The present perfect tense

I. The formation of the Present Perfect Tense

The Present Perfect is built by means of the auxiliary verb to have in the Present Indefinite and Participle II of the notional verb (with regular verbs the Participle is formed by adding the suffix –ed, irregular verbs are used in the form of Participle II according to the list of irregular verbs).

In the interrogative form the auxiliary verb is placed before the subject.

In the negative form the negative particle not is placed after the auxiliary verb.

I have worked

Have I worked?

I have not worked

You have worked

Have you worked?

He/She/It has worked

Has he/she/it worked?

He/She/It has not worked

We have worked

Have we worked?

We have not worked

They have worked

Have they worked?

They have not worked

II. The contracted affirmative forms are:

I’ve worked

He’s worked

You’ve worked

The contracted negative forms are:

I haven’t worked

He hasn’t worked

You haven’t worked

The negative-interrogative forms are:

Has she not worked?

Hasn’t she worked?

Have you not worked?

Haven’t you worked?

III. The use of the Present Perfect

1. In English we usually use the Present Perfect to talk about actions in the past when we are not thinking or talking about the exact time that they took place. The time is not important. However there may be results or effects now.

Have you met Peter?

(We are not interested in when you met him, only if you have or not.)

Vicky has already eaten her lunch.

(We are not interested in when.)

I’ve broken the window.

(It doesn’t matter when I broke the window. What matters is that now I’m in trouble!)

2. We can use the Present Perfect for longer actions which started in the past and are still happening.

I have lived in Vienna for two years.

(I was in Vienna two years ago. I am still in Vienna now.)

I have worked for this company for over two years.

3. We use the present perfect to show that an action happened during a period of time up to now.

I’ve only seen six tigers.

(In my life up to now.)

Have you been to Denmark?

(In your life up to now.)

This means that we can use the present perfect for actions where the time has not yet finished.

Thursday: I’ve seen two films this week.

(The week has not finished yet.)

4. We use the Present Perfect for an action that happened in the past and may happen again. We can show that something will not happen again by using the past simple.

I have been to the Moscow State Circus.

(And may go again.)

Compare:

I went to the circus last year.

(Now it has left and I can’t go again.)

BEEN and GONE

He has gone to Spain. (He has left and is still there.)

He has been to Spain. (He has visited and come back.)

He has been in Spain for a week. (He left a week ago and is still there.)

5. We can use the Present Perfect with the following “time guides”: just, already, yet, always, ever, never, often, lately, of late, recently, so far, up to now, repeatedly.

Hello, have you just arrived?

I have already started my new job.

We haven’t seen George recently.

They haven’t had any problems so far.

6. We use the Present Perfect after a superlative.

What a boring film! It’s the most boring film I’ve ever seen.

7. We use the Present Perfect with This is the first time…, It’s the first time….

Ron is driving a car. It’s his first time behind the wheel of a car. This is the first time he has driven a car.
