　　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，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(災難)．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．

　　After a serious earthquake happened, a father left his wife safely at home and rushed to his son's school, only to find that the building where his son studied had collapsed and looked like a pancake．

　　He was shocked．He didn't know what he should do for a while, then he remembered the words he had said to his son, “No matter what happens, I'll always be there for you!” And tears began to fill his eyes．He started digging through the ruins(廢墟)．

　　As he was digging, other helpless parents and the firemen arrived and tried to pull him off the ruins, saying, “It's too late! They’re all dead! There's nothing you can do!” To them he replied with one line, “Are you going to help me now?” And then he kept on digging．

　　No one helped, however．He went on alone because he needed to know for himself：“Is my boy alive or is he dead?” He dug for eight hours…12 hours …24 hours… 36 hours…then, in the 39th hour, he pulled back a rock and heard his son's words．He shouted his son's name, “ARMAND!” He heard back, “Dad! ? ! It's me, Dad! I told the other kids not to worry．I told them that if you were alive, you'd save me and when you saved me, they'd be saved．You promised, ‘No matter what happens, I'll always be there for you! ’ You did it, Dad!”

　　“What's going on in there? How is it?” the father asked．

　　“There are 14 of us left out of 33, Dad．We’re frightened, hungry, thirsty and thankful you’re here．When the building fell down, it made a triangle(三角), and it saved us．”

　　“Come out, boy!”

　　“No, Dad! Let the other kids out first, because I know you'll get me! No matter what hap pens, I know you'll always be there for me!”

　　On a cold winter afternoon, I was walking home from a supermarket．I was feeling a little tired, as I was carrying my shopping bags．They were so heavy that I decided to stop to have a rest in the park．I walked towards the gate of the park．I noticed a poor man walking out of the restaurant in front of me．He was holding a paper bag．He walked to a nearby dustbin and started looking through it．

　　I suddenly felt sad．I knew this man would take all that he could get．so I went up to him and gave him some fruit．The man, with wrinkles(皺紋)on his face．looked up in surprise and took what I gave him．

　　A big smile appeared on his face and I felt very happy．Then he said,“Wow! First someone gave me this sandwich, then this drink, and now some delicious fruit．This is my daughter's lucky day．Thank you, boy．”Then he went away, singing a song．

　　Just then, I understood what the saying“Giving is getting”really meant．Everyone in the world needs help, everyone can offer help and everyone will be helped by showing kindness．Giving sometimes doesn't cost much, but it means a lot to the people who you help．

　　The man's happiness at that moment comes into my mind every time I have the chance to help others．
