閱讀理解

One large dinosaur hid in the thick jungle （熱帶雨林）. With small， hungry eyes he watched a larger dinosaur， about 90 feet long！ It was eating grass by a lake.

The one in the jungle stood 20 feet tall on his powerful back legs. His two front legs were short， with sharp claws on the feet. His teeth were like long knives.

There was only one hope for the grass-eating dinosaur. Even though he was three times as large as his enemy， he was not a fighter. He could only try to get away， into deep water， where he could be safe.

The grass-eater tried to move fast. But the enemy was faster. His three-toed footprints show that he came closer and closer.

We cant be sure how the fight ended. We can only tell by the animals footprints that the fight did take place. The mud where the two dinosaurs walked has turned into stone.

Footprints are not all that tell us about dinosaurs. Their bones and teeth have also been found. We even have some of their eggs in museums.

Scientists know how to fit a dinosaurs bones together. Then they can tell how the animal may have looked. From its teeth they know whether it ate meat or grass.

Dinosaurs were of many sizes and shapes. Some were as small as chickens. But all of them had very small brains.

Millions of years ago， the dinosaurs ruled the earth. Since then， there have been no dinosaurs. What happened to them？

We know they did not all die at once. It may have taken a few million years for all of them to die.

In the days of the dinosaurs， the whole earth was warm and wet. There were many green jungles. But the earth changes slowly. When parts of the earth became cold and dry， the jungles were becoming less and less. Then dinosaurs could not find enough to eat. This must be one reason why the dinosaurs died out.
