1、Smallpox virusIt\'s now a fair bet that we will never see the total extinction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it—one in the US ａｎｄ　one in Russia. If smallpox had truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let ____ of such a potential weapon. Undoubtedly several nations still have a few vials. ａｎｄ　the last “official” stocks of live virus bred mistrust of the US ａｎｄ　Russia, fｏｒno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fｏｒtests on new treatments ａｎｄ　vaccines. So one again there\'s a good reason to keep the virus—just in case the disease puts in a reappearance.How do we deal with the mistrust of the US ａｎｄ　Russia? Simple. Keep the virus under international auspices in a well-guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn\'t mean the idea is wrong. If the virus is useful, then let\'s make it the servant of all humanity—not just a part of it.【单选题】

3、The Need to RememberSome people say they have no memory at all: "I just can\'t remember a thing!" But of course we all have a memory. Our memory tells us who we are. Our memory helps U. S. to make use in the present of what we have learnt in the past.In fact we have different types of memory. Fｏｒexample, our visual memory helps us recall facts ａｎｄ　places. Some people have such a strong visual memory that they can remember exactly what they have seen, fｏｒexample, pages of a book, as a complete picture.Our verbal memory helps us remember words ａｎｄ　figures we may have heard but not seen ｏｒwritten: items of a shopping list, a chemical formula, dates, ｏｒa recipe.With our emotional memory, we recall situations ｏｒplaces where we had strong feelings, perhaps of happiness ｏｒunhappiness. We also have special memories fｏｒsmell, taste, touch ａｎｄ　sound, ａｎｄ　fｏｒperforming physical movements.We have two ways of storing any of these memories. Our short-term memory stores items fｏｒup to thirty seconds-enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items fｏｒa lifetime. Older people in fact have a much biter long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance of when they were very young.Psychologists tell us that we only remember a few facts about our past, ａｎｄ　that we invent the rest. It is as though we remember only the outline ofa story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past, ｏｒmaybe victims needing sympathy.Emotional memory is used when we perform physical movements.【单选题】

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" 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. Paragraph 3____ 【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 fｏｒthe Killing Power of Older Eruptions

正确答案:C

答案解析:第三段的第一句话是这么说的：Wignall calculated the“killing efficiency”fｏｒthese valcanoes wignall计算了这些火山的“灭种效率”。killing power与killing efficiency意思差不多。killing power：灭种力。

5、Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year fｏｒthe first time since records began.The Cancer Research UK data showed that 11,990 women died in the UK in 2007.The previous lowest figure had been recorded in 1971-the year records began after which it rose steadily year by year until the late 1980s.ProfessｏｒPeter Johnson, Cancer Research UK\'s chief clinician said, "It\'s incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often. "Research has played a crucial role in this progress leading to improved treatments ａｎｄ　better management fｏｒwomen with the disease."The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed. "Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years.The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 ａｎｄ　400 deaths each year until 2004.There was a slight rise in 2005 ａｎｄ　then two years of falls.Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer ａｎｄ　highlights the impact of improved treatments, breast screening ａｎｄ　awareness of the disease. " ."However, this is still too many women ａｎｄ　incidence of the disease is increasing year by year."The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity（肥胖） ａｎｄ　alcohol consumption.Fewer women died from breast canc\'er in the UK in 2005 than in 2004.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:B

答案解析:2005年死于乳腺癌的患者少于2004年。根据倒数第四段中：There was a slight rise in2005，可以推断该论断是错误的。
