Period4(SectionB2a-2e)設計說明本節(jié)課通過了解機器人的發(fā)展史以及觀看有關機器人的視頻，激發(fā)學生的學習興趣和求知欲望。通過看圖說話、師生問答來學習新單詞并引入新課內(nèi)容。在閱讀訓練中，通過閱讀前、閱讀中和閱讀后分步驟的系統(tǒng)訓練，讓學生掌握閱讀技巧，提高學生的閱讀理解能力。在閱讀過程中，通過小組合作、共同探究、共同分析問題、解決問題，提高學生的自學能力。教學目標1.知識目標：(1)掌握單詞和短語：human，servant，dangerous，already，factory，Japan，believe，disagree，even，agree，shape，fall，inside，possible，impossible，side，overandoveragain，hundredsof，falldown，lookfor。(2)掌握句型：“Therearealreadyrobotsworkinginfactories.”“However，somescientistsbelievethatalthoughwecanmakerobotsmovelikepeople，itwillbedifficulttomakethemreallythinklikeahuman.”。2.能力目標：(1)能夠運用所給信息，如標題、圖片等預測文章大意，進而掌握課文。(2)能夠運用本課的核心句型，運用will句式想象和預測未來社會發(fā)展。(3)運用一般將來時談論未來。3.情感目標：培養(yǎng)學生敢于設想，勇于實踐的精神。重點難點1.重點：(1)掌握重點單詞、短語、句型。(2)用一般將來時談論未來。2.難點：一般現(xiàn)在時，一般過去時和一般將來時三種時態(tài)的辨析和綜合運用。教學準備1.準備與詞匯及課文相關的圖片。2.準備錄音機、磁帶及多媒體課件。教學過程Step1Warmingup&LeadinginT：Goodmorning，boysandgirls!First，let’senjoyamovie.Whatisthemovieabout?Ss：Robots.T：Yes.Thesearerobots.Nowlet’sreadapassageaboutrobots.機器人發(fā)展史機器人大致經(jīng)歷了三代發(fā)展：第一代機器人是簡單個體機器人，只具有記憶、存儲能力，按相應程序重復作業(yè)，但對周圍環(huán)境基本沒有感知與反饋控制能力。第二代機器人為群體勞動機器人。它能夠獲得作業(yè)環(huán)境和作業(yè)對象的有關信息，進行一定的實時處理作業(yè)，在工業(yè)生產(chǎn)中得到廣泛應用。第三代機器人是目前正在研究的“智能機器人”。它不僅具有更加完善的環(huán)境感知能力，而且具有邏輯思維、判斷和決策能力，可根據(jù)作業(yè)要求與環(huán)境信息自主進行工作。T：Todaywe’lllearnanarticleaboutrobots.Step2Presentation(Showthestudentsapictureaboutaboy.)T：Hereisapicture.Whatistheboydoing?S1：Heisplayingsoccer.T：Whereisheplaying?S1：Onthestreet.T：Isitdangeroustoplaysocceronthestreet?(板書dangerous)Ss：Yes，itis.T：Nowlet’slearnallthenewwordsinthislesson.Pleaselookatthescreen.Whocanreadthem?S2：Ican.(Newwords：human，servant，dangerous，already，factory，Japan，believe，disagree，even，agree，shape，fall，inside，possible，impossible，side)Readandwriteallthenewwords.Thenfillintheblanks.safe(反義詞)dangerous
