⼈教版⾼⼀英语必修三Unit4课⽂翻译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。
