Unit6 When was it invented Section B1a-1c
[学情分析]
九年级学生经过初中两年的学习，已具有一定的英语综合能力，也积累了一定的英语词汇量，通过本单元前两课时的学习对被动语态已基本知道如何正确表达。学生们对英语学习还保持着较浓厚的兴趣，因此在教学中我应加强知识的强化并培养学生的学习兴趣。同时，该年龄段的学生也很在乎他人的评价，所以在学习过程中我通过鼓励性评价等措施，在教学活动中尽量让他们参与到活动中来，创造更多的机会，鼓励他们多说英语，树立学好英语的自信心。通过学生间的合作学习，降低他们的学习难度，使他们体验到成功的喜悦，从而提高学生的综合语言应用能力。同时，通过此节课，也能了解到地方文化，自己家乡的文化。 [教材分析]
本单元以“When was it invented ?”为话题展开教学活动，中心话题是the inventions,主要语言功能是用一般过去时的被动语态talk about the history of inventions.首先学会恰当地使用一般过去时的被动语态，再学会用被动语态描述各种发明。本部分为第六单元第三课时，是一节听说课，主要学习几个有关食物味道的形容词，并通过听说了解potato chips 的历史。同时，利用当地特色文化—豆腐的发源故事进行拓展，让学生能更好将英语运用到生活实际中。 [目标分析]

其实我们生活中处处充满可以利用的资源，关键是我们如何用心、用脑、用手去做。我国基础教育课程改革的趋势之一是加强课程与学生生活和现实社会的联系。本次课程改革的内容强调联系生活、社会、学生实际，在方法上强调探索、实践、活动，实现课程生活化、社会化和实用化，但这并不是让课程脱离学术轨道，而是让课程和学生生活和现实社会更有效地融合起来，给已有充分发展的学术课程增添时代的源泉和生活的活力。我们有理由相信：怎样有效的把课堂与生活紧密联系在一起，化课堂为生活，融生活于课堂，是一个值得我们老师好好利用却时时困扰我们的话题。只要我们做有心人，充分挖掘生活中的可利用资源。相信孩子们在学习中会获得乐趣，在游戏中获得知识，在课堂中除了学到语言，更多的是学会用语言的方法。真正使英语贴近生活，运用于生活，服务于生活。
