一般现在时的被动语态微课设计方案

1、微课设计方案（脚本）微课名称一般现在时的被动语态制作教师倪芳学校仪征市青山中心学校微课类型及对象讲授型初二学生制作模式录屏软件+PPT微课长度8 分钟制作时间2014 年 12 月 18 日总体思路利用 Camtasia 和 PPT,从学生熟悉的例句入手，帮助学生了解被动语态的基本结构及用法，指导学生在日常交际及学习中正确地使用被动语态来表达。在教学中，针对考点分析，增强学生的应试能力。微课脚本PPT1Introductiontothisperiod.PPT2T:Thisclassletstalksomethingaboutthepassivevoiceinthesimplepresentte

4、介绍被动语态的概念，突出主语与动词的关系。PPT4T:Whenweexpressourideas,wecanuseboththeactivevoiceandthepassivevoice.Lookatthispicture,ifwewanttointroducethenameofthegardentosomevisitors,wecansayWecallthegardentheSlenderWestLake”,atthesametime,wecanalsosayThegardeniscalledTheSlenderWestLake.”T:BothofthetwosentencesareOK.I

8、T:inasentenceofpassivevoice,theobjectoftheverbwillbethesubject,andtheverbpartconsistsofbeandthepastparticipleformoftheverb.我们将主动语态变成被动语态时，首先把原句中的动词宾语变成被动语态句子的主语，谓语动词部分则改为助动词 be+动词的过去分词，原来的主语则在介词 by 后面做宾语。T:Now,letssumupthestructureofasentenceofpassive.ThatisSubjectplusbeandpastparticipleformofthever

9、b.助动词 be 来体现时态的变化，在一般现在时中，be 可以是 am,is,are 三种形式。【设计意图】通过例句分析被动语态句子的形成过程，让学生归纳出被动语态的句子结构。PPT8T:pleasetransformthefollowingintothepassive.No.1Theroadsarecleanedeveryday.No.2Iamoftenhitonmyheadbyhim.No.3MorevisitorsarewelcomedtoYangzhou.No.4Lotsofhomeworkisdonebystudents.【设计意图】以练习的形式来巩固刚刚所学内容。PPT9&

11、gcases:1,感官动词，使役动词等在主动语态中后接零动词不定式形式，变成被动语态时要加上to”.例如 see/hear/noticesbdosth 句式在被动语态中要改成 sb.beseen/heard/noticedtodosth.Let/make/havesb.dosth.句式在被动语态中要改成 sb.belet/made/hadtodosthPPT12Nowpleasetransformthefollowingintothepassive.Theworkersweremadetoworkallday.Sheisoftenheardtosingintheroom.Someboyswer

12、eseenplayingfootball.【设计意图】练习巩固上一张幻灯片所讲内容。PPT13&142,双宾语结构变为被动语态时应注意以下两种情况，我们常把间接宾语（即 sb）变为主语，若把直接宾语（即 sth.）变为被动句的主语时，常在保留宾语前加 to 或 for。3,主动语态中“动词+介词”或“动词+副词”的短语动词变为被动语态时，介词或副词不可拆开或漏洞。Herearetwoexamplesforyou,readthemcarefully.PPT15请注意以下几种不用被动语态的情况：不及物动词（vi）没有被动语态。如：happen,cost,dieStart/begin,fin

13、ish,rise,appear,dropetc.联系动词（linkingV）没有被动语态。（seem,look,become,get,grow,turn,remain,stay）些固定结构无被动。如：takeplace,setout,cometrue,breakout,comedown,belongto有些动词既是及物又是不及物，当他们与 well,badly,Easily 等副词连用时表示主语内在品质或性能，无被动。如：Theclothwasheseasily.Thepenwritessmoothly.Thenewproductsellswell.PPT16T:nowpleasefinish
