Past simple

Remember that the structure of a sentence in the past is the same as in the present. The only difference is that the verb to be is in the past instead of in the present.

          Present: She is a very happy girl
          Past: She was a very happy girl
          
          Present: They aren't in Newcastle
          Past: They weren't in Newcastle
          
          Present: Are you interested in Maths?
          Past: Were you interested in Maths?
