a metal screen protected the observers.
a screen of trees afforded privacy.
a star of stage and screen.
block out the strong sunlight.
screen a film.
screen the blood for the HIV virus.
screen the job applicants.
screen the suitcases.
screen these samples.
the brush provided a covert for game.
the simplest concealment is to match perfectly the color of the background.
they had just moved in and had not put up blinds yet.
they put screens in the windows for protection against insects.
under cover of darkness.
