     Sometimes people say that they see strange flying objects (物体) high up in the sky. People call these

strange objects “Unidentified Flying Objects (UFOs)".

     Dennis Bardens wrote an article. In it, he told us that he once saw a UFO himself. He had dinner one

night with a friend near Tripoli, Libya. After dinner Dennis with his friend walked across a yard (院子) to

his room.He noticed that the"moon"looked strange that night. But it wasn’t the moon. He saw the object’s

light was moving. It seemed to be an object like a big plate. In some ways it looked like smoke with light

on it.But it wasn’t smoke because it didn’t change its shape (形状).When the object was nearer,he noticed that its bottom (底部的) part was brighter than the top. The bottom part was yellow and the top was red. Then the object suddenly turned away and left, moving very fast.

     On a later day, Dennis talked to other people about it, and he found some people also saw it. They all described (描述) it in the same way.
