教学内容分析Section A部分主要围绕History of tea这个子话题，运用was/were done结构，用What, how,where,who引导的特殊疑问句讨论我们日常生活中的常见物品的发明时间、地点、用途和如何被发明的。旨在帮助学生了解电视、电话、电脑、小汽车和中国茶叶的发明和简要历史。促进他们善于观察，能通过对物品的历史话题的讨论，树立自己终身学习的目标。
学情分析九年级学生对于发明话题充满了好奇心和求知欲，乐于用自己所学英语知识和积极的态度表述成自己的观点和体会，学生们能进行简单的发明物罗列，那么新的关于发明的词汇的编排和使用要引导和增加；且学生对was/were done结构的使用应该是比较熟悉的和快速接受的，那么“how was it invented ”问句应帮助学生词汇和句型扩展，避免单一。因为大多数学生讨厌枯燥的语法项目，而且到了初三，学生分两划分分化，两极分化比较严重，所以利用多渠道的教学手段就是一个挑战。
目标确定(1)能掌握以下单词：　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)能了解并掌握一般过去式的被动结构的构成形式； (4) 用一般过去式的被动结构谈论日常用品的发明史。 (5)通过学习本单元，激发学生们的学习主动性和学习兴趣，使他们善于观察，养成终身学习的好习惯而不断努力。
重难点能掌握以下单词：　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

教学反思与改进This is the period for listening and speaking practice.Before listening，students talk about the four common things and get the words ready for listening.Then students listen and make conversations.The most important thing is to learn the passive voice in the past tense and teach students past participle forms.We should learn some new words about this topic in 2d.We can get the students to practice the structure “be used for…” “Who was it invented by？” and “It was invented by。整个课时的设计符合任务型教学特点，能使学生快速明了课题的主要话题，顺利完成课本任务。
