I thought of the people who had once used them.

In southern China, every bit of land is used not once but three times.

The school site was once used as a military base.

It will not last long and the drug can only be used once.

They've left out women; the word is not used once during the 10-minute film.

The 122,000-square-foot building was once used to store county court records.

Once used as a prison, since 2008 it is home to a museum.

They can only be used once and everyone carries them.

Each character has a special ability or "power" which can be used once during a game.

Its ground floor, built of stone, was once used as a market hall.
