1、2019-2020學(xué)年高中英語 Unit 2 Sailing the oceans Sailing the oceans教案 新人教版選修9第一部分金色教案教學(xué)設(shè)計說明About the topic and the structures單元話題和結(jié)構(gòu)本單元的話題是“大海航行”，介紹了航海知識和航海探險逸事。通過學(xué)習(xí)學(xué)生應(yīng)該了解：我國歷史上就是航海的先驅(qū)國，自古以來一直處于領(lǐng)先地位，對航海技術(shù)的發(fā)展有著杰出的貢獻(xiàn)。 目前，我國已成為世界上的航運大國，正向著世界航運強國推進。實現(xiàn)航運強國的歷史重任落在你們這一代身上。 本單元還將學(xué)習(xí)“不同動詞形式作謂語”。金色教案教學(xué)設(shè)計在單元課時劃分上與課本保持

2、一致，即“閱讀課、知識課、運用課三課時/三課型劃分”。但在實際教學(xué)過程中，我們建議教師依據(jù)學(xué)生基礎(chǔ)、教學(xué)條件、學(xué)校安排的因素，對課本、對金色教案教學(xué)設(shè)計重新劃分課時、裁剪、拼接使用我們提供的材料，以便“物盡所用”，達(dá)到最佳教學(xué)效果。教師也可以按照我們提出的“實際教學(xué)過程課時劃分建議”進行教學(xué)。Period 1Reading 閱讀課Warming Up 部分教師可以選擇“了解航海家”、“了解鄭和”、“了解馬克 波羅”等形式激發(fā)背景知識、為其后的閱讀作好詞語、結(jié)構(gòu)和心理的準(zhǔn)備。教師可補充：西周天子穆王乘“八駿西行三萬里”（穆天子傳）；孔子率70弟子周游列國；莊王與惠子游于濠梁之上；秦始皇統(tǒng)一中國后

4、航向的精確度,人們稱“牽星術(shù)”。用“牽星板”觀測定位的方法,通過測定天的高度,來判斷船舶位置、方向、確定航線。Reading是篇說明文，說明17世紀(jì)之前西方航海導(dǎo)航技術(shù)。教師應(yīng)引導(dǎo)學(xué)生依據(jù)我們提供的“表格”、“結(jié)構(gòu)圖”等從形式和內(nèi)容兩方面閱讀課文，理解詞語、結(jié)構(gòu)和所述事實。補充：1. 天文航海技術(shù)中國很早就可以通過觀測日月星辰測定方位和船舶航行的位置。鄭和船隊已經(jīng)把航海天文定位與導(dǎo)航羅盤的應(yīng)用結(jié)合起來, 提高了測定船位和航向的精確度, 人們稱“牽星術(shù)”。2. 地文航海技術(shù)鄭和下西洋的地文航海技術(shù)是以海洋科學(xué)知識和航海圖為依據(jù), 運用了航海羅盤、計程儀、測深儀等航海儀器, 按照海圖、針路簿記載來

5、保證船舶的航行路線。航行時確定航行的線路, 叫作針路, 羅盤的誤差,不超過2.5度。Period 2Learning about language 知識課Learning about language首先要求學(xué)生朗讀課文，練習(xí)口語；然后是詞語操練；重點是單元句法“各種動詞形態(tài)作謂語”的學(xué)習(xí)和演練。最后可以引導(dǎo)、示范學(xué)生仿寫閱讀課課文。 Period 3Using language運用課Using language首先引導(dǎo)學(xué)生閱讀一則有關(guān)航海的逸事，其后的聽、說活動圍繞Viking sailings展開, 最后對剛讀過的課文的仿寫活動，可以參考我們提供的范例，引導(dǎo)學(xué)生以學(xué)到的詞匯、短語、結(jié)構(gòu)和話

6、題進行寫作。實際教學(xué)過程課時劃分建議Period 1將Warming Up、 Pre-reading、Reading和Comprehending整合在一起上一節(jié)“閱讀課”。Period 2將Learning about language 和Workbook中的 USING WORDS AND EXPRESSIONS、USING STRUCTURES 整合在一起上一節(jié)“語言知識課”。Period 3將Using language 設(shè)計為一節(jié)包括聽說讀寫單項技能或組合技能訓(xùn)練的“綜合技能課（一）”。Period 4將Workbook 的READING AND LISTENING和TALKING整合

7、在一起上一節(jié)“聽說課”。Period 5將Workbook 的LISTENING TASK、READING AND WRITING TASK和 SPEAKING TASK整合為一節(jié)“綜合技能課（二）”。第二部分教學(xué)資源說明Section 1Background 背景圍繞單元話題“大海航行”我們提供了若干實用性背景材料。這些材料既可以作為教師教學(xué)參考材料為教師所用，也可以直接或改寫、重組后作為課堂內(nèi)外的拓展性閱讀材料呈現(xiàn)給學(xué)生。Section 2Explanation解析重點針對“閱讀課型”中的課文難句，我們提供了詳盡的，就句論句的解析和翻譯，并且以解析的焦點話題為線索，進行了一定的歸納、辨析和

8、總結(jié)，以幫助教師更好地實施“語言形式”的教學(xué)。Section 3Vocabulary詞匯按照課本單元詞匯表順序，我們重點提供動詞、短語搭配的講解。所提供的例句，經(jīng)典、地道、實用、易懂，完全可以直接用于教學(xué)。Period 1 A sample lesson plan for reading(SAILING THE OCEANS)IntroductionIn this period, after the warming up, students will first be guided to learn about navigational instruments.
