b. When do we use the past perfect? Can you think of any rules?
We use the past perfect to describe an action before a stated time in the past.

We use the past perfect to describe an action that happened before another action in the past.
Example:

Example:

Last Tuesday, I was annoyed because I had missed my school bus.
