黄梅戏是安徽省的主要地方戏曲剧种,原名“黄梅调”或“采茶戏”。流行于安徽、湖北、江西、江苏等地。他的起源大约可以追溯到清朝乾隆年间,但形成一个完整的剧种,是十八世纪后期在皖、鄂、赣三省毗邻的黄梅县形成的,其中一支逐渐东移到安徽省怀宁县为中心的安庆地区,与当地民间艺术相结合,用当地语言歌唱、说白,形成了自己的特点,被称为“怀腔”或“怀调”,这就是今日黄梅戏的前身。主要剧目有:《天仙配》、《夫妻观灯》、《打猪草》等。黄梅戏《打猪草》由“二小”组成,人物是陶金花、金小毛,一个打猪草一个看竹笋。陶金花在打猪草时.拔草用劲过大,不小心碰断了金小毛家两根竹笋,慌忙用草将笋盖上,这时,在树上看笋的金小毛看见了,认为她有意偷笋,踩破了她的篮子。小姑娘哭着拉他去见妈妈,要他赔篮子。金小毛无奈,将舅母让他买盐的二百文钱赔她,她知道底细后不要金小毛赔了,说:“只要心意好,人好水也甜”,金小毛又把断了的竹笋一起送她,陶金花提不动,又帮着她送到家里。一路上边走边唱盘歌《对花》,什么花都问遍了,终于回到家中,金花妈妈不在家,金花打了三个鸡蛋,泡一碗炒米招待小毛,小戏在欢乐的气氛中结束了。在封建礼教统治森严的情况下,男女青年这种自由交往具有反封建的意义,剧中所表现的青春的活力、逗趣的语言和优美的曲调,使人如沐春风,具有亲切感人的魅力。《打猪草》的可贵之处就在于毫无造作,从唱词到表演都再现了生活的真情,犹如田野吹来的风,清凉爽快,沁人心脾。

教师总结:社会主义市场经济是使市场在国家宏观调控下起基础性配置作用的经济,充分发挥市场基础性调节作用,就必须主要靠经济手段、法律手段,而不是行政手段。(三)课堂总结、点评这节课我们重点学习了社会主义市场经济的有关知识,知道了社会主义市场经济的基本特征,以及国家宏观调控的含义、目标和主要手段。这对于我们在经济生活中正确地认识我国市场经济的性质和作用,理解国家宏观调控的措施及意义,增强社会主义优越感和民族自强意识,自觉投身现代化建设等将有重大指导作用。★课余作业 讨论:联系经济生活中国家宏观调控的实例,讨论应如何认识和理解国家各种宏观调控手段的综合运用,对国民经济发展的意义。★教学体会 本节内容与学生生活实际联系密切,在学习中应该多引入日常生产、生活中常见的一些宏观调控实例,让学生去深刻理解、把握宏观调控手段及其作用。
预设 大困难是由小困难组成的,小困难是不难战胜的,一步一步战胜了小困难,最后就能战胜大的困难。当然,重要的还在于走好每一步,一步一步坚持不懈地走下去。在人生道路上,面对困难,“走一步,再走一步”这种人生经验,给人以战胜一切艰难险阻的信心。结束语:古语说得好,“宝剑锋从磨砺出,梅花香自苦寒来”。人的一生少不了经受挫折与磨难,但也正是在战胜困难的经历中,我们的人生才变得充实而有意义。当我们面对困难时,鼓起勇气,大声地对自己说:“走一步,再走一步。”【设计意图】本环节巧妙运用课文批注,引发学生思考,并引导学生结合自己的生活体验,从几个角度,开放性探讨获得的人生启示,让学生在轻松的氛围中,获得启示,启迪他们在生活中去运用这些人生经验,战胜困难。
【教学提示】题目的设计意图是要培养同学们患难与共的爱心,克服困难的勇气和决心。目标导学二:分析环境和心理描写1.文章开头为什么突出“酷热”?明确:开头一自然段主要写孩子们为什么想到去爬悬崖。写天气的酷热,通过环境描写,突出了人物的心理,即酷热使人烦躁,小伙伴就厌倦了正在玩的游戏,从而想到很久没有爬悬崖。2.“时间在慢慢地过去。影子在慢慢拉长,太阳已经没在西边低矮的树梢下,夜幕开始降临。”“暮色中,第一颗星星出现在天空中,悬崖下面的地面开始变得模糊。”这两句话是什么描写?请简要分析其作用。明确:这是典型的环境描写,很好地烘托了“我”的恐惧心理。3.当“我”被弃于悬崖时,“我”的心理状态是怎样的?请从文中找出描写“我”处于险境中的心理状态的词句。明确:“我”的心理状态是恐惧。词语:阵阵晕眩、天旋地转、神情恍惚。句子:“我听见有人在哭泣、呻吟;我想知道那是谁,最后才意识到那就是我。”“我趴在岩石上,神情恍惚,害怕和疲劳已经让我麻木。”
1、书中还有许多描写旺达的片段,哪一处给你留下了深刻的印象呢?请同座位互相交流。全班交流。老师也想和大家一起分享一点感受。老师读第13页片段,并谈感受。课件出示:孤单,被嘲笑者2、你有过被人嘲笑的经历吗?谈一谈。旺达是怎样面对同学们的嘲笑?3、转学之后,十三班的同学们收到了她爸爸的来信。谁愿意读读这封信?圣诞节来临之际,旺达也写来一封信。学生读。读完这两封信,大家肯定感慨万千,一定有很多话想说吧?全班交流课件出示:善良 宽容
二、为什么要学习?(插入学习歌)有一首歌这样唱:中国有一句话,活到老,学到老,该学的真不少,书里书外都重要。(多媒体)古人荀子有言:不积跬步,无以至千里;不积小流,无以成江海。伟人毛泽东说:一天不学习,赶不上刘少奇今人说终身学习,学习能增进智慧,使人睿智。人生无坦途,跋涉多风雨,畏惧时,智慧是一柄利剑,助你披荆斩棘,笑傲人生;迷茫时,智慧是一盏明灯,为你点亮心灵,坚定方向;疲乏时,智慧是一弯山泉,让你洗去尘埃,净化心灵。

4.操作。(“做一做”第2题) 全班同学动手操作,1名同学到投影仪上操作。 (1)第1行摆5个△,在△下面摆○,△要比○多1个。第2行摆几个○? (2)第1行摆4朵红花,摆的黄花比红花少1朵,第2行摆几朵黄花? 二、运用新知 教科书练习一第1~4题。 1.第1题:左图是猴子多,右图是骨头多。(避免学生产生思维定势) 2.第2题:学生观察,看到公鸡和鸭子虽然摆的一样长,但疏密不同,进而判断摆的密的鸭子的只数多些,而公鸡只数少些。 3.第3题:学生在观察到第一排蛋糕同样多的基础上,只需比较两盒中的第二排。第二排多的就多些,反之,就少些。 4.第4题:此题是在同一排中比较多少,当第5次循环出现珠子时,只出现了一个黄色珠子,所以黄珠子多而红珠子少。 三、总结 教师:今天我们学习了“比一比”,知道在比较时,一定要一个对着一个比,就会得到正确的结果。

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.

The theme of the reading and thinking is about “Understanding how a problem was solved”.The Listening & Speaking & Talking is about international co-work to protect the Mount Tai, in which the students from seven countries came up with many solutions even create the Mount Tai App. This section aims at showing how to solve a difficult and even tough problem about protecting the cultural heritage by the international co-work.

But the proposal led to protests because it would destroy a lot of cultural relics. The Egyptian had no choice but ask the UN for help. Therefore, a international cooperation about how to protect the cultural relics began, which involved the time length about 20 years and a large amount of fund. Then, the problems was solved. 1.
