Deborah Withington of Sound Alert says that the alarms use most of the frequencies that can be 56 by humans. “It’s a burst of white noise 57 people say sounds like static on the radio,” she says. “Its life-saving potential is great.”
She conducted an experiment in which people were filmed by thermal-imaging cameras trying to find their way out of a large 58 room. It 59 them nearly four minutes to find the door 60 a sound alarm, but only 15 seconds with one.
Withington studies h o w the brain 61 sounds at the university. She says that the 62 of a wide band of frequencies can be pinpointed more easily than the source of a narrow band. Alarms 63 the same concept have already been installed on emergency vehicles.
The alarms will also include rising or falling frequencies to indicate whether people should go up 64 down stairs. They were 65 with the aid of a large grant from British Nuclear Fuels.

完形填空
51.B 通過閱讀我們可以看出，空白后是一種裝置，用來改變當火災發(fā)生時找不到出口的危險境況，所以要表達“ 用……裝置”的意思，只能用介詞w i t h :帶著、 帶有。
52. A 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A 較為合適。
53. C 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答案應是C 。
54. D 我們知道該空的名詞應出現在前文，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。
55. B 句子前半句是說a wide range of frequencies,所以發(fā)出的應是s o u n d , 因此答案選B 。
56. D 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。
57. C 選項 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， 這句話強調的是主語。去 掉 it’s... that,剩下的完整句子就是“A burst of white noise, people say ( 插入語)，sounds like static on the radio”.
58. B 從上下文可以看出，是一個定語修飾r o o m , 表 示 “ 充滿了煙火的房間” ，選項 A 、 D 意思不吻合 ， C 作為定語，位置不應放在r o o m 前 ， 應放后面。只有B 合適。
59. C 顯然， 這個空是考察常用句型“it takes / took sb. some time to do sth” 。關鍵是確定動詞時態(tài)，從前面看都是過去時態(tài)，所以選擇C 。
60. C 逗號后面的one應該是指a sound alarm。從連詞but可以推斷， 前后應該意思相反，后面已有了with ,那么前句應是without。所以選擇C 。
61. A 句子主語是the brain ， 應 和 “ 處理”構成主謂關系，其他動詞均不合適。所以選擇A 。
62. D 解題關鍵是要看出句子中的主要結構是more...than,后面出現核心詞the source, 所以可以得出結論， 前面的名詞也應是source,這樣符合比較級用法，用來進行比較的事物必須具有可比性，所以選D 。
