1) I didnt phone you, because it was very late.
2)I turned up the radio in the lounge so that I could hear it in the kitchen.
3)The restaurant was full, so we went to the bar next door.
4)I stayed at home as I was expecting a phone call.
5)It’s a very large city, so you have to use public transport a lot.
6)My mother didnt have to take me to the riding school every week, since i learnt to drive.
Фух,удачи :)
