Past perfect

I turned on the TV

When our friends arrived

I couldn’t get into my flat because

I took the sweater back because

At work I suddenly remembered that

Jack didn’t come with us.

When the film started

Jenny was nervous because

I’d forgotten my keys.

we hadn’t finished cooking the dinner.

he had bought me the wrong size.

I hadn’t turned off the cooker.

I realized that I’d seen it before.

it was the first time she had flown.

to see what had happened.

He had made other plans.
