2019-2020年九年级英语全册《Unit 9 When was it invented-电视的发明》文章素材 人教新目标版
2019-2020年九年级英语全册《Unit 9 When was it invented-电视的发明》文章素材人教新目标版约翰·洛吉·贝尔德是英国电器工程师,研制电视的先驱。
他出生在苏格兰海伦斯堡一个牧师的家里,从小就表现出一个发明家的天才。
贝尔德曾就读于格拉斯哥大学及皇家技术学院。
第一次世界大战期间,贝尔德表示自己不适合去军队服役,成了一家大电力公司的负责人。
1924年,贝尔德首次用收集到的旧收音器材、霓虹灯管、扫描盘、电热棒和可以间断发电的磁波灯和光电管等,做了一连串试验来传送图像。
然而这些试验材料实在太破旧了,以致每次试验都要损坏、更新一些零件。
经过上百次的试验后,贝尔德总结了大量的经验。
1925年10月2日清晨,当贝尔德再一次发动起房间里的机器时,随著马达转速的增加,他终于从另一个房间的映射接收机里,清晰地收到了比尔──一个表演用的玩偶的脸。
贝尔德兴奋异常,他多年的梦想──发明“电视”实现了。
虽然还谈不到完美,但却是一次成功的试验。
紧接著,贝尔德说服富有的公司老板戈登·塞尔弗里奇为他提供赞助,更加专心地研究起电视来。
1926年1月,贝尔德发明的机器有了明显的改善。
他立刻给英国科学普及学会写了一封信,请求该会实地观察。
当贝尔德从一个房间把比尔的脸和其他人的脸传送到另一个房间时,应邀前来的专家们一致认为,这是一件难以置信的伟大发明。
赞助者也很快意识到了这项发明的市场前景是广阔的,于是纷纷投资,成立了好几家公司。
1928年春,贝尔德研制出彩色立体电视机,成功地把图像传送到大西洋彼岸,成为卫星电视的前奏。
一个月后,他又把电波传送到贝伦卡里号邮轮,使所有的乘客都十分激动和惊讶。
这一时期的贝尔德,正可谓春风得意,与同时代的其他几个也在发明电视的发明家相比,他的技术脱颖而出,□驾在其他发明家之上。
然而好景不长,1936年贝尔德遇到了强有力的竞争对手──电气和乐器工业公司发明了全电子系统的电视。

I will play a cartoon called “music food” My favorite food is in it. Try to guess what it is.Every time when they give a guess, I will express my like and dislike by using some adjectives like sweet, crispy, salty, sour . Make sure they know the meanings of them. For example:S:ChocolateT: It’s very crispy, but it’s too sweet. I don’t like it Can you guess the meaning of ‘crispy’? It describes food that is hard .dry and easily broken.S :Milk.T:I prefer sour milk to milk. Do you know ‘sour’? Oranges sometimes taste sour.S: Fish.T: yes! Fish is my favorite, and I especially like salty fish that is sprinkled with a lot of salt.During this course, write down the new words on the blackboard..Finally play a leading role to read them.(Purpose :To arouse the students’ interest ,create useful situations for them to learn the new words. Prepare for the next step. )Step 3 PracticeTask One writing1a.Show four food pictures on the screen and get the students to describe how the food tastes and write them down.them to list the words of the food that has different tastes according to the headings on the screen as many as possible .sweet crispy salty sourThe teacher moves around the classroom to provide help for the students who have trouble in spelling some hard words and choose three students who write different words from one another.(Purpose: To practice using the target words and review the food words they have learnt before.)Task Two Speaking and actingGet the three students to the front, divide the class into four groups:Sweet Group , Crispy Group, Salty Group , Sour GroupGame begins: The three students read their words loudly in class one by one without repetition, the group members should stand up as soon as they hear a word that belongs to them. Call out the students who stood up by mistake and have them guess the meaning of ‘by mistake’.(Purpose: This is employed to show the words they wrote and link the target words with the food words, and get the whole class moving.)Step 4 PresentationT: Just now you mentioned many kinds of food, but do you know there are some interesting stories behind them. Here is one.Ask the students to look at the picture in 2a and imagine what they are talking about.S: They are talking about the story of potato chips.T: Right .Maybe on the bag it says the invention of them!(Purpose: Cultivate their ability of imagination and present the invention of potato chips.)Step5 PracticeTask One Listening and understanding2a.

Check the answers.(Purpose: To provide practice in listening and understanding the target language in spoken conversation.)Task Two Listening and writing2b. Before playing the recording, get the students to try to give answers by memory, or just by guessing. After a while, play the recording for them to fill in the missing words they hear.

And ask your parent to sign his/her name on your book.(Purpose: The new type of homework is employed to relate the knowledge that they learn from this lesson with the life realities, and achieve the moral aims.)Blackboard design:(Purpose: To show the language structures they mainly learn from this lesson.)Part 4 Teaching reflectionAccording to << English Course Standard >>,I combine different language structures and functions with different studying tasks. I put emphasis on raising the students’ interest, forming effective strategies and developing the cooperative spirit. And I thin k I’ll make it.This is a period of various contents, maybe the time of one class is not enough, I need to adjust the teaching steps according to the actual situations. And in 1b. of Step3,it requires the teacher to have a large vocabulary to provide help for students. One minute in class, ten years’ hard working after class—I need to hold on to studying to improve myself.。

When was the telephone invented?
It was invented in 1876.
What was it used for?
It was used for talking to people in other places.
难点:when引导被动语态一般过去时的特殊疑问句的结构及用法。
二、学习分析
苏霍姆林斯基认为:“教给学生方法比教给学生知识更重要。
”建构主义是近年来介绍到我国的一种新兴教育理论,它认为知识不是通过教师传授得到,而是学习者在一定的情境即社会文化背景下,借助学习过程中其他人(包括教师和学习伙伴)的帮助,利用必要的学习资料,通过意义建构的方式获得的。
基于这样的认识,结合本课内容和初三年级学生的特点及学习经历,在教学中我侧重指导学生采用以下三种
学习方法:
1.合作学习法。
合作意识和合作能力是社会的需要,也是学习本身的需要,它有利于培养主动学习过程的合作性,以弥补独立学习之不足,增进学生之间情感沟通与智力互补。
学生通过对所学内容进行讨论,刺激学生的交流欲望,达到相互启发,加深理解,提高课堂学习效率的目的。
2.情景交际法。
即学生通过交际活动理解和运用语言知识,用所学到的知识进行对话表演、问答,从而达到脱口而出的交流目的。
3.联想法。
看图联想,营造真实的语言运用氛围,以最佳的情景和语言效果刺激学生的感官引发学生联想,激活学生的思维和想象,达到发散创新的目的。
三、教法分析
根据这节课的教学内容以及学生的实际,从培养学生能力和发挥学生主体作用的角度出发,我采用“技能训练一生生互动一师生互动”教学模式。
这种模式便于充分发挥教师的主导作用和学生的主体作用,能增强课堂教学的实效性。
采用情境教学法和功能交际法。
(采用这两种方法的目的旨在)优化教学过程,通过布置任务“最有用的发明”,让学生在课前根据自己的兴趣,通过上网、查看书籍等形式,查找自己认为最有用的发明物的资料,在课堂上展示,开阔同学们的思路,激起学习兴趣和主动参与学习的欲望。
适当安排竞猜抢答、快速反应、
角色扮演、小组讨论、记者采访等活动,激励学生大胆开口说英语,提高他们运用语言的能力,变“学会”为“会学”。
建构一种新型的现代教育模式,让学生在轻松愉快的环境下获得更多的信息交流。
四、教学程序设计
根据识记认知规律和教学原则,我把教学程序分为以下几个环节;复习一引入新课—操练一运用一巩固练习。
1.‘激趣抢答,温故知新:告诉学生我们将玩一个游戏——考考你。
快速展示一组图片,如:电话、电视机、电脑、计算器、飞机等,然后提问学生:
A.How many things have you seen?
B.What are they?
C. What was invented before the car?
活动设计意图:以抢答形式完成,目的在于吸引学生的注意力,激起他们的学习兴趣。
在回答问题的过程中,激活学生与本课学习目标相关的原有知识基础,开阔学生的思维,达到温故知新的目的,为引入新知作好铺垫。
2.设问置疑,导入新课。
展示一幅计算机的图片,然后提问学生:
A. Do you like computers?
B.If you want to know more informa-tion about the inventions, what will you do?
C. So computer is very important for usto know more besides books, isn&acute;t it?
学生回答这些问题后,及时导入新课,提问:
Do you know who invented the com-puter?
When was it invented?Now. let&acute;scome to Unit9 SectionA to find out the an-swers.
活动设计意图:“良好的开端是成功的一半”,我根据课文内容和学生的年龄特点创设这一情境,激发学生的求知欲,使学生进入最佳的学习状态,在这种状态下接着讲授新课。
展示电视机图,提问:
1 )What&acute;s this in English? Is it a com-puter?
2)Who was the inventor of TV?
3 )Is this invention useful?
这几个问句引出本课的生词:
invent invention inventor inventive
老师讲解词义和构词法,接着展示其他几幅图,学生轮流用英语快速说出所有物品名称,然后回答下列问题:
What&acute;s the most usefulinvention?
Who invented it?
When was it invented?
What was it used for?
从而巧妙地引出本课的重点句型,然后让学生运用这些句型分小组进行操练。
这一环节,贯彻了直观性和循序渐进的原则。
活动设计意图:通过提问和抢答实现了两个教学目标——单词和句型的掌握和运用。
3.视听联想,加深理解
告诉学生准备好辨图、听声,然后说出物品发明时间及用途,(简笔画)黑板上画简笔画,让学生分组抢答后,请1-2个学生用下面的语言结构说出:
The invention is…It was invented in- -by… And it is used for…
接着播放汽车喇叭声、自行车铃声及电话铃声等,让学生听声音说出
物品的名称、发明的时间和用途。
以上操练利用了视听联想手段,发挥学生的想象力,培养他们的发散思维和观察、分析问题的能力,通过积极思维达到自主学习的目的。
4.合作小结,拓展延伸
为了让学生学懂会用,学以致用。
我创设以下语言情境:
(1)设置几个问题让学生分组讨论
A. If you are a scientist, what do youwant to invent most? Why?
B. Who do you think is the greatest in-ventor in the world? Why?
C. What do you think is the most inter-esting invention? Why?
D. If you had money, what would youlike to own? Why?
小组成员对讨论的结果进行整理后,请一名代表向全班同学展示小组讨论结果。
(2)发明给我们带来了什么?
学生分小组列出教室里或书包内的十项发明,并填入表格。
在小组内根据发明的用途进行讨论,哪些发明对人类有益,哪些发明给人类带来了烦恼。
What do you think is the most helpfulinvention?
What do you think is the most boringinvention? Why?
活动设计意图:这一环节体现了学以致用的语言教学原则,优化英语课堂教学过程的其中一个重要方面便是丰富和拓宽教学内容,培养学生的创造精神以及发散思维。
给学生提供一种协作学习的环境。
这种形式有利于师生之间、学生之间相互传递和接受信息,有利于激励学生参与,实现课堂教学交际化。
5.探究应用,练中巩固
为了引导学生牢固地掌握所学过的知识,结合本课语法,被动语态过去时的用法,我设计了以下练习:
(1)听力练习
完成课本上1b Listen and match theinventions with the date.
(2)选择填空
1. The cup is used for___tea.
A. drink
B.drinks
C.drinking D.to drink
2.The tall building near here____in 1987.
