12．We have always been interested in the moon.2，000years ago，people already knew it moves 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 the earth．This was because they believed the moon had once been a planet that had been caught in the earth's gravity millions of years earlier．
In 1969，moon 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 the earth．They believe very early in its history，maybe 4billion years ago，something about the size of Mars hit the 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．

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 61．D，细节理解题．根据We have always been interested in the moon.2，000years ago，people already knew it moves around the earth 可知在2，000年前，人们已经知道月亮绕着地球转，故选D．
62．C，细节理解题．根据believed the moon had once been a planet that had been caught in the earth's gravity millions of years earlier．可知他们认为月亮曾经是一颗行星，在数百万年前受到地球引力作用．因此第三项符合题意，故选C．
63．B，细节理解题．根据After years of study，most scientists now think that the moon was once part of the earth．可知经过多年的研究，大多数科学家现在认为月球曾经是地球的一部分，故选B．
64．B，理解推断题．根据文章内容In the future，even though our ideas about the moon may change again，we will still be interested in it．可知本文作者告诉我们的对月亮的认识是如何随时间而改变的，故选B．
65．C．细节理解题．根据the future，even thought our ideas about the moon may change again，we will still be interestedin it．可知在未来，我们对月球的认识可能再次改变，但是，我们仍然对它感兴趣．因此明确一点，新的信息带来新的想法，故选C．
点评 做题时要在理解好文意的基础上，与题目有机的结合，从文章中找到相关细节性的句子与选项细细比对，进行选择或推理判断，选出符合文章内容的正确选项．做题注意灵活，有时可采用排除法或直选法确定出最终答案．
