2次の文章は,カナタに帰国したJudy が Maki に送ったEメールの内容である。 Dear Maki, Thank you for your help during my stay in Japan. Do you remember that you took me to the Dream Festival ? I enjoyed it very much. I enjoyed learning about Japanese culture at the festival. I played the shamisen for the first time at the event "Try new things!" The sound of the shamisen was very new to me. It was a wonderful experience. I learned that it is very important for me to try new things.The shamisen was one new thing. In Canada, I have started to practice the shamisen. Ipractice it every day. e piu The other day, I went to a concert withmy sister, Amy. It was exciting ! Japanese *musical instruments, such as the shakuhachi, shamisen, and wadaiko, were played together with western musical instruments, such as drums and guitars. I was very surprised. When they were played together, music became more beautiful and powerful ! At the end of the concert, I was very happy to have a chance to play the shamisen witha special band on the stage ! That was a lot of fun. I found a new thing I wanted to do. I'm very glad about that. Have you started doing any new things? Ifyou have, tell me about them. I'm looking forward to hearing from you. Yours, Judy [注) musical instrument 楽器 western 西洋の powerful 力強い sheのふセでけどれか。
