人教版高一英语必修三Unit 4课文翻译Unit 4 Astronomy:the science of the stars —Reading—HOW LIFE BEGAN ON THE EARTH地球上生命的起源No one knows exactly how the earth began, as it happened so long ago. However, according to a widely accepted theory, the universe began with a "Big Bang" that threw matter in all directions. After that, atoms began to form and combine to create stars and other bodies.没有人确切知道地球是怎样开始形成的，因为在很早很早以前它就形成了。
然而，一种普通为人们所接受的理论是：宇宙起源于一次大爆炸，这次大爆炸将物质投射到四面八方。
然后，原子开始形成并结合成恒星和其他天体。
For several billion years after the "Big Bang", the earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into a solid globe. The earth became so violent that it was not clear whether the shape would last or not. It exploded loudly with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were to make the earth's atmosphere. What is even more important is that as the earth cooled down, water began to appear on its surface.大爆炸后好几十亿年过去了，但地球还只是一团尘埃。

Unit 4 Astronomy：the science of the stars
话题导入
Each new tool added to the files of astronomy; it helped man reach out into space. Until there were telescopes(望远镜), man knew little about the moon. They did not know that the planet called Saturn(土星)has rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets.
