* 被 动 语 态 详 解 高中英语必修5 Module4 Grammar 山西民贤高中1106班公开课 2012－10－17 (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” “挨”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。以do 为例，列表如下： 一般现在时： am / is / are + done 一般过去时： was / were +done 一般将来时： shall / will + done 一般过去将来时： should / would + 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。 (三)被动语态常用的八种时态 1. 一般现在时： People grow rice in the south of the country.
