‘将’ introduces a future or planned action, often in formal or written contexts, and is followed by a verb phrase describing what will happen.

‘已经’ (or the shorter ‘已’) highlights that an action or state has been completed, similar to ‘already’ in English.

‘不再’ negates future repetition, meaning the action won’t occur again; often paired with verbs to say someone ‘no longer’ does something.

‘未’ is a formal negator used mainly in written language to claim something hasn’t happened or isn’t the case; it’s similar to ‘has not’ or ‘did not.’

This structure frames a range or progression between two points, ideas, or states, showing contrast or development.
