根据以下材料，回答 40～43 问题。During a television play the sound man must be ready to make every sound as it is needed．Sound effects are of three kinds：real，imitated and recorded．Real sounds are those of doorbells，telephone bells，and other small objects easy to keep in a studio． But the sound man must imitate many sounds． For bacon fryin9，he crumples cellophane paper．A long sheet of metal hanging in a doorway makes thunder·He taps one rubber sink plunger and then another on a table to imitate a horse walking on pavement． For a horse galloping along a gravel road，the sound man can use the two halves of a coconut，pounding each in turn very fast on the table．Recorded sound effects are used for noises he cannot himself produce offstage．He pays records for such sounds as a rooster crowing， a train leaving a station， and a baby crying．The sound man is an important part of any television production．第 40 题 The sound man is important because he________A．is kept busyB．makes fl TV play more lifelikeC．1ets an actor know when to life a telephone receiverD．is always learning new methods
Can you hear This? When something creates a sound wave in a room or an auditorium, 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. Because each use of an auditorium calls for different reverberation. Speech needs to be understood clearly: therefore rooms used for talking must have a short 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 reflecting surfaces create large reflections. Parallel(平行的)walls reflect sound back and forth, creating a rapid, repetitive pulsing 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.文章(41~45)This passage is mainly about_____A.sound waves and their effects.B.the types of music orchestras play.C.walls of an auditorium.D.the design of an auditorium.
