9、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。I!她实行了一次试验。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实行拍摄。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实行研究,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。 解析标题:Singing (唱歌的)Alarms (警报器)Could (能够)Save (挽救)

10、the Blind (定冠词 + 形容词,表示一类人,盲人)文章精读:1>. If you cannot see (看见) ,you may not be able to find(找到) your way out of (出来) a burning (正在着火的) building (大楼) and that could be (可能是) fatal (致命 的)。2>. A company in Leeds (英国利兹市) could change (改变) all (所有的) that (代词,指前一句所表达的内容)_1_directional (定向的) sound ala

11、rms (声音警报器) capable of (有水平的) guiding (引导) you to the exit (出口)。A. without B. with C. having D. selling分析:通过阅读我们能够看出,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 (声音警报器) ,a company (逗号前面是公司名 字) _2_ the University of

12、 Leeds(利兹大学) ,isinstalling (安装) the alarms in a residential home (收容所) for _3_ people in Sommerset and a resource centre(资源中心) for the blind (盲人) in Cumbria.A. run (经营) by B. changed (改变) byC. decorated (装修) by D. criticized (批评) 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,所以选择答案 A较为合适。3. A. slow

13、 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相关盲人警报器的,而且后半句 也提到 a resource centre (资源中心) for the blind (盲人), 所以顺理成章地得出结论应是 C.4>. _4_ produce (产生) a wide range (广的范围) of frequencies (频率) that (引导定语从句) enable (使 能够) the brain to determine (决定) where the _5_ is coming from.4. A. Alarms B. Ala

14、rm 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 in stalli ng the alarms in a reside ntial 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 (广的范围) of freque ncies(频率),所以发出的应是sou nd,所以答案选B.5>. Deborah Withington (人名)

15、 of Sound Alert says that the alarms use (使用) most of (绝大部分的) the frequencies that can be _6_by humans (人)。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,所以很容易推断应该是被 人听到。6>. "It's a burst (突然发出的) of white noise (连续而均 匀的声音) _7_ people say sounds like static(静电噪音)

16、on the radio (收音机里) ,"she says. "Its life-saving(挽救生命的) potential (潜力) 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,it's 。that。这句话强调的是主语。去掉 it ' sthat,剩下的完整句子就是:A burst of white noise ,people say (插入语), sounds like static on the radio.7>

17、. She conducted (实行) an experiment (实验) in which (引导定语从句,在这项实验中) people were filmed (被拍摄) by thermal imaging (热效应成像) cameras (照相机)trying tofind their way out of(找到从出去的路)a large _8room.A. smoked 烟熏的 B. smoke-filledC. filled with smoke D. smoke-filli ng使烟火弥漫的分析:从上下文能够看出,是一个定语修饰room,表示"充满了烟火的房间&qu

18、ot;答案A, D意思不吻合,C作为定语,位置不应放在room前,应放 后面。只有 B 才符合句子。8>. It _9_ them nearly(几乎) four minutes to findthe door _10 a sound alarm,but only 15 seconds(秒)with one.9. A. has taken B. takes C. took D. will take 分析:显然,这个空是考察常用句型: it takes / took sb sometime to do sth. 关键是确定动词时态,从前面看都是过去时态,所以 选择 C.10. A. on

19、B. near C. without D. from分析:逗号后面的 one 应该是指 a sound alarm ,从连词 but 能够 推断,前后应是意思相反,后面已有了 with, 那么前句应是 without, 所以选择C.读读意思很通顺。9>. Withington studies how (如何) the brain (大脑) _11sounds at the university.A processes (处理) B. produces (产生)C. possesses (拥有) D. proceeds (前进)分析:句子主语是 the brain 应和"处理&q

20、uot; 构成主谓关系,而其它 动词均不合适,所以选择 A.10>. She says that the _12_ of a wide band of frequencies (波段宽的频率) can be pinpointed (精确地确定) more easily than the source of a narrow band (窄波段)。12. A. feature 特征 B. quality 质量、素质C. diagram 图解 D. source 来源分析:解题关键是要看出句子中主要结构是morethan,后面出现核心词 the source, 所以能够推断得出结论,前面的名

21、词也应是 source. 这样符合比较级用法,用来实行比较的事物必须具有可比性。 所以选 D.11>. Alarms _13 the same concept (观点、概念) havealready been installed (已经被安装) on emergency vehicles (急救车)。A. basis on B. base on C. basing on D. based on分析: Alarms 是主语, have already been installed 是谓语, 所以要填的动词应该是分词形式,做定语,所以四个答案只有D可能,be based on 以为基础。12

22、>. The alarms will also include (包括) rising (上升) or falling (下降) frequencies to indicate (指示) whether (是否) people should go up _14_ down stairs.A. or B. and C. but D. otherwise分析:根据前半句的 rising or falling frequencies,能够看出这句话也应该填连接词 or, 表示或者。13>. They were _15_ with the aid of a large grant from

23、 British Nuclear Fuels.A. developed B. determined C. discovered D. delivered分析:主语 they 代指 the alarms, 后半句是说这种设备得到大笔 资助。根据上下文,资助的目的是为了开发,所以应该选 A.14.A 根据上半句中的 rising or falling frequencies ,这里应 填入 or, 与上半句表达的意思相一致。音频升高表示上楼,音频降低表 示下楼。15. A. 首先确定主语 They 指的是第一句中的主语 The alarms , 后半句说这种设备得到大笔资助,根据上文内容,我们知道资助的目 的是开发这种 alarms ,所以应该选择 developed.
