write 3 PARAGRAPH using PRESENT PERFECT .

Answer 1

you don't know when it happened,you don't care when it happened, orthe time when it happened is a secret.

When talking about past events AND the time is unimportant, unknown, or a secret, the present perfect is a good tense to use.  What is the present perfect?  Here is an example:

I have visited 56 countries.

How is this grammar formed?  It is formed with the following words:

Ihave visited56 countries.subject+have or has+past participle

The past participle and the simple past are sometimes the same.  Sometimes they are different.  For the word visited, the simple past and the past participle are the same.  If the simple past and past participle are different, they are usually irregular verbs.  For a list of irregular verbs, click here.

 simple pastpresent perfectexampleI visited 56 countries.I have visited 56 countries.feeling and meaningThe feeling and meaning here is that the person visited 56 countries, but his/her traveling is finished.The feeling and meaning here is that the person visited 56 countries, and so far the traveling is finished; however, his/her traveling may continue in the future (but it may not continue).  specific time?The person may put a specific time in this sentence.  It is optional. The person may NOT add a specific time.CORRECT:I visited 56 countries last year.INCORRECTI have visited 56 countries last year.

The present perfect can give a starting time or an amount of time only if you use the words since and for.  When using these words, the sentence usually means that the action is continuing.   If you do not use since or for, the sentence means the action is finished, and it may or may not continue in the future.  Take a look at these examples:

I have smoked.I have smoked for 12 years.NOT SURE it continuesSURE it continuesMeaning:  The person smoked in the past (we don't know when), and he/she may still smoke, but we do not know.Meaning: The person started to smoke 12 years ago, and he/she still smokes.
