Present conditions tense

Good morning grade 6
Today we will study the use of present perfect tense

THE FORM : Subject + has/have + Past participle ( second form of the verb )

We use the present perfect tense to
1- Describe an experience
EX : I have travelled the world
      He has never been to the space

2- Describe a change over a period of time
EX : house prices have increased a lot
      The country has changed dramatically

3- Describe accomplishments ( achievements )
EX: Doctors have discovered cures for many diseases
     Mobiles made it possible to learn online

4- describe an action started in the past
EX:  The match has started from 30 minutes
      They have watching television all the night
   
Look on the following  examples and focus on how the use of ( has / have ): changed when we change the pronoun

1- I have played football all the day
2- They have played football all the day
3- we have played football all the day
4- He has played football all the day
5- She has played football all the day

you will find that
HAS comes after ( he / she / it )
Have comes after ( we / they / you / I )
