Unit 3 Im more outgoing than my sister. Section A 2 (Grammar focus-3c)汕头市屿北初级中学 陈绿茵教材分析：这是第三单元的第二课时的内容，其中心话题围绕Talk about personal traits and compare people这个题材开展多种教学活动，本节课是本单元的重点，通过听、说、读、写来培养学生综合运用知识的能力，通过有限的课堂实践活动，能准确地用英语在交际中运用本单元的话题对自己与他人进行描述，作出比较并进行判断。并让学生能在“做中学。”通过听、说、读、写来学习比较等级句型，加深对比较等级的语法现象的理解和运用，培养学生综合运用知识的能力能初步运用这一语言结构进交谈，为后面 Section B 的学习打下基础，在本单元中起着承上启下的用。 通过本课时的学习，能培养同学间的友好相处，规范自己的行为，同时能提高他们的观察能力和判断能力，激发他们对学习英语的兴趣和热情，在接近生活常态的交际中能乐于模仿，敢于开口，积极参与，主动请教。在此之前，学生已掌握部分形容词、副词词汇的比较级规则变化。所以，这些对学生来说有一定的基础，掌握起来不会那么吃力。学生学情分析：我们教学的对象是初二学生（以中等生为主），他们学习英语有较强的记忆力和模仿能力，有待培养知识的扩展运用能力。，有较强的求知欲和表现欲，但部分学生存在不自信，羞于表现等思想顾虑，但又希望能得到他人的肯定。因此我在教学活动中尽量让他们参与到活动中来，有更多的机会来说英语，减少他们的恐惧感，缺少丰富的语言基础，对某些任务的完成有一定的难度，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。同时在阅读和书面表达中加以落实，提高他们综合运用语言的能力，使各层次的学生都有所收获。一、教学目标： 1. 语言知识目标：1) 复习巩固形容词的比较形式及对两者进行对比。2) 进一步总结所学的对两者进行比较的句式结构。3) 能运用所学的目标语言，进行说与写的活动，完成相关任务。2. 情感态度价值观目标：学会与朋友友好相处，培养乐观，积极向上的性格。二、教学重难点1. 教学重点：1) 总结形容词及副词比较级的构成方式。2) 进一步总结对两者进行比较的句式结构。2. 教学难点：1) 总结形容词及副词比较级的构成方式。2) 能运用所学的目标语言，进行说与写的活动，完成相关任务。三、教学过程.

Which is better, the red pen or the black pen? Who dances better, you or your sister? 5. 使用形容词比较级时需注意以下几点：1） than后面接代词时, 一般要用主格形式， 但在口语中也可使用宾格形式。 如： My brother is taller than I/me. 2) 当需要表示一方超过另一方的程度时，可以用much, a lot, a little, a bit, even, still等来修饰形容词比较级。注意: 比较级不能用very, so, too, quite等修饰。如：He is much more serious than Sam.2.
