簡介：

The verb "to be" has three forms—has been, have been, and had been—used in different tenses. "Has been" is used with singular subjects in the present perfect tense to describe an action or state that started in the past and continues to the present, e.g., "She has been working here for five years." "Have been" is used with plural subjects and "I" in the present perfect tense, describing a similar ongoing action, e.g., "They have been studying all day." "Had been" is used in the past perfect tense for both singular and plural subjects, indicating an action or state that was happening before another action in the past, e.g., "By the time we arrived, she had been waiting for an hour." These forms help convey time relationships between actions and states.
