第二课时 课时内容 A Let’s try Let’s talk 课时分析 本课时是人教版六年级下册第四单元的第二课时，与第一课时紧密相连，围绕“学校的今昔变化”展开话题。本节课主要通过谈话情境学习词汇one day, look it up, in my time, Internet. 学会如何请求别人讲述关于某一方面的句型 Tell me about…以及继续巩固表达过去某地的样子的的句型There was…/ There were…引导学生关注社会的变化，珍惜现在的生活。学会上网查阅资料，渗透人类首次登月的相关信息，提高学生自主学习的能力，持续培养学习英语的兴趣。在第一课时中句型There was…/ There were…的学习，为本课时奠定了一定的基础。There be句型学生掌握的比较熟练。本课时的重点是词汇的学习和能在情景中运用There be句型，用3~5句话描述某个地方过去与现在的状态和变化。‎ 本课时包括Let’s try 和 Let’s talk 两个板块。Let’s try是听力训练，呈现的是吴一凡的爷爷参观学校、与孩子们对话的材料。通过听力的练习，引出核心句型There be(过去式)，为Let’s talk 对话部分的学习创设语言情景。Let’s talk呈现的是吴一凡的爷爷和孩子们交流学校过去情况的场景。在学校里，吴一凡的爷爷观看学校的照片，引出用There was.../There were…对过去学校的介绍。Sarah从爷爷的介绍中联想到自己想要参观月球的愿望，从而引出人类首次登月的信息。本课时谈论学校情景的话题，贴近学生的生活，真实，有意义，学生们非常感兴趣，满足了学生的求知欲，激发了学生想要用英语表达的欲望，培养学生对英语学习的热情。‎ 本课时出现的词汇one day, look it up, in my time, Internet.意义容易理解，但是用法的运用由一定的难度。在教学中要借助图片，语境帮助学生对词汇的理解和运用。‎ 本课时出现的句型很多。我采用先复习，帮助学生回忆旧知，利用新旧之间的联系引出新知。在学习新知的过程中，要创设语境，学习新知。设置交际性活动、语言训练活动、小练笔等活动巩固新知。教学过程遵循以学生为主体，教师为主导的原则，引导学生自主学习。‎ 课时目标 ‎1. 能够听、说、认读单词：one day, look it up, in my time, Internet ‎2. 能够听、说、读、写句型：There was no library in my old school. ‎ Tell us about your school, please. ‎ How do you know that? ‎ There were no computers or Internet in my time.‎ ‎3. 能够很好的完成Let’s try。 ‎ ‎4. 能够在图片的帮助下，在情景中运用There be句型描述某个地方过去与现在的状态和变化。‎ ‎5. 能够理解对话大意并能正确朗读所学对话。‎ ‎6. 了解人类首次登月的一些信息。学会上网查阅资料。‎ 课时重难点 ‎1.重点 ‎（1）能够听、说、认读单词：one day, look it up, in my time, Internet ‎（2）能够听、说、读、写句型：There was no library in my old school. ‎ Tell us about your school, please. ‎ How do you know that? ‎ There were no computers or Internet in my time.‎ 5‎ ‎（3）能够在情景中运用There be句型描述某个地方过去与现在的状态和变化。‎ ‎（4）能够理解对话大意并能正确朗读所学对话。‎ ‎2.难点 ‎（1）单词one day, look it up, in my time 的用法。‎ ‎（2）能够在情景中运用There be句型描述某个地方过去与现在的状态和变化。‎ 教学准备 ‎ 多媒体课件、词卡、录音机和磁带、图片、家乡照片 教学过程 Step 1 Warm up ‎1.
