Past Simple, Past Continuous, and Past Perfect Exercises

To clearly and accurately talk about things that happened in the past, you need to know the difference between past simple, past continuous, and past perfect. These three tenses help us talk about what happened, what was happening, and what had already happened before something else.

This guide will show you how these tenses are set up, what they are used for, and how they are different from each other with clear examples that B1 learners can understand.

• He was tired because he had not slept well.

With words like before, after, already, just, and by the time

The Three Tenses: Key Differences

Simple Past vs. Past Continuous

Past simple = finished action
Past continuous = action in progress

Example:

• I watched TV. (completed action)
• I was watching TV. (action in progress)

Example with interruption:

• I was watching TV when she called.

Past Simple vs Past Perfect

Past simple = action in the past
Past perfect = action before another past action

Example:

• When I arrived, she left. (order is unclear)

Better:

• When I arrived, she had left. (she left before I arrived)

Past Continuous vs Past Perfect

Past continuous = action in progress
Past perfect = action completed before another past action

Example:

• I was studying when he arrived.
• I had studied before he arrived.

Timeline Example

Let’s look at this example:

• I had finished dinner.
• I was watching TV.
• My friend called me.

Correct sentence:
