What Killed the Dinosaurs?

What Killed the Dinosaurs? Once upon a time, there were big dinosaurs living on Earth. Why did they go away? 很久以前，恐龍還活在地球上，那牠們為什麼消失了呢? Some people say a very big space rock hit the Earth in Mexico. The "kaboom" was so big that it hit all the dinosaurs. Did this happen? 據說是一顆超大的隕石墜落在墨西哥，讓所有的恐龍滅亡。真的是這樣嗎? Some smart scientists have another idea. They say the dinosaurs are gone because of volcanoes in India. 也有科學家覺得恐龍是因為印度的火山爆發而絕種。 Volcanoes are special mountains. They have holes on top! Volcanoes rumble and grumble. And they shoot out fire! 火山會隆隆作響，還會噴出火焰。 At the time of the dinosaurs, volcanoes shot out lots of fire and smoke. This happened for a very long time. This made the air very smelly. 當時有一段時間火山噴出大量火焰跟濃煙，讓空氣品質惡化。 After many years, the volcanoes changed the weather. The world got very cold. These scientists think this is why the dinosaurs are gone. 多年之後，火山爆發導致氣候變得很冷，科學家覺得這才是恐龍絕種的原因。 So, what made the dinosaurs go? Was it the volcanoes, the big space rock… or both? Scientists are not sure now, but their ideas are very interesting! 究竟是什麼原因讓恐龍消失呢? 是火山，是隕石，還是兩個都有? 科學家還不確定，但是他們的想法很有趣！ Today, scientists look for rocks and dinosaur bones in the ground. This helps them learn more about what happened to the dinosaurs! ---------------------------------------------------------------------------------------------------------------- Vocabulary 有一個理論說火山爆發導致氣候改變，恐龍也因此滅絕。 1. shoot 噴發 Can you imagine Datun Mountain erupting one day? 你能想像有一天大屯山爆發嗎? And shooting out fire and ash? 然後噴出火焰和灰塵? That would be so cool! 那好酷喔! No, it wouldn't. 才不呢。 2. because 因為 Our weather may change because the ash would block the sun.我們的天氣可能改變，因為火山灰會遮住太陽。 3. for a long time 長時間 But Datun Mountain has slept for a very long time. 但是大屯山已經沉睡很久了。 With volcanoes, you never know. 火山是說不準的。 4. scientist 科學家 I'm not worried. We have good scientists. 我不擔心，我們有很好的科學家。 Yeah, let's hope they don't fall asleep.對啊，希望他們不會睡著。 請跟我讀今天的單字。 shoot噴發 because因為 for a long time長時間 scientist科學家 ---------------------------------------------------------------------------------------------------------------- Quiz 1.
