Reading can only be fun if you expect it to be. If you concentrate (集中) on books somebody tells you " you ought" to read, you probably won’t have fun. But if you put down a book you don’t like and try another till you find one that means something to you, and then relax with it, you will almost certainly have a good time -- and if you become, as a result of reading, better, wiser, kinder, or more gentle, you won’t have suffered during the process.
