To talk about two simultaneous short actions we use simple tenses. To talk about a longer background action which was going on when something else happened, we use the past continuous tense. We usually use the past simple tense to refer to the shorter action that interrupted the longer background action.
Complete the following sentences using an appropriate past simple or past continuous tense.
