Reading English textbooks for high-school students

When I was young, most of the students in Japan started learning English at the age of twelve. I should have kept the textbooks that I used in junior-high school and high school, but I threw them away. When I was about forty years old, I followed Masao Kunihiro's advice "Repeating Reading aloud(只管朗読)"; I got English textbooks for high-school students that were used as authorized textbooks in Japanese schools. The title of the books I bought was "The Crown English Series."

In book II, which is, I suppose, written for sixteen-year-old students, you can read passages from "I Believe" by Bertrand Russell, some from "Momo" by Michael Ende, some from "Japanese and Americans" by Edward Seidensticker, etc.
