PRESENT PERFECT SIMPLE TENSE

9TH GRADES

May 2, 2023 By Teacher Danitza 2

How do we use it?

• We use the Present Perfect Simple to talk about experiences. It is important if we have done it in our lives or not. It is not important when we did it.

Examples: I have been abroad two times.Anna has never broken a leg.


PRESENT PERFECT SIMPLE TENSE


• We use the Present Perfect Simple to talk about an action which started in the past and continuous up to now.

Examples:

I have been a teacher for more than ten years.

We haven't seen Janine since Friday.


• We also use the Present Perfect Simple to talk about a past action that has the result in the present.

ExamplesI have lost my wallet. (I don't have it now)

Jimmy has gone to South America.(He isn't here now)


What about its formulas?

In the affirmative sentence we'll use the auxiliaries have and has according to the personal pronouns they use with.For example:

I / We / You / They + have + past participle verb + complement

I have eaten octupus.

He / She / It + has + past participle verb + complementShe has heard about you.


In the negative sentence we are going to use the negative auxiliaries haven't and hasn't.

For example:I / We / You / They + haven't + past participle verb + compl.

We haven't done our jobs.He / She / It + hasn't + past participle verb+ compl.

It hasn't eaten its bone.


Finally, in the interrogative sentences the auxiliaries go before the person or subject.

For example:(Wh)+ Have + person + past participle verb+ C + ?

Has Have you learnt English? Yes, I have. No, I haven't.What has she done? She has done her homework. (This answer is an affirmative sentence)

The Present Perfect Simple vs

The Past Simple


We use the Past Simple when we talk about a completed action in the past, or when we know the time period is complete.

I wrote two letters yesterday.

The Present Perfect Simple is used for actions in the past when the period of time is not finished.

I've written two letters this morning.


Ago and Last are often used in the Past Simple. Ago goes at the end of the sentence and Last before the main verb.

I last went to Brazil two years ago.

The Present Perfect Simple use: Already, Yet, Since, For, Just, Ever, So far, and so on.

She's just finished her homework.
