4、Blasts from the Past
1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease.
2 Paul Wignall from 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.
3 Wignall calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that 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.
4 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 8 per cent of all marine genera at the time, and it took 5 million years far tire planet to recover.
5 Yet 60 million years ago in the late Palaeocene 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 at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.
6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up and exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere.
7 Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignall's idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years.
8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide or sulphur dioxide emissions.
Older eruptions were more devastating____.
【单选题】

A.than more recent ones

B.the killing efficiency for older eruptions

C.has remained controversial

D.Wignall's calculations as acceptable

E.has been mown to us all

F.his ideas

正确答案:A

答案解析:more recent ones较后来的火山爆发。填入后生成的句子不仅在语法上是正确的并且跟文章第一句话的意思差不多。

5、Happy Marriage, Happy Heart
Happily married people have lower blood pressure than unhappily married people or singles, a Brigham Young University study says.
On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study.
"There seems to be some unique health benefits from marriage. It's not just being named that benefits health-what's really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.
The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The ____ recorded blood pressure at random intervals and provided a total of about 72 readings.
"We wanted to capture participants' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.
Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people.
"Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.
The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.
The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.
Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said.
