I explained about the Key Verbs, be, do, and have and their inflected tenses in Grammar Activation Pack 1. I have looked at the simple and continuous aspects, both present and past tense in Grammar Activation Packs 2 to 5. In this Grammar Activation Pack, I am going to tell you how the third of the key verbs, have, is used for the perfect aspect, present tense. When a form of the verb have is not followed by a past participle it is acting as a main verb, not an auxiliary verb and the perfect aspect is not formed. We only have the perfect aspect if one of the inflected forms of have comes before a past participle. This British English grammar is essential for all students of English and the many exercises in the pack will help you master it quickly and enjoyably.
