USED TO

 

Mary and Sophia stopped playing with their dolls three  years ago.

They do not play with their dolls any more.

They used to play every day.

You can use USED TO to talk about past habits and situations.

Something used to happen: something happened regularly in the past but not longer happens.

                      I used to play tennis a lot but I do not play very often now.

I used to do something is past. There is no present form. You cannot say "I use to do" 

You also use USED TO ... for something that was true but it is not true any more.
