Question

【题目】Astronomy (天文学) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens(天堂). But the six planets that he could see with his eyes alone limited man.

The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.

Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes(望远镜), man did not know much about the moon. He did not know that the planet called Saturn(土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.

Before the spectroscopes (分光镜), man didn’t know what kind of gas was in the sun or other stars, without radio telescopes(射电望远镜), we did not know that radio noise came from far in space.

Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.

Answer 1

【答案】

【1】B

【2】D

【3】A

【4】C

【解析】天文学的发展史就是一部观测仪器不断进步的历史，从古希腊到现代，随着观测仪器越来越先进，人们对太空的了解也越来越多。

【1】 B细节理解题。根据第一段第二句Thousands of years ago man looked at the stars and wondered about heavens (天堂).可知，几千年前人们用肉眼观察星星。

【2】D细节理解题。根据第二段倒数第二句They watched the stars move as the seasons changed.可知，古希腊人能观察到星星随着季节移动。

【3】A细节理解题。根据第三段第二句Until there were telescopes(望远镜), man did not know much about the moon.可知，直到有了望远镜，人们才开始了解月球。

【4】C细节理解题。根据第三段最后一句Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.可知，直到1930年人们才发现了冥王星。
