课文译文
在地球漫长的历史中，许多动物都消失了。这些动物中最著名的就是恐龙。数千万年前，恐龙在地球上生活，比人类的出现要早得多，那时，它们的未来似乎是安全的。恐龙有许多不同的种类，其中有很多曾生活在中国。25个种类的恐龙蛋是在河南省南阳西峡县发现的。不久前，在辽宁省朝阳县发现了一种罕见的、形状像鸟的新的恐龙物种。当科学家们观察它们的骨头时，他们惊奇地发现它们不仅能像其他恐龙一样可以跑，而且还可以爬树。他们是从恐龙骨头的连接方式上得知这一点的。
大约6 500万年前，恐龙突然灭绝了。一些科学家认为恐龙灭绝是发生在一次意外事件之后，当时太空中的一块巨石撞击地球，在空气中扬起了太多的灰尘。另一些科学家则认为，地球变得太热了，恐龙无法再(在地球上)继续活下去了。没有人确切地知道恐龙是为什么又是如何在那么短的时间内从地球上消失的。
我们知道最近有许多其他的野生植物、动物、昆虫和鸟类已经灭绝了。根据联合国的一份报告，在过去的500年里，大约有844种动植物已经消失了，渡渡鸟就是其中的一种。渡渡鸟生活在毛里求斯岛上，是一种非常友好的动物。请听一个关于渡渡鸟的故事，看看它是如何从地球上消失的。
