The Perfective Aspect of Present Tense

In the last blog I explained that English has only two tenses morphologically speaking. These two tenses are present and past tenses.Today I am treating the perfective aspect of present tense, that is present tense, but perfective aspect. Aspect in English grammar will be discussed in my e-manual .

The following sentences show the present perfect tense so called. 1.He has broken the pot. 2. I have eaten the food.3 . Obi has drunk the water. 4. They have poured out the water. 5. He has bought a dictionary. 6. The mechanic has repaired the vehicle. 7. The tree has fallen down already. The seven sentences above show the the use of the present perfect to show a completed action with current relevance. Th reader should note that verbs in the present perfect tense must be in the past participle. Then the verb 'has' will be added to the main verb to form the perfect expression. For example in No 3 above, the verb ' drink' was used with the auxiliary verb ' has' to form the present perfect tense. Note again that the verb ' drink' is changed to the past participle 'drunk' to become ' Obi has drunk the water' which is the normal present perfect tense. So 'Obi drinks the water' becomes 'Obi has drunk the water' .
