  • 人教版高中语文必修5《逍遥游》教案

    六、到此为止,我们了解到,作者对“笑”鲲鹏和别人的蜩与学鸠、斥鴳、宋荣子都一一作了否定。那么请大家讨论一下,1、作者对鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”是不是肯定呢?明确:也都作了否定。否定后者好理解,关键是否定前者不好理解,因为“鲲鹏展翅”早已作为积极的意象被人们广泛引用。但在本文中,作者在讲述这一寓言故事时,突出的不是鲲鹏本身,而是风力,“故九万里,风斯在下矣,而后乃今培风;背负青天,而莫之夭阏者,而后乃今将图南”。对风力作用的突出,实际上就是对鲲鹏的否定。作者写了“笑”的双方,对“笑”的一方蜩与学鸠、斥鴳、宋荣子都作了否定,对被“笑”的一方鲲鹏和“知效一官,行比一乡,德合一君,而征一国者”也都作了否定,并且对顺便提及的野马、尘埃、芥、大舟、朝菌、蟪蛄、冥灵、大椿、彭祖、列子等事物或者人物也都作了否定。这种全盘否定的态度,如果我们借用本文中的一个形象的词语,可以说是:笑!是的,本文也可以说是:庄子“笑”万物!

  • 人教版高中语文必修4《苏武传》教案

    二、课堂教学:1、学生简介背景:教师掌握:汉武帝开始对匈奴进行长期的讨伐战争,其中取得了三次具有决定意义的胜利,时间为公元前127年、前121年、前119年。匈奴的威势大大削弱之后,表示愿意与汉讲和,但双方矛盾还是根深蒂固。所以,到公元前100年,苏武出使匈奴时,却被扣留,并迫使他投降。《苏武传》集中叙写了苏武出使匈奴被扣留期间的事迹,热烈颂扬了他在敌人面前富贵不能淫,贫贱不能移,威武不能屈,饥寒压不倒,私情无所动的浩然正气,充分肯定了他坚毅忠贞,大义凛然,视死如归的民族气节。2、作者介绍:班固(32——92年),字孟坚,扶风安陵(今陕西咸阳市东)人。东汉著名的史学家。《后汉书·班固传》称他“年九岁,能属文,诵诗赋。及长,遂博贯载籍,九流百家之言,无不穷究。所学无常师,不为章句,举大义而已”。其父班彪曾续司马迁《史记》作《史记后传》,未成而故。

    ③于是,大自然出现了惊人的奇迹,不毛的石缝间丛生出倔强的生命。④或者就只是一簇一簇无名的野草,春绿秋黄。岁岁枯荣。它们只有三两片长长的细瘦的薄叶,那细微的叶脉,告知你生存该是多么艰难;更有的。它们就在一簇一簇瘦叶下自己生长出根须,只为了少向母体吮吸一点乳汁,便自去寻找那不易被觉察到的石缝。这就是生命,如果这是一种本能,那么它正说明生命的本能是多么尊贵,生命有权自认为辉煌壮丽,生机竟是这样地不可扼制。⑤或者就是一团一团小小的山花,大多又都是那苦苦的蒲公英。它们不似田野上的同宗长得那样茁壮,它们的茎显得坚韧而苍老。它们的叶因枯萎而失却光泽。它们已经不能再去为人们作佐餐的鲜嫩的野菜,却默默地为攀登山路的人准备了一个可靠的抓手。生命就这样地被环境规定着,又被环境改变着,适者生存的规律尽管无情。但一切适者就是战胜环境的强者。生命现象告诉你,生命就是拼搏。

  • 人教版高中语文必修4《柳永词两首》教案

    (一)上片:描写杭州的自然风光和都市的繁华“东南形胜,三吴都会,钱塘自古繁华”,“东南形胜”,是从地理条件、自然条件着笔写的。杭州地处东南,地理位置很重要,风景很优美,故曰:“形胜”。“三吴都会”,是从社会条件着笔写的。它是三吴地区的重要都市,那里人众荟萃,财货聚集,故曰:“都会”。“钱塘自古繁华”,这一句是对前两句的总结,因为杭州具有这些特殊条件,所以“自古繁华”。下面就对“形胜”、“都会”和“自古繁华”进行铺叙。“烟柳画桥,风帘翠幕,参差十万人家”是对“三吴都会”的展开描写。“云树绕堤沙。怒涛卷霜雪,天堑无涯”是对“东南形胜”的展开描写。这里选择了钱塘江岸和江潮两种景物来写。“市列珠玑,户盈罗绮,竞豪奢”是对“钱塘自古繁华”的展开描写。描写了两个方面:一是商业贸易情况——“市列珠玑”,只用市场上的珍宝,代表了商业的丰富、商业的繁荣;二是衣着情况——“户盈罗绮”,家家披罗着锦。“竞豪奢”,又总括杭州的种种繁华景象。

  • 人教版高中历史必修2古代手工业的进步教案

    ①原因:封建制度的衰落(根本原因)【合作探究】清朝资本主义萌芽缓慢发展的原因。提示:①封建所有制的束缚。残酷的封建剥削使农民赤贫如洗,无力购买手工业品,限制了手工业产品的销路。封建地租的剥削率很高,又驱使地主和商人把他们的钱财用于购买土地,影响资本主义手工业的扩大再生产。②.封建政府的压制。清政府实行重农抑商的政策,采取了许多妨碍手工业生产和资本主义萌芽发展的措施,主要的有:实行闭关政策,严格限制海外贸易;在国内广设关卡,对商品征收重税;严格控制手工业的生产规模,如建立受官府控制的行会,制定行规限制雇工人数、产品品种、控制原料分配,限制产品销售的价格和地区范围等。②发展的表现:具有资本主义萌芽的部门和地区增多。(参见教材P10“学思之窗”)

  • 人教版高中历史必修2开辟新航路教案

    材料五航路开辟后,东方香料输入欧洲的总量较中古之时猛增30倍,而胡椒、丁香等在印度购入和在英国卖出的差价亦高达10至29倍,其他货物的获利同样惊人。这一时期,新的商品不断涌现,特别值得注意的是美洲的特产——玉米、马铃薯、烟草、可可等——被传播到欧亚大陆。这时,世界性的对外贸易主要通过大西洋,地中海与意大利皆告衰落,而沿大洋的英、荷等渐居中心。到17世纪时,英国的伦敦与荷兰的阿姆斯特丹成为世界贸易中心。问题4:材料五表明,新航路开辟后对世界贸易产生了哪些重大影响?答案4:结束了世界相对孤立状态;各地文明开始会合交流,日益连成一个整体;欧洲商人直接同世界各地建立商业联系;促进不同国家和贸易的发展,促进世界市场雏形开始出现。

  • 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

    【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罗斯福新政教案

    【教学参考】对“新政”作用的评价史学界对“新政”作用的评价是仁者见仁、智者见智,但基本上有三种观点,即“功大于过论”、“过大于功论”和“功过参半论”。持“功大于过论”者认为“新政”在美国历史上基本上是一种进步现象,首先,“新政”挽救了危机,使美国人民摆脱了危机的困苦局面;其次,在缺少足够的宏观经济政策知识的时代,罗斯福所做的努力确实是开创性的;再次,罗斯福“新政”开启了美国以后历届政府实施国家干预政策的大门,成为缓解自由主义经济制度之弊病的一剂良方,并在实质上加强了美国联邦政府的权威;最后,在30年代资本主义世界经济危机的背景下,同日本、德国为转嫁危机而发动战争的策略相比,“新政”无疑代表了一种进步、民主的解救危机方式。持“过大于功论”者认为“新政”未能使美国走出萧条、步入繁荣。
