【解析】
这是一篇说明文。文章主要介绍了一些声音技术领域的发明创造，包括声音可以用作武器的
远程声学设备、用来阻止有害声音影响你的静音机以及定向音响技术。
【46题详解】
推理判断题。根据第二段中的”It produces a deafening sound so painful that it temporarily
disables a person. The noise from the LRAD is directed like a ray of light and travels only into the
ears of that person, but it is not
deadly.”可知它发出震耳欲聋的声音，这种声音令人如此痛苦以至于它会使人暂时丧失能力。
LRAD发出的噪音像光线一样被引导，只进入那个人的耳朵，但不会致命。由此可推知，LR
AD会导致暂时性听力损失。故选A。
【47题详解】
细节理解题。根据第三段中的”Well, it functions by analyzing the waves of the incoming sound
and creating a second set of outgoing waves. The two sets of waves cancel each other out. Simply
turn the machine on point it at the target, and your peace and quiet comes
back.”可知，它的功能是通过分析传入声音的波，并产生第二组传出的波。这两组波会相互
抵消。只要打开机器对准目标，你的宁静就会回来。由此可知，静音机是一种专门设计用来
阻止有害声音影响你的设备。故选D。
【48题详解】
细节理解题。根据最后一段中的”A spotlight lights up only one section of a stage; similarly, a
“spotsound” creates a circle of sound in one targeted
area.”可知，聚光灯只能照亮舞台的一个部分；类似地，一个”spotsound”在一个目标区域创建
一个声音圈。由此可知，spotsounds和聚光灯的共同特性是它们可以被定向到一个特定的区域
，故选D。

细节理解题。根据最后一段中的”A spotlight lights up only one section of a stage;
similarly,”spotsound” creates a circle of sound in on targeted area. This can be useful for businesses
such as restaurants and stores because it offers a new way to attract customers. Restaurants can offer
a choice of music along with the various food choice on the menu, allowing customers more control
over the atmosphere in which they are
dining.”可知，聚光灯只能照亮舞台的一个部分；类似地，一个”spotsound”在一个目标区域创
建一个声音圈。这对餐馆和商店等企业很有用，因为它提供了一种吸引顾客的新方式。餐厅
可以提供音乐选择与菜单上的各种食物选择，让顾客更多地控制气氛，在他们用餐。由此可
知，定向音响可以用于不同的商业音乐选择。故选C。
【50题详解】
主旨大意题。根据第一段中的”In the past, sound engineers worked in the back rooms of recording
studios, but many of today's sound professionals are sharing their knowledge and experience with
professionals in other fields to create new products based on the phenomenon we call
sound.”可知，在过去，音响工程师在录音室的后室工作，但今天的许多音响专业人士正在与
其他领域的专业人士分享他们的知识和经验，以我们所谓的声音现象为基础创造新产品。结
合下文具体内容可知，本文着重论述了声音技术领域的发明创造。故选B。
D
After years of observing human nature, I have decided that two qualities make the difference
between men of great achievement and men of average performance curiosity and discontent. I have
never known an outstanding man who lacked either. And I have never known an average man who
had both. The two belong together.
Together, these deep human urges (驱策力) count for much more that ambition. Galileo was
not merely ambitious when he dropped objects of varying weights from the Leaning Tower at Pisa
and timed their fall to the ground. Like Galileo, all the great names in history were curious and asked
in discontent, “Why? Why? Why?”
Fortunately, curiosity and discontent don’t have to be learned. We are born with them and need
only recapture them.
“The great man,” said Mencius (孟子), “is he who does not lose his child’s heart.” Yet most of
us do lose it. We stop asking questions. We stop challenging custom. We just follow the crowd. And

the crowd desires restful average. It encourages us to occupy our own little corner, to avoid foolish
leaps into the dark, to be satisfied.
Most of us meet new people, and new ideas, with hesitation. But once having met and liked
them, we think how terrible it would have been, had we missed the chance. We will probably have to
force ourselves to waken our curiosity and discontent and keep them awake.
How should you start? Modestly, so as not to become discouraged. I think of one friend who
couldn’t arrange flowers to satisfy herself. She was curious about how the experts did it. How she is
one of the experts, writing books on flower arrangement.
One way to begin is to answer your own excuses. You haven’t any special ability? Most people
don’t; there are only a few geniuses. You haven’t any time? That’s good, because it’s always the
people with no time who get things done. Harriet Stowe, mother of six, wrote parts of Uncle Tom’s
Cabin while cooking. You’re too old? Remember that Thomas Costain was 57 when he published
his first novel, and that Grandma Moses showed her first pictures when she was 78.
However you start, remember there is no better time to start than right now, for you’ll never be
more alive than you are at this moment.
