英语八年级上册Section A教案及反思

        Unit 3  I’m more outgoing than my sister

                          Section A (1a-2d)   教学重难点

教材分析

本单元是八年级上册Unit 3 Section A的教学内容，以描述某人的个性特征为中心而展开，围绕Talk about personal traits and compare people这个话题开展多种教学活动，从外表和性格两个方面比较人物之间的相同点和不同点，由此引出taller, shorter, thinner, longer, heavier, quieter, more serious, more outgoing等用法，以及“ s + be +  adj.比较级 +  than +  被比较对象”这个重要的句子结构。Section A部分重在从听说角度三个方面比较不同双胞胎之间外表和性格的区别，附带着在3a也提出了 as------as结构 the same as结构来表达两人的相同之处。本节课是一节听说课。学习内容：

1. 学习并自由运用形容词和副词的比较级。
2. 能够运用形容词和副词比较级描述自己看到的人和事物。

学情分析

1. 经过近一年的任务型教学训练，部分学生已经初步养成较好的学习英语的习惯，能够在课堂上听懂老师的教学指令，并且能够根据老师的要求用目标语言完成各项任务。多人小组或二人小组成员有良好的合作意识，能够迅速有效地开展各项活动。
2. 谈人物的特点这一话题学生熟悉且喜欢，学生也具有一定的词汇量，可以用英语进行简单的交流与描述，为本单元即将学习谈论人的个性特征和形容词和副词的比较级做好了准备和铺垫。
3. 比较级对学生来说是第一次出现的新语言知识，学生需要描述和对比人和物，学生在记忆这些新单词时可能会有一定的难度。因此，通过各种方式对新句型与新单词进行反复大量的操练就显得尤为重要。
