syntax

I am currently in a pinch.
I'm supposed to write a script for my Teaching Writing for Secondary School subject.

The topic: syntax. The highlights are 1) sentence structures, 2) sentence boundaries and 3) stylistic choices.

I need to explain these items in a manner that suitable for secondary school students. The script needs to be approved in 4 weeks before I can do video shoot for this stuff. How in Mother Goose's name am I suppose to explain syntactic properties to a bunch of teenagers when I don't even understand the subject itself???

I really hate linguistic courses.
