Unit4 Lesson21 优质课教案 一、Analysis of teaching materials 这是第四单元第三课阅读课，围绕books or computers 展开话题。阅读是一个单元语言输入较为集中的环节，阅读中的教学活动主要围绕阅读材料本身的内容展开。阅读后的活动旨在让学生通过完成问题、辩论和语言难点的学习等形式进一步加深对文章的理解。同时，通过本课阅读的学习，教育学生做一个爱读书的人，并且通过对中国古四大发明的了解，热爱我们的祖国。 二、 Analysis of students 初二学生已具备一定的英语语言表达能力，所以教师可以设计一些学生自主表达的环节，比如与本课内容有关的话题讨论等，但因为学生基础稍差的实际情况，语言准确性会差些，教师要及时引导。三、Learning aims 1 Knowledge aim New words and phrases: appear, modern, electronic, sell(sold,sold), press pass on, by hand, printing press, keep on 2 Ability aim Cultivating students reading ability and using English to express themselves. 3 Emotion aim Keep on reading and know more about the history of China. 四、 Teaching and learning methods Reading instruction. 五、 Teaching process Step 1 Lead in.

(此环节需要学生再读课文，找出各个段落的中心意思，要求学生带着明确的目标再课文，以达到有的放矢地进一步理解课文的目的。) Step 4 Group work ( Fine reading) Work in groups, students need to read each paragraph more carefully.

Divide the students into two groups. Then they need to close their English books and try to finish the passage on the screen with different numbers of blanks. (此环节为精读以及输出部分，该环节要求学生把所学知识通过语言实践竞赛的方式输出，根据课文内容，挖空填词，随着挖空越来越多，难度越来越大，得分多的组获胜) Step 6 Emotion Show the students the four great inventions of ancient China and four new inventions of modern China.
