Please put up your hands.Ss :respond accordingly.T: What do you usually do on your computers?Ss:Type documents/homework, listen to music, watch videos, play games, search on the Internet, send mails …T: When I were at your age, I knew nothing about computers. Most Chinese families never heard about it. However, in recent years, computers have become more and more popular, and most families in cities have one or more than one computer in their home. And some families in villages also have their own computers. Computers make life more convenient and colorful. However, it took a long time for humans to have computers that we see today. Now look at the pictures on page 17 and discuss what they have in common. Then think about Questions 2 & 3.Suggested answers:1.These pictures are all technological inventions.2.From these pictures, we know computers have experienced a long development process,and the development will never stop.3.(There may be various answers.)Step II Pre-readingPrediction: Let students predict the content of the passage according to the pictures and the title. This will involve students in active thinking and exploring.Then let them make a list of the ways computers are used today.Sample list: date processing; industrial design; learning and teaching aids; TV program editing; entertainment (watch TV/video, listen to music, play games, online chat…) communication (e-mail, e-card, instant message) …T: Now look at the inventions in activity 3. First check their meanings in your dictionaries. Then put them in the order according to the time when they appeared.Help students understand the meanings of the words: analytical, calculate and universal. Note:Universal machine is also known as Alan Turing's “universal computing machine”, is capable of computing any algorithm.Students may have different answers. They will check it after reading the passage.T: Have you put them in the right order? You will find it after reading the passage. Now turn to page 18 please.Step III ReadingSkimmingGet students read the whole passage and try to get the main idea of it.After readingT: What does “I” in the title refer to?Ss: Computer.T: What is the main idea of the passage?Ss: The passage is mainly about the history and development of computers.ScanningT: Correct! Now read the passage and finish the timeline. With this timeline, you will have a clear idea of the development of computer.Check the answers.T: The passage has three paragraphs.

Look! (on the board: simple+-ify). -ify is a suffix which means to turn into, make or become. For example, beautify. So if you know the meaning of “simple”, you can easily get the meaning of “simplify”. Who can tell me its meaning?S: To make something easier or less complicated.T: What does “it” in line 9 refer to?Ss: It refers to the fact that computer was programmed by an operator who used cards with holes.T: Why was Alan Turing called computer’s real father?S: I guess that’s because Alan made computer more powerful, which could solve any difficult mathematical problem.T: What does “this reality” in line 15 refer to?S: It refers to the reality that computer had grown as large as a room.T: In paragraph two, there are two sentences which contain the use of “so…that…” structure. Underline them and study carefully.Show the following on the screen/board:●Over time my memory has developed so much that, like an elephant, I never forgetanything I have been told!●And my memory became so large that even I couldn’t believe it!Help students sum up the form and function of this structure:Form:so + adj./adv. + that + clauseFunction:This structure is used when emphasizing the degree or amount of something by saying what the result is.Step IV DiscussionT: Discuss this question in groups: Why do many countries want to host the Olympic Games while others do not? Use the mind map below to help you. Then prepare for a class discussion. Put forward your ideas and give reasons for your choices.T: Why do many countries want to host the Olympic Games?S: Hosting the games has a major effect on the economy and brings international prestige to the country. Thousands and thousands of visitors come to the game s and the host cities are permanently improved. By planting trees and creating parks, the city becomes more attractive for tourists.S: It helps to strengthen the spirit of patriotism and also can create more job opportunities and improve the quality of employment.S: The Olympic Games is the world's largest and highest level, and most widely influential sports event. The people of all countries enhance mutual understanding and friendship and safeguarding peace in the world event. Besides, the hosting of the Olympic Games is not only a country's comprehensive strength of the comprehensive test, but also to expand a country’ influence around the world, and at the same time promote their own development as a good opportunity.T: Well done! Why do many countries don’t want to host the Olympic Games?S: Preparing for the Olympics Games is a huge undertaking. Just like the athletes, the host city spends years getting ready for the event. Before deciding which city will host the Olympic Games, the International Olympic Committee (IOC) has to examine bids from allover the world. Bidding for the games begins about ten years in advance. Without preparing a very strong bid1, a city will not win the competition to host the games.S: Hosting the Olympic Games take so long time and so much money to prepare. Building the infrastructure costs huge amounts of money. Holding the World Cup in 2002 in Japan and South Korea, for example, meant that ten new stadiums had to be built, as well as many hotels and an improved transport system. In Beijing, after winning the bid, the government began major construction projects — the extension of the underground, the improvement of the airport and the building of new motorways. Each host city must also build an Olympic village for the athletes.S: Too many visitors may do harm to the environment of the city, in addition, the venues and buildings may be wasted after the Olympic Games.T: Well done! As every coin has two sides, hosting the Olympic Games has its advantages and disadvantages. For our powerful China, it is a good opportunity to host the Olympic Games which can benefit us a lot.Step V Homework (retelling)T: Suppose you work for an information technology magazine. Write a short passage which briefly introduces the history and development of computers. Don’t write in the first person.。

人教版高中英语必修二unit3+Computers+教案4.doc

品味人生1、不管鸟的翅膀多么完美,如果不凭借空气,鸟就永远飞不到高空。

想象力是翅膀,客观实际是空气,只有两方面紧密结合,才能取得显着成绩。

2、想停下来深情地沉湎一番,怎奈行驶的船却没有铁锚;想回过头去重温旧梦,怎奈身后早已没有了归途。

因为时间的钟摆一刻也不曾停顿过,所以生命便赋予我们将在汹涌的大潮之中不停地颠簸。

3、真正痛苦的人,却在笑脸的背后,流着别人无法知道的眼泪,生活中我们笑得比谁都开心,可是当所有的人潮散去的时候,我们比谁都落寂。

4、温暖是飘飘洒洒的春雨;温暖是写在脸上的笑影;温暖是义无反顾的响应;温暖是一丝不苟的配合。

5、幸福,是一种人生的感悟,一种个人的体验。

也许,幸福是你风尘仆仆走进家门时亲切的笑脸;也许,幸福是你卧病床上百无聊赖时温馨的问候;也许,幸福是你屡遭挫折心灰意冷时劝慰的话语;也许,幸福是你历经艰辛获得成功时赞赏的掌声。

关键的是,你要有一副热爱生活的心肠,要有一个积极奋进的目标,要有一种矢志不渝的追求。

这样,你才能感受到幸福。

6、母爱是迷惘时苦口婆心的规劝;母爱是远行时一声殷切的叮咛;母爱是孤苦无助时慈祥的微笑。

7、淡淡素笺,浓浓墨韵,典雅的文字,浸染尘世情怀;悠悠岁月,袅袅茶香,别致的杯盏,盛满诗样芳华;云淡风轻,捧茗品文,灵动的音符,吟唱温馨暖语;春花秋月,红尘阡陌,放飞的思绪,漫过四季如歌。

读一段美文,品一盏香茗,听一曲琴音,拾一抹心情。

8、尘缘飞花,人去楼空,梦里花落为谁痛?顾眸流盼,几许痴缠。

把自己揉入了轮回里,忆起,在曾相逢的梦里;别离,在泪眼迷朦的花落间;心碎,在指尖的苍白中;淡落,在亘古的残梦中。

在夜莺凄凉的叹息里,让片片细腻的柔情,哽咽失语在暗夜的诗句里。

9、用不朽的“人”字支撑起来的美好风景,既有“虽体解吾犹未变兮”的执着吟哦,也有“我辈岂是蓬蒿人”的跌宕胸怀;既有“我以我血荐轩辕”的崇高追求,也有“敢教日月换新天”的豪放气魄。

33 我是一只蜜蜂,在祖国的花园里,飞来飞去,不知疲倦地为祖国酿制甘甜的蜂蜜;我是一只紫燕,在祖国的蓝天上,穿越千家万户,向祖国向人民报告春的信息;我是一滴雨点,在祖国的原野上,从天而降,滋润干渴的禾苗;我是一株青松,在祖国的边疆,傲然屹立,显示出庄严的身姿。

Unit 3 Computers I. 单元教学目标II. 目标语言III. 教材分析与教材重组1. 教材分析本单元以computers为话题,旨在通过单元教学,综合听、说、读、写等多种形式,使学生了解计算机和信息技术的产生和发展过程及其在我们的学习、工作、娱乐等生活中所起的重要作用,激发学生对信息技术的兴趣。

1.1 Warming up提供几幅与计算机有关的图片,形象地说明了计算机的发展历程,并用三个问题引发学生对这一话题的思考,从而起到热身的作用。

1.2 Pre-reading根据文章内容预设问题,检查学生对computers相关知识及应用的了解。

学生对computers的了解可能参差不齐,这更能激发学生想获取更多知识的欲望,从而引出下面的阅读文章——WHO AM I?。

1.3 Reading中以别致的标题WHO AM I?引起学生的好奇心,使学生迫不急待地阅读这篇文章,并判断出“I”是computer,从而对文章的内容印象更深刻。

文章以第一人称的形式按时间先后顺序讲述了computers的产生、发展和现状,并用拟人化的口吻表达了computers乐于为人类服务的精神。

1.4 Comprehending 1 通过scanning的方式完成反映计算机发展历程的时间进程;2 通过填表的形式帮助学生宏观梳理文章结构,找出每个段落的主题句(论点)及具体的支持性论据;3 是读后讨论,要求学生结合自己的生活实际讨论计算机如何改变了我们的生活。

1.5 Learning about language分词汇(Discovering useful words and expressions)和语法(Discovering useful structures)两大部分。

Discovering useful words and expressions 1 根据单词释义写出相对应的词汇,考查学生对WHO AM I? 文章中的重要词汇及短语的理解。

Unit 3 Computers一、整体设计思路本节课的教学设计是基于人教版New Senior English For China Student’sBook 2Unit 3 Computers Using language (Workbook) 的Listening and Speaking 部分。

授课内容是关于电脑和机器人话题的听说课,融合听说读写等综合运用语言的能力,重点突出听说能力。

在教学过程中,有目的有重点训练学生的语言应用能力,对多项语言技能的训练进行适当的整合,使其相互渗透促进。

听说读写四项技能中,读和听是输入,说和写是输出,将语言输入和语言输出有效地联系起来,从而更好地培养学生运用英语进行交际的能力。

二、教材内容分析本节课的话题是computers 和 robot,是与学生的日常生活息息相关的话题。

这一单元的话题是围绕电脑的发展以及机器人的相关知识开展的。

其中本单元中的语言运用(Using language)部分涵盖了听说读写等四项技能的运用,但因课堂时间较为有限,不能面面俱到,因此本节课的重点在于听和说这两方面。

听的部分是通过强调听力技巧,通过“听前”“听中”“听后”让学生提高听力效率,了解三则广告中三种不同机器人的信息。

说的部分是在一定的情境下,通过学生小组合作编对话的形式为自己的家庭选择一款适合的机器人并表明原因。

三、学生情况分析作为高一的学生,对电脑和机器人方面的知识应该已经有所了解和熟悉,也具备些相关的词汇和表达,而且这个话题也是学生所较感兴趣的话题之一。

但是,很多同学对于听说是存在畏惧感的,特别是高考对于英语综合能力的考察日益增强。

语音是否准确,语速是否流畅,是否能听懂信息进行问答,能否及时记录关键信息点进行语言输出等等这些情况都是我们老师在听说课活动中要考虑到的实际问题。

同时,还有些学生缺乏自信,不愿开口,担心出错等等,那么教师所设计的活动要求就要由浅入深,层层递进,逐步培养和提高学生运用英语进行表达的言语能力。
