Question

【題目】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.

A.Moon rocks are quite different from those on Earth.

B.Moon was once a part of Earth.

【2】In 1969 there is a big event, that is __________.

A.humans Found no water in Moon rocks

B.scientists made out a modern spaceship

C.scientists invented an advanced telescope

D.humans left their footprints on Moon

【3】What does the writer want to tell us in the passage?

A.Why people are interested in the moon.

B.How ideas about the moon have changed over time.

C.Where the moon came from in the past.

D.That people have finally learned the truth about the moon.

【4】Before 1969 most scientists thought the moon was ________.

A.part of the earth billions of years earlier

B.older than the earth

C.a planet caught by the earth's gravity

D.made of the same things as the earth

【5】From this passage we can learn that ________.

A.scientists in the past were not clever

B.the earth was once part of the moon

C.new information brings new ideas

試題分析：本文講述了人類對月球的了解歷程。2000多年前，人們通過仔細(xì)觀察知道月球繞著地球轉(zhuǎn)，而且一年中不同時(shí)間月球在空中的位置不一樣；當(dāng)科學(xué)家們用天文望遠(yuǎn)鏡研究月球時(shí)，人們知道月球是由巖石構(gòu)成的，推測月球是一顆被地球引力吸引住的星球；1969年，月巖被帶回地球后， 我們知道月球的構(gòu)成和地球一樣，只是沒有水，由此推測月球曾是地球的一部分，因?yàn)楸恍乔蜃矒舫伤槠�，后面慢慢聚在一起而形成了月球。在未來，我們對月球的想法可能還會改變，我們?nèi)匀粫�對它感興趣。

【1】C 常識題。題意：現(xiàn)在我們確信什么？A.Moon rocks are quite different from those on Earth.月巖和地球上的巖石完全不同；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.月球繞著地球轉(zhuǎn)，而且是地球唯一的衛(wèi)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。根據(jù)常識，我們知道月球繞著地球轉(zhuǎn)，而且它是地球唯一的衛(wèi)星故選C。

【2】D 細(xì)節(jié)理解題。題意：在1969年有一件大事，是什么？A.humans Found no water in Moon rocks人類在月巖里發(fā)現(xiàn)在沒有水；B.scientists made out a modern spaceship科學(xué)家制出了現(xiàn)代的飛船；C.scientists invented an advanced telescope科學(xué)家發(fā)明了高級的望遠(yuǎn)鏡；D.humans left their footprints on Moon 人類在月球上留下了腳印。由文中的： In 1969 moon rocks were finally brought to the earth and studied可知人類在1969年從月球取回了月巖。說明人類到了月球。故選D。

【3】B 主旨大意題。題意：短文作者想要告訴我們什么？A.Why people are interested in the moon.為什么人們對月球感興趣？ B.How ideas about the moon have changed over time.關(guān)于月球的想法是怎樣改變的；C.Where the moon came from in the past.月球過去是從哪兒來的； D.That people have finally learned the truth about the moon.人們終于了解到了月球的實(shí)情。短文主要講述的是人類對月球的了解史。故選B。

【4】C細(xì)節(jié)理解題。題意：在1969年以前，許多科學(xué)家怎樣認(rèn)為月球的？A.part of the earth billions of years earlier數(shù)十億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顆星球；D.made of the same things as the earth由和地球一樣的物質(zhì)構(gòu)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.可知當(dāng)時(shí)人們認(rèn)為月球是被地球引力吸引的一顆星球。故選C

【5】C 推理判斷題。題意：從本文中我們可以了解到什么？A.scientists in the past were not clever過去的科學(xué)家不聰明；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新的信息帶來新的想法；D.we now know everything about the moon現(xiàn)在我們了解了月球的一切。根據(jù)本文內(nèi)容，人們一步一步地對月球的深入了解，改變著人們對月球的一些想法。說明新的信息可以帶來人們對事物的新的認(rèn)識，新的想法。故選C。
