人教版高中语文必修2《涉江采芙蓉》教案2篇
三、想象画面，把握意境1.指导想象学习陶渊明的《归园田居》我们脑海中自然会出现一幅幅的画面，比如他归家后的生活场景，我们会想象“榆柳”是如何遮蔽房屋的，而“桃李”又是如何摘种在房前的。我们会想象村落是如何在薄雾中若隐若现的，想象炊烟是如何袅袅升起的。《涉江采芙蓉》一诗只有8句话，更需要我们展开想象，去构画场景，这样才能深入诗歌，体会到诗歌的味道。2.学生想象要求学生闭目想象1分钟。3.学生展示想象结果（抽三四个学生回答即可）4.老师指导纠正学生想象不合理之处。要注意的地方：“江”可能学生会想象成小溪流、小池塘。“兰泽”可能学生理解成“湖泊”。注意字词“还顾”“漫浩浩”中隐含的情感，注意“离居”中流露的愁怨。5.时间允许的话，老师读自己的下水作文。

【教学过程】导入：如果说唐诗是中国文学史中的一朵奇葩，那孟浩然则是点缀其上的一滴晶莹露珠，其充满魅力与特色的诗风在盛唐独树一帜，也为其在人才济济的诗史上刻下了永恒的印记。同学们能否先回忆一下，我们学过的孟浩然的诗歌有哪些？（《春晓》、《宿建德江》、《望洞庭湖赠张丞相》、《过故人庄》。）我们常说"中国古诗写胸襟，是人格美的自然流露"，那么孟诗在语言和思想情感上留给你怎样的印象和感受？整体感知：本文作者闻一多先生也是一位诗人，所谓"英雄惜英雄"，相同的志向与情趣使闻一多似乎带着我们在与孟浩然进行了一场心灵的对话。那么同学们在快速阅读文章之后，能否先找出作者是选择了一个怎样的角度对孟浩然评价的？（诗如其人，人如其诗。）
人教版高中语文必修5《咬文嚼字》教案
【教学过程】第一课时一、导入新课清代唐彪在《读书作文谱》中引用武叔卿的话说：“文章有一笔写成不加点缀而工者，此神到之文，尚矣。其次须精思细改，如文章草创已定，便从头至尾—一标点。”同学们能列举出文学史上的作家哪些属于前者，哪些属于后者吗？前者有李白。后者如贾岛、王安石、欧阳修、曹雪芹等。（贾岛有关于推敲的典故。王安石修改“春风又绿江南岸”句传为佳话。欧阳修《醉翁亭记》的开头便是精心改成的。《红楼梦》更是“披阅十载，增删五次。”）提问：古今的伟大作家为什么像李白式的诗人很少，而大多数人却都要“咬文嚼字”，苦苦修改呢？这节课我们就来研究一下这个问题。二、整体感知1．快速浏览全文，熟悉主要内容。2．根据“学习重点”，确立学习目标。三、课文分析1．理清观点与材料的关系。首先，让学生找出本文在论证中所运用的材料。

方法点拨教师：有的同学叙述事实论据时，不突出重点和精华，不注意取舍，水分太多，有许多的叙述描写，有时还有详细的故事情节，文章几乎成了记叙文，使文章的论点无法得到充分的证明，这是写议论文的大忌。那么：议论文中的记叙有哪些特点？同学各抒己见。投影显示：1.议论中的记叙不是单纯的写人记事，记叙文字是为议论服务的，其目的是为作者所阐明的道理提供事实依据。所以，在记叙时要求简洁、概括，舍弃其中的细节，仅仅交代清楚事件或者人物的概貌即可，一般不在各种描写手段上下功夫，只要把能证明观点的那个部分、侧面交代清楚就行了。2.议论文中的记叙性文字不得超过总字数的1/3，否则视为文体不当。能力提升一、教师：了解了议论文中的记叙的特点，接下来我们看看今天的话题：“爱的奉献”，你想从哪个角度立论？有哪些素材？
