I read about 把 once in a grammar class. Read about it, not practiced it; there’s no meaningful practice in the “40 Fruits School of Language Non-Teaching.” I don’t actually know how to use it in the wild. I do, however, remember the sample sentence: 把門打開。 Open the door.
I remember the explanation; 把’s object is going to be the definite direct object of a transitive verb. So I can theorize 把食物打包， 把禮物給她, but I don’t know if those sentences actually work. I’ll ask.
I feel like the key to a 把 lesson is to have the learner manipulate actual objects in space. So a good activity might be a cooking class. Or putting items away in their spots. Or pulling stuff out of a bag/drawer. That would be the in-the-flesh lesson.
The independent online lesson, on the other hand, would be one of those command based choose your own adventure, text-based role playing games. That would work.
More later… now: breakfast buffet.
