課型 新授課 復習課 試卷講評課 其他課
教學內容分析Section A部分主要圍繞History of tea這個子話題，運用was/were done結構，用What, how,where,who引導的特殊疑問句討論我們日常生活中的常見物品的發(fā)明時間、地點、用途和如何被發(fā)明的。旨在幫助學生了解電視、電話、電腦、小汽車和中國茶葉的發(fā)明和簡要歷史。促進他們善于觀察，能通過對物品的歷史話題的討論，樹立自己終身學習的目標。
學情分析九年級學生對于發(fā)明話題充滿了好奇心和求知欲，樂于用自己所學英語知識和積極的態(tài)度表述成自己的觀點和體會，學生們能進行簡單的發(fā)明物羅列，那么新的關于發(fā)明的詞匯的編排和使用要引導和增加；且學生對was/were done結構的使用應該是比較熟悉的和快速接受的，那么“how was it invented ”問句應幫助學生詞匯和句型擴展，避免單一。因為大多數學生討厭枯燥的語法項目，而且到了初三，學生分兩劃分分化，兩極分化比較嚴重，所以利用多渠道的教學手段就是一個挑戰(zhàn)。
目標確定(1)能掌握以下單詞：　ruler，boil，remain，smell，national，trade，doubt，fridge，low，somebody，translate，lock，ring，earthquake，sudden，bell，biscuit，cookie，musical，instrument ,by accident，take place，fall into，make tea，less than，without doubt，all of a sudden(2)能掌握以下句型：Did you know that tea was invented by accident 　Most people believe that tea was first drunk about 5，000 years ago.　It is said that…　It is believed that…　In England，tea didn't appear until around 1660.(3)能了解并掌握一般過去式的被動結構的構成形式； (4) 用一般過去式的被動結構談論日常用品的發(fā)明史。 (5)通過學習本單元，激發(fā)學生們的學習主動性和學習興趣，使他們善于觀察，養(yǎng)成終身學習的好習慣而不斷努力。
重難點能掌握以下單詞：　ruler，boil，remain，smell，national，trade，doubt，fridge，low，somebody，translate，lock，ring，earthquake，sudden，bell，biscuit，cookie，musical，instrument ,by accident，take place，fall into，make tea，less than，without doubt，all of a sudden
