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" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.4 The Permian extinction, for example, 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, director of 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 for thousands or millions 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 or sulphur dioxide emissions.The cause of the extinction of dinosaurs____.【单选题】

A.than more recent ones

B.the killing efficiency for older 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:C

答案解析:has remained controversial：-直是有争议的。把这一选项跟题干合成后生成的句子说的是：有关恐龙灭绝的原因一直是有争议的。第五段有这么一句话：…because many scientists believe it was primarily caused by the impact of an asteroid. 因为许多科学家相信恐龙的灭绝主要是由于一颗小行星的影响造成的。“许多科学家”当然不是全部。“有关恐龙灭绝的原因一直是有争议的”这个命题是可以从这句话中推断出来的。

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 for development, people with intellectual disability have much greater potential for acquiring skills and for participation in community life than previously had been thought possible.In many western societies, five categories of intellectual disability have traditionally been used in order to indicate the perceived degree of difficulty an individual has with learning. All five may occur in either children, adolescent or adult, and show as mild, moderate, severe, profound or multiple intellectual disability.For the 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 labor during childbirth; brain damage before birth due to factors such as rubella (风疹), drug or diet-related problems; damage after birth due to illnesses such as encephalitis(脑膜炎) or accident; hereditary defects in the genes; abnormal chromosome count resulting in, for example, 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 for replies 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。

C.they also have feelings

D.an assessment of a person\'s performance in a variety of tests

4、Cancer1. 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(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 or order.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, or exposure to carcinogens (致症物) in the workplace or in the environment. Some gene alterations are inherited.3. 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, 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 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.Paragraph 4 ______【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:B

答案解析:本题有一定难度，但主要的段落主旨句是文章第四段的第一句，谈到癌症并不总是意味着疼痛，病人的疼痛程度取决于多种因素，如癌症类型，患病程度，病人对疼痛的忍受力。回来看选项，B项Does cancer always cause pain?简单概括了本段意思，是答案。
