HOW LIFE BEGAN ON THE EARTH
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.
For several billion years after the "Big Bang",the earth was still just a cloud of st.What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the st 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 proce 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.
Water had also appeared on other planets like Mars but,unlike the earth,it had disappeared later.It was not immediately obvious that water was to be fundamental to the development of life.What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.This proced a chain reaction,which made it possible for life to develop.
Many millions of years later,the first extremely small plants began to appear on the surface of the water.They multiplied and filled the oceans and seas with oxygen,which encouraged the later development of early shellfish and all sorts of fish.Next,green plants began to grow on land.They were followed in time by land animals.Some were insects.Others,called amphibians,were able to live on land as well as in the water.Later when the plants grew into forests,reptiles appeared for the first time.They proced young entirely by laying eggs.After that,some huge animals,called dinosaurs,developed.They laid eggs too and existed on the earth for more than 140 million years.However,65 million years ago the age of the dinosaurs ended.Why they suddenly disappeared still remains a mystery.This disappearance made possible the rise of mammals on the earth.These animals were different from all life forms in the past,because they gave birth to young baby animals and proced milk to feed them.
Finally about 2.6 million years ago some small clever animals,now with hands and feet,appeared and spread all over the earth.Thus they have,in their turn,become the most important animals on the planet.But they are not looking after the earth very well.They are putting too much carbon dioxide into the atmosphere,which prevents heat from escaping from the earth into space.As a result of this,many scientists believe the earth may become too hot to live on.So whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.

For several billion years after the "Big Bang", the earth was still just a cloud of st. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when
the st 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 proce 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.
Water had also appeared on other planets like Mars but, unlike the earth, it had disappeared later. It was not immediately obvious that water was to be fundamental to the development of life. What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.

They multiplied and filled the oceans and seas with oxygen, which encouraged the later development of early shellfish and all sorts of fish. Next, green plants began to grow on land. They were followed in time by land animals. Some were insects. Others, called amphibians, were able to live on land as well as in the water. Later when the plants grew into forests, reptiles appeared for the first time. They proced young enerally by laying eggs. After that, some huge animals, called dinosaurs, developed. They laid eggs too and existed on the earth for more than 140 million years. However,
65 million years ago the age of the dinosaurs ended. Why they suddenly disappeared still remains a mystery. This disappearance made possible the rise of mammals on the earth.

Ⅳ 高一英语必修3 第四单元的课文全文翻译 题目为 How life began on the earth

没有人确切地知道地球是如何开始的，因为那是好久以前的事了。然而，根据广泛接受的理论，宇宙始于“大爆炸”，把物质在所有的方向。在那之后，原子开始形成并结合成恒星和其他天体。
对于“大爆炸”后数十亿年，地球还只是一团尘埃。什么是成为不确定直到4.5至3800000000年前，当尘埃落定成固体地球。地球变得如此暴力，也不清楚是否形状将持续。它的爆炸喷出了烈火和岩石。最终产生了碳，氮，水蒸气和其他的气体，从而形成了地球的大气层。更重要的是，当地球冷却下来，水开始出现在其表面。
水也出现在其他行星火星一样但不像地球，它已经消失了。这是不能立即明显，水是生命发展的基础。很多科学家相信，水的持续存在使得地球把有害气体溶解在海洋里。这产生了连锁反应，使生命发展成为可能。
数百万年后，第一个非常小的植物开始出现在水面。他们繁殖起来，使得海洋充满了氧气，这鼓舞了后来发展早期贝类和各种鱼类。其次，绿色植物开始成长的土地上。他们在之后的时间由陆地动物。有些昆虫。其他人，叫两栖动物，能够在陆地上生活以及在水。后来当植物长成的森林，爬行动物第一次出现。他们通常为卵生。之后，一些巨大的动物，所谓的恐龙，开发。它们产卵也和地球上存在超过140000000年。然而，65000000年前恐龙时代的结束。他们为什么突然消失，仍然是一个谜。这个消失的崛起成为可能的哺乳动物在地球上。这些动物不同于所有生命形式的过去，因为他们生了年轻的动物宝宝和生产的牛奶喂它们。
大约2600000年前的最后一些小聪明的动物，现在手和脚，似乎遍布地球。他们就这样，反过来，成为地球上最重要的动物。但他们不照顾地很好。他们把太多的二氧化碳释放到大气中，从而防止热量从地球逃逸到太空。因此，许多科学家相信地球会变得太热。所以生命是否会在未来的几百万年的地球上继续将取决于是否可以解决这个问题。

Ⅵ 人教版必修三 四单元reading2（A VISIT TO THE MOON)翻译 速求

月球之旅我的朋友李彦平是一位宇航员。上个月我有幸得到一个机会同他一起去太空旅行。我们乘宇宙飞船参观了月球。在启程以前，李彦平向我解释说，在我们的航行中会有三次引力的改变，而第一次的改变将是最强的。随后我们就起航了。随着火箭徐徐升空，我们慢慢逃离地球的引力。但这种引力太强了，把我们重重地向后推在座位上，以至于我们彼此间都不能说话了。随后，这个力量慢慢减小，我才能够同他讲话。我问道：“为什么太空船不会向后朝地球的方向落下去呢？在地球上的时候，如果我从书上掉下来，总会朝地上落下去的。”李彦平解释说：“现在我们离地球太远了，感觉不到地球的拉力，所以我们好像一点儿也感觉不到地球引力了。当我们更接近月球时，就会感到月球的引力在拉我们。但是，月球的引力不像地球的引力那么大。”我立刻感到很高兴，由于失重我在太空舱里飘来飘去，我望着（身后的）地球越来越小，而（前方的）月球越来越大。我们到达月球时，我就想立即进行探测。“来吧，”我说，“要是你讲得对，我的重量就会比地球小，而我就能够更自由地活动了。如果我在月球上呆的时间足够长的话，我甚至可能长得更高，我的体重肯定也会变得更轻！”我笑着从火箭的阶梯上爬下来。而当我试着向前迈步的时候，我发觉我被送出去很远，步子的跨度竟然是在地球上的两倍，因而我摔倒了。“天哪，”我大声说，“重力改变了，看来走路也的确需要练一练了。”过了一会儿，我才掌握了走路的诀窍，这才开始感到自如了。摆脱月球引力不想摆脱地球引力那样痛苦。但是返回到地球的经历却是非常吓人的。我们惊奇地看着，随着丢引力的增加，宇宙飞船的外层燃烧起火。当我们回到地面时，我们又感到被重重地推到在座位上。我说道：“真是精疲力竭了，但也很激动人心。关于引力，我现在就懂得更多了。你认为下次我们可以上星球上去参观吗？”“当然可以，”他笑着说，“你想到那颗星球上去呢？”望采纳！谢谢～
