Ex. 4. example՝ Yesterday my family and I visited my grandparents.
My mum helped my grandma with the housework.
My dad cleaned the windows.
My brother and I watched cartoons on TV.
Later we played outside in the garden.
We climbed up the tree to get to the treehouse.
We stayed there all afternoon.
Then our mum called us because it was time to go.
Our grandparents kissed us goodbye and we returned home.
