Unit 6 When was it invented? Grammar-4c教学设计 一、教材分析 本课选自人教版《新目标英语》九年级第六单元。本单元以发明为主题，引导学生在第五单元介绍产品、艺术品的基础上，进一步利用被动语态来介绍发明物的用途以及背后的故事和历史。本节课的语法梳理符合单元话题，以对发明物的介绍进行感知。在学习后，学生不仅能对被动语态运用的情境有所理解，并能和主动语态有所区分。更重要的是，学生能通过情境理解被动语态在一般现在时和过去时的运用。 二、学情分析 在上一单元的学习中，该班同学已经初步感知和操练了运用被动语态介绍产品和句子，对于一般现在时中的被动语态比较熟悉。但还有一部分学生对于被动语态的语法结构不了解，不懂得在适当的情景当中运用。同时，对于被动语态的过去时形式，很多学生还不懂得如何变化。 教学目标 学生能够掌握主动语态与被动语态的区别，被动语态句子的结构以及使用范围； 学生能够在语境中判断该运用主动语态还是被动语态，并正确的开展表达； 学生能借助思维导图复述关于电话发明过程的短文； 学生能够正确、恰当运用被动语态来介绍发明物的用途以及背后的故事和历史。 教学方法 Task-based Teaching Method；Situational Approach；Audio-visual approach 教学过程 Step 1: Review: An Accidental Invention Students complete the passage with passive voice.

T: Who invented tea? S: Shen Nong invented tea about 5,000 years ago. A book named Chajing was written by Lu Yu. T: Who wrote a book named Chajing?

She translates from Chinese into English or from English into Chinese. She is an excellent translator and she is good at translation.” Students read the different verb forms together. They sold the fridge at a low price. ___________________________________________ Somebody stole my camera from my hote
