再通过分析，总结出这几个句式在不同环境中正确运用的句型：句1里的is thrown into中的is，说明是一般现在时的被动语态句型。句2里的was written中的was，说明是一般过去时的被动语态句型。句3里的will be/is going to be bought中的will be/is going to be，说明是一般将来时的被动语态句型。句4里的must be cleaned 中的must be，说明是含情态动词的被动语态句型。总结如下：

一般现在时的被动语态结构：be(am/is/are)+done

一般过去时的被动语态结构：be(was/were)+done

一般将来时的被动语态结构：will be/be going to be+done

含情态动词的被动语态结构：情态动词+be+done

--2让学生分析、了解主动语态与被动语态的关系。

教学过程实录二：

运用大家都熟悉的人物莫言和babysit这个同学们都感兴趣的内容作为话题，直观形象地对比、分析主动与被动语态之间的联系。如：

例1.Mo Yuan writes many local novels.（主动语态句型）

变被动语态的步骤是：将主动语态句子中的宾语many local novels(也叫，动作的承受者)变为被动语态句子中的主语，再将主动语态句子中的主语Mo Yuan(即是，动作的实施者)变为被动语态句子中的宾语，并在其前加by。

当然这时主动语态的谓语动词也要相应变为被动语态要求的be+done结构。因为novels 是复数，所以be动词选are,即主动句中的writes在变为被动句时，就变成了are written。句子变成了：Many local novels are written by Mo Yuan.这样，主动变被动的句子就完成了。

例2.Jenny must babysit her sister on weekends.

模仿刚才的变化规则：主动语态句子中的宾语her sister变为被动语态句子中的主语，那Jenny就变为被动语态句子中的宾语，还要加by。

那谓语动词的相应变化就是把must babysit变成must be babysat 。

on weekends作为句子中的状语，按规则不发生改变。这样，句子就成为：Jenny's sister must be babysat (by her) on weekends.

从而总结出主动句变被动句的变化规则：

宾变主；主变宾，用by连；谓变被；状不变。

--3让学生分析、了解主动语态句式里出现双宾语的时候，如何更改为正确的被动语态。

教学过程实录三：

充分运用双宾语常用的话题，这里选择了买礼物和发邮件两个内容，分析出双宾语的句型可以变成两个宾语分别引导的被动语态句型，再用微课形式呈现出来。

Brother bought me a cool watch for my birthday。（主动语态句型）

句中出现了双宾语： me(间接宾语) 和a cool watch(直接宾语)。首先先把主动语态中的宾语me作为更改的对象，这时，直接宾语a cool watch不需要改变，如此，句子就成了：

I was bought a cool watch for my birthday (by my brother).

接下来再把间接宾语作为被动语态句子中的主语，这时我们就要判断谓语动词的固定短语搭配，比如，我们所学(买东西给某人)的句式是buy sth. for sb.就是说间接宾语在更改后的句子中，由for连接。其它部分都与主动语态变被动语态的规则一样。句子就成了：

A cool watch was bought (for me) for my birthday (by my brother).
