Unit 4　Sharing
教材分析　　　
本單元的話題是Sharing，主要涉及幫助弱者、志愿服務、合作分享等。通過聽、說、讀、寫等各種活動學習相關的語言知識，使學生了解世界上很多地方依然很落后，從而懂得同情，學會分享。了解一些志愿者工作的信息，培養學生互助合作的精神和社會責任感。結合針對短話題的探討激發學生的國際意識，通過各種渠道力所能及地為貧困地區的孩子作出自己的貢獻。
Warming Up部分是一個調查，分成三項任務：首先回顧自己曾經做過的助人為樂的好事，并采訪三位同學；然后，根據調查內容列舉班級同學所做的好事；最后討論volunteer的內涵。通過這些任務，讓學生懂得什么是“幫助”，反思自己是否樂于助人，以及怎樣做才是“志愿者”，由此為后面的短學習做好鋪墊。
Pre－reading是Reading的熱身活動。交代了閱讀的體(letter)和作者(a young Australian woman，Jo)，還根據她在PNG拍的10張照片提出了5個問題，回答這些問題有助于學生加深理解“志愿者活動”的意義。
Reading是一篇Jo寫給Rosemary的信。其中介紹Jo在PNG(Papua New Guinea)的一個小村教書。在她寫給Rosemary的信中，作者描述了該村學校的情況和去一個學生家做客的經歷，使學生感受到PNG的兒童生活處境的艱難，更加珍惜自己的學習機會。
Comprehending是根據短設計的閱讀理解試題。第一個練習要求學生讀懂書信的內容，用表格的形式幫助學生整理書信中提到的關于巴布亞新幾內亞村落生活及風俗習慣的信息，屬于細節題。第二個練習要求學生對中提到的五個現象進行分析，說明原因，屬于細節推理題。第三個練習要求學生通過閱讀分析生活在小村中的積極面和消極面，這個練習進一步地開闊學生的思維，使學生對艱苦的生活有更深的理解。第四個練習要求學生小組活動，討論四個問題，進一步鞏固學生對于內容的理解，并且讓學生聯系自己的實際情況，通過比較校舍、條、生活狀況等方面的問題，引發學生的深層思考，談談自己是否愿意參加志愿者活動。第三、四兩個練習都屬于深層思考的問題。
Learning about Language分詞匯和語法兩部分。其中，第一部分是有關此篇短中的重點單詞和短語。設置了三個練習，一是根據所給解釋從所學詞匯中選擇相應的單詞；二是用恰當的詞匯完成一篇短；三是根據解釋組成詞組，并用詞組編對話。第二部分是有關限制性定語從句的復習。 首先從中找出含有限制性定語從句的句子；然后用定語從句完成句子，對定語從句加以運用；再用含有定語從句的句子回答問題；最后是兩人結對活動，進一步練習使用定語從句。
Using Language是對Reading的延伸。通過閱讀，參與“Give an unusual gift”的活動。這個部分由三個部分組成，綜合訓練學生聽說讀寫四個方面的能力。“讀與說”通過圖結合的方式，介紹了一些特殊的禮品——為窮人和真正需要它們的人選購禮品。閱讀之后，完成兩個練習：回答問題和把禮物名稱和詳細介紹配對。“聽與說”部分是采訪默里大夫的經歷，以聽力訓練為核心設置了四個活動。1.講述一個人的生平，用到了時間表達法；2.通過列表把握聽力中的細節；3.在涉及聽力內容之前讓學生先就有關聽力中的話題進行討論，有助于學生快速并準確地把握聽力內容；4.展開討論，讓學生思考自己將是否愿意像默里大夫那樣做個志愿服務工作者。“寫作”根據“聽與說”中的話題，運用時間表達方式，根據給出的6個方面對默里大夫的情況進行寫作。
時劃分　　　
在對本單元的各部分材料進行分析、整合后，確定了以下六個重點時：
時一：Warming Up and Listening(聽力)
從話題內容和訓練目的看，Warming Up與Using Language中的Listening and speaking比較接近，所以將Warming Up與Listening and speaking的第1、2、3題和Workbook中的Listening以及Listening Task整合在一起，設計成任務型“聽力”，以訓練聽前預測的能力和學習用時間表達方式介紹一個人的生平經歷的方法。
時二：Speaking(口語)
將上一節聽力剩下的部分Listening and speaking中的第4題和Workbook中與上節聽力內容相關的Talking以及Speaking Task整合在一起，設計成“口語”，訓練學生用英語表達自己的觀點，并且說明這樣做的理由。
時三：Pre－reading and Reading(閱讀)
這篇是一個志愿者的一封家書，她在巴布亞新幾內亞共和國的一個小村教書。信中詳細地描述了她所在學校的情況和她去一個學生家做客的經歷。通過這封信，學生可以了解巴布亞新幾內亞共和國各部落的生活狀況和風俗習慣，同時能夠更好地理解志愿者的工作。
時四：Grammar(語法復習)
本單元的語法重點是復習限制性定語從句(Restrictive Attributive Clause)。學生已經學過這個語法點，所以在這節中，首先對限制性定語從句的特征、關系詞做一個簡要回顧，然后通過多種形式的練習，如填寫關系詞、造句和翻譯等，使學生逐步掌握限制性定語從句的用法。這些環節，如開始部分的聽句子、猜同學的游戲和結束部分的翻譯或寫作練習，都充分體現了在語境中學習語法、在語境中運用語法的教學原則。
時五：Reading，Speaking and Writing Task(綜合運用)
這節語言綜合運用把本單元的第二篇和后練習中的寫作練習組合到一起。一方面是由于這篇——“世界上最有用的禮物清單”，內容比較簡單，不需要用一整節完成；另一方面是后練習的寫作任務——給一個被自己資助的孩子寫封信，既切合本單元幫助他人的主題，題目中又已經列出了書信的結構，書信的內容也是介紹自己的學習生活，能夠與學生的實際結合起，學生寫起有話可說。
時六：Summing Up and Learning Tip(總結復習)
復習分成四個板塊，板塊一是復習內容和重要的詞組句型。復習內容可以通過根據關鍵詞組復述、回答問題和學生互批作(用100詞左右寫一篇介紹部落生活和風俗的)等活動完成。這篇作是閱讀的家庭作業，放在此處，既檢查了作業，又有助于的復習。板塊二是復習語言知識，主要是用翻譯、填詞以及句型轉換復習。板塊三是總結和概括語法項目。指導學生完成表格填充、知識樹，使學生在腦海中對限制性定語從句形成一個完整的概念。板塊四是總結。討論分享的意義，讓學生對于本單元的主題有更加清晰完整的認識，并且由生活中的分享談到學習上的互相合作與分享，即Learning Tip的內容。

學情分析　　　
1．學生經過高中階段必修1～選修6的學習，具備了一定的閱讀技能，如查找細節信息，猜測詞義，抓住段落要點和全大意等，在閱讀速度方面也有了較大的提高，這有助于學生較好地完成這個單元的閱讀。同時，在聽、說、寫等方面也有了一定的基礎。
2．這個單元的話題是分享、幫助與合作。對于高二的學生而言，他們的價值觀人生觀已經基本形成，要想通過一個單元的學習，完全改變學生的價值觀，難度比較大，但教師可以通過本單元安排的內容，如閱讀志愿者的家書，了解一些捐助機構的工作，幫助學生認識這個世界，理解互助合作的意義，即在幫助他人的過程中實現自己的人生價值。
3．學生在這個單元的學習過程中需要用到預習策略、搜集分析信息策略、歸納整理策略及高效復習策略等。
