In Chinese passive constructions, prepositions are commonly used in front of a doer/agent as the indicator of passive voice. The most common prepositional passive marker is bei4被. Such markers as rang4让 “to let”, gei3给 “to give”, jiao4叫 “to call” can be used interchangeably. For examples:
弟弟天天都被妈妈骂。 “Little brother is scolded by mother every day.”
她昨天让老师批评了。 “He was criticized by the teacher yesterday.”
这小孩怎么老给人家欺负。 “How come this child is always bullied by the others.”
我又叫同学笑了。 “I was laughed at by fellow students again.”
