Теория:

Study some information about positive sentences in Past Continuous.
 
Для образования Past Continuous необходимо использовать вспомогательный глагол to be (варианты was, were) и основной глагол, к которому мы добавляем окончание -ing.
  
Для построения утвердительного предложения нужно использовать следующий порядок слов:
subject \(+\) to be (was/were) \(+\) Ving \(+\) other parts of the sentence.
Was используем для первого и третьего лица единственного числа (I, he, she, it).
 
Were — в остальных случаях.
 
 
              I                  
                                                                was studying
 
       
            you
 
were studying
 
he, she, it
 
was studying
 
we

You

Examples:
