When the small island came into view, the sun was already beginning to set.

But we were not done even then, as the sun began to set.

Not until the sun began to set did they find out.

Out over the sea the sun was beginning to set.

He could do nothing until the sun began to set.

Everyone worked hard until the sun began to go down.

In three hours and a half, the local sun began to set.

The sun was already beginning to set in the night sky.

When the sun began to set she said that it was time to go.

The sun was beginning to lower itself in the sky, and there wasn't anyone on the street.
