主动语态：主语+ 谓语动词+ 宾语+ 其他成分被动语态：主语+ be +过去分词+ by +宾语+其他成分如：被动语态English is spoken by many people.课文知识要点：1、When was it invented?它是什么时候发明的？invent v. 发明→inventor n. 发明家→invention n. 发明可数名词invent v. “发明”指发明创造出自然界本来不存在的东西，如工具、方法、手段、汽车、电器、合成材料等。

Edison, a great inventor, invented over 1’000 inventions all his life.2、What is it used for？它是用来做什么的？be used for“用来做…”；此短语中的for是介词，表示用途，后接名词或动词-ing形式。
Unit 6 When was it invented? 单元语法精讲与精练单元语法精讲被动语态（二）：一般过去时的被动语态1.一般过去时的被动语态的结构肯定句：主语+ was/were+Vp.p + (by…)eg：The car was invented in 1895.汽车是在1895年发明的。
否定句：主语+ was/were+not+Vp.p +(by…)eg：He wasn t told to go to Beijing.没人叫他去北京。
一般疑问句：Was/Were+主语+Vp.p +(by…)?eg：Was the light bulb invented by Edison?电灯是爱迪生发明的吗？回答为：Yes，主语+ was/ were;No，主语+ was/were+not.特殊疑问句:(1)疑问词不作主语：疑问词+ was/were +主语十Vp.p+ (by…)?eg：How was tea invented?茶是怎样被发明的？(2)疑问词作主语：疑问词+ was/were +Vp.p+ (by…)?eg：When was computer invented?电脑是什么时候发明的？2.被动语态的用法(1)当我们不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者时,常用被动语态。
eg：The yellow cup was broken.黄色的杯子被打破了。
(2)当我们主要关心动作的承受者，但也关心动作的执行者时,通常会在动作的执行者前面加by。
eg:The nice picture was drawn by a ten-year-old boy.这幅好看的画是由一个十岁的男孩画的。
单元语法精练一、单项选择。
（）1.—When the bridge ？—Last year.A.did; buildB.was；buildC.was; builtD.did; built （）2.Flowers along the road last year.A.plantB.plantedC.are plantedD.were planted（）3.Many buildings in Lushan in the earthquake on April 20th.A.have destroyedB.are destroyedC.were destroyedD.are destroying （）4.The girl was heard in the next room every afternoon.A.to singB.singC.singingD.sang（）5.—Do you know Earth Day?—Sure.It in 1970 to tell us to protect our planet.A.sets upB.set upC.is set upD.was set up二、按要求完成句子，每空一词。
一、必背短语【教材内容解析】Section A1.I think the TV was invented before the car. (P. 41)invent用作及物动词，意为“发明、创造”，指创造出以前不存在的东西，invention 表示“发明物”；inventor表示“发明家”。
Edison invented the electric bulb.2.changing the style of the shoes (P. 42)style用作名词，表示“样式、款式”，in style表示“流行、时髦”，out of style表示“过时”。
I like different styles of clothes.Long shirts are black in style.3.With pleasure! (P. 42)with pleasure则表示“很乐意去做某事”，强调事情还没有去做，但是表达愿意效劳的意愿。
It’s a pleasure/It’s my pleasure/My pleasure表示“不客气、很乐意效劳”，常用来回答Thank you或者对效劳过的事情表示没什么，很乐意去做。
---Would you please take care of my dog while I am away.---With pleasure.---Thank you for taking care of my dog while I am away.---My pleasure.4.Is it really such a great invention? (P. 42)“such+a/an+adj.+n.”表示“如此……的……”，相当于“so+adj.+a/an+n.”。
I have never read such an interesting book.=I have never read so interesting a book.5.Think about how often it’s used in our daily lives.(P. 42)daily作形容词，表示“每日的、日常的”，相当于everyday。
对比一般过去时和一般将来时的被动语态一、构成对比1. 一般过去时的被动语态：was / were + 动词的过去分词如：The teaching building was built six years ago.这座教学楼建于六年前。
2. 一般将来时的被动语态：“will be + 动词的过去分词”或“am / is / are going to be + 动词的过去分词”如：This museum will / is going to be finished next month.这座博物馆将于下个月竣工。
二、否定形式和疑问形式对比1. 否定形式：★一般过去时的被动语态：was / were + not + 动词的过去分词如：The window was not broken by him.窗玻璃不是他打碎的。
★一般将来时的被动语态：“will not be + 动词的过去分词”或“am / is / are not going to be + 动词的过去分词”如：The new film will not / isn’t going to be show n in our city next week.那部新电影下周不在我们城市放映。
2. 疑问形式：★一般过去时的被动语态：通常把was / were置于主语前。
如：Were the textbooks written in 2000?这些课本是2000年写的吗？Where were those buses made?那些公共汽车是哪里制造的？★一般将来时的被动语态：将will, (be going to中的) am / is / are置于主语之前。
如：When will the road be opened to traffic?这条路什么时候通车？Are we going to be asked to attend the meeting？我们会被邀请参加会议吗？【趁热打铁】Ⅰ. 请选出能填入空白处的最佳选项。
