Past form or be -ing?
Past Simple vs Present Progressive

When do people use the past form and when do we use be -ing? Let’s look at some sentences with the past form (past simple) and be -ing (present progressive/present continuous)  to better understand the meanings -ed and be -ing add and why speakers choose to use them.

Or start with our practice exercises.

Why do we use them?

We add the past form (-ed) to show we aren’t referring to the present-future. Things that do not happen in the present-future often finished in the past.

We add be -ing to show something is not finished.

Compare:

We use the past form for finished actions. They happened in the past.

We use am/are/is + -ing form for actions that are not finished. They are happening in the present-future.
