做过雅思阅读的同学们都知道要想拿到雅思阅读的高分，需要能很快的找到题目在原文中的对应处。所以，关键词是非常重要的。下面这篇就主要讲雅思阅读解题法宝之定位词解析。
雅思定位词变身之“同义替换”，这包含同义词或同义词组
剑6，Test4的Q9：KimSchaefer’s marketing technique may be open to criticism on moral grounds。题目中定位词为moral，在文章中定位，我们会在文章第三段中定位到“Sellingpharmaceuticals is a daily exercise in ethical judgment”，而其中ethical即为moral的同义词。
剑4，Test3的Q9：Any streetchild can set up their own small business if given enough support.此判断题中定位词实际上是词组“set up their ownsmall business ”，在文章中定位，我们会在文章中“Lessons learned” 的部分中定位到“Being an entrepreneur is not for everyone, not for every streetchild”。此处，文章中“Beingan entrepreneur”即为定位词的同义词组。
其他的同义词/词组变身如:
perceive→sense evolve →develop detect →find
mortal→people unbiased → objective
limb → armor leg waste→ unwanted material
resemble →look like dwelling → domestic building
雅思定位词之“近义替换”，这包含近义词或近义词组
剑7，Test1的Q8：However, evenbefore this was understood, the principle had been applied in the design ofinstruments which calculated the ____ of the seabed。 此题为在原文中选词填空的摘要题，定位词为“calculate”和“seabed”， 在文章中我们会定位到“Before this wasdiscovered, engineers had already built instruments to exploit the principle,for example to measure the depth of the sea under a ship”。此处“measure”即为“calculate”的近义词，而“sea”即为“seabed”的上义词。
其他的近义词/词组变身如：
salary →wage statement → comment
be gainedfrom → derive from policy → initiative
valuable →important break down → subdivide
雅思定位词之“派生词”
剑6，Test3的Q33：Monkeys wereless likely to become diabetic。此题为分类题，定位词为“diabetic”，在文章中定位，我们能定位到句子“…and they have more normal blood glucose levels(pointing to areduced risk for diabetes, which is marked by usually high blood glucoselevels)”。题目中定位词“diabetic”为名词，意为“糖尿病患者”，而文章中的“diabetes”也为名词，但意为“糖尿病”，是“diabetic”的派生词。
剑4，Test4的Q14：archaeologyinvolves creativity as well as careful investigative work。 此题为是非无判断题，定位词为“creativity”和“investigative”，在文章中我们能定位到“Archaeology is partly the discovery of the treasures of thepast,…partly the exercise of the creative imagination…it is investigating thesewers of Roman Britain”。题目中定位词“creativity”为名词，在文章中对应形式“creative”(形容词)为它的派生词，;定位词“investigative”为形容词，在文章中对应形式“investigate”(动词)为它的派生词。
其他的派生词变身如：
recover →recovery evolutionary → evolve
erosion →erode
雅思定位词之“反义词的否定形式”
StickingPower中的Q15：What makes sticky insects feetspecial is the fact that they can also detach themselves easily from a surface。
此题属于人名理论配对，题目中定位词为 detach。到文章中去定位，我们会定位到“’There are lots of ways to make two surfaces stick together, butthere are very few which provide precise and reversible attachment’ says StasGorb”，句中attachment实际上为detach的反义词attach的名词形式，而reversible表示可逆的，因此reversible attachment即为detach的反义词(组)的否定形式。
其它的反义词否定形式变身如：similar → not unusual
雅思定位词之“上义词/词组”
剑6，Test3的Q28：Studies showdrugs available today can delay the process of growing old。此题为是非无判断题，定位词为“drugs”，在文章中定位，我们能在文章第一段定位到“As researcherson aging noted recently, no treatment on the market today has been proved toslow human aging –the build-up of molecular and cellular damage that increasesvulnerability to infirmity as we get older”。文章中“treatment”即为定位词“drugs”的上义词。
剑4，Test2的Q8：Young peopleoften reject the established way of life in their community。此题为人名理论配对题，题目中信息量较大，需要根据词组“rejectthe established way of life in their community”来定位，到文章中定位，我们会定位到“When the next generation reaches their teens, they might not wantto be induced into the old traditions”。此处，“the old traditions”即为题目中“the established way of life in their community”的上义词组。
剑5，Test3的Q27：how AI mighthave a military impact。此题为段落信息配对题，定位词为“military”，在文章中定位，我们会在E段定位到“HNC claimthat their system based on a cluster of 30processors, could be used to spot camouflagedvehicles on a battlefield or …”，句中“battlefield”即为“military”的下义词。
其它的下义词/词组变身如：military → weapon / the SecondWorld War
雅思定位词之“原词”，即没有变身。这种情况多发生在定位词是专有名词、专业术语或实义名词时。
剑7，Test3的Q28：Problems inNordic countries were excluded because they are outside the European EconomicCommunity，此题为是非无判断题，定位词为“Nordic countries”。在文章中定位，我们能够在第一段定位到“Those confined to particular geographical areas, such as countriesbordering the Mediterranean or the Nordic countries therefore had to bediscarded”，句中的“Nordiccountries”即为定位词原词。
