Present Perfect (Unit 16)

[Sunny]

The Present Perfect

How to build it

Subject + to have + past participle

The past participle
When employing regular verbs, you just have to add ‘–ed’ to the infinitive.
Examples:
to close – closed, to call – called, to cook – cooked

When employing irregular verbs, you take the past participle – usually the third form listed.
Examples:
to write – written, to take – taken, to bring – brought

So a Present Perfect sentence looks like following:

I have closed the door.
You have called the doctor.
He has cooked dinner.
She has written an article.
It has taken the newspaper.
We have brought a present.
You have watched TV.
They have worked hard.

When to use the Present Perfect

There are several words that indicate the use of Present Perfect, such as ‘yet’ ‘not…yet’ ‘since’ ‘for’ ‘already’ ‘just’ ‘ever’ .

You employ this tense when you want to show that the incident you describe has happened in the past and is still the case now. The exact time is not important.

Example: He has already been to London.
--> which means: he went to London at sometime in the past and today he can still say: 'I have been to London.'

Or: She has lived in Japan for twelve years.
--> which means: she went to Japan sometime in the past and is still living there. The action started in the past and has not finished yet.

Hi Sunny! I had difficulties with understanding perfect tense. My understanding was not clear after finishing my school. Now it is more better.
May I rely on you ( You should continue with Tenses)

Hi, sunny.

Since elementary, I have found the perfect tenses of the verb hard to grasp. What a relief to know that this thread exists.

Anyway, I have a question:

What is the difference between these sentences:

She has danced for 30 minutes. (Present Perfect)
She has been dancing for 30 minutes. (Progressive Perfect?)

Do these sentences imply one thing: That 30 minutes has passed and she is still dancing until now? please. enlighten me.

[Sunny]

Good question! :D

[Karina]

Yes, it does!!
Bull`s eye! :lol:

Hi Sunny,

I have also some question regarding Present Perfect Continuous Passive Sentences.

After reading your article i recalled the basic rule for Persent Perfect Continuous Tense i.e.

Subject + to have +been +verb(ing from)

But what happen if any other word come instead of past participle for examples,

He has been back at work.
The patient has been in a Cam walker.
He has been able to recover.

I am quite confuse about these sentences structures which i frequently use.

[Alan]

Hi,

The examples you have given are the Present Perfect Simple of the verb 'be'. In the same way also my previous sentence uses the Present Perfect Simple of 'have'.

Thanks Alan,

I will go through for Present Perfect Simple Tense again for recalling.

Would you help me by giving an idea to avoid any confusion on Persent Perfect Tense.

Once agan thank you.

Hi,

One of the devices I used when I was classroom teaching to explain the Present Perfect Continuous was to refer to it as the 'umbrella' tense. In other words it covers three times: the past, the present and the future as in: I have been learning French for 5 years. This means I started 5 years ago (past). I am learning it now (the present) and I am going to continue learning it (future).

Hi,

Once again thank you,

I am wondering now are these given sentence are passive sentences or not. If yes in what form they will be in active voice.

He has been back at work.
The patient has been in a Cam walker.
He has been able to recover.

And also in which sense word "back" is used in first sentence i.e. noun, verb, or adverb.

[Alan]

Hi,

No these are 'active' in form. 'Back' here is used as an adverb.
