【探究提升】初中被动语态语法讲解

 (一) 语 态 分 类

英语动词有两种语态.，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如：

  They will build a new bridge over the river. (主动)

A new bridge will be built over the river. (被动)

汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用：

助动词be + 及物动词的过去分词构成。

 (二) 被动语态的时态、人称和数的变化主要体现在be的变化上，其形式与系动词be的变化形式完全一样。

一般现在时：am / is / are + done

一般过去时：was / were + done

一般将来时：shall / will + be done

一般过去将来时：should / would + be done

现在进行时：am / is / are + being + done

过去进行时：was / were + being + done

现在完成时：have / has + been + done

过去完成时：had + been + done

将来完成时：shall /  will + have been + done

过去将来完成时：should / would + have been + done 

［注］被动语态没有将来进行时和过去将来进行时。
