F: Hello. T'm Lisa. I'd like to introduce myself. I'm a student from America. I just arrived in Japan a few days ago. I was born and raised in New York. This is my first time to leave my home country, so I'm a little nervous. My father is from Germany and my mother is from India. They both graduated from a university in London. Then they moved to America and got married. My parents have told me a lot of stories about their cultures. Because of their stories, I became very interested in foreign cultures, especially languages and food. My father taught me German, so I use both English and German at home. Also, I started studying Japanese when I was eleven years old. At that time, I was a big fan of Japanese anime. I have studied Japanese for five years. It's not easy, but I'm enjoying it. Ill try to speak to all of you in Japanese. My mother is such a good cook! One of my friends who lived in Japan before gavemy mother a Japanese cookbook, and now she is interested in cooking Japanese food. I have been to a restaurant and eaten some Japanese food, such as sushi, in New York. During my stay in Japan, I'd love to try many kinds of Japanese food, and I also want to learn how to cook it. If you are good at cooking, please teach me! I'm looking forward to experiencing many things in Japan. Nice to meet you all!

2 次の対話文を読み, 設問(a)~(e)にもっとも適切なものを1~4の中から1つ 選びなさい。 Two friends standing in line at a store checkout. Marissa: I know I have it in here somewhere Karen: What are you looking for? Marissa: My point card. Sheesh, I have so many of them now. I can never find the one I'm looking for. Karen: I know! It's getting ridiculous, isn't it? Every store has its own, and they're all different. Hold on a second. Let me go look by the register. They usually have a sample Yeah, the one for this store is orange. Marissa: Orange? Oh, here it is. Thanks. I really wish there were a better system. Pretty soon I'll need to start carrying a second wallet. Crazy! Karen: You know what would be great? If we had just one card that we could use for every store. You know, with an IC chip in it. I think those chips can hold a lot of data. It could hold point information for every store you go to. Marissa: That's an interesting idea but wouldn't it be a little risky? What if you lost it? You'd lose the points from all your stores. And Karen: Actually, I think most point data is now stored online. anyway, if you keep all your cards in the same wallet, what's the difference? What happens if you lose your wallet now? Marissa: Yeah, I see your point, I guess. But after all, I don't mind that each store has its own point card, because I like looking through the different designs. It's almost like collecting trading cards. Karen: Then you'll definitely need that second wallet! 5 英LAEEJPKS-006
