Present perfect continuous form exercises

To make the present perfect continuous tense we use the auxiliary verb have been/has been and the main verb plus -ing ending. When writing, you should mind the correct spelling of a gerund. In negations, we add “not” after “have”: have/has not been doing. In questions, “have” goes before the subject: have/has + subject + been + doing. The exercises on this page will enable you to practise the formation of affirmative, negative and interrogative sentences in the present perfect continuous tense. They are essential for the further study of this verb tense.
