4.AEddie McKay, a once-forgotten pilot, is a subject of great interest to a group of history students in Canada.It all started when Graham Broad, a professor at the University of Western Ontario, found McKay’s name in a footnote in a book about university history. McKay was included in a list of university alumni (校友) who had served during the First World War, but his name was unfamiliar to Broad, a specialist in military history. Out of curiosity, Broad spent hours at the local archives (档案馆) in a fruitless search for information on McKay. Tired and discouraged, he finally gave up. On his way out, Broad’s glance happened to fall on an exhibiting case showing some old newspapers. His eye was drawn to an old picture of a young man in a rugby uniform. As he read the words beside the picture, he experienced a thrilling realization. “After looking for him all day, there he was, staring up at me out of the exhibiting case,” said Broad. Excited by the find, Broad asked his students to continue his search. They combed old newspapers and other materials for clues. Gradually, a picture came into view.Captain Alfred Edwin McKay joined the British Royal Flying Corps in 1916. He downed ten enemy planes, outlived his entire squadron (中队) as a WWI flyer, spent some time as a flying instructor in England, then returned to the front, where he was eventually shot down over Belgium and killed in December 1917. But there’s more to his story. “For a brief time in 1916 he was probably the most famous pilot in the world,” says Broad. “He was credited with downing Oswald Boelcke, the most famous German pilot at the time.” Yet, in a letter home, McKay refused to take credit, saying that Boelcke had actually crashed into another German plane.McKay’s war records were destroyed during a World War II air bombing on London — an explanation for why he was all but forgotten.But now, thanks to the efforts of Broad and his students, a marker in McKay’s memory was placed on the university grounds in November 2007. “I found my eyes filling with tears as I read the word ‘deceased’ (阵亡) next to his name,” said Corey Everrett, a student who found a picture of Mckay in his uniform. “This was such a simple example of the fact that he had been a student just like us, but instead of finishing his time at Western, he chose to fight and die for his country.”56. What made Professor Broad continue his search for more information on McKay?A. A uniform. of McKay. B. A footnote about McKay.C. A book on McKay. D. A picture of McKay.

    The Theory of Everyone
      If Stephen Hawking lives until the year 2017, he will have lived more than 50 years longer than his doctors expected. When he was a college student, doctors discovered that he had a rare disease. This disease causes a gradual disintegration(分解)of the nerve cells in the brain cells that regulate voluntary muscle activity. Death almost always occurs within two or three years.
      Today Stephen Hawking cannot walk or speak. He cannot move his arms or his head. He cannot taste or smell anything. And yet this man is Professor of Mathematics at Cambridge University, a position held by the famous scientist Isaac Newton in 1669.
      Hawking is often described as the greatest scientist since Albert Einstein, but to the world outside science, he is also known as the man who made scientific theory understandable. His book, A Brief History of Time, has sold over eight million copies.
      He says that since he does not have to think about his body or do any of the things other men have to worry about, such as washing the car or working in the yard, he can dedicate all of his time to thinking. This puts him in the perfect position to find the answer to the question that he has dedicated his life to. His question is: Is there a complete theory of the universe and everything in it?
      Despite his tremendous physical disabilities, he has already made some very important discoveries about the origin of the universe, how the universe holds together, and how it will probably end. He has also been able to explain the secrets of “black holes” in space. Now he is looking for a set of rules that everything in our universe must obey. He calls it the Theory of Everything. He thinks that someone will have found the answer within the next 20 years.
      If Stephen Hawking is able to find his Theory of Everything, he will have given the world the opportunity to understand things that will change the whole nature of science and probably also the way we live.

    Text 4 In 1784,five years before he became president of the United States,George Washington,52,was nearly toothless.So he hired a dentist to transplant nine teeth into his jaw–having extracted them from the mouths of his slaves.That’s a far different image from the cherry-tree-chopping George most people remember from their history books.But recently,many historians have begun to focus on the roles slavery played in the lives of the founding generation.They have been spurred in part by DNA evidence made available in 1998,which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings.And only over the past 30 years have scholars examined history from the bottom up.Works of several historians reveal the moral compromises made by the nation’s early leaders and the fragile nature of the country’s infancy.More significantly,they argue that many of the Founding Fathers knew slavery was wrong–and yet most did little to fight it.More than anything,the historians say,the founders were hampered by the culture of their time.While Washington and Jefferson privately expressed distaste for slavery,they also understood that it was part of the political and economic bedrock of the country they helped to create.For one thing,the South could not afford to part with its slaves.Owning slaves was“like having a large bank account,”says Wiencek,author of An Imperfect God:George Washington,His Slaves,and the Creation of America.The southern states would not have signed the Constitution without protections for the“peculiar institution,”including a clause that counted a slave as three fifths of a man for purposes of congressional representation.And the statesmen’s political lives depended on slavery.The three-fifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College.Once in office,Jefferson extended slavery with the Louisiana Purchase in 1803;the new land was carved into 13 states,including three slave states.Still,Jefferson freed Hemings’s children–though not Hemings herself or his approximately 150 other slaves.Washington,who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War,overcame the strong opposition of his relatives to grant his slaves their freedom in his will.Only a decade earlier,such an act would have required legislative approval in Virginia.38.What do we learn about Thomas Jefferson?

    Text 1 Of all the changes that have taken place in English-language newspapers during the past quarter-century,perhaps the most far-reaching has been the inexorable decline in the scope and seriousness of their arts coverage.It is difficult to the point of impossibility for the average reader under the age of forty to imagine a time when high-quality arts criticism could be found in most big-city newspapers.Yet a considerable number of the most significant collections of criticism published in the 20th century consisted in large part of newspaper reviews.To read such books today is to marvel at the fact that their learned contents were once deemed suitable for publication in general-circulation dailies.We are even farther removed from the unfocused newspaper reviews published in England between the turn of the 20th century and the eve of World War II,at a time when newsprint was dirt-cheap and stylish arts criticism was considered an ornament to the publications in which it appeared.In those far-off days,it was taken for granted that the critics of major papers would write in detail and at length about the events they covered.Theirs was a serious business,and even those reviewers who wore their learning lightly,like George Bernard Shaw and Ernest Newman,could be trusted to know what they were about.These men believed in journalism as a calling,and were proud to be published in the daily press.“So few authors have brains enough or literary gift enough to keep their own end up in journalism,”Newman wrote,“that I am tempted to define‘journalism’as‘a term of contempt applied by writers who are not read to writers who are.’”Unfortunately,these critics are virtually forgotten.Neville Cardus,who wrote for the Manchester Guardian from 1917 until shortly before his death in 1975,is now known solely as a writer of essays on the game of cricket.During his lifetime,though,he was also one of England’s foremost classical-music critics,a stylist so widely admired that his Autobiography(1947)became a best-seller.He was knighted in 1967,the first music critic to be so honored.Yet only one of his books is now in print,and his vast body of writings on music is unknown save to specialists.Is there any chance that Cardus’s criticism will enjoy a revival?The prospect seems remote.Journalistic tastes had changed long before his death,and postmodern readers have little use for the richly upholstered Vicwardian prose in which he specialized.Moreover,the amateur tradition in music criticism has been in headlong retreat.24.What can be learned about Cardus according to the last two paragraphs?

    A.His music criticism may not appeal to readers today.
    B.His reputation as a music critic has long been in dispute.
    C.His style caters largely to modern specialists.
    D.His writings fail to follow the amateur tradition.

    答案:A
    解析:
    根据题干定位到文章最后两段。文章第四段提到“他写的书只有一本还在版,大部分作品都不为人所知”;第五段又提到“在他去世之前,新闻业的口味就变了,后现代的读者对他的作品没有兴趣”。所以A选项“他的音乐评论可能对现在的读者并没有吸引力”为正确答案。注意have little use for相当于not appeal to,同时本选项还有may,这个语气委婉的词,因为正确答案语气委婉。干扰选项B,原文没有提到他的名声有争议,所以无中生有。C项,“他的风格符合现在的专家”与本段最后一句相矛盾。D项移花接木,是利用最后一句话编造的选项。

    文章第一段介绍了华盛顿这样一段鲜为人知的故事,第二段则说拔牙的故事和华盛顿砍樱桃树的形象相差甚远,接着说,“许多历史学家开始关注奴隶制对开国元老那一代生活的影响”。从该句所在的结构可以明显判断出该句应该是对上文内容的一个总结,那么拔牙则正是反映华盛顿生活当中一个不为人知的方面,由此正确答案为D。C选项虽然与主题有些联系,但首段只谈到奴隶对华盛顿个人的作用,C项上升到整个美国历史,含义过于夸大;干扰项A和B都是就事论事,文章并未围绕医疗手段原始或奴隶制残忍性展开的。

    That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings.

    B.in its early days the U.S.was confronted with delicate situations.
    C.historians deliberately made up some stories of Jefferson’s life.
    D.political compromises are easily found throughout the

    答案:B
    解析:
    第二段内容开始部分提出文章的主题,即奴隶制在这些领导人的生活中扮演的角色,下文则围绕这一新的历史研究展开论述,最后两句总结研究发现,即早期领导人的道德妥协以及新生国家的脆弱性,开国元勋们明知奴隶制错误,却不尽力去推翻。B项中的in its early days和delicate与文中的the country’s infancy和fragile nature对应,故为正确选项。A项题意过宽,我们很难判断是否“widely applied”,在文中找不到信息支持,与文章主题无关;C项明显错误,历史学家的历史

His urge to go is held in check by his desire not be rude        (2)_____to his guest. If he did not care of his guest’s feelings he would      (3)_____simply get up out of his chair and to announce his departure.         (4)_____This is what his body wants to do, therefore his politeness          (5)_____glues his body to the chair and refuses to let him raise. It is at      (6)_____this point that he performs the chair-grasp IntentionMovement. He continues to talk to the guest and listen tohim, but leans forward and grasps the arms of the chair as          (7)_____about to push himself upwards. This is the first act he wouldmake if he were rising. If he were not hesitating, it would          (8)_____only last a fraction of a second. He would lean, push, rise,         (9)_____and be up. But now, instead, it lasts much longer. He holdshis“readiness-to-rise”post and keeps on holding it. It is as if       (10)_____his body had frozen at the get-ready moment.

    正确答案: 1.can→must 根据上文,可知主人是“必须(must)”而不是“可能(can)”离开。
    2.在 not 后加to
    not to be rude to his guest作定语修饰his desire。
    3.将of→for或about
    care for/about在意,在乎
    4.删除and或to 如果删除to,那么在这里连词and连接两个并列的谓语动词get up out of his chair和announce his departure。如果删除连词and。不定式to announce his departure则作目的状语。
    5.therefore→but 这里两个分句是转折关系,而不是原因与结果的关系。
    6.raise→rise
    raise是及物动词后必须跟宾语,而rise则是不及物动词,作“起立,起身”讲。
    7.在 as about 中间加入if或though
    as if/though后跟不定式,可表示“似乎要做……”之意。
    8.make → do 或 perform
    do/perform an act表示“采取行动”
    9.

    10.post→ posture post作“标志,位置,职位”,而posture作“姿势”讲。

  • 第23题:

    问答题
    When David is twice as old as he is now he will be four times as old as his daughter Jane will be in five years time. If in 1990, four years ago, he was four times as old as his daughter, in what year was she born?

    正确答案: In 1983
    解析:
    (由题目可知,四年前为1990年,则今年为1994年。可以设David的女儿今年为X岁,David为Y岁,根据题目条件可以列出一个两元一次方程组:4(X+5)=2Y; 4(X-4)=Y-4。解方程组可得:X=11,Y=32,即Jane今年11岁,又知今年为1994年,则1994-11=1983,即她出生于1983年。)
