ANIMAL EXTINCTION
Many animals have disappeared during the long history of the earth. The most famous of these animals are dinosaurs. They lived on the earth tens of millions of years ago, long before humans came into being and their future seemed secure at that time. There were many different kinds of dinosaur and a number of them used to live in China. The eggs of twenty-five species have been found in Xixia County, Nanyang, Henan Province. Not long ago a rare new species of bird-like dinosaur was discovered in Chaoyang County, Liao-ning Province. When scientists inspected the bones, they were surprised to find that these dinosaurs could not only run like the others but also climb trees. They learned this from the way the bones were joined together.
Dinosaurs died out suddenly about 65 million years ago. Some scientists think it came after an unexpected incident when a huge rock from space hit the earth and put too much dust into the air. Others think the earth got too hot for the dinosaurs to live on any more. Nobody knows for sure why and how dinosaurs disappeared from the earth in such a short time.
We know many other wild plants, animals, insects and birds have died out more recently. According to a UN report, some 844

animals and plants have disappeared in the last 500 years. The dodo is one of them. It lived on the Island of Mauritius and was a very friendly animal. Please listen to a story of the dodo and
how it disappeared from the earth.
动物灭绝
从地球有史以来的这段漫长时期，许多动物都消失了。这些动物中最有名的是恐龙。千百万年前，恐龙就在地球上生活，比人类的出现要早得多，当时它们的前景好像也很安全。当时有许多不同种类的恐龙，其中有很多种类曾经生活在中国。25个种类的恐龙蛋是在河南省南阳西峡县发现的。不久前，在辽宁省的朝阳县新发现了一种罕见的、形状像鸟一样的恐龙。科学家们观察它们的骨头时，惊奇地发现它们不仅跟其他恐龙一样可以跑，而且还可以爬树。科学家们是根据恐龙骨骼的连接方式得知的这些。
恐龙大约在6 500万年前突然灭绝了。有些科学家认为恐龙灭绝是发生在一件意外事故之后，当时宇宙间一块巨石击中地球因而在空气中扬起太多的尘土。另外一些科学家则认为，地球变得太热，因此恐龙无法在地球上生活了。没有人确切地知道恐龙是由于什么原因，又是怎样在这么短的时间里从地球上消失的。
我们知道，近来许多其他的野生动植物、昆虫和鸟类也灭绝了。根据联合国的一份报告，在过去500年里，有844种动植物消失。渡渡鸟就是其中的一种。它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。
