本單元為科技類說明文，為高考閱讀理解重要題材。在高考中占有重要地位。本堂課是閱讀課，為了訓(xùn)練和提高學(xué)生的閱讀技能，在教學(xué)過程中采用任務(wù)型語言教學(xué)法。采取的任務(wù)由淺入深，由易到難，步步推進(jìn)從而實(shí)現(xiàn)學(xué)生閱讀的目的。本節(jié)課以任務(wù)推動(dòng)學(xué)習(xí)，以任務(wù)貫穿學(xué)習(xí)。課堂活動(dòng)由聽、說、讀、寫4種語言展現(xiàn)形式組成一個(gè)個(gè)小任務(wù)，形成任務(wù)串，前后環(huán)環(huán)相扣，達(dá)到理解課文、用自己的語言重新詮釋課文的目的。學(xué)生對(duì)電腦并不陌生，日常中也經(jīng)常接觸電腦，因此此話題為學(xué)生熟悉話題，閱讀上不會(huì)有太大障礙。學(xué)生整體英語水平不是太高，因此會(huì)導(dǎo)致閱讀中出現(xiàn)卡殼現(xiàn)象，閱讀設(shè)計(jì)的難度不要太大，同時(shí)再設(shè)計(jì)中要考慮給學(xué)生幫助。如小組合作可以幫助學(xué)生解決大部分困難。文本中出現(xiàn)的專業(yè)術(shù)語較多，因此需要學(xué)生提前預(yù)習(xí)充分。小組內(nèi)差異較大，需要在教學(xué)中予以指導(dǎo)。1.Puttheminanorderaccordingtothetime.()analyticalmachine()laptop()calculatingmachine()robot()PC()universalmachine2.Fillinthecloze:1642Thecomputer__________________machine．The_________machinewasmadebyCharlesBabbage.1936AlanTuring_____________________howcomputerscouldbemadetowork．1940sComputershad________________aroom.Afamilyofcomputerswasconnectedbyanetwork.1970sFirstas_____andthen________computerswereusedinofficesandhomes.NowComputersconnectpeopleallovertheworldtogether今天聽了當(dāng)老師的一節(jié)課，必修二unit3computers。上課環(huán)節(jié)流暢，內(nèi)容銜接得當(dāng)。導(dǎo)入采用生活中的事物和常見的縮略語，如WWW,PC,IT，telephone，washingmachine等，一下子調(diào)動(dòng)了學(xué)生的積極性和興趣。雖然當(dāng)今電腦很常見，但是這些詞的完整形式卻并非人人都會(huì)。此意調(diào)動(dòng)了學(xué)生的積極性，一下子拉近了課堂的距離。接下來的閱讀采用漸進(jìn)式閱讀教學(xué)策略，通過快速閱讀，獲取文章的基本信息點(diǎn)，讓學(xué)生有一個(gè)大概的了解，為下一步細(xì)節(jié)閱讀中的迅速定位打下了基礎(chǔ)。通過討論的方式讓學(xué)生交換思想，既避免了閱讀課的枯燥，又能鍛煉學(xué)生的交流能力，同時(shí)對(duì)于基礎(chǔ)較弱的學(xué)生來說也是一個(gè)促進(jìn)。接下來的細(xì)節(jié)閱讀，讓學(xué)生更好地了解文本，鍛煉學(xué)生分析文本的能力。此處繼續(xù)采用小組合作討論的形式。最后的閱讀檢測(cè)，結(jié)合學(xué)生實(shí)際，內(nèi)容設(shè)計(jì)適中。讓學(xué)生對(duì)文本內(nèi)容有一個(gè)更全面的認(rèn)識(shí)。討論計(jì)算機(jī)的應(yīng)用環(huán)節(jié)，有助于培養(yǎng)學(xué)生思考。學(xué)以致用，加深了對(duì)計(jì)算機(jī)的認(rèn)識(shí)。未來電腦的應(yīng)用視頻開闊了學(xué)生的想象力?？v觀整堂課，環(huán)節(jié)設(shè)計(jì)河里，內(nèi)容有梯度。但是在討論環(huán)節(jié)，學(xué)生時(shí)間稍顯倉促，展示環(huán)節(jié)，學(xué)生的積極性稍顯不足。本單元的中心話題是“計(jì)算機(jī)”，內(nèi)容涉及計(jì)算機(jī)的發(fā)展歷史、計(jì)算機(jī)的應(yīng)用等，其中還談到包括計(jì)算機(jī)在內(nèi)的幾種信息技術(shù)的載體、智能計(jì)算機(jī)的發(fā)明等等。不過，整個(gè)單元多以計(jì)算機(jī)為第一人稱進(jìn)行自白，這種擬人的手法使得文章談起來妙趣橫生，抽象的專業(yè)知識(shí)介紹起來也淺顯易懂。本主旨語篇WHOAMI?以計(jì)算機(jī)的口吻自述其發(fā)展演變的歷史以及計(jì)算機(jī)在當(dāng)今世界各個(gè)領(lǐng)域的運(yùn)用。表達(dá)了計(jì)算機(jī)的發(fā)展變化之快以及在生活中用途之廣。計(jì)算機(jī)這一話題雖然有趣，但本單元所選語言材料屬于科普類說明文，內(nèi)容較為抽樣，文章中也不乏一些專業(yè)術(shù)語，對(duì)于高一學(xué)生來說有一定的難度。Module2Unit3ComputersAimsandrequirements:1.Reorganizeandsharetheirbackgroundofcomputers.2.Learntopredictthecontentofanarticleaccordingtodetails.3.Knowtheadvantagesanddisadvantagesofcomputersindailylife.Processofthestudy:=1\*ROMANI.Warmingup.Questions:Whatarethey?Lookatthepicturesandguesstheirnames.=2\*ROMANII.Skimming:Activity1:1.Gooverthestorytofindoutwhothespeakeris.___________________________2.Choosethebestanswer.1).Themachineisintroducingitselfmainlyaccordingto________?A.functionB.timeC.size2).Whowasthecomputer’srealfather?A.AlanTurningB.Notmentionedinthetext.C.BillGatesD.CharlesBabbage3).Thecomputeralmostchangedcompletely_______.A.in1642B.in1882C.inthe1960sD.inthe1970s4).Whenwerethecomputersconnectedfirstly?A.Inthe1970sB.Intheearly1960sC.In1936D.In1822=3\*ROMANIII.CarefulreadingActivity2:Topicsentencesforeachparagraph:Para1Para2Para3Activity3:TrueorFalse1.AlanTuringbuiltanAnalyticalMachinetosolveanymathematicalproblems.()2.Peoplebegantorealizethatthecomputergotclevererandquickerwithtimepassing.()3.Thecomputerbegantoservethehumanracesinceitwasbroughtintopeople’shomes.()4.Sincethe1970s,thecomputerwasusedbypeoplearoundtheworldthroughtheInternet.()5.Thelargerthecomputeris,themorememoryithas.()Activity4:Choosethebestanswer.1)What’sthemainideaofthetext?A.Thecomputerwantstofind“whoheis”.B.Thefunctionalchangeofthecomputer.C.Thecomputerbecomespopulararoundtheworld.D.Thehistoryanddevelopmentofthecomputer.2)．WhyisAlanTuringcalledtherealfatherofthecomputer?A．Heinventedthecomputer.B．Hemadethecomputersmaller.C．Hemadethecomputerwidelyused.D．Hewroteabookaboutthecomputer.3).Whichofthefollowingstatementsisnotright?AComputerhasalonghistory.BComputerhaschangedgreatlysinceitwasfirstmade.CComputersarewidelyusednow.DComputerwasbroughtintopeople’shomeinthe1960s.4)．Whatcanwelearnfromthetext?A．Thecomputerwilltaketheplaceofhumanbeings.B．Thecomputerwillbesmarterthanhumanbeings.C．Thecomputerwillbeadisasterforhumanbeings.D．Thecomputerwillbeusedinmanyfieldsinlife.=4\*ROMANIV.Postreading1.Puttheminanorderaccordingtothetime.()analyticalmachine()laptop()calculatingmachine()robot()PC()universalmachine2.Fillinthecloze:1642Thecomputer__________________machine．The_________machinewasmadebyCharlesBabbage.1936AlanTuring_____________________howcomputerscouldbemadetowork．1940sComputershad________________aroom.Afamilyofcomputerswasconnectedbyanetwork.1970sFirstas_____andthen________computerswereusedinofficesandhomes.NowComputersconnectpeopleallovertheworldtogetherDiscussion：1.Whatcanthecomputerbeusedfor?Tips:Wecanuseacomputerto…2.Shouldhighschoolstudentssurftheinternet(上網(wǎng))?3.Wha
