I am trying to 'conjure up' a chart on result, reason, purpose, and contrast for my students, and I am really hard put to come up with a satisfying adverb to introduce the sentence mentioning the reason for something.
Result: I work hard. Therefore, I am successful. (adverb introducing the sentence mentioning the result)
Reason: I am successful. Naturally, I work hard. (adverb introducing the sentence mentioning the reason)
Is there an adverb other than 'Naturally' for reason, as obvious as 'As a result/Consequently/Therefore' for result?
I have thought of 'Obviously', 'Evidently', 'Of course', but they are hardly more satsifying than 'Naturally', aren't they?
