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 我們一直對月亮感興趣．在2，000年前，人們已經知道月亮繞著地球轉．1969年，人類從月亮上帶回了巖石．令他們驚訝的是，科學家們發現除了水，地球和月亮都是由同樣的物質構成的．這個新的信息提供了新的想法．
解答 61．D，細節理解題．根據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，人們已經知道月亮繞著地球轉，故選D．
62．C，細節理解題．根據believed the moon had once been a planet that had been caught in the earth's gravity millions of years earlier．可知他們認為月亮曾經是一顆行星，在數百萬年前受到地球引力作用．因此第三項符合題意，故選C．
63．B，細節理解題．根據After years of study，most scientists now think that the moon was once part of the earth．可知經過多年的研究，大多數科學家現在認為月球曾經是地球的一部分，故選B．
64．B，理解推斷題．根據文章內容In the future，even though our ideas about the moon may change again，we will still be interested in it．可知本文作者告訴我們的對月亮的認識是如何隨時間而改變的，故選B．
65．C．細節理解題．根據the future，even thought our ideas about the moon may change again，we will still be interestedin it．可知在未來，我們對月球的認識可能再次改變，但是，我們仍然對它感興趣．因此明確一點，新的信息帶來新的想法，故選C．
點評 做題時要在理解好文意的基礎上，與題目有機的結合，從文章中找到相關細節性的句子與選項細細比對，進行選擇或推理判斷，選出符合文章內容的正確選項．做題注意靈活，有時可采用排除法或直選法確定出最終答案．
