Present Perfect

The Present Perfect connects the past with the present. It describes an action that happened at an unspecified time in the past or that started in the past and continues to the present.

Structure

Subject + Have / Has + Past Participle

Subject	Auxiliary	Past Participle
I / You / We / They	have	eaten / gone / visited
He / She / It	has	eaten / gone / visited

Note: Regular past participles end in -ed (worked, played). Irregular ones must be memorized (eaten, seen, gone).

When to use it?

1. Life Experiences (Unspecified Time)

We talk about things we have done in our lives, without saying when.

• I have been to Paris. (In my life, sometime).
• She has seen that movie three times.
• Have you ever eaten sushi?

Contrast with Past Simple (Specific Time):

• I went to Paris in 2018. (Past Simple - we know when).

2. Recent Actions with 'Just'

• I have just finished my homework. (Moments ago).
• He has just arrived.

3. Changes over time

• I have bought a new car. (I have it now).
• She has lost her keys. (She doesn't have them now).

Key Words

• Ever: Used in questions.
  • Have you ever been to London?

• Yet: Used in negative sentences and questions (at the end).
