The Present Perfect Tense is used to describe actions that started in the past but are still relevant or have an ongoing effect in the present. This tense connects the past with the present, highlighting completed actions that have significance now. It is formed by using “have” or “has” followed by the past participle of the main verb.
What is the Present Perfect Tense?
The Present Perfect Tense refers to actions or events that happened at some point in the past but still have importance now. It emphasizes the connection between the past and present. For example:
- I have eaten lunch tells us that lunch was completed at some point, and the result is relevant now (perhaps you’re not hungry anymore).
- She has visited Paris suggests that the experience of visiting Paris has an ongoing significance or impact.
This tense helps express actions that may not be linked to a specific time, but still matter in the current moment.
Structure of Present Perfect Tense
Positive Sentences
The basic structure for positive sentences in the Present Perfect Tense is:
- Subject + have/has + past participle
For example:
- I have completed my homework.
- She has visited the museum.
In these examples, “have” or “has” is combined with the past participle to show that the action is completed and relevant now.
Negative Sentences
In the negative form, add “not” after “have” or “has”:
- Subject + have/has + not + past participle
For example:
- I have not traveled abroad.
- He has not finished his dinner.
These examples emphasize that the action has not occurred up to the present moment.
Interrogative Sentences
To ask questions, invert “have” or “has” with the subject:
- Have/has + subject + past participle?
For example:
- Have you finished your homework?
- Has she visited the Eiffel Tower?
This structure helps inquire about completed actions that are still relevant now.
Use of “Has” and “Have” in Present Perfect Tense
The choice between “has” and “have” depends on the subject of the sentence:
- “Has” is used with singular subjects such as he, she, it, and singular nouns.
- She has completed her project.
- “Have” is used with plural subjects such as I, you, we, they, and plural nouns.
- They have finished the assignment.
Time Expressions in Present Perfect Tense
The Present Perfect Tense often uses specific time expressions to emphasize the connection between the past action and the present:
- Already: I have already eaten.
- Yet: Has she called yet?
- Just: They have just arrived.
- Ever/Never: Have you ever been to Japan? / I have never tried sushi.
- Recently/Lately: I have recently started a new job.
These time expressions help clarify the timing or relevance of actions to the present.

Rules of Present Perfect Tense
- Formation:
Use “have” or “has” + past participle.- I have studied English for two years.
