1、Blasts from the Past1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease.2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions ａｎｄ　mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300. million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do.3 Wignall calculated the "killing efficiency" fｏｒthese volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size fｏｒsize, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.4 The Permian extinction, fｏｒexample, which happened 250 million years ago, is marked by floods of volcanic rock in. Siberia that cover an area roughly the size of western Europe, Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide, The global warming that followed wiped out 8 per cent of all marine genera at the time, ａｎｄ　it took 5 million years far tire planet to recover.5 Yet 60 million years ago in the late Palaeocene there was another huge amount of volcanic activity ａｎｄ　global-warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years, "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up ａｎｄ　exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere.7 Vincent Courtillot, directｏｒof the Paris Geophysical Institute in France, says that Wignall\'s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. ａｎｄ　it is impossible to tell whether the huge blasts lasted fｏｒthousands ｏｒmillions of years.8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, ａｎｄ　that lava volume may not necessarily correspond to carbon dioxide ｏｒsulphur dioxide emissions.Older eruptions were more devastating____.【单选题】

A.than more recent ones

B.the killing efficiency fｏｒolder eruptions

C.has remained controversial

D.Wignall\'s calculations as acceptable

E.has been mown to us all

F.his ideas

正确答案:A

答案解析:more recent ones较后来的火山爆发。填入后生成的句子不仅在语法上是正确的并且跟文章第一句话的意思差不多。

2、Intellectual DisabilityPeople with intellectual disability form one of the largest single disability groups in a community. Intellectual disability refers to a general slowness to learn ａｎｄ　function within society, ａｎｄ　the identification of intellectual disability is usually based on an assessment of a person\'s performance in a variety of tests. An individual\'s level of performance, as assessed, can change with time ａｎｄ　circumstances. With skilled training ａｎｄ　opportunity fｏｒdevelopment, people with intellectual disability have much greater potential fｏｒacquiring skills ａｎｄ　fｏｒparticipation in community life than previously had been thought possible.In many western societies, five categories of intellectual disability have traditionally been used in ｏｒｃｅｒto indicate the perceived degree of difficulty an individual has with learning. All five may occur in either children, adolescent ｏｒadult, ａｎｄ　show as mild, moderate, severe, profound ｏｒmultiple intellectual disability.Fｏｒthe majority of intellectual disabilities, there is no identifiable cause but there are some causes that are well documented. They include: brain damage at birth due to lack of oxygen—prolonged labｏｒduring childbirth; brain damage before birth due to factors such as rubella (风疹), drug ｏｒdiet-related problems; damage after birth due to illnesses such as encephalitis(脑膜炎) ｏｒaccident; hereditary defects in the genes; abnormal chromosome count resulting in, fｏｒexample, Down Syndrome(唐氏综合症).Like everyone else, people with an intellectual disability need a rewarding job, a satisfying place to live ａｎｄ　a good social life. But they may need extra support to achieve these things. Good support services are based on the principle of normalization—which means enabling people to be part of the community like everyone else,With the introduction of the intellectually disabled into communities, there is a need to promote awareness of communication. Although many people may have little experience in talking with an intellectually disabled person, there are common guidelines that can simplify the interaction. Firstly, it is useful to remember that people with disabilities have feelings. Speaking in the same friendly manner as you would to anyone else is also recommended. Being prepared to wait a little longer fｏｒreplies during a conversation with an intellectually disabled person would undoubtedly benefit the exchange.Paragraph 2____.【单选题】

A.What do people with an intellectual disability need

B.What is intellectual disability

C.How do people with an intellectual disability talk

D.What are the forms of intellectual disability

E.What causes intellectual disability

F.How do you talk to a person with an intellectual disability

正确答案:D

答案解析:第二段主题句为第一句，其意思是：在许多西方国家，传统意义上的智力障碍会被分为五个范畴来表示智力障碍者学习能力的水平。由此推断，该段回答了D选项“What are the forms of intellectual disability?”所提问题，故D为正确答案。

3、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.Paragraph 2 ______【单选题】

A.How is cancer treated?

B.Does cancer always cause pain?

C.Can cancer be prevented?

D.What is cancer?

E.How common is cancer?

F.What causes cancer?

正确答案:F

答案解析:本题难度也不大，段落主旨句比较明显，是文章第二段的第一句，谈到科学家已查明癌症是由基因变化引起的，基因通常控制着细胞的生长和死亡，回来看选项，F项What causes cancer?简单概括了本段意思，是答案。

4、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.A lot of research is being done to find out ____.【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:F

答案解析:人们正在进行大量的研究来发现导致帕金森综合征的原因。根据第二段前三句话及后面提到的aging ａｎｄ　the poisons in environment等可推断应选F。
