1、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. 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 fｏｒsure what makes these nerve cells break down. But scientists are doing a lot of research to look fｏｒthe 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 Tremｏｒmay be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. More importantly, not everyone with a tremｏｒhas Parkinson\'s disease. Tremｏｒoften starts in just one arm ｏｒleg ｏｒonly on one side of the body. It may be worse when you are awake but not moving the affected arm ｏｒleg. It may get better when you move the limb ｏｒyou are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing ｏｒconstipation. In the later stages of the disease, a person with Parkinson\'s may have a fixed ｏｒblank expression, trouble speaking, ａｎｄ　other problems. Some people also have a decrease in mental skills (dementia).4 At this time, there is no cure fｏｒParkinson\'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 mild. Your doctｏｒmay wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctｏｒwill adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.You\'ll find it hard to move the way you want to ____.【单选题】

A.if there isn\'t enough dopamine your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed ｏｒblank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:A

答案解析:如果你的体内没有足够多的多巴胺，那么你会发现活动起来有困难。根据第一段最后一句： Then you no longer have enough dopamine, ａｎｄ　you have trouble moving the way you want to. 因此选A。

2、Smart Window Windows not only let light in to cut down an electricity use fｏｒlighting, 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 professｏｒof 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 fｏｒimproving 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 majｏｒfocus of energy research fｏｒa long time. Over the years, scientists have come up with a variety of strategies fｏｒcoating, 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. Fｏｒexample, 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 ｏｒdark. 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。

3、Life Expectancy in the Last Hundred YearsA hundred years ago, life expectancy in developed countries was about 47 in the early 21st century, men in the United States ａｎｄ　the United Kingdom can expect to live to about 74. Women to about 80, ａｎｄ　these ages are rising all the time. What has brought about these changes? When we look at the life span of people 100 years ago, we need to look at the greatest killers of the time. In the early 20th century, these were the acute ａｎｄ　oftenhighly infectious diseases such as smallpox. Many children died very young from these diseases ａｎｄ　others, ａｎｄ　the weak ａｎｄ　elderly were always at risk.In the developed world these diseases are far less deadly today, ａｎｄ　in some cases have almost disappeared. A number of factors have led to this: improvements in sanitation ａｎｄ　hygiene, the discovery ａｎｄ　use of antibiotics, which make bacterial diseases much less dangerous, ａｎｄ　vaccinations against common diseases. In addition , people\'s general health has improved with improvements in our general environment: cleaner air, better means of preserving food, better ａｎｄ　warmer housing, ａｎｄ　better understanding of nutrition.Genetically, we should all be able to live to about 85 but while people do live longer today, there are still some big killers around that are preventing US from consistently reaching that age. The problems that affect people today are the more chronic illnesses, such as heart disease ａｎｄ　strokes, ａｎｄ　those ____ by viruses, such as influenza ａｎｄ　AIDS. Of course, cancer is a huge killer as well. In most cases these diseases affect older people, but there are worrying trends in the developed world with problems such as obesity leading to more heart disease ａｎｄ　illnesses such as diabetes at younger ages.The killers today can be classed as "lifestyle diseases", which means that it may be possible to halt their progress.【单选题】

A.spread

B.affected

C.produced

D.created

正确答案:A

答案解析:those指代流感和艾滋病等靠病毒传播的疾病，those后面的动词是过去分词作定语。spread的过去分词与原形相同。

4、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.Breast cancer is more common in the UK than in many other countries.【单选题】

A.Right

B.Wrong

C.Not mentioned

5、Online Cancer Chat with a Safety NetCancer Research UK has launched an online chat forum fｏｒcancer 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" ｏｒscientifically 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 fｏｒthe 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 fｏｒdifferent 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.Fｏｒthose 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.Cancer Chat is different from other forums chiefly in that ______.【单选题】
