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. " Which of the following statements is true? 【单选题】

A.The White Nile is the trunk of the River Nile.

B.The White Nile is the trunk of the Blue Nile.

C.The White Nile is a branch of the Blue Nile.

D.The White Nile ａｎｄ　the Blue Nile are branches of the River Nile.

正确答案:D

答案解析: D说的是：青尼罗河和白尼罗河是尼罗河的支流。第四段中的最后一句话是这么说的：… worked out what proportion of sediment came from each branch of the river. 这里的“河”是指“尼罗河”，“每条支流”是指上文所说的“青尼罗河”和“白尼罗河”。因此，D是正确的答案。A：白尼罗河是尼罗河的干流。B：白尼罗河是青尼罗河的干流。C:白尼罗河是青尼罗河的支流。显然，这些都不是答案。

2、CancerCancer 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. 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.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 radiation from the sun, ｏｒexposure to carcinogens (致癌物) in the workplace ｏｒin the environment. Some gene alterations are inherited.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, weighing the likely benefits of killing cancer cells ａｎｄ　the risks of possible side effects.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.Gene alterations may be caused by____.【单选题】

A.prescription medicines

B.control ｏｒorder

C.tolerance fｏｒpain

D.various factors

E.normal genes

F.different genes side effects

正确答案:D

答案解析:根据题干线索词Gene alterations定位原文至第二段第二句“Certain lifestyle ａｎｄ　environmental factors can change some normal genes into genes that allow the growth of cancer”，题干中的alterations与句中的change虽然词性不同，但意思相同。题干将该句由主动态变为被动态，由此推断，句中画线部分即为题干所需添加成分。而D选项various factors是对该部分的同义改写，故为正确答案。

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.Visual memory may be used when we read a story.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:这句话仍然是在说视觉记忆，所以还应该在刚才的段落里找相关的句子加以判断，意思是：有些人有如此强大的视觉记忆以至于他们能够准确地记住他们所看见的东西，如：能够将所看过的书形成一幅完整的图画。这就说明当我们阅读书籍时人们的视觉记忆的确很重要，能够被人们加以利用。

4、Importance of Children\'s Oral HealthFebruary is National Children\'s Dental(牙齿的) Health Month, but in children good oral(口部的) care is critical every day. The first comprehensive study on the nation\'s oral health, released recently by the Office of the U. S. Surgeon General, calls dental ａｎｄ　oral diseases a "silent epidemic (流行病)", even in children. The report states that more than 51 million school hours are lost each year to dental - related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children.To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children ａｎｄ　parents about the prevention of dental diseases in children."This is important because oral problems can impact self - esteem fｏｒchildren ａｎｄ　lead to problems of eating, speaking ａｎｄ　attending to learning," said Michael McGuire, president of the AAP.Common dental problems seen in children are cavities (龋洞) ａｎｄ　gingivitis (龈炎), which are found in the majority of U. S. children. "When these problems are not caught early ａｎｄ　treated, they can develop into more severe problems ａｎｄ　cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems."In the Rio Grande Valley in Texas, aｇｒｏｕｐof more than 120 dentists(牙医) volunteers to deliver dental care to thousands of low - income children each year with its Mobile Dental Unit that travels from school to school."According to the Surgeon General\'s Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don\'t see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, ａｎｄ　parents miss the opportunity to learn how to promote good oral habits in their children.Some children have never seen a dentist before starting school.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，带者题干信息词回文章定位，答案依据在文章最后一段第一句：…about 37 per cent of children have not had a dental visit before start ing school，谈到约37%的孩子上小学前从没看过牙医，所以本题和原文句意相符，答案是A。
