2022年考博英语-宁波大学考前提分综合测验卷（附带答案及详解）1. 单选题Ragtime is a musical form that synthesizes folk melodies and musical techniques into a brief quadrille-like structure, designed to be played (exactly as written) on the piano. A strong analogy exists between European composers like Ralph Vaughan Williams, Edvard Grieg, and Anton Dvorak who combined folk tunes and their own original materials in larger compositions and the pioneer ragtime composers in the United States. Composers like Scott Joplin and James Scott were in a sense collectors or musicologists collecting dance and folk music in Black communities and consciously shaping it into brief suites or anthologies called piano rags.It has sometimes been charged that ragtime is mechanical. For instance, Wilfred Mellers comments “rags were transferred to the Pianola roll and even if not played by a machine, should be played like a machine, with meticulous precision.” However, there is no reason to assume that ragtime is inherently mechanical simply because commercial manufacturers applied a mechanical recording method to ragtime, the only way to record pianos at that date. Ragtimes is not a mechanical precision, and it is not precision limited to the style of performance, it arises from ragtimes following a well-defined form and obeying simple rules within that form.The classic formula for the piano rag disposes three to five themes in sixteen-bar strains, often organized with repeats. The rag opens with a bright memorable strain or theme, followed by a similar theme, leading to a trio of marked lyrical character, with the structure concluded by a lyrical strain that parallels the rhythmic developments of the earlier themes. The aim of the structure is to rise from one theme to another in a stair-step manner, ending on a note of triumph or exhilaration. Typically each strain is divided into two 8-bar segments that are essentially alike, so the rhythmic-melodic unit of ragtime is only eight bars of 2/4 measure. Therefore, themes must be brief with clear, sharp melodic figures. Not concerned with development of musical themes, the ragtime composer instead sets a theme down intact in finished form, and links it to various related themes. Tension in ragtime compositions arises from a polarity between two basic ingredients: a continuous bass called by jazz musicians a boomchick bassin the pianists left hand and its melodic syncopated counterpart in the right hand.Ragtime remains distinct from jazz both as an institutional style and as a genre. Ragtime style stresses a pattern of repeated rhythms, not the constant inventions and variations of Jazz. As a genre ragtime requires strict attention of structure, not inventiveness or virtuosity. It exists as a tradition, a set of conventions, a body of written scores, separate from the individual players associated with it. In this sense ragtime is more akin to folk music of the nineteenth century than to jazz.36. According to Paragraph 1, Ralph Vaughan Williams, Anton Dvorak, and Scott Joplin are similar in that they all _.37. The word “inherently” in Paragraph 2 can be best replaced by _.38. According to Paragraph 3, all the following are what the ragtime composer most concerned with EXCEPT _.39. According to Paragraph 4, what are the main differences between ragtime and jazz?40. It can inferred that the author of the passage believes that the most important feature of ragtime music is its _.问题1选项A.conducted research into musicological historyB.wrote original compositions based on folk tunesC.collected and recorded abbreviated piano suitesD.created intricate sonata-like musical structures问题2选项A.intrinsicallyB.artificiallyC.monotonouslyD.apparently问题3选项A.development of musical themesB.a subject down intact in finished formC.clear, sharp melodic figuresD.connecting it to various related subjects问题4选项A.An instrumental and musical techniques.B.An instrumental manner and a melody.C.A genre and musical techniques.D.An instrumental manner and a genre.问题5选项A.formal structureB.emotional rangeC.improvisational opportunitiesD.role as a forerunner of jazz【答案】第1题:B第2题:A第3题:A第4题:D第5题:A【解析】36.【选项释义】36. According to Paragraph 1, Ralph Vaughan Williams, Anton Dvorak, and Scott Joplin are similar in that they all _. 36. 根据第一段，拉尔夫沃恩威廉姆斯、安东德沃夏克和斯科特乔普林都_，这一点很相似。A. conducted research into musicological history A. 对音乐学历史进行了研究B. wrote original compositions based on folk tunes B. 是根据民间曲调创作的原创作品C. collected and recorded abbreviated piano suites C. 收集并录制了简短的钢琴组曲D. created intricate sonata-like musical structures D. 创造了复杂的奏鸣曲式的音乐结构【考查点】事实细节题。【解题思路】定位第一段“雷格泰姆是一种音乐形式，它将民间旋律（folk melodies）和音乐技巧综合成一种简短的类似方舞舞曲的形式，严格地按照创作一样在钢琴上演奏。拉尔夫沃恩威廉姆斯、爱德华格里格和安东德沃夏克等欧洲作曲家与美国的先驱拉雷格泰姆作曲家有着强烈的相似之处。像斯科特乔普林和詹姆斯斯科特这样的作曲家在某种意义上是收藏家或音乐学家，他们收集黑人社区的舞蹈和民间音乐（folk music），并有意识地把它们编成简短的组曲或选集（consciously shaping it into brief suites or anthologies），称为钢琴散拍乐曲。”，从中我们可知，雷格泰姆音乐是将民间旋律和音乐技巧结合，并在钢琴上演奏，拉尔夫沃恩威廉姆斯、安东德沃夏克和雷格泰姆风格类似，而斯科特乔普林也是收集民间音乐并编曲，其中的关键词是folk music，所以他们的相似之处就是，他们都是根据民间旋律创作作品，B项正确。【干扰项排除】A、D选项在该段没有提到，属于无中生有；C选项只是针对斯科特乔普林来说，并不全面，属于以偏概全。37.【选项释义】37. The word “inherently” in Paragraph 2 can be best replaced by _. 37. 第二段中的“inherently”一词最好用_代替。A. intrinsically A. 本质地，固有的B. artificially B. 人工地C. monotonously C. 无变化地，单调地D. apparently D. 显然地【考查点】词义推测题。【解题思路】定位第二段第三句“然而，没有理由仅因为商业制造商采用了一种机械的录音方法来录制散拍乐，而这是当时录制钢琴音乐的唯一方法，就认为散拍乐inherently就是呆板的”，在第一句也同样提到“有时人们认为散拍乐是呆板的”，从中我们可以推测，inherently表示“本来的”的意思，所以A项正确。【干扰项排除】B、C、D选项均不正确，属于曲解原文。38.【选项释义】38. According to Paragraph 3, all the following are what the ragtime composer most concerned with EXCEPT _. 38. 根据第三段，除了_，下面所有的都是散拍乐曲作曲家最关心的。A. development of musical themes A. 音乐主题发展B. a subject down intact in finished form B. 一个完整的主题C. clear, sharp melodic figures C. 清晰的、尖锐的旋律D. connecting it to various related subjects D. 将其与各种相关主题联系起来【考查点】事实细节题。【解题思路】定位第三段倒数第二句“散拍乐作曲家关心的不是音乐主题的发展（Not concerned with development of musical themes），而是把一个完整的主题（a theme）以完整的形式记录下来，并把它与各种相关的主题联系起来（links it to various related themes）”，以及倒数第三句“因此，主题必须是简短的，清晰的，尖锐的旋律（clear, sharp melodic figures）”，从中可知A项是散拍乐曲作曲家不关心的。因此，该题选择A项正确。【干扰项排除】B、C、D选项均是散拍乐曲作曲家关心的。39.【选项释义】39. According to Paragraph 4, what are the main differences between ragtime and jazz? 39. 根据第四段，散拍乐和爵士乐的主要区别是什么？A. An instrumental and musical techniques. A. 一种乐器技巧和音乐技巧。B. An instrumental manner and a melody. B. 一种乐器方法和旋律。C. A genre and musical techniques. C. 音乐流派和音乐技巧。D. An instrumental manner and a genre. D. 一种乐器方法和流派。【考查点】事实细节题。【解题思路】定位至第四段，文中提到“无论是作为一种器乐风格（institutional style）还是一种流派（genre），散拍乐都与爵士乐截然不同”，从中可知，散拍乐和爵士乐主要在于institutional style和genre上的区别，D选项表达最完整，因此正确。【干扰项排除】A、B、C选项表达不全面，属于以偏概全。40.【选项释义】40. It can inferred that the author of the passage believes that the most important feature of ragtime music is its _. 40. 可以推断出，文章的作者认为散拍乐最重要的特征是它的_。A. formal structure A. 形式结构B. emotional range B. 情绪广度C. improvisational opportunities C. 即兴机会D. role as a forerunner of jazz D. 爵士乐先驱的角色【考查点】推理判断题。【解题思路】根据第二段最后一句“散拍乐的精确性不是一种呆板的精确，这种精确也并不局限于表演风格，它来自于散拍乐遵循的一个明确定义的形式（a well-defined form），并在这个形式中遵守简单的规则”，第三段第一句“钢琴散拍乐的经典形式（classic formula）就是在16小节的旋律中安排3到5个主题，并且经常以重复的形式组织起来（organized with repeats）”，以及最后一段中的“散拍乐风格强调的是重复的音乐节奏（a pattern of repeated rhythms）散拍乐要求严格注意结构（requires strict attention of structure）”，从中我们可以看出，散拍乐的特点就是遵循明确的形式规则和编曲结构，所以A项正确。【干扰项排除】B选项属于编曲结构的特点之一，但并不全面，属于以偏概全；C选项没有提到，属于无中生有；D选项定位文章最后一句“散拍乐与其说是爵士乐，不如说是19世纪的民间音乐”可知，选项中的forerunner并不符合原文，属于反向干扰。2. 单选题The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise.

The situation for our citys children is terrible. Yet while I acknowledge the seriousness of the work we face, I want to be clear about something: I do not blame teachers for the low achievement levels.I have talked with too many teachers to believe this is their fault. I have watched them pour their energy into engaging every student. I know they are working furiously in a system that for many years has not appreciated themsometimes not even paying them on time or providing textbooks. Those who categorically blame teachers for the failures of our system are simply wrong.Rather, teachers are the solution to the vexing problems facing urban education.In the coming weeks, we will submit a final proposal for a new teacher contract. Through it and other reforms, we can create, together, the most effective educator force in the country. Our key goals:A growth model of achievement. Many teachers inherit classes of students who are far behind academically. Yet some teachers, even with minimal support, move their students two to three grade levels ahead in a year. Teachers will not be evaluated on an absolute measure but on how far they take their students.Protection from arbitrary firings. Some teachers are concerned a principal may want to fire them for reasons unrelated to performance. While principals who do this risk their own jobs (firing effective teachers is a sure way to lower school achievement), we will ensure protections for teachers. We need a fair and transparent process, free from bias and haste, designed with teachers input.Professional development and support. Teachers have told me that many of their hesitations about the contract center on the pressures that teachers face: “What if my school does not support me? What if I am working my tail off and I still have weeks when my patience is thin and things beyond my control are causing problems?”Our proposal will provide a framework to navigate these questions with strong programs to support and develop teachers as professionals. Neither will we forget the small things that can weigh down great teachers. For example, we want to reimburse those who buy supplies for their classrooms or use their cell phones to call students and families. We want to compensate teachers when they cover classes for others. I was a teacher. I know how these things add up.21. Which of the following statements is true according to the text?22.
