1.She used to meet her friends every day.
2.They used to drink some milk every day.
3.He used to swim in the river every day.
4.She used to take him to school every day.
5.He used to cut himself every morning.
因为有every day,所以用used to 来表示过去常常
我认为这样比单纯的过去时好多了
而且She goes to town every day.的过去时应该是She went to town.
