🔰 Beginner Level

What is Present Perfect Tense?
It connects the past and the present. Something happened before now, but the exact time is not important.

---

🔹 Structure:

• Positive: Subject + have/has + past participle
  Example: I have finished my work.
• Negative: Subject + have/has not + past participle
  Example: She has not eaten breakfast.
• Question: Have/Has + subject + past participle
  Example: Have you seen that movie?

---

🧠 Use “have” with: I, you, we, they

🧠 Use “has” with: he, she, it

---

✍️ Fill in the blanks:

1. I ___ (finish) my homework. → have finished
2. She ___ (not see) the film. → has not seen
3. ___ you ever ___ (try) sushi? → Have you ever tried sushi?

Subtle Differences

Present Perfect	Past Simple
I have seen it.	I saw it.
Looks back from now without a finished past-time reference	Places the event in a finished past-time frame, stated or understood
May describe a finished action or a continuing state	May describe an event whose consequences still matter now

---

🔹 Advanced Uses

• With just/already/yet:
  She has just arrived.
  I’ve already done that.
  Have you eaten yet?
• With since/for:
  We’ve lived here since 2010.
  I’ve worked here for 3 months.

🧠 Summary

Use Present Perfect When…
Action affects the present
Life experience is viewed up to now, rather than in a finished past-time frame
Check the intended time frame: a time expression alone does not select the tense

Present perfect or past simple?

Use the past simple with a finished past-time expression: “I finished the report yesterday”, not “I have finished the report yesterday”. Use the present perfect to connect a past event with now: “I have finished the report, so it is ready to send”. A past-simple event can still matter now; the difference is not simply “relevant” versus “irrelevant”.

For a continuing situation, “since” gives the starting point and “for” gives the duration: “We have lived here since 2020”; “We have lived here for six years”. In conversation, American English often uses the past simple with “just”, “already” and “yet” where British English commonly uses the present perfect.

Choose the tense from the situation

Decide whether the speaker gives a finished past time or looks back from now. A sentence can mention a present consequence and still use the past simple.

1. Yesterday, I ___ (send) the application.
2. I ___ (finish) the application, so it is ready to send now. Use the present perfect.
3. We have lived here ___ three years. Choose for or since.
4. Correct: “She has wrote two emails today.”

Check the explanation

1. Sent: yesterday places the action in finished past time.
2. Have finished: have + past participle links the completed work with its availability now.
3. For: three years is a duration; since introduces a starting point.
4. She has written two emails today: written is the past participle. This presents today as an unfinished period.

Continue with time expressions and prepositions. Reference: British Council: present perfect.
