1、2023年职称英语理工B阅读理解真题详解这篇2023年理工类B级考试的阅读理解的文章，这一篇文章是选择教材以外的。下面 就给同学们具体的来解析一下这篇文章。Can You Hear This?When something creates a sound wave in a room or an auditorium （礼堂），listeners hear the sound wave directly from the source. They also hear the reflections as the sound bounces off the walls, floor, and ce

2、iling. These are called the reflected wave or reverberant （反射的）sound , which can be heard even after the sound is no longer coming from the source .The reverberation time of an auditorium is determined by the volume or interior size of the auditorium. It is also determined by how well or how poorly

3、the walls, ceiling, floor, and contents of the room （including the people） absorb sound. There is no ideal reverberation time. The full-sound performance of music such as Wagner operas or Mahler symphonies should have a long reverberation time. The light, rapid musical passages of Bach or Mozart nee

4、d a reverberation time somewhere between.Acoustic problems often are caused by poor auditorium design. Smooth, curved （弯曲 的）reflecting surfaces create large reflections. Parallel（平彳j：的）walls reflect sound back and forth, creating a rapid, repetitive pulsing侑节奏的跳动）effect. Large pillars （柱）and corners

5、 can cause acoustic shadows as the sound waves try to pass around the object. Some of these problems can be solved by using absorbers and reflectors to change the reverberation time of a room. For example, hanging large reflectors, called clouds, over the performers will allow some sound frequencies

6、 to reflect and others to pass to achieve a pleasing mixture of sound.31. This Passage is mainly about. A. sound waves and their acoustic effect B. the types of music orchestras play C. walls of an auditoriumD. the design of an auditorium【正确答案】D【答案解析】第一步：本题是一个问文章的主旨大意的题目。其次步：依据技巧，先看文章的标题，是：Can You H

7、ear This?（你能听到这个吗？）依据 标题中的信息词，无法解除任何一个选项，因此须要接着看每个段落的内容。各个段落没有 明显的段落中心句，但是依据全文来看，文章都是在讲auditorium （礼堂）的设计对于声音的 反射所造成的影响。第一段是提出了 the reflected wave （反射波），其次段是说到了 auditorium （礼堂）的内部设计对于反射波持续的时间的影响，第三段就讲到了 auditorium （礼 堂）中的物体对于反射的影响。由此都可以看出是在讲auditorium （礼堂）的设计的相关内容。 对比四个选项，D选项符合原文的内容，因此为本题的正确答案。32. W

8、agner operas and Mahler symphonies sound fuller in an auditorium with. A. a short reverberation timeB. a long reverberation timeC. an intermediate reverberation timeD. no reverberation time【正确答案】B【答案解析】第一步：划出题干的信息词，有:Wagner operas, Mahler symphonies, auditoriumo 其次步：依据信息词回来到原文其次段第三句：The full-sound p

9、erformance of music such as Wagner operas or Mahler symphonies should have a long reverberation time.第三步：对比分析，得出答案。原文是说Wagner operas or Mahler symphonies有一个a long reverberation time （长的反射时间）。对比四个选项，B选项的a long reverberation time 与原文样，因此B选项为本题的正确答案。33. This passage suggests that a good auditorium shou

10、ld.A. achieve a pleasing mixture of soundB. get rid of all reflectionsC. not have absorbersD. have smooth surfaces【正确答案】A【答案解析】第一步：本题没有明显的信息词，但是可以依据选项的信息词回来到最终一段。题干是问一 个好的礼堂应当怎么样。其次步：依据信息词回来到原文最终段。从最终段第五句：Some of these problems can be solved by using absorbers and reflectors to change the reverberat

11、ion time of a room. 可以看出，前面提到的都是一些问题（problem）,因此都是好的礼堂不应当有的，即：Smooth, curved （弯曲的）reflecting surfaces, Parallel（平行的）walls, Large pillars （柱）and corners 对比之后就可以解除C和D两个选。再看A和B, B是说礼堂应当避开全部的同声，这个 说法明显太肯定，是错误的。因此只能选择A选项。A选项可以回来到最终一段的最终一 句：For example, hanging large reflectors, called clouds, over the pe

12、rformers w川 allow some sound frequencies to reflect and others to pass to achieve a pleasing mixture of sound.achieve a pleasing mixture of sound 与原文是一样的。34. Large pillars and corners may. A. make sound rich and fullB. be cures for sound problemsC. be sources of sound problems D. function as well as

13、 clouds【正确答案】C 【答案解析】第一步:划出题干的信息词，有:Large pillars, cornerso其次步：依据信息词回来到原文第三段第四句:Large pillars （tt） and corners can cause acoustic shadows as the sound waves try to pass around the object.第三步：对比分析，得出答案。原文是说Large pillars （柱）and comers会导致acoustic shadows （声影），依据后面一句的 Some of these problems can be solve

14、d.也可以知道， 这应当是一个问题，而acoustic shadows就这导致这个问题的缘由。对比四个选项，C选 项的be sources of sound problems就是指是问题的来源，与原文一样，因此C选项为本 题的正确答案。35. The word ,acoustic in the last paragraph has something to do with.A. performanceB. soundC. audienceD. weather【正确答案】B【答案解析】第一步：本题是一个词义改写题，目标词是acoustic,是问这个词是与什么有关的。其次步：在词典中查找到acoustic,意思是“听觉的，声学的，音响的”，明显是与声音有 关的，而且整篇文章也是在讲声&的反射的。对比四个选项的意思，B选项的sound表示声 音，为本题的正确答案。
