This tense gives difficulty because students look upon it as a past rather than a present tense.It's a present tense describes events which happened in the past but are closely connected with the present.

- I have been a teacher for 9 years " still teaching from past till this moment "

 - I was a teacher for 9 years " I'm not teaching now".

- He Has broken his leg ." It's still broken now"

-He broke his leg ." In the past but not connected to the present ".

If we bear this important point in mind we will avoid many tense mistakes.

 Usage :

We use the present perfect tense to talk about:

1-Past events and activities with results in the present

   - Her last book has been a great success.

   -I have ( I've ) lost my keys ." I can't open the door ".

2-Things that started in the past and continue up till now

   - Haven't you finished your homework yet?

   - I have worked here for 3 years .

3-An action in the past when we don't know or not interested in exactly when it happened.

   -I have always dreamt about going to Spain.

   -She has written the report.

 

   Form:

 We form the present perfect tense with:

A present form of have " has with the third person singular" + the third form of the verb .

   - He has had this cough for a long time.

   -They haven't seen each other for ten years "  Negative "

   -Has he decided what to do?  " Question"

 Time adverbials :

We use the following time adverbials with this tense

 - Before- ever - never-seldom-just -sometimes -often ...

 - We have never heard such a horrible news.

  -I have often tried to cook ,always with disastrous results . 

-Already :

Yet:" at the end of the sentence  in negative and question only"

-  We haven't seen this film yet.

- I haven't repaired my car yet.

 - For / Since:

 For :" tells us  a period of time which the activity has taken ... "

 since: " tells us about a point in time when the activity began "

 - I have lived in this town for 2 years .

  • Hello Lolo-yaya,

    You have understood the lesson well.  There's just one point I'd like to make things clear here.  You are in the habit of putting independent sentences in one sentence........like your nos. 2,3 and 4.  They are not incorrect but we usually separate independent clauses in a sentence.  Or we may add connectors (consequently, furthermore, etc.) or conjunctions (for, and, but, or, etc.) to make the sentence beautiful to read.

    As our rule here, we aim to seek perfection in studying our English lessons that a slight error in your exercises will render your answers incorrect.

    2- I have just come back home, it's so hot out side. outside.

    3- He has already finished his working work, he is coming home now.

    4- My kids haven't slept yet, they are lying on thier their beds.

    Be careful next time.

  • Dear Cold Moon.........except for no. 3 in Exercises A, the rest are correct.  Remember that we are on THE PRESENT PERFECT TENSE.  There are only two words that you should remember when using this tense........HAVE and HAS.

    3- University did not start yet.  (University has not started yet.)
