新版PEP小学英语四年级上册Unit1BLets-talk教案.doc

2013秋PEP四年级上册Unit1 My classroomB Lets talk教学设计一、 教学内容分析：本课是四年级上册第一单元B部分的对话课，内容包括Lets talk和Lets play两部分，是在学习完有关教室常见物品单词的基础上，结合教室的真实环境来引出新知。重点是通过对话学习，掌握并区分句型Lets clean. Let me clean.并引导学生在生活实际中正确运用。二、 学情分析：我所带的四.九班，大部分学生活泼好动，对英语有着极大的兴趣和热情，乐于参与游戏和比赛等有挑战性的活动，接受能力较强。但是也有少数学生基础较差，没有良好的听课习惯，需要多鼓励，多关注。本课主句型Lets贯穿于教材题目中，三年级就已接触过，应加强与新句型Let me的区别引导，让学生真正理解所学。三、 教学目标语言技能目标：1. 理解对话大意，知道怎样提出行动建议，能用正确的语音语调朗读对话。2. 能够在图片、实物或情景的帮助下，在日常生活中运用句型：Lets. Let me.来提出行动建议。语言知识目标：能够听懂、会说句型：Lets clean the.; Let me clean the. Let me help you. Thank you!情感态度目标：1.学习礼貌言行，能够对请求、道歉等行为做出恰当反应。2.通过学习本课内容，教育学生要热爱班集体，热爱劳动，具有讲卫生、爱整洁的意识。文化意识目标：了解西方国家相互尊重、体谅对方的相关的文明礼仪。学习策略目标：1. 借助PPT，图片创设真实情景，呈现本课时主要句型。2通过听音，模仿，让学生整体感知课文情景，提高学生的听力和模仿水平3. 通过图片再利用，让学生争做卫生小达人，实现句型操练。四、教学重点和难点1.教学重点： 学习区分和正确使用Lets 与Let me的句型，发音和含义容易混淆。学习词组clean the classroom, clean the desks and chairs, clean the window, clean the board.2.教学难点： 区分和正确使用Lets.与Let me.clean在本课中具有两种含义（动词“打扫”，形容词“干净的”），教师要在学生不理解时进行解释。五、教学过程ProceduresTeachers ActivitiesLearners ActivitiesPurposesWarm-up&Review1.Play the song “We have a new classroom”.
