    人教版高中地理必修2工业地域类型教案

    1.生产上的联系:有投入——产出的关系工业生产的过程复杂,工序繁多,往往需要经过多家工厂的加工才能完成一种产品的生产过程。因此,在这些工厂之间就存在着产品与原料的联系。一家工厂生产的产品是另一家工厂的原料,这两家工厂之间就形成了工序上的工业联系。2.非生产上的联系:如地理空间上的联系布局在同一个工业区内,共同利用工业区的道路、供水、供电、通信等基础设施以及其他生产、生活服务设施,或者共同利用当地廉价的劳动力,形成了空间利用上的工业联系。我国许多地方的经济技术开发区就是建立在这种工业联系基础上的。(二)工业集聚1.形成具有工业联系的一些工厂往往近距离地聚集起来,形成工业集聚现象。2.工业集聚可获得效应(1)工业集聚可以加强企业间的信息交流和技术协作,降低中间产品的运输费用和能源消耗,进而降低生产成本,提高生产效率和利润,取得规模效益。

    人教版高中语文必修2《荷塘月色》教案3篇

    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》)

  • 人教版高中语文必修3《登高》教案2篇

    人教版高中语文必修3《登高》教案2篇

    【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。

  • 人教版高中语文必修3《蜀道难》教案2篇

    人教版高中语文必修3《蜀道难》教案2篇

    【明确】“一夫当关,万夫莫开”言剑阁有易守难攻的险要形势,暗示中央朝廷的部队很不容易打进来,因而野心家可以据险发动叛乱,“化为狼与豺”,搞地方割据。如果割据势力之间出现矛盾冲突,难免要发生混战,结果必定是“杀人如麻”。诗人这番预言在十多年后就得到了证实:从上元二年到大历初即有段子璋、徐知道、崔旰等人相继发动叛乱。诗人的意图是要严防野心家发难。诗人从剑阁的险要引出对政治形势的描写。他化用西晋张载《剑阁铭》中形胜之地,匪亲勿居的语句,目的在于劝人引以为鉴戒,警惕战乱的发生,并联系当时的社会背景,揭露了蜀中豺狼的磨牙吮血,杀人如麻,这既是描写蜀道猛兽,又是影射政治黑暗的双关语句,表达了对国事的忧虑与关切,为诗篇增加了现实的内涵、深厚的意蕴。唐天宝初年,太平景象背后正潜伏着危机,后来发生的安史之乱,证明诗人的忧虑是有现实意义的。

  • 人教版高中语文必修3《祝福》教案2篇

    人教版高中语文必修3《祝福》教案2篇

    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。

  • 人教版高中历史必修2古代商业的发展教案

    人教版高中历史必修2古代商业的发展教案

    中国古代商业的发展有哪些表现?综观中国古代历史,商业在不同的历史时期有不同的表现。主要表现在:(1)商业活动的场所的变化:先主要在城市中进行,后来农村集市贸易逐渐发展。唐时加快,明清时突出,出现了专业性的市集(如丝市、叶市、猪市等),以至逐渐形成了新兴的市镇(有的更是专业性的集散市集);而不是先有农村商业,而后才有城市商业的发展。(2)交易内容的变化:商业开始时以贩运、交流地区间的土特产品,经营统治者所需要的奢侈品为主要内容,以后随着商品货币经济的发展,市场商品种类增多、行业分细,为一般人民所需要的主要农副产品以及城市手工业所生产的大小商品在整个流通界地位提高。这种情况在宋代已经显现。(3)交易媒介的变化:商品交换最原始的形态是物物交换,不存在交易的媒介。随着商品交换的内容和地域的扩大,出现了以贝壳等为代表的一般等价物。

  • 人教版高中历史必修2古代的经济政策教案

    人教版高中历史必修2古代的经济政策教案

    【本课小结】本课主要讲述了古代中国土地制度的发展情况。明清的资本主义萌芽,是中国封建社会内部产生的新生事物。但资本主义萌芽受到的封建王朝“重农抑商”和“闭关锁国”政策的阻碍。正是这种“闭关锁国”与“重农抑商”政策相结合,导致了资本主义萌芽的缓慢发展,并使中国与世隔绝,不能及时学习西方先进的科学技术,使中国落后于世界潮流,从而埋下了日后落后挨打的祸根。【智能训练】阅读下列材料:材料一自耕农是封建国家直接剥削的对象。为了保证赋税、徭役的供应,封建国家历来关注这一阶层的存在。“稳定小农”是封建王朝长治久安的良策,每一个新王朝建立时,对此尤为关注。他们总是采取鼓励垦荒等政策,积极培植自耕农。诚然,自耕农这一阶层是很不稳定的,经常分化。

  • 人教版高中历史必修2大众传媒的变迁教案

    人教版高中历史必修2大众传媒的变迁教案

    【课后研讨】当互联网正大踏步走进人类生活的时候,人们对网络作用的认识似乎还是模糊不清。一种意见认为,作为中学生,他们上网的机会很多,互联网向他们展示了各类知识结构,网络为他们提供了大量信息,又给他们提供了一个接触社会的个性化和国际化的空间,给了他们一个展示自身能力的大舞台,所以他们对于知识选择的灵活性大大增加,学习的主动性也大大提高,学习的内容自然大大超出了狭隘的课本范围,这对于学生能力的提高应是大有裨益的。另一种意见认为,网络的出现无疑为推进素质教育提供了一块绿洲.但部分中学生上网更多的是为了消遣和娱乐,因为网络--这个完全虚拟的世界是他们放松自己的最佳场所。同时也许正基于这一点,家长和师长才会对中学生上网出现不同程度的抵制,因为他们认为网上娱乐分散了他们过多的精力,会对学业造成影响;更为重要的是,他们害怕网络上的不良信息对他们的身心不利。

  • 人教版高中历史必修3美术的辉煌教案2篇

    人教版高中历史必修3美术的辉煌教案2篇

    画中的诸多图像反映了画家对于传统绘画因素的吸收。那个怀抱死去孩子的母亲图像,似乎是源自哀悼基督的圣母像传统;手持油灯的女人,使人联想起自由女神像的造型;那个高举双手仰天惊呼的形象,与戈雅画中爱国者就义的身姿不无相似之处;而那个张臂倒地的士兵形象,则似乎与意大利文艺复兴早期某些战争画中的形象,有着姻亲关系。由此可以看出,毕加索不仅是一位富于叛逆精神的大胆创新者,同时也是一位尊崇和精通传统的艺术家。教师须强调:现代主义美术是现代美术流派的总称,现代美术流派众多,多姿多彩,但它们也表现出许多共同的特征。在技法上,它们大都反对传统的写实主义,追求新奇,空间结构错乱,色彩配置随意,点线紊乱,缺乏透视可谓它们共有的特点。在创作主旨上,它们都主张强调自我,表现个人情感和内心世界。可以说,现代美术艺术再现了20世纪西方世界的精神状况。

  • 人教版高中政治必修3体味文化教案2篇

    人教版高中政治必修3体味文化教案2篇

    3、文化是人们的一种素养(1)人的文化素养是在社会生活、实践中形成的。每个人所具有的文化素养,不是天生的,而是通过对社会生活的体验,特别是通过参与文化生活、接受知识文化教育而逐步培养出来的。文化素养的形成,离不开生活、实践和教育。人们在社会实践中创造和发展文化,也在社会生活中获得和享用文化。(2)人的文化素养表现在日常言行中。教师活动:引导学生阅读教材7页“公交车漫画”材料,并思考所反映的问题学生活动:积极思考并讨论问题教师点评:人们的精神活动离不开物质活动,人们的文化素养总是要通过他在日常生活中的言行、在社会实践活动中的表现等表现出来。我们通过观察人们的社会行为,就可以从中透视人们的精神世界和精神生活。4、文化的传承和发展离不开物质载体。社会文化和精神产品离不开物质载体,一个时代的文化和精神产品,往往是这一时代社会发展轨迹的反映。
