explanation: the "soundtrack" plays the role of "setting off the atmosphere" in the "movie". the function of the "preface" is to express the ideological content and characteristics of the "writing", and the function of the "preface" is not to "acknowledge". "display" is the role of "screen", "display" is not the role of "television". the role of "props" in "drama" is decoration, the role of "props" in "drama" is not "hint". the "mast" plays the role of "bracing" in the "sailing boat".
