How do you use verbs and adverbs in a sentence?

Answer 1

adverbs add information about verbs. For example they tell

in what manner - quietly gracefully carefully - or how often - never often sometimes - or to what degree - thoroughly, quickly, slowly etc etc

So if you write a basic sentence like:

I eat some ice cream after school. Then an adverb can give more information about the verb eat eg

I usually eat some ice cream after school.

The adverb (usually) tells us that the action (eat) happens about 50% of the time.

Another example:

The policeman arrested the thief. The policeman quicklyarrested the thief.
