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.

Reading 2 Last month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!
Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth's gravity. It was so hard that we could not say anything to each other. Graally the weight lessened and I was able to talk to him. "Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground." I asked. "We are too far from the earth now to feel its pull," he explained, "so we feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth's." I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.
When we got there, I wanted to explore immediately. "Come on," I said. "If you are right, my mass will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!" I laughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. "Oh dear," I cried, "walking does need a bit of practice now that gravity has changed." After a while I got the hang of it and we began to enjoy ourselves.
Leaving the moon's gravity was not as painful as leaving the earth's. But returning to the earth was very frightening. We watched, amazed as fire broke out on the outside of the spaceship as the earth's gravity increased. Again we were pushed hard into our seats as we came back to land. "That was very exhausting but very exciting too," I said. "Now I know much more about gravity! Do you think we could visit some stars next time?" "Of course," he smiled, "which star would you like to go to?"

6. 高一英語必修3 第四單元的課文全文翻譯 題目為 How life began on the earth

沒有人確切地知道地球是如何開始的，因為那是好久以前的事了。然而，根據廣泛接受的理論，宇宙始於「大爆炸」，把物質在所有的方向。在那之後，原子開始形成並結合成恆星和其他天體。
對於「大爆炸」後數十億年，地球還只是一團塵埃。什麼是成為不確定直到4.5至3800000000年前，當塵埃落定成固體地球。地球變得如此暴力，也不清楚是否形狀將持續。它的爆炸噴出了烈火和岩石。最終產生了碳，氮，水蒸氣和其他的氣體，從而形成了地球的大氣層。更重要的是，當地球冷卻下來，水開始出現在其表面。
水也出現在其他行星火星一樣但不像地球，它已經消失了。這是不能立即明顯，水是生命發展的基礎。很多科學家相信，水的持續存在使得地球把有害氣體溶解在海洋里。這產生了連鎖反應，使生命發展成為可能。
數百萬年後，第一個非常小的植物開始出現在水面。他們繁殖起來，使得海洋充滿了氧氣，這鼓舞了後來發展早期貝類和各種魚類。其次，綠色植物開始成長的土地上。他們在之後的時間由陸地動物。有些昆蟲。其他人，叫兩棲動物，能夠在陸地上生活以及在水。後來當植物長成的森林，爬行動物第一次出現。他們通常為卵生。之後，一些巨大的動物，所謂的恐龍，開發。它們產卵也和地球上存在超過140000000年。然而，65000000年前恐龍時代的結束。他們為什麼突然消失，仍然是一個謎。這個消失的崛起成為可能的哺乳動物在地球上。這些動物不同於所有生命形式的過去，因為他們生了年輕的動物寶寶和生產的牛奶喂它們。
大約2600000年前的最後一些小聰明的動物，現在手和腳，似乎遍布地球。他們就這樣，反過來，成為地球上最重要的動物。但他們不照顧地很好。他們把太多的二氧化碳釋放到大氣中，從而防止熱量從地球逃逸到太空。因此，許多科學家相信地球會變得太熱。所以生命是否會在未來的幾百萬年的地球上繼續將取決於是否可以解決這個問題。
