English Grammar -- Present Perfect -- Structure -- TESOL
This video is the first of two that looks at the structure of the Present Perfect tense. Positive: subject +auxiliary verb have/has + past participle I have played. / She has played. Negative: subject + auxiliary verb have/has + not + past participle I have not played. / She has not played. Question: auxiliary verb have/has + subject + past participle Have I played? / Has she played? This verb tense requires the use of the past participle. With regular verbs the past participle is the verb plus ed, for example work - worked. However there are many irregular verbs that do not follow this pattern and have to be learnt from memory. For example, eat- eaten, drink-drunk, teach-taught. Most good grammar books will provide you with lists of irregular verbs. The tense system is just one of the areas of grammar covered by ITTT's TESOL certification courses. ITTT's courses can be taken fully online, in-class or a combination of the two.
