Verb Tenses
Present perfect continuous
Emphasize how long something has been going on.
Why this happens
Present perfect continuous (have/has been + -ing) stresses ongoing activity from past until now, but writers use it with stative verbs (*have been knowing) or when simple present perfect is enough (I have been finishing — awkward). It highlights duration and visible effects (look tired from studying). Choose it when the process itself — not just the result — still matters at the moment of speaking.

CorrectI have known her for years.
Teaching note: Know is stative — present perfect known, not continuous.
IncorrectShe has been wrote three chapters.
CorrectShe has written three chapters — or She has been writing the thesis for months.
Teaching note: Been wrote is wrong; match completed count (written) vs ongoing process (been writing).
IncorrectThey have been work all morning.
CorrectThey have been working all morning.
Teaching note: Been needs verb-ing: been working.
