雅思阅读是非无判断题“not given"独家分析

雅思阅读是非无判断题“not given"独家分析 by 贾若寒选自《最新雅思阅读是非无判断题》一书第四章
是非无判断题Not Given考点分析 Unit 4 An Analysis of Not Given Reading Procedures 阅读步骤: Step 1: 在题目中划出定位词。 Step 2: 定位词在文章中定位。 Step 3: 若定位词在文章中无法定位，则看有无同义转换，若无同义转换，那么确定答案是Not Given。若在文章中可以定位题目中的定位词，那就要看一下几个方面来确定是Not Given： 1．
题目中有比较结构，在文章中出现此结构，但是比较的对象不同 2．
题目中用情态动词表示对未来的预测或者展望，而在文章中没有提及 3．
题目中有的相关修饰词（即考点词）在文章中没有相关的同义词的解释对应 4．
在文章中出现过题目中的定位词，但是通过结构多样性的比较，两者是没有关系的。Example:题目：The parents of top athletes have often been successful athletes themselves.文章：No one theory can explain improvements in performance, but the most important factor has been genetics. The athletes must choose his parents carefully. ……5. 时间对应信息不一致，导致主体信息无法判断Example:题目：There was little improvement in athletic performance before the twentieth century.文章：Since the early years of the twentieth century, when the International Athletic Federation began keeping records, there has been a steady improvement in how fast athletes run, how high they jump and how far they are able to hurl massive objects……. 除了以上这些方面之外，还有一些内容学要掌握以确定是否是Not Given。 Ⅰ. 题目中有比较结构，文章中无比较结构则答案判断为Not Given。 例一： 原文:
And the future? It is anticipated that, in the years to come, leisure spending will account for between a third to a half of all household spending, whilst it is difficult to give exact figures, the leisure industry will certainly experience a long period of sustained growth. 题目: In future, people will pay
less for the leisure facilities they use than they do today. 分析： 第一步：确定题目中的定位词和考点词（关键词）。本题中的定位词是leisure。另外，考点词是pay和一个表示比较结构less……than。 第二步; 定位词到原文中定位。Leisure在原文中出现了两次。Pay这个词在原文中出现了词性转换和同义转换，成为了另外一个词：spending。 第三步：原文中定位另外一个关键信息：比较结构。但是原文中并没有出现此结构因此确定答案是Not Given。    例二： 原文: Healthcare providers diagnose insomnia in several ways. One way is to categorize insomnia by how often it occurs. Another way is to identify the insomnia by what is causing the sleep deprivation. The two main types of insomnia have been described as Primary Insomnia and Secondary Insomnia.
Primary Insomnia is a chronic condition with little apparent association with stress or a medical problem. The most common form of primary insomnia is psychophysiological insomnia. Secondary insomnia is caused by symptoms that accompany a medical condition such as anxiety, depression or pain. 题目: Secondary insomnia is far more common than Primary insomnia. 分析：
第一步：确定题目中的定位词。定位词是两个专有名词Secondary insomnia和Primary insomnia。而本题的关键词则是far more common than的比较结构。 第二步; 定位词到原文中定位。文章中两次出现了以上两个专有名词。 第三步：原文中定位另外一个关键信息：比较结构。但是原文中并没有出现此结构因此确定答案是Not Given。                                   Ⅱ. 题目中有表示因果关系的表达方式，而原文中并没有此表述或相似结构，则答案判断为Not Given。 例： 原文:
Working hours are not expected to decrease, partly because the 24-hour society will need to be serviced; and secondly, because more people will be needed to keep the service/leisure industries running.        In the coming decades, the pace of change will accelerate generating greater wealth at a faster rate than ever before. Surveys show that this is already happening in many parts of <place wst="on">Europe</place>. The south-east of <place wst="on"><country-region wst="on">England</country-region></place>, for example, is now supposedly the richest area in the EEC. The ‘leisure pound’ is one of the driving forces behind this surge. 题目: The 24-hour society will have a negative effect on people’s attitudes to work.  分析：
 第一步：确定题目中的定位词。本题是明显的数字定位。24-hour society是明显的定位词。而本题中的关键词或考点词是表示结果的一个短语have a negative effect on。另外一个定位词是attitudes to work。 第二步; 定位词到原文中定位。24-hour society出现在原文的第一句。但是原文中无法定位任何表示因果关系的词组。而且通过浏览原文也无法搜索到有关people’s attitudes to work的信息。 因此，可以判断本题的答案是Not Given。             Ⅲ. 题目中有表示趋势的词组，而在原文中无法找到相关的表述，则答案判断为Not Given。  原文:
The future, we are told, is likely to be different. Detailed surveys of social and economic trends in the European Community show that <place wst="on">Europe</place>’s population is falling and getting older. The birth rate in the Community is now only three-quarters of the level needed to ensure replacement of the existing population. By the year 2020, it is predicted that more than one in four Europeans will be aged 60 or more and barely one in five will be under 20. In a five-year period between 1983 and 1988 the Community’s female workforce grew by almost six million. As a result, 51% of all women aged 14 to 64 are now economically active in the labour market compared with 78% of men. 题目: The rise in the female workforce in the European Community is a positive trend. 分析：
 第一步：确定题目中的定位词。本题中的定位词是两个专有名词female workforce和European Community，专有名词在文章中一般来说不会发生同义转化。而题目中的句子的表语a positive trend则是判断的关键。 第二步; 定位词到原文中定位。原文中的一句话In a five-year period between 1983 and 1988 the Community’s female workforce grew by almost six million. 同时提到题目中的两个关键词。而且原文中的grew和题目中的rise构成了同义词转化和词性转化。 第三步：原文中的关键词a positive trend在原文的定位句中并没有出现，而且通过上下文的信息搜索，也没有相关的任何信息，因此答案为not given。              Ⅳ. 题目中表示明确的作者意图，而在文章中无法清晰理解此意图，则答案判断为Not Given。。 例：
 原文:
I would suggest that foxes pose a greater problem, yet there is no passionate public campaign to oust foxes, presumably because it is obvious we can never eliminate the millions of wild foxes in <place wst="on"><country-region wst="on">Australia</country-region></place>. Yet the same common sense thinking is not applied to cats. It is thought instead that, if everyone would only spay their cats, string bells around their necks and keep them in at night, cats would no longer kill wildlife. But what of the millions of feral cats in our deserts and woodlands? They are the bigger problem, but they are no more controllable than foxes or cane toads. 题目: The author believes that all wild foxes should be killed.  分析：
第一步：确定题目中的定位词。本题中的定位词是wild foxes。而题目中的关键词（或称为考点词）的词是all和be killed。此外，另外一个核心的考点是The author believes……。 第二步; 定位词到原文中定位。原文的第一句提到了上述的定位词和考点词。文章原句是I would suggest that foxes pose a greater problem, yet there is no passionate public campaign to oust foxes, presumably because it is obvious we can never eliminate the millions of wild foxes in Australia.  第三步：比较题目和文章原句的含义： 题目的中文意思是：作者认为应该杀死所有的野生狐狸。 原文句子的意思是：我的观点是狐狸引起了更加严重的问题，但是公众却没有什么热情去开展活动驱逐狐狸，这大概是因为在澳洲要消灭所有的狐狸显然是不可能的。 通过比较我们发现作者的观点在原文中和题目中是没有共同点的。 所以本题判断为not given。       Ⅴ. 题目句子中的主谓宾结构在原文中无法对应，则答案判断为Not Given。 原文: In the last 20 years, scientists have detected an increasing variety of toxic contaminants in the North, including pesticides from agriculture, chemicals and heavy metals from industry, and even radioactive fall-out from <place wst="on"><city wst="on">Chernobyl</city></place>. These are substances that have invaded ecosystems virtually worldwide, but they are especially worrisome in the <place wst="on">Arctic</place>. 题目: Industry in the <place wst="on">Arctic</place> has increased over the last 20 years. 分析：
 第一步：确定题目中的定位词。定位词分别是时间表达式over the last 20 years，专有名词Arctic和主语Industry。另外，考点词是increased。 第二步：定位词到原文中定位。文章原句是: In the last 20 years, scientists have detected an increasing variety of toxic contaminants in the North, including pesticides from agriculture, chemicals and heavy metals from industry, 我们发现在原文中的时间对应词和题目中的相同，而Arctic在原文中也没有变化。而考点词在原文中转化成了increasing。原文的表述是
an increasing variety of toxic contaminants，说明增加的是variety of toxic contaminants，而题目中的主语是Industry。而industry在文章中的表述是……heavy metals from industry。但这并不能判断工业是否增长。所以本题判断为not given。                    Ⅵ. 题目和原文都有比较，但是比较对象不同，则答案判断为Not Given。  原文: Scientists have found that a smoked substance reaches the brain more quickly than one swallowed, snorted (such as cocaine powder) or even injected. 题目: Snorted substances reach the brain faster than injected substances.  分析：
 题目和原文都有比较，比较的关键词是reach the brain faster than，原文中有一个同义词转换结构reaches the brain more quickly than。其中faster和more quickly构成了同义词转换的用法。 题目中比较的两方面是Snorted substances和injected substances。而原文的比较内容是a smoked substance和swallowed, snorted (such as cocaine powder) or even injected。题目中的比较对象在原文中是并列关系，因此无法进行比较，所以答案判断为not given。   Ⅶ. 题目中表示现在状况，而文章中表示将来的可能性，则答案判断为Not Given；反之亦然。 原文: Nearly half the world’s population will experience critical water shortages by 2025, according to the United Nations (UN). Wars over access to water are a rising possibility in this century and the main conflicts in <place wst="on">Africa</place>
during the next 25 years could be over this most precious of commodities, as countries fight for access to scarce resources. 题目: Some African countries are currently at war over water resources.  分析：
