预设 第一组:(1)语言精准又生动形象,首先用长句总写各拉丹冬的变化多端,然后接连用短句,简笔勾勒各拉丹冬巍峨高大、棱角分明的特点,张弛有度,富有音乐美感。(2)用语精简而准确,形象性强,短促的句子节奏,很好地表现出冰体形状之多令人目不暇接,最后部分节奏放缓,形成一种张弛有度的音乐美,让句子又融入段落主体比较舒缓的节奏中去。第二组:(1)将自己的身体不适比喻为“小震”“大地震”,描写自己由于病痛而行动迟缓的“犹如霹雳舞的‘太空步’”,幽默之中,透露出作者乐观、坚强的精神和对探险事业的热爱。 (2)用“分外利落”形容自己拍摄冰山时跌倒骨裂的情景,好似没有痛苦一般。这幽默调侃之中,透露出作者乐观、坚强的精神。第三组:(1)“眩晕”原指一种症状,感觉到自己或周围的东西旋转,这里指“浩浩苍苍”的美景令人目不暇接,令人不知该看什么;“卖弄”原指有意显示、炫耀,含贬义,这里指大自然的无穷创造力在各拉丹冬展现得淋漓尽致。
预设 示例1:“板块背上驮着许多大陆,当板块向一个或另一个方向运动时,大陆也随之一起运动。”“驮”字形象地写出了大陆漂移的样子,使抽象的理论变得生动、有趣、易懂。示例2:“位于南极中心部位的南极洲是全球的大冰箱。”运用了打比方的说明方法,形象地说明了南极洲寒冷的程度和南极洲在地球生态环境中的重要位置。 示例3:“一立方英寸被压扁的沙子比一立方英寸普通的沙子要重得多。”运用作比较的说明方法,说明同体积被压扁的沙子比普通沙子重得多的特点。【设计意图】本环节设计的三个层次的语言赏析,让学生深入文本体会、学习语言简明精练、逻辑性强、幽默风趣的特点,提高学生的语言鉴赏能力,为今后的说明文写作夯实基础。四、总结拓展,激发思维所选的两篇课文就同一对象——恐龙从不同角度思考,从而发现新的论据或得出新的结论。文章给了我们一些有益的启示:不同领域的科学发现可以互相启发,从而有新的发现;要学会从不同角度思考问题。选择下面两个探讨任务之一课外完成。
预设 示例:班上分享个人读书经验大家好!既然今天是交流读书体会,那么,我想结合自己的读书体会和大家聊聊读书。一个爱读书的民族,必定是一个文化素质较高的民族;一个爱读书的人,也必定是一个文化素质较高的人。读书能开阔我们的视野,提高我们的写作水平;读书能提升自身修养,丰富我们的人生底蕴。读书是我们精神的呼吸,能让人保持平淡的心境,变得博爱而无私。为了让我们的生活和心灵变得轻盈一些,我们需要读书。那么,应该怎样读书呢?其一,要择书而读。需要的才是最适合的,读适合的书才能有良多收获。如果没有特别需要的书要读,可以读经典。经典是经过岁月沉淀下来的人类智慧的结晶,可以让我们触摸先贤的思想,以充实自身。其二,要读而有术。要对好书反复品味,将其内化吸收,然后进行批判性阅读,有自己的思想主张和拓展探究价值判断;在读书过程中与作者进行辩论,最后形成自己的思想体系,为我所用,而不是让自己的脑袋成为别人思想的“跑马场”。
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。
刘绍棠,中国当代著名乡土文学作家,1936年2月出生于河北通县(今北京通州区)大运河畔的儒林村,1949年开始发表作品,一生留下了500多万字的乡土文学作品,包括《地火》《京门脸子》等多部长篇小说,《蒲柳人家》《运河的桨声》等多部中篇小说,以及《青枝绿叶》《蛾眉》等多部短篇小说集。他的作品在国内多次获奖,在国际上亦有影响。刘绍棠的作品内容各不相同,但都艺术地再现了其家乡大运河畔不同历史时期的风土人情和社会风貌,描绘了充满诗情画意的乡风水色、世俗人情。20世纪80年代以来,刘绍棠不遗余力地倡导乡土文学,创作上坚持“中国气派,民族风格,地方特色,乡土题材”。文学评论家指出,他的作品格调清新淳朴,乡土色彩浓郁,形成了独具特色的大运河乡土文学风格。
教师指导:每个表演小组可选剧务两名,负责服装道具的制作和音乐的准备。负责服装道具的同学要动手能力强,有一定的美术功底。负责配乐的同学对音乐有所了解。在适当时候教师可以给剧务同学提供相应的帮助。【设计意图】教师在指导的基础上,组织学生进行排练,排练过程中把自主权交给学生,充分锻炼学生的合作能力。三、合作排练根据研讨反馈,导演组织全剧组排练,剧务根据表演需要设计制作场景、服装,演员反复合练,及时发现表演、舞台、配合等各方面的问题,为“任务三”正式演出做好准备。本次教学设计的任务是准备与排练,学生虽有参与的热情,但组织剧组,担任导演、剧务等工作尚缺乏相关经验,因此在活动中,老师在其中承担顾问工作,给予必要的指导。对于并未接受过专业表演训练的同学们来说,要演好剧情,演活剧本并非易事,还需要多尝试,多训练。因此,在进行必要的排练指导后,就放手让学生去排练。
从以下话题中任选其一(也可自选话题),写一篇作文,谈谈自己对剧本和戏剧表演的认识。不少于600字。①我为什么对“他”印象最深②舞台说明不只是“说明”③戏剧冲突面面观④台词应该怎样说⑤肢体语言很重要⑥配角也要演到位⑦“好戏”是配合出来的2.技法点拨。①写作时,结合对剧本和戏剧表演的认识,发表自己的见解和看法,力求明白晓畅,切勿写得深奥晦涩难懂。②阐述认识时,要列举剧本和戏剧表演的实例进行分析,便于读者理解和信服。③涉及把握不准的专业术语需查阅相关资料、典籍,规避错误,以免误导读者。④明确提出观点,筛选典型事例作为依据,分析材料与观点之间的关系。师:无论是选择哪一个话题,都要结合具体的实例进行分析,不能只列条目而无内容。针对某一戏剧或谈人物,或谈舞台说明,或谈矛盾冲突,或谈肢体语言,或谈相互配合等;也可以针对某个话题,列举多部戏剧中具体的一句、一段话,或一幕。
【教学理念】 1.整体感知课文内容,理清文章思路。2.培养学生筛选信息能力,了解纳米的有关知识和应用前景。3.激发科学兴趣,培养学生勇于大胆想象的科学精神。【教学流程】一、谈话引入,激发兴趣。1.今天我们来学习一篇新课文《纳米技术就在我们身边》(板书课题)。2.以前听说过“纳米技术”吗?你了解纳米技术吗?是怎么了解到的?预设:我通过预习课文了解到“纳米技术”就是研究小小物质新奇特性的一门学问。预设:我是通过查找资料了解什么是纳米,什么是纳米技术的。二、通读课文,了解大意。1.检查课文朗读。出示课文中的科技术语和句子。先组内相互听读纠正,然后全班交流。词语:除臭技术 纳米缓释技术 长度单位 纳米涂层 碳纳米管 纳米吸波材料 探测雷达波。句子:纳米技术就是研究并利用这些特性造福于人类的一门新学问。2.自由交流:读了课文,你知道了什么?
一、图片导入,激发兴趣。1.导语:大家还记得在科幻世界里那些随意消失变化的人吗?还记得在神话世界里,孙悟空的七十二变吗?现在所有这一切都不是在疯狂的科幻世界里,不是在神奇的神话里,而是在离我们也许只有几年之遥的纳米时代!那么什么是纳米?什么是纳米技术?大家想不想了解有关这方面的知识?2.展示图片:【课件出示2】图1.纳米机器人(描述的是一个纳米机器人在清理血管中的有害堆积物。由于纳米机器人可以小到在人的血管中自由地游动,对于像脑血栓、动脉硬化等病灶,它们可以非常容易地予以清理,而不再用进行危险的开颅、开胸手术。)图2.纳米技术制作的中国地图(这是中国科学院化学所的科技人员,利用纳米加工技术在石墨表面,通过搬迁碳原子而绘制出的世界上最小的中国地图。这幅地图到底有多小呢?打个比方吧,如果把这幅图放大到一张一米见方的中国地图大小的尺寸,就相当于把该幅地图放大到中国辽阔的领土的面积。)
【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.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。

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.

单元整体说明(一)单元教材分析本单元的核心话题是描述动物和表达个人喜好,以及句式why do you like…? Because…。这也是本单元的教学重点。通过本单元的学习,学生应能较流利地运用所学词汇和句型描述动物,表达个人喜好。(二)单元知识结构1.词汇动物名称 tiger, elephant, koala, dolphin, etc.词汇描述性形容词: smart, cute, ugly, clever, shy, etc.国家名: Australia, South Africa2.句型Why do you like koala hears? Because they are cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(三)单元整体目标1.Master the vocabulary2.Master and use: Why do you like koalas? Because they am cute.Where are pandas from? They're from China.What animals do you like? I like dolphins.(四)单元教学重难点一览(五)单元学情分析学生此前已经学过由why, where, what 引导的特殊疑问句句型,具有了学习本单元知识的认知前提。形形色色的动物能激发学生的好奇心,产生了解它们的欲望,这有利于本单元知识的教学和学生学习兴趣的培养。
