Question

We have always been interested in the moon.2000 years ago, people already knew that the moon 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 werefinally 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 4 billion 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 thought our ideas about the moon may change again, we will still be interested in it.

试题分析：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。
小题1:细节理解题。问题：在两千年前，人们已经知道了什么？分析原文：We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth.句意：在两千年前，我们就已经对月亮感兴趣了，人们已经知道月亮绕着太阳转。故选D
小题2:细节理解题。问题：在1969年之前，大多数科学家认为月亮是怎么样的？联系原文：they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.句意：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
小题3:细节理解题。问题：在数年的研究之后，大多数的科学家现在又是怎样解释月亮的？联系原文：maybe 4 billion years ago, something about the size of Mars hit the earth.句意：可能在40亿年前，一些火星的大小的物体撞击了地球。故选B
小题4:细节理解题。问题：通过这篇短文，我们能了解到什么？联系原文的中心句：In the future, even thought our ideas about the moon may change again, we will still be interested in it.句意：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
