    人教版高中语文必修2《直面挫折学习描写》教案2篇

    《贫寒是福天道酬勤石智勇从挫折中奋起》也许是自幼的贫寒生活塑造了石智勇内向的性格,即使是胸挂金灿灿的奖牌接受全场观众欢呼,他的表情也是略显羞涩的。小时候吃不饱肚皮的经历让他至今在“最喜欢的东西”一栏还填写着“食物”二字,而“穷人的孩子早当家”的坚韧,却又是促成他今日辉煌的动力。中国举重队副总教练陈文斌赛后说道:“智勇这几年练得很苦,今天终于有了这样的成绩,这是天道酬勤的结果。石智勇的奥运会金牌是中国男举的一次突破,我们非常激动。”在希腊神话里,命运女神总是让英雄历经磨难。石智勇也不例外。四年前的悉尼奥运会前夕,他在一次训练中扭伤脚踝,失去了参赛机会。“当时我伤心极了,不敢看电视直播,我怕参赛的选手成绩太低了。高点我还好一点,自欺欺人一下说,哎呀好高,自己去了也拿不了冠军,要是低了,自己没去,失去冠军机会,心里痛啊。后来结果出来,也不怎么高,心里真难受。”

    人教版高中语文必修3《学会宽容 学习选择和使用论据》教案2篇

    评价分析法,就是引述事例后,对所引述的事例作适当的评价,从而使自己的观点得到印证。例如,在论“节俭”时,引用了“曾国藩以俭戒子,其子曾纪泽终成出色的外交家;方志敏居官不贪,一生清贫,千古留名”的事实后,接着进行分析:是的,“俭者心常富”,节俭能培养人同困难作斗争的勇气和意志,而这正是一个人立业最重要的素质。从这个意义上说,有人说饥饿是人生的佐料,吃苦是一种资本也不无道理,而自觉和戒奢尚俭则更是促人修身养性,磨炼意志的有效途径。这里,作者紧扣论点,对论据进行了评价性分析,这种评价分析使作者的观点得到强化。(四)因果分析法因果分析法,就是抓住论据所述的事实,并据此推求形成原因的一种分析方法。事出必有其因。我们可以依据事物发展变化的因果关系,由事物发展变化的结果,推导出产生这种结果的原因,从而揭示出一定的生活规律,使事例有力地证明观点。

    人教版高中语文必修3《善待生命 学习论证》教案2篇

    论证方法之引证法如何用好引证法:1.所引用的名言警句等针对性要强。每句名言都产生于特定的背景,都应用于特定的交际目的,即使谈同一个问题,也有不少名言可供选取。2.要简洁,不宜过多。议论是在发表自己的见解而不是在介绍他人的见解。引用他人的话,目的是为了让读者更加信服自己的话。3.要注意直接引用和间接引用的区别。直接引用务求文字、甚至标点均准确无误;间接引用只须述其大意,但要注意人称的转换。论证方法之喻证法喻证法是用设喻来论证论点的方法。在议论文中,设喻可以使论点更易懂、更风趣、更容易获得读者的认同。喻证法能化抽象为具体、化艰深为浅显、化枯燥为生动。论证方法之喻证法如何用好喻证法:1.以小见大,就近取譬。要精选生活中细小的、人们熟悉的事物做为设喻的喻体。2.喻体不求形似,只求神似。做为喻证的喻体与做为比喻的喻体不同。比喻的喻体是为了强调特征,描绘事物,侧重形似,以形比形;而喻证的喻体是为了阐发观点,以正视听,力求神似,以义取形。

She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes.

From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him.

The story was quite successful in achieving its purpose, and I liked it because it had a clear moral.However, while the moral of the story is clear, the actions of the king seemed pointless to me, because none of the characters in the story learnt anything.
