Объяснение:

В past continuous к смысловому глаголу ВСЕГДА добавляется окончание ing (do - doing)

Если в утвердительном предложении лицо, совершающее действие, в единственном числе, то используется was (wasn't/ was not в отрицательных предложениях)

Если в утвердительном предложении лицо во множественном числе, то используется were (weren't/ were not в отрицании)

В во предложениях порядок слов меняется (на первое место становится вс глагол was/were, потом идёт лицо, совершающее действие и смысловой глагол.
