1.了解演讲者的观点,领悟格物致知精神的内涵。2.梳理演讲者的思路,把握演讲词层层推进的结构。 一、导入新课 1974年,美籍华裔物理学家丁肇中向全世界宣布发现J粒子,开辟了人们认识微观世界的新境界,并因此于1976年获得了诺贝尔物理学奖,成为首位用中文在诺奖颁奖典礼上发表演讲的科学家,引起了世界的轰动。请同学们阅读下面这则材料,了解他取得这项伟大成就的经历。1974年以前,人们认为基本粒子都可以归纳为三种夸克。丁肇中对此持怀疑态度,但他想进行实验的想法却遭到了几乎所有国家大型实验室的反对。最终,他在美国布鲁克海文国家实验室开展了实验,经过两年多夜以继日地实验,终于发现了一种未曾预料过的新的基本粒子——J粒子,而它来自第四夸克。他的发现推翻了过去认为世界只由三种夸克组成的理论,为人类认识微观世界开辟了一个新的境界,被称为“物理学的十一月革命”。丁肇中也因此项发现在1976年获得了诺贝尔物理学奖。
【设计意图】从诗意的语言入手,引导学生关注句式节奏、抒情性、叙事性、哲理性,品析语言,从而加深对文本的理解,体会作者对丽江的热爱、赞美之情,体会作者在景物描写中隐含的思想。五、总结存储1.教师总结作者虚构一个旅游者兼讲述者——“一滴水”,用它形成时空线索,串联起丽江的自然风光、历史文化、民俗风情,并着力表现景物背后的丽江的人文精神,来抒发作者对丽江古城与自然美妙融合的赞美之情,对丽江的醇美、和谐、沉静的赞美之情,对传统与现代文明和谐交融的赞美之情,对自然万物的热爱和生命平等的意识。诗意的语言中,有强烈的抒情,有厚重的历史感,有深邃的哲思。这“一滴水”折射出的,是阿来的思想、灵魂。2.布置作业(1)模仿本文的写法,写一篇不少于600字的随笔,选择一个恰当的视角,跨越时空,全面多角度展现家乡的自然风光、历史文化、风土人情。(2)课外阅读阿来的《大地的阶梯》,体会融景物、历史、感悟、思考于一体的游记风格。
【目标导航】1. 掌握即席发言的要领和表达技巧。2. 通过情境创设的训练,克服发言时的紧张心理,学习即席发言的快速构思方法,提高瞬时应变和即席发言能力。3. 进行即席发言的初步尝试,充分调动课堂参与的热情,培养良好的语言习惯,表现出较高的文化素养和气质风度。【课时安排】1课时自由分成学习小组,做好活动计划,分配小组成员交际任务, 围绕“即席讲话”的这个交际主题,做好本次口语交际。【新课导入】即席讲话,也叫即兴发言,是指在某个特定场合,临时受到邀请,由他人提议或自己认为有必要而作的简短讲话。【交际技巧】即席发言有三个特点:一、临场性即席发言既不能事先拟就讲稿,也不能进行试讲,它必须靠临时准备、临场发挥,因此临场性就成了即席发言最主要的特征。
【深入研读,探究方法】1.思路清晰、缜密。开头紧扣论题,由“格物致知”的出处,引出对其含义的理解以及我国古代并不重视真正的“格物致知”的原因分析,澄清人们的错误认识;接着作者从实验过程的两个特点、中国学生存在的问题和作者自己的亲身经验三个方面分析真正的“格物致知”精神的重要性;最后指出真正的“格物致知”精神的两个意义,并发出号召。全文思路清晰,说理严密。2.举例论证、道理论证和对比论证相结合,论述充分有力。文章在列举事例时,采用正面事例和反面事例相结合的说理方法。如反面事例,文中第4段举了王阳明“格”竹子的事例,证明了中国传统的教育并不重视真正的格物致知;在第11段摆了中国学生大都偏向理论轻视实验的事实;第12段又举了自己到美国念物理时吃的苦头。
第一部分(第1~4段),提出关于6500万年前恐龙灭绝的问题,目前存在的两种对立的理论,即“撞击说”和“火山说”。第2和第3自然段先后举了两个例子提出了关于“撞击说”和“火山说”这两种观点。第二部分(第5段至全文完),通过对“被压扁的沙子”的反思,证明外星撞击导致恐龙灭绝,支持“撞击说”。这部分又分四层。第一层(第5、6段),说明关于恐龙灭绝的原因不仅仅是一个学术问题,我们以后也许还会遇到这种情况,因此,科学家们一直都在努力寻找证据来验证这两种理论。第二层(第7~10段),说明1961年一位苏联科学家发现了“斯石英”,并且介绍了它的性质,为下文佐证“撞击说”奠定了基础。第三层(第11~13段),说明斯石英不仅可以在实验室制造,而且它在自然界中是可以存在的,不过它们只出现在沙子被强烈挤压的地方。由此推断撞击是可以产生斯石英的。事实也证明,火山喷发是不会产生斯石英的,从而进一步佐证了“撞击说”。
【深入研读,探究方法】1.语言优美,通俗易懂,妙笔生花。文章中运用“静穆”“晶莹”“熠熠烁烁”这些优美鲜活的词语,生动形象地描绘了各拉丹冬的千姿百态,壮观奇景,使文章更加的灵动,给人以无限美感。作者以自己的游览经历讲述,语言平实,浅显易懂。2.主题鲜明,意味深长。文章主要讲述作者的一次雪域高原之游,描写了各拉丹冬美丽壮观的景色和作者攀登的经历,给我们以启示:做任何事情要不放弃,不半途而废,勇往直前就能达到自己想要的目标。3.善用比喻,生动形象。文中处处可见比喻的修辞手法,“阳光……巨人” “像长发披肩”都运用了比喻的修辞手法,使各拉丹冬的景色更生动具体,富有感染力,给人以深刻的印象,引发读者的联想和想象。
1.看过了视频,接下来由各个小组与我们分享他们在课下准备的核心价值观小品,每组表演时,剩下的小组猜测表演的是哪一个核心价值观并在活动评价单上进行评分。2.教师总结:“精神文明建设使人们的生活更美好”教师引导学生:精神文明建设搞好了,人心凝聚,精神振奋,各项事业才会全面兴盛。活动二:走进新时代,怀揣中国梦。1.播放“中国梦”优秀少儿演讲视频。2.阅读课本,交流感想。活动三:争做时代好少年1.回顾各小组的表演,把其中所有的不良习惯和闪光举动逐个挑出来再次强调。2.小组交流班级内部常见的坏习惯。教师总结。总结延伸:通过本节课的学习了解到青少儿应积极投身于社会主义精神文明建设的伟大实践中去,做新时代的好少,做新时期中国先进文化的传播者。

(1)这个故事的什么地方最令你感动?(2)你从这个故事中看到邓稼先怎样的奉献精神?1950年,新中国诞生的消息传到了大洋彼岸,年仅 26岁的邓稼先刚刚取得学位,毅然放弃了在美国优越的生活和工作条件,冲破重重阻挠回到祖国。1958年,他接受国家最高机密任务秘密研制原子弹。从此,邓稼先隐姓埋名28年,连家人也不知他的去向,一直奋战在我国西部荒漠中的核基地。在一次航投试验中,原子弹意外摔裂。邓稼先明知危险,却一个人跑上前去亲自察看,导致身体邓稼先受到核辐射的致命伤害。他忘我地工作,和许多著名科学家同心协力,攻破一道又一道科学难关,终于为祖国点燃了那饱含着我国科学家们智慧和力量的神奇之火。1986年7月29日,他临终前留下的话仍是如何在尖端武器方面努力,并叮嘱:“不要让人家把我们落得太远……”4.你还知道哪些为新中国作出贡献的科学家?你能说说他们的故事吗?(1)华罗庚:梁园虽好,非久居之地1950年3 月,来自美国的“克利夫兰总统号”邮轮航抵香港,略作停留,进行补给。
讨论交流:正是靠着这种民族精神,我国建成了一个个大油田。到1965年,中国的石油基本实现自给。5、补充资料1964年10月16日和1967年6月17日,中国西北罗布泊大漠中,升起了蘑菇状的烟云。我国相继成功爆炸了第一颗原子弹和第一颗氢弹,成为继美国、苏联、英国之后第四个同时拥有原子弹和核弹的国家。中国从此拥有了保家卫国、捍卫和平的核力量。交流邓稼先故事1950年8月,邓稼先在美国获得博士学位九天后,便谢绝了恩师和同校好友的挽留,毅然决定回国。同年10月,邓稼先来到中国科学院近代物理研究所任研究员。在北京外事部门的招待会上,有人问他带了什么回来。他说:“带了几双眼下中国还不能生产的尼龙袜子送给父亲,还带了一脑袋关于原子核的知识。”此后的八年间,他进行了中国原子核理论的研究。

三、教学建议第一课时:1. Lead in (Vocabulary)A) Before class, teacher should collect some pictures of working places. For example: Bank, TV Station, Restaurant, Police Station, Hospital ...B) In class, show students the pictures (PowerPoint, OHP). Ask students to tell the name of the working places and the name of the jobs.Shop assistant, doctor, actor, reporter, police office, waiter, bank clerk, studentC) Do exercise 1a and 3a.2. Bingo GameAsk groups of students to make up pairs of cards with a job on one and the related workplace on the other. For example, waiter / restaurant, teacher / school, doctor / hospital. Encourage students to use both the job / workplace combinations in the book and the ones that students came up during class discussions. Be sure they have twice as many sets of cards as there are students in the group. They can make two sets of cards for a single job / workplace, if necessary. Then have each group mix up its set of cards and hand their cards out in random order. Each time a student gets a pair of cards that match, he or she can lay these cards down. The goal is to have no cards in your hand at the end.3. Task OneA) Ask students to work in pairs and ask the partner what does he / she want to be in the future.e. g. :What do you / does he / does she want to be?I want to be a.Why?Because it's (adj).B) Vocabulary: Section B, 1a4.

五、教学Section B-2c1. Pair work: What do you think of the belt/sunglasses/…? What does your father/mother/… think of your scarf/belt…?2. Group work(1). Teacher shows some different kinds of school uniforms (制服)and asks : “ What do you think of your school uniforms? If you have a chance to choose your school uniforms, what kind would you like to choose?”(2). Discuss in groups.(3).Get some Ss to report in class.说明:这一步旨在让学生运用已有的语言知识谈论对事物的看法和意见,并简单阐明理由,培养学生的主动思维能力和运用英语的能力。六、教学拓展调查电视节目的收视率任务:调查你周围的人对现在各种电视节目的反响。活动过程:1.教师布置任务,让学生调查周围的人(包括他的亲戚朋友和邻居)喜欢收看哪方面的电视节目。2.学生进行调查活动,运用本单元所学的句型What do you think of….? (Why?)What's your favorite game shows?What do you think of talk show?I doesn’t mind it.I like it.I love it.I can’t stand it.3.记录下排在前10位的TV Program,填写调查表,比较其收视率。
