1、人教版九年級英語unit 10教學(xué)設(shè)計【教材版本】人民教育出版社 九年級英語【學(xué)習(xí)內(nèi)容】grammar focus, 3a, 3b and 4 of unit 9 when was it invented ?【學(xué)情分析】本節(jié)課是第九單元的第二課時, 學(xué)習(xí)任務(wù)是完成課文grammar focus, 3a, 3b and 4 部分的學(xué)習(xí)。本單元要求學(xué)會談?wù)撝匾l(fā)明的歷史及用途，然后針對各項發(fā)明的用處及特點，發(fā)表自己的看法，并說明理由。話題一直是圍繞著歷史上和日常生活中的重要發(fā)明，通過使用“passive voice”形式的句型，循序漸進地展開討論。課本設(shè)計的活動情景能夠自然地引發(fā)學(xué)生的好奇心，大家

2、積極地投入到話題討論中，寓教于樂，容易引起學(xué)生的興趣；同時，它也有利于開闊學(xué)生的思路，培養(yǎng)創(chuàng)造精神，展開豐富的想象力，人人都能成為“小發(fā)明家”。學(xué)生在第一課時學(xué)習(xí)了本單元的section a 中的1a至2c部分，基本能聽懂、會說本單元要求掌握的部分重要詞匯；在圖片，相關(guān)信息等提示的幫助下，能較好地運用重要句型和掌握主動語態(tài)和被動語態(tài)及相互轉(zhuǎn)換。但是本班的學(xué)生兩極分化比較嚴重，有一部分學(xué)生基礎(chǔ)知識不牢固，前面提到的學(xué)過的單詞和句型就忘得差不多了，特別是對于課文中的語法主動語態(tài)和被動語態(tài)，被動語態(tài)的一般現(xiàn)在時和一般過去時混為一談。所以教師在課堂教學(xué)中應(yīng)面向整體，及時復(fù)習(xí)相關(guān)的知識，包括重要詞匯和句

3、型，前后知識的銜接。同時在設(shè)計上要注意活動的多樣性，激發(fā)他們的興趣，讓每一位學(xué)生能得到不同程度的收獲。 【單元整體目標】 重點詞匯：salty, sweet, sour, crispy, pleasant, potato chips, slipper, leaf, fire, scoop, light bulb, microwave oven, abacus, camera, beverage, be invented by, be used for, by mistake, by accident 重點句型：when was the telephone invented? i think i
