38. Key points to remember 1 The past simple describes completed events in the past, such as the main events in a narrative. It can also describe habits and routines in the past. 2 The past continuous is used for: a) background description. b) actions in progress, often contrasted with a sudden event. The past continuous cannot be used to describe past routines and habits. 3 Participle clauses can introduce a clause giving the main event. The subjects of both clauses must be the same.

39. 4 The past perfect describes a past event which took place before another past event. If before or after is used, the past perfect is optional. The past perfect is not used for an event that happened a long time ago in the past. 5 Used to only refers to past time, and has no present form. 6 Would can be used to describe habitual actions in the past, usually in writing. It does not make such a strong contrast with the present as used to. Compare: Jim would always make his mother a cup of tea after lunch. Jim used to drink tea, but now he prefers coffee. Would cannot be used to describe states. Sally used to be a dancer.
