10、5BDCABTask 2再次阅读“How life began on the earth”，然后完成下面的图表。答案：1.Water2.Land animals3.Human beings.请将课文“How life began on the earth”译成汉语，然后参考译文助读自主勘误译文助读地球上的生命是怎样形成的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，一种普遍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星体。大爆炸后好几十亿年过去了，但地球还只是一团尘埃。以后它会变成什么没人能知道，直到

11、3845亿年前，这团尘埃才慢慢地形成一个固体的球状物。地球(开始)变得激烈动荡，不知道这个固体形状是否会继续存在下去。它(地球)猛烈的爆炸喷出了烈火与岩石，最终产生了碳、氮气、水蒸气和其他多种气体，从而形成了地球的大气层。更为重要的是，地球冷却下来后，地球的表面就开始出现了水。在火星这些其他行星上都出现了水，但和地球不同的是，这些水后来都消失了。水会对生命的发展起关键作用，这一点在当时并不明显。很多科学家相信，由于地球上长期有水存在，使得地球得以把有害气体和酸性物质溶解在海洋里。这就产生了一系列的反应，使得生命就有可能开始发展了。好几百万年以后，水的表面开始出现了极小的植物。它们繁殖起来就使得

12、早期的海洋充满了氧气，这为早期的贝类及其他各种鱼类的发育进一步创造了条件。接着，绿色植物开始出现在陆地上。随后，陆地上出现了动物，其中有一些是昆虫，另外一些叫两栖动物，它们既能在陆地上生活，也能在海洋里生存。后来，当植物长大成了森林的时候，爬行动物出现了。它们一般是通过孵蛋繁衍后代的。再后来一些叫作恐龙的巨型动物出现了。它们也生蛋，在地球上生存了1.4亿年。然而，6 500万年前，恐龙时代结束了。它们为什么会突然灭绝至今仍是个谜。恐龙的灭绝使地球上哺乳动物的产生有了可能。哺乳动物不同于以往所有的生物形式，因为他们能从体内生产出幼仔并给幼仔哺乳。最后，大约260万年前，一些小巧聪明，就是现在这些

13、长着手脚的动物出现了，他们散布在地球的各个地方。于是他们接着成为这个行星上最重要的动物。然而，他们对地球却不怎么在意，他们把过多的二氧化碳释放到大气层中，这使得地球上的热不能释放到太空中去。因此许多科学家相信地球可能会因此变得太热而不适合生物的生存。所以，在未来的数百万年中，生命能否在地球上延续取决于这个问题能否得到解决。,.课文精选段落背诵，请注意意群、连读和升降调How life began on the earthFor several billion years after the “Big Bang”/，the earth was still justa cloudof dust./
