第四篇:高中英语话题作文教案

高中英语网

话题作文《成功》

一、话题导入

同学们,今天这节课,咱们来点轻松的,聊聊天,谈谈话,上一节轻松的话题作文课,怎么样?(稍事停顿,看同学们的反应,学生积极性)(今天来了这么多老师听课,。今天的话题,是大家非常熟悉也非常关心的——今天几号了?(同学们答3月17日),相信同学们目前最大的心愿就是高考成功。好,咱们就来聊与成功有关的话题,

二、作文开讲

(读慢点,注重停顿和语气) 有位老这不算什么,还有大学呢;你大这不算什么,你还没有参加工作呢;你参加工作谋了你有了好位置,不一定就能扮好你的社会角色。只有你用自己的学识、聪明、勇气和毅力赢得了社会财富,你才算成功了,但这也不是最后的成功。

这位老师对一名学习成绩差的同学说:你小学没考上第一名,这

高中英语网

不要紧,还有中学呢;中学没考上第一名,这不要紧,还有大学呢;大学没考上第一名,这不要紧,你将来还要走上社会呢;参加工作了,没有谋个好工作,这不要紧,你还可以寻找;一时寻找不到,这也不要紧,尝试着做几件事,你就会对自己有所发现。你一直没有成功,这不要紧,或许这是件好事,这反倒使你一直保持一种冷静、。同学们对这个话题有了初步的理解,话题作文的由头——“成功”(板书:成功,字写大一点,居中)

1(选材)

绝大多数同学对话题作文的理解仍然停留在材料作文上,不自觉地被材料暗示的中心所左右,以至于写出的作文千人一面,观点雷同,没有多少新意,这是当前的通病。因此,我在这里需要非凡强调一下话题作文与传统的材料作文的区别。所谓“话题”,就是谈话的中心,就是引发谈话的由头。由某个设想好的“话题”所引

高中英语网

出的作文就是“话题作文”。也可以这样理解:话题好比一个圆的圆心,从圆心到圆周上的任何一点连起来的线都可视为一个话题作文的写作角度。而与此相对的材料作文的主题则必须从材料中提炼,行文也必须依循“引议联结”的模式,具有很强的限制性。话题“成功”的选材朋友的成功,可以写成功的感受等。(请3有把握的,有话可写)题选材,题范围,章来。如话题作文“呼唤”实在有偏题的嫌疑。

如何熟悉成功?[成功是什么(宏观、抽象)],1、话题中的两种成功观,让学生找出来,即文中加横线的部分。2、现代汉语词典解释:成功就是预期目标的顺利实现。3、闻名乒乓球运动员李楠的成功观:“成功是努力的过程,是自己所钟爱的事业的不断进步,是

高中英语网

自己能够为自己爱的人和爱自己的人带来欢乐,是留在人生路上坚实而干净的脚印。”4、自己(曾岚)的成功观:成功是什么?是我们生命中想达到我们的目标而奋斗的过程,是一条线,而不是一点。5、其他(同学们的立意)[成功是什么(微观、具体)]1、每个人都有自己不同的成功观点,可以分三类。一类:他们获得到一世的功名,他们心中装自己的同时心中容着天下人的成功。1在于征服,在于从士兵到将军的过程。2世界的人都用我的视窗系统。二类:只因他们心中惟有自己没有天下人。1高境界的实施。2三类:天。12、教师说:成功3、清洁工说:成功是天天早晨给人们不多

3、取一个吸引人的标题。(题目)

作文题目其实好比人的衣裳,就象报纸的标题一样,往往起到抢眼的作用,有很多同学不重视,相当一部分同学是作文写完了之后才草草地拟一个标题,有时候甚至忘记了,没有标题,这是一个误区,

高中英语网

要吃很大的亏。高考阅卷老师平均两三分钟就改完一篇作文,标题的映象对于他给你的分值太重要了。因此,在构思文章的时候,把精力多用一点在题目上是十分关键和重要的。就成功话题作文而言,可以考虑拟如下题目,大家一起来比较筛选。一种方法是给话题前面或后想,一名高三学生的成功观,作文内容或中心的体现。如(我们一定会做的更好wWw.hAowOrD.CoM),让我捧走等

4、写自己最擅长的文体(形式)

论文

三、布置作业

完成“成功” 提示:根据刚才对选材、审题、立筛选,确定自己熟悉的一个角完成整篇文章,当然成文时还要注重布局某篇板书设计(略)

附:话题作文材料 高中英语有位老师对一名学习成绩优秀的同学说:你在小学考第一名,这不算什么,还有中学呢;你在中学考了第一名,这不算什么,还有大学呢;你大学考了第一名,这不算什么,你还没

高中英语网

有参加工作呢;你参加工作谋了个好差事,这也不算什么,有了好差事,你并不一定就有了好位置;你有了好位置,不一定就能扮好你的社会角色。只有你用自己的学识、聪明、勇气和毅力赢得了社会财富,你才算成功了,但这也不是最后的成功。这位老师对一名学习成绩差的同学说:你小学没考上第一名,这不要紧,你还可以寻找;一时寻找不到,这也不要紧,你就世上本来就没有最后成功的归宿。
