1、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 ｏｒworse 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 fｏｒthe 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. " Why does the authｏｒmention "pyramid builders " ? 【单选题】

A.Because they once worked miracles.

B.Because they were well-built.

C.Because they were actually very weak.

D.Because even they were unable to rescue their civilization.

正确答案:D

答案解析: D：甚至是他们也不能挽救他们的文明。因此D是正确的答案。A：他们曾创造过奇迹。B:他们很强壮。C：他们其实很弱。

2、Cancer1. Cancer is aｇｒｏｕｐof many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally, cells grow ａｎｄ　divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, ａｎｄ　old cells do not die when they should. The extra cells form a mass of tissue called a growth ｏｒtumｏｒ肿瘤). Benign(良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal ａｎｄ　divide without control ｏｒorder.2. Scientists have learned that cancer is caused by changes in genes that normally control the growth ａｎｄ　death of cells. Certain lifestyle ａｎｄ　environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet(紫外线的) radiation from the sun, ｏｒexposure to carcinogens (致症物) in the workplace ｏｒin the environment. Some gene alterations are inherited.3. Cancer treatment can include surgery, radiation therapy, chemotherapy(化疗), hormone therapy, ａｎｄ　biological therapy. The doctｏｒmay use one method ｏｒa combination of methods, depending on the type ａｎｄ　location of the cancer, whether the disease has spread, the patient\'s age ａｎｄ　general health ａｎｄ　other factors. Because treatment fｏｒcancer can also damage healthy cells ａｎｄ　tissues, it often causes side effects. Patients ａｎｄ　doctors generally discuss the treatment options, weighting the likely benefits of killing cancer cells ａｎｄ　the risks of possible side effects.4. Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease ａｎｄ　the patient\'s tolerance fｏｒpain. Most pain occurs when the cancer grows ａｎｄ　presses against bones, organs, ｏｒnerves. Pain may also be a side effect of treatment. However, pain can generally be relieved ｏｒreduced with prescription medicines ｏｒover - the - counter drugs recommended by the doctor.Cancer patients may differ in their ______.【单选题】

A.side effects

B.prescription medicines

C.control ｏｒorder

D.tolerance fｏｒpain

E.various factors

F.different genes

正确答案:D

答案解析:本题有一定难度，需要认真寻找答案依据。答案依据在文章第第四段第二句话：Whether a patient has pain may depend on … ａｎｄ　the patients\' tolerance fｏｒpain，谈到病人是否感觉疼痛取决于癌症的类型，患病严重程度以及病人对疼痛的忍耐力，回来看选项，D项符合原文句意，是答案。

3、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 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 fｏｒthe 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。

4、Waste Not, Want Not1 Bob ａｎｄ　Clara Darlington, who own ａｎｄ　run a farm in the North of England, have always looked fｏｒnew ways of making money out of the produce they grow. Their SUCCESS began when they established a shop on their farm, so that people could come ａｎｄ　buy fresh vegetables directly from them.2 The business was an immediate SUCCESS, ａｎｄ　soon scored top marks in a competition ｓｅｔup by the Farm Retail Association to find the best farm shop in the country. The Association\'s inspectors found the Darling tons\' shop offered excellent service ａｎｄ　value fｏｒmoney as well as quality fruit ａｎｄ　vegetable.3 Clara Darlington is a trained chef and, in addition to a range of home-grown foods ａｎｄ　other local produce, she began offering a variety of prepared meals which she had made herself in the farmhouse kitchen. A small cafe alongside the farm shop was soon added, with everything that visitors could taste on the menu also being fｏｒsale in the shop.4 Clara admits that starting the business was expensive, ａｎｄ　she has worked very hard, but maintains that if the product is good, the public recognize this ａｎｄ　buy it. "I aim to offer the highest quality to our customers, whether they come in fｏｒa loaf of bread, ｏｒtake a whole dinner-party menu. I take it as a compliment if people take home one of my dishes to serve to their family ａｎｄ　friends ａｎｄ　get away with pretending they made it themselves. "5 So it was that the couple realized that they had a surplus of misshapen ｏｒdamaged vegetables grown on the farm which were unsuitable fｏｒselling in the shop. Clara, not wishing to see them get thrown away, decided to turn them into soup.6 The soup met with the immediate approval of customers to the shop ａｎｄ　Clara now produce different varieties. She spent much of the summer traveling up ａｎｄ　down to London by rail, doing presentations of the soups. As a result, they are now served in first-class railway restaurant cars belonging to three companies as well as being stocked by a number of high-class London stores.Instead of throwing the damaged vegetables away, the couple ____.【单选题】
