Then books are sometimes given to you as presents by your parents or friends, I think. Besides (除此之外), if you like reading and want to learn 3 . I am sure that you buy books 4 .

Different people read many times before it is finished. Millions of books are printed (印刷) in our country every year. So people can get 9 to read. Now may I ask you a 10 ? How well do you take 11 of books? What have you learned about the care of books? Perhaps you bought yourselves some 12 books. Do you put paper on them? Do you open 13 ? Sometimes new books break (破) along the back if you open 14 suddenly in the middle. I hope that you don't 15 the pages carelessly. If you do, you may tear (撕) them. | ||||
