B. Past Continuous is formed by using the adequate form of to be and the verb’s present participle: He was going to church. By inserting not before the main verb a negation is achieved. Example: He was not going to church. A question is formed by prefixing the adequate form of to be as in Was he going?.

Describing events that were just about to occur when a new event happened. The already occurring event is presented in past continuous, the new one in simple past. Example: We were sitting in the garden when the thunderstorm started. Use is similar to other languages' imperfect tense.
