新东方四六级考前内部串讲讲义阅读理解的部分

　　综述

　　作为一种基本的命题形式，阅读理解一直都在四级考试中占有重要的位置。一般地，我们应该有这样的思考：

　　第一，具备一定的词汇量和难句分析理解能力

　　1、单词量是体现阅读水平最重要的尺度之一。大量的单词，一方面能够帮助我们清晰把握文章准确的含义，另一方面又能给予相当的速度保证。但是，从这两年最新的考试情况来看，我们发现许多阅读理解中的许多涉及的许多词汇要求考生全面了解这个词的完整意义，尤其是单词生僻的含义。如果复习时缺乏这种认识，必然导致做题时捉襟见肘、处处被动。如，further除作形容词、副词外还可作动词表示增进、促进company除公司之外还表示伙伴之意。

　　当然认词是掌握词汇最基本的要求，对于想取得高分的同学来说，光是知道一个词的词义是远远不够的，还必须知道这个词与其他词，尤其是其同义词和近义词的区别。

　　2、长难句一般是指结构复杂难以理解的句子，也有一些其实结构并不复杂，但因为句子很长也很容易让人困惑，大大增加我们理解的难度，成为我们获取高分的拦路虎。因此，复习时一定要重视长难句的分析和理解。

　　第二，具备正确的阅读方法

　　提高阅读理解能力固然有赖于考生平时的多阅读和多积累。但是，阅读理解能力的提高也是有一定方法可循的，为此我们提出通过逻辑关系来阅读。英文是非常讲究逻辑关系的语言。而逻辑关系并不抽象，它深深渗透到了文章的各个角落，而且这些逻辑关系同时也是文章语句得以联系和组合的最深层次的原因。逻辑关系散布在文章的句子内部、句句之间、以及段落之间。最基本的逻辑关系有以下几种：

　　1、因果关系：as a result ，therefore，hence，consequently，because, for, due to, hence, consequently等等。

　　2、并列、递进关系：and, or, then，in addition，besides，in other words，moreover等等

　　3、转折关系：however，but, yet, in fact等等。

　　这些我们其实已经很熟悉的逻辑提示词在文章中起的效果，并非仅仅是衔接文章的句子，从阅读的角度来看，其实同时在给我们某种提示，告诉我们哪些句子是有效信息，相对重要的信息，哪些信息是相对不重要的信息，因为我们在处理文章的时候，有一条清晰的思路，你不是为了完整翻译文章而进行阅读，而是为了获取主旨来阅读。

　　比如因果关系。原因和结果两句话同时出现的时候，我们更关心的是结果，而不是原因，原因的存在只是为了使得文章的论证更加有说服力，让读者更加相信这个结果存在的合理性和必然性，所以，从获取句子主旨这个阅读的终极目标来看，原因就变得相对不重要了，我们可以把表示原因的句子直接跳开，保留体现结果意义的句子来阅读和把握。

　　2005年6月四级阅读理解真题中就有这样的一些句子：

　　And consumers would wait up to a decade to gain any benefits, because drilling could begin only after much bargaining over leases, environmental permits and regulatory review.

　　我们发现了一个非常明显的逻辑提示词because,它之后牵引出的是具体原因的分析，所以，从获取文章main idea的角度来看，完全可以把其后的信息全部删除。

　　转折关系也是如此。转折词汇在句子衔接处出现，说明作者陈述的内容的逻辑主旨发生了变化，因此，转折逻辑词之前的信息就变得不重要了，简单的处理方法是可以仅阅读转折词之后的信息。

　　例如，He has argued that tapping ANWRs oil would help ease Californias electricity crisis and provide a major boost to the countrys energy independence. But no one knows for sure how much crude oil lies buried beneath the frozen earth, with the last government survey, conducted in 1998, projecting output anywhere from 3 billion to 16 billion barrels.

　　再例：

　　It did not test the claims, but compared them to labeling guidelines set by the International Standards Organization in September, 1999.

　　相应地，并列递进关系，意味着并列、和递进类的逻辑提示词前后衔接的信息属于并列和递进的关系，从主旨的体现上前后没有发生变化，而更多的体现为前后句子主旨的相似性，所以我们选择其中的一半进行阅读，保证了阅读质量的基础上，极大地提高了阅读速度。

　　第三，培养良好的阅读习惯

　　良好的阅读习惯，对于要以较快的速度从大量材料中捕捉主旨信息的阅读能力的提高起到很大的影响，为此，从教学实践中出现的一些代表性的问题，我们提出一些建议。

　　1、成组视读。成组视读阅读的是一个个的意群，这样，一方面阅读的速度可高于逐字阅读的好几倍，另一方面很容易把每个意群中的关键词串起来理解。因此，建议考生在开始平时应有意识地进行训练。

　　2、单次通读。所谓单次通读就是要尽量减少阅读文章反复的次数，尽量做到在第一次通读的过程中就能够获取文章的主旨。相当多的学生对阅读已经产生心理定势，即认为自已第一遍肯定读不懂，因此反复多遍，习惯于在不加限定的时间内，对一小块文章精雕细琢，浪费了很多时间。

　　3、直接译读。在阅读过程中，应该将所读的句子直接进行理解，而不应该不断地进行逐词逐句的翻译，通过译成母语来辅助理解。这样，就把阅读理解转化成了英译汉的工作，影响了阅读速度，同时限制了对文章关键信息的串联。

　　总的来说，从最新的考试题来看，阅读理解部分难度与往年基本持平。对于将在下一次试行的新四级考试，考生们也不用过分担心，因为测试的重点依然体现在考生对文章阅读本身的掌握是否得当。因此，平时的练习还是要立足现有的真题，培养正确的阅读方法和阅读习惯。许多考生把注意力过分地集中在题目上，固然我们相信阅读理解确实是需要解题技巧，但是相对而言，如果想从阅读能力上真正有所提升，还是要首先学会真正有效地进行阅读，这样往往会起到事半功倍的效果。

　　具体来说，我们在考试前的阅读复习可以加强如下几个部分。

　　1

　　第一部分 长难句的理解

　　长难句的明显特点就是句子比较长，一个句子往往有三、四行，甚至一个句子就是一段。许多应试者在阅读时经常会陷入一个很长的句子中，不知道它到底讲了些什么。长难句之所以长，主要有下面几个原因：

　　1. 从句较长：一个主句带多个从句，从句中又有从句。

　　应对方法：首先找到主句的主体部分(即主语、谓语和宾语)，再确定从句的主体部分，如果从句中还有从句，在确定下面一层从句的主、谓、宾。注意阅读时一层一层进行，先把同一层次的内容看完，再看下一层次的内容。

　　2. 插入成分较长：插入语的出现有明显标志：用双破折号与主句隔开或者用双逗号与主句隔开。

　　应对方法：读句子时，先不要理会插入语，先把主句的意思看完。然后再看插入部分。

　　例如： Today, stepladders carry labels several inches long that warn, among other things, that you might surprise! fall off.

　　这个句子的阅读顺序应该是：第一层stepladders carry labels several inches long that，第二层是that warn that you might fall off，最后再看两个插入的部分among other things和surprise!

　　3. 分词状语、独立主格结构的干扰：分词状语就是指用doing或done引导的伴随状语、原因状语等;独立主格结构有时由with引导，看似主谓结构，但实际上并没有真正的谓语部分。

　　应对方法：主句最重要的特征就是有完整的主谓结构，尤其是独立的谓语部分。如果没有独立的谓语部分，那它就不是句子，而是分词短语或者独立主格结构。

　　在实际的阅读过程中，我们常常会碰到包含上面三种情况的超复杂句子，即：一个句子中既有从句又有插入成分，还有分词状语或者独立主格结构。阅读这种句子的正确方法是：抓住独立的谓语部分从而区别出主句和分词状语，再根据从句的连接词(有时无连接词)区分主句和从句，层层理解，插入语插在哪个层次中就放在哪个层次中理解。

　　以下附上一些热点的难句链接，供大家练习参考：

　　1 The producers of packaged products argue strongly against changing sizes of packages to contain even weights and volumes, but no one in the trade comments unfavorably on the huge costs incurred by endless changes of package sizes, materials, shape, art work, and net weights that are used for improving a products market position.

　　2 A study of drugstore(杂货店)and supermarket shelves will convince any observer that all possible size and shapes of boxes, jars, bottles, and tins are in use at the same time and, as the package journals show, week by week, there is never any hesitation in introducing a new size and shape of box or bottle when it aids in product differentiation.

　　3 Dying patients especially ---who are easiest to mislead and most often kept in the dark---can then not make decisions about the end of life: about whether or not they should enter a hospital, or have surgery; about where and with whom they should sped their remaining time; about how they should bring their affairs to a close and leave.

　　4 I think that after I spent my time under water, the most important thing that I came back with was the realization that it is now possible for men to live permanently where once they could not even venture for a second, and this is of tremendous importance because if you realize what it means that advancing technology now has peeled off a layer of ocean water 200meters thick and it opens up vast new lands and resources and knowledge which is only 200meters away and which has been there waiting for us for centuries.

　　5 The manufacturer who increases the unit price of his product by changing his package size to lower the quantity delivered can, without undue hardship, put his product into boxes, bags, and tins that will contain even 4-ounce, 8-ounce, one-pound, two-pound quantities of breakfast foods, cake mixes, etc.

　　第二部分 内在逻辑关系理解

　　一篇文章各段落之间及各句子之间都存在着一定的逻辑关系，正确理解这种逻辑关系有助于考生做出快速而准确的选择，提高做题的正确率。

　　这种类型的考题主要是考查考生对文章逻辑结构的理解，要求考生综合运用各方面的知识如：语法、词汇、语感、逻辑结构等进行分析判断。只理解个别句子的含义是远远不够的，还必须把上、下文的意思联系起来，弄清前后句之间、各段落之间的逻辑关系，从语篇的角度上对文章进行整体性的理解、分析、判断。

　　常见的连接词和过渡词能表征上下文内在逻辑关系：

　　1 前后意思一致：in other words, that is to say, namely, this means, likewise

　　2 并列平行：and, or, also, too, besides, another

　　3 递进：in addition to, adding to, moreover, furthermore

　　Passage 1

　　Is there enough oil beneath the Arctic National Wildlife Refuge to help secure Americas energy future ? President Bush certainly thinks so . He has argued that tapping ANWRs oil would help ease Californias electricity crisis and provide a major boost to the countrys energy independence . But no one knows for sure how much crude oil lies buried beneath the frozen earth . with the last government survey , conducted in 1998, projecting output anywhere from 3 billion to 16 billion barrels .

　　The oil industry goes with the high end of the range , which could equal as much as 10% of U.S. consumption for as long as six years . By pumping more than 1 million barrels a day from the reserve for the next two three decades, lobbyists claim, the nation could cut back on imports equivalent to all shipments to the U.S. from Saudi Arabia. Sounds good. An oil boom would also mean a multibillion-dollar windfall(意外之财)in tax revenues, royaltiesand leasing fees for Alaska and the Federal Government. Best of all , advocates of drilling say , damage to the environment would be insignificant . We ve never had a document case of oil rig chasing deer out onto the pack ice . says Alaska State Representative Scott Ogan .

　　Not so fast , say environmentalists . Sticking to the low end of government estimates , the National Resources Defense Council says there may be no more than 3.2 billion barrels of economically recoverable oil in the coastal plain of ANWR, a drop in the bucket that would do virtually nothing to ease Americas energy problems . And consumers would wait up to a decade to gain any benefits , because drilling could begin only after much bargaining over leases , environmental permits and regulatory review . As for ANWRs impact on the California power crisis , environmentalists point out that oil is responsible for only 1% of the Golden States electricity output and just 3% of the nations .

　　21. What does President Bush think of tapping oil in ANWR ?

　　A) It will exhaust the nations oil reserves .

　　B) It will help secure the future of ANWR.

　　C) It will help reduce the nations oil imports

　　D) It will increase Americas energy consumption

　　22. We learn from the second paragraph that the American oil industry _______

　　A) believes that drilling for oil in ANWR will produce high yields

　　B) tends to exaggerate Americas reliance on foreign oil

　　C) shows little interest in tapping oil in ANWR

　　D) expects to stop oil imports from Saudi Arabia

　　23. Those against oil drilling in ANWR argue that _________

　　A) it can cause serious damage to the environment

　　B) it can do little to solve U.S. energy problems

　　C) it will drain the oil reserves in the Alaskan region

　　D) it will not have much commercial value

　　24. What do the environmentalists mean by saying Not so fast ?

　　A) Oil exploitation takes a long time

　　B) The oil drilling should be delayed

　　C) Dont be too optimistic

　　D) Dont expect fast returns

　　25. It can be learned from the passage that oil exploitation beneath ANWRs frozen earth ________

　　A) remains a controversial issue

　　B) is expected to get under way soon

　　C) involves a lot of technological problems

　　D) will enable the U.S. to be oil independent

　　Passage 2

　　Every year television stations receive hundreds of complaints about the loudness of advertisements. However, federal rules forbid the practice of making ads louder than the programming. In addition, television stations always operate at the highest sound level allowed for reasons of efficiency. According to one NBC executive, no difference exists in the peak sound level of ads and programming. Given this information why do commercials sound so loud?

　　The sensation of sound involves a variety of factors in addition to its speak level. Advertisers are skilful at creating the impression of loudness through their expert use of such factors. One major contributor to the perceived loudness of commercials is that mush less variation in sound level occurs during a commercial. In regular programming the intensity of sound varies over a large range. However, sound levels in commercials tend to stay at or near peak levels.

　　Other tricks of the trade are also used. Because low-frequency sounds can mask higher frequency sounds, advertisers filter out any noises that may drown out the primary message. In addition, the human voice has more auditory impact in the middle frequency ranges. Advertisers electronically vary voice sounds so that they stay within such a frequency band. Another approach is to write the script so that lots of consonants are used, because people are more aware of consonants than vowel sounds. Finally, advertisers try to begin commercials with sounds that are highly different from those of the programming within which the commercial is buried. Because people become adapted to the type of sounds coming from programming, a dramatic change in sound quality draws viewer a attention. For example, notice how many commercials begin with a cheerful song of some type.

　　The attention-getting property of commercials can be seen by observing one-to-two-year-old children who happen to be playing around a television set. They may totally ignore the programming. However, when a commercial comes on, their attention is immediately drawn to it because of its dramatic sound quality.

　　1. According to the passage, the maximum intensity of sound coming from commercials _______.

　　A) does not exceed that of programs.

　　B) is greater than that of programs.

　　C) varies over a large range than that of programs.

　　D) is less than that of programs.

　　2. Commercials create the sensation of loudness because _______.

　　A) TV stations always operate at the highest sound levels.

　　B) their sound levels are kept around peak levels.

　　C) their sound levels are kept in the middle frequency ranges.

　　D) unlike regular programs their intensity of sound varies over a wide range.

　　3. Many commercials begin with a cheerful song of some kind because ________.

　　A) pop songs attract viewer attention.

　　B) it can increase their loudness.

　　C) advertisers want to make them sound different from regular programs.

　　D) advertisers want to merge music with commercials.

　　4. One of the reasons why commercials are able to attract viewer attention is that ________.

　　A) the human voices in commercials have more auditory impact.

　　B) people like cheerful songs that change dramatically in sound quality.

　　C) high-frequency sounds are used to mask sounds that drown out the primary message.

　　D) they possess sound qualities that make the viewer feel that something unusual is happening.

　　5. In the passage, the author is trying to tell us ________.

　　A) how TV ads vary vocal sounds to attract attention.

　　B) how the loudness of TV ads is overcome.

　　C) how advertisers control the sound properties of TV ads.

　　D) how the attention-getting properties of sounds are made use of in TV ads.

　　5 Passage 3

　　Im usually fairly skeptical about any research that concludes that people are either happier or unhappier or more or less certain of themselves than they were 50 years ago. While any of these statements might be true, they are practically impossible to prove scientifically. Still, I was struck by a report which concluded that todays children are significantly more anxious than children in the 1950s. In fact, the analysis showed, normal children ages 9 to 17 exhibit a higher level of anxiety today than children who were treated for mental illness 50 years ago.

　　Why are Americas kids so stressed? The report cites two main causes: increasing physical isolation -- brought on by high divorce rates and less involvement in community, among other things -- and a growing perception that the world is a more dangerous place.

　　Given that we cant turn the clock back, adults can still do plenty to help the next generation cope.

　　At the top of the list is nurturing a better appreciation of the limits of individualism. No child is an island. Strengthening social ties helps build communities and protect individuals against stress.

　　To help kids build stronger connections with others, you can pull the plug on TVs and computers. Your family will thank you later. They will have more time for face-to-face relationships, and they will get more sleep.

　　Limit the amount of virtual violence your children are exposed to. Its not just video games and movies; children see a lot of murder and crime on the local news.

　　Keep your expectations for your children reasonable. Many highly successful people never attended Harvard or Yale.

　　Make exercise part of your daily routine. It will help you cope with your own anxieties and provide a good model for your kids. Sometimes anxiety is unavoidable. But it doesnt have to ruin your life.

　　36. The author thinks that the conclusions of any research about peoples state of mind are______.

　　A) surprising B) confusing C) illogical D) questionable

　　37. What does the author mean when he says, we cant turn the clock back ?

　　A) Its impossible to slow down the pace of change.

　　B) The social reality children are facing cannot be changed.

　　C) Lessons learned from the past should not be forgotten.

　　D) Its impossible to forget the past.

　　38. According to an analysis, compared with normal children today, children treated as mentally ill 50 years ago____.

　　A) were less isolated physically

　　B) were probably less self-centered

　　C) probably suffered less from anxiety

　　D) were considered less individualistic

　　39. The first and most important thing parents should do to help their children is ____.

　　A) to provide them with a safer environment

　　B) to lower their expectations for them

　　C) to get them more involved socially

　　D) to set a good model for them to follow

　　40. What conclusion can be drawn from the passage?

　　A) Anxiety, though unavoidable, can be coped with.

　　B) Childrens anxiety has been enormously exaggerated.

　　C) Childrens anxiety can be eliminated with more parental care.

　　D) Anxiety, if properly controlled, may help children become mature.

　　Highways

　　Early in the 20th century, most of the streets and roads in the U.S. were made of dirt, brick, and cedar wood blocks. Built for horse, carriage, and foot traffic, they were usually poorly cared for and too narrow to accommodate automobiles.

　　With the increase in auto production, private turnpike companies under local authorities began to spring up, and by 1921 there were 387, 000 miles of paved roads. Many were built using specifications of 19th century Scottish engineers Thomas Telford and John MacAdam , whose specifications stressed the importance of adequate drainage. Beyond that, there were no national standards for size, weight restrictions, or commercial signs. During World War I, roads throughout the country were nearly destroyed by the weight of trucks. When General Eisenhower returned from Germany in 1919, after serving in the U.S.Armys first transcontinental motor convoy , he noted: The old convoy had started me thinking about good, two-lane highways, but Germanys Autobahn or motorway had made me see the wisdom of broader ribbons across the land.

　　It would take another war before the federal government would act on a national highway system. During World war Ⅱ, a tremendous increase in trucks and new roads were required. The war demonstrated how critical highways were to the defense effort. Thirteen per cent of defense plants received all their supplies by truck, and almost all other plants shipped more than half of their products by vehicle. The war also revealed that local control of highways had led to a confusing variety of design standards. Even federal and state highways did not follow basic standards. Some states allowed trucks up to 36,000 pounds, while others restricted anything over 7,000 pounds. A government study recommended a national highway system of 33,920 miles, and Congress soon passed the Federal-Aid Highway Act of 1944, which called for strict, centrally controlled design criteria.

　　The interstate highway system was finally launched in 1956 and has been hailed as one of the greatest public works projects of the century. To build its 44,000-mile web of highways, bridges and tunnels, hundreds of unique engineering designs and solutions had to be worked out. Consider the many geographic features of the country: mountains, steep grades, wetlands, rivers, deserts, and plains. Variables included the slope of the land, the ability of the pavement to support the load, the intensity of road use, and the nature of the underlying soil. Urban areas were another problem. Innovative designs of roadways, tunnels, bridges, overpasses, and interchanges that could run through or bypass urban areas soon began to weave their way across the country, forever altering the face of America.

　　Long-span, segmented-concrete. cable-stayed bridges such as Hale Boggs in Louisiana and the Sunshine Skyway in Florida, and remarkable tunnels like Fort McHenry in Maryland and Mt. Baker in Washington, met many of the nations physical challenges. Traffic control systems and methods of construction developed under the interstate program soon influenced highway construction around the world, and were invaluable in improving the condition of urban streets and traffic patterns.

　　Today, the interstate system links every major city in the U.S., and the U.S. with Canada and Mexico. Built with safety in mind, the highways have wide lanes and shoulders, dividing medians or barriers, long entry and exit lanes, curves engineered for safe turns, and limited access. The death rate on highways is half that of all other U.S. roads

　　By opening the North American continent, highways have enabled consumer goods and services to reach people in remote and rural areas of the country, spurred the growth of suburbs, and provided people with greater options in terms of jobs, access to cultural programs, health care, and other benefits. Above all, the interstate system provides individuals with what they cherish most: personal freedom of mobility.

　　The interstate system has been an essential element of the nations economic growth in terms of shipping and job creation: more than 75 percent of the nations freight deliveries arrive by truck; and most products that arrive by rail or air use interstates for the last leg of the journey by vehicle. Not only has the highway system affected the American economy by providing shipping routes, it has led to the growth of spin-off industries like service stations, motels, restaurants, and shopping centers. It has allowed the relocation of manufacturing plants and other industries from urban areas to rural.

　　By the end of the century there was an immense network of paved roads, residential streets, expressways, and freeways built to support millions of vehicles. The highway system was officially renamed for Eisenhower to honor his vision and leadership. The year construction began he said: Together, the united forces of our communication and transportation systems are dynamic elements in the very name we bear-United States. Without them, we would be a mere alliance of many separate parts.

　　Questions 47 to 56 are based on the following passage.

　　E1 Nino is the name given to the mysterious and often unpredictable change in the climate of the world. This strange 47 happens every five to eight years. It starts in the Pacific Ocean and is thought to be caused by a failure in the trade winds , which affects the ocean currents driven by these winds. As the trade winds lessen in 48 , the ocean temperatures rise, causing the Peru current flowing in from the east to warm up by as much as 5℃.

　　The warming of the ocean has far-reaching effects. The hot, humid air over the ocean causes severe 49 thunderstorms. The rainfall is increased across South America, 50 floods to Peru. In the West Pacific, there are droughts affecting Australia and Indonesia. So while some parts of the world prepare for heavy rains and floods, other parts face drought, poor crops and 51 .

　　E1 Nino usually lasts for about 18 months. The 1982-83 E1 Nino brought the most 52 weather in modern history. Its effect was worldwide and it left more than 2,000 people dead and caused over eight billion pounds 53 of damage. The 1990 E1 Nino lasted until June 1995.
