They introduce us the best c [humanity]. They are d [reliable] records of the history. A book is a e [valuable] living voice. We can know about the thoughts and f [rituals] of past men through books. We should read good books and avoid g [worthless] ones. A good book is a friend of h [loneliness] and a nurse in i [ailment]. We can find real j [happiness] by reading good books.
