Unit 4 Astronomy：the science of the stars 【美文阅读】关于大地起源的神话有许多许多，你了解多少呢？The sky and the earth were at first one blurred entity(混沌整体) like an egg. Then Pangu was born into it. The separation of the sky and the earth took eighteen thousand years. The yang which was light and pure rose to become the sky，and the yin which was heavy and murky(黑暗的)sank to form the earth. Between them was Pangu, who went through nine changes every day, his wisdom greater than that of the sky and his ability greater than that of the earth. Every day the sky rose ten feet higher, the earth became ten feet thicker, and Pangu grew ten feet taller. Another eighteen thousand years passed, and there was an extremely high sky, an extremely thick earth, and an extremelytall Pangu. After Pangu died, his head turned into the Five Sacred Mountains(Mount Tai, Mount Heng, Mount Hua, Mount Heng, Mount Song), his eyes turned into the moon and the sun, his blood changed into water in river and sea, his hair into grass. In all, the universe and Pangu combine in one.【诱思导学】1．Do you agree on the forming of the universe？Give your reasons.________________________________________________________________________________________________________________________________________________2．What kind of people is Pangu in your eyes?________________________________________________________________________________________________________________________________________________【答案】 1.No，I don't agree.Because the scientists have already found out how the universe formed.2．I think Pangu is very great and determined.He is a hero.Period ⅠPreviewing(教师用书独具)●教学目标本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，就下一堂课对课文的全面理解起到一个铺垫作用。
