CUTTING EDGE 1-05 絶滅危惧種の選定 Have you ever heard of the "quagga"? Perhaps not, but you may have seen a zebra before. (1)The zebra is a horse-like animal with 形M distinctive black and white stripes covering its body. The quagga was a member of the zebra family, brownish in colour with white stripes FOS around the neck and the front part of the body. (2)It is often said that quagga looked like "zebra which had forgotten to put on their pajama trousers." Quaggas lived in Southern Africa, but they died out in the 19th century due to overhunting. We can now only see their wild beauty as 3stuffed specimens. Some researchers, however, have tried to "revive" the quagga. Because of its attractive stripe pattern, the quagga has gathered much attention from those interested in animal conservation. Those who would like to see the animals walk around the savannas again have conducted the Quagga Project for over thirty years in South Africa. Fas 模様のない (3)It turns out that the quagga is genetically close to the plains zebra. In this project, researchers have attempted to selectively breed plains zebras: they chose plains zebras which have fewer stripes and look slightly like quaggas. Baby zebras born to a slightly quagga- like mother and father may look more like the quagga, with a 13 significantly reduced number of stripes. (4)This project has achieved a certain level of success, producing several lovely baby zebras which have striking similarities [to ] the quagga. . However, should we be happy about this? (5)While this new generation of zebras is visually impressive, it only resembles [X]

これの（②）に一語を文章から抜き出していれるんですけど、quickはだめですか？ 答えはearlyでした。

When I first moved to Japan, my new life was like an adventure, and full of surprises. Ive forgotten a lot of small things, but I'll never forget the first party I gave. 1was teaching English at a university in Japan. I decided to have a party for some Japanese students at my apartment which was near the school. The party was at 7:00. I was rushing to get ready, cleaning the room, checking the food, and so on. And finally at about 6:45, I was about to take a quick shower and get dressed. Perfect timing, I thought. But just then, the doorbell rang. The students, in one big group, were already at my door! In America nobody comes early, and in fact, most people come a little late on purpose, usually alone or in pairs. We call Oit being “fashionably late." I had to ask them to wait outside for about 15 minutes. “The party starts at 7:00!" I said, This was a real life lesson for them and for me about cultural differences. They learned they should not come to my parties ( ② ) again, and I learned I should be ready a little (2 )just.in.case. So at 7:00, everyone came in, with my second surprise. ③They showered me with all kinds of presents! I was happy to get so many presents, of course, but I really didn' t want them to come together. I was very busy because I had to find vases for the flowers, bowls for the snacks, and try to say Thank you' for their gifts. People usually take something likea bottle of wine to an American-style party. But I felt. more. appreciated by my_guests in Japan. It was more like my birthday or Christmas than a simple homeparty. FinallyI sat on the sofa and talked with them. Everyone was having a good time. Though I have lived in Japan for more than ten years, I m still surprised at many things. Life is full of surprises.
