Grammar: Past tense practice

When we want to talk about actions which started and finished in the past, we use a past simple tense. Verbs can be regular or irregular.

We make negative sentences using didn't + base form
       I didn't write        He didn't play tennis

We make questions using did + subject + base form
       What did you write?      Did he play tennis?

We make positive sentences using the past simple/second form. The past simple form can be regular or irregular. We make the regular form using base form + ed
        play ----> played           enjoy ----> enjoyed

However, many verbs are irregular. They are often the most common verbs. The past simple form is very different from the base form go ----> went     write ----> wrote     do ----> did      have ----> had. You need to learn these irregular verbs.
