III. Grammar
一般过去时态的被动语态的构成
英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者, 而被动语态则表示主语是动作的承受者。如：
We cleaned the classroom yesterday.
我们昨天打扫了教室。
（主动语态，主语we是clean这一动作的执行者）
The classroom was cleaned yesterday.
教室昨天被打扫。
（被动语态，主语the classroom是clean这一动作的承受者）
一、一般过去时被动语态
一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词（+by+动作的执行者）如:
Trees were planted last spring.
去年春天种了树。
1.肯定句：
主语+ was/were+及物动词的过去分词+其他.
Paper was invented by Chinese people two thousand years ago.
纸是中国人在二千多年前发明的。
2.否定句：
主语+ was/were not +及物动词的过去分词+其他.
Women were not allowed to take part in the games at first.
开始妇女不允许参加奥运会。
3. 一般疑问句：
Was/Were+主语+及物动词的过去分词+其他？
Were these pictures drawn by your sister?
这些图片是由你妹妹画的吗？
二、被动语态的用法：
1.不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。
e.g. English is spoken all over the world. 全世界都在说英语。
2.需要突出或强调动作的承受者。
e.g. This dictionary is used by most students.
这本字典是大多数学生在用的。
三、主动语态变被动语态应注意的问题
1.有些短语动词相当于及物动词，变为被动句时介词或副词不能去掉。
They put off the meeting because of the weather.
The meeting was put off because of the weather.
会议因天气的缘故被推迟了。
2.含有双宾语的主动句变为被动句时，通常把指“人''的间接宾语变为主语, 指“物”的直接宾语保留不变；如果把指物''的直接宾语变为主语，则在间接宾语前加to或for。
My aunt gave me an e-dictionary yesterday.
I was given an e-dictionary yesterday.
An e-dictionary was given to me yesterday.
3.主动句中感官动词see/hear/watch/feel等和使役动词make/let/have等后跟省略to
的动词不定式，变为被动语态时应加上不定式符号tOo
I saw a heavy man enter the house.
A heavy man was seen to enter the house.
4.系动词、不及物动词或某些短语动词(happen, take place, come true, fall asleep...)没有被动语态。
What happened to Mr. Brown?
布朗先生发生了什么事？
IV.Exercises
练一练
将下列句子变为被动语态。
1.He chose six story books the other day.
Six story books by him the other day.
2.Uncle Lee gave Jack a large cake for he painted the wall wonderfully.
Jack a large cake for he painted the wall wonderfully.
3. A mouse ate half of the cake last night.

4.Were these machines invented by Edison?
Edison these machines?
5.The post card was sent to Linda by Paul.
Paul the post card Linda.
6.America was discovered by Columbus.
Columbus discovered?
V.Practice
Work on 4a:
1. Tell Ss to read the sentences in 4a and rewrite the sentences using the passive voice.
2.做题方法点拨示例：
① 点拨：原句为一般过去时态，原句的谓语动词为sold,宾语为ihe fridge；改为被动语态时，应将the fridge作主语，谓语动词用was sold的形式。
They sold the fridge at a low price.—>
The fridge was sold at a low price.
②点拨：分析原句的句子结构可知，stool是谓语动词，my camera是句子的宾语；改为被动语态句时，应将my camera作句子主语，谓语动词用was stolen 的形式。
Somebody stole my camera from my hotel room. —>
My camera was stolen from my hotel room.
学生们自主将其他三个句子变成被动语态。
3.最后，教师与同学们一起校对答案，并对学生们有疑问的地方进行解释，或做出合理的分析点拨。
Where were these photos taken?
We were advised not to go out alone.
The book was translated into different languages by different writers.

1.让学生们阅读方框中的词汇，了解词汇及句子的意思，为进行填词做好准备。
eat, like, invite, tell, lock, ring, break, bring ~~2.认真阅读每个句子，根据上下文确定空格处应填的意思。
3.逐句进行分析推敲，然后分析句子的时态及语态，用适当的形式填空。

5. Check the answers with the Ss.
1.were invited
2.were brought
3.was locked, rang (前一句中，门是被锁的，故应用被动语态；后一句中，我们去按门铃，是主动语态。)
4.were told, broke (前一句中，学生们是被告诉不要做这些事情，故应用被动语态；后一句中，Ruby违反规则，则是主动语态。)
5.were ealen,liked (前一句中，饼干是被孩子们吃掉了，故应用被动语态；后一句中，孩子们喜欢这些饼干，则是主动语态。)

Unit 6 When was it invented?
本单元围绕“发明”这一话题，学习了解一些重要发明的历史，教学一般过去时的被动语态。Section A介绍了我们日常生活中的一些常见物品的发明历史，如电视、电话、拉链、茶叶等。内容上包括谈论它们的发明时间、被什么人发明、它们的作用和发展等；从语言结构上，学习被动语态的过去时，单元主题图由四副小图组成，呈现的是现代生活中的常见用品：电视、电话、电脑和小汽车。从运用I think it was invented before/after…讨论图片中物品发明的先后顺序开始，到听说训练本单元的重点语言结构：When was it invented？It was invented in…，Who was it invented by？It was invented by…，What was/is it used for？It was/is used for…不断深入学习，再进入阅读训练，训练学生的阅读技巧，学习拓展词汇和语言结构。Section A的重点是培养学生运用被动语态的意识，掌握更多的动词过去分词形式。Section B 依然围绕发明创造这个话题，要求学生继续学习巩固相关的内容和语言知识。在语言技能方面，对听说读写的专项训练和综合训练在本部分里都有体现。在语言策略上，提出让学生学习使用思维导图，以加深对文章的理解和对知识的记忆。在听力训练过程中，需要学生运用反义词、信息综合判断等，训练捕捉信息、处理信息的能力。在阅读训练中，需要学生学习和掌握如何利用思维导图帮助理清、记忆阅读语篇中的相关信息，把获取的信息转换成图形来帮助记忆。积极运用阅读策略有助于学生更好地掌握文章要点和细节等信息，降低语篇的学习难度，也有助于培养学生主动学习的习惯。
