    部编人教版四年级下册《海的女儿》教案

    《海的女儿》介绍小人鱼亲自参加王子的婚礼,忍受身体和精神的苦痛,一步步变成泡沫,走向死亡的故事。这是一个凄美的爱情故事。成功之处:在教学过程中,以学生为主体,让学生在读通文章之后出示一些重点语句。我在教学中能够放手给学生,让他们在文本中充分品味挖掘语言的魅力内涵。让学生边读边想象,由理解句子表面的意思过渡到感悟作者蕴藏在句子中的情感,小组讨论阶段,学生在充分讨论的过程中对作者的情感就有了一定的感悟,再通过教师的点拨指导,认识上就更深一层次,对今后阅读安徒生的作品帮助很大。不足之处:由于注重了写作方法的学习,对朗读的指导就比较少,在以后的教学中要注意教学时间的合理分配。

  • 人教部编版语文九年级下册山水画的意境教案

    人教部编版语文九年级下册山水画的意境教案

    意境是什么?意境是艺术的灵魂。是客观事物精粹部分的集中,加上人的思想感情的陶铸,经过高度艺术加工达到情景交融、借景抒情,从而表现出来的艺术境界、诗的境界,就叫作意境。艺术从生活中来,但它不等同于生活。艺术与生活是辩证关系,生活是艺术唯一的源泉,艺术来源于生活,是现实生活的反映,但艺术中反映出来的生活,可以而且应当比实际的生活更高,更典型,更理想。就是说,艺术又要求对生活进行高度集中和概括,要求典型化、理想化,从而创造出比现实更美好、更富有诗意、更理想的艺术境界,创造出革命时代新的意境。这是革命的现实主义与革命的浪漫主义相结合的创作方法最基本的一条,也是其他的创作方法所不及、难以充分达到的。千余年来,中国山水画为什么那么发达,这与河山壮丽是分不开的。中国向来把江山、河山、山水作为祖国的象征或代词。

    5.请你根据前面的探究,总结本文的论证思路。明确:作者首先通过论述作者、读者以及文字之间的联系来明确读者欣赏文艺作品的本质,即“接触作者的所见所感”,然后以赏析王维诗句为例,从正反两个角度论述了驱遣想象力的重要作用。目标导学三:赏析语言,领悟内涵文中有许多句子,都有十分深刻的文艺观,它们或有十分深刻的内蕴,或有写作值得借鉴的实用价值,请阅读下面几句,谈谈你对它们的理解。(1)文艺的创作决不是随便取许多文字来集合在一起。明确:任何一篇文艺作品,都是文字集合起来的,但这是一种有着内在逻辑顺序的结合,具有文本表现中的一般技法,既表现了内容也传递着作者的思想感情。因此,这样的文章绝不可能随意拼凑,须由作者有意识、有目的、有逻辑地创造,而在完成时又符合自然的特点。(2)作者着手创作,必然对于人生先有所见,先有所感。

    部编版语文九年级下册《山水画的意境》教案

    2.作者要说的是山水画的意境,为什么要在第一部分大篇幅分析诗歌的意境。明确:按照作者的观点,“孤帆远影碧空尽,唯见长江天际流”两句,完全描写自然的景色,然而就在这两句里,使人深深体会到诗人与朋友的深厚友情。描写自然的景色与绘出景色无异,且作者提到“意境就是景与情的结合”,可见诗歌中的意境与山水画的意境是相通的,并无二致。因此,作者在这里以已经学习过的诗歌意境为例,也就能更好地诠释山水画的意境。3.“意境的产生,有赖于思想感情,而思想感情的产生,又与对客观事物认识的深度有关。”作者是如何论述此观点的?你认为这个观点正确吗,请结合你的个人经历做简要说明。明确:作者以齐白石画虾为例来论证了他的观点。这个观点正确,如我们知道松树的耐寒可以象征它的坚忍,而当我们在雪地里认真观察,会发现只有松树傲然长青,松针贯穿积雪依然向上,此刻,我们会真正感受到这种坚忍的品质是那样真实。

    例2是面包房买卖面包的情境。解决问题的重点是学会使用小括号列综合算式,并了解小括号的作用。通过学生熟悉的购买面包的情境,解决“还剩多少个”这个实际问题。仍然可以引导学生从不同的角度思考问题,启发列式为54-8-22或为54-(8+22)。第二种解法的综合算式,教材中特别强调“如果写成一个算式,应该使用小括号”,并明确“计算时先算小括号里面的”。因为是初次在列式时需要使用小括号,如果学生产生疑问,教师可组织学生通过回顾旧知,利用现实情境,明确使用小括号的必要性及使用方法。教学例2时可以采用与例1相似的教学方式。首先让学生观察下页图,也可以利用电教媒体创设情境,由学生提出问题,并启发学生思考如何解决。让学生充分交流研讨,畅谈自己的想法,然后着重说明解决问题的思路。列式计算时可以先分步列式,同时强调两种列式方法的内在联系,列综合算式时着重说明使用小括号的目的。

    1. First, ... then, ... next, ... finally, ...首先,……然后,……接着,……最后,……这是英语中表达做某事的步骤的一种说法。如果步骤较多,还可以说:first-next-after that-later on-finally/at last通常你会听到说英语国家的人在说 first, next, then, finally 和后面的内容时,他们会做一些停顿。这样就能提前告诉听者接下来讲的是一系列的步骤。这一点在朗读和听力中应特别注意。2. how many, how much均为疑问词,同是“多少”,但用法不同。请看:how many修饰可数名词复数,how much修饰不可数名词。但在用法上,同学们常犯如下错误:1) [误] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容词,常修饰名词作定语,故后面跟名词。2) [误]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修饰不可数名词时,谓语动词用单数。how many与how much的区别可简记为:前how many:问“多少”,复数名词后面跑;how much问“多少”,不可数名词单数好。前者答语用基数词,后者答语用数量关系。
