1. When I went to the airport I saw / met my friend whom I knew from primary school.
2. He was punished because they committed a very serious offense.
3 When we returned home we noticed that someone smashed the window, broke into and robbed us.
4. I had to buy a new car because the old broke down.
5. When John returned home children went to sleep, so he went to the room and kissed them good night.
Mam nadzieję, że pomogłem :)
