回 海外で発行されている日本のガイドブックに、漫画とアニメの記事が掲載されています。 記事を読んで、あとの問いに答えなさい。 People around the world now know and love Japanese anime. Some characters are familiar to people who do not usually read manga or watch anime. One of the reasons for this success is the adjustments that were made for viewers overseas Three of them involve titles, characters, and content. 2 Manga and anime titles are, of course, originally in Japanese. Some, like this does not work with all titles. For example, Knights of the Zodiac is originally Seinto Seiya in Japanese. It describes just the main character, but in English, the title was changed to something that relates to the whole story. This made it more attractive to viewers in foreign countries. Characters' names are often changed in manga and anime that are mainly for children. It is hard for children to remember unfamiliar names. With familiar names, children can focus on the story. For example, the character Satoshi in Pokemon becomes Ash in English. The name Ash uses three letters from S-a-t-o s-h-i. Japanese customs are sometimes adjusted for non-Japanese viewers. The adjustments can be small or large. Consider this example of a small adjustment. In anime in Japan, characters eat onigiri. In Western versions, they eat cookies. In manga, they don't change the pictures. Instead they add short explanations. This way, foreign readers can understand Japanese customs and behavior. A large adjustment might be a change in the setting. Consider Kyojin no Hoshi, an anime from the 1970s. In it, the main character Hyuma trains very hard and becomes a professional baseball player. In the Indian version, its main character plays cricket, a popular team sport in India. In short, perhaps anime became more popular because of these adjustments. The language and customs were adapted a little to fit each culture. Think about your favorite manga or anime. The original is probably different.

の英文の内容に関して (31) から (35)までの質問に対する答えとして最も 4[C] 切なものを 1,2,3,4の中から一つ選び、その番号のマークをぬりつぶしなさい。 Abbie Burgess About 200 years ago, there were no airplanes or trains in the United States, so people used ships to travel. Some areas were very dangerous for ships, so lighthouses* were built in these places. At night, people on ships knew they had to be careful when they saw the light on the top of a lighthouse. The people who took care of lighthouses were called lighthouse keepers, and their job was very important. In 1853, a 14-year-old girl named Abbie Burgess moved to an island in Maine with her family. No other people lived on the island, and Abbie's father was the lighthouse keeper. Abbie helped her father in the lighthouse. She learned how to clean the lights in the lighthouse and do many other things. The lights had to shine* brightly until morning. Just before winter in 1856, Abbie's father had to leave the island to buy food. He had to go 25 miles by boat to get to the nearest town. He told Abbie to take care of their family and the lighthouse. After he left, a big storm came, and it was the biggest storm in 100 years. It rained and snowed for four weeks, so Abbie's father could not return to the island. Abbie took care of the lighthouse by herself for one month. Finally, Abbie's father came back. He was very happy because his family was safe. Abbie did a great job. Her work saved many people's lives. Abbie became the assistant* lighthouse keeper in 1862.
