I'm holding the Hosta flower picked from my flower pond, and I'm going to give it to my dear teacher Han.

The abbreviation should be: Hosta flower in hand, for teacher Han.

Note that "I" is the attribute, so delete it; "Picked from the home flower pond" is an attribute, deleted; "Prepare" as an adverbial, and delete; "Dear" is an attribute, so delete it.

This sentence is a continuous sentence.

I hope I can help you!
