1教学目标

评论

知识目标: 1有关本单元计算机词汇的应用2现在完成时被动语态的形式、结构及常见使用错误。技能目标:在口头和书面的交流中能正确使用现在完成时被动语态,并能自主进行结构的探索和发现。情感目标:1通过自主、合作学习使学生提高语法意识和学习语法的兴趣。2通过练习本单元的语法项目,提高学生爱护公物、恰当使用电脑的意识。

2学情分析

评论

学生在上一单元已经学习了一般将来时态的被动语态,对被动结构有一定了解。通过本单元阅读环节的讲解,又对现在完成时态被动语态有直观的认识。对于高一新生来说,有一定的接受、加工、处理新知识的能力,但在新的情景下运用以学过的知识和技能,解决新问题的能力还需强化。另外对于语法课,学生普遍有重视但抵触的心理,因为他们认为语法课就是枯燥的讲解和记忆,因此对语法的学习兴趣不强。此外,对于现在完成时和一般过去时以及一般现在时的区别是中国学生学习英语的弱项,在讲解这一语法项目是是需要着力解决的问题。而且,现在完成时要求学生对动词的理解更为深入,特别是动词的延续性和非延续性问题,是应用现在完成时中遇到的问题,这些都对学生应用这个语法项目造成了一定障碍。

3重点难点

评论

1学生在大量语言输入中发现、归纳、总结出现在完成时被动语态的结构特征和使用规则,提高学生自主学习、合作探究和学习新知识的技能。2 学生在说设的交互活动中巩固现在完成时被动语态的知识,并在练习中构建现在完成时被动语态的句型。3

现在完成时太中的动词特点,动词的延续性和非延续性会对学生的应用是个难点。4在合适的语境下恰当应用现在完成时,对造句能力不强的学生会有困难,教师应对做支架。
