Form of past continuous
The past continuous is used to express and action or a state that was happening at the time of the speaking. The action was not finished.
Past continuous: positive and negative
Past continuous: question
Past continuous: be careful!
1. All continuous verbs forms are composed of the auxiliary verb 'be' plus the gerund (-ing ) of the main verb.
2. We use the continuous only for verbs which describe actions.
3. Note that for questions is not necessary to use 'do' because there is already an auxiliary verb 'be'.
