Oookay, I actually think I should shut up now, because that's going to turn into an unpleasant competition with your book - unpleasant for you, because we're going to contradict each other, trying to go at our own paces. But yeah, as I said in my previous post, there are nuances, among them dependent clauses which completely flip the word order around... And to be honest, based on my experience, I wouldn't worry about it too much if I were you. It took me ages to get the various word orders... I mean, I'm still getting it... Maybe you'll do better, but I haven't found a very simple rule to all that. Some conjunctions flip it, some don't, and also they change the way verbs are conjugated.

All in all, the book probably did its best. And yeah, you said it... Well, not just verbs, a lot of it is confusing, like a language with a many-thousand year history should be.
