Past Continuous

I love to say that grammar is easy. 
I hope this article on Past Continuous will prove it to you.

As usual I will cover formation, usage with examples.

Formation

As you can see, we use the familiar verb 'to be' (its past forms) and verb with ending -ing.

Key information on Pest Continuous formation:

• remember about sentence structure: subject + predicate (e.g. I was reading);
• past forms of the verb 'to be' - was and were.
  It carries out  only grammatical meaning. 
• We use verbs with -ing ending: reading, playing.It conveys the meaning of the process.
  It shows what was happening.

Usage

Past Continuous has four possible usages:

• action in the middle of happening at a stated past time:

This time last week I was traveling across Africa.

•  two or more simultaneous past actions of certain duration:

I was washing up while he was cooking the dinner.

• background description to events in  story:

She was walking alone the river...

• past action in progress interrupted by another past action:

I was reading a newspaper when the telephone rang.
