Past Continuous

Afirmativas       As frases afirmativas no past contínuous são compostas do sujeito mais o verbo TO BE no passado, seguido do gerúndio do verbo principal. Veja alguns exemplos:

* They were reading (eles estavam lendo)
* I was learning (eu estava aprendendo)

* Lembrete: tabela do verbo TO BE no passado:
I – Was / You – Were / He – Was / She – Was / It – Was
We – Were /  You – Were / They – Were

Interrogações
      As frases interrogativas do past continuous apenas trocam o sujeito principal com o gerúndio do verbo, como no Presente Contínuo:
* Were they reading? (Eles estavam lendo?)
* Was I learning? (Eu estava aprendendo?)

Negações
      Para converter uma frase afirmativa do past continuous para negativa, basta apenas adicionar o NOT depois do verbo TO BE:
* They were not (weren’t) reading (eles não estavam lendo)
* I was not (wasn’t) learning (eu não estava aprendendo)

E é isso gente , espero que gostem !! ;) Abraços ..
