Unit 4 Amazing Science Topic 1 Section C（教學(xué)設(shè)計(jì)）
Ⅰ. Material analysis
本課主活動(dòng)是1a。1a 通過(guò)介紹發(fā)明是什么來(lái)繼續(xù)學(xué)習(xí)一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)。學(xué)生通過(guò)完成1a的任務(wù)型閱讀，知道發(fā)明創(chuàng)造并非遙不可及。1b讓學(xué)生學(xué)習(xí)歸納中心句。1c把發(fā)明創(chuàng)造的步驟進(jìn)行整合，讓學(xué)生更加清楚怎樣去發(fā)明創(chuàng)造。2是個(gè)開(kāi)放性的討論，讓學(xué)生在討論的過(guò)程中知道發(fā)明無(wú)論大小都對(duì)我們的生活產(chǎn)生了巨大的影響。3倡導(dǎo)學(xué)生自己去發(fā)明創(chuàng)造，并通過(guò)介紹自己的發(fā)明來(lái)鞏固英語(yǔ)知識(shí)。學(xué)生學(xué)習(xí)了本課之后，對(duì)發(fā)明創(chuàng)造不再感到神秘莫測(cè)，從而萌發(fā)自己動(dòng)手的愿望，有利于激發(fā)學(xué)生的創(chuàng)造精神。3這個(gè)寫作任務(wù)，需要學(xué)生獨(dú)立思考，并運(yùn)用所介紹的寫作小竅門。學(xué)生在短時(shí)間內(nèi)難以很好地完成，故留作家庭作業(yè)。
