Step-by-step explanation:
The Past Continuous tense has the following structure:
subject + past form of "be" + main verb with -ing
The past form of the verb "be" is either "was" (I, he, she, and it) or "were" (you, we, and they).
The Past Continuous is used to talk about actions that happened for a period of time in the past, that is, actions that started and lasted for a while. The examples below help illustrate that:
- I was cooking pasta when my mother arrived.
- Nina wasn't answering her phone, so I called her sister.
- Were you watching TV instead of studying?
