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. " According to Krom, Egypt\'s Old Kingdom fell ____.【单选题】

A.immediately after a period of drought

B. immediately after a period of flood

C.just before a drought struck

D.just before a flood struck

正确答案:A

答案解析:A说的是：就在一个时期的干旱之后。第五段有这么一个句子：… one of these periods immediately predates the fall of the Egypt\'s Old Kingdom. 其中的一个时期…就发生在古埃及王国毁灭之前。可以看出，A应该是正确的答案。B：就在一个时期的水灾之后。C：就在遇到一次旱灾之前。D：就在遇到一次水灾之前。

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、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 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.Obesity ａｎｄ　alcohol consumption may also lead to some other diseases.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:C

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，答案依据在文章最后一段这一句：The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity ａｎｄ　alcohol consumption.谈到乳腺癌确诊率上升和肥胖、过度饮酒有关，但并没有提及肥胖和过量饮酒是否会引发其他疾病，因此本题未提及，答案是C。

4、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 go of such a potential weapon. Undoubtedly several nations still have a few vials. ____ 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】

A.And

B.While

C.Whereas

D.Although

正确答案:A

答案解析:上一句句末的标点符号表明本句是一个独立的句子。只有and可用于一个独立的句子，其他选项都不可以。

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 do 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 ____ 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】
