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。

九年级英语Unit9 When was it invented 教案学习目标：1．学会使用含有被动语态的不同句型结构“When/ Where was it invented? ” 和“ What are they used for?--- They are used for doing sth.. ”来谈论各种发明物的历史。
2．学习理解被动语态的含义。
能够就不同的发明物与他人交流看法，发表自己的见解，并陈述理由。
3．了解到更多在世界上有重大意义的发明，并向那些伟大的发明家学习。
一、词汇1．基础词汇invent adjustableheelbatteryoperateslipperscoopelectricbulbmicrowaveovenisland sweetsalty crispy sourpotato chip mistake thin chef sprinkle beverage thousand accordingancient legend emperor boil fire leaf nearby remainnoticeproduce pleasantsmelltastemetalpiebakery throwspecialabacuscenturytelescopecameraterm2．重点短语experience airplane Indiadevelop二、日常用语1. --- When was the car invented---It was invented in 1985.2. ---When were electric slippers invented ？---They were invented last year.3. ---Who were they invented by ？---They were invented by Julie Thompson.4. ---What are they used for ？---They ' re used for seeing in the dark.三、知识讲解Section A:1. 被动语态谓语动词的语态表示句子的主语和谓语动作之间的关系：1）当句子的主语是谓语动作的执行者时，主、谓之间的关系称为主动语态；2）当句子的主语是谓语动作的承受者时，主、谓之间的关系称为被动语态。
例如：I teach English. （主动语态）我教英语。
Our English is taught by him. （被动语态）我们的英语是由他教的。
He speaks English. （主动语态）他说英文。
English is spoken in many countries all over the world. （被动语态）世界许多国家都讲英语。
在被动语态的句子中，谓语部分的结构是be + p.p. （过去分词）。
被动语态的句子有时态的变化，这个变化反映在be 动词上。
也就是说，把一个句子做成被动语态的句子，只需要写出be 动词的所需时态，再加上所给动词的过去分词就行了。
当然，这只是指谓语部分而言。
我们知道，be 动词作为一个独立的谓语动词有自己现在分词（being ）和过去分词（been ）。
那么，下面我们来看看be 在各种时态中的变化形式：般现在时am / is / are般过去时was / were般将来时shall / will + be过去完成时had + been 现在进行时am / is / are + being过去进行时was / were + being 现在完成时have / has + been 过去将来时would / should + be说明：1）以上的八个时态可用于被动式，其它没有列举的时态都不宜用于被动语态的句子中。
2）另外，表中被斜线隔开的词表示根据具体情况作选择。
弄清楚了be 在各种时态中的变化形式以后，我们就能很轻松地写出被动语态的各种时态了。
我们可看看下面的实例：English is spoken in many countries all over the world . （一般现在时）世界上许多国家都讲英文。
Some TV sets for sale in the department store were stolen last night. 那家商场用来出售的部分电视机昨晚被盗。
（一般过去时）He won't be allowed, by his father, to marry Laura. （一般将来时）他父亲不会让他娶劳拉为妻的。
They would be sent to the army when they finished the training.他们结束训练时将被派往部队。
（过去将来时）The project is being carried out. （现在进行时）这个计划正在执行中。
The case was being investigated then. （过去进行时）那时这案子正在调查中。
This novel has been translated into several languages. （现在完成时）这本小说已被译成了几种语言。
They said that production costs had been reduced. （过去完成时）他们说生产成本已经下降了。
2. be used for 被用来做,What is the book used for? 书是用来做什么的？The book is used for readi ng. 书是用来读的The pla ne is used for traveli ng. 飞机是用来旅行的3. accordi ng to 根据，按照4. i n this way 这样5. give sb. some time to do sth 给某人一些时间做某事.The teacher gives the stude nt two hours to do homework.老师给同学们两个小时做作业。
6. help sb. do sth. 帮助某人做某事I ' ll help you leave the island. 我将帮助你离开岛屿。
