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 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. 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.

Ⅲ 英語必修3第四單元課文翻譯

沒有人知道地球開始到底如果，因為它不是發生在不久之前。然而，根據一項被廣泛接受的理論，宇宙始於"大爆炸"令此事全方位方向發展。這之後，原子開始形成，並結合創建星級和其他機構。

幾億年後， "大爆炸" ，地球還只是塵埃雲。什麼是成為未卜，直到介乎4.5至38.0億年前，當塵埃落定成固體地球。地球變得如此暴力說，不清楚是否會形成去年與否。爆炸大聲與消防和搖滾。他們在時間，以產生碳，氮，水蒸氣和其他氣體，其中，使地球的大氣層。什麼是更重要的是，作為地球冷卻下來，水開始出現在其表面。

水也出現在其他星球如火星，但不像地球，它已消失了。現在尚不明顯，水，是從根本上為發展的生活方式。許多科學家相信的是，持續存在的水，使地球解散有害氣體和酸性物質進入海洋。這產生了連鎖反應，這使我們可以為生活去發展。

許多百萬年來後，第一個非常小的植物開始出現在水面上。他們成倍增加，填補了海洋與氧氣，這一切鼓勵後來的發展，早在貝類和各種魚類。其次，綠色的植物開始生長的土地。他們在隨後的時間，由土地動物。有的昆蟲。其他人，所謂兩棲類，分別為能獨立生活的土地，以及在水中。後來，當植株生長成森林，爬行動物首次出現的時間。他們製作的，一般青少年所產卵。這之後，一些巨大的動物，所謂的恐龍化石是發達國家。他們開出的雞蛋太，並存在於地球上超過1.4億年。不過，六千五百萬年前的年齡恐龍結束。他們為何突然失蹤，仍是一個謎。這起失蹤可能上升的哺乳動物對地球。這些動物均不同於所有的生命形式，在過去，因為他們生下女嬰年輕動物和生產的牛奶養活他們。

最後，大約2.6萬年前，有些小聰明的動物，現在手和腳出現，並蔓延整個地球。因此，他們已在輪到自己，成為最重要的動物星球。但他們沒有照顧到地球是很清楚的。他們把太多的二氧化碳進入大氣層，以防止熱逃走從地球到太空。由於這一點，許多科學家認為，地球可能成為太熱，以現場直播。所以，無論生活中，將繼續對地球數百萬年來，將取決於是否有這個問題就可以得到解決。

a visit to the moom上個月我很幸運地和我的朋友李燕萍，一位宇航員進行了一次太空之旅。我們在飛船里參觀了月球。
在我們離開之前，李燕萍向我解釋在我們的旅行中重力將會改變3次，並且第一次將會非常厲害。然後我們出發了。隨著火箭升入大氣，我們被彈回自己的座位因為我們盡力擺脫地球的重力。我們不能與對方講話，因為這太難了。漸漸地體重減少了，並且我能與他交談「為什麼飛船沒有掉到地面？在地球上如果我從樹上掉下來就會摔在地上」「我們現在離地球太遠了以至於能忽略它的拉力」他解釋道，「因此我們就會感覺這里好像沒有重力一樣。當我們離月球更近一點時，我們將會感覺到它對我們的拉力，但他並不像地球對我們的那樣強」我馬上振奮起來，在失重的太空艙里漂浮著看著地球越來越小月球越來越大。
當我們到的時候，我迫不及待地想要去探索。「快來」我說「如果你是對的，我的體重將會比在地球上要輕因為月球比地球小因此我可以很輕松地移動。如果我在這呆的時間足夠長，我將會變得更高。我當然會更輕！」我笑著從飛船上爬下來。但當我想往前走時，我發現我走了在地球上的兩倍並且摔倒了。「哦，天哪！」我尖叫，「因為重力改變了，需要一些走路的練習。」過了一會兒我找到了竅門然後開始了。
離開月球的重力並沒有像離開地球時那麼難過。但是回地球時非常嚇人。我們看著，驚訝的看著當地球的重力增加時飛船外面起火了。當我們再一次被彈回自己的座位時我們著陸了。「這非常累但也很刺激，」我說「現在我知道了更多關於重力的知識了。你認為我們下次可以參觀一些星球嗎？」「當然，」他笑著說「你想要參觀哪個星球呢？」

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?"

Ⅵ 求外語教學與研究出版社 英語必修三第四單元第二篇課文是the green movement發清楚的

Cultural Corner
The Green Movement
Some countries are better than others at looking after the environment. In Europe, Germany and the northern European countries work very hard to improve the environment. People in countries such as Germany put their garbage into different bags—paper in one bag, plastic in another bag, etc. The garbage is then taken away and, if possible, recycled. CFCs (chlorofluro-carbons), chemicals which are found in refrigerators and aerosol cans, are not allowed. There are laws that do not allow people to burn too much coal.
In the 1970s, as people learnt more about environmental problems, the "Green" movement began and soon spread all over Europe. The "Green" movement tries to get governments to think seriously about the environment and how to look after it. It collects information about how instry is damaging the environment and gives this information to newspapers.

Ⅶ 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。
