Present Perfect Tense Endings

The endings for the present perfect tense in English are formed using the auxiliary verbs "have" and "has" followed by the past participle of the main verb. The endings for the auxiliary verbs "have" and "has" are as follows: - "have" is used with "I," "you," "we," and "they." - "has" is used with "he," "she," and "it."

For example: - "I have already eaten my dinner." [[1]](https://skyeng.ru/articles/dlya-chego-nuzhno-vremya-present-perfect/) - "He has gra..." [[1]](https://skyeng.ru/articles/dlya-chego-nuzhno-vremya-present-perfect/)

These examples demonstrate the use of "have" with "I" and "has" with "he."
