Unit4Iwanttobeanactor教学目标：1.学会不同工作的英文表达方式。2.了解同学父母的工作。3.学会简单的介绍自己将来的理想。教学内容：重点词汇：teacher,nurse,engineer,manager,airhostess,lawyer,doctor,clerk,reporter,police重点句型：1.Whatdoesyourmotherdo?Sheisateacher.Whatdoesyourfatherdo?Heisanengineer.2.Whatdoyouwanttobe?Iwanttobeateacher.Whatdoesshewanttobe?Shewantstobeasinger.总体思路:本单元采用任务型的教学模式，设计了三个任务活动，首先以比赛的形式，让学生通过工作的描述，来猜测工作的名称；然后由学生自己下座位找与自己父母工作相同的同学，练习所学的句型；其后让学生用所学句型谈论自己的理想。所有任务的设计，由简到难，每一个任务都为下一个任务的完成奠定了一定的语言基础。语法知识一般现在时（1）一般现在时主要由动词原形表示，但第三人称单数后要加-s，另外be有特殊的人格形式，见下表:一般现在时行为动词(以work为例)动词tobeIwork．Youwork．He/She/Itworks.Wework．Iam（I'm）...Youare（You're）...He/She/Itis…Weare（We're）...行为动词动词tobeYouwork．Theywork．Youare（You're）...Theyare（They're）...（2）一般现在时的否定式见下表一般现在时的否定式行为动词(以work为例)动词tobeIdonot（don't）work.Iamnot（I'mnot）…Youdonot（don't）work.Youarenot（aren't）…HeShedoesnot（doesn't）work.ItHeSheisnot（isn't）….ItWeYoudonot（don't）work.TheyHeSheisnot（isn't）….It（3）一般现在时的疑问式及简略回答，见下表。一般现在时的疑问式行为动词(以work为例)动词tobeDoIwork?Yes,youdo.No,youdonot.（don't）Doyouwork?Yes,Ido.No,Idonot.（don't）Doeshe/she/itwork?Yes,he/she/itdoes.No,he/she/itdoesnot.（doesn't）Dowework?Yes,we/youdo.No,we/youdonot.（don't）Doyouwork?Yes,wedo.No,wedonot.（don't）Dotheywork?Yes,theydo.AmI...?Yes,youare.No,youarenot.（you'renot.或youaren't）Areyou...?Yes,Iam.No,Iamnot.（I'mnot）Ishe/she/it...?Yes,he/she/itis.No,he/she/itisnot.（he's/she'sit'snot）Arewe...?Yes,we/youare.No,we/youaren't.（we/youaren't.we're/you'renot）Areyou...?Yes,weare.No,wearenot.（aren't/we'renot）No,theydonot.（don't）Arethey...?Yes,theyarenot.（aren't/they'renot）（4）一般现在时的基本用法如下。①经常性或习惯性的IgetupatsiGeveryday．②客观真理，客观存在，科学事实。Themoonmovesroundtheearth．月亮围着地球转。③表示格言或警句中。Pridegoesbeforeafall.骄者必败。④现在时刻的状态、能力、性格、个性。Idon'twantsomuch.教学板块设计:Task1：Knowthenamesofthedifferentjobs目的：通过这个环节，教师完成本单元的新单词的导入，通过提供给学生对于不同工作的具体描述，让学生猜出工作的名称，这样为整节课任务的完成奠定最基本的词汇基础。在做猜谜游戏时学生能够做到精神集中，并能激发学生的学习兴趣。课前准备：教师需要准备关于teacher,nurse,engineer,manager,airhostess,lawyer,doctor,clerk,reporter,police等工作的具体文字描述。课堂学生活动：1.教师向每个小组发放一份关于工作的描述，竞赛看那个小组最先猜出答案，并将本组的谜语提供给全班，让其他组竞猜，这可以将学生的注意力，吸引到课堂上来，并对同学年的谜语加以思考。此活动以小组为单位，让学生通过谜语来猜测工作的名称，猜对者给小组加分。Theriddlessuppliedbytheteacher:1)Iworkinthehospitaleveryday.Myworkisveryhardbutalsoveryimportant.Thedoctorsandpatientsneedmyhelp.Ihelpthedoctorandlookafterthepatients.Ialwayswearwhiteclothes.Peoplecallus“angelsinwhite”.2)Idriveacareveryday,butthecarisnotmine.Therearemanypeoplesittinginmycareveryday.Aftertheygooutofthecar,theymustpaymemoney.3)Myjobisverydifficultbutinteresting.Ihelppeopleonthecourt.IfIsucceedIwillgetlotsofmoney,butifIfail,Igetnomoney.4)Iamveryproudofmyjob.BecauseIamyou...
