12.We have always been interested in the moon.2000years ago people already knew it moved around the earth and where it would be in the sky at different times of the year.At that time,everything about the moon was learned by watching it carefully in the sky.When scientists could use telescopes to study the moon more closely,their ideas began to change.They could see the moon was made of rocks.Most scientists thought moon rocks would be different from those on Earth.This was because they believed the moon had once been a planet that had been caught in the earth's gravity (引力) millions of years earlier.
In 1969moon rocks were finally brought to the earth and studied.Much to their surprise,scientists found that,except for water,the moon and the earth were made of the same things.Once again new ideas were needed for this new information.
After years of study,most scientists now think that the moon was once part of Earth.They believe very early in its history,maybe 4million years ago,something about the size of Mars hit Earth.This sent billions of rocks into space around our planet.These rocks slowly joined together and after many years became the moon.
In the future,even though our ideas about the moon may change again,we will still be interested in it.

C.a planet caught by the earth's gravity D.made of the same things as the earth
55.From this passage we can learn thatC.

分析 我们一直对月亮感兴趣.在2,000年前,人们已经知道月亮绕着地球转.1969年,人类从月亮上带回了岩石.令他们惊讶的是,科学家们发现除了水,地球和月亮都是由同样的物质构成的.这个新的信息提供了新的想法.
解答 51-55:C D B C C
51.C.细节题.根据第一句We have always been interested in the moon.2000years ago people already knew it moved around the earth 可知月亮绕着地球转,结合常识可知月球是地球唯一一个自然卫星,故选C.
52.D.推理题,结合第三段In 1969moon rocks were finally brought to the earth and studied.Much to their surprise,scientists found that,except for water,the moon and the earth were made of the same things.Once again new ideas were needed for this new information.可知1969年人们在月球上留下了足迹,故选D.
53.B细节理解题.结合第一句We have always been interested in the moon.2000years ago people already knew it moved around the earth and where it would be in the sky at different times of the year可知作者是在告知人们关于月球的想法是怎样随着时间而改变的,所以选B.
54.C.细节理解题.根据第二段This was because they believed the moon had once been a planet that hadbeen caught in the earth's gravity millions of years earlier.可知这是因为他们认为数百万年前月亮曾经是被地球的引力吸引的一颗行星,所以选C.
55.C.细节理解题.根据最后In the future,even though our ideas about the moon may change again,wewill still be interested in it.可知新的信息会带来新的想法,所以选C.
