The present perfect tense in english and its classification

In this article, I investigate use of the English present perfect tense/aspect by English second language(ESL) learners and its classification by Comrie, Iatridou, Davydova. As indicated in this example, the habitual perfect is another subtype of the extended–now perfect and expresses an eventuality that started in the past and has held regularly up to the present time. He mentions that one diagnostic feature of the English perfect aspect is that it is not allowed to be used together with any phrases indicating a specific time of a past situation, for example, one would not say, “I have got up at five o‘clock this morning”, in which “at five o‘clock this morning” refers to a specific time [1, 54].
