This might not be what you are after but have a look at:

When I was a student in grammar school we used to diagram sentences. This was of enormous help to me in developing my writing skills. It is my understanding that this technique is no longer taught in many schools. I believe the answer to your question is to bring back the skill of diagramming sentences to the curriculum in grammar schools.
