Past Continues Tense 

 The past continuous tense, also known as the past progressive tense, is used to describe an ongoing action that was happening in the past at a specific time or over a period of time. It emphasizes the duration or continuity of the action.

The formula for the past continuous tense is:

Subject + was/were + verb-ing

Here's a breakdown of the formula:

For singular subjects (I, he, she, it), we use "was" + verb-ing.

For plural subjects (we, you, they), we use "were" + verb-ing.

Now, let's look at some examples to illustrate the usage of the past continuous tense:

I was studying all night.

(This shows that the action of studying was ongoing in the past.)

She was cooking dinner when the guests arrived.

(The action of cooking was in progress when the guests came.)

They were playing football in the park.

(The action of playing football was happening at a specific time in the past.)

We were watching a movie while it was raining outside.

(The action of watching the movie and raining were happening simultaneously.)

He was working on a project throughout the day.

(The action of working on the project lasted for the entire day.)

Remember that the past continuous tense is used to describe actions that were ongoing in the past, and it is often used in combination with another past tense to provide a context or describe an interruption.
