21、大学体系中，这种体系与其国家的体系截然不同。在日常工作中，他要面对哲学、课程安排和教学方法上的差异。访问教授和他的学生在各自的文化方面都缺乏一种共同点，所以外国教授需要明白美国学生已经了解了那些概念。在帮助外国教授使其适应新环境的同时，学校也必须作出某些调整，以充分发挥新人的优势。如何创造性地利用外国教职教员并不总为人所知，特别是在一些较小的学校中。这被认为是需要进一步研究的领域，其研究成果将对拥有外国教职员工的学院和大学产生重大的价值。47. 【答案】H)【解析】选of 。使用外国教师的优点和缺点必须仔细权衡，此处空格填介词of。48. 【答案】C)【解析】选considered。consi

23、存在的那些概念。54. 【答案】J)【解析】选make。“做些调整”用动词make。大学必须做出适当的调整。55. 【答案】E)【解析】选offer。offer意思是“提供，供应”。56. 【答案】A)【解析】选field。field意思是“领域”。这是一个有待进一步研究的领域。第四篇 关于摇滚Questions 47 to 56 are based on the following passage.Rock and roll is a genre of popular music that evolved in the United States in the late 1940s and

24、early 1950s. Its 47 lie mainly in blues, rhythm and blues, country, folk, gospel, and jazz. The style subsequently spread to the rest of the world and developed further, leading ultimately to 48 rock music.The term “rock and roll” now covers at least two different meanings, both in common usage. The

25、 American Heritage Dictionary and the Merriam-Webster Dictionary both 49 rock and roll as synonymous with rock music.50 , A defines the term as referring specifically to the music of the 1950s.Classic rock and roll is 51 played with one or two electric guitars, a string bass or an electric bass guit

26、ar, and a drum kit. In the 52 rock and roll styles of the late 1940s, either the piano or saxophone was often the lead instrument, but these were generally 53 or supplemented by the guitar in the middle to late 1950s.The massive popularity and eventual worldwide view of rock and roll gave it a 54 so

27、cial impact. Far beyond simply a musical style, rock and roll, as seen in movies and in the new medium of television, 55 lifestyles, fashion, attitudes, and language. It went on to spawn various sub-genres, often without the initially 56 backbeat, that are now more commonly called simply “rock music

28、” or “rock”.A) define I) followed B) characteristic J) modernC) unique K) explanation D) roots L) ConverselyE) usually M) replaced F) Basically N) prepareG) earliest O) seldoH) influencedSection A47. D)。此处需要一个名词。此处讲的是摇滚主要植根于布鲁斯、节奏布鲁斯、乡村音乐、民歌、福音歌以及爵士乐。48. J)。此处需要一个形容词。参见上题解析可知，摇滚最终发展为现代的摇滚音乐。49. A)。此

29、处需要一个动词。根据前面出现的两个词典给出的解释及后面的内容可以推断，这里是对摇滚进行定义。50. L)。此处需要一个副词。根据上下文可知，ALL与前两个词典的定义不同，它将摇滚定义为20世纪50年代的音乐而不是现代音乐。51. E)。此处需要一个副词。根据上下文可知，古典摇滚乐通常由如下乐器合奏：一两把电吉他;一个弦贝司或电贝司;一组架子鼓。52. G)。此处需要一个形容词。根据下文出现的1940s这个时间可知，这里讲的是20世纪40年代末期出现的最早的摇滚风格。53. M)。此处需要一个动词。根据下文“or supplemented by the guitar”可知，钢琴与萨克斯风这些早期

30、主打乐器被20世纪50年代中后期的吉他所取代或补充。54. C)。此处需要一个形容词。根据上下文可知，摇滚对社会产生的影响是独特的。55. H)。此处需要一个动词。此处讲的是，除了音乐风格，在电影及电视媒体里均可见摇滚对生活风格、流行、态度及语言的影响。56. B)。此处需要一个形容词。此处讲摇滚继续发展成各种不同的类型，一般都没有摇滚乐初期特有的强节奏基调。第五篇 关于美国的专利体系Questions 47 to 56 are based on the following passage.The American patent system, provided for in the Cons

31、titution, was designed to encourage the creation and use of new technology. An inventor would describe the invention, both in writing and with drawings, and _47_ the description with a model to a government official. If the invention was judged to be _48_ and beneficial, the official would give the

32、inventor a patent. The patent meant that for 14 years the inventor owned the new invention. Inventors could _49_ their ideas to manufacturers or just use them themselves. The government would not _50_ any other patent for the same idea, and the inventor could _51_ anyone of using the patented idea w

33、ith- out paying the owner of the patent for _52_ to use it.A useful patent meant that the inventor could make a lot of money. In exchange for this gover- nmental protection, the government published the patent _53_ , which had to provide enough information so that other people could understand the i

34、nventionthus adding to the general_54_technological knowledge. And at the end of the 14 years, anyone could use the invention for_55_.The idea behind the patent system was twofold: it would increase the amount of technology, by providing a way for people to make money out of new ideas, and it would

35、make new technology widely available, by publicizing ideas that might _56_ be kept as trade secrets.A) license I ) specifications B) however J ) yield C) accuse K) issue D) submit L) chargeE) convenient M) available F) permission N) otherwise G) enable O) original H) free47.D 此处需要一个动词。本句叙述申请专利的程序：申请

36、人申请专利时需要对发明进行具体描述，然后将描述和样品一同提交政府官员，故填submit一词。48.O 此处需要填入一个形容词和beneficial并列作表语。此句介绍政府官员签发专利的条件是原创性和有用性，故填original。49.A 空格前为情态动词could，所以此处需要填入一个动词原形。此处和or后面的use them themselves意义上是对应的。根据常识，申请人获得专利后，专利当然可以自己使用，也可以转让给其他人，故填license“许可，特许”。50.K 此处需要填入一个动词原形。政府为一项发明签发专利后，当然不能再为同样的创意签发专利，故填issue“签发，发行”。51.

37、C 空格前为情态动词could，所以此处需要填入一个动词原形和后面的介词of 搭配使用。句子用without 引导条件如果没有支付费并获准使用就擅自使用该专利，因为专利受法律保护，发明人有权对其进行起诉。accuse和charge都有“控告，控诉”的意思，但是用法不同，分别为accuse sb. of sth.和charge sb. with sth. ,故排除charge。52.F 此处需要填入一个名词作介词for 的宾语。使用专利的人要向专利发明人支付费用， 获得使用权后才能取得专利的使用权。故填permission“许可”。53.I 此处需要一个名词。对于专利，政府一方面实施保护政策，另

38、一方面，为了让大众了解专利的相关知识，政府会出版专利的详细说明，所以填specifications“说明书”。54.M 此处需要一个形容词，修饰其后的名词knowledge。政府出版专利详细说明的目的是让大众能够了解发明，所以填available“可利用的” 。55.H 上一段中提到美国政府在专利申诉的14年内进行保护，在这14年申报人拥有专利的所有权，超过14年，任何人都可以免费使用该专利。此处考查固定短语 for fre“免费的”。 56.N 句子主谓结构完整，空格处可以填入一个副词。publicizing ideas和定语从句中的be kept as trade secrets 之间是对

39、比关系，因此需要填入一个表示转折意义的副词 otherwise。otherwise 和 however 都可以表示引导意义的转折，但however常用插入语，其前后需要加逗号，而otherwise 不需要。第六篇 关于孕妇饮食Questions 11 to 20 are based on the following passage.A pioneering study into the effects of a mothers fat intake during pregnancy on her childs health when he or she grows up is being la

40、unched at the University of Southampton.The research will investigate whether the type and amount of fat a mother eats during pregnancy 11 the risk of heart disease, 12 high blood pressure, in her child when he or she reaches adulthood.Although the link between high fat diets and high blood pressure

44、how much fat they should eat and what types of fat they should avoid.”A) funded I) consume B) diagnosis J) coveringC) including K) influences D) founded L) notoriousE) changed M) effects F) enough N) affectsG) findings O) prestigiousH) limitedSection A11. K)。此处讲孕妇摄入的脂肪量和种类是否对心脏病的患病率有影响。12. C)。此处讲研究还

45、包括孕妇摄入的脂肪量和种类同高血压患病率之间的关系。13. H)。此处讲尽管人们熟知高脂肪饮食与高血压之间有必然的联系，但是对于母亲饮食习惯与她的孩子患高血压的风险之间的相关研究却比较少。14. A)。此处讲该项研究是由英国心脏病基金会资助的。15. O)。prestigious的意思是“著名的，有声望的”。此处讲这项很有名的基金是英国心脏病基金会为加大对心脏病研究而投入的资金的一部分。16. B)。此处讲这部分慈善基金用于针对心脏病的起因、预防、诊断与治疗方面的研究工作。17. E)。此处需要动词的过去分词，A)和H)已经选过，只剩余D)和E)，而此处讲的是我们饮食中的脂肪的种类和数量在过去

46、的50年里已经发生变化。D)项的意思是“建立”，与句意不符。18. I)。此处讲孕妇和我们饮食相同，consume的意思是“消耗”，符合文意。19. M)。此处讲虽然孕妇和我们饮食相同，但是我们对孕妇饮食中脂肪的改变对其孩子未来健康和发育的影响知之甚少。此处是指饮食中脂肪改变所起的作用。要用名词形式effect;affect是动词。20. G)。此处是说研究结果可以帮助我们为孕妇提一些建议，该摄入多少脂肪以及什么样的脂肪应该避免摄入。第七篇 关于新型眼镜Questions 47 to 56 are based on the following passage.It seems you alwa
