美国博物馆展出恐龙化石
Dinosaurs Live Again at an American Museum
Many millions of years ago, the last dinosaurs lived in what is now the American West.Now, scientists studying dinosaur fossils have documented what happened to the ancient creatures.An exhibit showing some of the results has opened at the Smithsonian Institution in Washington, D.C.
几百万年前，最后的恐龙生活在现今美国西部。现在科学家们正在研究保存的恐龙化石以了解远古生物的更多事情。华盛顿史密森学会的一个展览展示了一些研究结果。
The dinosaurs delight seven-year-old Ella Smith. She says, "They are very old and cool and very big."
恐龙让七岁的Ella Smith很兴奋。她说，“它们很久远，很酷，非常大。”
Ella and her mother Paige have found themselves in a room that re-creates the world just before an asteroid struck.Many scientists believe that asteroid destroyed the dinosaurs and nearly everything else.
Ella和母亲Paige在一个厅里观看它们，这是在小行星撞击之前形成的世界。许多科学家认为小行星毁灭了恐龙和其他一切事物。
Kara Blond directs exhibitions at the Museum of Natural History.She says Ella and her mother have only seen a preview of what will be shown five years from now in the new National Fossil Hall.
Kara Blond在自然历史博物馆指导展览。她说Ella与其母亲看到的是新国家化石馆展示的一个预览，五年内还会有更多展览。
"The New Fossil Hall will tell the grand sweep of life on Earth over time. This is one little 2,000,000-year part of that.But it gives us a real window into how people understand science and how they interpret the stories."
新化石馆将描述地球上生物消亡的时段。这是那200万年中的一小部分。但它给了我们一个真实窗口去研究人们如何理解科学，以及如何解释这些故事。”
She says a few ancient creatures and their ways of living will be the basis of that exhibit.
她说一些古生物与其生活方式将是展览的根本。
"We use a couple of our major specimens as the anchors for the story.And we deconstruct the world that they lived in by looking at the mechanics of how they lived, how they ate, who they lived with, what plants they fed on."
“我们使用几个主要的标本作为故事的落脚点。我们描述它们生活的世界，看它们如何生活的技巧，它们怎样吃，与什么一起生活，它们吃什么样的植物。”
These dinosaurs existed in what is now the arid – very dry – American West. But in their time the area had a seaway.The deltas extending from that seaway turned out to be a perfect place for the animals to die.Over time, some of their remains became fossils. That is why the area is now rich in fossils.
这些恐龙生活在现在非常干旱的美国西部。但在它们生存的时代这个地区有一个航道。这个三角洲从海道中扩展出，成为死去动物的一个完美场所。随着时间推移，它们的一些残骸成为了化石。这就是为什么现在该地区有丰富的化石。
Kay Behrensmeyer set up the exhibition. She says the uncovered remains also document the birds, small mammals and reptiles that survived after the dinosaurs died off.
Kay Behrensmeyer开设了这个展览。她说发现的残骸也记录了鸟类，小型哺乳动物和爬行动物，这些在恐龙灭绝后幸存下来。
"Turtles survived. There are many aquatic ones. If they were hiding out in the water, they had more of a chance to do that to get through.And earthworms, we actually have arrows from earthworms that are an inch or two above the impact layer."
“海龟存活了。有许多水生的动物。如果它们躲在水里，它们有更多机会生存。还有蚯蚓，我们实际上有来蚯蚓化石，在一或两英尺的冲击层。”
That layer can be seen in a piece of rock in the exhibition area. It shows when the asteroid hit, causing the animals to die.
在展示区该层可以在一块岩石被看到。它显示了当小行星击中时，导致了动物死亡。
Museum fossil hunters continue to send back what they dig up in the field.Some make it to the Fossil Lab, which is behind glass windows in the exhibit.Visitors can watch scientists as they study and prepare the remains.
博物馆的化石发掘者继续发送回他们挖到的化石。一些被送到化石实验室，这些被展示在玻璃窗后面。游客可以看到科学家的研究和准备。
This is where volunteer Bill King sorts through ancient bones of an ancient crocodile – a land and water animal.
志愿者Bill King通过各种古老的骨头分辨一只古老的鳄鱼，这一种生活在陆地和水域的两栖动物。
"It’s just really interesting. It is like a crime scene investigation, only there wasn’t any crime.It’s just nature and millions of years ago. And we get to do it all, hands on, at no charge."
“这真的很有趣。它像一个犯罪现场调查，只是没有犯罪。它只是亿万年前的自然世界。我们要亲自做这一切，无偿的。”
The flowering of the planet after the dinosaurs shows that the Earth is resilient and can regenerate – be fertile again – over time.But Kay Behrensmeyer says human beings are now producing fast changes in the environment.She says that with that knowledge, people need to guard that environment so future regeneration can continue.
恐龙之后地球的变化证明地球有弹性，具有再生性，随着时间推移而重新丰富。但是Kay Behrensmeyer说人类现在在环境中制造快速的变革。她说人类有知识，人类需要保护环境，因而未来的再生可以继续。
Four-year-old Nathanial Paul is learning that lesson now.
四岁的Nathanial Paul现在正学习这一课。
Mike Paul: "Why do you love the dinosaurs so muc."
Mike Paul：“为什么你这么喜欢恐龙？”
Nathanial Paul: ‘Cause I want to learn more about them."
Nathanial Paul：“因为我想更了解它们。”
Mike Paul: "Because you want to learn more about them."
Mike Paul：“因为你想更了解它们。”
That should please the exhibit’s organizers. They hope visitors leave the museum with greater understanding of creatures that depended on the environment – just like us humans.
那应该会使展览组织者高兴。他们希望游客离开博物馆时会有更多了解，对于依赖环境的生物，它们也像人类一样。
