把 & 被 Constructions in Chinese Grammar
Choose 把 when the sentence follows what someone does to a known object. Choose 被 when the affected object needs to be the center of attention.
Choose the structure by meaning
These constructions are about sentence focus and outcome, not word-for-word transformations.

He broke the cup.
把 + Object + Verb

Common mix-ups
When 把 is required or unnatural
bǎ
把 works best with a specific object and a visible result. Avoid it for vague objects or verbs with no outcome.
把门关上 = close the door; 把一个东西喜欢 is unnatural.
bǎ mén guān shàng
把 vs ordinary SVO
bǎ vs normal word order
Use ordinary SVO to state the action. Use 把 when the sentence needs to highlight what happened to the object.
我洗衣服 = I wash clothes; 我把衣服洗干净了 = I washed the clothes clean.
wǒ xǐ yīfu; wǒ bǎ yīfu xǐ gānjìng le
被 with or without the agent
bèi
The agent after 被 can be named, but it can also disappear when the receiver and result matter more.
杯子被他打碎了; 杯子被打碎了.
bēizi bèi tā dǎ suì le; bēizi bèi dǎ suì le
