Present Perfect

The present perfect simple is used to look back on actions in the past with a connection to the present.

It´s used with this time words : ever - never - before - since - how long - for - just - this - yet – already

We also use the Present Perfect to talk about an imprecise time in the past but as soon as we become precised we switch to the Past Simple.

Present Perfect uses HAVE / HAS followed by a verb in participle form.

PERSONAL PRONOUN HAVE / HAS PARTICIPLE VERB COMPLEMENT I have done my homework You have lived in Teran since 1998. He has come to the house 5 times this year She has fallen in love with you. It has broken the window. We have gone to Mexico several times. They have seen an UFO.

IN NEGATIVE SENTENCES WE JUST ADD THE WORD NOT AFTER THE VERB HAVE / HAS. PERSONAL PRONOUN HAVE / HAS + not PARTICIPLE VERB COMPLEMENT I haven’t finished my homework You haven’t traveled to Europe yet. He hasn’t called me yet She hasn’t taken the exam.

Remember: We use the Present Perfect with: have or has + Past Participle have I We You They has He She It have not has not + Verb in Participle form

FOR AND SINCE

We use FOR and SINCE to say how long something has been happening.

We use FOR + a period of time (two hours, six weeks, etc)

For example:

I haven’t seen you for ages

I’ve been working for two hours .

We use SINCE + the start of a period (8 o’clock, Monday, 1999, etc)

For example:

I have lived in Montemorelos since 1998 .

ALREADY AND YET

We use ALREADY to say that something happened sooner than expected. Already usually goes in the middle of a sentence

For example: I have already listened that CD.

We use YEY mainly in negative sentences (He isn’t here yet) and questions (Is he here yet). YET shows that the speaker is expecting something to happen.

For example: I haven’t travelled to Europe yet.
