1、人教版高中英语必修3Unit 4 Astronomy: the science of the starsPeriod 5: Subject Clause and Writing主语从句及写作 教学设计 昆明市外国语学校 张彦杰人教版高中英语必修3Unit 4 Astronomy: the science of the stars Period 5: Subject Clause and Writing 主语从句及写作（p29）教学设计 昆明市外国语学校 张彦杰课标分析 高中阶段的英语课程是义务教育阶段课程的自然延伸，是基础教育阶段课程的重要组成部分，为了有利于学生个性和潜能的发展，在设计和实施
2、高中英语课程中，多采取有利于学生优化英语学习的方式，使他们通过观察、体验、探究等积极主动的学习方法，提高自主学习的能力。同时，也要关注学生的情感，使学生在英语学习的过程中，提高独立思考和判断的能力，发展与人沟通和合作的能力，树立正确的人生观、世界观和价值观，增强社会责任感，全面提高人文素养。教材分析： 本单元语言学习部分是由“词汇学习”和“语法学习”两项内容组成。本节课是本单元的“语法学习”部分。“语法学习”部分采用先发现后应用的学习方法，能帮助学生了解、熟悉并初步掌握名词性从句做主语的用法。学情分析：本节课是高一下学期第四单元语法部分关于主语从句的教学内容，学生在第四单元的学习中，已经积累了
