Unit 10 SectionA1a-2d课件2023-2024学年人教版英语七年级下册

I'd like some noodles. Section A Unit 10 What do you want to have for lunch? I want to have… 导入 思考： I want a cup of tea.(同义句) I _______ ____ a cup of tea. would like want = would like 想要 说课：先通过活动探究，帮助学生理解手性分子的要点；再引导学生观察左右手同样是互为镜像关系且无法重叠的特点强化记忆手性分子的要点。 上课： 每个小组的桌面上都有一个已经组装好的有机物分子模型，不同颜色的小球代表不同的原子或原子团，黑色的小球代表碳原子：①把分子模型放到镜子面前，我们能在镜子中看到其镜像；②把看到的镜像制作成模型。大家开始动手制作。 同学们已经全部完成模型的制作了，请大家观察实物与模型，思考这样一个问题：互为镜像的两个分子，你认为是同一种分子？还是不同的两种分子？——有的同学认为是一种分子，有的同学认为是不同的两种分子。 有什么方法可以证明谁说的对呢？ 我们可以用重叠的方式进行验证，如果实物与镜像可以完全重叠，两者就是同一种分子，如果不能完全重叠，就是不同的两种分子。下面同学们请将实物与镜像从任意方向进行重叠，看看结果如何。 大家操作完得出的结论是什么呢？——实物和镜像不能完全重叠。 既然这两种分子无法完全重叠，那它们到底是什么关系呢？ 像这样互为镜像、无法重叠的两个分子，互称为手性异构体。就像我们的左右手一样（互为镜像、却无法重叠）。 下面我们一起来看下手性异构体完整的定义： 3 4 would like 想要，它与want有区别吗？它都有哪些用法呢？ 含义 用法 区别 would like 想要，愿意 后接名词、代词宾格或动词不定式 would like 比want语气委婉；表达也比want正式规范。 want 想要；打算；应该等 后接名词、代词宾格或动词不定式 知识讲解 说课：先通过活动探究，帮助学生理解手性分子的要点；再引导学生观察左右手同样是互为镜像关系且无法重叠的特点强化记忆手性分子的要点。 上课： 每个小组的桌面上都有一个已经组装好的有机物分子模型，不同颜色的小球代表不同的原子或原子团，黑色的小球代表碳原子：①把分子模型放到镜子面前，我们能在镜子中看到其镜像；②把看到的镜像制作成模型。大家开始动手制作。 同学们已经全部完成模型的制作了，请大家观察实物与模型，思考这样一个问题：互为镜像的两个分子，你认为是同一种分子？还是不同的两种分子？——有的同学认为是一种分子，有的同学认为是不同的两种分子。 有什么方法可以证明谁说的对呢？ 我们可以用重叠的方式进行验证，如果实物与镜像可以完全重叠，两者就是同一种分子，如果不能完全重叠，就是不同的两种分子。下面同学们请将实物与镜像从任意方向进行重叠，看看结果如何。 大家操作完得出的结论是什么呢？——实物和镜像不能完全重叠。 既然这两种分子无法完全重叠，那它们到底是什么关系呢？ 像这样互为镜像、无法重叠的两个分子，互称为手性异构体。就像我们的左右手一样（互为镜像、却无法重叠）。 下面我们一起来看下手性异构体完整的定义： 4 活动与探究（温馨提示：规范操作、注意安全） 知识讲解 would like 常用词组 01 would like sth. 02 would like to do sth. 03 would like sb. to do sth. 6 01 I would like sth. 想要某物 I would like some eggs. 02 would like to do sth. 想要去做某事 03 would like sb. to do sth. 想让某人去做某事 We would like to play games. I would like you to clean your room. 知识讲解 ——说课：完成教学后，设置了两道检测题检测教学效果，检测学生是否已经掌握手性异构体的要点和手性分子的结构。 ——上课：1.下来说法不正确的是（C） 解析：手性异构体互为镜像，不能重叠，组成和原子排列完全相同，所以ABD正确，C错误。答案选C。 6 7 would like 常用句型 Would you like ......?（你想要......吗？） Would you like an ice-cream? 2 1 肯定回答：Yes,please. Sure… 否定回答：No,thanks…. 知识讲解 难点突破 ——说课：完成教学后，设置了两道检测题检测教学效果，检测学生是否已经掌握手性异构体的要点和手性分子的结构。 ——上课：1.下来说法不正确的是（C） 解析：手性异构体互为镜像，不能重叠，组成和原子排列完全相同，所以ABD正确，C错误。答案选C。 7 What would you like?
