人教版高二英语选修八InventorsandinventionsReadingtheproblemofthesnakes教学设计

教学设计：
本课教学内容为为人教版选修8第三单元阅读课The Problem of the Snakes，讲述的是一女孩儿如何通过多次尝试，最后成功地把在他母亲家院子里安家的一窝蛇捉住并放归大自然的，他的捕蛇技术也申请了发明专利；文章也提到了申请专利的标准。

文章篇幅较长，内容与学生生活实际不是特别密切。

基于上述分析，本节课的教学设计思路从体裁，思维培养，语言和文本处理四个层面入手。

1．从体裁层面：此文章为故事性的科技文，故事性较强，因此时间线索贯穿始终，因此文章梳理时抓住这一主线，将主要信息进行提炼和理解，让学生对前因后果
有个纵向的掌握；而且文章主题升华围绕科技对人类的影响进行适度的引导。

2．从思维培养层面：既然是科技文，因此文章的逻辑性和条理性极强。

所以在处理文章内容时，将充分利用各种thinking map 即思维导图归纳，整理和输出主要信
息，以帮助学生建立和运用一些初级的逻辑思维。

3．从语言层面：本课文的语言本身不是很难，但是作为科技文，其语言表达准确，逻辑严谨，因此将通过对部分重点词句的解读，让学生感知这种文体特征。

4．从文本处理层面：此文本篇幅较长，就一节课无法面面俱到，因此根据本节课的核心任务或者out-put的需要，着重处理文章前半段，即捕蛇的环节，申请专利环
节有涉及，但是不强调，以做到重点突出。

二．教学目标
1．通过Thinking map 的方法，进行文章信息的解读，梳理以及输出；
2．对部分词句进行重点解读，学习（故事性）科技文的逻辑和语言特征。

3．联系生活中的小发明和人类史上伟大的发明家，感知科技对人类生活的影响。
