高一英语必修二第三单元课件
一、教材内容分析及要求
本单元的听说读写活动围绕中心话题“计算机”展开，内容涉及计算机的发展历史计算机的应用等，其中还谈到计算机在内的几种信息技术的载体、智能机器人的发明等等。
话题虽然有趣。但所选语言材料属于科普类说明文，内容教为抽象，文章中也不乏一些专业术语，有一定的难度。不过整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章读起来浅显易懂。整个单元要求掌握：
1．了解计算机的发展历程及其在社会的广泛运用
2．能用英语表达自己的观点并进行简单的理由阐述和作出决定
3．能按时间顺序描述一件事情
4．了解和掌握现在完成时的被动语态
二、设计思路
本单元可鼓励学生用英语表达自己的观点并进行简单的理由和阐述。比如，我们可以通过网络来做什么？电脑对我们来说，到底意味着什么？充分利用一切手段，提高学生阅读等各项能力，设置不同的任务，放手让学生去理解，去自己找出重难点，通过讨论，自己解决问题。此外，采用由易到难设置问题来降低难度，用分解的方式来帮助学生对文章的理解。

二、漫画欣赏
画面描述
A young man is running toward the end of a race，sweating all over.The end line leaves a deep impression on us，for it is both “finish line” and “starting line” if we look at it from a different angle.
寓意理解
Achievement calls for celebration.But life is just like an endless race.An ambitious person will well realize that his success is the starting point for a new race.

三、拾缺补漏
1．辨 析 common/ordinary/usual/general/average/universal/normal
common含有经常发生或经常见到的事情，又指普通事物，但并不含有多数的意思，可用于平常的意思，常用于习惯，经验，生活，意见。ordinary意为“平常的”“普通的”“一般的”，是依照一般标准来判断，含有平淡无奇的意味。usual“平常的”“通常的”，强调习惯性，符合规章制度的或一贯如此的。general指“普通的，一般的”与particular相对；average作“普通的”讲时，强调“一般水平”；universal指“普通的”时意为“全然，没有例外”。
normal指正常的，规范的。

四、巧思妙解
1．(2008年福建卷)Nancy enjoyed herself so much________she visited her friends in Sydney last year.
that B．which C．when D．where
【解析】 句意为：去年Nancy在悉尼拜访她朋友的时候，她玩得很开心。本题是when引导的一个时间状语从句，when这里意为“当……的时候”，B、D两选项可以从句意和句子结构上加以排除。但可能有些学生会受so...that固定句型的影响，而选that，翻译成“如此……以至于”与语境不符。
【答案】 C
2．(2008年四川卷)I haven’t seen Ann for________long that I’ve forgotten what she looks like.
such B．very C．so D．too
【解析】 句意为：我有很长时间没见着安了，我已忘记她长什么样了。so/such...that如此……以致，即so＋adj./adv.＋that，而such＋n.＋that，long为副词，故用so。
【答案】 C
3．Pop music is such an important part of society________it has even influenced our language.
as B．that C．which D．where
【解析】 考查such...that “如此……以至于”结构。
【答案】 B
4．Beijing was attacked by such a terrible sandstorm________few residents had ever experienced before.
as B．which C．and it was D．that
【解析】 考查定语从句。as在此处为关系代词，作experienced的宾语。
【答案】 A
5．Jerry was so angry at all________I was doing________she walked out without a word.
A．that；which B．which；that C．what；that D．that；that
【解析】 第一个空为关系代词，引导定语从句修饰all；当先行词是all时，只能用that，而不能用which来引导定语从句。第二个为so...that结构，that引导结果状语从句。
【答案】 D
