Unit 2 communication Lesson 4 Animal Talk 教材分析本課是北師大版初中英語八年級上冊教材第二單元，話題為“交流”。本課是本單元第一課，在承接Get Ready部分有關(guān)“Communication”話題的基礎(chǔ)上，本課重點(diǎn)介紹動物的交流手段和方式。本課的教學(xué)設(shè)計(jì)分為兩個(gè)課時(shí)。第一課時(shí)側(cè)重對課文的理解，首先通過頭腦風(fēng)暴激活學(xué)生已有的知識：你所了解的動物都有哪些交流方式。隨后通過閱讀，獲取動物的三種主要交流方式。第二遍和第三遍閱讀獲取細(xì)節(jié)信息：課文中所提到的動物分別采用哪種交流方式；動物交流的目的是什么。最后結(jié)合課文信息和Get Ready部分所討論的話題內(nèi)容進(jìn)行語言輸出活動：對比人類和動物的交流有什么不同。在本節(jié)課中還會滲透現(xiàn)在完成時(shí)的相關(guān)知識，主要從語用功能層面，使學(xué)生對現(xiàn)在完成時(shí)有初步的認(rèn)識和了解。第二課時(shí)在復(fù)習(xí)課文內(nèi)容的基礎(chǔ)上，引入本課的重點(diǎn)語法內(nèi)容現(xiàn)在完成時(shí)，通過觀察和分析例句，發(fā)現(xiàn)并總結(jié)現(xiàn)在完成時(shí)的含義和句型結(jié)構(gòu)。通過分層練習(xí)，進(jìn)一步體會現(xiàn)在完成時(shí)的含義，以及與一般現(xiàn)在時(shí)的區(qū)別。第二課時(shí)的教學(xué)還包含對學(xué)生學(xué)習(xí)策略的指導(dǎo)既不知道詞義的情況下可以查字典，而在諸多義項(xiàng)中選取恰當(dāng)?shù)脑~義還要回歸上下文。 教學(xué)目標(biāo)【知識與能力目標(biāo)】1.
