警报器救盲人
如果看不见，那你可能会因找不到路而逃不出一幢失火楼房，那将是致命的。英国利兹市的一家公司发明的一种可指方向的警报器可能会把你引向出口。
声音警报是一家由利兹大学设立的公司。该公司现在正在为位于萨莫塞特的一家盲人收容所和位于卡姆布雷亚的一家盲人资源中心安装此种装置。这种警报器发出的频率范围广，使人脑可以判断出声音的来源。
该公司的戴博拉威星顿称此种警报器使用人类可以听到的大部分音频。她说：它们是一种突出的频谱连续而均匀的噪音。人们感觉它们听上去就像是收音机发出的静电噪声，其在救人方面潜力巨大。
她进行了一次试验。她让人们在一所充满浓烟的大屋子里设法找到出路，同时她用热效应成像摄像机进行拍摄。在没有警报器时，这些人用了近4分钟才找到门，而在警报器的指引下，只用了15秒。
她在大学里对人脑如何处理声音进行研究，并提出与波段窄的频率相比，人们更容易发现波段宽的音响源。基于此理论的警报器已被应用于急救车上。
这种警报器也容纳了音频的升降，以指示人们上、下楼。这种设备是得到英国核燃料组织的大笔资助才开发成功的。[

文章精读：
1. If you cannot see, you may not be able to find your way out of a burning building ---- and that could be fatal.
2. A company in Leeds could change all that ___1__ directional sound alarms capable of guiding you to the exit.
A. without B. with C. having D. selling
分析：通过阅读我们可以看出，空格后是一种装置，用它来改变当火灾发生时找不到出口的危险境况，所以要表达用。。。。装置意思的只能用介词with，带着、带有。本句的意思是：利兹市一家公司发明的一种可指方向的声音警报器能引导你到出口。
3. Sound Alert, a company ___2___ the University of Leeds, is installing the alarms in a residential home for ___3__ people in Sommerset and a resource centre for the blind in Cumbria.
A. run by B. changed by
C. decorated by D. criticized by
分析：我们知道Sound Alert是一家公司的名字，从语意上判断应该是由某人经营，因此选择答案A较为合适。
3. A. slow慢的 B. deaf聋的 C. blind瞎的 D. lame瘸的
分析：这篇文章的核心内容就是有关盲人警报器的，而且后半句也提到a resource centre for the blind ，所以顺理成章地得出结论应是C。
4. ___4___ produce a wide range of frequencies that enable the brain to determine where the ___5__ is coming from.
4. A. Alarms B. Alarm C. The alarm D. The alarms
分析：我们知道该空的名词应出现在前文，上一句就提到Sound Alert, is installing the alarms in a residential home。。。，所以这里所要填的词也应该是the alarms,选择答案D。
5. A. noise噪音 B. sound声音 C. music音乐 D. bell铃
分析：句子前半句是说a wide range of frequencies，所以发出的应是sound,因此答案选B。
5. Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be ___6___by humans.
6. A. watched观看 B. produced 产生 C. learnt学习 D. heard听到
分析：文章一直在讨论警报器、声音，因此很容易推断应该是被人听到。
6. Its a burst of white noise __7___ people say sounds like static on the radio, she says. Its life-saving potential is great.
7. A. where B. what C. that D. how
分析：A、B、D都不能构成语意上的连贯，而只有C，构成一个句型，强调句，its .that .这句话强调的是主语。去掉itsthat，剩下的完整句子就是：A burst of white noise，people say，sounds like static on the radio。
