The dinosaurs（恐龙）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,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（灾难）.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.
Esop was a very clever man.he lived in Greece many years ago.
One day a visitor asked him,"Kind man,can you tell me how long it will take me to get to town?"
"Go!"Esop answered.
"I know I must go,"said the visitor,"but I want to know how soon I can get there."
"Go!"Esop shouted at him.
The visitor was angry."This man must be mad,"he thought.Then he walked on.Suddenly he heard Esop shouting."You will get there in two hours!"
The visitor turned back and asked,"Why did not you yell me that before?""How could I tell you that before?"answered Esop."I did not know how fast you could work."
Strange things happen from time to time when you travel because people divide（划分） the earth into twenty-four time zones（时区）,one hour apart．You can have days with more or fewer than twenty-four hours,and weeks more or less than seven days．If you make a five-day trip across the Atlantic Ocean（大西洋）,your ship enters a different time zone every day．As you enter each zone,the time changes one hour．If you travel westward,you set your watch back；and if you travel eastward,you set it ahead．Each day of your trip has either twenty-five or twenty-three hours．If you travel by ship across the Pacific（太平洋）,you cross the International Date Line． By agreement（协定）a new day begins at this line．When you cross the line,you change your calender（日历）one full day,backward or forward．If travel eastward,today becomes yesterday,if westward,it is tomorrow．
