Chapter 1 The Mighty T. Rex Tyrannosaurus rex were huge, fierce animals that walked on two legs. They ruled the Earth about 67 to 70 million years ago. How do we know this? T. rex bones were first found around 1900. Then, parts of more T. rex skeletons were found. Scientific research was done on these fossils. In 1990, scientists made an exciting new discovery. It led to more information about these dinosaurs. Tyrannosaurus rex means " king of the tyrant lizards. "

第1章 强大的霸王龙 霸王龙是体型巨大、生性凶猛的两足动物。它们大约在6700万到7000万年前统治着地球。我们是如何知道这些的呢? 霸王龙的骨骼最早于1900年左右被发现。随后，人们又发现了更多霸王龙骨骼的部分化石。科学家们对这些化石进行了科学研究。 1990年，科学家们有了一个令人兴奋的新发现。这一发现让我们对这些恐龙有了更多的了解。 "Tyrannosaurus rex"的意思是“暴君蜥蜴之王"。

In 1990, Sue Hendrickson was part of an exploration for fossils in South Dakota. One day, Sue took a walk with her dog, Gypsy, to some nearby cliffs. Her group had not yet searched there. Sue found a few small bones on the ground. Then she spotted some huge bones sticking out of the cliff. Sue climbed up closer. She saw backbones and a leg bone. She noticed that the bones were hollow. This meant that they came from a meat-eating dinosaur. She knew T. rex had lived in this part of North America. Sue was excited by her important discovery. Sue made her discovery right before she and the fossil hunters were about to leave.

1990年，苏·亨德里克森参与了在南达科他州的一次化石探寻活动。有一天，苏带着她的狗吉普赛到附近的一些悬崖边散步。她的团队还没搜索过那个地方。 苏在地上发现了几块小骨头。接着，她看到一些巨大的骨头从悬崖上露了出来。苏爬上去走近查看。她看到了脊椎骨和一根腿骨。她注意到这些骨头是中空的。这意味着它们来自一种食肉恐龙。她知道霸王龙曾在北美的这个地区生活过。苏为自己的重大发现感到兴奋不已。 苏是在她和化石猎人们正要离开的时候做出这一发现的。

Chapter 2 The Dig Sue and a few other fossil hunters and paleontologists started to dig into these sandstone cliffs. They didn't use machines because they didn't want to harm the bones. Instead, Sue and her team used picks and shovels to remove the dirt and rock. After five days of teamwork, they reached the bones buried 30 feet down. Fossil hunters spend hours inspecting rock for fossils.

第2章 挖掘工作 苏和其他几位化石猎人与古生物学家开始挖掘这些砂岩悬崖。他们没有使用机器，因为他们不想损坏化石。相反，苏和她的团队用镐和铲子来清除泥土和岩石。经过五天的团队协作，他们到达了埋在地下30英尺深的化石处。 化石猎人们要花数小时检查岩石以寻找化石。

Then, Sue and the other fossil hunters had to work more carefully. They used smaller tools, including knives and brushes. They kept finding bones. Some of them were huge. The skull was about five feet long! The hunters found almost all of the bones. Most were in excellent shape. Those that were in danger of cracking were glued. Sue's team was able to dig out all of the bones in just 17 days! The hunters named this T. rex Sue. They named her after the woman who found her. However, scientists still do not know if this T. rex was male or female. Sue's enormous jaw held jagged teeth up to 12 inches long.

然后，苏和其他化石猎人不得不更加小心地工作。他们使用了包括刀和刷子在内的更小的工具。他们不断发现骨头。其中一些非常大。头骨大约有五英尺长!猎人们找到了几乎所有的骨头。大多数骨头保存状况极佳。那些有破裂危险的骨头被粘好了。苏的团队仅用了17天就挖出了所有的骨头! 猎人们将这具霸王龙命名为苏。他们用发现她的那位女士的名字来命名它。然而，科学家们仍然不知道这具霸王龙是雄性还是雌性。 苏巨大的下颚里长着长达12英寸的参差不齐的牙齿。
