　　警報器救盲人

　　如果看不見，那你可能會因找不到路而逃不出一幢失火樓房，那將是致命的。英國利茲市的一家公司發(fā)明的一種可指方向的警報器可能會把你引向出口。

　　聲音警報是一家由利茲大學設立的公司。該公司現(xiàn)在正在為位于薩莫塞特的一家盲人收容所和位于卡姆布雷亞的一家盲人資源中心安裝此種裝置。這種警報器發(fā)出的頻率范圍廣，使人腦可以判斷出聲音的來源。

　　該公司的戴博拉威星頓稱此種警報器使用人類可以聽到的大部分音頻。她說：它們是一種突出的頻譜連續(xù)而均勻的噪音。人們感覺它們聽上去就像是收音機發(fā)出的靜電噪聲，其在救人方面潛力巨大。

　　她進行了一次試驗。她讓人們在一所充滿濃煙的大屋子里設法找到出路，同時她用熱效應成像攝像機進行拍攝。在沒有警報器時，這些人用了近4分鐘才找到門，而在警報器的指引下，只用了15秒。

　　她在大學里對人腦如何處理聲音進行研究，并提出與波段窄的頻率相比，人們更容易發(fā)現(xiàn)波段寬的音響源。基于此理論的警報器已被應用于急救車上。

　　這種警報器也容納了音頻的升降，以指示人們上、下樓。這種設備是得到英國核燃料組織的大筆資助才開發(fā)成功的。[

　　Singing AlarmsCould Save the Blind

　　文章精讀：

　　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：通過閱讀我們可以看出，空格后是一種裝置，用它來改變當火災發(fā)生時找不到出口的危險境況，所以要表達用。。。。裝置意思的只能用介詞with，帶著、帶有。本句的意思是：利茲市一家公司發(fā)明的一種可指方向的聲音警報器能引導你到出口。

　　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：我們知道Sound Alert是一家公司的名字，從語意上判斷應該是由某人經營，因此選擇答案A較為合適。

　　3. A. slow慢的 B. deaf聾的 C. blind瞎的 D. lame瘸的

　　分析：這篇文章的核心內容就是有關盲人警報器的，而且后半句也提到a resource centre for the blind ，所以順理成章地得出結論應是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：我們知道該空的名詞應出現(xiàn)在前文，上一句就提到Sound Alert, is installing the alarms in a residential home。。。，所以這里所要填的詞也應該是the alarms,選擇答案D。

　　5. A. noise噪音 B. sound聲音 C. music音樂 D. bell鈴

　　分析：句子前半句是說a wide range of frequencies，所以發(fā)出的應是sound,因此答案選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觀看 B. produced 產生 C. learnt學習 D. heard聽到

　　分析：文章一直在討論警報器、聲音，因此很容易推斷應該是被人聽到。

　　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都不能構成語意上的連貫，而只有C，構成一個句型，強調句，its .that .這句話強調的是主語。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。
