Because they were hotter.　　分析：细节题。第一题，一般在开头段落寻找答案。　　Volcanoes were more destructivein ancient history, not because they were bigger, but because the carbon dioxidethey released wipedout擦去、抹去 life生命 greater ease.　　句子是说：古代的火山更具杀伤力，不是因为它们更大，而是因为它们释放出来的二氧化碳更容易把人杀死。所以答案A表述的内容同本段相符?！　?. How did Wignall calculate the killing power of those older volcanic eruptions?　　A. By estimating how long they lasted.通过估计他们持续多长时间?！　. By counting the dinosaurs they killed.通过数死去的恐龙的的数量　　C.

By comparing the proportion of life wiped out with the volume of lava produced.通过比较火山释放出的熔岩的体积与杀死生命的比例?！　》治觯汉廖抟晌收馐窍附谔?，核心词就是人名：Wignall?！　aul Wignallfrom the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do . He calculated the killing efficiency for these volcanoes by comparingthe proportionof life they killed off with the volume of lavathat they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.　　3. When did dinosaurs become extinct?恐龙什么时候灭绝的?　　A) 300 million years ago.　　B) 250 million years ago.　　C) 60 million years ago.　　D) 65 million years ago　　分析：这是标准的细节题，核心词：dinosaurs become extinct。而且这题的特点就是数字，所以在接下来的段落中大家要用笔标出所见到的数字加以判断!　　The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide. The global warming that followed wiped out 80 per cent of all marine genera at the time, and it took 5 million years for the planet to recover. Yet 60 million years ago, there was another huge amount of volcanic activity and global warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years. The most recent ones hardly have an effect at all, Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.　　4.What can be inferred from paragraph 3 concerning dinosaurs?　　A) They were killed off by an asteroid.　　B) They died of drastic climate change.　　C) They were wiped off by a volcanic eruption.　　D) The cause of their extinction has remained a controversial issue.　　分析：题目就告诉我们这是一道推断题，是第三段。这是一道比较难的题目。需要大家要读懂句子，还要有推理能力：　　相关的句子：The most recent ones hardly have an effect at all, Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.　　主要句子是说：Wignall忽略了6千5百万年前恐龙的灭绝是否跟火山爆发有关，而其他很多科学家都认为恐龙的灭绝是受一颗小行星的影响。这就可以说明科学家们关于恐龙灭绝的原因是由争议的，因此选择D。　　5. What is the main thesis of the article?　　A) Volcanic eruptions are not always deadly.　　B) Older volcanic eruptions were more destructive.　　C) Carbon dioxide emissions often give rise to global warming.　　D) It is not easy to calculate the killing power of a volcanic eruption.　　分析：通过题目分析这是一道主旨题。相当于在文章里寻找中心句。其实文章第一段就是中心：Volcanoes were more destructive in ancient history, not because they were bigger, but because the carbon dioxide they released wiped out life greater ease.
