Here's an interesting snippet, not taken verbatim, from this part of the course. It's about the mood of verbs - how you convey feeling by the way you use a verb amidst the rest of the sentence.
There are three moods:
1. Indicative - where the verb makes a statement or asks a question:
She creates drama.
Does she create drama?
2. Imperative - gives a command or makes a request:
Have fun now!
Wash your hands in the sink.
3. Subjunctive - ...
The explanation gets a bit hazy here. It sounds like the subjunctive mood is where you are expressing possibility, doubt - stuff that's not a question, statement or direct order. So, like... daydream talk: "Oh, I wish this part of the course wasn't so dry and confusing."
As it stands, I am getting nervous. The assignments I've already handed in haven't yet been marked and returned. I need to work doubly-hard next week to get back on schedule. How excitement! Garr...
