1、15 Million Americans Suffer from Social Anxiety DisorderSocial anxiety disｏｒｃｅｒprevents some 15 million Americans from leading normal social ａｎｄ　romantic lives, a new survey finds.The disｏｒｃｅｒleaves many isolated, ashamed ａｎｄ　often misdiagnosed. Thirty-six percent of those with social anxiety disｏｒｃｅｒhave symptoms fｏｒ10 years ｏｒmore before seeking help, the Anxiety Disorders Association of America reports."Social anxiety disｏｒｃｅｒis when somebody has an intense, persistent ａｎｄ　irrational fear of social ｏｒperformance situations," Jerilyn Ross, the association\'s president ａｎｄ　CEO, said during a teleconference Wednesday."The condition causes people to avoid common, everyday situations ａｎｄ　even other people fｏｒfear of being judged ｏｒcriticized ｏｒhumiliated ｏｒembarrassing themselves," Ross said.Social anxiety disｏｒｃｅｒcan interfere with daily routines ａｎｄ　job performance, Ross noted. "It also makes it very difficult fｏｒpeople to develop friends ａｎｄ　romantic partnerships," she said.People with this disｏｒｃｅｒrecognize their fear is excessive ａｎｄ　irrational, Ross noted. "But they feel powerless to do anything about it," she said.Social anxiety disｏｒｃｅｒcan start in the early teens, Dr. Mark H. Pollack, directｏｒof the Center fｏｒAnxiety ａｎｄ　Traumatic Stress Disorders ａｎｄ　a professｏｒof psychiatry at Harvard Medical School, said during the teleconference."This is a disｏｒｃｅｒthat starts affecting people early on," Pollack said. "The typical age of onｓｅｔis early adolescence, age 12 ｏｒ13, ａｎｄ　many individuals report a history of anxiety dating back to earlier childhood."The disｏｒｃｅｒalso has physical symptoms, including heart palpitations, feelings that their throat will close up, sweating, blushing, faintness, trembling ａｎｄ　stammering, Ross said.Among people with the disorder, 75 percent said the condition affected their ability to do normal activities. In addition, 69 percent said they didn\'t want people to think they were crazy, ａｎｄ　58 percent said they were embarrassed by their condition, Ross said.However, when the condition is diagnosed ａｎｄ　treated, many reported improvement in their lives.

A.heart palpitations

B.sore throat

C.sweating

D.blushing

正确答案:B

答案解析:第一、三、四项在短文的倒数第三段中都有提及，第二项是错误的，因为短文说的是“一种嗓子被堵塞的感觉”，而不是sore throat，即“嗓子痛”。

2、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.Courtillot rejects____.【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:D

答案解析:Wignall\'s calculations as acceptable合成后的句子是：Courtillot rejects Wignall\'s calculations as acceptable. Courtillot拒绝接受Wignall的计算。答案可以从最后两段中找到。

4、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 ____ 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 spread 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.makes

B.causes

C.make

D.from

正确答案:C

答案解析:注意这里的which不是非限制定语从句中指代前面一句话的作用，而是指代前面两项内容：卫生的改善和抗生素的发明使用，所以which后的动词不用三单形式。cause没有这样的语法搭配。

5、Nurse! I Want My MummyWhen a child is ill in hospital, a parent\'s first reaction is to be with them.Most hospitals now allow parents to sleep overnight with their child, providing a bed ｏｒsofa on the ward.But until the 1970s this practice was not only frowned upon (不赞同) — it was actively discouraged. Staff worried that the children would be ____ when their parents left, ａｎｄ　so there was a blanket (通用的) ban.A concerned nurse, Pamela Hawthorn, disagreed ａｎｄ　her study "Nurse, I want my mummy!" published in 1974, changed the face "paediatric (儿科的) nursing.Martin Johnson, a professｏｒof nursing at the University of Salford, said that the work of nurses like Pamela had changed the face of patient care."Pamela\'s study was done against the background of a lively debate in paediatrics ａｎｄ　psychology as to the degree women should spend with children in the outside world ａｎｄ　the degree to which they should be allowed to visit children in hospital.""The idea was that if mum came to visita small child in hospital the child would be upｓｅｔａｎｄ　inconsolable (无法安慰的) fｏｒhours. ""Yet the nurse noticed that if mum did not come at all the child stayed in a relatively stable state but they might be depressed. ""Of course we know now that they had almost given up hope that mum was ever coming back.""To avoid a little bit of pain they said that no one should visit.""But children were alone ａｎｄ　depressed, so Hawthorn said parents should be allowed to visit."Dr. Peter Carter, chief executive ａｎｄ　general secretary of the Royal College of Nursing, said her work had been seminal (开创性的)."Her research put an end to the days when parents handed their children over to strangers at the doｏｒof the hospital ward.""As a result of her work, parents are now recognized as partners in care ａｎｄ　are afforded the opportunity to stay with their children while they are in hospital, which has dramatically improved both parents\' ａｎｄ　children\'s experience of care." 【单选题】

A.hungry

B.upset

C.surprised

D.happy

正确答案:B

答案解析:本题难度不大，考查词义辨析，文章此处是说“工作人员担心孩子们在父母离开后会不安”，upset指“不安”，答案是B。
