Er, bein' Southern and all, this may not be accurate, but as I would do it. 1)Press the keys as indicated by the book. I think some of the words are superflous, and tend to obscure what you're trying to say. 'do it' works fine in a trailer park, anything outside the lot would be 'does it'..;)
- Physically, darkness is a lack of light..and hence has no 'speed' to speak of..having said that, I think 'darkness' would work better, because with dark, the logical question is 'dark what?'
- He wanted to leave as quickly as possible. Quickly and leave are connected. I believe quickly is an adverb, which takes 'ly' to reinforce this.
- I think 'beating' works here, you could use 'beat', but you'd have to add another 'as'. ..beat as slowly as a hawks' (the hawk owns the wing, so it would be possessive, with the ' at the end..
- Brushing and caressing work here, because you're in the present tense, or possibly another fancy English tense I don't know the name of..;) the 'ed' indicates a past tense.
Having said all that, all h-e-double-toothpicks is going to come down on me for some most-likely glaring grammatical errors (strangely enough, the passage of 30 years has made my grasp of grammer a bit rusty).
Should you want to learn what to use in style of grammar, etc., go to your nearest local used book store, and ask for a Style Manual (I think there's a Chicago, possibly a Strunk? ..help me out folks). It will have all your questions answered, although it makes for some dry reading..;) Hope this helps.
