Many learners of the English language confuse two very important tenses – the simple past and the present perfect. There is no point blaming the learners though, for the confusion lies with the rules governing these two tenses. After all, both these tenses can be used to talk about actions that have happened in the past and are thus now over. Consider the sentences given below:
- I have read ‘Kafka on the Shore’ by Haruki Murakami.
- She ran into one of her school friends this morning. (âRan intoâ is a phrasal verb which means ‘to meet accidentally’.)
- Have you finished your homework?
- My dad has not breakfasted yet.
- He left for work at eight in the morning.
As you can see, each of the sentences given above depicts an action that is already over. If you know the rules of these two tenses, you will immediately be able to figure out that sentences 1, 3, and 4 are in the present perfect tense. Sentences 2 and 5, on the other hand, are in the simple past tense. Also, it is worth mentioning that while sentences 1, 3, and 5 are affirmative sentences, sentence 3 is interrogative and sentence 4 is negative. Anyway, before I explain the rules that govern these tenses and the differences that you ought to keep in mind, let me give you the sentence structure for each type of sentence in these two tenses.
But before you read this post, I suggest you read my post on everything about subject-verb agreement by clicking here.

Let me state categorically that if youâve understood the concept of subject-verb agreement, you will be able to understand whatever is explained here much better. Now, let’s begin with the present perfect tense. Study the chart given below and carefully understand the different sentence structures in order to avoid making silly grammatical mistakes. Keep in mind that these rules are only for sentences constructed in the active voice.

How to identify the subject of the verb in a clause/sentence?
The subject of a verb answers the question ‘who’ or ‘what’.
For example, consider the question given below and its answer.
Question: Who gave us the assignment? Answer: The Mathematics teacher gave us the assignment.
Because âMathematics teacherâ answers the question âwhoâ, it is the subject of the verb âgaveâ in the given sentence.
Nonetheless, if the subject is a non-living thing, it answers the question âWhatâ.
For instance, to the question, âWhat looks beautiful?â one might answer, âThis flower vase looks beautifulâ. Thus, âflower vaseâ becomes the subject of the verb âlooksâ in the given sentence.
How to identify the object of the verb in a clause/sentence?
Objects can answer a number of questions. While direct objects give answers to the questions âwhomâ and âwhatâ, indirect objects answer questions like âwith whomâ, âabout whatâ, âin whatâ, âfor whomâ, etc.
What are adverbial complements?
Adverbial complements are those parts in a sentence that answer the questions, âwhenâ, âwhereâ, and âhowâ. For example, in the sentence, âThey came here on Sundayâ, the parts âhereâ and âon Sundayâ are adverbial complements as they answer the questions âwhenâ and âwhereâ respectively.

What Are the Differences?
Anyhow, the questions that arise now are these: When should we say a sentence in the present perfect tense? And can the present perfect and the simple past tenses be used interchangeably? Well, after having read the points I have given below, you will be able to not only answer both these questions, but also correct the mistakes of others.
#Rule 1
You can use the present perfect tense to talk about an action that is over but without using a time marker that denotes the past. However, if you use a time marker denoting the past, you have to say the sentence in the simple past tense. Study the below-mentioned example sentences to understand this rule better:
- He arrived at the railway station last night.
OR
He has arrived at the railway station. - Did you meet Samantha yesterday?
OR
Have you met Samantha? - I returned to Kashmir in June.
OR
I have returned to Kashmir. - My best friend met with an accident this morning.
OR
My best friend has met with an accident this morning. - We discussed the issue with the manager this week.
OR
We have discussed the issue with the manager this week.
As you will have noted, in the first three examples, the time marker denotes the past; hence, when they are said in the present perfect tense, the time marker is removed. Nevertheless, in the last two examples, the time markers âthis morningâ and âthis weekâ denote the present. Therefore, you have an option to say the sentence in either the simple past tense or the present perfect tense.
Activity #1
Letâs do a small activity now to see if you have understood this point. Identify which of the following sentences given below are incorrect. The answers are given at the end of this post.
- The Prime Minister of India has addressed a gathering in August.
- Their parents attended the meeting today.
- Why have you not completed your work yesterday?
- Havenât you been to Kerala?
- We have understood the lesson.
#Rule 2
We generally use the present perfect tense to talk about actions that have a link with the present. Nonetheless, it is also possible to use the past tense to express such actions. Also, the adverbs âjustâ, ârecentlyâ and âlatelyâ can be used to denote that the action being spoken about happened in the recent past. It is also possible to use the adverb âalreadyâ to denote that the action is completed. However, if the sentence happens to be negative, we oftentimes use the adverb âyetâ provided the sentence is said in the present perfect tense. Look at the example sentences given below:
- Our company has launched a new product recently/lately.
OR
Our company launched a new product recently/lately. - You have not answered my question yet.
OR
You did not answer my question yet. (rare but possible) - Has he already corrected your mistakes?
OR
Did he correct your mistakes? (Since this is an interrogative sentence is the past tense, the adverb âalreadyâ hasnât been used.) - Your male cousin has just provided us with the details of the matter.
OR
Your male cousin just provided us with the details of the matter. - Did you talk to her over the phone lately?
OR
Have you talked to her over the phone lately?
Activity #2
In each of the following sentences, identify the part comprising a mistake. The answers are given at the end of the post.
- Where have (A) you hide your (B) mark sheets (C)?
- Did your mother (A) not attend (B) the meeting already (C)?
- His colleagues (A) have complained (B) about him (C) to the boss yet (D).
- When has the robbery (A) took place (B) according to the police (C)?
- My brother and I (A) did not visited (B) the Taj Mahal on our trip to Agra (C).

#Rule 3
We use the present perfect tense when we talk about how long an action or situation has lasted. These sentences usually contain the preposition âforâ or âsinceâ. Consider the sentences given below to understand this rule better:
- I have lived in Delhi for ten years.
- We have watched ten TV shows since the morning.
- Martha has written ten letters since last evening.
- He has stayed at our place for over five years now.
- Have you not met James since you graduated from college?
It is important for you as a learner to understand that âforâ is used when we talk about a duration while âsinceâ is used when we refer to the start time of an action. Also, notice that in the last sentence âsinceâ functions as a conjunction. The first clause (Have you not met James) is in the present perfect tense, and the second clause (you graduated from college) is in the simple past tense.
Now, letâs do another activity. This activity will help you understand this rule much better. All you need to do is identify which of the following sentences are wrong. The answers are given right after this activity. Some more rules pertaining to these tenses will be discussed by me in one of my forthcoming posts.
Activity #3
- They have played tennis since too long.
- How many poems have you composed since Friday?
- The price of onions has skyrocketed since this party came to power.
- How long have you taught English?
- This story created a lot of impact since it was published.

Answers:
Activity #1
1. The Prime Minister of India has addressed a gathering in August.
Incorrect
Explanation: The time marker âin Augustâ denotes the past. Therefore, the sentences cannot be said in the present perfect tense. The right way of the saying the sentence is: The Prime Minister of India addressed a gathering in August.
2. Their parents attended the meeting today.
Correct
3. Why have you not completed your work yesterday?
Incorrect
Explanation: The given sentence contains an adverb of time (yesterday) that indicates the past. Hence, the right way to say the sentence is: Why did you not complete your work yesterday?
4. Havenât you been to Kerala?
Correct
5. We have understood the lesson.
Correct
Activity #2
1. Where have (A) you hide your (B) mark sheets (C)?
The error is in part B. Use âhiddenâ instead of âhideâ; for with the helping verb âhaveâ, you cannot use a verbâs first form.
2. Did your mother (A) not attend (B) the meeting already (C)?
The error is in part C. Adverb âyetâ and not âalreadyâ is used in negative constructions.
3. His colleagues (A) have complained (B) about him (C) to the boss yet (D).
The error is in part D. This sentence is affirmative, hence, you can use âalreadyâ but not âyetâ.
4. When has the robbery (A) took place (B) according to the police (C)?
The error is in part B. As the sentence has the helping verb âhasâ, verbâs third form must be used. Thus, itâs correct to say â When has the robbery taken placeâŚ?
5. My brother and I (A) did not visited (B) the Taj Mahal on our trip to Agra (C).
The error is in part B. A negative sentence in the past tense contains âdid notâ followed by the verbâs first form.
Activity #3
Except sentences 1 and 5, all are correct. While in the first sentence, the preposition âforâ should be used and not âsinceâ, in the fifth sentence, the first clause should be said in the present perfect tense, i.e., you must use âhas createdâ instead of âcreatedâ.
