看不看歌词, 语法也不会是飞越
有fly over, 从来没见过什么 fly on
另外 fly on the wall 也是一种技法习语, 解释如下:
Fly on the wall is a style of documentary-making used in film and television. The name derived from the idea that events are seen candidly, as a fly on a wall might see them. In the purest form of fly-on-the-wall documentary-making, the camera crew works as unobtrusively as possible; however, it is also common for participants to be interviewed, often by an off-camera voice.
