　　警報(bào)器救盲人

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

　　聲音警報(bào)是一家由利茲大學(xué)設(shè)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(bào)器發(fā)出的頻率范圍廣，使人腦可以判斷出聲音的來(lái)源。

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

　　她進(jìn)行了一次試驗(yàn)。她讓人們?cè)谝凰錆M濃煙的大屋子里設(shè)法找到出路，同時(shí)她用熱效應(yīng)成像攝像機(jī)進(jìn)行拍攝。在沒(méi)有警報(bào)器時(shí)，這些人用了近4分鐘才找到門(mén)，而在警報(bào)器的指引下，只用了15秒。

　　她在大學(xué)里對(duì)人腦如何處理聲音進(jìn)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(bào)器已被應(yīng)用于急救車(chē)上。

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

　　解析標(biāo)題：

　　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(guò)閱讀我們可以看出，空格后是一種裝置，用它來(lái)改變當(dāng)火災(zāi)發(fā)生時(shí)找不到出口的危險(xiǎn)境況，所以要表達(dá)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(bào)器能引導(dǎo)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(yǔ)意上判斷應(yīng)該是由某人經(jīng)營(yíng)，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(nèi)容就是有關(guān)盲人警報(bào)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(jié)論應(yīng)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(yīng)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(yīng)該是the alarms,選擇答案D。

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

　　分析：句子前半句是說(shuō)a wide range of frequencies，所以發(fā)出的應(yīng)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(chǎn)生 C. learnt學(xué)習(xí) D. heard聽(tīng)到

　　分析：文章一直在討論警報(bào)器、聲音，因此很容易推斷應(yīng)該是被人聽(tīng)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(gòu)成語(yǔ)意上的連貫，而只有C，構(gòu)成一個(gè)句型，強(qiáng)調(diào)句，its .that .這句話強(qiáng)調(diào)的是主語(yǔ)。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。

　　7. She conducted an experiment in which people were filmed by thermalimaging cameras trying to find their way out of a large __8___ room.

　　A. smoked煙熏的 B. smoke-filled

　　C. filled with smoke D. smoke-filling使。。。煙火彌漫的

　　分析：從上下文可以看出，是一個(gè)定語(yǔ)修飾room，表示充滿了煙火的房間

　　答案A，D意思不吻合，C作為定語(yǔ)，位置不應(yīng)放在room前，應(yīng)放后面。只有B才符合句子。

　　8. It __9___ them nearly four minutes to find the door __10____ a sound alarm, but only 15 seconds with one.

　　9. A. has taken B. takes C. took D. will take

　　分析：顯然，這個(gè)空是考察常用句型：it takes / took sb some time to do sth.關(guān)鍵是確定動(dòng)詞時(shí)態(tài)，從前面看都是過(guò)去時(shí)態(tài)，所以選擇C。

　　10. A. on B. near C. without D. from

　　分析：逗號(hào)后面的one應(yīng)該是指a sound alarm，從連詞but可以推斷，前后應(yīng)是意思相反，后面已有了with, 那么前句應(yīng)是without, 所以選擇C。讀讀意思很通順。

　　9. Withington studies how the brain __11____sounds at the university.

　　A processes B. produces

　　C. possesses D. proceeds

　　分析：句子主語(yǔ)是the brain應(yīng)和處理構(gòu)成主謂關(guān)系，而其它動(dòng)詞均不合適，所以選擇A。

　　10. She says that the __12___ of a wide band of frequencies can be pinpointed more easily than the source of a narrow band.

　　12. A. feature特征 B. quality質(zhì)量、素質(zhì)

　　C. diagram圖解 D. source來(lái)源

　　分析：解題關(guān)鍵是要看出句子中主要結(jié)構(gòu)是morethan, 后面出現(xiàn)核心詞the source, 所以可以推斷得出結(jié)論，前面的名詞也應(yīng)是source.這樣符合比較級(jí)用法，用來(lái)進(jìn)行比較的事物必須具有可比性。所以選D。

　　11. Alarms ___13____ the same concept have already been installed on emergency vehicles.

　　A. basis on B. base on C. basing on D. based on

　　分析：Alarms是主語(yǔ)，have already been installed是謂語(yǔ)，所以要填的動(dòng)詞應(yīng)該是分詞形式，做定語(yǔ)，所以四個(gè)答案只有D可能, be based on以。。。為基礎(chǔ)。

　　12. The alarms will also include rising or falling frequencies to indicate whether people should go up __14___ down stairs.

　　A. or B. and C. but D. otherwise

　　分析：根據(jù)前半句的rising or falling frequencies，可以看出這句話也應(yīng)該填連接詞or, 表示或者。

　　13. They were __15__ with the aid of a large grant from British Nuclear Fuels.

　　A. developed B. determined C. discovered D. delivered

　　分析：主語(yǔ)they 代指the alarms, 后半句是說(shuō)這種設(shè)備得到大筆資助。根據(jù)上下文，資助的目的是為了開(kāi)發(fā)，所以應(yīng)該選A。

　　14.A 根據(jù)上半句中的rising or falling frequencies,這里應(yīng)填入or, 與上半句表達(dá)的意思相一致。音頻升高表示上樓，音頻降低表示下樓。

　　15. A. 首先確定主語(yǔ)They指的是第一句中的主語(yǔ)The alarms,后半句說(shuō)這種設(shè)備得到大筆資助，根據(jù)上文內(nèi)容，我們知道資助的目的是開(kāi)發(fā)這種alarms,所以應(yīng)該選擇developed。
