The basic Chinese sentence structure is Subject + Verb+ Object. In the passive structure led by 被, you need to rearrange the sentence elements. The Object (recipient of the action) should be placed before, while the subject is placed at the end of the sentence. The basic structure of 被 sentence is: Subject (Recipient of the action) + 被 + Doer of the action (optional) + Verb  杯子被我打碎了。| The cup was broken by me. 我的手机被小偷偷走了。| My mobile phone was stolen by a thief. 我被老师批评了。| I was scolded by the teacher.
