Part IV Reading (1%*15=15%) Passage 1 Questions 1 through 5 are based on the following passage. In the past several decades, a number of chimps(猩猩) have been taught the ……………………………………………………………装 订 线
gestures of the American Sign Language (Ameslan). The results of these studies are hotly debated. A recent survey asked scientists to name the most significant discovery in recent years. Many replied that it was the failure of chimps to acquire language. About an equal number, however, believed the most significant discovery was the success of chimps to learn and use language. These opinions arise from differing definitions of language use.
To use language, it is first necessary to understand that a word is a symbol. Humans know, for example, that the word c-u-p is a symbol for the thing we drink from. Time after time, chimps have shown their understanding of the symbolic nature of language. Chimps trained at research centers across the nation have learned between 100 and 200 words. They are also able to name things in pictures, showing another level of understanding. In addition to learning the names of things (nouns), they have also learned the names of actions (verbs).
Critics of the early experiments argued that since chimps did not understand the concept of negating, they were not really using language. Sarah, a chimp trained at the University of California at Santa Barbara, showed an understanding not only of negating. She also showed an understanding of compound and complex sentences. Sarah learned to compose and read sentences by placing metal symbols on a metallic board. She once asked herself, “What is an apple not?” and correctly, and creatively, replied, “bread.”
Those who doubt that chimps have successfully learned a simple language place too much emphasis on comparing chimps to humans. Our language has developed over a long period of time, while chimps have only recently been exposed to language learning. Given their short exposure to language, chimps have demonstrated remarkable mastery.
56. The results of the experiment s on the chimp’s language acquisition
_____________.
A) were disclosed in a recent survey
B) were considered inaccurate by most of the scientists
C) were obtained from an equal number of chimps
D) were interpreted by the scientists in different ways
57. According to the passage, chimps have the ability to ___________.
A)understand language at more than one level
B)draw a simple picture of something such as a cup
C)make a distinction between some nouns and verbs
D)recognize the numbers from one to two hundred
58. The word “cup” is given as an example to illustrate ____________.
A)the language training of chimps
B)the process of language acquisition
C)the symbolic nature of language
D)the formation of an English word
59. It can be inferred from the passage that a chimp named Sarah ________.
A) understood simple sentences only
B) had no sense of negation at all
C) couldn’t understand complex sentences
D) could add “no” or “not” to a thought
60. In assessing the chimp’s language acquisition the author
emphasizes
___________.
A) the structure of sentences
B) the length of exposure to language
C) the approaches to language learning
D) the use of gestures
Passage 2
Questions 6 through 10 are based on the following passage. We hear a great deal about the literacy crisis, and a great deal of criticism has been directed at the educational system for causing it. Some 23 million adult Americans are “functionally illiterate,” unable to read newspapers or fill out job application forms, and the schools regularly produce large numbers of students who cannot pass easy minimum-competency tests. Critics lay the blame variously upon poor teaching, on ill-advised teaching methods and on the long trend in education away from the basics, a trend that reached its peak in the 1960’s and early 1970’s.
The problem, however, may have less to do with the educational system
than with the changes in public values. In 1765, John Adams claimed that “A native of America who cannot read or write is as rare an appearance as a comet or an earthquake.” The educational system of the late 18th and 19th centuries was much poorer than what we have today: the quality of teaching was low, facilities were grossly inadequate, and many children did not attend school at all. Yet by 1850 the adult literacy rate had reached 90 percent. It was considerably higher than the percentage of children attending school. The country was full of self-made readers and writers, people who had struggled to become literate but for whom the struggle had real meaning and definite rewards.
The meani ng is still there, and rewards are still available, but we don’t value ……………………………………………………………

literacy as we once did. The public worries about the high rates of functional illiteracy, but that same public spends an average of nearly 30 hours a week per person watching television. Half of that public never reads any kind of book; and it writes prose, when it writes at all, that has led to talk of a “writing crisis” on top of the literacy crisis.
What the history of literacy demonstrates is that preserving literacy is not and never has been a function that belongs solely to the schools. A highly literate society evolves out of deeply held values, values that cannot be isolated in a school system but must permeate the whole society.
61. By saying “A native of America … or an earthquake.” in 1765, John Adams meant that
________________.
A)nearly all the native Americans were literate
B)most Americans could neither read nor write
C)astronomy and geology were new to most Americans
D)comets were as rare as earthquakes in America
62. According to the passage, the high adult literacy rate in America in 1850 was due to
_____________.
A)its high quality of teaching
B)its good education system
C)the Americans’ strong desire for learning
D)the large percentage of children attending school
63. According to the author, the chief cause of the literacy crisis in present America is that
___________.
A)education is away from the basics
B)the educational system pays less attention to literacy
C)people no longer value literacy as they used to
D)people are no longer rewarded for their literacy
64. If the American public writes anything, it writes prose, which is a kind of __________.
A)poetic writing
B)highly literary writing
C)delicate descriptive writing
D)straightforward writing in a loose style
65. It can be concluded from the passage that ______________.
A)society plays an important role in preserving literacy
B)literacy should be more highly valued than sciences
C)the school system has nothing to do with literacy crisis
D) schools should provide students with more functional courses
Passage 3
Questions 11 through 15 are based on the following passage.
Much of the language used to describe monetary policy, such as “steering the economy to a soft landing” or “a touch of the brakes”, makes it sound like a precise science. No thing could be further from the truth. The link between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likens the conduct of monetary policy to driving a car with blackened windscreen, a cracked rearview mirror and a faulty steering wheel.
Given all these disadvantages, central bankers seem to have had much to boast about. Average inflation in the big seven industrial economies fell to a mere 2.3% last year, close to its lowest level in 30 years, before rising slightly to 2.5% this July. This is a long way below the double-digit rates which many countries experienced in the 1970s and early 1980s.
It is also less than most forecasters had predicted. In late 1994 the panel of economists which The Economist polls each month said that America’s inflation rate would average
3.5% in 1995. In fact, it fell to 2.6% in August, and is expected to average only about 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point below the rate predicted at the end of last year. This is no flash in the pan; over the past couple of years, inflation has been consistently lower than expected in Britain and America.
Economists have been particularly surprised by favorable inflation figures in Britain and the United States, since conventional measures suggest that both economies, and especially America’s, have little productive slack. American’s capacity utilization, for example, hit historically high levels earlier this year, and its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemployment ---- the rates below which inflation has taken off in the past.
Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful structural changes in the world have up-ended the old economic models that were based upon the historical link between growth and inflation.
66. According to the text, making monetary policy changes _________.
A. is comparable to driving a car with blackened windscreen
B. is similar to carrying out scientific work
C. will not influence the economy immediately
D. will have an immediate impact on the inflation rate ……………………………………………………………装 订 线…………………………………………………
67. According to the text, the inflation rate of many countries in early 1980s was once probably as high as __.
A. 30
B.2.3
C.3.5
D.2.6
68. According to the text we can learn that ______.
A. there is a clear relationship between inflation and interest rate
B. the economy always follows particular trends
C. the current economic problems are entirely predictable
D. the present economic situation is better than expected
69. By saying “This is no flash in the pan” (line 5, paragraph 3), the author means that _________.
A. inflation will disappear entirely
B. the inflation rate will rise again
C. the low inflation rate will continue
D. there is no inflation at present
70. How does the author feel about the present situation?

四川省大学英语二级阅读题
Passage 1 The origins of April Fools’ Day, sometimes called All Fools’ Day, are uncertain. Some see it as a celebration related to the turn of the seasons, while others believe it stems from the application of a new calendar. Ancient cultures celebrated New Year’s Day on or around April 1. In medieval times (中世纪) much of Europe celebrated March 25ch 25 as the beginning of the new year. In 1582, Pope (罗马教皇) Gregory XIII ordered a new calendar to replace the old Julian Calendar. The new calendar called for New Year’s Day to be celebrated on January 1. That year, France accepted the reformed calendar and shifted New Year’s day to Jan. 1. According to a popular explanation, many people either refused to accept the new date, o r did not learn about it, and continued to celebrate New Year’s Day on April 1. Other people began to make fun of these traditionalists, sending them on “fool’s errands” or trying to trick them into believing something false. Eventually, the practice spread throughout Europe. There are at least two difficulties with this explanation. The first is that it doesn’t fully explain why other European countries also observe April Fools’ Day. The Gregorian calendar was not applied by England until 1752, for example, but April Fools’ Day was already well established there by that point. The second is that we have no direct historical evidence for this explanation, only conjecture (猜测) which appears to have been made more recently. 1.Which of the following statem ents about April Fools’ Day is TRUE? A)It was observed by all the fools. B)It is observed in many countries. C)People have been sure about its origin. D)It is a legal holiday throughout the world. 2.According to the passage, New Year’s Day was celebra ted______. A)on or around April 1 in ancient cultures before 1582 B)on March 25 in Rome and India in ancient times C)on January 1. by all the people in France in 1582 D)on January 1. by people in England well after1752 3.In the fourth paragraph, the p hrase “fool’s errands” means ______ . A)fruitful tasks B)fruitless tasks C)simple tasks D)difficult tasks 4.Those who continued to celebrate New Year’s Day on April 1 in France after 1582 _____. A)were forced to accept the reformed calendar B)began to make fun of those traditionalists C)refused to be sent on “fool’s errands” that day D)were likely to be made fun of by others that day 5.Which of the following does not go against the belief that April Fools’ Day stems from the application of a new calendar? ______ A)Many people in France did not accept or learn about the change of New Year’s day then.
练习题2(答案)
1. 一种股票的市价为每股50美元，而以这种股票为基础资产的三个月期看涨期权的敲定价为每股45美元，如果这一看涨期权的交易单位为100股，那么，这一看涨期权的内在价值为（ 500美元 ），如果牌价表上的期权费为6美元，那么这一看涨期权的时间价值为（ 100美元 ）。 2.假设A 、B 公司都想借入1年期的100万美元借款，A 想借入与6个月期相关的浮动利率借款，B 想借入固定利率借款。两家公司信用等级不同，因此市场想它们提供的利率也不同（如下表所示），请简要说明两公司应如何运用利率互换 答：从表中可以看出，A 公司的借款利率均比B 公司低；但是在固定利率市场上A 比B 低1.2%，在浮动利率市场上A 仅比B 低0.5%。因此A 公司在两个市场上均具有绝对优势，但A 在固定利率市场上具有比较优势，B 在浮动利率市场上具有比较优势。所以，A 可以在其具有比较优势的固定利率市场上以10.8%的固定利率借入100万美元，B 在其具有比较优势的浮动利率市场上以LIBOR+0.75%的浮动利率借入100万美元，然后运用利率互换进行信用套利以达到降低筹资成本的目的。由于本金相同，双方不必交换本金，只交换利息现金流，即A 向B 支付浮动利息、收到固定利息（LIBOR+0.25%，11.15%，成本为LIBOR+0.25%-0.35%，节约0.35%），B 向A 支付固定利息、收到浮动利息（11.25%，LIBOR+0.25%， 成本为11.25%+0.5%，节约0.25%）。 3.假设某银行贷款期限为5年，每年的利率为10%,贷款票面价值（平价）是10000元，它同样也是该笔贷款目前的市场价值（价格），即该贷款的到期收益率为10%，请计算该贷款的久期。 答：年久期17.4100007.41698%)101(10000%)101(10005%)101(10000%)101(1000)1()1(5155 151==+++?++?+=+++=∑∑∑===t t t t n t n t t P y nF y tC 4.何为欧式期权的看涨看跌平价关系？ 答：（1）通过看涨看跌评价关系可以根据欧式看涨期权的价格算出看跌期权的价格。 5.在什么情况下进行多头套期保值或空头套期保值是合适的？ 答：在以下两种情况下可运用空头套期保值： ① 公司拥有一项资产并计划在未来售出这项资产；②公司目前并不拥有这项资跌期权的价格看涨期权的价格小于看权执行价格的现值，则）如果股票价格小于期跌期权的价格看涨期权的价格大于看权执行价格的现值，则）如果股票价格大于期跌期权的价格看涨期权的价格等于看权执行价格的现值，则）如果股票价格等于期调整方程得到：期权的大小。来推导看涨期权与看跌）还可以根据平价关系（） （3212t T r Ke S P C ---=-

气息训练课程
第一部分：气息训练资料 呼吸控制四字诀 1、深：指气息下沉，不提、不浅。 气息深可以防止说话声音发飘、发虚 练习方法： 1）用胸腹联合呼吸法发单元音a、o、e、i、u、ü，吸气七八成，控制着两肋与小腹形成的拮抗力拉住横隔，获得均匀而持久的气息，缓缓地发出单元音的延长音。 2）叹气练习：像平时叹一大口气那样，但要带着声音叹息，在声音落到底部，即提起的那口气叹下去时，就在这个位置和音高位置发延长音a。 注意：不要压喉；中途不要卡音；气不要上提，音高不提高。 2、通：指气息在胸腔里运动没有任何障碍，喉不紧，胸不紧，声音不在喉部卡 住，也不在胸部憋住。 检验方法：可用夸张四声来检验，用胸腹联合呼吸发发音，依次发bā……bá……bǎ……bà……的延长音，每个音程尽可能加大。四声不同的音高主要靠气息的运动来调节，一个是小腹的松紧变化，另一个是胸部支点的变化。 胸部支点： 声音的高低起伏反映在气息上会在前胸有不同的着力点、紧张点，这时由于音高不同所需要的气息压力不同的表现。 做夸张四声的练习，目的是用声调的高低升降变化，体会气息上下走通的感觉。一方面，从胸部支点的上下移动体会气息的运动；另一方面，从声音来检验气息是通的，还是憋在胸部，僵持在某一点上？或是卡在了喉部？必须防止又喉部肌肉的卡和松控制气息发出卡紧、发扁的所谓四声。 3、匀：指发声时气息的均匀和持久。 气息匀强调的是控制呼气的力量，而非前强后弱，或忽大忽小，或虽然气足但气短。 练习： a、数数； b、单元音的延长音；

No one has so set a whole world laughing as the little man with the walking stick and the oversized shoes. Much has been written about Chaplin's art and his career, and opinions have ranged widely. But perhaps those who called him "the truest human being of our time" came closest to the truth. Those who have called him a genius stress the timeless and common qualities in his work. It is an art filled with sad elements and deep human feeling, with which an audience cannot help but become involved. It is for these reasons, I believe, that the figure of Charlie has attracted generation after generation. All the writers who give accounts of Chaplin's life agree that Charlie's unhappy early years in the area in London where houses were dirty and worn had a great influence on his development and on the type of films he made. Chaplin himself emphasizes it in his memoirs (回忆录). The more one reads about his earliest period, the more one tends to agree. Indeed, his suffering youth had a lasting influence on him. Chaplin was never afraid to deal with subjects causing much disagreement in his films. He gave a humorous performance on war only a few weeks before the American soldiers came home from World War I in 1918. This was regarded as madness, but the performance was well received. So perfectly did it hit the nail on the head that even the returning soldiers found it impossible to hate it and deeply appreciated this short and humorous performance on what for them had been an unpleasant reality. Chaplin gave numerous performances attacking capital governments, satirizing (讽刺) the cruelty of the machine age, and even making fun of Hitler. Years after his death, the funny films of motion picture actor and director Charlie Chaplin continue to be well loved. He is particularly well known for his success as a creator of humorous presentations that make fun of people, the establishment, or networks. 1. All of the following about Charlie Chaplin are true except _______________. A. he was born in the USA B. he was a great film actor C. he had an unhappy early life D. he made fun of Hitler in one of his films 2.
