She said angrily. He said happily. You know the trick instead of doing something like "Get lost,"she said angrily, I learned to her hands fisted. "Get lost." Gives the same meaning but the second version packs a punch and also gives a view of the character.
Adverbs generally end with ly. So that's something to look at while you're in revision mode.There are other adverbs we tend to use. Very is one. She was very sad. Not to mention passive voice, that sentence doesn't give a picture of the character. There are times when I do use this and sometimes repeat the word, especially in dialogue. "I am very, very mad." In a story this was a child speaking. An adult might have said I'm furious. Other adverbs that can creep into a story are ones like almsot, frequently. Just be on the look out for adverby while you're writing.
