初中英语第三册Unit6说课教案

一、教学前的思考

（一） 教材分析

新编初三英语教材继续保持第一、第二册的编写特点：

1.以学生的发民为宗旨,在学习的基础上了解文化差异,发展健全的人格,培养合作精神和社会公德意识.如本单元通过对海底世界的了解,要求学生从占滴小事做起,保护动物,保护海洋,保护环境,拯救地球.

2.教科书所设计的语言情景,尽可能地反映学生的现实生活,紧扣时代的发展.如本单元Lesson24中教学学生能上网,上图书馆查询资料.

3.教科书以单元为基础安排教学内容,每一个单元以话题为中心,通过任务设计(task.based)的形式,开展听,说,读.写的训练,强调节器对语言的实际运用.本单元的话题是Nature-----sea.

（二）教学内容分析

本单元为期中复习单元,具体教学内容为：

Lesson21由Ask and answer,Puzzle dialogues, Read and act三部分组成，重点复习现在完成时，并时行多种时态的比较复习。

Lesson22由Pre-read,Group work三部分组成，通理介绍地球卫士，环保之父Jacques Cousteau在海洋探险，海洋保护等多项事业上为人类做出的贡献，使学生装在了解美丽的海底世界的基础上，更加自觉地投身到热学自然，保护环境的行动上去。

Lesson23在前一课的基础上自然地引出两项与海洋有关的运动——潜水和冲浪，通不定期Read and say,激发学生热学运动，热爱生命。

Lesson24安排了Look and role-play，向学生介绍两种查寻资料的方法；然后可求学生查找有关shark的资料。这一环节自然地过渡到Read­­­­­——学习有关鲨鱼的知识，从而进一步热爱大自然。通不定期第二部分的Ask and answer,复习宾语从名用法。课文最后部分安排了三幅动物（海豚，老虎，鹿）的图片，正好可以锻炼学生课后通不定期查找资料解决写作的问题。本课还安排了一则听力训练。

本单元是围绕复习内容编写的。教师在指导学生学习时，应让学生明确学习班要达到的目的，让他们有意识地整理所学的知识，发展自已的能力。为此，我们认为单元重点是：

1．复习现在完成时

a.重点复习现在完成时的一般疑问句和特殊疑问句，同时掌握可与现在完成时态相连接的时间状语形式；

b. 综合复习一般过去时和现在完成时，明白两种时态表达的侧重有所不同；

c.要求正确运用时态，句子结构正确，能针对问题作回答。能区别have/has been(to)与have/has gone(to)的含义，并正确运用。

2．复习宾语从句

a．宾语从句的语序问题；

b．宾语从句的时态问题；

c．宾语从句的人称问题；

单元难点

1．宾语从句时态的呼应以及语序问题；

2．正确运用一般过去时和现在完成时。

二、教学目标定位

（一）语言知识

由于本单元是复习单元，其中出现的生词不多。学生通过本单元的学习应理解并正确运用以下单词和句型。

（二）言语技能

１．通不定期一系列的听力训练，ＶＣＤ的欣赏，提高学生听的能力。

３．在语庋复习中，创设情景，以多种task激发学生说的欲望，培养学生的言语交际能力。
