3.进一步体会力是产生加速度的原因,并通过牛顿第二定律来理解匀速圆周运动、变速圆周运动及一般曲线运动的各自特点。(三)、情感、态度与价值观1.在实验中,培养学生动手、探究的习惯。2.体会实验的意义,感受成功的快乐,激发学生探究问题的热情、乐于学习的品质。教学重点1.体会牛顿第二定律在向心力上的应用。2.明确向心力的意义、作用、公式及其变形,并经行计算。教学难点1.对向心力的理解及来源的寻找。2.运用向心力、向心加速度的知识解决圆周运动问题。教学过程(一)、 引入新课:复习提问:匀速圆周运动的物体的加速度——向心加速度,它的方向和大小有何特点呢?学生回答后进一步引导:那做匀速圆周运动物体的受力有什么特点呢?是什么力使物体做圆周运动而不沿直线飞出?请同学们先阅读教材
让学生仔细聆听美妙的音乐,合作讨论,加深理解。(1)本诗文中的“兰芝被遣”和“兰芝抗婚”的情节,可与乐曲展开部第一阶段“逼嫁抗婚”对比阅读。文中的刘兰芝是在封建礼教的压迫下被遣归及被迫“改嫁”,刘兰芝与祝英台一样都进行了抗争。乐曲中的乐器奏出了具有威胁力的封建势力的主题,代表着封建势力的凶暴残酷,同时叙述了祝英台的悲痛和不安心情,表现了控诉、抗争的感情。(2)本诗文中的“夫妻誓别”的情节,可与乐曲呈示部中的结束部“长亭惜别”对比阅读。文中刘兰芝与焦仲卿的誓别。二人分手之际,依依不舍,“举手长劳劳,二情同依依”。乐曲中梁祝分别时依依不舍又充满悲伤,音调抒情徐缓。让学生在徐缓的音乐中去感受刘兰芝与焦仲卿生离死别的痛苦。
四、品味诗歌艺术1、诗人是如何表现其品质的?运用了什么修辞手法?产生了怎样的表达效果?明确:诗句“扈江离与辟芷兮,纫秋兰以为佩”很好地体现了诗人光辉俊洁的人格。用“江离”“辟芷”“秋兰”三种香草来装饰自己,比喻自己,极其生动形象地表现了诗人自己美好的精神世界,使诗歌充满了浪漫主义气息。2、《离骚》中作者常以“香草”、“美物”来比喻自己、贤士和君王,并表达政治理想,这是《离骚》的一大艺术特色,这种方法叫做“移情法”,即不直接说出自己想说的话,而是把它寄寓于某一物上,也就是“移情于物”,这种方法在古典诗词中广泛运用,在政治不清明的时代,借用“移情”,可言难言之语,抒难抒之情。请找出相关的诗句,说说诗人是怎样运用这些比喻来表达政治理想的。
教学设想:本节课的主题是“生命之绿,璞玉心灵”,用圈点批注法解读爱绿的感情,让学生在批注中明确“绿”的象征意义,而不只是结论的传递。同时借助于阅读、感受和理解把握作者对绿的认识是不断升华的,由一般对生命希望之绿的喜爱,到与绿交往后被它的不畏强暴,永远向阳的精神所折服,最后在特定的时代背景下绿在作者的心目中已经成了我们民族不屈精神的象征。让学生评中求解,评中悟情,评中明理,评中品味。教学进程:一、导语上节课我们学习了朱自清的《绿》,初步了解了读书动笔的基本方法,这节课我们继续用圈点批注的方法来学习陆蠡的散文《囚绿记》。二、释题师:看标题,囚绿之“绿”在文中具体指什么?(一株常春藤)“囚”就是囚禁的意思,那题目就是记述囚禁绿色常春藤的经过。三、圈点、把握情节作者为什么要囚绿呢?文中除了写“囚绿”之外,还写了哪些有关绿的意念和行动?带着这样的质疑用自己喜欢的方式朗读课文,请同学们圈点出疑难字词,或结合书下注释,或同学合作解决,解决不了的,可提出来我们共同解决。标注段落节次。勾画出表现作者对绿意念和行动的句子。
【设计思想】诗歌教学的关键是感受诗景,体味诗情,领悟诗意,在此基础上孕育理解能力、鉴赏能力和审美情感。诗景、诗情、诗意均由文字来承载,把握文字组合的张力,是读诗赏诗的抓手。杜甫的诗歌素以炼字精深、涵盖深远著称,以《登高》而言,往往淡淡一字,平平一语,便笼大千于方寸,缩古今于一瞬。故细读文本,咀嚼字句,便是赏景、悟情、会意的基本路径。其次,不朽名作的特点是寄寓深广,古今评价甚多,见仁见智,不一而足。这正是培养学生问题意识、探究意识的极好凭借。第三,诗为语言之精华,是诗人心里涌出的情感之流。诵读乃赏诗之要着,精心感悟之时,设身处地,心惟口诵,是理解诗意的关键一步。基于是,笔者作如下同课异构,殊途同归。【教学目标】1.理解本诗所绘之景、所抒之情及绘景、抒情之法。2.学会用意象叠加法、字句推敲法、诵读体验法等欣赏诗歌。3.感受杜甫心系苍生、情寄邦国、忧国忧民、兼济天下的博大情怀。
(一)导入[以视频欣赏导入]同学们,刚才欣赏的是大家熟悉、喜欢的电视剧《亮剑》中的精彩片段——李云龙论述什么是“亮剑”精神?同学们听后觉得好不好?牛不牛?“亮剑”精神简单理解就是敢于与强大的敌人(对手)做斗争,无论对手多么强大,都要满腔勇气和信心,永不放弃、永不言败,要敢于亮剑……今天我们一起来学习世界100部著名文学作品之一、美国里程碑式30部文学作品之一的世界名著——海明威的《老人与海》,看看主人公桑提亚哥“硬汉”性格和李云龙“亮剑”精神有么相似的地方。(请同学们翻到课文,课件显示课题《老人与海》)(二)走进作者:请同学们自己谈收集到的有关海明威的资料,然后教师梳理出下列核心内容识记:(课件显示)海明威(1899~1961),美国现代作家,20世纪美国文学史上最耀眼的名字之一。早期作品表现了第一次世界大战青年一代的彷徨情绪,以“迷惘的一代”的代表著称。20世纪末回到美国,写了不小以拳击家、渔民、猎人等为主人公的短篇小说,创造了“硬汉子”性格。
(1)请同学们结合日常生活实例和教材分析说明人类要在世界各地消除贫困并保持人口的合理容量任务的艰巨性?(2)采取何种措施才能更好的解决这一问题的出现?教师总结(1)现实中的人口问题(如人口过快增长、人口城市化和人口老龄化等)引发了严重的资源问题和环境问题。①发达国家的人均消耗资源量很大,索取资源和转嫁有害生产的地域超出了本国的范围。②发展中国家不仅人口数量多,人均消费水平低,而且一些国家的人口仍在快速增长。若在现有的经济基础上,把发展中国家人均生活质量提高到与发达国家相当的水平,所引发的资源短缺和环境问题将会相当严重,解决的难度也很大。(2)I就整个世界来说:①国际社会要倡导各国,尤其发展中国家要尽最大可能把人口控制在合理的规模之内;②建立公平的秩序,保证大多数人拥有不断追求高水平生活质量的平等权利。
巴金在十年浩劫中的大致经历:放弃包弟并没有换得保全一家人,1968年8月,巴金被关进牛棚改造,随后经受了大字报、挂牌游街等形式的批斗。1970年,到农村改造,掏大粪、喂猪、背稻草、种地……1972年,妻子萧珊在饱受精神折磨后患上癌症,病逝。巴金的儿子在劳动改造的过程中也饱受精神和肉体上的折磨,性格变得内向抑郁,疾病缠身。此时,巴金69岁。巴金曾在《病中》一文写道:“当姚文元拿着棒子的时候,我给关在牛棚里除了唯唯诺诺之外,敢于做过什么事情?十年间我不过是一条含着眼泪等人宰割的牛。”小结:(幻灯片12)社会是病态的社会,政治是高压的政治,人性是扭曲的人性。十年文革,十年浩劫,给多少人留下了累累不可弥合的精神创伤。即使一条小狗,也可能摆脱不了“文革”无情的迫害,比如包弟,比如艺术家邻居的小狗。
请问,作者究竟听到歌声没有?”学生回答:“没有。”“这里是比喻,因为这里用得是‘仿佛’一词……”对,是比喻。也就是说,作者是用歌声来比喻荷香,是吧?“但是,“荷香与歌声有什么可比的共同点吗?”“荷香与歌声都是断断续续、若有若无的。”“而且朦朦胧胧的。”“对。“荷香和歌声都是‘缕缕’的、‘渺茫’的。这是比喻。这是一种特殊的比喻,钱钟书先生把它叫做‘通感’。人们通过视觉、听觉、触觉、味觉、嗅觉等五官感知外界事物时,在一般情况下,彼此不能交错;但在特殊情况下,五官功能却能出现互相转化、彼此沟通的现象叫“通感”,也叫“移觉”。举几个例子来说明:诗人艾青曾写诗这样描绘日本著名指挥家小泽征尔:‘你的耳朵在侦察,你的眼睛在倾听……’这也是通感。又如:“那笛声里有故乡绿色平原上青草的香味,有四月的龙眼花的香味,有太阳的光明。”(郭风《叶笛》)
五.研习第一段:1.诵读指导要处理好句中停顿2.请学生对照注释翻译本段重点词句:学不可以已已:停止。青,取之于蓝而青于蓝于:从;比。木直中绳中:zhàng符合,合于。虽有槁暴,不复挺者,揉使之然也有通又,揉通煣,以火烘木,使其弯曲。然:这样。翻译:故木受绳则直,金就砺则利,君子博学而日参省乎己,则知明而行无过矣。所以木材经墨线画过(再用斧锯加工)就直了,金属刀剑拿到磨刀石上(磨过)就锋利了,君子广博地学习并且每天对自己检验反省,就能智慧明达,行为没有过错了。3.本段是从哪个角度论述中心论点的?明确:本段是从学习的意义这个角度论述中心论点的。荀子认为人的知识、道德、才能都不是天生成的,而是后天不断学习获得的,学习的意义十分重大,所以学习不能停止。4.本段中几个比喻句是为了说明什么道理?学生讨论发言,教师明确:
小结人们对待祥林嫂这个“嫁而再寡”的不幸女人态度:①、鲁四老爷的态度:不让她干祭祀的活(71、73、75、108通过四婶先后三喊“你放着罢”,杀人不见血地葬送了祥林嫂的性命。而其中尤以最后一次对其打击最大)。鲁四老爷站在顽固维护封建宗法制度的立场上,从精神上残酷地虐杀她。他暗暗地告诫四婶的那段话,就是置祥林嫂于死地而又不露一丝血痕的软刀子。②、鲁四婶的态度:鲁四婶是“大户人家的太太”,头一次留祥林嫂是看她能干,祥林嫂被婆家绑架走以后,她害怕给自己家惹麻烦。之后她惦念祥林嫂不是因为关心她的命运,而是自己的佣人都没有祥林嫂那样可心。以后祥林嫂再来,她“起初还踌蹰”,后来倒是真心怜悯祥林嫂,留下她。但是祥林嫂不像过去那样灵活能干了,四婶开始“不满”,进而“警告”,最后把祥林嫂赶出家门。可以说,四婶只是把祥林嫂当成一件工具罢了,没有把她当人来看。

This teaching period mainly deals with grammar “restrictive relative clauses.” To begin with, teachers should lead students to revise what they have learned about the relative pronouns and relative adverbs. And then, teachers move on to stress more special cases concerning this grammar, such as the “preposition+ relative pronouns which and whom” and cases where we can omit the relative pronouns. This period carries considerable significance to the cultivation of students’ writing competence and lays a solid foundation for the basic appreciation of language beauty. The teacher is expected to enable students to master this period thoroughly and consolidate the knowledge by doing some exercises. 1. Guide students to review the basic usages of relative pronouns and adverbs of attributive clauses.2. Lead students to learn to use some special cases concerning restrictive relative clauses flexibly.2. Enable students to use the basic phrases structures flexibly.3. Strengthen students’ great interest in grammar learning.1. Help students to appreciate the function of relative pronouns and adverbs of attributive clauses in a sentence2. Instruct students to write essays using the proper relative pronouns and adverbs of attributive clauses.本节语法思考:定语从句在复合句中的作用是什么? 关系词有哪些?定语从句在复合句中的作用相当于形容词,它在句中作定语修饰名词或代词。他们在先行词和定语从句之间起到联系作用,同时在意义上代表先行词并在定语从句中担任一个成分。被定语从句所修饰的词称先行词,定语从句一般放在先行词的后面。
