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 go 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, ____ no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests 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.since

B.for

C.because

D.of

正确答案:B

答案解析:整个句子说的是，美、俄“官方”的最后的活病毒储备由于不能带来明显的好处而引起大家对这两个国家的不信任。no?obvious?gain是名词短语。for可跟名词短语，表示原因。because不跟名词短语。since可跟名词短语，但跟表示时间的名词短语。of可跟名词短语，但常表示“所属”关系。故B为正确答案。

2、The Process of AgeingAt the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is the least. Earlier, we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigor resistance which, though imperceptible (察觉不出的) at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us This decline in vigor with the passing of time is called ageing. If we escape wars, accidents and diseases, we shall eventually "die of old age", ____. Some of us will die sooner, a few will live longer. But there is a virtual limit on how long we can hope to remain alive, however lucky and robust we are.Normal people tend to forget this process until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigor with time was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. "They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do; and mechanical systems like a wound watch, or the sun, do in fact run out of energy. But these are not analogous to what happens when man ages. A run-down watch is still a watch and can be rewound. And old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself it does not consist of living parts, only of metal, which wears away by friction (摩擦). We could, at one time tune, repair ourselves well enough, at least to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power.an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 of the survivors to be reduced by half again.【单选题】

A. Some old people are oppressed by the fear of death

B. an illness which at twelve would knock us over, at eighty can knock us out, and into our grave

C. and mechanical systems like a wound watch, or the sun, do in fact run out of energy

D.This decline in vigor with the passing of time is called ageing

E.And old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending

F.and this happens at a rate which differs little from person to person

正确答案:F

答案解析:空白处的前一句说，如果能逃脱战争、事故和疾病，最终我们都会死于衰老。空白处的后一句说，有的人死得早些，有的人活得比较长。六个选项中只有F能够同时与上下两句连接。所选句中的this指前一句中的die of old age。

3、CancerCancer is a group of 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 or tumor. 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 or order.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, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, and biological therapy. The doctor may use one method or a 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 for cancer 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 for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.Gene alterations may be caused by____.【单选题】

A.prescription medicines

B.control or order

C.tolerance for pain

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。

A.will?be

B.would?be

C.is

D.are

正确答案:C

答案解析:本句是个条件句。从句中动词一般用现在时表示“未来”。这就排除了will?be和would?be。virus是单数，因此D也不正确。故C为正确答案。

5、What are my chances of promotion if I stay here?【单选题】

A.retirement

B.advertisement

C.advancement

D.replacement

正确答案:C

答案解析:如果我还待在这干，我有升职的机会吗？promotion指“提升，晋级”，和advancement的引申意义“晋升”是同义词，A项指“退休”，B项指“广告”，D项指“代替”，三项的干扰性不强。本题考查的是advancement的引申意义。

6、Her father was a quiet man with graceful manners.【单选题】

A.polite

B.similar

C.usual

D.bad

正确答案:A

答案解析:她的父亲温文尔雅，是一个安静的人。本题难度不大，是送分题。graceful是“典雅的，文雅的”，和polite“礼貌的”意思相近，其他三项都是常用词，和答案意义差异大，干扰性不强

7、Smart Window Windows not only let light in to cut down an electricity use for lighting, but the light coming through the window also provides heat. However, windows are not something people typically associate with being a cutting edge technology. Researchers are now working on new technologies that enable a window to quickly change from clear to dark and anywhere in between with a flip of a switch. "It took us a long time to figure out what a window really is," says Claes Granqvist. He\'s a professor of solid-state physics at Uppsala University in Sweden. "It\'s contact with the outside world. You have to have visual contact with the surrounding world to feel well. " So, windows and natural light are important for improving the way people feel when they\'re stuck indoors. Yet, windows are the weak link in a building when it comes to energy and temperature control. In the winter, cold air leaks in. When it\'s hot and sunny, sunlight streams in. All of this sunlight carries lots of heat and energy. And all of this extra heat forces people to turn on their air conditioners. Producing blasts of cold air, which can feel so refreshing, actually suck up enormous amounts of electricity in buildings around the world. Windows have been a major focus of energy research for a long time. Over the years, scientists have come up with a variety of strategies for coating, glazing, and layering windows to make them more energy efficient. Smart windows go a step further. They use chromogenic technologies which involve changes of color. Electrochromic windows use electricity to change color. For example, a sheet of glass coated with thin layers of chemical compound such as tungsten oxide works a bit like a battery. Tungsten oxide is clear when an electric charge is applied and dark when the charge is removed, that is, when the amount of voltage is decreased, the window darkens until it\'s completely dark after all electricity is taken away. So applying a voltage determines whether the window looks clear or dark. One important feature that makes a smart window so smart is that it has a sort of "memory. " All it takes is a small jolt of voltage to turn the window from one state to the other. Then, it stays that way. Transitions take anywhere from 10 seconds to a few minutes, depending on the size of the window. The development of smart windows could mean that massive air conditioning systems may no longer need. "In the future," Granqvist says, "our buildings may look different. To make electrochromic windows change color, what is applied to the window glass? 【单选题】

A. Electricity.

B.Tungsten oxide.

C.A battery.

D.A voltage.

正确答案:B

答案解析:第五段第二句提供了答案。a sheet of glass coated with thin layers of chemical compound such as tungsten oxide中的coated是“涂上一层薄薄的……”的意思。

8、TV Games Shows One of the most fascinating things about television is the size of the audience. A novel can be on the "best sellers" list with a sale of fewer than 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well known overnight. This is the principle behind "quiz" or "game" shows, which put ordinary people on TV to play a game for the prize and money. A quiz show can make anyone a star, and it can give away thousands of dollars just for fun. But all of this money can create problems. For instance, in the 1950s, quiz shows were very popular in the U. S. and almost everyone watched them. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show\'s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn\'t like the person who won the game, they turned the show off. Based on his story, a movie under the title " Quiz Show" is on 40 years later. Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren\'t taken as seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions. Winners of present-day TV shows no longer get money from the shows. 【单选题】

A. Right

B. Wrong

C.Not mentioned

正确答案:B

答案解析:答案查找的线索词：get money from the shows（从节目中得到钱）。从第三段开始查找，不难在第三段的最后一句中找到与get money from the shows语义相近的词：win money. 对照原句和问题句，原句说人们仍然可以赢得钱，所以问题句的大意与原句不符。

9、Parkinson\'s Disease1. Parkinson\'s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine(多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson\'s, these nerve cells break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.2. No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson\'s disease in some people. But so far, there is not enough proof to show that it is always inherited.3. Tremor (颤抖) may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure for Parkinson\'s disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You may not even need treatment if your symptoms are not obvious. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.A person with Parkinson-s has to learn to live with the disease, ______.【单选题】

A.if there isn’t enough dopamine in your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed or blank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:C

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第四段前两句，谈到帕金森病还不能彻底治愈，但有几种药物可以控制症状使其变得容易忍受，回来看选项，C项和原文句意相符，是答案。

10、He made a great show of reluctance, but finally accepted my offer. 【单选题】
