The origin( 起源 ) of the names: In the United States, the first flying saucers were reported on June 4, 1947, by a private plane pilot( 飞行员 ).He saw nine objects traveling in the sky. Each was disk shaped and very bright. Because their movements were compared to ( 比做 )those of a “saucer ( 碟子 )skimming across the water”, newspaper reporters called them “flying saucers”.
Some weeks after the first reported sighting （目击）, the United States Air Force was given the job of investigating （调查） all the reports of flying saucers. Because of the confusing （令人费解的） variety of shapes, sizes, and colors reported, the Air Force adopted （采用） the term “Unidentified Flying Objects” (UFO) to describe them.
