     The dinosaurs once lived happily on the earth. But 65 million years ago, they suddenly died out. What

happened to them?

     Scientists think that a change in temperature may be to blame. They have come up with lots of ideas

to explain the end of the dinosaurs. 

     The most famous one is the minor planet (小行星) idea. Let's go back to that day 65 million years ago

to see what happened. Everything was OK before a large minor planet suddenly hit the earth. What a

terrible hit! It caused big fires, storms, acid rain (酸雨), and even earthquakes and volcano eruptions. The

hit produced a lot of dust, which flew up into the air and blocked the sun for months. The earth became

very cold without sunlight. The plants died first. Then the grass eating animals died of hunger. Then the

meat eating animals could not find food, either. They began to eat each other, but after a while they died

out, too. The dinosaurs, either plant-eaters or meat-eaters, did not live through the disaster. What a sad

story !

     In April, a British scientist thought of a new idea about the death of the dinosaurs.

     He thinks that after the minor planet hit the earth, the temperature change left more dinosaur

boys than girls! Without enough female dinosaurs to hatch the eggs, the dinosaur population became

smaller and smaller.
