Questions 28-31
·题型：SHORT ANSWER QUESTIONS 简答题
·题目解析：
题号 题目定位词 答案位置 题解
28 when, the furnace, constructed C段
第1行 注意题目要求ONE NUMBER ONLY只能是1个数字。题目均是由特殊疑问词when提问的，所以首先确定答案形式全都是数字，表时间或年代。建议考生可以把全文中所有表时间、年代的数字都画出来，这样就会一目了然，缩小了寻找答案的范围。然后利用顺序原则，细致比较原文中时间点附近的单词是否与题目中的关键词有同义替换表达，进而确定最佳答案。
题目问熔炉的建造时间。题目中the constructed与原文中C段第1行中的…and built a furnace对应：In 1638, Basil Brooke patented a steel-making process and built a furnace at This later became the property of Abraham 原文表明达比所买的那个熔炉是在1638年被修建的，所以年份1638是答案。
29 when, roads, leading to the bridge, completed E段
第5、6行 题目问通往桥的路何时修建完成。题目中定位词roads leading to the bridge completed 对应原文E段第5行的 roads continued for another two years, and the bridge was opened to traffic in 本句中的another two years(又两年)是建立在前文所说的1779年的基础之上的，所以年份1781是答案。
30 when, bridge closed to traffic E段
倒数第3行 题目问桥何时停止运输。题目中定位词bridge closed to traffic对应原文E段倒数第3行的Since 1934 the bridge has been open only to (自1934年以来，大桥一直只对行人开放。)只对行人开放，就表明停止了运输功能，所以年份1934是答案。
31 when, model of the bridge, built G段
第6行、7行 题目问桥的模型何时建成。根据定位词model of the bridge built找到原文G段第6至7行的So in 20XX a half-scale model of the bridge was (因此在20XX年，1:2比例的铁桥模型被建造。)很明显，年份20XX是答案。
题号 题目定位词 答案位置 题解
32 no written evidence, how, bridge was constructed F段
第1行 题目：没有书面证据来证明最初的铁桥是怎样被建造的。
原文：It has always been a mystery how the bridge was 铁桥到底是如何建造的始终是一个谜。
必要分析：原文中的It has always been a mystery与题目中的no written evidence都指没有证据的未解之进，两者陈述明显一致，互相符合，所以选TRUE。
33 Elias Martin, only F段
倒数1-4行 题目：伊莱亚斯·马丁的画是唯一一幅展现铁桥初建成的新貌的画作。
原文：In 1997 a small watercolour sketch by Elias Martin came to light in the Swedish capital, Although there is a wealth of early views of the bridge by numerous artists, this is the only one which actually shows it under 1997年瑞典人伊莱亚斯·马丁的一小幅水彩画现身瑞典首都斯德哥尔摩。虽然已有众多的艺术家描绘了桥梁初建成的情况，但却只有这件作品描绘了铁桥正在建设中的情景。
必要分析：题目中说此画展示了大桥新建成时的风貌，原文中说此画展示了大桥正在建设时的风貌。题目与文中事实陈述明显抵触，所以选FALSE。
34 painting, constructed, two banks C段
第1-5行 题目：图画展示了铁桥是从两岸建造起来的。
原文：Up until recently it had been assumed that the bridge had been built from both the picture clearly shows sections of the bridge being raised from a barge in the It contradicted everything historians had assumed about the 一直到最近始终有一种推测，桥梁建造工程可能是从河两岸同时开始……但这幅水彩画清晰地显示出，桥梁构件被河上的一艘驳船托起。这颠覆了所有历史学家先前的假设。
必要分析：原文中说水彩画中的信息颠覆了历史学家先前的假设，(包含了历史学家们所假设的铁桥是从两岸开始建造的观点)，题目与原文内容相抵触，所以答案为FALSE。
35 original bridge, model G段
第6-8行 题目：最初的铁桥及其模型花费了同样的时间去建造。
原文：So in 20XX a half-scale model of the bridge was built, in order to see if it could have been constructed in the way depicted in the 因此在20XX年，1:2比例的铁桥模型被建造，用来验证铁桥是否真的可以用水彩画中描绘的方式建成。
必要分析：题目是在比较最初的铁桥和桥的模型所花费的建造时间。原文提到了模型开始建造的时间，却没有提到建成的时间，所以无法比较是否花费了等量的时间去建造。就此话题，原文中没有任何信息，所以答案为NOT GIVEN。
36 Elias Martin, other paintings I段
第3-5行 题目：人们认为伊莱亚斯·马丁还有其他关于大桥的图画。
原文：It had been drawn by a Swedish artist who lived in London for 12 years and … but perhaps the other sketches still exist 这幅水彩画由一位旅居伦敦12年的瑞典画家所绘……有可能其他的草图仍然流藏在某个地方。
必要分析：题目中have made other paintings of the bridge与原文中perhaps the other sketches still exist somewhere都指可能还有其他有关该桥的图画，两者陈述明显一致，互相符合，所以答案为TRUE。剑桥雅思G类真题

37 why, bridge, across the River Severn D段
第1、2行 题目：大桥需要横跨塞文河的原因
原文：
had the idea of building a bridge over the Severn, as ferrying stores of all kinds across the 他的儿子，亚伯拉罕·达比二世，作为铸铁业的先锋人物，早就有在塞文河上建造一座大桥的想法，以便把各种货物运过河对岸。
必要分析：原文讲述了亚伯拉罕·达比二世建造大桥的原因在于运送货物，很明显这就是题目中所指的原因。所以37题的信息来自于D段，答案为D。
38 a method used to raise money E段
第6、7行 题目：用来筹集资金建造铁桥的方法
原文：Abraham Darby III funded the bridge by commissioning paintings and 亚伯拉罕·达比三世利用绘画和雕刻的佣金来资助桥梁修建……
必要分析：题目中money与原文中fund对应;原文讲了建桥资金的来源，所以38题的信息来自于E段，答案为E。
39 why Coalbrookdale, attractive, iron makers C段
第5-8行 题目：科尔布鲁克代尔地区对铁制造者有吸引力的原因
原文：This led to cheaper, more efficient ironmaking from the abundant supplies of coal, iron and limestone in the 当地有丰富的煤矿、铁矿和石灰石资源，这使得炼铁的成本降低了， 而且效率更高。
必要分析：此题较难。没有非常明显的同义替换。通过上下文我们了解到，亚伯拉罕·达比搬家的原因就在于他发现来源于煤的焦炭可以替代木炭成为更经济的炼铁燃料。而科尔布魯克代尔地区还有着很多的资源优势可以使炼铁变得成本更低而效率更髙。很明显，这些都是该地区吸引制铁者的原因。文中ironmaking对应题目中的iron makers;the area指的便是Coalbrookdale。39题的信息来自于C段，答案为C。
40 how, sections, were connected H段
第3、4行 题目：铁桥的各部分是如何相互连接的?
原文：Instead it was fitted together using a complex system of joints normally used for 与当今的铁制桥梁不同，这座桥的各构件之间既不是焊接而成也不是用螺栓固定，而是运用了一种通常用于搭建木质结构的复杂连接工艺。
必要分析：题目中的were connected与原文中的it was fitted normally used for wood相对应。40题的信息来自于H段。答案为H。

雅思g类真题 第4篇
剑桥雅思阅读原文：You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1
Hearing impairment or other auditory function deficit in young children can have a major impact on their development of speech and communication, resulting in a detrimental effect on their ability to learn at This is likely to have major consequences for the individual and the population as a The New Zealand Ministry of Health has found from research carried out over two decades that 6-10% of children in that country are affected by hearing
A preliminary study in New Zealand has shown that classroom noise presents a major concern for teachers and Modern teaching practices, the organization of desks in the classroom, poor classroom acoustics, and mechanical means of ventilation such as air-conditioning units all contribute to the number of children unable to comprehend the teacher’s Education researchers Nelson and Soli have also suggested that recent trends in learning often involve collaborative interaction of multiple minds and tools as much as individual possession of This all amounts to heightened activity and noise levels, which have the potential to be particularly serious for children experiencing auditory function Noise in classrooms can only exacerbate their difficulty in comprehending and processing verbal communication with other children and instructions from the
Children with auditory function deficit are potentially failing to learn to their maximum potential because of noise levels generated in The effects of noise on the ability of children to learn effectively in typical classroom environments are now the subject of increasing The International Institute of Noise Control Engineering (I-INCE), on the advice of the World Health Organization, has established an international working party, which includes New Zealand, to evaluate noise and reverberation control for school
While the detrimental effects of noise in classroom situations are not limited to children experiencing disability, those with a disability that affects their processing of speech and verbal communication could be extremely The auditory function deficits in question include hearing impairment, autistic spectrum disorders (ASD) and attention deficit disorders (ADD/ADHD).
Autism is considered a neurological and genetic life-long disorder that causes discrepancies in the way information is This disorder is characterized by interlinking problems with social imagination, social communication and social According to Janzen, this affects the ability to understand and relate in typical ways to people, understand events and objects in the environment, and understand or respond to sensory Autism does not allow learning or thinking in the same ways as in children who are developing Autistic spectrum disorders often result in major difficulties in comprehending verbal information and speech Those experiencing these disorders often find sounds such as crowd noise and the noise generated by machinery painful and This is difficult to scientifically quantify as such extra-sensory stimuli vary greatly from one autistic individual to But a child who finds any type of noise in their classroom or learning space intrusive is likely to be adversely affected in their ability to process
The attention deficit disorders are indicative of neurological and genetic disorders and are characterized by difficulties with sustaining attention, effort and persistence, organization skills and Children experiencing these disorders find it difficult to screen out unimportant information, and focus on everything in the environment rather than attending to a single Background noise in the classroom becomes a major distraction, which can affect their ability to
Children experiencing an auditory function deficit can often find speech and communication very difficult to isolate and process when set against high levels of background These levels come from outside activities that penetrate the classroom structure, from teaching activities, and other noise generated inside, which can be exacerbated by room Strategies are needed to obtain the optimum classroom construction and perhaps a change in classroom culture and methods of In particular, the effects of noisy classrooms and activities on those experiencing disabilities in the form of auditory function deficit need thorough It is probable that many undiagnosed children exist in the education system with ‘invisible’ Their needs are less likely to be met than those of children with known
The New Zealand Government has developed a New Zealand Disability Strategy and has embarked on a wide-ranging consultation The strategy recognizes that people experiencing disability face significant barriers in achieving a full quality of life in areas such as attitude, education, employment and access to Objective 3 of the New Zealand Disability Strategy is to ‘Provide the Best Education for Disabled People’ by improving education so that all children, youth learners and adult learners will have equal opportunities to learn and develop within their already existing local For a successful education, the learning environment is vitally significant, so any effort to improve this is likely to be of great benefit to all children, but especially to those with auditory function
A number of countries are already in the process of formulating their own standards for the control and reduction of classroom New Zealand will probably follow their The literature to date on noise in school rooms appears to focus on the effects on schoolchildren in general, their teachers and the hearing Only limited attention appears to have been given to those students experiencing the other disabilities involving auditory function It is imperative that the needs of these children are taken into account in the setting of appropriate international standards to be promulgated in

剑桥雅思阅读答案解析Question 1
答案：
H
关键词：
national policy
定位原文: H段第1句“The New Zealand Government…”
解题思路: 这一段的首句就以一种叙事口吻向考生交代了新西兰全国上下正在开展的一场为残疾人服务的战略，该句含义为“新西兰政府已经制定出一项‘新西兰残疾人事业发展战略’，并开始进入广泛咨询意见的阶段。”此外，在该段其他语句中也提到the strategy , Objective to 等信息，非常符合题干中account一词的含义。
Question 2
答案：
C
关键词：
global team
定位原文：
C段最后一句“The International Institute of…”
解题思路：
这句含义为“在世界卫生组织的建议下，国际噪声控制工程学会(I-INCE)成立了一个国际工作小组来”，这句话中international可以对应题干中的global, 而working party可以对应team。这是对应关系非常明显的一道题目。
Question 3
答案：
B
关键词：
hypothesis, reason, growth in classroom noise
定位原文：
B段第3句“Nelson and Soil have also ”
解题思路：
在该段首句中就出现了classroom noise这个词，因此该段有可能就是本题的对应段落。在接下来的叙述Nelson and Soil have also 中，suggest一词可以对应题干中的 hypothesis 后一句中的This all amounts to heightened activity and noise levels，与题干中的 one reason相对应。
Question 4
答案：
I
关键词：
worldwide regulations
对应原文：
I 段最后一句“It is imperative that the needs…”
解题思路：
全文只有此句中提及国际标准，含义为“今后在制定和颁布国际标准时，必须把这些孩子的需求考虑进去。”句中的international应题干中的worldwide，standards对应题干中的regulations。这道题属于考点明晰、词语替换幅度也不大的简单题型。
Question 5
答案：
D
关键词：
medical conditions，more at risk
定位原文：
D段第1句“… those with a disability that affects…”
解题思路：
该段第一句话就明确说出了题干中的意思。While引导让步状语从句，不必细看，直接跳到主句，those with a disability that affects their processing of speech and verbal communication could be extremely vulnerable，含义为“那些在语言沟通方面有障碍的孩子们显然是噪音的更大受害者”; disability that affects their processing of speech and verbal communication对应题干中的medical conditions, extremely vulnerable对应题干中的more at risk。此外，下文罗列出的hearing impairment, autistic spectrum disorders and attention deficit disorders可与a list of medical conditions相对应 。
Question 6
答案: A
关键词: proportion, with auditory problems
定位原文: A段最后一句“The New Zealand…”
解题思路：
此题相对来说比较简单，看到题干中proportion“比例”一词，马上扫描文章，寻找带有百分比的段落。显然，只有A段最后一句带有明显的百分比。接着需要验证百分比所在的句子是否在讲新西兰听力残障患儿的比例，然后确认选择就可以了。该句中affected by hearing loss与题干中的with auditory problems相对应。
Question 7
答案：
two decades
关键词：
For what period of time, been studied
定位原文：
A段最后一句“The New Zealand Ministry of Health…”
解题思路：
在这句话中，有的考生会认为答案是over two decades,他们会把 over翻译成“超过”。实际上，在雅思阅读中，over大多数情况下是 during的意思，表示“在某段时间内”。况且此处若填over two decades，也不符合题目要求。故正确答案为two decades，注意复数形式。
Question 8
答案: crowd (noise)
关键词: machinery noise, autism
定位原文: E段倒数第3句“Autistic…”
解题思路: 此题的难度就是对应点和上一题离得太远，不太好找。但是考生如果能循着autism(自闭症)这个词，同时再留意一下它的变形，如 autistic, 就能快速定位到E段首句Autism这个词，然后找到such as和the noise generated by machinery。这样就不难推出正确答案就是和the noise generated by machinery并列的 crowd noise。
Question 9
答案: invisible (disabilities/disability)
关键词: term, schoolchildren which have not been diagnosed
定位原文: G段倒数第2句“It is…”
解题思路：
根据顺序原则，可以大概判断出此题应该在E段以后的段落出现，而term一词是“术语”的意思，一般对应文中特殊字体或加引号的词。按这个思路找下去，很快可以找到G段倒数第二行的引号。
接下来只需判断一下在引号周围的内容是否是在谈which have not been diagnosed。文中提到…many undiagnosed children exist in the education system with‘ invisible’disabilities，undiagnosed一词即使不认识也可以根据构词法利用前缀un猜测为“未经的”，完全可以与题目have not been diagnosed对应。故正确答案为invisible (disabilities/disability )。
Question 10
答案: Objective 3
关键词：
What part, New Zealand Disability Strategy, equal opportunity
定位原文：
H段第3句“Objective 3…”
解题思路: 首先利用大写New Zealand Disability Strategy定位到H段，然后开始寻找equal opportunity，很快将目标锁定在第六行末尾处。读完这个词所在的整句话，不难发现是这个战略中的Objective 3专门针对平等机会问题。故正确答案为Objective 3。
Question 11 & Question 12
答案: A C (in either order)
关键词: factors contributing to classroom noise
定位原文: B段，参见详细的解题思路解析
解题思路: 选项A：当今教学方式——B段第二行出现的Modem teaching practices以及第五行出现的 trends in 都可以对应该选项。故选项A正确;选项B：走廊回音——没有提到，不要因为B段第三行提到poor classroom acoustics就联想是这个选项，这只是指教室中的音响效果差;选项C：制冷系统 ——第三行中提到…mechanical means of ventilation such as air-conditioning, 指空调通风口产生的噪音。故选项C正确;选项D：班级学生数量太多——完全未提及;选项E：老师声音洪亮——文中只是提到老师，但是没有说老师声音洪亮;选项F：操场游戏——完全没有提到。
Question 13
答案：
C
关键词：
overall purpose
定位原文：
I 段
解题思路：
题目：作者写本文的主要目的是什么 比较应对听觉障碍的不同措施;
为过分嘈杂的学习环境提供解决方法;C提高对听觉障碍儿童现状的关注;D把新西兰作为其他国家学习的榜样。首先排除D,因为I段前两句话表明新西兰实际上要效仿其他国家，而不是被其他国家效仿，这个选项与文中信息矛盾。接着I段提到：Only limited attention appears to have been given to those students experiencing the other disabilities involving auditory function It is imperative that the needs of these children are taken into account…这句话明确表示本文的目的是让更多人关注听觉障碍儿童的现状。故正确答案是C。

Keep a watchful eye on the bridge
Most road and rail bridges are only inspected visually, if at Every few months, engineers have to clamber over the structure in an attempt to find problems before the bridge shows obvious signs of Technologies developed at Los Alamos National Laboratory, New Mexico, and Texas A&M University may replace these surveys with microwave sensors that constantly monitor the condition of
“The device uses microwaves to measure the distance between the sensor and the bridge, much like radar does,” says Albert Migliori, a Los Alamos physicist “Any load on the bridge – such as traffic induces displacements, which change that distance as the bridge moves up and ” By monitoring these movements over several minutes, the researchers can find out how the bridge Changes in its behaviour can give an early warning of
The Interstate 40 bridge over the Rio Grande river in Albuquerque provided the researchers with a rare opportunity to text their Chuck Farrar, an engineer at Los Alamos, explains: “The New Mexico authorities decided to raze this bridge and replace We were able to mount instruments on it, test it under various load conditions and even inflict damage just before it was ” In the 1960s and 1970s, 2500 similar bridges were built in the They have two steel girders supporting the load in each Highway experts know that this design is “fracture critical” because a failure in either girder would cause the bridge to
After setting up the microwave dish on the ground below the bridge, the Los Alamos team installed conventional accelerometers at several points along the span to measure its They then tested the bridge while traffic roared across it and while subjecting it to pounding from a “shaker”, which delivered precise punches to a specific point on the

The initial, crude analysis of the bridge"s behaviour, based on the frequency at which the bridge resonates, did not indicate that anything was wrong until the flange was But later the data were re-analysed with algorithms that took into account changes in the mode shapes of the structure – shapes that the structure takes on when excited at a particular These more sophisticated algorithms, which were developed by Norris Stubbs at Texas A&M University, successfully identified and located the damage caused by the initial

How did the traditional way to prevent damage of the bridges before the invention of new monitoring system?
bridges has to be tested in every movement on two points
bridges has to be closely monitored by microwave devices
bridges has already been monitored by sensors
bridges has to be frequently inspected by professional workers with naked eyes
How do the new microwave monitors find out the problems of bridges?
by changeling the distance between the positions of devices
by controlling the traffic flow on the bridges
by monitoring the distance caused by traffic between two points
by displacement of the several critical parts in the bridges
Why did the expert believe there is a problem for the design called “fracture critical”?
Engineers failed to apply the newly developed construction materials
There was not enough finance to repair the bridges
the supporting parts of the bridges may crack and cause the bridge to fail
There were bigger traffic load conditions than the designers had anticipated
Defect was not recognized by a basic method in the beginning
until the mid of faces of bridges has fractures
until the damage appears along and down to the flanges
until the points on the road have been punched
until the frequency of resonates appears disordered
