Understanding Completed Past Actions

The Past Simple is used to talk about finished actions that happened at a specific time in the past. Think of it like taking a snapshot of a moment that’s already happened.

Time Expressions

We often use specific time expressions like: yesterday, last week, two days ago, in 2020, at 6pm

Examples

I watched TV last night.A single, completed action with a clear time (last night)
She visited her grandmother on Sunday.The visit happened and finished on a specific day
They moved to London in 2021.A completed action with a specific year mentioned
