The passive with 被

Structure Object + 被 + (agent) + Verb + complement

With 被 (bèi) the affected thing becomes the subject: "X was + past participle (by Y)". 我的手机被偷了 = "my phone was stolen". The doer (agent) goes after 被 and can be dropped: 杯子被打破了. As in the 把 sentence, the verb takes a complement (了, result…). Chinese uses it less than English/Spanish passives, and it often carries a negative or unwanted nuance.

Examples

我wǒ的de手shǒu机jī被bèi偷tōu了le。

杯bēi子zi被bèi他tā打dǎ破pò了le。
The cup was broken by him.
蛋dàn糕gāo被bèi吃chī完wán了le。
The cake was all eaten.
