When to lose them: Adverbs often slow the narration and can be replaced by better words.
1-Adverbs paired with verbs
Examples: walked slowly, said softly, turned gingerly, took suddenly, etc…
Why is it bad? Because rather than using an adverb you can choose a more appropriate verb. The examples above could be replaced with: crawled, murmured, snapped, seized, etc…
2-Adverbs like quite, then, there: often they are superfluous. I use them often in my drafts, but when I edit I always do a word search. For every “quite”, “then”, or “there” I read the word with and without the adverb. If the sentence works either way (80% of the times) I remove them.
