考纲及课程标准研读

动词的时态和语态是历年高考英语测试的重中之重，一般占1-2道题。命题思路有三：一是直接给出标志性时间状语，考生能依据所给时间状语作出选择；二是给出时间状语，但所给时间状语有着较强的干扰性，考生不能直接根据时间状语作出选择，需要结合语境判断;三是没有任何时间状语，需要借助于上下文语境，才能作出正确判断。

考生应熟知常用时态和被动语态的构成及用法。高考题往往不会涉及单一的时态语态，而是更多地侧重于时态的交叉使用和呼应及与语态的结合使用。所以解题时一定要结合语境，弄清时间的先后关系，可根据不同情况采取找标法(寻找时间标志词)、呼应法(主从句时态呼应)、搭配法(固定搭配)、语境法等解题技巧。

教材分析与学情分析

教材分析：

（1）本节课内容是人民教育出版社 New Senior English for China, Student's Book 2, Unit 3 Computers —Learning

about language －the Present Perfect Passive Voice .

（2）课前学生已在前几堂课复习了其他时态的被动语态，为本节课语法点的学习做了铺垫。另外，在本单元的Warming up 和Reading中学习了与现在完成时态的被动语态有关的一些内容，这为本节课步骤2和步骤3 的活动设计提供了话题。

（3）现在完成时态的被动语态比较容易掌握，因此可以在完成教材所提供的学习任务的基础上，增加在真实交际中综合运用语言的实践活动，如写报告、计划书等。

学情分析：

（1）高一学生在前面的课程教学中已学习了一般现在时、一般过去时、一般将来时的被动语态，而现在完成时态的主动语态和被动语态又有一定的联系，所以对于学生来说也不是太难掌握。

（3）学生已有一定的自主学习能力，在课内活动中能积极配合教师的教学，有较强的提高英语能力的愿望。
