Present Perfect tense | Part 1 - Form

Here is an English grammar lesson about the form of the present perfect tense. In this lesson, you will learn the affirmative form (positive), question form and negative form of the present perfect tense. I also explain the contracted forms for the affirmative and negative. The present perfect is formed by a combination of the auxiliary verb "have" in the present followed by the past participle of the main verb. Example: "I have cleaned." The past participle of regular verbs is formed by adding "ed" to the base form. I also give you the spelling rules of forming the past participle of other regular verbs. The past participle of irregular verbs have no rules at all and you must simply learn them by heart when you learn a new verb. Some examples are be - been, find - found, do - done, go - gone. The position of adverbs whne using the present perfect is very important. Generally we place the adverb between the auxiliary verb "have" and the past participle of the main verb. Example "He has JUST left the office." At the end of this English grammar lesson, there are some exercises to test your understanding. If you have any questions, please ask me in the comments section below the video lesson and I will answer. The accent in the video is a British English accent.
