Change of state: using the aspect particle '了' to express it
Explanation
This is the change-of-state aspect, which uses the aspectual particle 了 (le) to indicate a state that has CHANGED or an action that has been completed/come about. An aspectual particle is a function word that goes with a verb/adjective to express the "aspect" of the action.
Subject (the person or thing performing the action, at the start of the sentence) + Verb/Adjective + 了 (le). E.g. 她病了 (she has gotten sick - she was not sick before and now is, so there is a change of state). Negation: use 没 (méi - not yet/not) placed BEFORE the verb and DROP 了. E.g. 她没病 (she is not sick), 他没吃早饭 (he hasn't eaten breakfast). You do not say 没...了.
When emphasizing a change from one state to another, or that something has just happened/been completed.
了 indicating a CHANGE differs from 了 indicating simple completion, but at the HSK1 level both are understood together as "has already...". The negation of 了 is always 没, NOT 不.
Keeping 了 in the negative (wrong: 她没病了). Remember: if there is 没, drop 了.
Examples
She has gotten sick. / She is not sick.
The rain has let up. / The rain has not let up.
He has eaten breakfast. / He hasn't eaten breakfast.
