Past events when time is not mentioned

We use the present perfect to talk about past actions or events when time is not mentioned, i.e. we don't say when these events happened.

Just already, yet

We often the present perfect with just, already and yet. We can use just after the verb have to emphasise that these events are very recent.

We use already in positive sentences to talk about actions that we have completed sooner than we expected. Already goes after the verb have.

We use yet in negative sentences and questions to talk about things that we expect to happen soon. Yet goes at the end of the sentence.

Recently

We often use the present perfect with recently to talk about past recent actions.

Today, this week, this month, this year

We can use the present perfect with time expressions when the time we mention has not finished.

Past experiences - never, ever, before

We use the present perfect to talk about past experiences when we don't say or we don't know when something happened.

Never, ever, before

We often use the words never, ever, or before to talk about experiences.

The best thing I've ever done

We can use the present perfect simple with a superlative adjective and ever.

How many times

We can also use the present perfect to say how many times something has happened until now.

Have gone to or have been to?

We say someone has gone somewhere when this person is still away, and we say someone has been somewhere when this person has already come back from that place.

Past simple or present perfect?

When did it happen?

We use the present perfect (NOT past simple) to talk about past experiences and actions when we don't say or don't know when they happened.

We use the past simple (NOT present perfect) when we mention or ask about when something happened, or when the time is known by the speaker and the listener. We often use a past expression ( last week, yesterday, when I was a child, etc.)
