The “把” (bǎ) construction is a special way to show how we do something with an object. Here are some key points to help you understand it better:

1. Structure: It follows this pattern:
   Subject + 把 + Object + Verb + (Extra Details).
   For example:
   我把书放在桌子上。
   (Wǒ bǎ shū fàng zài zhuōzi shàng.) - This means "I put the book on the table."

2. Focus on Completion: This shows that something is finished.
   For example:
   他把门关上了。
   (Tā bǎmén guān shàng le.) - This means "He closed the door."

3. Works with Certain Verbs: You can only use this with certain verbs that need a direct object.
   For example:
   妈妈把饭做好了。
   (Māmā bǎ fàn zuò hǎo le.) - This means "Mom has cooked the meal."

4. Shows Change: It helps explain how an object has been changed or affected by an action.
   For example:
   我把狗洗干净了。
   (Wǒ bǎ gǒu xǐ gānjìng le.) - This means "I washed the dog clean."

Knowing how to use the “把” construction is important for talking about actions that directly affect objects.
