1) My brother and I skipped school to go to the movies. So next weekend we'll have to stay at home.

2) A terrible sound came from the basement in our old house. I decided to find out who was making this sound and went down there with a flashlight.

3) Yesterday I was at the dentist and while I was waiting for my turn I looked through the magazines on the table.

4) During my vacation, I have accumulated a lot of work, so I will have to work till the night for a whole week.

5) I think we should go on with the meeting and stop wasting time, because otherwise we run the risk of failing to meet the deadline.
