教学主题
Unit6
When
was
it
invented
(the
first
period)
一、教材分析
本单元学习的是一般过去时的被动语态，包括一般过去时的被动语态的结构和运用，是在九年级第三单元“Teenagers
should
be
allowed
to
choose
their
own
clothes”即含有情态动词的被动语态的基础上进一步学习被动语态，为以后被动语态扩展运用到不同时态中奠定基础。本单元涉及内容是本书当中比较重要的一部分。另外通过对我们熟悉经常使用的发明物的历史来开阔眼界，丰富学生的阅历，使学生养成勤于思考，善于总结的好习惯。
二、学生分析
九年级学生有较明确的学习动机和态度。本单元以发明为载体，通过各种发明和发明家激励学生求知的欲望。对刺激记忆手段多的知识记忆深刻，遵从记忆规律。大多数初中生主要通过他人评价初步形成对自己的评价，所以很在乎他人的评价。同时自我意识不断增强。因此在本课教学过程中，以任务型教学为主，通过任务和不同的评价方式，提高学生参与意识。
三、教学目标
一、 语言知识目标：1）、知识与技能目标：
掌握新词汇invent，invention,
inventor,
be
used
for，新句型When
was
it
invented
It
was
invented
in….
What’s
it
used
for
It’s
used
for
doing
something.
Who
was
it
invented
by
It
was
invented
by….提高听力水平。理解和正确运用被动语态。能谈论重要发明的历史及用途。 2）技能目标
能谈论重要发明的历史及用途，能针对各项发明的用处及特点，发表自己的看法，并说明理由。
3）情感目标
使学生懂得人类的科学发明创造了丰富的物质文明。培养学生的创造发明的能力和愿望二、教学重难点
1. 教学重点：
1) 本课时的单词、词组和句型，学习运用一般过去时态的被动语态。
2) 学会询问发明时间及用途的基本句型：
—When was the telephone invented
—I think it was invented in 1876.
—What are they used for
—They are used for seeing at night.
2. 教学难点：
运用一般过去时态的被动语态来讨论发明的发明时间及用途。
四、教学环境
息化资源：主题资源网站 常规资源：知识相关链接 教学支撑环境：多媒体；
五、信息技术应用思路（突出三个方面：使用哪些技术？在哪些教学环节如何使用这些技术？使用这些技术的预期效果是？）20
0字
1）多媒体辅助：使用自制的课件，使抽象的语言变得直观，为学生运用英语进行交际创设情景，实现师生互动，生生互动和人机互动的多向交流。2)
通过多媒体和任务的完成学生会突破难点，产生一定创造精神。
六、教学流程设计（可加行）
教学环节（如：导入、讲授、复习、训练、实验、研讨、探究、评价、建构）
教师活动
学生活动
信息技术支持（资源、方法、手段等）
