《Online tours》PPT，第二部分内容：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,如:
They built a new bridge over the river.
被动语态表示主语是动作的承受者,如:
A new bridge was built over the river.
当主语是动作的执行者时,随后的动词用主动态;当主语是动作的承受者时,随后的动词用被动态。英语动词的主动态是没有标记的，而被动态则是有标记的，通常由助动词be + 及物动词的过去分词构成。

《Online tours》PPT，第五部分内容：Conclusion :
一、主动语态变为被动语态
把主动语态的宾语变为被动语态的主语,用主格把谓语变为被动结构,注意be 的时态和原句要保持一致。把主动语态的主语放在介词by后作宾语，将主格变为宾格。
二、被动句变为主动句的步骤:
1) 找到动作的执行者(常为被动句的宾语)作主动句的主语.
2) 找到be+过去分词结构还原为及物动词原形.
3) 找到动作的承受者(常为被动句的主语)作主动句的宾语.
4) 确定及物动词的时态。数(注意)在以上转换中,代词作主语用主格, 代词作宾语用宾格.
