There is a story that happened in a library. A student found a very (use) book in a bookstore, but the book was too expensive for him (buy). So he decided to read the book in the library. Every afternoon, the student would go to the library to read a little at a time. One day he couldn't find the book from its usual place. Just then he heard the librarian calling him. To his surprise, the librarian pointed to （指向） the book in a corner and said, "I put it there that it won't be borrowed." The student was touched by the (warm) of the librarian.
