Unit5 What are the shirts made of ?

一、语法点：一般现在时的被动语态

（一）概念：英语中有两种语态：主动语态和被动语态。主动语态的主语是动作

的执行者，被动语态的主语是动作的承受者。

（三）被动语态的句型结构：

Are these dishes washed by my mother?

（四）某些含有被动关系的短语 ：have sth. done = get sth. done 让某事被做

eg:I often have my hair cut.

（五）部分动词，如see、hear、watch、feel、notice等变被动语态时要注意还原

不定式to,且被动语态中的动作执行者可省略

eg: The boss makes us work 12 hours every day.（变被动语态）

We are made to work 12 hours every day.
