1、Cancer
Cancer 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。

2、Smallpox virus
It'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 ____ 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, for 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.to?go

B.going

C.go

D.went

正确答案:C

答案解析:let后接动词原形，go符合这一原则。故C为正确答案。

5、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.
What will be the benefit if the research on smart windows turns out to be successful, according to the last paragraph?
【单选题】

A.The buildings will look different.

B.Windows can be as large as you want.

C.We may not need air conditioners any more.

D.They are less expensive than traditional windows.

正确答案:C

答案解析:被选项中出现了大量的修饰词，段落最后一段的倒数第2句是直接答案相关句，根据该句内容判断C是答案。

6、Musical Training Can Improve Communication Skills
American scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities.
Nina Kraus is a neurobiologist at Northwestern University in Illinois. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much different from learning how to speak. ____.
She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed or changed. But Professor Kranss and her team found that musical training can improve a person's brain stem activity.
The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking and a person playing a musical instrument ---- the cello.
Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech. The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. It shows the importance of musical training to children with learning disabilities. She says using music to improve listening skills could mean they hear sentences and understand facial expressions better.
【单选题】

A.Both involve different senses.

B.Nina Kraus is a neurobiologist at Northwestern University in Illinois.

C.Some disabled children attended the musical training Class.

D.It shows the importance of musical training to children with learning disabilities.

E.Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech.

F.The brain stem controls our ability to hear.

正确答案:A

答案解析:本段的第二、三句说，音乐训练和学习这两件事没有什么：很大的不同。选项A的Both involve different senses解释了为什么这么说，因为两者都涉及不同的感官，也就是上文所列举的hearing music（耳听），looking at musical notes／watching other musicians（眼看），touching an instrument（手触）等。

7、Memories
Most episodes of absent-mindedness forgetting where you left something or wondering why you just entered a room are caused by a simple lack of attention, says Schacter. "You are supposed to remember something, but you haven't encoded it deeply."
Encoding, Schacter says, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don't pay attention to what you did because you are involved in a conversation, you will probably forget that the phone is in the jacket now hanging in your wardrobe. "Your memory itself isn't failing you," says Schacter. " Rather, you didn't give your memory system the information it needed. "
Lack of interest can also lead to absent-mindedness. "A man who can recite sports statistics from 30 years ago," says Zelinski, "may not remember to drop a letter in the mailbox. " Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that.
Visual cues can help prevent absent-mindedness, says Sclnacter." ____,"he cautions. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table don't leave it in the medicine chest and write yourself a note that you keep in a pocket.
Another common episode of absent-mindedness: walking into a room and wondering why you are there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you will likely remember.

8、The Ideal Husband
Science now might be able to explain women's fascination with Brad Pitt's face and George Clooney's eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.
In the study by Daniel Kruger at the US's University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.
Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.
But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.
The study was published in the December issue of the US journal Personal Relationships.
Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible for the development of masculine facial features and other sexual characteristics. It has been found to affect the body's ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.
However, increased testosterone has also been linked to cheating and violence in relationships. So, these men ____ produce high quality offspring, but they don't always make great parents or faithful mates, Kruger says.
The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.
【单选题】

A.must

B.might

C.have to

D.should

正确答案:B

答案解析:must：必须；might：可能；have to：必须；should：应该。女人根据男人的特征选择伴侣这只是一个因素，因此下结论应该留有余地，用might是比较合适的。

9、Parkinson's Disease
1. 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 lot of research is being done to find out ______.
【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:F

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第二段的第二句和第三句，谈到科学家们正在为找到答案而进行大量的研究，研究各种可能病因，回来看选项，F项和原文句意相符，是答案。

10、Online Cancer Chat with a Safety Net
Cancer Research UK has launched an online chat forum for cancer patients to swap (变换) stories and share experiences on how to cope with such a devastating disease.
But Cancer Chat is a forum with a difference: it has an information safety net.
This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue (劣等的) "cancer cures" or scientifically unsound information.
Anyone can have access to the messages posted on Cancer Chat, but if people wish to post a message, they will need to register.
And Rebekah Gibbs, cancer patient and star of TWs Casualty, has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart - warming response from other people going through the same thing."
The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research UK monitoring the forum, people can be reassured about the quality of information being exchanged.
Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website, which is specially designed to give patients and their families 6,000 pages of up - to - date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a UK database of cancer clinical trials.
The award - winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum.
For those who do not have access to computers and have questions about cancer, the charity's team of cancer information nurses are available during office hours to talk over patients' concerns on the phone.
The word "charity" in the last line but one refers to ______. 【单选题】

A.Cancer Chat

B.CancerHelp UK

C.TWs Casualty

D.Cancer Research UK

正确答案:D

答案解析:本题有一定难度，需要认真吃透原文句意，找出判断依据。通读文章最后几段可以发现，the charity指的是慈善机构Cancer Research UK，答案是D。
