2º ESO UNIT 8 PRESENT PERFECT

• It’s used when we describe an experience or a change in a situation. In both cases it refers to a situation which started in the past and that, in some way, is related to the present.

I’ve travelled all around the world

• We don’t say exactly when the action happened

She has bought a new house

Since the day I was born till now

We don’t know when she did it but she has a new house

• Let’s compare the previous examples with these ones

I’ve travelled all around the world I travelled to Rome last summer

She has bought a new house She bought a new house in June

What’s the difference?

In both examples you know the time when the action happened, and it was in the past simple

MORE EXAMPLES• I haven't been to Sweden yet.

• My sister has just painted her room pink.

• I've seen wolves in that forest.

• She has lived in London for three years

She is still living there

If you go to that forest now you will see the wolves. They're still there

She started in the past and she has just finished now, in the present

I will go, but since I was born till now I haven’t been there

Tom is looking for his key. He can't find it. "He has lost his key“

He lost it and he still hasn't got it.

• As you can see we use “have” or “has” before the past participle

• So you can talk about an EXPERIENCE you have lived…..– We have been to Paris

• But you can’t not say– We been to Paris – We been to Paris

• We form the negative with “haven’t” or “hasn’t”– I haven’t bought the present for the party

• Ad we use “Never” in the negative form– I have never eaten sushi

No I have never seen that movie / I haven’t seen that movie

Yes I have seen it a lot of times

Yes I saw it yesterday

HOW DO WE MAKE IT?

has

Ever – never
