Question

It is sometimes reported that strange flying objects have been seen high up in the sky. People call these strange objects Unidentified(不明的)Flying Objects(UFOs). These UFOs caused a lot of interest. Some of the reports about them are difficult to believe.Some have been explained in scientific ways. Others have never been explained.
Here is an account of UFOs from a report.
Dennis Bardens,who wrote an article,tells us that he once saw a UFO himself.He was having dinner one night with a friend near Tripoli(的黎波里),Libya(利比亚),and after dinner the two men walked across a yard to his room to look at some papers.Bardens noticed that the moon looked strange that night.
“It wasn't the moon,”was the reply.
They watched the light and saw that it was moving.It seemed to be an object rather like a big plate.In some ways it looked like smoke with a light on it,but it wasn't smoke because it didn't change its shape.It was moving in a regular way.That is to say,it didn't go suddenly faster or more slowly,and it didn't go higher or lower.So the two men decided that there must be men in it.
When it came nearer to Libya,Bardens said that he felt eyes looking at him.He was being watched in the darkness.
When it was nearer,they noticed that the bottom parts were brighter than the top.The bottom was yellow and the top was red.Then the object suddenly turned away and left Libya,moving very fast.
On a later day Bardens talked to other people about it,and he found some who had seen it.They all described(描述)it in the same way.Could they all the mistaken?

Answer 1

BADB
1.UFO是一种奇怪的飞行物。从文章前两句可找到答案。从“some of the reports about them are difficult to believe.”可知：有关UFO的一些报道使人难以相信，而不是UFO难以置信，因此C不对。D项正确表达应为“The UFOs are very interesting.”A项说“The UFOs are flying high up in the sky.”不合事实。
2.从“……and after dinner the two men walked across a yard to his room to look at some papers.Bardens noticed that the moon looked strange that night.”可以推断A为看到UFO的时间。B项说“他们在看着灯光的同时，看到了UFO”，这是不对的。当他们看到UFO时，Bardens误以为那是月亮，其实那个奇怪的月亮“就是UFO”，因此C也不对。D项内容与“……and after dinner……”中的时间不相符。
3. UFO看起来好像个大碟子（盘子），又像带着一盏灯的烟，但又不是烟。由此，可确定D正确。
4.当UFO接近利比亚时，突然掉头离开利比亚。A项说“UFO一下子消失了”不对。从“…Bardens said that he felt eyes looking at him.He was being watched in the darkness.”可判断出C项不正确（在黑暗中被注视的是Bardens而非UFO）。
