Section B Short Answer Questions (占总分的5%)
Directions: In this part there is a short passage with five questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words (not exceeding 10 words).
Our world is filled with sounds we never hear. The human auditory(听觉的) range is limited to begin with: if we could hear sounds lower than 20 vibrations per second, we would be driven mad by the rumblings and creakings of our muscles, intestines and heartbeats; every step we take would sound like an explosion. But even with our auditory range we select, focus, pay attention to a few sounds and blot out the rest. We are so assaulted(困扰) by sound that we continually “turn off”. But in the process we shut out the glorious symphony(交响乐) of sound in which the living world is bathed.
The sound tormented city dweller who habitually “turns off his audio” loses a dimension of social reality. Some people, for example, possess the ability to enter a crowded room and from the sounds encountered know immediately the mood, pace and direction of the group assembled. Everything becomes more real when heard as well as seen. It is, in fact, quite hard really to know a person by sight alone, without hearing his voice. And it is not just the sound of the voice that informs.
