In building Present Perfect Tense sentences, I will share with you the 3 points that will indicate present perfect tense easily. Those are as follow:
- An action that happened at an indefinite time in the past: John has traveled around the world. (We don’t know when.)
- An action that happened more than once in the past: George has seen this movie three times.
- An action that began in the past and is still occurring in the present: John has lived in the same house for twenty years. (He still lives there.) OR: John has lived in the same house since 1962. (He still lives there).
- Use FOR + duration of time: for five hours, for thirty years, for ten minutes, etc.
- Use SINCE + beginning time: since 1972, since five o’clock, since January, etc.
- The adverbs YET and ALREADY are used to indicate that something has happened (or hasn’t happened) at an unspecified time in the past. These adverbs are often used with the present perfect:
already — affirmative sentences
yet — negative sentences and questions.
Examples of Sentences with “yet” and “already”:
- We have already written our reports. (affirmative.)
- We havent’t written our report yet. (negative)
- Gabriel has already read the entire book. (affirmative)
- The president hasn’t decided what to do yet. (negative)
- Sam has already recorded the results of the experiment. (affirmative)
- Maria hasn’t called her parents yet. (negative).
NOTE: Another option with the use of YET is sometimes possible. In this case:
- the verb is positive — the adverb YET does not appear at the end of the sentence: John has yet to learn the material; We have yet to decide what to do with the money.
- the verb is negative — the adverb YET does appear at the end of the sentence: John hasn’t learned the material yet; We haven’t decided what to do with the money yet.
Up to the present time I have given you some types of tenses: Simple Present & Simple Past tenses; Past progressive (Continuous) tense; Present Perfect Tense.
NOTE: Try to give me examples of sentences (at least 2 sentences of each) using the above mentioned tenses. Please put them in my INBOX MESSAGE on my facebook.
NO TRY NO GAIN.
