VOA慢速英语:Small Dinosaur Suffered from Jaw Tumor(翻译)

For the first time ever, scientists have discovered a tumor in the remains of a dinosaur.
科学家首次在恐龙的遗骸中发现了肿瘤。

Researchers at the University of Southampton in England found the deformed jaw of a dinosaur. The smaller-than-normal dwarf dinosaur is called a hadrosaur. It is a duck-billed dinosaur.
英格兰南安普敦大学的研究人员发现一只恐龙的下颚发生了变形。它的形体小于正常的恐龙，叫做鸭嘴龙。它是一种嘴像鸭子的恐龙。

The hadrosaur lived nearly 67 to 69 million years ago. It was found in what is called the “Valley of the Dinosaurs.” That valley is in the Transylvania area of western Romania.
鸭嘴龙生活在6700到6900万年前。它在恐龙谷被发现。恐龙谷位于罗马尼亚西部的特兰西瓦尼亚区域。

Dr. Zoltan Csiki-Sava was involved in finding the diseased hadrosaur. To investigate the tumor, her team was invited to Micro-CT scan the jawbone.
佐尔坦教授参与了这次患病恐龙的研究。为了研究它的肿瘤，佐尔坦教授的团队利用微型CT成像系统来观测它的下颚骨。

“The tumor in this dinosaur had not developed to its full extent at the moment it died,” the doctor said. “[The tumor] could have indirectly contributed to its early demise.”
医生称：在这只恐龙死之前，其肿瘤并未发育成型。但肿瘤可能对恐龙的夭折有间接影响。

Kate Acheson is a PhD student researcher at the University of Southampton. She said the duck-billed dinosaurs were at higher risk for tumors than other dinosaurs.
凯特是南安普敦大学的学生。她表示鸭嘴龙比其他恐龙更容易得肿瘤。

The tumor is known as an ameloblastoma. That is a benign non-cancerous tumor that is found in the jaws of human and other animals.
这种肿瘤在医学上叫做成釉细胞瘤。它是一种良性的非癌变肿瘤，在人类和其他动物身上均有发现。

Researchers say the dinosaur likely did not suffer any pain during the early stages of the tumor. The dinosaur died before being fully grown. Researchers are not sure if the tumor caused the death of the hadrosaur.
研究人员表示在肿瘤的初期阶段，这只恐龙并未遭受很多痛苦。而他死去时，其肿瘤并未成型。研究人员尚无法确定是否肿瘤是导致鸭嘴龙死去的原因。
