2、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same or worse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic for the Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " Which of the following factors was ultimately responsible for the fall of the civilization of ancient Egypt? 【单选题】

A.Change of climate.

B.Famine.

C.Flood.

D.Population growth.

正确答案:A

答案解析:A：气候的变化。第一段中有这样一个子句… a shift in climate… was ultimately to blame…最终须归咎于气候的变化。在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。因此A是正确的答案。B：饥荒。C：水灾。D：人口增长。

3、Acceptance of Chronic IllnessFor chronically ill patients, giving up the hope that they will get better may actually lead to more happiness, U. S. researchers suggest."Hope is an important part of happiness, but there\'s a dark side of hope. Sometimes, if hope makes people put off getting on with their life, it can get in the way of happiness," Dr. Peter A. Ubel from the University of Michigan Health System said in a university news release.He and his colleagues studied patients who\'d just had a colostomy (结肠造口术), which means their colons (结肠) were removed and they had to have bowel (肠) movements in a pouch (小袋) outside the body. At the time of the surgery, some patients were told the procedure was reversible and they\'d have a second operation in a few months to reconnect their bowels. Other patients were told the colostomy was permanent.The patients were followed for six months, and the researchers found that those without hope of regaining normal bowel function were happier than those with reversible colostomies."We think they were happier because they got on with their life. They realized the cards they were dealt, and recognized that they had no choice but to play with those cards," Ubel said. "The other group was waiting for their colostomy to be reversed. They contrasted their current life with the life they hoped to lead, and didn\'t make the best of their current situation. "The study, published in the November edition of Health Psychology, also may explain why people whose spouse dies often recover better emotionally over time than those who get divorced, the researchers said.That\'s because people whose husband or wife dies have closure (结束), while those who get divorced may still have hope for some chance of making up, they explained.What could be the message of the passage? ______【单选题】

A.Giving up hope means giving up happiness.

B.Letting go of hope sometimes is a better choice.

C.Hope is what makes people move on.

D.Hope frequently gets in the way of happiness.

正确答案:B

答案解析:本题有一定难度，需要通读全文。文章第一段实际就是全文的主旨段落，谈到，对于病人来说放下治愈希望会更幸福，第二段第一句谈到，希望有时候会有不好的一面，第四段，第五段都提到了研究者发现放下治愈希望的病人比持有希望的病人要开心，回来看选项，B项和原文句意相符，是答案。

4、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 for the 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.Professor Peter 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 for women with the disease.""The introduction of the NHS (国民保健制度) breast screening 3 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 cancer 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:本题有一定难度，关键在吃透句意。答案依据比较明显，带着题干信息词回文章定位，答案依据在文章第九段这一句：There was a slight rise in 2005 and then two years of falls．谈到2005年乳腺癌患者死亡人数有所增长，随后两年有所下降。换句话说，2005年的死亡人数比2004年多，很明显，题干和原文句意相反，所以本题错误，答案是B。

7、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 2____ 【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:B

答案解析:第二段的第一句话是这么说的：Paul Wignall from the University of Lees was investigating the link between volcanic eruptions and mass extinctions. 里兹大学的Paul Wignall正在研究火山爆发与物种大量灭绝的联系。. . . the association of mass extinctions with volcanic eruptions与the link between volcanic eruptions and mass extinctions在意思上是相同的。

10、Cooking Oil Fumes Cause TumorThe leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking, said medical experts after a fiveyear research study.Doctors announced the results yesterday with analysis on some new tendencies in lung cancer, They said patients are younger, especially women.According to the Shanghai Tumor research Institute, more local residents die of lung cancer in the city than anything else. Following breast cancer, it has the second-highest incidence rate."An unhealthy lifestyle is a very important reason for lung cancer," said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.He followed 2,276 lung cancer patients for five years. Among them, 1,433 were male.Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke, according to the report.However, more than 60 percent of women with the disease had long term, close contact with strong oil fumes from cooking and complained about irritated eyes and throat.About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women\'s bedrooms were adjacent to the kitchen.However, local women were surprised to learn cooking oil fumes could lead to cancer. Some claimed they may change food preparation methods. "Unless my family and I don\'t eat at home every day, I must stay in the kitchen to cook," said Xu Li, a 45-year-old local woman. "I know the fumes are bad for the skin, but it is the first time I heard that it can result in lung cancer. I have already started frying less. "Doctors said women\'s lung cancer had few links to personal health and physical condition, but was closely related to family cancer history, unhealthy dietary habits and weak immune systems.Other experts agreed with him."Smoking is by far the biggest cause of lung cancer for men," said Dr. Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University\'s Medical College. "It\'s true that second-hand smoke and cooking fumes are the main causes among women. "His research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.The chance of catching lung cancer is three times higher if exposed to the fume for a long time, experts said.Which of the following diseases is the most common among the local residents in Shanghai?【单选题】

A.Heart disease.

B.Breast cancer.

C.Infectious diseases.

D.Lung cancer.

正确答案:B

答案解析:细节考查题。答案参见第三段最后一句：Following breast cancer，it has the second-highest incidence rate（肺癌排在乳腺癌之后，发病率第二高）。可见最常见的疾病就是乳腺癌，故正确答案为B。
