Ayane, "Where did French fries originally come from?" Many people think they are from the United States. Ayane thought they came from France because the name is "French" fries. So she answered, “France !” 15 That was wrong. Ellen said that French fries were originally from Belgium. Ayane was surprised. Ellen said, "When American soldiers went to Europe in World War I, they ate frites. Frites are popular food in Belgium. They're like French fries. The American soldiers liked them. The people in the area spoke French at that time, so the soldiers thought the area was in France. Later the 20 soldiers brought the food to the United States. So the name became French fries." That was an interesting story to Ayane. She didn't know that people speak French in some areas of Belgium. Ellen also can speak French. Ayane was surprised again. Then Ayane bought some waffles at the shop because she heard they were 25 very good. Ayane said, "Waffles are also originally from your country, right?" Ellen answered, "Yes. I've liked them since I was a child." Ayane heard that Ellen's dream is to run waffle shops in many countries. She hopes waffles will spread into more countries, so she is studying business at the university. Ayane said, "These waffles are nice! I like waffles, too. When you start your 30 waffle shop in Japan, can I help you at the shop?" Ellen answered, "Yes. Oh, the movie will start soon. Let's go, Ayane!" "Yes, let's go," Ayane said. Ayane was happy because she understood Ellen and her country better.

t forced to commit suicide in the closing days of World War II, police have said. The boys, between the ages of 16 and 19, have said that they destroyed two *signboards and origami paper cranes left by visitors to the Chibichirigama cave between Sept. 5 and last Tuesday, police said Friday. 着 During the *Battle of Okinawa, which started on April 1, 1945, with the landing of the U.S. *army on the island, more than 80 Okinawa people were believed to commit suicide in the cave after taking *refuge there. Similar cases of suicide took place at other places during the battle. Family members of those people who killed themselves at the site during the war discovered the damage last Tuesday and reported it to police. Norio Yonaha, 63, who lost five members of his family in the suicide, told reporters that this was “an *insult to the people who died" there. Bottles and vases left behind by the dead people were also damaged.

3 次の英文は, 南中学校に通う瑠美 (Rumi) が学生ダンス競技会 (the Students' Dance 'Competition) について, 得点の表 (Table) を作り, 英語の授業で発表したときのものです。 1~3の問いに答えなさい。 I'm on the school dance team. We had the Students' Dance Competition last Saturday, and eight dance teams from the junior high schools and high schools in our city performed. We didn't think we could win the dance competition, but we came in third overall. Please look at this table. It shows the scores of the top three dance teams. Igawa High School got the best score of the three teams for 5 dance technique, but they came in second overall. They danced very well, but they didn't smile enough. They needed more expression. In contrast, Heisei High School didn't get a high score for dance technique, but they got 86 points for dance expression. They were dancing with smiles. I enjoyed their dancing. To my surprise, we got better score than Heisei High School for dance expression. We started practicing for the dance competition two months ago. We practiced after school and on weekends to win the dance competition. We enjoyed dancing at first, but a month ago, we didn't enjoy it. When we were dancing, our English teacher, Mr. White, came to us and said, “Enjoy dancing! Relax more and dance with smiles. When ( ① ), the audience doesn't enjoy your 15 | dancing.' We found we didn't enjoy dancing. We practiced only to win the competition, and we forgot the most important thing. On the day of the dance competition, we danced with big smiles and got a good result. I will enjoy everything with a smile.

芯のですが I would say that it was about fifteen years ago, a little girl, perhaps ten years old, was sitting in a wheelchair outside the hospital of Maputo, the capital of 1 Mozambique. To my surprise, the girl had no legs. I had a few words with her. She spoke in a very low voice, and 私は彼女に話しかけた it was difficult to catch what she was saying. But I understood that her name was Lilia. Today, many years later, Lilia is one of my closest and dearest friends. No one has taught me as much as she has about the conditions of being human.
