Unit 14 The Language of Honey Bees教學(xué)設(shè)計

蘭溪五中 外語組 龔小芳

一. 教材分析

本篇課文The language of honey bees 是新編英語教材第三冊的第14單元，是一篇科技性說明文。講述了一位科學(xué)家對蜜蜂交流食物信息途徑的研究。涉及到蜜蜂如何通過舞蹈傳遞食物的遠(yuǎn)近和距離等內(nèi)容。就本單元Zoology而言，reading部分是本單元的中心，一方面有warming- up 和 speaking 當(dāng)中學(xué)到的有關(guān)動物的知識為其作鋪墊，另一方面此課的學(xué)習(xí)又為下面的Primates 打下基礎(chǔ)，使學(xué)生能在reading 中學(xué)到的關(guān)于動物的信息和探索的科學(xué)方法，以及閱讀中獲得的閱讀技巧得到更好的應(yīng)用和發(fā)揮。就本冊教材而言前四個單元都是有關(guān)對自身極限和對自然界的探索，在第十單元又涉及到了成功的關(guān)鍵，這就為本課的學(xué)習(xí)奠定了情感基礎(chǔ)。另一方面，這是第十三單元的課文，已接近本冊書的結(jié)尾，所以在語言能力的各個方面學(xué)生也都有了一定的積累。因此，從內(nèi)容上看，本節(jié)課是對前面所學(xué)單元主題的再現(xiàn)與升華。本課的學(xué)習(xí)可以進(jìn)一步培養(yǎng)學(xué)生的探索能力，推理能力和空間的想象力。．

二．學(xué)生情況

相對而言，理科班的學(xué)生英語要弱一些，而本篇文章的很多句子和段落的語言不夠清晰明了，對他們來說是有一定的難度的。但由于本文涉及到了蜜蜂的舞蹈，是屬于動物學(xué)的問題，從內(nèi)容上看應(yīng)該是理科班的學(xué)生更感興趣的話題。

為了使學(xué)生更好地理解本篇文章，達(dá)到教學(xué)目的，就必須通過將抽象的語言用圖片或動畫表現(xiàn)出來以減小語言上給他們帶來的壓力，同時又要激發(fā)他們原有的對動物的興趣。
