2019-2020年高中英語 Unit 3 Life in the future教案 新人教版必修5 【美文閱讀】　 Robotic age draws closer 隨著科技的發(fā)展，機(jī)器人時(shí)代的到來已經(jīng)指日可待。 These days，robots are more mon than you might think.Consider the Roomba，a robotic vacuum(吸塵器)which cleans floors on its own. “We wanted to make something simple that people could use every day，”says Greiner，cofounder of IRobot，the pany that makes the smart vacuum.“And thats what inspired us to build the Roomba.” Some robots like the Roomba are already very mon in many US households. IRobot makes everything from the Roomba to robots that someday might bee a part of us. “You can have robotics equipped into your body，to get back that arm or leg that youve lost，either in some accident or disease，”says Greiner. Although robots have been developed mainly for military(軍用的)applications，civilian uses for the technology are growing，according to Michael Toscano，president of the Association for Unmanned(自控的)Vehicles International. “Unmanned systems allow human beings to do their task with an extension of their hands，their eyes and their ears.” “We can put them in the ocean and theyll swim for eight or nine months，collecting data and monitoring ocean pollution，”says Hudson of IRobot. Recently the US Governments Defense Advanced Research Projects Agency (DARPA)displayed a “robotic man”． Instead of depending on remotecontrol，DARPAs “robotic man” can actually look at some blocks，find one with a special pattern，and move it to a new location.Mandelbaum，DARPAs project manager，says more challenging tasks lie ahead. Some day，a DARPA robot might find a hidden bomb or help a disabled person select a shirt and button it. To advance the technology，DARPA plans to let members of the pubic write software for the “robotic man”，then sign onto the Internet and watch a model of “robotic man” perform the task. Its one of the ways that robots will help humankind to extend its reach. 【誘思導(dǎo)學(xué)】　 1．The example of the Roomba shows that . 2．Do you think that robots will play an important role in the future？Why? 【答案】　1.civilian uses for the robotic technology are growing　2.Yes.Because there may be more and more robots ing into our life with the development of science and technology.(answers are different) Period ⅠPreviewing (教師用書獨(dú)具) ●教學(xué)目標(biāo) 初步掌握本課文中的詞匯，淺層次理解課文，了解相關(guān)的背景知識(shí)。 本課時(shí)主要是通過學(xué)生對(duì)學(xué)案所給出的內(nèi)容的學(xué)習(xí)，了解本課文中所出現(xiàn)的詞匯，初步了解課文以及相關(guān)的背景知識(shí)，讓下一堂課對(duì)課文的全面理解起到一個(gè)鋪墊作用。 ●教學(xué)地位 本單元的中心話題是“談未來”。內(nèi)容主要涉及人類對(duì)今后生活環(huán)境的想象、猜測和思考。語言技能和語言知識(shí)主要圍繞“未來生活”這一中心話題進(jìn)行設(shè)計(jì)的。 (教師用書獨(dú)具) ●新課導(dǎo)入建議 可以通過填寫教材第17頁的表格引導(dǎo)學(xué)生去認(rèn)識(shí)現(xiàn)在和展望未來。想象一下100年后人們?cè)诮煌?、工作、語言、環(huán)境，住房和教育等方面的改變和面對(duì)的問題。讓學(xué)生通過思考，讓學(xué)生在思考的基礎(chǔ)上得出自己的結(jié)論，即哪些變化好，哪些變化不好，并說出理由。 ●教學(xué)流程設(shè)計(jì) 導(dǎo)入新課?！鷮W(xué)生閱讀“美文閱讀”與“誘思導(dǎo)學(xué)”(見學(xué)案第37頁)。→學(xué)生就“話題美文導(dǎo)讀”進(jìn)行討論，統(tǒng)一答案?！　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　? 學(xué)生再次閱讀課文(見課本第17－18頁)并完成“語篇理解”(見學(xué)案第38頁)?！麕熒餐懻摬⒔y(tǒng)一答案。←讓學(xué)生快速閱讀課文(見課本第17－18頁)，并完成“篇章結(jié)構(gòu)”(見學(xué)案第38頁)。 　　　　　↓ 學(xué)生共同討論，并讓學(xué)生發(fā)表各自見解，最后統(tǒng)一答案?！鷮W(xué)生再次仔細(xì)閱讀課文(見課本第17－18頁)進(jìn)行深度理解，并完成“課文縮寫”(見學(xué)案第38頁)?！蠋熤笇?dǎo)學(xué)生討論，共同找出答案。 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　↓ 讓學(xué)生根據(jù)所給出的表格進(jìn)行自我評(píng)估(見學(xué)案第39頁)?！麑W(xué)生討論，并讓學(xué)生代表發(fā)表他們討論得出的答案。老師予以更正?！寣W(xué)生完成“知識(shí)初探”部分(見學(xué)案第38頁)。 　　　　　↓ 老師布置作業(yè)，讓學(xué)生看課本第17－18頁并完成課本第19頁1、2、3、4題，預(yù)習(xí)學(xué)案Period Ⅱ(見學(xué)案第39－45頁), 寫一篇關(guān)于想象1000年后地球會(huì)是什么樣子的文章。 (見學(xué)生用書第38頁) Ⅰ.篇章結(jié)構(gòu) 閱讀P17～18的Reading部分，完成下列表格(每空不超過3個(gè)單詞) Before getting into the time capsuleIn the capsuleWe climbed in 4. a small opening.The seats were 5. .
