【答案解析】I want to return to the era when life was very simple. Then, what you knew were just colors, multiplication table and nursery rhymes, but you didn' t feel you were short of anything--you didn' t know what you didn' t understand, so you wouldn ' t care about it. What you cared about was just happiness, because you were blissfully unconscious of anything worrying and depressing. I would like to think that the world is just and everyone is honest and kind; I would like to believe that any thing is possible.
