.... Reading Comprehension II 次の文章を読み、 後の問いに答えなさい。 Rakugo is a form of traditional Japanese spoken entertainment. It first became popular among people of the merchant class "chonin," and also spread to the lower classes during the Edo period. 16 A single rakugo performer appears on stage and kneels on a cushion. The performer wears a traditional Japanese kimono and usually has nothing except two stage properties: a paper fan and a hand towel. The fan can be used to represent a variety of things, such as a pipe, chopsticks, a pen, a fishing pole or a cup. Sometimes it creates sound effects. The hand towel can be used for things like a letter, a book or an actual towel. The comic story, which the performer narrates, is usually in the form of a conversation between two or more characters. The storyteller plays the two or three roles fluently and switches from one character to another by changing his voice, accent, or expression and turning his head, so the audience can imagine the scene. In the Meiji period, a British rakugo performer brought a lot of excitement to the audience. He was the first foreign-born rakugo perfomer, named Henry James Black, who adopted the stage name "Kairakutei Black." Everyone had a good laugh at hearing his comic tales and his fluent Edo dialect. 注 kneel on a cushion 座布団に座る sound effects have a good laugh at 〜 〜 に大笑いする
