4 次の英文は、中学生の彩音 (Ayane)が、アメリカ滞在中のホストファミリーであるスミ ス夫妻 (Mr. and Mrs. Smith)の親戚であるベルギー(Belgium)出身の大学生 (university student) のエレン (Ellen) と交流した話です。 1~7の問いに答えなさい。 I've lived here since Ayane stayed in the United States this summer to study English. First, she lived only with Mr. and Mrs. Smith. A week later, Mr. Smith said, "I came to work in the United States from Belgium about twenty years ago. then, but some of my family still live in Belgium. 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. She started studying at the university to run her own business in the future. She was very kind. Ayane and Ellen often went out together on weekends. ア Before the movie, 10 One day, Ayane and Ellen went to see a movie. they went to a shop to buy something to eat. 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.
