課標分析高中英語新課程改革要求，在課堂教學中，要以學生為主體進行教學，教師在教學中起主導作用。因此，我采用任務型教學方式，每一部分都設有一定的任務，引導學生獨立或合作完成。教學過程由復習開始，引出本課的主線，進行閱讀、討論、理解和歸納、總結。每個環節都圍繞“JohnSnowDefeats“KingCholera””這個中心展開。學生快速閱讀文章，了解主人翁約翰.斯諾的成功事跡，總結出他的努力、堅持不懈等品質。學生通過反思自己的學習生活，促使情感目標上升，懂得向偉人學習。通過本次課教學目標的達成，幫助學生樹立信心，特別是不夠自信的學生，激勵他們只要自己去努力就一定會有收獲。整個教學活動以教材為載體，以學生為主體，學生的參與貫穿始終，既有個人活動，又有小組活動和班級活動，充分調動各個感官進行聽、說、讀、寫，提高學生的閱讀速度和準確度，訓練查找、分析、處理信息的能力。教材分析本課時圍繞本單元的中心話題“偉大的科學家”展開，介紹了另一位學生們不太熟悉的醫生—約翰.斯諾。在約翰.斯諾醫生所生活的年代，霍亂病是一個可怕的疾病，因為當時人們不知道霍亂發病的原因，更不知道如何預防和治療霍亂。約翰.斯諾經過實驗最終戰勝了霍亂王。他的事跡能激發學生刻苦鉆研的精神。本節課是一個對學生的閱讀技巧和語言運用能力的綜合訓練材料。它將快速閱讀和口語表達融為一體，是一個綜合課。所以上好本課是對學生的聽、說、讀和寫能力的最好鍛煉。學情分析經過高一的學習，學生的聽說讀寫各方面的能力都有了一定的基礎，但尚有不少學生的說和寫的能力相對欠缺。在本課時之前，學生已經通過閱讀文章對偉大女性有了一定的了解和興趣，并對本單元的詞匯進行了比較系統的學習和訓練。如何利用原有資源練習英語口語就成為了本節課的學習重點。另外，進入高中后由于課程難度加大，許多學生對自己所付出的辛苦是否可以有所回報產生了懷疑，從而產生一種自卑的心理，甚至會覺得自己再努力，成績也得不到提高。所以，自信心不足是他們學習上最大的攔路虎。期待通過本課的學習后，學生能重拾信心，讓他們相信只要有付出就會有回報，并告訴學生要自信、自立、自強，像林巧稚一樣在艱苦的環境中努力工作并不忘幫助別人，為自己的人生畫上一道道彩虹，讓自己的親人、朋友為自己的成就而感到自豪。教學設計課題名稱：JohnSnowDefeats“KingCholera”教學目標1.語言知識（Knowledgeobjectives）a)TeachingAims教學目標:1.Torecallthewordsusedtodescribethequalitiesofagreatscientist.2.TolearntofindouttheachievementsofJohnSnowbyusingsomereadingskills.3.Toimprovestudents’spokenEnglish.b)TeachingImportantPoints教學重點:1.GetthestudentstofindoutJohnSnow’sachievements.2.Enablethestudentstofindtheanswerstoquestionscorrectly.c)TeachingDifficultPoints教學難點:1.Howtoguidethestudentstogetthestructureofthispassageandconcludethemethodofdoingaresearchsmoothlyandeffectively.d)TeachingMethods教學方法:1.Gothroughthetexttogettheanswers.2.Guidethestudentstogetthestructureofthispassageandconcludethemethodofdoingaresearch.3.Discussingroups.e)TeachingAids教具準備：Acomputer使用多媒體教學，制作PowerPoint課件呈現教學內容，增加教學的直觀性，使教學節奏緊湊，調動學生的學習積極性，提高學生學習英語的效果。2.Knowledgeandskill語言技能:1.EnablethestudentstofindouttheproperwordsdescribingJohnSnow.3.Askthestudentstodiscussthetaskandlearntoexpressthemselves.3.ProcessandStrategies學習策略:1.Explanationtoacquaintthestudentswiththeskillsofreading.2.Groupworkorindividualworktoinvolvethestudentsinaheateddiscussion.3.Guidancetoacquaintthestudentstoconclude.4.FeelingsandValue情感態度:Byreadingthispassage,thestudentsmaygetmoreinformationabouttheimportantscientist—JohnSnow,whowasthefirstdoctortospecializeincholera.Hisstorymayinspirealotofstudents.教學過程StepI:ReviewandLead-in1.Whatimpresses（使有深刻印象）youmostin2003?2.WhichpersonimpressesyoumostduringtheSARS?StepⅡ:Reading1.Pre-readingT:Doyouknowthepicture?Whoishe?T:Whatachievementsdidheget?(FromtheWarmingUp,studentsknowthatitisJohnSnowandhewasadoctor,anddevotedallhislifetohiscareer.)2.Fast—readingReadthepassagequicklyandfindthenumbersinthetext,thenfillinthetable.In1854
