一般现在时被动语态的构成： 被动语态是由“be（am/is/are)+及物动词的过去分词（dne）+by+执行者”构成的，若无需强调动作执行者，“by+执行者”部分可省略。助动词be需根据句子主语的人称和数进行相应变化。
Vpp. :动词的过去分词
1、强调动作的承受着，而不强调动作的发出者/执行者。2、表示经常性、习惯性的被动动作。3、描述客观事实、普遍真理的被动状态。4、用于礼貌、委婉的表达，避免提及动作的执行者。
Yur suggestin is highly appreciated.
This kind f fd is sld in supermarkets.
The classrm is cleaned every day.
Light is reflected by mirrrs.
口诀：主变宾，宾变主，谓动变成be dne形，人称、数、格随着变。
主动语态变被动语态的方法：
A prfessinal team animates this scene.
This scene is animated by a prfessinal team.
主动语态变被动语态的注意事项
（1）只有及物动词才有被动语态，因为只有及物动词能接宾语，才能将宾语转换为主语构成被动语态。如happen，appear，rise等词不能用于被动语态。（2）含有双宾语（直接宾语和间接宾语）的主动句变被动句时，可将其中一个宾语变为主语，另一个宾语保留不变。
