你好, ghada, here is the explanation,

1. 把 can be used when you want to deal with or to dispose of a particular object.
2. A verb in the 把 construction changes the form, situation or direction of the object.
3. Verbs in 把 constructions are in complex forms. They are usually verbs of method of action plus other elements.

4. 把 can be used when you want to specify that the result of an action affects a particular object, but not the action itself.

5. When a sentence has both a direct and an indirect object connected by a verb plus a complement, the 把 construction is used.

Let me know if you have any other questions.
