   阅读部分
   海平面说:气候变冷,温度下降,导致ice sheets形成,导致海平面下降
   陨石撞击说:小行星撞击地球,灰尘遮住太阳
   超强紫外线说:太阳暴走,臭氧层破坏,太阳紫外线UV过强,强杀死一种生活在表层surface of de ocean的Tri水生生物(注:推测:可能是古生物trilobite三叶虫)。化石为证,一种海洋生物那时候在海洋表面绝迹了
   听力部分
   冰川期海平面降低是漫长的过程,有几千年,气候变冷很缓慢,不会造成大灭绝。生物灭绝是在奥陶纪初期瞬间开始的,那个时候海平面还没那么低
   小行星撞击要残留下坑impact crater和radium deposit,但是目前没发现那个时期的crater
   化石的那种生物现在还有,而且形成化石的那种海洋生物具体在哪生活,我们不确定,可能生活在海底更深的地方。紫外线只能杀死地球表面的生物。杀不死Tri水生生物
