1、Blasts from the Past1 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" fｏｒthese volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size fｏｒsize, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.4 The Permian extinction, fｏｒexample, 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, directｏｒof 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 fｏｒthousands ｏｒmillions 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 ｏｒsulphur dioxide emissions.The cause of the extinction of dinosaurs____.【单选题】

A.than more recent ones

B.the killing efficiency fｏｒolder 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:C

答案解析:has remained controversial：-直是有争议的。把这一选项跟题干合成后生成的句子说的是：有关恐龙灭绝的原因一直是有争议的。第五段有这么一句话：…because many scientists believe it was primarily caused by the impact of an asteroid. 因为许多科学家相信恐龙的灭绝主要是由于一颗小行星的影响造成的。“许多科学家”当然不是全部。“有关恐龙灭绝的原因一直是有争议的”这个命题是可以从这句话中推断出来的。

2、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum fｏｒcancer patients to swap (变换) stories ａｎｄ　share experiences on how to cope with such a devastating disease.But Cancer Chat is a forum with a difference: it has an information safety net.This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" ｏｒscientifically unsound information.Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.ａｎｄ　Rebekah Gibbs, cancer patient ａｎｄ　star of TWs Casualty, has pledged her support fｏｒthe new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer ａｎｄ　I have had such a heart - warming response from other people going through the same thing."The idea of a Cancer Chat forum means you can share information about treatment ａｎｄ　side effects ａｎｄ　you can really open up about your feelings online in a way that can be difficult when talking to close friends ａｎｄ　family. ａｎｄ　with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients ａｎｄ　their families 6,000 pages of up - to - date information that is easy to understａｎｄ　ａｎｄ　explains a wide range of treatments fｏｒdifferent types of cancer ａｎｄ　gives details of clinical trials. There is also a UK ｄａｔａｂａｓｅ of cancer clinical trials.The award - winning website attracts around one million visitors a month ａｎｄ　Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.Fｏｒthose who do not have access to computers ａｎｄ　have questions about cancer, the charity\'s team of cancer information nurses are available during office hours to talk over patients\' concerns on the phone.The word "charity" in the last line but one refers to ______. 【单选题】

A.Cancer Chat

B.CancerHelp UK

C.TWs Casualty

D.Cancer Research UK

正确答案:D

答案解析:本题有一定难度，需要认真吃透原文句意，找出判断依据。通读文章最后几段可以发现，the charity指的是慈善机构Cancer Research UK，答案是D。

3、They say Ireland\'s the BestIrelａｎｄ　is the best place in the world to live in fｏｒ2005, according to a life quality ranking that appeared in Britain\'s Economist magazine last week.The ambitious attempt to compare happiness levels around the world is based on the principle that wealth is not the only measure of human satisfaction ａｎｄ　well-being.The index of 111 countries uses data on incomes, health, unemployment, climate, political stability, job security, gender equality as well as what the magazine calls "freedom, family ａｎｄ　community life".Despite the bad weather, troubled health service, traffic congestion (拥挤), gender inequality, ａｎｄ　the high cost of living, Irelａｎｄ　scored an impressive 8.33 points out of 10.That put it well ahead of second-place Switzerland, which managed 8.07. Zimbabwe, troubled by political insecurity ａｎｄ　hunger, is rated the gloomiest (最差的) , picking up only 3.89 points."Although rising incomes ａｎｄ　increased individual choices are highly valued, " the report said, "some of the factors associated with modernization such as the breakdown in traditional institutions ａｎｄ　family values in part take away from a positive impact."Irelａｎｄ　wins because it successfully combines the most desirable elements of the new with the preservation of certain warm elements of the old, such as stable family ａｎｄ　community life. "The magazine admitted measuring quality of life is not a straightforward thing to do, ａｎｄ　that its findings would have their critics.No. 2 on the list is Switzerland. The other nations in the top 10 are Norway, Luxembourg, Sweden, Australia, Iceland, Italy, Denmark ａｎｄ　Spain.The UK is positioned at No. 29, a much lower position chiefly because of the social ａｎｄ　family breakdown recorded in official statistics. The US, which has the second highest per capita GDP after Luxembourg, took the 13th place in the survey. China was in the lower half the league at 60th.Irelａｎｄ　is positioned at NO. 1 because it combines the most desirable elements of the new withSome good elements of the old.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:问题句说“爱尔兰位居第一，因为它把新时期里最理想的因素和过去的一些好的东西融合在一起。”利用题干中出现的特征词No. 1作为答案线索，同时关注问题句中出现的修饰结构“the most desirable (elements)/最理想的”和“some good (elements)/一些好的”，这样找到答案相关句：这个句子很可能就是直接答案相关句，该句说“爱尔兰获胜了，因为它成功地把新时期最理想的因素和对过去某些温暖的东西（如稳定的家庭和社会生活）的保护结合了起来。”从这个句意上看“温暖的东西”就是“好的东西”，所以现在只需要确认“Irelａｎｄ　wins”就是指“爱尔兰位居第一”。在前文中我们看到“爱尔兰获得的分数给人留下了深刻的印象”，接着看到“这使它远远高于第2名瑞士”，判断原文中说的“Irelａｎｄ　wins”就是指“爱尔兰位居第一”，问题句的说法正确。

4、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits ａｎｄ　daytime functioning, ａｎｄ　found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - authｏｒDaniet J. Taylｏｒsaid in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylｏｒsaid.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) ａｎｄ　a decline in college students\' academic performance.The study included 64 psychology, nursing ａｎｄ　medical students, average age 27. 4 years, who were divided into two groups—low GPAs ａｎｄ　high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks ｏｒtwitches (痉挛) at night, 65.6 percent reported waking at night ａｎｄ　having trouble falling back to sleep, ａｎｄ　72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study authｏｒDr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."In the second study, students with low GPAs did NOT complain of ______.【单选题】

A.having trouble falling asleep

B.waking at night ａｎｄ　having trouble falling back to sleep

C.having difficulty concentrating during the day

D.being kicked in the leg at night

正确答案:D

答案解析:本题难度不大，答案依据比较明显，答案依据是文章倒数第二段，本段谈到了成绩较低的学生中有53. 1%的人晚上会踢腿或痉挛，但没有提到腿被踢，答案是D。

5、Happy Marriage, Happy HeartHappily married people have lower blood pressure than unhappily married people ｏｒsingles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit fｏｒsingles ｏｒunhappily 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 authｏｒJulianne 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 fｏｒ24 hours. The monitors 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 ____ in everyday life. Getting one ｏｒtwo 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 doctｏｒvisits. People in happy marriages also have a source of emotional support, she said. 【单选题】

A.take

B.do

C.make

D.want

正确答案:B

答案解析:本题难度不大，考查词义辨析。文章此处是说“……不管测试者每天都做什么”，很明显，要用动词do，答案是B。
