2016年职称英语理工B阅读理解真题详解这篇2016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。下面就给同学们详细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 ceiling. 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 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 need 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(平行的) walls reflect sound back and forth, creating a rapid, repetitive pulsing(有节奏的跳动)effect. Large pillars (柱) and corners 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 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 effectB. the types of music orchestras playC. 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。第二步：根据技巧，先看文章的标题，是：Can You Hear This?（你能听到这个吗？）根据标题中的信息词，无法排除任何一个选项，因此需要继续看每个段落的内容。各个段落没有明显的段落中心句，但是根据全文来看，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），第二段是说到了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. Wagner 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，auditorium。第二步：根据信息词回归到原文第二段第三句：The full-sound performance 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与原文一致，因此B选项为本题的正确答案。33. This passage suggests that a good auditorium should_.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，但是可以根据选项的信息词回归到最后一段。题干是问一个好的礼堂应该怎么样。第二步：根据信息词回归到原文最后一段。从最后一段第五句：Some of these problems can be solved by using absorbers and reflectors to change the reverberation 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该有的，即：Smooth, curved (弯曲的)reflecting surfaces，Parallel(平行的) walls，Large pillars (柱) and corners。对比之后就可以排除C和D两个选。再看A和B，B是说礼堂应该避免所有的回声，这个说法显然太绝对，是错误的。因此只能选择A选项。A选项可以回归到最后一段的最后一句：For example, hanging large reflectors, called clouds, over the performers will allow some sound frequencies to reflect and others to pass to achieve a pleasing mixture of sound.achieve a pleasing mixture of sound与原文是一致的。34. Large pillars and corners may_.A. make sound rich and fullB. be cures for sound problemsC. be sources of sound problemsD. function as well as clouds【正确答案】C【答案解析】第一步：划出题干的信息词，有：Large pillars，corners。第二步：根据信息词回归到原文第三段第四句：Large pillars (柱) 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 corners会导致acoustic shadows（声影），根据后面一句的Some of these problems can be solved.也可以知道，这应该是一个问题，而acoustic shadows就这导致这个问题的原因。对比四个选项，C选项的be sources of sound problems就是指是问题的来源，与原文一致，因此C选项为本题的正确答案。35. The word “acoustic” in the last paragraph has som
