问题      The listener has a given amount of energy to expend in completing the communication process. Any distraction that demands part of that energy will diminish the probability that communication will take place. One of the easiest distractions to eliminate is the too soft voice. You Will find it necessary to adjust your voice level to accommodate the size of the room, the number of people in the audience, the furnishings, and the ambient noise level.
     The desired level is one that seems slightly greater than that normally heard in conversation. If the room is large and filled with people, you will have to put an appropriate amount of power in your voice to be easily heard. In some cases, you may require electronic amplification, which will usually enable you to speak in an ordinary conversational tone.
     Furnishings such as heavy carpets and drapes absorb a good deal of sound, thereby creating a deadening effect on the speaker’s voice. You should be able to judge the effects of the furnishings after speaking the first few sentences. You can then modify your voice level as necessary to account for any sound-absorbing material.
     The ambient noise in the room may be made up of motor sounds from and overhead projector, air-conditioning, outside traffic, etc. You may find it necessary to vary your voice level at times to adjust for changes in the ambient noise level.
    Finally, you should be aware of cues from members of the audience who may communicate by body language an inability to hear what you are saying.
The second sentence in the first paragraph intends to render the idea that______.
选项 A、distractions will render communication unlikely to happen
B、attention to the audience in public speech is most important
C、it takes great effort to overcome any distraction in public communication
D、it is impossible to communicate when the audience are distracted from the speech
答案A
解析 提问部分意为：“第一段第二句旨在说明……”。选择项A意为：“干扰会影响交流的进行(或：干扰会使交流难以进行)。”原文第一、二句指出：在完成交流的过程中，听众要消耗一定量的能量(指其注意力等)，如果有干扰因素占去这一能量的一部分(指使听众分b等)，达成交流的可能性就会降低。本文主要谈的是从演讲者的角度如何克服干扰、调整音量，以确保交流的顺利进行。
