恐龙。 伊丽莎白·奥斯汀 撰文 葆拉·施里克、诺拉·武提斯 绘图 思考问题： 关于恐龙和它们生活的世界，人们都了解到了哪些知识

The World of Dinosaurs Imagine that you've been sent back in time 230 million years. The world looks very different from the one you know. All the land on earth is one giant continent. Shallow seas cover parts of the ground. The weather is warm, even near the poles. In the shadow of an enormous plant, you hear a noise. Something large is hiding there.

恐龙的世界 想象一下，你穿越回了2.3亿年前 那时的世界和你现在熟悉的世界完全不同 地球上所有陆地连在一起，是一块巨大的大陆 浅海覆盖了部分陆地 气候十分温暖，哪怕极地附近也不冷 在一棵巨型植物的树荫下，你听到一阵声响 有个大家伙正藏在那儿

You have arrived in the time of the dinosaurs. You are probably familiar with dinosaurs from books and movies. These animals were just one part of an entire ancient world. The age of dinosaurs lasted for about 180 million years. Earth changed a lot during that time. The continents split apart and the first flowering plants grew.

你已经来到了恐龙生活的时代 你大概早就从书本和电影里认识了恐龙 这些动物不过是那个完整远古世界的一小部分 恐龙时代一共持续了大约1.8亿年 这段时间里，地球发生了巨大的变化 大陆分裂开来，最早的开花植物也生长出来了

Some kinds of dinosaurs died out, and new ones appeared. Like today's world, the world of the dinosaurs was a changing place.

一些种类的恐龙灭绝了，新的恐龙又出现了 和现在的世界一样，恐龙的世界也一直在不断变化

Meet the dinosaurs. Dinosaurs were a kind of reptile that is now extinct. Dinosaurs stood up off the ground while other reptiles crawled. They had large eyes and could probably see color. Many scientists think that dinosaurs were faster and more active than other reptiles. With the help of these traits, dinosaurs spread across Earth.

认识恐龙 恐龙是一类如今已经灭绝的爬行动物 和其他贴地爬行的爬行动物不同，恐龙可以直立起身 它们长着大大的眼睛，很可能能分辨颜色 很多科学家认为，恐龙比其他爬行动物动作更快、更活跃 靠着这些特点，恐龙遍布了整个地球

At least 1 ,000 species of dinosaurs have been discovered and named, but scientists think far more lived on Earth. Dinosaurs could be as small as a chicken or as large as a school bus. Some grew as long as 39 meters, 128 feet. Everything we know about dinosaurs and their world comes from fossils. A fossil is the remains or print of a plant or animal that was preserved in soil or rock. Scientists have found parts of preserved dinosaur skeletons. They have found only a few whole dinosaur skeletons.

人们已经发现并命名了至少一千种恐龙，但科学家认为地球上曾生活过的恐龙远不止这些 恐龙小的只有小鸡那么大，大的却有校车那么大 有些恐龙体长能达到39米，也就是128英尺 我们对恐龙和它们世界的所有了解，都来自化石 化石是保存在土壤或岩石里的远古动植物遗骸或印记 科学家发现过不少保存下来的恐龙骨骼碎片 完整的恐龙骨架，他们只发现过很少几具
