高中英语-Unit4 Astronomy教学设计学情分析教材分析课后反思

课标分析一、语言知识（Knowledge）语法(Grammar)掌握和运用主语从句。如1.Whatisneededforthespacetripiscarefulpreparation.2.Whythereisgravityishardtounderstand.二、语言技能(Skills)能熟练掌握与话题相关的常用词汇与语法表达，如何通过英语来正确客观地表述问题及给予意见，同时使学生能就话题较好地完成一些开放性话题，以提高在真实语境中的英语交际能力。能通过输入对本单元内容有一个较好的输出。三、学习策略(Strategy)学生能在一定程度上形成合作学习、自主学习、有效交际、信息处理和英语思维的能力。四、情感态度(Affect)(1)让学生了解生命的起源，增强其保护地球的意识。(2)培养学生正确的阅读观和良好的阅读习惯，加强其自主阅读的能力。(3)培养学生科学探索的精神。(4)培养学生合作和共享的学习态度。教材分析本节课是本单元的“语言学习”（Learningaboutlanguage）部分，有词汇和语法两部分。第一部分练习让学生学着去应用课文中出现的词语。第二部分是针对主语从句的练习，其中第一题要求学生从课文中找出三个或更多的主语从句；第二个练习以把主语从句改写成简单句的形式让学生能对此语法有深层的了解。第三个练习则以完成句子的方式要求学生更进一步的运用复合句，此部分是对表语从句进行练习。学情分析高一下学期同学们已经学习了定语从句以及宾语和表语从句的知识，对从句的知识已经有了部分了解，但是需要反复的练习和巩固。对高一学生来说，语法基础知识还是比价薄弱，因此在学习本单元主语从句上还有不少同学存在困惑。所以要求学生做到充分的预习及其查阅资料，获得一定的语法知识。而且，教师必须给予指导，督促学生养成良好的学习习惯，如预习，记笔记，逐渐发展和完善学习策略。我们教师在教学设计以及教学过程等方面应突出以学生为主体的思想所任教的学校学生英语基础相对比较薄弱，应该有梯度的设置任务，使用分层教学，提高学生的参与度，使不同层次的学生有机会展示自己，获得成就感，体验学习的快乐。如何激发学生的学习兴趣也很关键，不仅在课堂中要有大量情景的设置，而且在课外也要与学生进行情感交流，亲其师，信其言。
