英语必修2 Unit 3中阅读部分Who am I?的说课稿一 教材分析1 阅读教学历来是高中英语教学的重头戏，阅读教学肩负着对学生阅读技巧和方法培养的重任。Who am I?这篇文章以第一人称的手发介绍了计算机发展演变的历史和计算机在各个领域的应用，其主旨是表达计算机的发展变化之快以及在生活中的用途之广。2 教学目标语言目标单词和短语 ：simplify;sum;operator;logically;solve;reality;personal;tubes;totally;network;application;finance;mobile;rocket;explore;anyhow;goals;happiness; Technological revolution;artifical intelligence;from then on;as a result; 重点句子:Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.As time went by,I was made smaller.能力目标a.通过预测及找每段的主题句，提高（fast-reading）的能力，掌握大意。b.通过列出计算机发展演变的几个阶段，提高（carefull-reading）的能力。c.通过找文章的的主题句和支持论据，培养篇章分析和总结概括能力。情感目标感受计算机发展变化之快，明白网上交友的好与坏，学会合理运用网络资源。3 教学的重难点：重点：掌握文章的脉络，大意及相关细节信息；理解文章的结构，竖立合理运用网络资源的意识。难点：理解文章的篇章结构；二 学生情况分析 本班41个学生，其中三分之二都是男生。他们对于英语学习的积极性和参与英语课堂的主动性不高。对于信息容量大的阅读课，多数学生都有一种惧怕心里。不过对于IT这个和现实生活联系很强的中心话题，学生很感兴趣。因此，我阅读课的阅读设计都本着能调动大多数学生的积极参与为原则。三 教材处理让学生看课本上的图片，主要是提起学生课堂参与的积极性。让学生先读和记文章中黑体的单词并快速写下中文意思。把学生分成小组，让他们相互帮助完成相关的阅读任务。让学生带着相关的阅读任务去读文章。播放课本录音，让学生边听边检查自己的答案。师生互动核对答案。 四教法分析依据新课程标准的理念要求，结合本班的实际，为达成上述的教学目标；本着以学生为主的原则，我主要才用了任务型教学法，整提教学法和交际法。五教学过程Step1. lead-in ( pre-reading ) 1+5minutes Ask students to look at the picture on page17and the title of the reading passage.
