Now that you've completed Sentence Basics Lessons 1 to 5, let's put your skills to work on a sentence from "The Necklace":
He stopped, distracted, seeing that his wife was crying.
There are no prepositional phrases. There are TWO action verbs that have subjects, "stopped" and "was crying," thus there are two predicates.
Who or what stopped? He. He is the subject of stopped. He stopped who or what? There is no answer so there is no DO.
Who or what was crying? Wife. Wife is the subject of was crying. Wife was crying who or what? There is no answer so there is no DO.
"Distracted" looks like a verb, but it has no subject, so it is not a predicate. "Seeing" also looks like a verb, but it also has no subject, so it is not a predicate.
