I almost fell over, the door came open so fast.

From beyond the door came the sounds of a party in progress.

The door was already coming up when he struck the ground.

And then there was a silence in the room as the door came open.

The door to the private office opened and in came a young man.

He heard the door open behind him as Wells came into the room.

At the same moment, the door to the colonel's office came open.

The driver's door of the other car came open and a man got out.

The door came open under his hand but he did not enter.

In less than a minute, the door slowly came open.
