1、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to set aside more than 8 hours a night. He added that "it might be a good idea" for people who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall hack to sleep, and having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. One survey showed that people who habitually each night have a higher risk of dying____. 【单选题】

A.fall asleep again

B. become more energetic the following day

C.sleep less than 10 hours

D.confirm those serious consequences

E.suffer sleep problems

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. Paragraph 4____ 【单选题】

A.Killing Power of Ancient Volcanic Eruptions

B.Association of Mass Extinction with Volcanic Eruption

C.Calculation of the Killing Power of Older Eruptions

D.A Mass Extinction

E.Volcanic Eruptions That Caused No Mass Extinction

F.ccounting for the Killing Power of Older Eruptions

正确答案:D

答案解析:A mass extinction意为“一次大量的生物灭绝”。文章的第一句话是这么说的：Volcanoes were more destructive in ancient history. 火山在远古更具毁灭性。这是文章的基本论点或基本假设。假设是需要证明的。第二、三段其实都是在证明这一基本假设。第三段还有这样一句话： older eruptions were at least 10 times as effective at wiping out life as their more recant rivals. 这个命题虽然可用来支持文章的基本假设，但是它本身也需要证明。第四段讲的是二叠纪生物灭绝，这是发生在远古的大规模的生物灭绝。这是一个证据，因此D是正确的。

5、Cars Are Good for the Environment，HonestBritain\'s motor industry is planning a major publicity campaign to counter what it sees as an official anti-car bias and to improve the environmental image of the cars, according to documents leaked to the pressure group, Friends of the Earth (FOE). The five-year campaign could cost up to ￡12 million.The internal document which was produced last month by the Society of Motor Manufacturers and Traders, says that the "ultimate objective of the campaign must be to protect the long-term commercial freedom of the motor industry and the lifestyle freedom of car users". The campaign will highlight the motor industry\'s efforts to reduce emissions of carbon dioxide. European car manufacturers have already agreed with the European Com mission to reduce CO2 emissions from new cars by 25 percent to target of 140 grams per kilometer by 2008. However, the document also reveals that the industry is someway from meeting the target. ____To help control these emissions, the government has proposed replacing the flat rate annual tax on cars with a tax related to engine size so that owners of large gas-guzzler would pay more than owners of small cars. But the motor industry opposes taxes on persons owning cars preferring taxes on use.Richard Barnet, the society\'s media manager, says: "We will work with the government to practice a practical system. " But Ian Willmore of FOE says the industry “may pose as partners of the government, but its real intention is to frustrate serious attempts to reduce traffic levels”.【单选题】

6、They say Ireland\'s the BestIreland is the best place in the world to live in for 2005, 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.To measure life quality is easy.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:问题句说“衡量生活质量很容易”。相关句说“该杂志承认衡量生活质量不是一件直截了当的事情，承认杂志上的数据将可能会受到批评。”显然，该句内容表明“衡量生活质量不是一件容易的事情”，问题句的说法“错误”。

8、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed or sofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be upset when their parents left, and so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed and her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professor of nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics and psychology as to the degree women should spend with children in the outside world and the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upset and inconsolable (无法安慰的) for hours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope ____ mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone and depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive and general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the door of the hospital ward.""As a result of her work, parents are now recognized as partners in care and are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' and children\'s experience of care." 【单选题】

A.unless

B.that

C.because

D.whether

正确答案:B

答案解析:本题有一定难度，考查同位语从句引导词that的用法，此处只能用that引导同位语从句，that表示对先行词hope进行解释说明，答案是B。

9、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States and the United Kingdom can expect to live to about 74. Women to about 80, and these ages are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest ____ of the time. In the early 20th century, these were the acute and oftenhighly infectious diseases such as smallpox. Many children died very young from these diseases and others, and the weak and elderly were always at risk.In the developed world these diseases are far less deadly today, and in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation and hygiene, the discovery and use of antibiotics, which make bacterial diseases much less dangerous, and vaccinations against common diseases. In addition , people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better and warmer housing, and better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease and strokes, and those spread by viruses, such as influenza and AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease and illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】
