53. C　文中提到78%of the freshmen were eighteen years old，and 14%were nineteen.故此题应选C 92%。

52. B　本题要求考生在理解语篇信息的基础上对作者对论题的基本态度做出正确判断。作者在短文最后一段叙述了Business decisions are often made with many unknown and unknowable factors which would even puzzle best poker players. 由此我们可以判断出，在作者看来，一个人对事情做出决定，应当承认未知因素的存在，故最佳答案为B。

D　 这是一份调查报告。记叙了一份对刚入学的大学生的调查报告的结果：80%的学生在18岁；一半大学生远离父母的家；大多数大学生在城里或城附近长大；只有少数大学生的父母离异。

51. D　本题要求考生依据语篇情景猜测词语意义。作者在第三段首先叙述了One mistaken idea about business is that it can be treated as a game which we must normally play with very imperfect information. 接着笔锋一转指出，Business，politics， life itself are games which we must normally play with very imperfect information. 由作者对错误与正确观念两种截然不同的态度就可以推断出，“Quite the reverse”的意思是“Just the opposite”，故最佳答案为D。

50. B　这是一道推理判断题。根据短文第二段中，伟大数学家John von Neumann把游戏分成两类的理论，其中另一类是Then there are games of “imperfect information”， like poker， in which it is impossible to know in advance that one course of action is better than another. 便清楚地说明了不完善信息的一个重要因素是运气，故最佳答案为B。

48. D　推断题。问作者对戏剧学校的感觉如何?根据文章中最后一句观点句。“While all the　 leading schools say they place great importance on children getting good study results， the facts seem to suggest this is not always the case.”表明作者对普通学校给学生教育所达到的程度表示怀疑，这正好与D吻合，所以答案为D。

C　 这是一篇说明文。主要叙述了在作决定的时候人们的思维过程。

47. C　词义理解题。问professional work意指什么?根据文章中最后一段句子The school　 themselves admit that not all children will be successful in the profession for which　 they are being trained.中定语从句的叙述可推知它应指的是学校的戏剧表演训练，绝不是赚钱的表演B，也不是学校日常学习A，至于表演、唱歌、跳舞，那不是发生在放学后，而是through the other half of the day，所以答案为C. stage training at school。

46. D　推断题。依作者来看，一所好的戏剧学校应该怎样?根据文章中第二段句子:More worthy of the name “stage school” are those few places where children attend full time，with a training for the theatre and a general education.可推断出既提供教育又提供戏剧表演训练机会的才是一所好的戏剧学校。D正有此意，所以D为正确答案。

45. A　辨认事实题。问当人们意识到正和他们谈话的孩子们干什么去时，他们才不再感到不自在。文章第一段有这么一句话:“…the idea of children working is just unthinkable…until you told that the ‘work' they go off to is to go on the stage in a　 theatre.”当然答案A.attend a stage school最合句意。B、C、D与原文不符。

44. D　逻辑判断及构词法考查题。此句问David开创Computertown UK的目的何在?文章第二段最后一句to bring computers to people and make them(computers)“people-literate”，显而易见A、B、C与此不符。因为文章并未涉及计算机销售C和程序设计B，况且文章清楚表明不是利用专家 A。所以答案为 D.popularising computer (普及记算机应用)。popularising由popular(adj).加后缀-ise动词化并加-ing变化而来。

B 这篇文章说的是小学生抽空学艺“半艺”“半读”的社会现象，同时更表露了作者对这种现象的看法。

43. B　代词指代理解题.此题问第2段中句子 Although many people see this as a　 successful attempt to bring people closer to the computer，David doesn't see it that way中”it”指代什么?根据文章大义，显然排除A、C、D，故答案为B(使人们学会使用计算机)。
