Li Ming ,a university professor(教授), is busy doing some research. So he is ofien on business. When he is at the airport or on the train, he especally loves reading e-books. He also likes reading paper books in the library for his research work. Besides, he enjoys the smell of the paper books.
What's, more, Li Ming would like to read wih his family. There is a reading time from 8:00 to 9:00 each Friday evering at home. Everyone reads and shares what they learn from the books. One Friday evening, Grandma took out an old paper book and said to her grandson, "Lei Lei, this is the first book your grandpa gave me. There is his name on the front page. Whenever I read it,I can get something new from his notes. And I can sill remember the happy life we lived together." Li Lei said," But I enjoy rending e-books. E-books need no paper. Many forests will be saved." Grandma advised. " Don't read for a long time, or your eyes will get sore.”
Different people have different ideas about e-books and peper books. No one knows whether e-books can replace(代替)paper books or not. Somehow, books are our friends. No matter which kind of books you choose to read, you can learn more about the world through them.
1．Do all the people prefer reading e-books?
2．When is the reading time in Li Ming's family?
3．What does the old paper book mean to Grandma?
4．Do you think e-books will replace paper books in your life? Why or why not?

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
