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.

When I was ten, my mother worked all day so I had to take care of my younger brother. At that time my little brother was about four years old and he missed mum all the time.

One day, after I had given him his dinner, he started crying for mum. He was so young and really needed mum. So I dressed him, put on his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour later, I found that he had lost a shoe while sleeping. I took him off my back and put him down. I knew we needed to find that shoe, for our mother couldn’t afford new shoes. We had to go back to find it, so I told my brother to wait right there. A man heard it and stopped me just before I walked off. He asked me, “You are leaving your brother here to find the shoe? What would you do if he is not here when you return?” I did not know how to answer that question. He continued, “It’s OK if you can’t find the shoe, but it is not OK to lose your brother.” Then he sent us to mum’s workplace by taxi.

My whole life I have depended on the kindness of many strangers, I feel regretful that I cannot find them and say thank you. I do not even remember what the man’s face looked like, but he taught me a lesson—people are more important than things.

1. Why did the younger brother cry for his mother?
