Learning about Language教案3

Unit3 Computer Learning about language教学设计

一．教材分析：

Learning about language分词汇（Discovering useful words and expressions）和语法（Discovering useful structures）两大部分。Discovering useful words and expressions 1 根据单词释义写出相对应的词汇，考查学生对WHO AM I? 文章中的重要词汇及短语的理解。2 是以对短文填词完型的形式考查学生对几个重点词汇在篇章中的运用。3 以personalize的形式练习几个表时间状语的短语的用法。Discovering useful structures 是学习现在完成时的被动语态。1 是让学生根据例子提示在WHO AM I?文章中找出两个含有现在完成时的被动语态的句子，初步了解这一时态的形式。2 是根据例句提示把所给的现在完成时句子变为被动语态。3 通过欣赏一首小诗进一步理解现在完成时的被动语态的用法。

主动语态

被动语态

现在完成时

have/has done----------have/has been done 2. 只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place,

die, appear, disappear, fail, remain, lie, last, sit ,stand, break out, come true, belong to等．如：

但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。如：
