Unit 4 Astronomy： the science of the stars Ｉ．单元教学目标II．目标语言III．教材分析与教材重组1。
教材分析本单元以astronomy：the science of the stars, the development of life，space travel and gravity为话题，通过本单元的几篇阅读材料使学生对以上问题有所了解，并通过文章中的一些探讨性的问题，比如，The earth may become too hot for the lives on it. Then what will our future be? 使学生更好地了解我们的地球和我们的生活环境，并引发对“地球的将来如何”的热烈讨论，通过这些讨论激发学生对天文学了解和探究的强烈兴趣。
通过讨论登月球需要的物品和可能遇到的困难学会提出问题和解决问题的表达方法,并能就此写出一篇表达合理思路清晰的短文。
1。
1 WARMING UP以讨论的形式通过三组问题引导学生讨论边缘科学，讨论科学的方法以及要成为真正的科学家所必须掌握的技能。
1。
2 PRE—READING 主要让学生弄清楚什么是科学思想,什么是宗教信仰或文化传统.在探讨生命起源的科学道理之前，让学生以听故事或讲故事的方式，交流有关宇宙的起源的种种传说,既有趣味性，又能调动学生的相关知识，激活学生的思维。
1.3 R EADING 讲述了地球上生命的起源。
水的形成使得地球有别于其他星球，它使得地球上生命的诞生成为可能。
科学家认为，地球上的生命首先诞生于水中，上百万年后，陆地上才长出绿色植物，随后出现了陆栖动物和水陆两栖动物。
最初的动物靠孵化繁衍后代，后来出现了哺乳动物，人类也随之诞生了。
文章最后讲了令人深省的问题：The earth may become too hot for the lives on it。

Unit 4Astronomy: the science of the stars天文学(Astronomy)是研究宇宙空间天体、宇宙的结构和发展的学科。
内容包括天体的构造、性质和运行规律等。
天文学是一门古老的科学，自有人类文明史以来，天文学就有重要的地位。
主要通过观测天体发射到地球的辐射，发现并测量它们的位置、探索它们的运动规律、研究它们的物理性质、化学组成、内部结构、能量来源及其演化规律。
在天文学悠久的历史中，随着研究方法的改进及发展，先后创立了天体测量学、天体力学和天体物理学。
天文学的研究对于我们的生活有很大的实际意义，对于人类的自然观有很大的影响。
古代的天文学家通过观测太阳、月球和其他一些天体及天象，确定了时间、方向和历法。
这也是天体测量学的开端。
如果从人类观测天体，记录天象算起，天文学的历史至少已经有五六千年了。
天文学在人类早期的文明史中，占有非常重要的地位。
埃及的金字塔、欧洲的巨石阵都是很著名的史前天文遗址。
美国著名的女天文学家南西·格蕾丝·罗曼从小痴迷于太空学，被称为“哈勃太空望远镜之母”。
A Great Woman ScientistBack in the 1950s few women in the United States worked outside of the home, and even fewer earned doctorates(博士学位) or went on to have professional careers. However, as the first chief of astronomy at the US space agency, Nancy Grace Roman is a notable exception(例外). She says, “Certainly by the time I was in seventh grade, I knew I had to have a long education if I wanted to become an astronomer.” Pursuing(追求) her interest in astronomy was not easy. But Roman was determined to become an astronomer and learn everything she could about stars. She went to college, studied science and earned her doctorate in astronomy from the University of Chicago in 1949. She has been working very hard and NASA's current chiefastronomer calls her “the mother of the Hubble Space Telescope.” After retiring from NASA in 1979, Roman spends much of her time consulting, teaching and lecturing across the country. Roman hopes she's inspired young women to set aside their inhibitions and reach for the stars, just as she did.根据上文判断正(T)、误(F)1．Many women in the USA worked in the companies in the 1950s.()2．It is not difficult for Roman to achieve her goal.()3．When Roman was very young, she was interested in astronomy.()4．Roman had been teaching astronomy in the University of Chicago until 1979.()5．What Roman did inspires young women to make their dreamscome true.()[答案] 1.F 2.F 3.T 4.F 5.TPart ⅠWarming up, Pre－reading, Reading & ComprehendingⅠ.重点单词1．____________ n．学说；理论2．____________ n．系统；体系；制度3．____________ n．天文学4．____________ n．原子5．____________ v i. & v t.乘；增加6．____________ n．大气层；气氛7．____________ adj.基本的；基础的8．____________ n．球体；地球仪；地球9．____________ n．氧[答案] 1.theory 2.system 3.astronomy 4.atom 5.multiply 6.atmosphere7.fundamental8.globe9.oxygenⅡ.词汇拓展1．____________ v t.使迷惑→____________ adj.迷惑的→____________ adj.令人迷惑的2．____________ adj.猛烈的；激烈的；强暴的→____________ n．暴力→____________ ad v.暴力地；猛烈地3．____________ adj.有害的→____________ n．&v.伤害→____________ adj.无害的4．____________ v i.存在；生存→____________ n．存在；生存5．____________ prep.与……不同；不像→____________ v t.喜欢prep.像；如同→____________ adj.可能的6．____________ n．宗教；宗教信仰→____________ adj.宗教的；宗教信仰的[答案] 1.puzzle; puzzled; puzzling 2.violent；violence; violently 3.harmful; harm; harmless4．exist; existence 5.unlike; like; likely 6.religion; religiousⅢ.重点短语1．根据________________2．及时；终于________________3．冷却下来；变凉________________4．下蛋________________5．产生；分娩________________6．in one's turn ________________7．prevent... from... ________________8．as well as ________________9．in all directions ________________10．depend on ________________[答案] 1.according to 2.in time 3.cool down y eggs 5.give birth to 6.轮到某人；接着7.阻止；制止8．也；还9.朝四面八方10.取决于；依靠Ⅳ.重点句式1．so... that...“如此……以至于……”The earth became ________________ it was not clear whether the shape would last or not.地球(开始)变得如此激烈动荡，以至于不知道这个固体形状是否会继续存在下去。

What struck me was that they have all suffered a lot.给我很深印象的是他们都受过很多苦。
二、主语从句与形式主语it有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。
这分三种情况：(1)对于以连词tha t引导的主语从句，通常用形式主语代主语从句：It’s a pity that he didn’t c ome.很遗憾他没来。
It is important that he should know about this. 他必须知道此事。
It’s vital that we be present. 我们出席是至关重要的。

What I want to know is this. 我想知道的就是这一点。
有时也可将助用形式主语。
如：It is clear enough what he meant. 他是什么意思很清楚。
(4)如果句子是疑问句，则必须用带形式主语it的结构：Is it true that he is the girl’s father? 他是那女孩的父亲，是真的吗?How is it that you are late again? 你怎么又迟到了?三、连词tha t的省略问题引导主语从句的连词that 有时可省，有时不能省，其原则是：若that引导的主语从句直接位于句首，则that不能省略;若that引导的主语从句位于句末，而在句首使用了形式主语it，则that 可以省略：That you didn’t go to the talk was a pity. 很遗憾你没去听报告。
(that不可省)It was a pity (that) you didn’t go to the talk. 很遗憾你没去听报告。
