Unit 4 Astronomy the science of the stars话题导入Astronomy is the oldest science known to man.Thousands of years ago man looked at the stars and wondered about the heavens.But man was limited by what he could see with his eyes alone.The Greeks studied astronomy over 2,000 years ago.They could see the size，color，and brightness of the stars.They could see their places in the sky.They watched the stars move as the seasons changed.But the Greeks had no tools to help them study the starry heavens.Each new tool added to the field of astronomy，it helped man reach out into space.Until there were telescopes(望远镜)，man knew little about the moon.They did not know that the planet called Saturn(土星) had rings around it.Their sight was so limited that they could not see all the planets.In the early 1700s，peoplethought there were only six planets.Before the spectroscope(分光镜)appeared，man did not know what kind of gases is in the sun or other stars.Without the radio telescope(电望远镜) we did not know that radio noises come from far out in space.Today，astronomy is a growing science.We have learned more in the last fifty years than in the whole history of astronomy.根据上文完成下列各题1．The oldest science known to man is astronomy.2．What does the underlined word “it”(Line 5，Paragraph 3) probably refer to？(1 word)Saturn.3．What does the passage mainly tell us?Science can’t grow fast without modern technology.Period One Warming Up & ReadingⅠ.单词1．v.multiply乘；增加exist存在；生存puzzle(使)迷惑；(使)为难2．n.astronomy天文学system系统religion宗教theory理论；学说atom原子billion万亿；十亿globe球体；地球仪carbon碳atmosphere大气层；气氛chain链子；连锁oxygen氧3．adj.violent猛烈的，激烈的fundamental基本的；基础的harmful有害的Ⅱ.短语1．及时；终于in time2．下蛋lay eggs3．产生；分娩give birth to4．轮到某人；接着in one’s turn5．阻止，制止prevent...from1．No one knows exactly how the earth began，as it happened so long ago.没有人确切知道地球是怎样形成的，因为在很早以前它就形成了。
2．The earth became so violent that it was not clear whether the shape would last or not.地球变得激烈动荡，不知道这个固体形状是否会继续存在下去。
3．It was not immediately obvious that water was to be fundamental to the development of life.水对生命的发展会起关键作用，这一点在当时并不明显。
4．What many scientists believe is that the continued presence of water allowed theearth to dissolve harmful gases and acids into the oceans and seas.很多科学家相信，由于地球上长期有水存在，使地球得以把有害气体和酸性物质溶解在海洋里。
5．They are putting too much carbon dioxide into the atmosphere，which prevents heat from escaping from the earth into space.他们把过多的二氧化碳释放到大气层中，这使得地球上的热不能释放到太空中去。
6．So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.所以，在未来的数百万年中，生命能否在地球上延续取决于这个问题能否得到解决。

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。
