第四篇：30课《诗四首》教案

一、教案背景：

1、面向学生：初中，学科 ： 语文

2、课时：2

3、学生课前准备：

初读课文，认读生字词；查阅资料，明白诗作者当时的处境，为进一步体会作者的思想感情打基础。

二、教学课题：30课《诗四首》教案。

三、教材分析：

陶渊明《归园田居》一共有五首，分别以辞官场、聚亲朋、乐农事、访故友、欢夜饮，描绘了诗人丰富充实的隐居生活。本诗为其三乐农事，包含了诗人脱离仕途的那种轻松、亲近自然的那种欣悦，以及远离污浊现实的决心。世人在南山下种豆，很显然，他不善于种田，但早出晚归，不辞劳苦，在回家的路上，夕露沾湿了衣裳而他毫不在意。从表面看，写的是劳作之乐，但其内涵，是不想在污浊的现实中失去自我。

王维的《使至塞上》是一首边塞诗，唐朝时由于边境战火不断，许多诗人参加了守边高级将帅的幕府，做他们的参军、记室。这些诗人把他们在边塞上的所见所闻写成诗歌，于是边塞风光和军中生活成为盛唐诗人的新题材。这一类诗，文学史上称为“边塞诗”。

王维，盛唐著名诗人，人称“诗佛”。当时奉唐玄宗之命，赴西北边塞慰问战胜吐鲁番的河西副大使崔希逸。王维轻车简从，要到远在西北边塞的居延。经长途跋涉，在萧关遇到了骑兵，却没有遇到将官，(一问才知道)，将官此时正在燕然前线。

本课要达到的学习目标：

1、朗读背诵前两首诗

2、理解感受作者表达的思想感情

重点难点：朗读背诵前两首诗理解感受作者表达的思想感情。

四、教学方法

1、初读课文，认读生字词；利用百度搜索和多媒体，查阅资料，增长知识，培养动手能力。

2、诵读法。引导学生在反复地诵读中把握节奏，感知意境，实现心灵的探求，激发学生读诗、品诗的兴趣。

3、降级处理法，理解品评诗歌

五、教学过程：

（一）、巩固理解，解释引读。

1、《归园田居》的作者是--------，字----------，一名-----------，字----------，谥号--------------别号-----------，---------﹙朝﹚伟大诗人，少时颇有壮志，博学善文，是我国文学史上第一位----------诗人。其诗自然质朴，意味隽永。代表作有---------、------------等。

2、《使至塞上》是唐代诗人___________的作品，他与__________合称“王孟”，是唐代__________诗派的代表。

3、秽()荷锄()候骑()燕然()

4、解释下列词句中加粗的字。

晨兴理荒秽_______ 带月荷锄归_______ 但使愿无违_______ 长河落日圆______

（二）、诵读背诵，积累理解。

1、读一读：

① 教师范读，读出节奏。

读诗要读慢些，字句凝练，给人以思考的空间。读出节奏。

方法指导：五言诗句的节奏221或212，每拍的后一字遇平声可适当延长，遇仄声宜作停顿，这样朗读有抑扬顿挫的声调

2、译一译：

学生对照注释，解词析句，扫清障碍，理解诗歌内容。

3、说一说：

同学们，你觉得这两首诗中哪些诗句写得好？你能说一说理由吗？

（三）、研读品析，语言品味。

1、《归园田居》中哪一个字揭示了诗歌主旨？

2、“盛”和“稀”是两个形容词，在诗中表达了什么含义？

3、．《归园田居》中三、四句中表明时间的词是什么？诗人为何要点出时间？

4、《使至塞上》写的是什么情景内容？

5、你能说说“征蓬出汉塞，归燕人胡天”一句的含义及蕴含作者怎样的感情?

6、《使至塞上》最能体现诗中有画的是哪一联诗句，你能画画它的图景，说说它的意境吗？

7、学生画完后，通过讲评找出符合意境的加以表扬，然后利用多媒体资料，向学生展示真实的画面，并播放诗词的诵读，加强学生对诗歌诵读的韵律感。

（四）、总结。

今天，我们主要是教给大家读诗品诗的方法。读诗要：读准字音；读出节奏；读出意境；读出感情；读出个性。

继续播放多媒体资料的画面与诵读，加深印象。

六、教学反思：

教学中注意利用学生动手动脑、多媒体资料，让学生多种感官参与，体会诗歌描绘的意境，通过听老师诵读和多媒体展示，体会诗歌的韵律美，在得到美感的同时，进一步体会诗人的思想感情，达到本次教学的目标。
