３、只需强调动作的承受者时要用被动语态，如：

二、把主动句变为被动句的方法：在主谓宾结构中
１、把主动句的宾语变为被动句的主语，主动句的主语变为by短语（没必要时可省），如：Bell invented the telephone in 1876
.２、在主－谓－宾结构变为被动语态时，只将其中一个宾语变为被动句中的主语，另一个宾语不变，如：
3)In one story ,lanternswere lit(light)to celebrate the power of light over darkness.
4)In the old days ,dragon boat raceswere organisedonly(organise) by the Chinese people .
I often hear him sing.
He is often heard to sing.
