英语翻译
Millions of years ago,dinosaurs (恐龙) lived on earth.At that time,the whole earth was warm and wet.There were green forests and they could find enough to eat.
Gradually（渐渐地）,parts of the earth became cold and dry and the forests there died.Then dinosaurs could not find enough to eat.This must be one reason why dinosaurs died out (灭绝).
There may be other reasons that we do not yet know about.Scientists are trying to make more discoveries（发现）about dinosaurs.
We now know that dinosaurs were of many sizes and shapes.Some were as small as chickens,while some were about 90 feet long.
There were also terrible fights（战争）between dinosaurs!They might have happened more than 100 millions years ago.Though no man was there to see any of the fights,we can tell by the animals’ footprints that fights did happen.

英语翻译
Long long ago ,dinosaurs ruled Earth .We now know a lot about the many different types of dinosaurs because scientists have found many dinosaur bones .However ,around 65 million years ago ,all the dinosaurs suddenly disappeared .People argue about what really happened to them .
Some scientists believe that dinosaurs died out because there was sudden temperature change on Earth .But what could have caused this huge change
Many people believe that Earth might have been hit by a really large rock ,or even a very small planet .Scientists have even found a 200-kilometre-wide hole in Mexico .They think it might be the place where a small planet hit Earth .If a small planet hit Earth ,it would have caused many problems for the dinosaurs ,including storms ,fire ,acid rain and earthquakes .All of these would have released a lot of dust into the air .The dust would have been so thick that it would have been impossible for the dinosaurs to see the sun .Without sunlight ,it would have been too cold and dark for plants to grow .When plants died ,The plant-eating dinosaurs would have had nothing to eat and die .The meat-eating dinosaurs would also have become very hungry .They may even have become so hungry that they ate each other .Without enough food for all the dinosaurs ,they would have begun to disappear quickly .
But some people do not agree with these explanations of why the dinosaurs died out .Some scientists think that a huge volcano eruption may have killed the dinosaurs ,while others believe that the dinosaurs died as Earth slowly got colder and colder .Although they have disappeared dinosaurs continue to fascinate people .
