Preface, conclusion and speech of the twelve constellations

I made a ppt about the twelve constellations, but there was no preface, no ending and no speech! I'm a lecturer! You can let me refer to it so that I can give my opinion! Author: Luo Ji, Director of Academic Research Department of Taipei Yi Society, Preface = People live in the cradle of the vast sky! The stars accompany you and me day and night! We are enjoying its elegance! It gives us the energy of life! Let's enjoy the bright sunshine and sky! We humans have not thanked it yet! But we must understand and cherish it! Because if we lose the sun, the moon and the planets! Humans will also lose their lives! Let's touch those stars hand in hand! Moon! The sun! Constellation! I personally appreciate your good work!
