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。

詹大悲中学初三英语导学案：Unit9 When was it invented？（Section A）A.课前预习1.预习sectionA的主要知识点（请学生务必根据自己的学习情况自由补充！！）被动语态小结：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。

九年级英语Unit 9 hen as it invented教案九年级英语Unit9henasitinvented 教案语言点归纳被动语态被动语态表示句子的主语是谓语动词所表示的动作承受者。

被动语态基本结构：be+及物动词的过去分词被动语态中的be是助动词，有人称、数和时态的变化。

一般现在时被动语态为：a/is/are+ 过去分词一般过去时被动语态为：as/ere+过去分词与情态动词连用的被动语态：情态动词+be+过去分词被动语态中动作的发出者或执行者做介词b的宾语，放在句末，b表示“由，被”的意思如何理解被动语态？为取胜更清晰、更深刻地理解被动语态的含义，可以将主动语态和被动语态的句子结构进行比较。

主动语态：主语+谓语动词+ 宾语+其他成分被动语态谨+be+过去分词+其他成分如：an peplespeaEnglish被动语Englishisspenban peple2本单元要掌握的句型觅P69中的GraarFus 3inventv 发明inventrn 发明家inventin n 发明可数询4beusedfrding 用来做 (I)Pensareusedfrriting 笔是用来写的。
