職稱英語考試綜合類2023年閱讀理解例題精解 300 million years ago.　　B) 250 million years ago.　　C) 60 million years ago.　　D) 65 million years ago　　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.　　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.　　解標題：Older Volcanic Eruptions　　本文講的是遠古火山噴發,所以older volcanic eruptions應是核心詞。　　1. Why did older volcanic eruptions do more damage than more recent ones?　　A. Because they killed off life more easily.　　B. Because they were brighter.　　C. Because they were larger.　　D. Because they were hotter.　　分析：細節題。第一題，一般在開頭段落尋找答案。　　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.　　句子是說：古代的火山更具殺傷力，不是因為它們更大，而是因為它們釋放出來的二氧化碳更容易把人殺死。所以答案A表述的內容同本段相符。　　2. How did Wignall calculate the killing power of those older volcanic eruptions?　　A. By estimating how long they lasted.通過估計他們持續多長時間。　　B. By counting the dinosaurs they killed.通過數死去的恐龍的的數量　　C. By studying the chemical composition of lava.通過研究熔巖的化學構成。　　D. By comparing the proportion of life wiped out with the volume of lava produced.通過比較火山釋放出的熔巖的體積與殺死生命的比例。　　分析：毫無疑問這是細節題，核心詞就是人名：Wignall。　　Paul 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?恐龍什么時候滅絕的?　　A) 300 million years ago.　　B) 250 million years ago.　　C) 60 million years ago.　　D) 65 million years ago　　分析：這是標準的細節題，核心詞：dinosaurs become extinct。而且這題的特點就是數字，所以在接下來的段落中大家要用筆標出所見到的數字加以判斷!　　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：題目就告訴我們這是一道推斷題，是第三段。這是一道比較難的題目。需要大家要讀懂句子，還要有推理能力：　　相關的句子：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.　　主要句子是說：Wignall忽略了6千5百萬年前恐龍的滅絕是否跟火山爆發有關，而其他很多科學家都認為恐龍的滅絕是受一顆小行星的影響。這就可以說明科學家們關于恐龍滅絕的原因是由爭議的，因此選擇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：通過題目分析這是一道主旨題。相當于在文章里尋找中心句。其實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.
