Unit9Whenwasitinvented?一.教学内容：Unit9Whenwasitinvented?二.学习目标：1.动脑筋，找规律，弄清主动语态与被动语态之间的差异，通过练习和运用加以巩固。2.学会使用含有被动语态的不同句型结构来谈论各种发明物的历史。3.通过熟悉我们周围经常使用的发明物的历史来开阔眼界，丰富自己的阅历，使自己养成勤于思考善于总结的好习惯。三.教学重点难点：一般过去时的被动语态及本模块中的一些重点短语四.教学过程:一、stepone:dictation1、beangrywith2、payattentionto3、tomysurprise4、remindof5、comeupwith6、not---intheslight7、getalongwith8、bewillingwith9、assoonaspossible10takeiteasy二、steptwo:preparingAsk:Whoinventedtea?Howwasitinvented?Newwords:byaccident;beverage;accordingto;ancient;legend;bush;fallinto;remain;notice;produce;pleasantReadandanswer:1、Whatisthearticleabout?2、Whenwasitinvented?3、Whowasitinventedby?4、Howwasitinvented?三、stepthree:languangepoints1、not---until2、sometime;sometimes;sometime;sometimes四、stepfour:theinventionofflyingdiskTheflyingdiskwasinventedbycollegestudentsin1950s,abakeryinBridgeport,Connecticutwasveryfamous.Thestudentsalwaysbuysomethingeatingfromthere.Theyatethebakery'spies,thenthrewthepieplates.Itwasanewkindoftoyinthatcentury,theycalledthetoy"FlyingDisk".Today,therearemanyclubs,magazinesandfestivalsaboutthenewtoy"FlyingDisk",andpeoplealsoenjoyplayingflyingdisk.五、课堂检测改为被动语态1、Wecallmathsthelanguageofscience．2、PeoplegrowriceinSouthChina.3、Weplantedmanytreeslastyear.4、HeteachesEnglishinourschool.5、Thestudentscleanedtheroomjustnow6、Mikebrokethewindowyesterday.7、Youmustcleanyourroomeveryday.8、Wemustkeepthenoiseunder50dbshere.教学反思：一节课下来，学生的整体配合和反应还是不错的，但其中有个细节我处理的很不妥。当学生对这句（Hewasboilingdrinkingwateroveranopenfire）的翻译出现问题的时候,我没能进行有效的引导，而是直接告诉答案，教学效果差。
