Question

【題目】We have always been interested in the moon. 2, 000 years 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 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 though our ideas about the moon may change again, we will still be interested in it.

【2】B

【3】C

【解析】

試題分析：這篇短文告訴大家：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(fā)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。

【1】細節(jié)理解題。問題：在1969年之前，大多數科學家認為月亮是怎么樣的？聯系原文：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

【2】細節(jié)理解題。問題：在數年的研究之后，大多數的科學家現在又是怎樣解釋月亮的？聯系原文：maybe 4 billion years ago, something about the size of Mars hit the earth.句意：可能在40億年前，一些火星的大小的物體撞擊了地球。故選B

【3】細節(jié)理解題。問題：通過這篇短文，我們能了解到什么？聯系原文的中心句：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
