Ⅰ.Materialanalysis
本课是九年级第四单元第三话题的第三课时。
主活动是1a和2。
1a介绍了电脑在各行各业中的作用，也提醒了学生要合理地利用电脑和网络。
在这个信息爆炸的时代，学生很容易迷失方向，辨别信息的真假尤其重要。
1b既可以通过提纲式结构来巩固1a的内容，也可以让学生学习在写作中运用这种方法来草拟提纲。
2这个写作任务，可以让学生充分发挥想象，如果没有了电脑，生活会变成什么样子。
这从另一个角度让学生感受电脑对我们生活的重大影响。
为了能让学生有足够的时间来完成这个任务，建议留作家庭作业。
Ⅱ.Teachingaims
1.Knowledgeaims：
掌握本课的重点词汇和短语，继续学习定语从句。

不要担心没有解决新词就让学生完成任务。
其实1b就是文章的大意。
就是要培养学生获取信息的能力。
另外要学生注意表示举例子的词语：

S7:

对于文章末尾出现的新形式的定语从句，老师可以提一下。
并指出关系代词“that”被省略了，因为它在从句中作宾语。
当学生找出新词后，老师要按照构词法、近义词或反义词来归类让学生学习。
对于本课内的词组辨析，不一定都要在本次课内解决，也可以放一点在讲解作业时处理。
如：
forexample和forinstance,besides和except。
