How it works
把 moves a specific, known object in front of the verb to describe what is done to it and how it ends up. The verb can't stand bare — it needs an extra element (a result, location, 了, a complement), because the point is the effect on the object.
Examples
我把作业做完了。
Wǒ bǎ zuòyè zuò wán le.
I finished (doing) the homework.
请把门关上。
Qǐng bǎ mén guān shàng.
Please close the door.
