Question

We have always been interested in the moon.2000 years 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 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 Earth.They believe very early in its history, maybe 4 million 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.

【解析】

试题分析：本文讲述了人类对月球的了解历程。2000多年前，人们通过仔细观察知道月球绕着地球转，而且一年中不同时间月球在空中的位置不一样；当科学家们用天文望远镜研究月球时，人们知道月球是由岩石构成的，推测月球是一颗被地球引力吸引住的星球；1969年，月岩被带回地球后， 我们知道月球的构成和地球一样，只是没有水，由此推测月球曾是地球的一部分，因为被星球撞击成碎片，后面慢慢聚在一起而形成了月球。在未来，我们对月球的想法可能还会改变，我们仍然会对它感兴趣。

1.C 常识题。题意：现在我们确信什么？A.Moon rocks are quite different from those on Earth.月岩和地球上的岩石完全不同；B.Moon was once a part of Earth.月球曾是地球的一部分；C.Moon moves around Earth and it’s the only satellite of Earth.月球绕着地球转，而且是地球唯一的卫星；D.Moon was once a planet caught in Earth’s gravity.月球痼是被地球引力吸引的星球。根据常识，我们知道月球绕着地球转，而且它是地球唯一的卫星故选C。

2.D 细节理解题。题意：在1969年有一件大事，是什么？A.humans Found no water in Moon rocks人类在月岩里发现在没有水；B.scientists made out a modern spaceship科学家制出了现代的飞船；C.scientists invented an advanced telescope科学家发明了高级的望远镜；D.humans left their footprints on Moon 人类在月球上留下了脚印。由文中的： In 1969 moon rocks were finally brought to the earth and studied可知人类在1969年从月球取回了月岩。说明人类到了月球。故选D。

3.3】B 主旨大意题。题意：短文作者想要告诉我们什么？A.Why people are interested in the moon.为什么人们对月球感兴趣？ B.How ideas about the moon have changed over time.关于月球的想法是怎样改变的；C.Where the moon came from in the past.月球过去是从哪儿来的； D.That people have finally learned the truth about the moon.人们终于了解到了月球的实情。短文主要讲述的是人类对月球的了解史。故选B。

4.4】C细节理解题。题意：在1969年以前，许多科学家怎样认为月球的？A.part of the earth billions of years earlier数十亿年前是地球的一部分；B.older than the earth比地球早； C.a planet caught by the earth's gravity被地球引力吸引的一颗星球；D.made of the same things as the earth由和地球一样的物质构成。由第二段里的： 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.可知当时人们认为月球是被地球引力吸引的一颗星球。故选C

5.5】C 推理判断题。题意：从本文中我们可以了解到什么？A.scientists in the past were not clever过去的科学家不聪明；B.the earth was once part of the moon地球曾是月球的一部分；C.new information brings new ideas新的信息带来新的想法；D.we now know everything about the moon现在我们了解了月球的一切。根据本文内容，人们一步一步地对月球的深入了解，改变着人们对月球的一些想法。说明新的信息可以带来人们对事物的新的认识，新的想法。故选C。
