1. Lorna's party was very dull. Only about half a dozen people turned up.
2. It wasn't a very good concert. Lots of people left before the end.
3. There are quite a few new students in the class this week.
4. There were hardly any tickets left for this concert, so I was lucky to get one.
5. There were loads of people in town this morning. I think there was some kind of demonstration.
6. I've had dozen of replies to the advert I put in the paper.
