Any action or event of present that is started and finished is regarded as Present Perfect Tense. In a word, it indicates a completed action or event of present. Present perfect tense is one of the most used tenses in English language. We use this tense to express the completed actions of our daily life.
However, now, I am going to discuss over the characteristics and usages of Present Perfect Tense in this lesson along with its structural patterns both in negative and interrogative sentences and the various usages of it. This lesson is the 4th part of All Tenses in English.
Here are some sentences in present perfect tense:
I have joined in this party for your invitation.
He has completed his homework of last class.
So, what have you got from the examples given above. In 1st sentence, the subject ‘I’ has joined in this party. It means that the party has already been completed and the task of ‘joining’ is finished successfully.
In 2nd sentence, you see the action ‘completing homework’ is finished. So, you should now have the clear idea on present perfect tense that this tense always indicates an action or event which has already been finished. The action or event can be considered as past but it is present because the result or effect of that action exists till now.
Now learn the structure of this tense. Yes, it’s simple…
Structure: (have/has+past participle form of verb)
The boy has played cricket today afternoon.
Your little brother has become first in annual exam this year.
Now, you may have a question that where you will use ‘has’ and where the verb ‘have’ in sentences. I have discussed on this term on Present Indefinite Tense also.
Well, if the subject is (3rd person + singular number) such as ‘he, she, it , John, Max, Japan’, you will use the auxiliary verb ‘has’ before the principal verb. But in all other cases such as (3rd person+ plural number)/ 2nd person or 1st person-‘I, we, you, they, all’, you must use the verb ‘have’.
For an example:
I have invited my all friends today.
He has shown the copy signed yesterday.
Now, what’s about the negative and interrogative structures?
Here are the structures, you should study…
Negative Structure: (have/has+ not+ past participle form of verb)
we have not joined in the game because of him.
He has not come on class timely.
So, you just have to add ‘not’ after the auxiliary verbs-‘have/has’ and it will be transformed into negative sentence.
Interrogative Structure: (have/has+ subject+ past participle form of verb+ object+?)
Have we joined in the game because of him?
Has he has come on class timely?
I hope you have now no problem in understanding negative and interrogative structure.
Now, I would like to tell you some important facts of this tense in which you will get the right and authentic direction of the usages of present perfect tense.

Note: Here, you should remember that these words should be placed between the auxiliary verb and the main verb in a sentence.
An exceptional usage of the word- ‘yet’
If you use the word ‘yet’ in a negative sentence, you must place the word at the last of the sentence. Besides, if you use the word ‘yet’ in an affirmative sentence including a (to-infinitive), you have to put the word before the (to-infinitive form)
Here are some examples:
They have not taken the schedule yet.
You have yet to finish the job.
In present continues tense, you have got some ‘Stative verbs’, in which you are not allowed to add (verb+ ing). So, when you will make sentences in present perfect continues tense, the law is same.
In such cases, you have to make those sentences into present perfect tense instead of present perfect continues tense. Because, you are not allowed to add (verb+ ing) after a ‘Stative verb’. If you have not memorized the list of the ‘Stative verbs’, you can get the chart in the lesson on Present Continues Tense.
I have known him for 10 years.
He has been in Rajshahi since 2005.
Note: Here, the verb ‘know’ or ‘be’ is listed under stative verb. So, you will follow the structure of present perfect tense though the other elements in sentence are in present perfect continues tense.
