Unit 9 When was it invented？（Section A）一．语法：被动语态1.被动语态的时态: 被动语态的时态通过be的变化来体现，它必须与主语的人称、数一致。

以下是几种常用的被动语态:(1)一般现在时的被动语态: am / is / are + 动词的过去分词。

Eg：This book in two languages.这本书是用两种语言写的.(2)现在进行时的被动语态: am / is /are + being + 动词的过去分词。

Eg: A school is by the workers now.工人们正在建一所学校.(3) 一般将来时的被动语态: will / be going to + be + 动词的过去分词.Eg: The project will next month.这项工程下个月就完工.(4) 现在完成时的被动语态: have / has + been + 动词的过去分词.Eg: My homework .我的作业以完成了.(5) 一般过去时的被动语态: was / were + 动词的过去分词.Eg: The classroom three days ago. 教室是三天前被打扫的.(6) 含有情态动词的被动语态: 情态动词+be +动词的过去分词.The classroom every day.教室应该每天都被打扫.2.被动语态的否定句和疑问句:（1）否定句的构成：必须在第一个助动词后加not。

Eg：His homework finished. 他的作业还没有完成。

（2）疑问句的构成：将第一个助动词置于主语之前。

Eg：When the bridge ？这座桥是何时建的？3、主动语态变被动语态的方法:（1）把主动语态变的宾语作为被动语态的主语（2）主动语态的谓语改成be + 过去分词的形式，作为被动语态的谓语，be随着主语以及时态的变化而变化。

（3）主动语态的主语变为by的宾语，有时可以省略。

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。
