Past perfect

By the time we arrived at the theater,
She had finished her homework
They had prepared everything
I didn’t go to the concert
By the time we got there,
They had just left
She didn’t feel well because
He had never seen a desert
After they had packed,
We had finished our project
the movie had already started.
before her friends came over.
before the guests arrived.
because I had lost my ticket.
he had already left the restaurant.
when it began to rain.
she had eaten too much.
before he visited Egypt.
they called a taxi to the airport.
before the teacher checked it.
