Объяснение:

Present perfectly continues:

have/has been V-ing

I have been waiting

have для I, you, we, they и существительных во множ. числе; has для остальных местоимений и существительных.

V-ing - это глагол с окончанием ing. Do + ing = doing, work +ing = working

Вопросительное предложение без вопросительного слова (без что, где, когда, кто и пр.):

Have/has subject (подлежащее) been V-ing ?

С веосросительным словом:

What/where/why... have/has subject been v-ing?
