We can talk about finished actions using both the present perfect and the past simple. It’s logical that anything which is finished must be in the past. What the present perfect does that the past simple cannot do is to form a connection between the past finished action and the present. We can only use a finished time expression like last week with the past simple. In this Grammar Activation Pack, I want to focus on how the present perfect connects events in the past with the present. As I said, logically anything that is finished must have happened in the past. The present perfect uses the present tense of the finite verb have, which as you know is have or has, and the past participle of a non-finite verb. It is this combination of the present and the past that gives us our biggest clue as to how the perfect aspect and the present tense work together. 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.
