PRESENT PERFECT SIMPLE TENSE

Tenses form the backbone of the English language. For this reason, Learners should always keep in mind that English is a chronological language. Thus, English has many verb tenses: some express a connection between two periods, whereas others indicate the exact timing of an activity. Further, the depth of the English tenses should never be underestimated. Indeed, we can express very different things when we simply change the tense. Correct use of tense implies the use of correct form of verb with proper auxiliary. Specifically, in order to form the present perfect tense, we use the word have or has followed by the past participle of the verb. For regular verbs, the past participle is a form of the verb that ends in {-ed}, {-d}, or {-t}.
